These following tips may help you make a good impression on your job interviewer during the interview:
Before entering enquire by saying, "May I come in sir/madam?".
If the door was closed before you entered, make sure you shut the door behind you softly.
Look at the interviewer and confidently say 'Good day sir/madam'.
If the interviewer wants to shake hands, then offer a firm grip first maintaining eye contact and a smile.
Seek permission to sit down. If the interviewer is standing, wait for them to sit down first before you take your seat.
An alert interviewee would diffuse the tense situation with light-hearted humor and immediately set rapport with the interviewer.
The interviewer normally pays more attention if you display an enthusiasm in whatever you say. This enthusiasm comes across in the energetic way you put forward your ideas.
You should maintain a cheerful disposition throughout the interview.
A little humor or wit thrown in the discussion occasionally enables the interviewer to look at the pleasant side of your personality.
You must maintain eye contact with the interviewer. This shows your self-confidence and honesty. Many interviewees while answering questions, tend to look away. This conveys you are concealing your own anxiety, fear and lack of confidence. Maintaining an eye contact is a difficult process. As the circumstances in an interview are different, the value of eye contact is tremendous in making a personal impact.
Interviewers appreciate a natural person rather than an actor. It is best for you to talk in natural manner because then you appear genuine.
The writer attitude is _______.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Alaska is disappearing slowly, but surely. It is estimated that since the 19505, as much as fifteen percent of Alaska's land area has disappeared. How can a whole state be disappearing? The problem is that Alaska’s glaciers are melting. The state has more than 100,000 glaciers. These glaciers account for about 75,000 square kilometers, or five percent, of the state’s area. That is an area of land larger than Ireland!
According to a recent report by the US Geological Survey, ninety-nine percent of Alaska's glaciers are either retreating or diminishing. This diminishing seems mainly due to the increase in global temperatures. Since the 19605, the average year-round temperature has increased by almost 3°C. Additionally, the average winter temperature has increased by over 6°C. Presently, an estimated 100 cubic kilometers of ice is disappearing from Alaskan glaciers every year. It may be even more in the near future, as some scientists predict that the average world temperature could go up 4 to 7°C by the year 2100.
Another problem facing Alaska is its thawing permafrost. Much of the land in Alaska used to be permanently frozen or frozen for most of the year. Now, the thawing permafrost is causing a number of problems for people living in Alaska. Roads and utility poles are collapsing as the ground around and under them warms and soften. Also, the hard permafrost that originally prevented beaches from eroding during violent storms is now melting. People who live along Alaska's coasts are being forced to relocate. For villages on small low islands, one terrible storm could wipe out the entire community.
The melting permafrost and increasing temperatures are both affecting the forests of Alaska. As the permafrost under the forests melts, insects that normally do not turn up until the warmer seasons are appearing sooner. The spruce-bark beetle, for example, is increasing in numbers as a result of warmer winter temperatures. It usually takes about two years for these beetles to grow and reproduce in. very cold weather. However, due to the increase in temperatures, spruce-bark beetles are reproducing faster and damaging as many trees in one year as they previously damaged in two. If something cannot be done to change things, Alaska's forests will not survive the turn of the century.
Some scientists believe that human activity is linked to a global increase in weather temperature.
Whatever the cause of rising temperatures may be, the fact remains that temperatures are warming, affecting Alaska for the worse. Horribly, this could be a preview of what will happen to the rest of the world in the next century.What does the word “they” in paragraph 4 refer to?

These days it is easy for most of us to get a hold of the latest books or magazines. We can go to bookstores, order them through the Internet, or borrow them from the local libraries. Now imagine having to walk miles and miles through a hot sandy desert just to borrow a book. This is the reality for people living in the villages of the Carissa region of Kenya in East Africa.
In 1996, librarian Wycliffe Oluoch used to spend each day waiting for people to come to borrow some of the 24,000 books in his library in Carissa. The library had no shortage of books, but people weren’t coming to read them. It was too much effort to walk through the desert just to borrow books. Oluoch racked his brain for ways to entice people into the library. After a lot of thought, he hit upon a great idea. If people wouldn’t come to the library, then he would have to take the library to them. Oluoch strapped boxes of books onto the backs of camels, and created the Mobile Camel Library.
Starting with three camels in 1996, but more recently expanding the service to six camels, the Mobile Camel Library serves over one million people. Twice a month, the camel library can be seen carrying books all around the Carissa region. These hard-working animals need little water and can carry up to 500 pounds of books across the sands. A librarian, a library assistant, a herdsman, and a lookout all travel with the camels. The lookout helps protect the books from thieves.
The children of Carissa love the camel library and appreciate Oluoch’s effort. Eleven-year-old Mohamud Mohamed reads his library books carefully and always returns them on time. He knows the Carissa library punishes people for losing books, just like any other library. However, the punishment is very stiff compared to that of other libraries. If a village loses a book, the camel library stops visiting.aThe phrase “racked his brain” probably means .

