There is no doubt that for a long time college education has been accepted. All high school graduates ought to go, says conventional wisdom and statistical evidence, because college will help them earn more money, become “better” people, and learn to be more responsible citizens than those who don’t go.

But college has never been able to work its magic for everyone. And now that close to half our high school graduates are attending, those who don’t fit the pattern are becoming more numerous, and more obvious. College graduates are selling shoes and driving taxis; college students interfere(妨碍；干扰) with each other’s experiments and write false letters of recommendation in the fierce competition so as to get admitted into graduate schools. Others find no stimulation (激励) in their studies, and consequently have to drop out, which is often encouraged by college administrators.

Some observers say the fault is with the young people themselves--they are spoiled and they are expecting too much. But that’s a condemnation(指责) of the students as a whole, and doesn’t explain all campus unhappiness. Others blame the state of the world, and they are partly right. We have been told that young people have to go to college because our economy can’t absorb an army of untrained eighteen-year-olds. But disappointed graduates are learning that it can no longer absorb an army of trained twenty-two-year-olds,either.

1.What’s the main idea of the first paragraph, ___________________.

A. people have great expectations for college education.

B. people still have a low opinion of college education.

C. the author thinks youngsters should all go to college.

D. people now no longer challenge college education.

2.The reason why more young people drop out of college is that _________.

A. they can start selling shoes and driving taxis.

B. they are no longer motivated in their studies.

C. they compete for admission to graduate schools.

D. college administrators force them to do so.

3.Who contributes to campus unhappiness?

A. young students who are all spoiled and expecting too much.

B. our society that can’t offer enough jobs to college graduates.

C. young people as well as our society are to blame for all this.

D. our society that has not enough jobs for high school graduates.

Every year there are changes in climate in different parts of the world.Some of these changes are due to natural causes.However,some climate changes are caused by air pollution and these changes may increase.

If the pollution affects the level of carbon dioxide in the atmosphere,the results are likely to be serious.There is only a small part of carbon dioxide in the atmosphere.But it has an important function in keeping the balance between radiation from the sun entering the atmosphere and radiation leaving the Earth.Some of the radiation is absorbed by the Earth and some is radiated back into the atmosphere.The carbon dioxide in the atmosphere prevents some of the radiation from leaving the atmosphere.Thus the heat remains in the atmosphere and carbon dioxide helps to prevent the temperature of the Earth from falling.

If the proportion(比例)of carbon dioxide in the atmosphere is increased as a result of air pollution,the temperature of the atmosphere may rise.This might cause the ice in the North and South to melt.If this happened,the sea level could rise and parts of the Earth would be flooded.This is not quite likely but the possibility exists.

There is also a fairly strong possibility that the dust level in the atmosphere will rise as a result of industrial pollution.This dust pollution will reflect sunlight back onto space.If this happens,less sunlight will reach the Earth and the temperature will fall.

Another danger comes from the destruction(破坏)of the Earth’s vegetation(植物)such as the forest of Brazil,which is being cleared away for farmland and cities.Trees use carbon dioxide and their destruction may upset the balance of carbon dioxide in the atmosphere.

1.The main purpose of the passage is to tell us that 　　 .

A.the climate of the earth is always changing

B.air pollution has greatly affected the climate of the world

C.carbon dioxide has something to do with climate changes

D.the climate of the world is subjected to(使受到)dangers from air pollution

2.From this passage we learn that carbon dioxide 　　 .

A.helps to prevent the temperature of the Earth from rising

B.keeps much of the sun’s radiation from entering the atmosphere

C.plays an important part in keeping the balance of the temperature of the Earth

D.is one of natural causes of climate changes

3.Judging from this passage,if the level of carbon dioxide in the atmosphere went down,the temperature of the Earth would 　　 .

A.become higher　　　　 B.either rise or fall

C.become lower　　　　　 D.neither rise nor fall

4.Which of the following is not the possible serious outcome if air pollution is related to climate changes?

A.Parts of the Earth would be flooded one day.

B.More sunlight would reach the Earth.

C.The temperature of the Earth might rise.

D.The Earth’s vegetation might be destroyed.

Climate change has had a number of effects on cities around the world, including rising see levels. And, this has become an especially big problem for coastal cities. City officials must now prepare for higher tides on their coasts. The American city of Miami is one example. Located in South Florida, Miami is home to nearly 3 million people and billions of dollars in land and buildings.

Miami is one of the cities in America most at risk for rising sea levels. The waterfront is central to Miami’s culture and economy. But as the seas rise with climate change .the water will not stay put. Large parts of South Florida are in danger of being under water in the coming years. Across Biscayne Bay, the City of Miami Beach is making improvements - raising streets, adding water pumps and more.

It is costing the city a lot of money. Local communities will spend 500 million dollars for the improvements. Thankfully, the residents, the folks that are paying the bill for this work, realize that the cost of doing nothing is much greater. A possibility officials are discussing with residents is for city to buy homes in some places where flooding has been a problem. The city would then turn that land into parks of grassland that could hold the water.

Over time, the city may need to take bigger risks. Miami’s future depends largely on how much, and how fast, the oceans rise.

Caroline Lewis leads the climate activism group, the CLEO Institute. She says cities cannot avoid the need to move inland. But, she says，a well-planned withdrawal (撤退) could include measures to keep people safely in place for as long as possible. And, she says, the world could learn from such a model. In these two Florida cities built on wetlands, there remains a lot of hopefulness.

1.What threat does the city of Miami face?

A. It needs people’s support to keep safe.

B. It will be flooded with rising sea water.

C. It doesn’t know how to get out of trouble.

D. It needs much money to slop rising water.

2.What does the underlined part “stay put” in Paragraph 2 mean?

A. Keep rising.　　 B. Make trouble.

C. Remain still.　　 D. Spread in one direction.

3.What do the people there agree to do with their problem?

A. Leave as it is.　　 B. Get ready to flee.

C. Donate money for it.　　 D. Take action against it.

4.Which of the following best matches Caroline Lewis’ opinion?

A. Making coastal cities exist as long as possible.

B. Warning the world of such a natural disaster.

C. Ensuring people to live there safely forever.

D. Moving coastal cities to safe places soon.
