Birds have evolved many physical attributes that contribute to their flying ability. Wings are important, but adjustable tails, large hearts and light bones play critical roles.
To fly, birds, like airplanes, move air across their wings. Wings are designed so that air above the wings is forced to move faster than air below the wing. This creates higher pressure under the wings, called lift, which pushes the bird up. Different wing types evolved for different ways of flying. Prolonged flight requires long wings and an ability to soar. Other birds need superior maneuverability. Finches and sparrows
have short, broad wings. Faster birds, like hawks, have built-in spoilers that reduce turbulence while flying. This allows a steeper angle of attack without stalling.
Tails have evolved for specialized use. The tail acts like a rudder helping birds steer. Birds brake by spreading out their tails as they land. This adaptation allows them to make sudden, controlled stops-an essential skill, since most birds need to land on individual branches or on prey.
Flight takes muscle strength. If body builders has wings, they still could not flap hard enough to leave the ground. Birds have large, specialized hearts that beat much faster than the human heart and
provide the necessary oxygen to the muscles. The breast muscle accounts for 15 percent of the bird’s body weight. On pigeons, it accounts for a third of their total body weight.
Birds carry no excess baggage; they have hollow feathers and hollow bones with struts inside to maintain strength, like cross beams in a bridge. Birds fly to find prey, escape predators, and attract mates- in other words, to survive.

What does the author imply about the body builders having wings?

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:
At 7 pm on a dark, cold November evening, thousands of people are making their way across a vast car park. They're not here to see a film, or the ballet, or even the circus. They are all here for what is, bizarrely, a global phenomenon: they are here to see Holiday on Ice. Given that most people don’t seem to be acquainted with anyone who's ever been, the show's statistics are extraordinary: nearly 300 million people have seen Holiday on Ice since it began in 1943; it is the most popular live entertainment in the world.
But what does the production involve? And why are so many people prepared to spend their lives travelling round Europe in caravans in order to appear in it? It can't be glamorous, and it's undoubtedly hard work. The backstage atmosphere is an odd mix of gym class and workplace. A curtained-off section at the back of the arena is laughably referred to as the girls' dressing room, but is more accurately described as a corridor, with beige, cracked walls and cheap temporary tables set up along the length of it. Each girl has a small area littered with pots of orange make-up, tubes of mascara and long false eyelashes.
As a place to work, it must rank pretty low down the scale: the area round the ice-rink is grey and mucky with rows of dirty blue and brown plastic seating and red carpet tiles. It's an unimpressive picture, but the show itself is an unquestionably vast, polished global enterprise: the lights come from a firm in Texas, the people who make the audio system are in California, but Montreal supplies the smoke effects; former British Olympic skater Robin Cousins is now creative director for the company and conducts a vast master class to make sure they're ready for the show's next performance.
The next day, as the music blares out from the sound system, the case start to go through their routines under Cousins' direction. Cousins says, 'The aim is to make sure they're all still getting to exactly the right place on the ice at the right time - largely because the banks of lights in the ceiling are set to those places, and if the skaters are all half a metre out they'll be illuminating empty ice. Our challenge, ' he continues, 'is to produce something they can sell in a number of countries at the same time. My theory is that you take those things that people want to see and you give it to them, but not in the way they expect to see it. You try to twist it. And you have to find music that is challenging to the skaters, because they have to do it every night.'
It may be a job which he took to pay the rent, but you can’t doubt his enthusiasm. 'They only place you'll see certain skating moves is an ice show,' he says, 'because you're not allowed to do them in competition. It's not in the rules. So the ice show word has things to offer which the competitive world just doesn't. Cousins knows what he's talking about because he skated for the show himself when he stopped competing - he was financially unable to retire. He learnt the hard way that you can't put on an Olympic performance every night. I'd be thinking, these people have paid their money, now do your stuff, and I suddenly thought, "I really can't cope. I'm not enjoying it".' The solution, he realized, was to give 75 per cent every night, rather than striving for the sort of twice-a-year excellence which won him medals.
To be honest, for those of us whose only experience of ice-skating is watching top-class Olympic skaters, some of the movements can look a bit amateurish, but then, who are we to judge? Equally, it's impossible not to be swept up in the whole thing; well, you'd have to try pretty hard not to enjoy it.

