As kids, our grandparents frequently scared us by talking about how difficult life was when they were growing up. They mentioned walking miles to school in the snow, or doing hours of manual labour for little pay. Life has changed greatly since then, and it seems to get easier year by year. In fact, with the help of robots we soon might have to do much at all. But is this a good thing?
By 2030, it’s estimated that robotics will be a $10 billion business worldwide. Companies are already starting to integrate them into the workforce. The electronics manufacturer Foxconn is drawing up plans to launch a factory within the next 10 years that’s completely staffed by robot workers. Meanwhile, an American company Briggo has invented a robot that serves gourmet- quality coffee to customers. With the push of a button it will crush coffee beans, measure exact quantities of water, and even wave a steam wand to ensure customers get the perfect cream on top. Unlike human baristas, it can serve multiple drinks at once and work all day and night without a break.
Robots are also invading our homes. The Rooma is a mini-robot that vacuums rooms automatically according to a schedule. The Robomow is a device that will cut the grass for you while you sit in the shade. Then there’s the Nanda clocky, an alarm clock that makes sure that even the deepest sleepers get up on time. The clock is attached to a pair of wheels, and it will randomly move around the room. Once you finally catch it, you’re probably too awake to hit the snooze button. Although these early home robots are somewhat basic, they will likely become more capable as times goes on.
Although robots certainly help us to eliminate tedious tasks, many people are concerned about a future filled with robots. Some fear that humanity will start to decline if machines do everything for us. Others have even warned about the robot rebellion, in which robots become so smart that they may decide to turn on their masters. These ideas may seem a bit far-fetched, but there are certainly lots of questions that need to be answered before everyone opens up to the idea of a robotic future.

Which of the following is NOT true about the concerns over roboties?

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.

      Centuries ago, man discovered that removing moisture from food helped to preserve it, and that the easiest way to do this was to expose the food to sun and wind. In this way the North American Indians produced pemmican (dried meat ground into powder and made into cakes), the Scandinavians made stockfish and the Arabs dried dates and apricots.

      All foods contain water - cabbage and other leaf vegetables contain as much as 93% water, potatoes and other root vegetables 80%, lean meat 75% and fish anything from 80% to 60% depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is checked.

      Fruit is sun-dried in Asia Minor, Greece, Spain and other Mediterranean countries, and also in California, South Africa and Australia. The methods used vary, but in general the fruit is spread out on trays in drying yards in the hot sun. In order to prevent darkening, pears, peaches and apricots are exposed to the fumes of burning sulphur before drying. Plums for making prunes, and certain varieties of grapes for making raisins and currants, are dipped in an alkaline solution in order to crack the skins of the fruit slightly and remove their wax coating, so increasing the rate of drying.

      Nowadays most foods are dried mechanically; the conventional method of such dehydration is to put food in chambers through which hot air is blown at temperatures of about 110oC at entry to about 45oC at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.

      Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated horizontal steel cylinder or by spraying them into a chamber through which a current of hot air passes. In the first case, the dried material is scraped off the roller as a thin film which is then broken up into small, though still relatively coarse flakes. In the second process it falls to the bottom of the chamber as a fine powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients are dried separately and then mixed.

      Dried foods take up less room and weigh less than the same food packed in cans or frozen, and they do not need to be stored in special conditions. For these reasons they are invaluable to climbers, explorers and soldiers in battle, who have little storage space. They are also popular with housewives because it takes so little time to cook them.

Nowadays the common method for drying vegetables and minced meat is ______.

Ostriches are the largest and heaviest birds on earth. They can grow to be as tall as 9 feet and can weigh as much as 250 pounds. Even though they have wings, they cannot fly. Instead, ostriches have long, powerful legs that help them to run very fast when they feel threatened. Ostriches use their wings to move themselves forward and to help them change direction. Ostriches are native to Africa, where they still live in desert areas and dry, open grasslands called savannah. Ostriches can also be found in zoos all over the world. Humans have domesticated ostriches, so now ostriches live on farms in over a dozen countries, including the United States, China, India, Japan, Brazil and Costa Rica. They are raised for their meat, skin, and feathers. Ostriches like to live in small groups called herds. The male ostrich is called a rooster; the female, a hen. Baby ostriches are called chicks. The female ostrich lays the eggs, but both the male and the female take turns sitting on the eggs to keep them warm.