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Most people need some preparation before they are ready for the workforce, and planning should begin long before it is time to start a career.
Many high school students don't yet know what they want to do. High school is a great time to start thinking about careers. Settling on just one occupation in high school isn't necessary, but they should know how to explore careers and put time into investigating them and learning about their skills and interests.
Understanding what you enjoy what you are good at is the first step in exploring careers. It is important to think about what you like to do because work will eventually be a big part of your life. Once you have thought about the subjects and activities you like best, the next step is to look for careers that put those interests to use. If you love sports, for example, you might consider a career as a gym teacher, or coach.
Another approach to identifying potential career interests is to consider local employers and the types of jobs they have. There are many jobs in manufacturing and healthcare near the high school. Talking directly to workers can help you get information about what they do. If you don't know workers in occupations that interest you, ask people such as your parents, friends, or teacher for their contacts.
If job shadowing give you taste of what an occupation is like, imagine how helpful getting experience could be. Students can begin getting career-related experiences in high school through internships, employment, and other activities. Completing an internship is an excellent way to get experience. Internships are temporary, supervised assignments designed to give student practical job training.Which of the following is NOT mentioned as the way to identify career interests?

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Around the year 1500, hunting people occupied the entire northern third of North America. They lived well from the animals with which they shared these lands. Hunters of sea mammals had colonized the Arctic coasts of Canada and Greenland between four and five thousand years before. Land-hunting people had lived throughout much of the northern interior for at least 12,000 years.
Northern North America is part of a larger circumpolar ecological domain that continues across the narrow Bering Strait into Siberia and northern Europe. The overall circumpolar environment in the 1500's was not very different from the environment of the present. This vast landmass had a continental climate and was dominated by cold arctic air throughout a long winter and spring season. Summer temperature ranged from near freezing to the mid-20's Celsius, while winter temperature were often as low as 40 degrees below zero Celsius.
Geographers divide the overall circumpolar domain into two zones, the Arctic and, below it, the Subarctic. They refer to the landforms of these areas as tundra and taiga, respectively.
Temperatures in the northern lands were below freezing for eight or nine months of the year. Subsurface soil in the Arctic's tundra remained permanently frozen. Even when summer temperatures were above freezing and the top inches of earth became saturated with water, the soil below remained frozen into a permafrost, as hard as rock. When water flowed upon the surface of permanently frozen tundra, it made overland travel extremely difficult. Summer travel in the boggy lands, or muskeg country, of the Sub Arctic’s taiga was also slow and arduous. Tracking animals was more difficult than it was during the winter when the swampy ground was frozen solid and covered with snow. In both tundra and taiga, hordes of mosquitoes and biting flies bred in the standing pools of water. Clothing lost its thermal efficiency when it became damp. Northern people looked forward to the turn of the season to bring the easier traveling conditions associated with cold weather. In the Arctic, they could haul food and supplies by dogsled while in the Subarctic; people could travel quickly and efficiently by snowshoes and toboggan.All of the following are mentioned as having made travel in the summer difficult EXCEPT

