If you travel by air across the center of Africa or South America, you fly over forests for thousands of kilometers. These great forests are the oceans of trees. There are thousands and thousands of different kinds of plants and animals. However, the world's forests are getting smaller all the time. We are cutting down the trees because we need wood, and we need more farmland. Some people say that there will not be any forests like these in 20 or 30 years. What will happen if they disappear? If we cut down our forests, a lot of plants and animals will disappear from the world. In a lot of places the new farmland will soon look like the old deserts. Crops will not grow there. It will not rain very often, and the weather will get very hot. Perhaps the climate of the world will change. This will be dangerous for everyone in the world. That is why we must take care of our forests.

Human memory can be very difficult to understand. We find its limitations every day, when we forget a friend’s telephone number, the name of a business contact or the title of a favorite book. People have developed a variety of strategies for combating forgetfulness-messages written on Post-it notes, for example, or electronic address books carried in handheld devices-but important information continues to slip through the cracks. Recently, however, new systems may allow people to record everything they see and hear-and even things they cannot sense-and to store all these data in a personal digital archive that is both searchable and secure.

Digital memories can do more than simply assist the recollection of past events, conversations and projects. Portable sensors can take readings of things that are not even perceived by humans, such as oxygen levels in the blood or the amount of carbon dioxide in the air. Computers can then scan these data to identify patterns: for instance, they might determine which environmental conditions worsen a child’s asthma. Sensors can also log the three billion or so heartbeats in a person’s lifetime, along with other physiological indicators, and warn of a possible heart attack. This information would allow doctors to spot irregularities early, providing warnings before an illness becomes serious. Your physician would have access to a detailed, ongoing health record, and you would no longer have to rack your brain to answer questions such as “When did you first feel this way?” A Microsoft research project, called

My Life Bits, has provided some of the tools needed to compile a lifelong digital archive. They have found that digital memories

allow one to vividly relive an event with sounds and images. Every word one has ever read, whether in an e-mail, an electronic document or on a Web site, can be found again with just a few keystrokes.

Computers can analyze digital memories to help with time management, pointing out when you are not spending enough time on your highest

priorities. Perhaps most important, digital memories can enable all people to tell their life stories to their later generation in a systematic and detailed fashion that until now has been reserved solely for the rich and famous.

Dieting to lose weight has become very popular in recent years. People have become more health conscious and try to take better care of their bodies by eating more nutritiously （有营养） and exercising more regularly to lose any unnecessary fat that they may have. Not only are people being more careful about what they eat, they are also concerned with how they eat and how their meals are prepared. People are taking more time for each meal. Many avoid the so-called " plastic " fast-food hamburgers and choose to eat a salad or a sandwich of more healthful ingredients （成分） in a quiet restaurant with a more leisurely atmosphere. At home, they also try to take enough time to eat a relaxed dinner without phone or TV interruptions. While dieting may be viewed as beneficial, it has also become a serious problem for Americans, particularly for young women. Dieting for them has actually become a psychological addiction （依赖）. They eat so little that they can lose as much as fifty percent of their total body weight, and although they look like skeletons, they still insist that they are fat. The current wave of exercising, dieting and the problems produced have caused many organizations to begin educating the public. Many schools, hospitals, health organizations, newspapers and magazines, for example, are offering classes, printing booklet articles, etc. to inform the public of the way to

exercise and diet, of the

dangers of dieting too rapidly, and of the places people can go for medical help if they find themselves on the road to "diet addiction". 答案

问题 19 需要评分

What must you do when you receive a present for your birthday? You

have to sit down and write a thank-you note. The words "Thank you" are very important. We

have to use them on so many occasions. We say them when someone gives us a drink, helps us to pick up things, hands us a letter, lends us a book or gives us a gift. Another important word is "please". Many people forget to use it. It is rude to ask

someone to do something without saying "please". We have to use it when we ask for something, too. It may be a book or a pencil, more rice or more sauce, help or advice. It may be in the classroom, at home, at the bus-stop or over the counter. We have to use "please" to make our request pleasant. We have to learn to say "sorry" too. When we have hurt someone's feeling, we will have to go up and say we are sorry. When we have told a lie and feel sorry, we will have to use the same word. When we have forgotten something or broken a promise, we will have to explain with that word, too. "Sorry" is a healing word. We can make people forget wrongs by

using it sincerely. These three words are simple but important. They are pleasing words to use in any language. 答案