It’s a sound you will probably never hear, a sickened tree sending out a distress signal. But a group of scientists has heard the cries, and they think some insects also hear the trees and are drawn to them like vulture to a dying animal. Researchers with the US Department of Agriculture’s Forest Service fastened sensors to the bark of drought-stricken trees clearly heard distress calls. According to one of the scientists, most parched trees transmit their plight in the 50-hertz to 50-kilohertz range. (The unaided human ear can detect no more than 20 kilohertz). Red oak, maple, white pine, and birch all make slightly different sounds in the form of vibrations at the surface of the wood.
The scientists think that the vibrations are created when the water columns inside tubes that run along the length of the tree break, a result of too little water following through them. These fractured columns send out distinctive vibration pattems. Because some insects communicate at ultrasonic frequencies, they may pick up the trees' vibration and attack the weakened trees. Researchers are now running tests with potted trees that have been deprived of water to see if the sound is what attracts the insects. “Water-stressed trees also smell differently from other trees, and they experience thermal changes, so insects could be responding to something other than sound”, one scientist said.

Carnivorous plants feature one of several types of ―traps‖ to ensnare prey, which they consume to make up for nutrients that may be missing from the soil. While there are over 400 species of carnivorous plants in the world today, some are more (38)_____ than others. The most well-known of these plants are the snap traps, which include the Venus flytrap. Snap traps are easily identified by their leaves, which are separated into two lobes that have the ability to fold together. Inside the lobes, the surface is covered with tiny hairs that are (39) _____ to movement. When the plant‘s prey brushes against the hairs, it triggers a closing mechanism that rapidly brings the two lobes together, trapping the prey (40)_____ inside.

Millions of people are using cell phones today. In many places, it is actually considered unusual not to use one. In many countries, cell phones are very popular with young people. They find that the phones are more than a means of communication - having a mobile phone shows that they are cool and connected.

The explosion in mobile phone use around the world has made some health professionals worried. Some doctors are concerned that in the future many people may suffer health problems from the use of mobile phones. In England, there has been a serious debate about this issue. Mobile phone companies are worried about the negative publicity of such ideas. They say that there is no proof that mobile phones are bad for your health.

On the other hand, medical studies have shown changes in the brain cells of some people who use mobile phones. Signs of change in the tissues of the brain and head can be detected with modern scanning equipment. In one case, a travelling salesman had to retire at young age because of serious memory loss. He couldn't remember even simple tasks. He would often forget the name of his own son. This man used to talk on his mobile phone for about six hours a day every day of his working week, for a couple of years. His family doctor blamed his mobile phone use, but his employer's doctor didn't agree.

What is it that makes mobile phones potentially harmful? The answer is radiation. High-tech machines can detect very small amounts of radiation from mobile phones. Mobile phone companies agree that there is some radiation, but they say the amount is too small to worry about.

As the discussion about their safety continues, it appears that it’s best to use mobile phones less often. Use your regular phone if you want to talk for a long time. Use your mobile phone only when you really need it. Mobile phones can be very useful and convenient, especially in emergencies. In the future, mobile phones may have a warning label that says they are bad for your health. So for now, it's wise not to use your mobile phone too often

Facebook is a for-profit online social media and social networking service. The Facebook website was launched on February 4th, 2004 by Mark Zuckerberg, along with fellow Harvard College students and roommates. Since 2006, anyone age 13 and older has been allowed to become a registered user of Facebook though variations exist in minimum age requirement, depending on applicable local laws.

I log on to Facebook everyday to chat to my friends real friends and loads of online friends. Sometimes I have ten conversations going at the same time. I upload photos and update my Facebook profile all the time. But recently I’ve started to feel worried if I am offline for more than a few hours.

But I’ll try not to spend so much time on it in the future.

When naming a child, some parents seem to choose a name based simply on their personal preference. In other families, grandparents or professional name-makers come up with a child's name. In some cases, the time of a child's birth influences how the child's name is determined. In many European cultures, names are typically chosen by parents. Parents' choice for their child's name may be based on names of their relatives or ancestors. For example, in Italy, children are traditionally named after their grandparents. The parents generally use the father's parents' names first. If they have more children, then they will use the mother's parents' names. Similarly, some people in Eastern Europe name their children after relatives who have died. This tradition is seen as a means to protect the child from the Angel of Death. Traditionally in some Asian countries, a child's grandfather or a fortune-teller chooses the child's name. In contrast to the tradition of naming children after relatives, the child's name is chosen to influence the child's character. For example, names may be based on a connection to certain elements such as fire, water, earth, wood, or metal. Or the name might include a written character meaning beauty, strength, or kindness. In certain African cultures, when a child is born plays a large part in determining the child's name. In Ghana's Akan culture, the day a child is born determines the child's name. But each day has different names for boys and girls. For instance, a boy born on Friday is named Kofi, whereas a girl born on the same day is named Afua. Both Kofi and Afua mean "wanderer" or "explorer." Children with these names are seen as travelers. No matter where the name comes from, a child's name is the first gift in life. Whether the name is chosen according to preference or dictated by tradition, it reflects something about a child's culture. For that reason, all names should be treasured and respected.