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:
The blue whale is the largest animal ever known to  have existed. During the 20th century,  the species was almost exterminated due to commercial whaling. The species has slowly recovered following the global whaling ban but it remains endangered and faces a  number of  serious threats including ship strikes and the impact of climate change.
Blue whales are simply enormous with most ranging in length from 24-30 m. The largest  ever recorded was a gargantuan 33.5 m long. Females are up to 10 m longer than males. And they can weigh up to 200 tonnes. Just to put that in perspective: an adult male African elephant weighs 6 tonnes. The blue whale's heart is the size of a small car and its beat can be detected two miles away. But that's nothing compared to their calls. Blue whales are the loudest animals on earth and their calls are louder than a jet engine: reaching 188 decibels, while a jet's engine hit 'just' 140 decibels. Apart from their gigantic size, blue whales can be identified by their relatively small dorsal fin, a fairly rounded rostrum (anterior part of the skull), and approximately 90 ventral  grooves, which reach the navel. They also have row of 300-400 baleen plates on each side of the mouth, which are black in color and range in length from 50 cm in front to 100 cm in back.
Blue whales mostly travel alone or in groups of 2-3. Larger groups of up to 60 whales have been reported and are probably associated with feeding grounds. However, the blue whale has the most powerful voice in the animal kingdom and its low-frequency sounds can travel in deep water over hundreds, or even thousands, of miles. Under these circumstances, animals which may appear to us to be traveling alone may actually be in constant contact with one another.
At birth, a blue whale calf is the largest baby on earth: approximately 8m long and weighing about 4 tonnes. They grow at a rate of 90 kg per day and wean after 7-8 months, once they have reached about 15 m in length, and are able to follow the normal migration pattern alone. They reach sexual maturity at 5-10 years. This growth rate is astonishing and is probably the fastest in the animal kingdom.  From  conception to weaning, it represents a several billion-fold increase in tissue in just over a year and a half. Like other baleen whales, the blue whale has no teeth so it is hard to tell its age but scientists believe they live until at least 50.
Like other large whales, blue whales are threatened by chemical and sound pollution, habitat loss, overfishing of krill, ship strikes and becoming entangled in fishing gear. Climate change could also have a major impact on its food supply, since global warming and associated ocean acidification may impact krill populations. In addition, frontal zones - critical whale habitats - are projected to move further south due to climate change. Frontal zones are boundaries between different water masses, where water can rise from the depths, bringing with it large amounts of nutrients that stimulate the growth of phytoplankton and support substantial populations of prey species for whales. Blue whales would have to migrate further (perhaps 200-500 km more) to reach and feed at these food-rich areas where they build up reserves to sustain themselves for the rest of the year. These longer migration paths could increase the energy costs  of migration and reduce the duration of the main feeding season. As frontal zones move southward, they also move closer together, reducing the overall area of foraging habitat available.

According to the last paragraph, how does climate change affect the blue whale?

      Though the conservation movement had European roots, many observers maintain that the United States has emerged as the world's leader in environmentalism.
       The transcendentalism of the early 1800s and its celebration of the natural world arrived just in time to be trampled underfoot by the ravages of the Industrial Revolution. As forests disappeared under the ax of reckless timber barons, coal became a popular source of energy. Unfettered use of coal in homes and factories resulted in horrific air pollution in cities like London, Philadelphia, and Paris.
      In the 1850s, a carnival huckster named George Gale heard about an immense California redwood that was over 600 years old when Jesus was born. Upon seeing the magnificent tree, nicknamed The Mother of the Forest, Gale hired men to cut the tree down so that its bark could be displayed in his sideshow. The reaction to Gale's stunt, however, was swift and ugly: "To our mind, it seems a cruel idea, a perfect desecration, to cut down such a splendid tree ... what in the world could have possessed any mortal to embark in such a speculation with this mountain of wood?," wrote one editor.
       The growing realization that human industry was obliterating irreplaceable wilderness -- and endangering human health -- resulted in the earliest efforts at managing natural resources. In 1872, Yellowstone National Park was created, the first of what became one of America's best ideas: a network of national parks that were strictly off-limits to exploitation.

According to paragraph 3, what made George Gale want to destroy such a holy tree?

Body language is a vital form of communication. In fact, it is believed that the various forms of body language contribute about 70 percent to our comprehension. It is important to note, however, that body languages varies in different cultures. Take for example, eye movement. In the USA a child is expected to look directly at a parent or teacher who is scolding him/her. In other cultures the opposite is true. Looking directly at a teacher or parent in such a situation is considered a sign of disrespect.
Another form of body language that is used differently, depending on the culture, is distance. In North America people don’t generally stand as close to each other as in South America. Two North Americans who don’t know each other well will keep a distance of four feet between them, whereas South Americans in the same situation will stand two to three feet apart. North Americans will stand closer than two feet apart only if they are having a confidential conversation or if there is intimacy between them.
Gestures are often used to communicate. We point a finger, raise an eyebrow, wave an arm – or move any other part of the body - to show what we want to say. However, this does not mean that people all over the world use the same gestures to express the same meanings. Very often we find that the same gestures can communicate different meanings, depending on the country. An example of a gesture that could be misinterpreted is sticking out the tongue. In many cultures it is a sign of making a mistake, but in some places it communicates ridicule.
The dangers of misunderstanding one another are great. Obviously, it is not enough to learn the language of another culture. You must also learn its non-verbal signals if you want to communicate successfully.

