 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

(   ) 2. Which of the following statements reflects the in formation in the passage?

   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

   C. the educational system is sound,and students must follow every rule

   D. the educational system in this country would benefit from a thorough evaluation

[文章大意]本文是一篇調査報告。文章調查了學生作弊的情況并對作弊的原因進行了分析。

1. C根據文章第一段中的"Cheating appears to have gained ac?ceptance among good and poor students alike.”可以推知,句子中的good and poor students alike和題干中的"…students who cheat can be academically weak or strong."是同義句,即好學生和壞學生與專業水平強和專業水平弱的學生意思相同。故選C.

2. A根據文章第二段中的"The pressure is not only from par?ents and friends but from yourself. To achieve. To succeed. It's almost as though we have to surpass people to achieve our own goals."可知,學生作弊的一部分原因是他們面臨的壓力很大。故選A. B、C項中的Only和never說得太絕對,D選項的內容與文章內容相反。

3. A根據文章最后一段的"…there is something wrong with the individuals who're doing it…"可知,who后用are證明是復數,即前文提到的學生們。故選A.

4. D根據文章最后一段中的"…chairman of the English De?partment at Amarillo sees the matter differently,blaming the rise in cheating on the way students evaluated."可知,學生作弊的原因是學生評價體系的問題。這與D選項一致。故選D.

  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.

   B. The experiment will be successful.

   C. Scientists will carry out the experiment.

   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

   C. The Reason for Global Warming

   D. The Influence of Aerosols

  Any passenger on the subway who caught a glimpse of me may have already thought that I was strange. In particular this gentleman sitting opposite me was staring at me,at the cheese bun on the floor in front of me,and then back at me. “Next stop,St Patrick Station. ” My stop was quickly coming up. I had minutes to either take the cheese bun,which nobody else was claiming (as a passenger probably dropped it by mistake and got off at a previous stop) ,or leave it there and hope that it didn’t go to waste.

  In those few minutes I felt my pride getting in the way. “What would other people on this subway think of me if I took the cheese bun? Would they think that I was poor and hungry? Would they think that I’m stealing?”

  The ignorant thing to do was say “yes” to any of those self-imposed (自我強加的) questions,which would only justify my ego. But then I’d get off the subway,walk a block up the street to my office,get settled at my desk,and despite feeling comfortable,warm,and being well fed myself for the whole day,there would be a weight of guilt and regret weighing on my consciousness.

  My thoughts were pushing me towards pride and ignorance when the truth was evident:this missing cheese bun is a gift for a homeless person who is hungry and cold. For me it is a gift to overcome a little bit of ego and pass along so much kindness. It was clear that the homeless person who would receive this cheese bun needed it just as much as I did.

  Just as the doors opened at my stop,I grabbed the cheese bun and exited the subway. It felt awesome and I didn’t care if people were looking or what they thought. Instead of going directly to my office as usual,I walked a few more blocks up to Queen’s Park where I have seen a homeless man sitting outside many times on my walk from the gym to my office. I always wanted to give him something. There he was this morning,wrapped in a sleeping bag.

(   ) 1. As the author was getting off the subway,he    

   A. felt worried about where to go because he was a stranger in this city

   B. was suffering from hunger as he was hurrying to work without breakfast

   C. couldn’t decide whether to take the cheese bun on the floor in front of him or not

   D. took a glimpse of all the passengers,especially the gentleman sitting opposite him

(   ) 2. What is mainly discussed in the 2nd paragraph?

   A. The author’s concern about others.

   B. The inner struggle within the author.

   C. The author’s reaction to the problem.

   D. The author’s opinion towards the issue.

(   ) 3. The author grabbed the cheese bun the moment before he got off because    .

   A. he thought it a waste to leave the cheese bun there

   B. it reminded him of a homeless man he had met recently

   C. nobody was noticing him as they were getting ready to get off

   D. he valued kindness more than his own pride after a careful thought

(   ) 4. From the text we can know the author was    .

   A. caring   B. generous

   C. selfish   D. timid (膽小的)

  If you’ve ever seen the way dog people interacted with their pets,it comes as no surprise that there’s some germ-exchanging going on there. A new study indicates that dog ownership specifically may be one of the biggest single contributors to what kinds of microbes living on your skin.

A team of researchers led by Se Jin Song at the University of Colorado,Boulder,took swabs (化驗標本) of the tongues,palms,forehead and faeces (排泄物) of members of 60 family households. Some of the families had children or household pets and some did not;dogs were the only pets swabbed.

  Researchers then analyzed the DNA of the bacteria they found to determine how diverse the bacteria populations were. Not surprisingly,family members who lived together had more bacteria in common than members of separate households. Bacteria on the skin were especially similar within households,probably because we pass microbes through the air,through direct contact,and via the surfaces we touch.

  The most surprising finding,however,was the large bacteria contribution Fidonad made. The skin bacteria of dog owners from different households were almost as similar as if they’d cohabited without a dog. Put another way,you and a friend across town who both own dogs share a skin ecosystem as alike as a married couple does.

  The reason for this appears to be that dogs harbor some kinds of bacteria that are rare on human skin. One in particular,a family of bacteria called Methylophilaceae,was abundant in the mouths of dogs sampled as well as the skin of their owners—indicating “a common occurrence of oral-skin transfer between dogs and their owners”,according to the results published in the journal Life.

(   ) 5. From the study,we know that    .

   A. some kinds of bacteria live on our skin because of dog ownership

   B. nobody finds it surprising that there should be some germ-exchanging between dogs and their owners

   C. only dog ownership contributes to the sort of microbes that live on our skin

   D. there would most probably be no microbe on our skin if it were not for dogs

(   ) 6. The research took the following factors into consideration EXCEPT    .

   A. varieties of swabs from members of 60 family households

   B. families with children or household pets

   C. families without children or household pets

   D. dogs being the only pets in the households

(   ) 7. Why did researchers analyze the DNA of the bacte ria they found?

   A. To search for the way microbes pass from one member of a family to another.

   B. To find out the exact number of the bacteria living on human skin and dog skin.

   C. To decide whether the bacteria were of the same kind or not.

   D. To prove that family members who lived together had the same bacteria as the members of separate households.

(   ) 8. What does this passage mainly tell us?

   A. It is unsafe to keep dogs because of microbes.

   B. How many kinds of bacteria live on people’s skin because of dog ownership.

   C. Dog ownership affects the kinds of microbes living on people’s skin.

   D. What are the similarities between people who keep dogs and those who don’t.
