1、Light Night, Dark StarsThousands of people around the globe step outside to gaze at their night sky. On a clear night, with no clouds, moonlight, orartificial lights to block the view, people can see more than 14,000 stars in the sky, says Dennis Ward, an astronomer(天文學(xué)家) with the University Corporation forAtmospheric Research( UCAR) in Boulder, Colo. But when people are surrounded by city lights, he says, they\'re lucky to see 150 stars.If you\'ve ever driven toward a big city at night and seen its glow from a great distance, you\'ve witnessed light pollution. It occurs when light from streetlights, office buildings, signs, and other sources streams into space and illuminates (照亮) the night sky. This haze (朦朧) of light makes many stars invisible to people on Earth. Even at night, big cities like New York glow from light pollution, making stargazing difficult.Dust and particles of pollution factories and industries worsen the effects of light pollution. "If one city has a lot more light pollution than another," Ward says, "that city will suffer the effects of light pollution on a much greater scale."Hazy skies also make it far more difficult forastronomers to do their jobs.Cities are getting larger. Suburbs are growing in once dark, rural areas. Light from all this new development is increasingly obscuring (使變模糊) the faint (微弱的) light give off by distant stars. and if scientists can\'t locate these objects, they can\'t learn more about them.Light pollution doesn\'t only affect star visibility. It can harm wild life too. It\'s clear that artificial light can attract animals, making them go off course. There\'s increasing evidence, forexample, that migrating (遷徙) birds use sunsets and sunrises to help find their way, says Sydney Gauthreaux Jr. , a scientist at Clemson University in South Carolina, "When light occurs at night," he says, "it has a very disruptive (破壞性的) influence." Sometimes birds fly into lighted towers, high - rises, and cables from radio and television towers. Experts estimate that millions of birds die this way every year.How does light pollution affect wildlife? ______【單選題】
A.Animals may go off course.
B.It helps migrating birds find their homes.
C.Animals are afraid to go out after sunset.
D.It helps birds fall asleep.
正確答案:A

2、The orangutanAmong all the animals, the ape is most like human beings. Both people and apes have the similar brain structure, the similar nerve system, and the similar kind of blood. There are four kinds of apes: the chimpanzee (黑猩猩), the orangutan (猩猩), the gorilla (大猩猩), and the gibbon (長臂猿). They live in the deep forests and warm tropical regions of Africa and of Southeast Asia, including Indonesia. All apes are covered with brown, reddish-brown, orblack hair everywhere on their bodies except their faces, feet, and hands. Their hands each have four fingers and a thumb that helps them grip things the way our thumbs help us. But they also have a thumb on each foot instead of a big toe. Thus they can hold things with their feet also. Having short, weak legs, apes do not walk on the ground very much. However, their arms are very strong. This enables them to swing from branches and travel very quickly from tree to tree. These animals live in small family groups that move from place to place in search of vegetables and fruits. They also eat eggs, small animals, nuts, and insects. When they are tired, they build nests in the trees. But they rarely sleep there formore than a night ortwo. Then they move on to look formore food. There are some differences among the following three kids of apes. The gibbon is never more than three feet high and weight only about fourteen pounds. The gorilla grows to be six feet tall and weight up to 600 pounds. The orangutan is smaller than the gorilla. It stands three to five feet tall and weight up to 200 pounds. Chimpanzees are the smartest of all apes. They can be taught to sit at a table and eat, to dress themselves, and to do things that human children can do. What does the first paragraph tell us?【單選題】
A.The ape looks like human beings most.
B.People and the ape think alike.
C.People and the ape behave alike.
D.The ape is the most intellectual animal in the world.