As stated in the passage, in order to communicate successfully with people from another culture, it is advisable for a person     .

“Where is the university?” is a question many visitors to Cambridge ask, but no one can give them a clear answer, for there is no wall to be found around the university. The university is the city. You can find the classroom buildings, libraries, museums and offices of the university all over the city. And most of its members are the students and teachers or professors of the thirty-one colleges. Cambridge is already a developing town long before the first students and teachers arrived 800 years ago. It grew up by the river Granta, as the Cam was once called. A bridge was built over the river as early as 875.

In the fourteenth and fifteenth centuries, more and more land was used for college buildings. The town grew faster in the nineteenth century after the opening of the railway in 1845. Cambridge became a city in 1951 and now it has the population of over 100000. Many young students want to study at Cambridge. Thousands of people from all over the world come to visit the university town. It has become a famous place all around the world.

Why did people name Cambridge the “city of Cambridge”?

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:
Garbage cans are not magical portals. Trash does not disappear when you toss it in a can. Yet, the average American throws away an estimated 1,600 pounds of waste each year. If there are no magic garbage fairies, where does all that trash go? There are four methods to managing waste:
Recycling, landfilling, composting, and incinerating. Each method has its strengths and weaknesses. Let’s take a quick look at each.
Recycling is the process of turning waste into new materials. For example, used paper can be turned into paperboard, which can be used to make book covers. Recycling can reduce pollution,  save materials, and lower energy use. Yet, some argue that recycling wastes energy. They believe   that collecting, processing, and converti g waste uses more energy than it saves. Still, most people    agree that recycling is better for the planet
than landfilling.
Landfilling is the oldest method of managing waste. In its simplest form, landfilling is when people bury garbage in a hole. Over time the practice of landfilling has advanced. Garbage is compacted before it is thrown into the hole. In this way more garbage can fit in each landfill. Large liners are placed in the bottom of landfills so that toxic garbage juice doesn't get into the ground  water. Sadly, these liners don't always work. Landfills may pollute the local water supply. Not to mention that all of that garbage stinks. Nobody wants to live next to a landfill. This makes it hard to find new locations for landfills.
Compositing is when people pile up organic matter, such as food waste, and allow it to decompose. The product of this decomposition is compost. Compost can be added to  the soil  to  make the soil richer and better for growing crops. While composting is easy to do onsite somewhere, like home or school, it's hard to do after the garbage gets all mixed up. This is because plastic and other inorganic materials must be removed from the compost pile or they will pollute the  soil. There's a lot of plastic in garbage, which makes it hard to compost on a large scale.
One thing that is easier to do is burning garbage. There are two main ways to incinerate waste. The first is to create or harvest a fuel from the waste, such as methane gas, and burn the fuel. The second is to burn the waste directly. The heat from the incineration process can boil water,  which  can  power steam generators. Unfortunately, burning garbage pollutes the air. Also, some critics worry that incinerators destroy valuable resources that could be recycled.
Usually, the community in which you live manages waste. Once you put your garbage in that can, what happens to fit is beyond your control. But you can make choices while it is still in your possession. You can choose to recycle, you can choose to compost, or you can choose to let someone else deal with   it. The choice is yours.

According to the passage all of the following are mentioned as an issue with landfilling EXCEPT that

   We get great pleasure from reading. The more advanced a man is, the greater delight he will find in reading. The ordinary man may think that subjects like philosophy or science are very difficult and that if philosophers and scientists read these subjects, it is not for pleasure. But this is not true. The mathematician finds the same pleasure in his mathematics as the school boy in an adventure story. For both, it is a play of the imagination, a mental recreation and exercise.

   The pleasure derived from this activity is common to all kinds of reading. But different types of books give us different types of pleasure. First in order of popularity is novel-reading. Novels contain pictures of imaginary people in imaginary situations, and give us an opportunity of escaping into a new world very much like our world and yet different from it. Here we seem to live a new life, and the experience of this new life gives us a thrill of pleasure.

   Next in order of popularity are travel books, biographies and memoirs. These tell us tales of places we have not seen and of great men in whom we are interested. Some of these books are as wonderful as novels, and they have an added value that they are true. Such books give us knowledge, and we also find immense pleasure in knowing details of lands we have not seen and of great men we have only heard of.