Preparation is a key to a successful interview. Does the idea of going to a job interview make you feel a little nervous? Many people find that it is the hardest part of the employing process. But it is not really true. The more you prepare and practice, the more comfortable you will feel. You should find out as much as possible about the company before you go to the interview. Understand the products that they produce and the services that they provide. It is also good to know who the customers are and who the major competitors are. Practice makes perfect. It will also make you feel more confident and relaxed. So, practice your answers to common questions. Make a list of questions to ask, too. Almost all interviewers will ask if you have questions. This is a great opportunity for you to show your keenness, enthusiasm, and knowledge.
Make a great impression. The interview is your chance to show that you are the best person for the job. Your application or resume has already exhibited that you are qualified. Now it is up to you to show how your skills and experience match this position and this company. The employer will be looking and listening to determine if you are a good fit. He/she will be looking for a number of different qualities, in addition to the skills that you possess. To make the best impression, dress appropriately; express your strengths; arrive early, by about 10-15 minutes; be enthusiastic; shake hands firmly; be an active listener; sit up straight and maintain eye contact; and ask questions
After the interview, follow up with a thank-you note. This is a chance for you to restate your interest and how you can benefit the company. Your best bet is to try to time it so that the note gets there before the hiring: decision is made. You should also follow up with a phone call if you do not hear back from the employer within the specified time.What does the writer advise you to practice?

Ambient divers are, unlike divers who go underwater in submersible vehicles of pressure resistant suits, exposed to the pressure and temperature of the surrounding ambient water. Of all types of diving, the oldest and simplest is free diving. Free divers may use no equipment at all, but most use a face mask, foot fins, and a snorkel. Under the surface, free divers must hold their breath. Most free divers can only descend 30 to 40 feet, but some skilled divers can go as deep as 100 feet.
Scuba diving provides greater range than free diving. The word scuba stands for self-contained underwater breathing apparatus. Scuba divers wear metal tanks with compressed air or other breathing gases. When using open-circuit equipment, a scuba diver simply breathes air form the tank through a hose and releases the exhaled air into the water. A closed-circuit breathing device, also called a rebreather, filters out carbon dioxide and other harmful gases and automatically adds oxygen. This enables the diver to breathe the same air over and over. In surface-supplied diving, divers wear helmets and waterproof canvas suits. Today, sophiticated plastic helmets have replaced the heavy copper helmets used in the past.These divers get their air from a hose connected to compressors on a boat. Surface-supplied divers can go deeper than any other type of ambient diver.According to the passage, a free diver may use any of the following EXCEPT ....................

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Robots are useful for exploring and working in space. In particular, many robots have been sent to explore Mars. Such robots have usually looked like a box with wheels. Though these robots are useful, by their very nature they are unreliable, extremely expensive, and they break easily. Also, they cannot do very many tasks. Because of these problems, scientists have been developing a new and unusual kind of robot. These new robots move like snakes, so they have been given the name "snakebots."
The way a snake is shaped lets it get into very small spaces, like cracks in rocks. It can also push its way below the ground or climb up different kinds of objects, like high rocks and trees. Such abilities account for the usefulness of a robot designed like a snake. A snakebot would be able to do these things, too, making it much more effective than regular robots with wheels, which easily get stuck or fall over. Since they can carry tools, snakebots would be able to work in space, as well. They could, for example, help repair the International Space Station.
But how can such a robot shape be made? A snakebot is built like a Chain made of about thirty parts, or modules. Each module is basically the same in that they all have a small computer and a wheel to aid movement. The large computer in the "head” of the snake makes all of the modules in a snakebot work together.
The modular design of the snakebot has many advantages. If one module fails, another can be added easily. Snakebot modules can also carry different kinds of tools, as well as cameras. Since each module is actually a robot in itself, one module can work apart from the rest if necessary. That is, all the modules can separate and move on their own, and then later, reconnect back into a larger robot.
Researchers are also trying to develop snakebots made of a special kind of plastic that can change its shape using electricity, almost like animal muscles. Snakebots made with this plastic will be very strong and hard to break.
Overall, the snakebot design is much simpler than that of common robots. Thus, snakebots will be much less expensive to build. For example, a robot recently sent to Mars cost over a hundred million dollars, whereas snakebots can cost as little as a few hundred dollars. With their versatility and affordability, snakebots seem to be the wave of the future, at least as far as space robots are concerned.The word "separate" in paragraph 4 mostly means .