问题 25 需要评分

The word "horsepower" was first used two hundred years ago. James Watt had made the world's first widely used steam engine. He had no way of telling people exactly how powerful it was, for at that time there were no units for measuring power. Watt decided to find out how much work one strong horse could do in one minute. He called that unit one horsepower. With this unit he could measure the work his steam engine could do. He discovered that a horse could lift a 3300-pound weight 10 feet into the air on one minute. His engine could lift a 33-pound weight 100 feet in one minute. Because his engine did ten times as much work as the horse, Watt called it a ten horsepower engine. 答案

Paper is one of the most important products ever invented by man.

Wide spread use of written language would not have been possible without some cheap and practical material to write on. The invention of paper meant that more people could be educated because more books could be printed and distributed. Together with the printing press, paper provided an extremely important way to communicate knowledge.

How much paper do you use every year? Probably you cannot answer that question quickly. In 1900 the world's use of paper was about one kilogram for each person a year. Now some countries use as much as

50 kilograms of paper for each person a year. Countries like the

United States, England and Sweden use more paper than other countries. Paper, like many other things that we use today, was first made in China. In Egypt and the West, paper was not very commonly used before the year 1400. The Egyptians wrote on a kind of material made of a water plant. Europeans used parchment for many hun?dreds of years. Parchment was very strong; it was made from the skin of certain young ani?mals. We have learnt of the most important facts of European history from records that were kept on parchment. (208

What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result of where and how you live? These are very old questions and the answers to them are still not clear. We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle. It needs exercise.

Mental exercise is particularly important for young children. Many child psychologists (心理学家) think that parents should play with their children more often and give them problems to think about. The children are then more likely to grow up bright and intelligent. If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent. Parents should also be careful with what they say to young children.

According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive things to their children, such as "That was a very clever thing you did." or "You are such a smart child."

Global Warming Global warming may or may not be the great environmental crisis of the 21st century, but —regardless of whether it is or isn’t —we won’t do much about it. We will argue over it and may even, as a nation, make some fairly solemn- sounding commitments to avoid it. But the more dramatic and meaningful these commitments seem, the less likely they are to be observed. A1 Gore calls global warming an “inconvenient truth”, as if merely recognizing it could put us on a path to a solution. But the real truth is that we don’t know enough to relieve g lobal warming, and — without major technological breakthroughs —we can’t do much about it. From 2003 to 2050, the world’s population is predicted to grow from 6.4 billion to 9.1 billion, a 42% increase. If energy use per person and technology remain the same, total energy use and greenhouse gas emissions (mainly, CO2) will be 42% higher in 2050.But that’s too low, because societies that grow richer use more energy.

We need economic growth unless we leave the world’s poor to their present poverty and freeze everyone else’s living standards. With modest growth, energy use and greenhouse emissions will more than double by 2050. No government will adopt strict restrictions on economic growth and personal freedom (limits on electricity usage, driving and travel) that might cut back global warming. Still,

politicians want to show they’re “doing something” Consider the Kyoto Protocol. It allowed

countries that joined to punish those that didn’t. But it hasn’t reduced CO2 emissions (up about 25% since 1990), and man y signatories didn’t adopt tough enough policies to hit their 2008-2012 targets. The practical conclusion is that if global warming is a potential disaster, the only solution is new technology. Only an aggressive research and development program might find ways of breaking our dependence on fossil

fuels or dealing with it. The trouble with the global warming debate is that it has become a moral problem when it’s really an engineering one. The inconvenient truth is that if we don’t solve the engineering prob lem, we’re helpless. 答案
