Paragraph Ten

    Bats emit a very high frequency sound and listen for the echo that bounces off objects. The difference in time between emitting the sound and hearing the echo allows the bat to build up a mental “picture” of its environment. Homing pigeons can fly back to their home lofts by using the Earth’s magnetic field to navigate.

The animals with s___powers.

Since their first appearance on earth, men have gathered information and have attempted to pass useful ideas to other men. 46.The carving of word-pictures on the walls of ancient caves as well as hieroglyphics on stone tablets represent some of men's earliest efforts to convey information.Scenes of hunting, maps of battles, and the stories of heroes were put down for all to see.

But as civilizations grew more complex, better methods of communication were needed. The written word, carrier pigeons, the telegraph, andmany other devices carried ideas faster and faster from man to man. 47.In recent years one type of machine, the electronic computer, has become increasingly important in the lives of all the people in the industrialized nations of the world.Computers are now widely used aids for communication, calculation, and other activities. Their effect becomes more important every day.

Man has always been interested in extending the range of his senses and the power of his mind. Through the years, he has invented many instruments to help him see better and understand more. 48.The telescope, for example, was invented to allow him to look at faraway objects. To see the very small things in the world, the microscope was developed.Radio, telephone, and telegraph are means by which man has extended the range of his senses of hearing and speech.

While developing his power of thought, man first began to identify and count objects. He began to ask the questions “What is it?” and “How many?”. It was a long time ago that this numbering and comparing of things began.

49.New ways of helping with counting and recording information evolved. Marks of different kinds were taken to represent certain quantities, and other marks were taken to represent relationships between quantities.

New devices to aid in the manipulation of numbers were developed.

Electronic computers are among the fastest and most useful instruments for sorting and comparing in use today. 50.Computers provide the means for greater speed and accuracy in working with ideas than had previously been possible. With the development of these new tools, it is as if man has suddenly become a millionaire of the mind.

Although man has been growing mentally richer ever since he started to think, the electronic computer allows and will continue to allow him to perform tremendous “mental” tasks in a relatively short time. Great scientists of the past produced ideas which were the basis for great advances, but their ideas sometimes had to wait for years before they were understood sufficiently well to be of practical use. With the computer, the ideas of today’s scientists can be studied, tested, distributed, and used more rapidly than ever before.

51.Old lines and methods of communication do not work easily or efficiently with as much information as we have now. The repeated actions of preparing， sorting, filling, distributing, and keeping track of records and publications can be as troublesome as calculating. Errors occur because men grow tired and can be distracted.

The basic job of computers is the processing of information. For this reason computers can be defined as devices which accept information, perform mathematical or logical operations with the information, and then supply the results of these operations as new information.

Paragraph Nine

    Some air pollutants can cause cancer, problems with having children and other very serious illnesses as well as environmental damage. Air pollutants have killed people swiftly when large quantities were released; the 1984 release of methyl isocyanate at a pesticide-manufacturing plant in Bhopal, India, killed approximately 4,000 people and injured more than 200,000.

Air pollutants can be f__.

Paragraph Eight

   Studies have shown that people forced to share workspaces reported feeling marginalized, experienced more distractions, negative relationships and uncooperative behavior, not to mention feeling like their supervisors were being less supportive. Studies also find that open plan offices can have some negative psychological effects, reducing employee satisfaction, focus, and their feelings of having privacy at work.

Open office e___and its negative effects.

Paragraph Seven

Spinach may cause Alzheimer’s disease in at-risk people, research suggests. The salad leaf’s iron-rich content may damage the brain similar to how the compound causes metal to rust, according to the researchers. People with high levels of iron, which has previously been associated with Alzheimer’s, are more likely to experience rapid cognitive decline, a study found.

Iron-rich v   may lead to Alzheimer’s disease.

Paragraph Six

    Driving for more than two hours a day negatively affects IQ levels, scientists have warned. In what might come as unwelcome news for middle-aged commuters, a recent study found that long periods behind the wheel could speed up the effects of age on the brain because the mind is less active on long car journeys.

Driving for a long t   may dull your mind.

Paragraph Five

    Economists long ago point out why it is bad for a single firm to dominate a market. They believe that monopolists can set prices almost asthey please. Worse, if a company has no fear of competition, it needn’t worry too much about keeping customers happy and creating new and better products.

The c____of monopoly.

Paragraph Four

  Recent research suggests that tea-producing areas in some places, notably East Africa, could decline by as much as 55 percent by 2050 as temperatures change. Tea pickers are also feeling the impacts of climate change. During harvest season, increased air temperatures are creating an increased risk of heatstroke for field workers.