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
During the past half-century, our species has embarked on a remarkable social experiment. For the first time in human history, great numbers of people - at all ages, in all places, of every political persuasion - have begun settling down as singletons. Until the second half of the last century, most of us married young and parted only at death. If death came early, we remarried quickly; if late, we moved in with family, or they with us. Now we marry later. We divorce, and stay single for years or decades.
The rise of living alone has produced significant social benefits, too. Young and middle-aged solos have helped to revitalise cities, because they are more likely to spend money, socialise and participate in public life. Contemporary solo dwellers in the US are primarily women: about 18 million, compared with 14 million men. The majority, more than 16 million, are middle-aged adults between the ages of 3S and 64. The elderly account for about 11 million of the total. Young adults between 18 and 34 number increased more than 5 million, compared with 500,000 in 1950, making them the fastest-growing segment of the solo-dwelling population.
Despite fears that living alone may be environmentally unsustainable, solos tend to live in apartments rather than in big houses, and in relatively green cities rather than in car-dependent suburbs. There's good reason to believe that people who live alone in cities consume less energy than if they coupled up and decamped to pursue a single-family home.The word "decamped" in paragraph 3 means .

Millions of people tune into the weather forecast each evening on televisions. Most of them imagine that the presenter does little more than arrive at the studio a few minutes before the broadcast, read the weather, and then go home.
In fact, this imagine is far from the truth. The two-minute bulletin which we all rely on when we need to know tomorrow’s weather is the result of a hard day’s work by the presenter, who is actually a highly-qualified meteorologist.
Every morning after arriving at the TV studios, the first task of the days is to collect the latest data from the national Meteorological Office. This office provides up-to-the- minute information about weather conditions throughout the day, both in Britain and around the world. The information is very detailed and includes predictions, satellite and radar pictures, as well as more technical data. After gathering all the relevant material from this office, the forecaster has to translate the scientific terminology and maps into images and word which viewers can easily understand.
The final broadcast is then carefully planned. It is prepared in the same way as other programmes. The presenter decides what to say and in what order to say it. Next, a “story board” is drawn up which lay out the script word for word. What make a weather forecast more complicated than other programmes are the maps and electronic images which are required. The computer has to be programmed so that the pictures appear in the correct order during the bulletin.
The time allocated for each broadcast can also alter. This is because the weather report is screened after the news, which can vary in length. The weather forecaster doesn’t always know how much time is available, which means that he/ she has to be thoroughly prepared so that the material can be adapted to the time available.
Another related complication is that the weather forecast has to be a live broadcast; it cannot be pre- recorded. Live shows are very nerve- racking for the presenter because almost anything can go wrong. Perhaps the most worrying aspect for every weather
forecaster is getting the following day’s predictions wrong. Unfortunately for them this is not an unusual occurrence; the weather is not always possible to predict accurately.
The weather is a national obsession in Britain, Perhaps because it is so changeable. It’s the national talking point, and most people watch at least one daily bulletin. It can be mortifying for a weather man or woman who has predicted rain for the morning to wake up to brilliant sunshine. These days, a weather forecaster’s job is even more complicated because they are replied upon to predict other environmental conditions. For example, in the summer the weather forecast has to include the pollen count for hay fever sufferers. Some also include reports on ultraviolet radiation intensity to help people avoid sunburn.
The job of the weather forecaster is certainly far more complicated than just pointing at a map and describing weather conditions. It’s a job for professionals who can cope with stressful and demanding conditions.What perception do most people have a weather forecasters?

Boots has reduced the price of "feminine" razors to bring them in line with men's. The chemist chain says it is just an isolated incident, but campaigners say it is part of a "pink tax" that discriminates against women. Who's right and what's the bigger story, ask Jessica McCallin and Claire Bates. Campaigners against what's been dubbed the "pink tax" - where retailers charge women more than men for similar products - are celebrating after Boots said it would change the price of some of its goods.
Stevie Wise, who launched the petition, was driven by a Times investigation which claimed that women and girls are charged, on average, 37% more for clothes, beauty products and toys. The New York Department of Consumer Affairs had compared the prices of 800 products with male and female versions and concluded that, after controlling for quality, women's versions were, on average, 7% more expensive than men's.
“This is a very exciting response,” says Wise. We are delighted with Boots' decision, but we now need to get them to look at all of their products, not just the ones highlighted in the petition. We hope this decision is just the first of many and we may broaden our campaign to focus on other retailers as well." Wise says that women have been getting in touch with examples of other price discrepancies from lots of companies and says there seems to be a particular problem with toys and clothes. Argos has been criticized for identical scooters that cost £5 more if they were pink rather than blue. Argos said it was an error that had already been rectified and that it would never indulge in differential pricing.
Among the examples sent to Wise was Boots selling identical child car seats that cost more in pink. Another retailer was selling children's balance bikes which cost more for a flowery print aimed at girls than a pirate print aimed at boys. But the latter example already appears to have been tweaked on the retailer's website, albeit by applying a £10 discount to the flowery version.
When challenged over sexist pricing, both Levi's and Tesco argued that different versions of things could have different production costs even if appearing fairly similar. Prof Nancy Puccinelli says her research suggests that women are much more careful shoppers than men, better able to scrutinise adverts and pricing gimmicks. She wonders if women are perceiving more value in the more expensive products. “If products are separated into male and female sections far away from each other it's harder to scrutinise prices.” Such a situation could either be deliberate or accidental but the campaigners are not convinced.
There is an opportunity for some companies, argues Olchawski. “The finding shows the power of marketing in our lives, how it shapes our perception of what it means to be a man or a woman. Some companies could choose not to play into this, not to play into the stereotypes and rip women off, but launch products more in tune with moves toward gender equality.”After comparing the prices of 800 products with male and female versions, the New York Department of Consumer Affairs _.

