country as well. Whether or not solar energy can save your money depends on many things. Where you
live is one factor and the type of home you have is another. Things like insulation (绝缘材料), present
energy costs, and the type of system you buy are added factors.
Using solar energy can help save our precious fuel. As you know, our supplies of oil and gas are very
limited. There is just not enough on hand to meet all our future energy needs. Sooner or later Mother Nature
will say that"s all. The only way we can delay hearing those words is by starting to save energy now and
by using other sources, like the sun.
We won"t have to worry about the sun"s running out of energy for another several billion years or so.
Besides, the sun doesn"t offer as many problems as other energy sources. For example, fossil fuel (矿物
燃料) adds to already high pollution levels. With solar energy, we will still need sources of energy, but we
won"t need as much. That means we can cut down on our pollution problems. With all these good points,
why don"t we use more solar power? There are many reasons for this. The biggest reason is money. Until
now, it was just not practical for a home owner to put in a solar unit. There were cheaper sources of energy.
All that is changing now. Solar costs are starting to equal the costs of oil and electricity. Experts say
that gas, oil and electricity prices will continue to rise. The demand for electricity is increasing rapidly. But
new power plants will use more gas, oil or coal. Already in some places the supply of electricity is being
rationed (限量供应). Solar energy is now in its infancy (初期). It could soon grow to become a major part
of our nation"s energy supply.
B. Solar energy.
C. Energy and pollution.
D. Energy and money.
B. become home owners
C. get rid of present energy
D. save our precious fuel
B. several hundred years
C. several billion years
D. several thousand years
B. Energy from natural gas would not pollute our living environment.
C. Energy from the sun would not pollute our living environment.
D. Energy from oil would not pollute our living environment.
B. so we will build more power plants
C. and the supply of electricity will be rationed throughout the country
D. so we don"t need it

dare to follow any further.
The men did not take any 9 . However, scientists are 10 by the discovery, because the engineers
were all very educated people and scientists feel they can 11 what they described.
After the discovery, scientists returned to the forest and 12 some hair and measured footprints. About
20 inches appears to be the animal"s foot! Chinese scientists have now set up a special group to exchange
information and make a 13 of the forest. But in the meantime, some people 14 to believe that this half-

| Before a new type of airplane goes into service, every part of it is tested again and again. But there are two tests that are more important than all the others. The first is called the "tank test". A modern airplane must fly very high in the sky. Air must be pumped into the plane so that the passengers can breathe. The metal structure (结构) of the plane has to be very strong for this reason. When the plane is filled with air, the air presses against the skin of the plane inside. The pressure (压力) on a small window is like a huge foot that is trying to get out. If a small part of the plane were to fail, the plane would explode in the sky. To test the structure of the plane, the plane is lowered into a huge tank or container of water. Then it is filled with air. The pressure inside the plane is greater than it ever will be when it is high up in the air. Finally, there is an explosion. This does not cause so much damage inside the water tank as it would anywhere else. Engineers can discover which part of the plane has broken. Then that part is made stronger. The most dangerous test happens when the new plane is going through test flights in the air. The test pilot must find out exactly what happens when the engines (发动机) are all shut off at once. The plane begins to fall like a stone. It is the pilot"s job to find out how he can get control of the plane again. These two tests are examples of how planes are made safe before they ever carry passengers. | |||

| [ ] | |||
| A. the power of the airplane engines B. the amount of air in the plane C. the strength of the plane structure D. the pressure inside and outside the plane | |||
| 2. What will happen to the plane under the "tank test"? | |||
| [ ] | |||
| A. It will be tested by pilots. B. It will be broken. C. It will be made stronger. D. It will be filled with water. | |||
| 3. According to the text, why are test flights most dangerous? | |||
| [ ] | |||
| A. Too much air may get into the plane. B. The plane may explode in the air. C. The pilot may lose control of the plane. D. The engines may be damaged. | |||
| 4. What might be the most suitable title for the text? | |||
| [ ] | |||
| A. How Airplanes Are Made and Tested B. Two Important Tests on Airplanes C. The Importance of Flying Safely D. The Danger of Testing Airplanes | |||