   Reading is one of the greatest enjoyments of life. To book-lovers, nothing is more fascinating than a favorite book. And, the ordinary educated man who is interested and absorbed in his daily occupation wants to occasionally escape from his drudgery into the wonderland of books for recreation and refreshment.

According to paragraph 4, which of the following is the most fascinating to booklovers?

Social parasitism involves one species relying on another to raise its young. Among vertebrates, the best known social parasites are such birds as cuckoos and cowbirds; the female lays egg in a nest belonging to another species and leaves it for the host to rear
The dulotic species of ants, however, are the supreme social parasites. Consider, for example, the unusual behavior of ants belonging to the genus Polyergus. All species of this ant have lost the ability to care for themselves. The workers do not forage for food, feed their brood or queen, or even clean their own nest. To compensate for these deficits, Polyergus has become specialized at obtaining workers from the related genus Formica to do these chores
In a raid, several thousand Polyergus workers will travel up to 500 feet in search of a Formica nest, penetrate it, drive off the queen and her workers, capture the pupal brood, and transport it back to their nest. The captured brood is then reared by the resident Formica workers until the developing pupae emerge to add to the Formica population, which maintains the mixed- species nest. The Formica workers forage for food and give it to colony members of both species. They also remove wastes and excavate new chambers as the population increases
The true extent of the Polyergus and dependence on the Formica becomes apparent when the worker population grows too large for existing nest. Formica scouts locate a new nesting site, return to the mixed-species colony, and recruit additional Formica nest mates. During a period that may last seven days, the Formica workers carry to the new nest all the Polyergus eggs, larvae, and pupae, every Polyergus adult, and even the Polyergus queen
Of the approximately 8000 species of ants in the world, all 5 species of Polyergus and some 200 species in other genera have evolved some degree of parasitic relationship with other ants

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:
Where one stage of child development has been left out, or not sufficiently experienced, the child may have to go back and capture the experience of it. A good home makes this possible
- for example, by providing the opportunity for the child to play with a clockwork car or toy railway train up to any age if he still needs to do so. This principle, in fact, underlies all psychological treatment of children in difficulties with their development, and is the basic of work in child clinics.
The beginnings of discipline are in the nursery. Even the youngest baby is taught by gradual stages to wait for food, to sleep and wake at regular intervals and so on. If the child feels the world around him is a warm and friendly one, he slowly accepts its rhythm and accustoms himself to conforming to its demands. Learning to wait for things, particularly for food, is a very important element in upbringing, and is achieved successfully only if too great demands are not made before the child can understand them. Every parent watches eagerly the child's acquisition of each new skill: the first spoken words, the first independent steps, or the beginning of reading and writing. It is often tempting to hurry the child beyond his natural learning rate, but this can set up dangerous feelings of failure and states of anxiety in the child. This might happen at any stage. A baby might be forced to use a toilet too early, a young child might be encouraged to learn to read before he knows the meaning of the words he reads. On the other hand, though, if a child is left alone too much, or without any learning opportunities, he loses his natural zest for life and his desire to find out new things for himself.
Learning together is a fruitful source of relationship between children and parents. By playing together, parents learn more about their children and children learn more from their parents. Toys and games which both parents and children can share are an important means of achieving this co-operation. Building-block toys, jigsaw puzzles and crosswords are good examples.
Parents vary greatly in their degree of strictness or indulgence towards their children. Some may be especially strict in money matters; others are severe over times of coming home at night, punctuality for meals or personal cleanliness. In general, the controls imposed represent the needs of the parents and the values of the community as much as the child's own happiness and well-being.
With regard to the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality. Also, parents should realize that“Example is better than precept”. If they are hypocritical and do not practice what they preach, their children may grow confused and emotionally insecure when they grow old enough to think for themselves, and realize they have been, to some extent, deceived. A sudden awareness of a marked difference between their parents' ethics and their morals can be a dangerous disillusion.