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
If "suburb" means an urban margin that grows more rapidly than its already developed interior, the process of suburbanization began during the emergence of the industrial city in the second quarter of the nineteenth century. Before that period the city was a small highly compact cluster in which people moved about on foot and goods were conveyed by horse and cart. But the early factories built in the 1830's and 1840's were located along waterways and near railheads at the edges of cities, and housing was needed for the thousands of people drawn by the prospect of employment. In time, the factories were surrounded by proliferating mill towns of apartments and row houses that abutted the older, main cities.
As a defense against this encroachment and to enlarge their tax bases, the cities appropriated their industrial neighbors. In 1854, for example, the city of Philadelphia annexed most of Philadelphia County. Similar municipal maneuvers took place in Chicago and in New York. Indeed, most great cities of the United States achieved such status only by incorporating the communities along their borders.
With the acceleration of industrial growth came acute urban crowding and accompanying social stress conditions that began to approach disastrous proportions when, in 1888, the first commercially successful electric traction line was developed. Within a few years the horse-drawn trolleys were retired and electric streetcar networks crisscrossed and connected every major urban area, fostering a wave of suburbanization that transformed the compact industrial city into a dispersed metropolis. This first phase of mass-scale suburbanization was reinforced by the simultaneous emergence of the urban Middle class 64whose desires for homeownership in neighborhoods far from the aging inner city were satisfied by the developers of single-family housing tracts.It can be inferred from the passage that after 1890 most people traveled around cities by

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions:
Atomic were once thought to be fundamental pieces of matter, but they are in turn made of smaller subatomic particles There are three major subatomic particles neutrons, protons, and electronic. Protons and neutrons can be broken into even smaller units, but these smaller units not occur naturally in nature and are thought to only be produced in manmade particle accelerators and perhaps in extreme stellar events like supernovas. The structure of an atom can best be described as a small solar system, with the neutrons at the center and the electrons circling them in various orbits, just as the planets circle the sun. In reality, the structure of an atom is far more complex, because the laws of physics are fundamentally different at the atomic level than at the level of the observable word. The true nature of atomic structure can only be expressed accurately through complex mathematical formulas. This explanation, however, is of little use to most average people.
Protons and neutrons have nearly equal mass and size, but protons carry a positive electrical charge, while neutrons carry no charge at all. Protons and neutrons are bound together by the strong nuclear force, one of the four basic forces in the universe. Protons and neutrons give atoms some of their most basic properties. Elements are defined by two numbers: their atomic number, which is equal to the number of protons they have, and their atomic weight, which is equal to total number of their neutrons and protons. In most lighter atoms, the number of neutrons and protons is equal, and the element is stable. In heavier atoms, however, there are more neutrons than protons, and the element is unstable, eventually losing neutrons through radioactive decay until a neutral state is reached.
Electrons are negatively charged particles. They are bound to their atoms through electromagnetic attraction. Opposite electrical charges attract one another, so the positive charge of the proton helps to keep the negatively charged electron in orbit around the nucleus of the atom. Electrons are different from neutrons in that they cannot be broken down into smaller particles. They are also far smaller and lighter than neutrons and protons. An electron is about one thousandth of the diameter of a proton and an even smaller fraction of its mass. Electrons circle the protons and neutrons at the center of the atom in orbits. These orbits are often called electron shells. The closer the orbit is to the center of the atom, the lower its energy is. There are seven electron shells, and each higher level can hold more electrons than the previous shell. Electrons naturally seek to occupy the lowest shell possible. So, if there is space in a lower shell, an electron will drop down to occupy that space. At temperatures higher than a few hundred degrees, electrons will gain energy and move to a higher shell, but only momentarily. When the electrons drop back down to their natural shell, they emit light. This is why fires and other very hot objects seem to glow.
Electrons are also primarily responsible for many of the chemical properties of atoms. Since electrons seek to occupy the lowest electron shell possible, they will move from one atom to another if there is a space available in a lower electron shell. For example, if there is an atom with an open space in its third shell, and it comes into contact with an atom with electrons in its fourth shell, the first atom will take one of these electrons to complete its third shell. When this happens, the two atoms will be chemically bonded to form a molecule. Furthermore, atoms sometimes lose electrons in collisions with other atoms. When this happens, the radio of protons and electrons in the atom changes, and therefore, the overall electrical charge of the atom changes as well. These atoms -