正確答案:A
答案解析:由文章首句可知,在自然界中,猿與人最相似,故選A。
3、BudgetA budget is a spending plan. It can help you spend money wisely. It can do this by cutting out wasteful spending. Of course, preparing a budget takes planning, and following a budget takes will power. Your budget should meet your family\'s needs and income. The first step in creating a budget is to setyour goals. What does your family need and wants. You must know this to work out the details of the budget. Keep goals realistic, in terms of income available. Then decide which goals are the most important. The next step is estimating family income. Before you can plan wisely, you need to know how much money you have to spend! Write down all the money you expect to receive (wages, savings, interest, etc.) during the planned budget period. After you have calculated how much money will be available, it is time to estimate expenses. List all of your family expenses. If you are not satisfied with what you got foryour money, look carefully at your spending. Studying your records will show where overspending has occurred. It will also point out poorbuying habits. It is also a good idea to setaside a small amount of money foremergencies. Every family has small emergencies: a blown tire, a broken device, orthe need forminormedical care. According to the passage, what is the advantage of a budget?【單選題】
A.It can help you setyour goals clearly.
B.It can help you save a lot of money.
C.It can help you get rid of poorbuying habits.

答案解析:第1段第2句“It can help you spend money wisely”(預(yù)算幫助你聰明地花錢),也就是說理智地消費(fèi)( spend money in a reasonable way)。
4、Seeing Red Means Danger AheadThe colorred often means danger and by paying attention, accidents can be prevented. In the future, the colorred also may help _____ danger at construction sites. Thanks to new work by engineers, bridge supports orother kinds of materials, could one day contain a color- changing material. It will turn red before a structure collapses orfalls apart.The secret behind the color- changing material is a particular type of molecule (分子). A molecule is agroupof atoms (原子) held together by chemical bonds. Molecules come in all shapes and sizes and make up everything you can see, touch orfeel. How a molecule behaves depends on what kinds of atoms it contains and how they\'re held together.When a polymer (聚合物) containing a color- changing molecule called a mechanophore (機(jī)械響應(yīng)性聚合物) is about to break, it produces a color. When a polymer with mechanophore molecules becomes "injured" orweak, one of the mechanophore bonds breaks and the material turns red. "It\'s a really simple detection method," says Nancy Sottos, one of the scientists who worked on the project. Sottos and her team tested the color- changing polymers in their lab. The test results proved encouraging.There is a way to get rid of the red colorlight. When a bright light is shone on the mechanophore, the broken bond is fixed and the red colordisappears. Thus "self - healing" may be a problem forengineers. They need to use the color- changer in big construction projects that will be outside, under sunlight. and sunlight will make the mechanophore\'s warning system useless.Sottos and her fellow scientists still have a lot of work to do before the color- changing molecules can be used outside the lab.【單選題】
A.throw
B.prevent
C.create
D.keep
正確答案:B
答案解析:本題難度不大,考查的是動(dòng)詞的詞義辨析,干擾項(xiàng)干擾不大,此處是說,“在未來,紅色可以幫助建筑場所阻止危險(xiǎn)的發(fā)生”,答案是B。
5、The carCars are an important part of life in the United States. Without a car most people feel that they are poor. and even if a person is poorhe doesn\'t feel really poorwhen he has a car. Henry Ford was the man who first started making cars in large numbers. He probably didn\'t know how much the car was going to affect American culture. The car made the United Stated a nation on wheels. and it helped make the United States what it is today. There are three main reasons why the car becomes so popular in the United States. First of all, the country is a huge one and Americans like to move around in it. The car provides the most comfortable and cheapest form of transportation. With a car people can go anylace without spending a lot of money. The second reason cars are popular is the fact that the United States never really developed an efficient and inexpensive form of public transportation. Long-distance trains have never been as common in the country as they are in other parts of the world. Nowadays there is a good system of air-service provided by planes. But it is too expensive to be used frequently. The third reason is the most important one, though. The American spirit of independence is what really made cars popular. Americans don\'t like to wait fora bus, ora train oreven a plane. They don\'t like to have to follow an exact schedule. A car gives them the freedom to schedule their own time. and this is the freedom that Americans want most to have. The gas shortage has caused a big problem forAmericans. But the answer will not be a bigger system of public transportation. The real solution will have to be a new kind of car, one that does not use so much gas. The real solution to the gas shortage problem is【單選題】
A.to make less cars
B.to develop a public transportation system
C.to make gas-saving cars
D.to develop train service
正確答案:C
答案解析:文章最后一句“The real solution will have to be a new kind ofcar, one that does not use so much gas”,不使用很多汽油的車,當(dāng)然就是gas-saving cars(節(jié)能汽車)了。