If you could travel back in time five centuries, you'd encounter a thriving Aztec empire in Central Mexico, a freshly painted "Mona Lisa" in Renaissance Europe and cooler temperatures across the Northern Hemisphere. This was a world in the midst of the Little Ice Age (A.D. 1300 to   1850) and a period of vast European exploration now known as  the Age of  Discovery. But what if  we could look 500 years into the future and glimpse the Earth of the 26th century? Would the  world seem as different to us as the 21st century would have seemed to residents of the 16th century? For starters, what will the weather be like?
Depending on whom you ask, the 26th century will either be a little chilly or infernally hot.
Some solar output models suggest that by the 2500s, Earth's climate will have cooled back down to near Little Ice Age  conditions. Other studies predict that ongoing climate change and fossil fuel use will render much of the planet too hot for human life by 2300.
Some experts date the beginning of human climate change back to the Industrial Revolution  in the 1800s, others to slash-and-burn agricultural practices in prehistoric times. Either way, tool- wielding humans alter their environment -- and our 26th century tools might be quite impressive indeed.
Theoretical physicist and futurist Michio Kaku predicts that in a mere 100 years, humanity will make the leap from a type zero civilization to a type I civilization on the Kardashev Scale. In  other words, we'll become a species that can harness the entire sum of a planet's energy. Wielding such power, 26th-century humans will be masters of clean energy technologies such as fusion and solar power. Furthermore, they'll be able to manipulate planetary energy in order to control global climate. Physicist Freeman Dyson, on the other hand, estimates the leap to a type I civilization would occur within roughly 200 years.
Technology has improved exponentially since the 1500s, and this pace will likely continue in   the centuries to come. Physicist Stephen Hawking proposes that by the  year 2600, this growth  would see 10 new theoretical physics papers published every 10  seconds. If  Moore's Law holds  true and both computer speed and complexity double every 18 months, then some of  these  studies may be the work of highly intelligent machines.
What other technologies will shape the world of the 26th century? Futurist and author Adrian Berry believes the average human life span will reach 140 years and that the digital  storage of human personalities will enable a kind of computerized immortality. Humans will farm the oceans, travel in starships and reside in both lunar and Martian colonies while robots explore the outer cosmos.

In the explosion of the linguistic life cycle, it is apparent that it is much more difficult to learn a second language in adulthood than a first language in childhood. Most adults never completely master a foreign language, especially in Phonology – hence the ubiquitous foreign accent. Their development often “fossilizes” into permanent error patterns that no teaching or correction can undo. Of course, there are great individual differences, which depend on effort, attitudes, amount of exposure, quality of teaching and plain talent, but there seems to be a cap for the best adults in the best circumstances
Many explanations have been advanced for children’s superiority; they exploit Motherese (the simplified, repetitive conversation between parents and children), make errors unself- consciously, are more motivated to communicate, like to conform, are not set in their ways, and have not first language to interfere. But some of these accounts are unlikely, based on what is known about how language acquisition works. Recent evidence is calling these social and motivation explanations into doubt. Holding every other factor constant, a key factor stands out: sheer age
Systematic evidence comes from the psychologist Elissa Newport and her colleagues. They tested Korean and Chinese – born students at the University of Illinois who had spent a least ten years in the United States. The immigrants were give a list of 276 simple English sentences, half of them containing some grammatical error. The immigrants who came to the United States between the age of 3 and 7 performed identically to American – born students. Those who arrived between ages 8 and 15 did worse the latter they arrived, and those who arrived between 17 and 39 did the worst of all, and showed huge variability unrelated to their age of arrival.

Do you think you're smarter than your parents and grandparents? According to James Flynn, a professor at a New Zealand university, you are! Over the course of the last century, people who have taken IQ tests have gotten increasingly better scores-on average, three points better for every decade that has passed. This improvement is known as "the Flynn effect," and scientists want to know what is behind it.
IQ tests and other similar tests are designed to measure general intelligence rather than knowledge. Flynn knew that intelligence is partly inherited from our parents and partly the result of our environment and experiences, but the improvement in test scores was happening too quickly to be explained by heredity. So what was happening in the 20th century that was helping people achieve higher scores on intelligence tests?
Scientists have proposed several explanations for the Flynn effect. Some suggest that the improved test scores simply reflect an increased exposure to tests in general. Because we take so many tests, we learn test-taking techniques that help us perform better on any test. Others have pointed to better nutrition since it results in babies being born larger, healthier, and with more brain development than in the past. Another possible explanation is a change in educational styles, with teachers encouraging children to learn by discovering things for themselves rather than just memorizing information. This could prepare people to do the kind of problem solving that intelligence tests require.
Flynn limited the possible explanations when he looked carefully at the test data and discovered that the improvement in scores was only on certain parts of the IQ test. Test takers didn't do better on the arithmetic or vocabulary sections of the test; they did better on sections that required a special kind of reasoning and problem solving. For example, one part of the test shows a set of abstract shapes, and test-takers must look for patterns and connections between them and decide which shape should be added to the set.
According to Flynn, this visual intelligence improves as the amount of technology in our lives increases. Every time you play a computer game or figure out how to program a new cell phone, you are exercising exactly the kind of thinking and problem solving that helps you do well on one kind of intelligence test. So are you really smarter than your parents? In one very specific way, you may be.a