Cooking shows on TV are usually all about exotic foods. Thanks to globalization, people everywhere are introducing their taste buds to dishes from every corner of the world. At the same time, other people are discovering that food from their area is the best kept secret. In the past few years, this movement of purchasing local produce keeps picking up steam because it offers a lot of benefits. For starters, local food is often tastier because it is fresher. Goods that are imported from abroad must be flown or shinped in from far away, so they naturally lose some of their freshness during the journey. A simple way to test this is to sample a banana from overseas versus one that was grown locally and compare the tastes. Imported goods must also be washed and packaged in plastic or other containers so they can survive the journey. These materials may cause the nutritional value of these goods to decline during the shipping process. Food safety is another reason why people are choosing local produce. Today's laws regarding foods vary from country to country. This causes confusion and makes it difficult to detect if any harmful pesticides were used. When you know the local farmer who grows your food and the fields that are used to produce it, the chances of it being contaminated are greatly reduced.
Buying local foods can also have beneficial impact on the environment. By supporting local growers, consumers can maintain green space and farmland in their communities. Buying locally also helps to build the local community. If farmers can sell directly to consumers instead of a middleman, they will earn more money for their families. Additional profits also enable farmers to better care for their soil and keep quality standards high. In the end, it is a win-win situation for both parties.
If you are interested in incorporating more local foods into your diet, you can start by attending a farmers' market in your area. This is an open market where farmers sell fruits, vegetables, and meat directly to the public. If you have any questions about the production process or quality of these goods, you can ask the farmers directly. Once you experience the freshness of local foods for yourself, it might be tough to go back to the supermarket.The tone of the passage is .

Today, there are 600 million cars in the world. They may seem like a lot. However, there are over 7 million people on our planet. Most of the world’s population uses public transportation to get around. The number of people using public transportation continues to rise. Subway systems worldwide carry 155 million passengers each day. That’s more than 30 times the number carried by all the world’s airplanes. Every day in Tokyo passengers take more than 40 million rides on public transportation.
Yet many people see public transportation as ‘a depressing experience’, says author Taras Gresco. They say it is slow, crowded, or too expensive. In fact, Gresco says, it is actually ‘faster, more comfortable and cheaper’ than driving a car.Like millions of people, Taras Gresco is a ‘straphanger’ - a person who rides public transportation. In his book straphanger: Saving Our Cities and Ourselves from the Automobile, Gresco describe the benefits of public transportation. Firstly, it is better for the environment. When people use public transportation, they use less fuel. Twenty people on one bus use much less fuel than 20 people in 20 cars. Fewer cars mean less pollution and cleaner air.
Using public transportation can be good for your health in other ways. It can even help you lose weight. In one study, a group of people took public transportation every day for six months. Each day they walked to a bus stop or train station. In six months, each person lost an average of six pounds - almost three kilograms. Taking public transportation has another benefit, says Gresco. It helps people become part of their community. When you are alone in your car, you don’t talk to anyone. One Tokyo straphanger told Gresco, “To use public transport is to know how to cooperate with other people,’ It teaches you ‘how to behave in a public space’. So, public transportation is more than a way to get to work or school. It can help lead to cleaner cities. It may also lead to a healthier and more cooperative world population.How does the environment benefit from people’s use of the public transportation ?