The effect of r   temperatures on tea production.

Paragraph One

When you lose an hour of sleep, it decreases your well-being, productivity, health, and ability to think the following day. One of the most influential studies of human performance found that top performers slept 8 hours and 36 minutes per day. You are simply a different person when you operate on insufficient sleep.

Insufficient sleep may lead to p   performance.

Paragraph Two

   Type D personalities usually have a low self-esteem and a great fear of disapproval. Negative emotions such as worrying, stress, depression and anger visit type D personalities more often. A small event that is usually overlooked by others can bother a type D a lot and even ruin his mood.

A c___type and its features.

Paragraph Three

    Industry needs automobiles for farming as well as transportation. Everyday, automobiles drive people to and from work. On weekends automobiles take families for joyful outings. And during holiday seasons, automobiles fill the highways everywhere, even in remote areas. It could be said that the wheels of automobiles move society forward.

The w____use of automobiles.

In the laboratories where astronauts are trained for their journeys, they are subjected to conditions that resemble those of flight. It takes time for them to prepare for the great changes that occur in space. When the spaceship leaves the earth at tremendous speed, the astronauts feel as if they are being crushed against the spaceship floor. Later, when they leave the zone of the earth’s gravitation, they are unable to stay in one place. Simple actions, such as eating and drinking, become very difficult to perform. You may get an inkling of whatthe astronauts have to deal with if you try to drink a glass of water while standing on your head or while just lying down.

The beginnings of man’s conquest of space took place in 1958, seven years before Leonov’s trip. The first successful launching of “Sputnik” demonstrated that it was indeed possible to send objects far enough out of range of earth’s gravity so that they would not fall back to earth. Rather, such objects could be forced to revolve about the earth, just as the moon does. However, while the moon is so far from earth that it takes it a month to revolve around the earth, man-made satellites, which are closer to earth, can make a complete revolution in a few hours.

It was three years after the first satellite launching that a spaceship containing a man made a successful flight. The flight lasted less than two hours, but it pointed the way to future developments.

Other planets are so far away that spaceships must attain tremendous speeds to reach them in a reasonable time. If spaceships were launched from space or from the moon, the absence of weight would permit theships to be launched with great speed at reduced pressures. A relatively small explosion would be enough to send a ship off at a very fast rate. And, since there is no atmosphere in space as there is on earth, the spaceship would meet with no resistance

What can we learn from Paragraph 4?

What is the current status of wearables?

According to Paragraph 2, Apple Watch cannot be used to___.

The underlined part in Paragraph 1 means___.

Passage Four

“In the beginning was Apple. All things were made by it; and without it was not anything made that was made.55 If technophiles were to write their own Testament, these might be the opening lines. Apple’s ability to redefine the appeal of whole categories of computing has attracted the unerring faith of millions of followers. Apple has popularized existing technologies four times: with the Macintosh computer in 1984, the iPod in 2001, the iPhone in 2007 and the iPad in 2010. Recently the faithful have prayed that Apple will pull it off again with its smartwatch. Many firms already make wrist-based devices that measure sleep patterns and exercise, but so far the category has remained a niche plaything for geeks and athletes.

On March 9th the firm gathered its flock to share details about the Apple Watch, which will go on sale next month. Tim Cook, its boss, called it “the most advanced timepiece ever created”. In addition to telling the time, it can respond to voice commands, measure its wearer’s heart rate, act like a credit card at payment points and provide alerts for incoming calls and e-mails. It can display many of the apps that are popular on smartphones, such as those of social networks, without the hassle of having to pull out a phone.

The launch of the Apple Watch points to a broader story: high expectations that wearable technology will soon take off. Some 21m wearable devices were sold last year, according to IDC, a research firm; wrist-worn wearables, including watches, were the majority.

Wearables have so far lacked the elegant design and ease of use that helped smartphones ring in such success. Even the fashion models who were hired to demonstrate Google Glass struggled to make it look stylish. Most companies are focusing on the engineering challenges in front of them and paying too little attention to the “cultural engineering” that needs to happen for wearables to become accepted. Apple has hired fashion-conscious executives from luxury brands like Burberry and Yves Saint Laurent to make its watch attractive, but it is not yet obvious that it has cracked the cool code.

But the biggest challenge facing wearables is the absence to date of a “killer app”. Watches do not yet provide much more than smartphones currently do, and some models offer far less. Moving beyond phones’capabilities will take time. It will also depend on getting developers to build apps that will make the most of wearables, possibilities.

