Nowadays,there is a heated debate on whether pollutants should be cleaned in the air. Cleaning up the air,while good for our lungs,could make global warming worse. And the pollutants still go up around the air,along with carbon dioxide.
These pollutants are called aerosols and they include soot as well as mixtures of nitrogen (氮) and sulfur (硫) and other stuff into the air. Natalie Mahowald,a climate researcher at Cornell University,says,so far,scientists have mostly tried to understand what those aerosols do while they’re actually in the air.
“There are so many different kinds of aerosols,” she says. “Some are warm and some are cool. But in fact,humans are giving out a lot of extra aerosols,and they tend to cool for the most part. ”
The aerosols reflect sunlight back into space,or keep us cool. But it turns out that’s not all they do. These aerosols also influence how much carbon dioxide gets drawn out of the air by plants on land and in the sea.
“They can add nutrients,for example,to the ocean or to the land ,” Mahowald says. “But also while they’re in the atmosphere they can change the climate,and thus that also can influence the amount of carbon,the land or the ocean can take up. So there are quite a few different ways that aerosols can act on each other. ”
Mahowald’s results suggest that reducing those pollutants could be an even bigger problem than realized,when you consider that aerosols help remove carbon dioxide from the air by encouraging plant growth. Hard numbers on this effect are highly uncertain at the moment,but this could turn out to be quite significant.
And studying it is not easy because the effects aren’t well understood. For example,nitrogen can be a fertilizer (肥料) , but it can stop plant growing when nitrogen comes out of the air in acid form.
Right now it seems like we’re much more likely to clean up aerosol pollution,while increasing the amount of carbon dioxide in the air. So scientists,unfortunately,may have a chance to see whether this experiment on our planet should continue or not.
( ) 5. From Paragraph 2,we know that .
A. scientists have been aware of how aerosols work
B. Natalie Mahowald is an expert in climate
C. cleaning up the air is so popular
D. pollutants are under control so far
( ) 6. What does the last sentence of the passage imply?
A. Scientists will be in a dilemma.

D. Scientists have difficulty in the experiment.
( ) 7. Which of the following can be the best title of this passage?
A. Pollutants in the Air
B. The Experiment on the Planet

D. The Influence of Aerosols
[文章大意]本文主要介紹懸浮微粒在空中所起的作用及研究者對其作用的一些看法。
5. B細節理解題。由第二段第二句Natalie Mahowald的同位語"a climate researcher at Cornell University"可知B正確。
6. A句意猜測題。第七段開頭一句和第八段最后一句中的"should continue or not"說明研究的難度。故A最合適。而D選項屬于事實題，不是暗示推理題。
7. D主旨大意題。全文以aerosols為中心，說明它的影響，故D正確。其他選項要么范圍太大，要么太小，不夠全面，

Cheating is nothing new. But today,the Administrative Department for Education finds that examples of academic dishonesty on the part of students have become more frequent—and are less likely to be punished--than in the past. Cheating appears to have gained acceptance among good and poor students alike.
Why is student cheating on the rise? No one really knows. Some blame the trend on a general loosening of moral values among today’s youth. Others have attributed (歸因于) increased cheating to the fact that today’s youth are far more practical than their idealistic ancestors. Whereas in the late sixties and early seventies,students were filled with visions about changing the world,today’s students feel great pressure to survive and succeed. In interviews with students at high schools and colleges around the country,both young men and women said that cheating had become easy. Some suggested they did it out of hate for teachers they didn’t respect. Others looked at it as a game. Only if they were caught,some said,would they feel guilty. “People are com-petitive ,” said a second-year college student named Anna,from Chicago. “There is a potential fear. If you don’t do well,your life is going to be ruined. The pressure is not only from parents and friends but from yourself. To achieve. To succeed. It’s almost as though we have to surpass people to achieve our own goals. ”
Edward Wynne,editor of a magazine blames the rise in academic dishonesty in the schools. He claims that administrators and teachers have been too hesitant to take action. Dwight Huber,chairman of the English Department at Amarillo sees the matter differently,blaming the rise in cheating on the way students evaluated. “I would cheat if I felt I was being cheated ,” Mr Huber said. He feels that as long as teachers give short-answer tests rather than essay questions and rate students by the number of facts they can memorize rather than by how well they can combine and process information,students will try to beat the system. “The concept of cheating is based on the false belief that the system is legal and there is something wrong with the individuals who’re doing it ,”he said, “that’s too easy an answer. We’ve got to start looking at the system. ”
( ) 1. Educators are finding that students who cheat
A. have poor academic records
B. use the information in late years
C. can be academically weak or strong
D. are more likely to be punished than before

A. The pressure students faced with is partly the reason causing the student cheating.
B. Only the educational system and administrators are to blame for the rise in the cheating.
C. The 1960s’ visions of changing the world helped students never make mistakes.
D. Punishment for cheaters has always been severe in this country.
( ) 3. The underlined words “the individuals”in the last paragraph refer to
A. students who practise cheating
B. parents who put pressure on their children
C. school administrators who approve of short-answer tests
D. teachers who are too hesitant to take action against cheating
( ) 4. The author probably would agree with the point of view that .
A. students who cheat should be driven out of school
B. parents alone must take responsibility for the rise in student cheating

Worry problems are everywhere in our daily life. How to solve them? The answer is that we must equip ourselves to deal with different kinds of worries by learning the three basic steps of problem analysis. The three steps are：
Get the facts.
Why is it so important to get the facts? Unless you have the facts,you can’t possibly attempt to solve your problem intelligently. Without the facts,all you can do is wondering around in confusion. It is not an easy job to get facts. When you are worried,your emotions are riding high.1.
When trying to get the facts,you can pretend that you are collecting this information not for yourself but for some other person.2. You can also pretend that you are a lawyer preparing to agree. Try to get all the facts both on your side and the other side of the case. You will generally find the truth lies somewhere in between.
3. Whenever you are worried,write down the questions that make you worry. And write out all the various steps you could take and then the probable consequences of each step. For example,what am I worrying about? What can I do about it? Here is what I’m going to do about it. After carefully weighing all the facts,you can calmly come to a decision.
Act on that decision.
4. How can you break the worry habit before it breaks you? Crowd worry out of your mind by keeping busy. Plenty of action is one of the best ways to cure worry.5. If you know a situation is beyond your power,
say to yourself： “It is so;it can’t be otherwise. ”Don’t permit little things to ruin your happiness. Try to cultivate a mental attitude that will bring you peace and happiness.