| Most people feel lonely sometimes, but it usually only lasts between a few minutes and a few hours. This kind of loneliness is not serious. In fact, it is quite normal. For some people, though, loneliness can last for years. Now researchers say there are three different types of loneliness. The first kind of loneliness is temporary (暂时的). This is the most common type. It usually disappears quickly and does not require any special attention. The second kind, situational loneliness, is a natural result of a particular situation-for example, a family problem, the death of a loved one, or moving to a new place. Although this kind of loneliness can cause physical problems, such as headaches and sleeplessness, it usually does not last for more than a year. The third kind of loneliness is the most severe. Unlike the second type, chronic (长期的) loneliness usually lasts more than two years and has no specific cause. People who experience habitual loneliness have problems socializing and becoming close to others. Unfortunately, many chronically lonely people think there is little or nothing they can do to improve their condition. Psychologists are trying to find ways to help habitually lonely people for two reasons: they are unhappy and unable to socialize and there is a connection between chronic loneliness and serious illness such as heart disease. While temporary and situational loneliness can be a normal, healthy part of life, chronic loneliness can be a very sad, and sometimes dangerous condition. | |||
| 1. How would you treat temporary loneliness according to the passage? | |||
| [ ] | |||
| A. Talk to friends. B. Just ignore it. C. Go to see a doctor. D. Ask your teachers for guidance. | |||
| 2. "It" in the last sentence of the second paragraph refers to _____. | |||
| [ ] | |||
| A. temporary loneliness B. situational loneliness C. a new place D. sleeplessness | |||
| 3. Why do psychologists want to help chronically lonely people? | |||
| [ ] | |||
| A. Chronic loneliness can cause family problems. B. Chronic loneliness can cause serious illness. C. Chronic loneliness can not be overcome. D. Such people are harmful to society. | |||
| 4. What is the best title for the passage? | |||
| [ ] | |||
| A. Three kinds of loneliness B. Loneliness and Diseases C. Loneliness and Social Contacts D. Chronic Loneliness | |||

| When we can see well, we do not think about our eyes often. It is only when we can not see perfectly that we come to see how important our eyes are. People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly. People who are farsighted face just the opposite problem. They can see things that are far away, but they have difficulty reading a book unless they hold it at arm"s length. If they want to do much reading, they must get glasses too. Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some people"s eyes become cloudy because of cataracts. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them. When night falls, colors become fainter to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they can not see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark. | |||
| 1. We don"t know that our eyes are of great importance until _____. | |||
| [ ] | |||
| A. we think about our eyes B. we cannot see clearly C. we wear glasses D. we have to do much reading | |||
| 2. According to the passage, a _____ is more likely to be nearsighted. | |||
| [ ] | |||
| A. student B. doctor C. guard D. painter | |||
| 3. People who are farsighted _____. | |||
| [ ] | |||
| A. can do a lot of close work without glasses B. can only see things that are very close to their eyes C. have difficulty reading a book if they hold it at arm"s length D. can correct their eyes by glasses | |||
| 4. To see a small thing at night, it is better to look _____. | |||
| [ ] | |||
| A. with wide open eyes B. with half shut or narrowed eyes C. straight at it D. in a slightly different direction | |||

| Laptop computers are popular all over the world. People use them on trains and airplanes, in airports and hotels. These laptops connect people to their workplace. In the United States today, laptops also connect students to their classrooms. Westlake College in Virginia will start a laptop computer program that allows students to do schoolwork anywhere they want. Within five years, each of the 1500 students at the college will receive a laptop. The laptops are part of a ＄10 million computer program at Westlake, a 110-year-old college. The students with laptops will also have access to the Internet. In addition, they will be able to use e-mail to "speak" with their teachers, their classmates, and their families. However, the most important part of the laptop program is that students will be able to use computers without going to computer labs. They can work with it at home, in a fast-food restaurant or under the trees-anywhere at all! Because of the many changes in computer technology, laptop use in higher education, such as colleges and universities, is workable. As laptops become more powerful, they become more similar to desktop computers. In addition, the portable computers can connect students to not only the Internet, but also libraries and other resources. State higher-education officials are studying how laptops can help students. State officials are also testing laptop programs at other universities, too. At Westlake College, more than 60 percent of the staff use computers. The laptops will allow all teachers to use computers in their lessons. As one Westlake teacher said, "Here we are in the middle of Virginia and we"re giving students a window on the world.They can see everything and do everything." | |||
| 1. The main purpose of the laptop program is to give each student a laptop to _____. | |||
| [ ] | |||
| A. use for their schoolwork B. access the Internet C. work at home D. connect them to libraries | |||
| 2. Why is the word "speak" in the second paragraph in quotation marks (引号)? | |||
| [ ] | |||
| A. They don"t really talk. B. They use the computer language. C. Laptops have speakers. D. None of the above reasons is correct. | |||