Passage Two

I’ve known the mother sitting in front of me at this parent-teacher conference for years, and we have been through a lot together. I have taught three of her children, and I like to think we’ve even become friends during our time together. She’s a conscientious mother who obviously loves her children with all of her heart. Tve always been honest with her about their strengths and weaknesses, and I think she trusts me to tell her the truth. But when she hits me with the concern that’s been bothering her for a while, all I can do is nod, and stall for time.

“Marianna’s grades are fine; I’m not worried about that, but she just doesn’t seem to love learning anymore.” She’s absolutely right. I’d noticed the same thing about her daughter over the previous two or three years, and I have an answer, right there on the tip of my tongue, for what has gone wrong.

The truth—for this parent and so many others—is this: Her child has sacrificed her natural curiosity and love of learning at the altar of achievement, and it’s our fault. Marianna’s parents, her teachers, society at large—we are all implicated in this crime against learning. From her first day of school, we pointed her toward that altar and trained her to measure her progress by means of points, scores, and awards. We taught Marianna that her potential is tied to her intellect,and that her intellect is more important than her character. We taught her to come home proudly bearing As, championship trophies, and college acceptances, and we inadvertently taught her that we don’t really care how she obtains them. We taught her to protect her academic and extracurricular perfection at all costs and that it’s better to quit when things get challenging rather than risk marring that perfect record. Above all else, we taught her to fear failure. That fear is what has destroyed her love of learning.

Marianna is very smart and high-achieving, and her mother reminds her of that on a daily basis. However, Marianna does not get praised for the diligence and effort she puts into sticking with a hard math problem or a convoluted scientific inquiry. If that answer at the end of the page is wrong, or if she arrives at a dead end in her research, she has failed—no matter what she has learned from her struggle. And contrary to what she may believe, in these more difficult situations she is learning. She leams to be creative in her problem-solving. She leams diligence. She leams self-control and perseverance. But because she is scared to death of failing, she has started to take fewer intellectual risks.

Questions 6-10 are based on Passage Two.

Marianna’s mother_____.

We can learn from Paragraph 2 that____.

The word “teetotaler” in Paragraph 2 means____.

The passage tells us that__.

Canned foods do not necessarily mean unhealthy because they may contain

Passage One

Many people believe that taking vitamin supplements is the best safeguard against the dangers of an incomplete diet, but this should be a last resort rather than a way out of a problem. Even if there is a genuine need for extra vitamins, then sooner or later the question arises “which ones do I need，how much of them, and how often?” There is really no simple answer to this question. The Food Standards Committee suggests in their recent report to the government that we do not need any extra vitamins. They say that they are “not necessary for a healthy individual eating a normal diet”. Whilst few of us would challenge their authority on the subject of nutrition, it is, perhaps, pertinent to ask the question “how many of us are healthy, and what is a normal diet?” There is an element of doubt in many minds about these two aspects and though few people are familiar with the wording of the Food Standards Report they do wonder instinctively if they areeating the right things. The blame for faulty eating habits is often placed at the door of the ubiquitous junk and convenience foods. As we have seen, some of these are not the criminals they are made out to be. White bread is only slightly less nutritious than brown bread and frozen vegetables can be almost as “fresh” as fresh food. There are very few foods which can really be described as pure rubbish. Many pre-packed foods contain too much sugar and we would all benefit by avoiding these, but most tinned, processed and dried foods contain useful amounts of fat, protein, carbohydrate, vitamins and minerals. The addition of a small amount of fruit or a side salad to convenience foods such as pizzas or hamburgers can turn a snack into a well-balanced meal.

“Junk” food is difficult to define. White sugar is probably the nearest contender for the title. It contains plenty of calories for energy but not much else, and is often described as an “empty calorie” food. Alcohol is also high in calories, but beer and wine contain some of the B vitamins and wine is a good source of iron, so even a teetotaler could not describe all alcohol as useless, nutritionally speaking. Calories measure the energy we derive from the food we eat, and sugar and alcohol are sometimes described as having a high energy density. There is a limit to the amount of energy we need each day (2,000～2,200 calories is the average for women and 2,500-3,000 for men) and if we eat too much sugar and alcohol there is no appetite left for the vitamin-rich foods we need—fish, meat, fruit and vegetables. Buying vitamins can be predicted by psychological as well as nutritional motives and it is prudent to investigate why we think we need them and what benefits we expect from them before we rush off to the health shop to make our purchases.
