The process of curing a disease is like a war different soldiers fight against an enemy．A.whenB.whereC.whatD.that 题目和参考答案——青夏教育精英家教网—

Online shoppers would rather receive an offer for a product or service than make their own offer ₃ according to a study led by a Michigan State University scholar that has implications for the fast-growing e-commerce industry. The findings may come as a surprise given that shopping online is an anonymous(匿名的）process that seemingly can give consumers more confidence to drive a hard bargain_,said Don Conlon ，Professor of Management in MSU’s Broad College of Business.

But the study found that participants who made their own offers were less successful in sealing the deal and ，when they were successful_? worried they overpaid Many shoppers found the process of researching an offer to be a hassle. “ Americans are very busy，and it’s less time-consuming to be the one receiving the offer rather than the one proposing the offer ” Conlon said. ^u People tend to be happier when they’re in the receiver role. ”

Online spending in the United States is expected to jump 45 percent in the next four years， from $ 226 billion this year to $ 327 billion in 2017，according to Forrester Research Inc. Nevertheless, researches into this prosperous market remain largely focused on the strategies of companies, rather than those o£ shoppers. Conlon^’s study is ，obviously, a rare exception.

Conlon got the idea for the study after considering the difference between two popular sites for hotels and airline flights, priceline.com, which takes bids, and hotwire.com ，which provides offers. Using these two models ，Conlon and his fellow researchers conducted a series of experiments with more than 850 people who were charged with booking a fictional hotel room and acquiring a fictional antique car. Not only did participants prefer to receive bids, Conlon said ，but they also secured more deals in that receiver role. Further ，when they had to make the bids ，they were left more mentally taxed and regretful.

From an industry perspective，putting customers in the receiver role may help fill more hotel rooms and airplane seats. “If you’re a business with a lot of products₃ ” Conlon said，“you may want to be the one making the offers. ” However, when selling single items, such as an antique car， accepting bids may be a better option since that typically drives up the price, he said.

We produce 500 billion of plastic bags in a year worldwide and they are thrown away polluting oceans, killing wildlife and getting dumped in landfills where they take up to 1,000 years to decompose. Researchers have been unsuccessfully looking for a solution.

The 16-year-old Canadian high school student, Daniel Burd, from Waterloo Collegiate Institute, has-discovered a way to make plastic bags degrade(降解) in as few as 3 months, a finding that won him first prize at the Canada Wide Science Fair, a ＄10,000 prize, a ＄20,000 scholarship, and a chance to revolutionize a major environmental issue.

Burd’s strategy was simple: Since plastic does eventually degrade, it must be eaten by microorganisms (微生物). If those microorganisms could be identified, we could put them to work eating the plastic much faster than under normal conditions.

With this goal in mind, he grounded plastic bags into a powder and concocted(调制) a solution of household chemicals, yeast(酵母) and tap water to encourage microbes growth. Then he added the plastic powder and let the microbes work their magic for 3 months. Finally, he tested the resulting bacterial culture on plastic bags, exposing one plastic sample to dead bacteria as a control. Sure enough, the plastic exposed to the live bacteria was 17% lighter than the control after six weeks.

The inputs are cheap, maintaining the required temperature takes little energy because microbes produce heat as they work, and the only outputs are water and tiny levels of carbon dioxide.

“Almost every week I have to do chores and when I open the closet door, I have piles of plastic bags falling on top of me. One day, I got tired of it and I wanted to know what other people are doing with these plastic bags. The answer: not much. So I decided to do something myself.” Said Daniel Burd.

Who's in control of your life? Who's pulling your strings? For the majority of us, it's other people-society, colleagues, friends, family or our religious community. We learned this way of operating when we were very young, of course. We were brainwashed. We discovered that feeling important and feeling accepted was a nice experience and so we learned to do everything we could to make other people like us. As Oscar Wilde puts it, "Most people are other people. Their thoughts are someone else's opinions, their lives a mimicry, their passions a quotation."

So when people tell us how wonderful we are, it makes us feel good. We long for this, good feeling like a drug—we are addicted to it and seek it out wherever we can. Therefore, we are so eager for the approval (赞同) of others that we live unhappy and limited lives, failing to do the things we really want to. Just as drug addicts and alcoholics live worsened lives to keep getting their fix（一剂毒品）, we worsen our own existence to get our own constant fix of approval.

But, just as with any drug, there is a price to pay. The price of the approval drug is freedom—the freedom to be ourselves. The truth is that we cannot control what other people think. People have their own agenda, and they come with their own baggage and, in the end, they're more interested in themselves than in you. Furthermore, if we try to live by the opinions of others, we will build our life on sinking sand. Everyone has a different way of thinking, and people change their opinions all the time. The person who tries to please everyone will only end up getting exhausted (tired) and probably pleasing no one in the process.

So how can we take back control? I think there’s only one way make a conscious decision to stop caring what other people think. We should guide ourselves by means of a set of values—not values imposed from the outside by others, but innate values which come from within. If we are driven by these values and not by the changing opinions and value systems of others; we will live a more authentic, effective, purposeful and happy life.

1.What Oscar Wilde says implies that________.

A. most people have a variety of thoughts

B. we have thoughts similar to those of others

C. other people's thoughts are more important

D. most people's thoughts are controlled by others

2.What does the author try to argue in the third paragraph?

A. Changing opinions may cost us our freedom.

B. We may lose ourselves to please others.

C. We need to pay for what we want to get.

D. The price of taking the drug is freedom.

3. It can be concluded from the passage that_______.

A. it's better to do what we like

B. we shouldn't care what others think

C. we shouldn't change our own opinions

D. it's important to accept others' opinions

4.The author tries to persuade the readers to accept his arguments mainly by________.

A. analyzing causes and effects B. providing examples and facts

C. discussing questions D. making suggestions

第一节（共15小题；每小题2分，满分30分）

　　阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

A

　　Soon it may be harder to stop and smell the roses.

　　Growing levels of air pollution from power plants and automobiles have reduced flower fragrances (芬芳) by up to 90 percent in the US.That is compared with pre-industrial levels,a new study has found.

　　The trend is unpleasant for human noses,but may be life - threatening for bees and butterflies.

　　"Many insects find flowers by folowing the scent(香味) produced by those flowers," said the studies lead author Jose D.Fuentes,an environmental scientist at the University of Virginia.

　　"The increasing pollution makes it difficult for them to locate the flowers and feed on their nectar(花蜜)."

　　Scientists have alrady known that flowers produce scent molecules(分子) that bond with pollutants.The process breaks down the plants' sweet smell.

　　With more pollution in the air,the scent molecules don't remain effective as long and travel shorter distances on the wind.

　　The new study suggests that in the mid - 19th century,when pollution levels were first recorded,scent molecules would have been able to travel some 1,000 to 1,200 meters.

　　Today,in the polluted air found downwind of large cities,scentst may only make it some 200 to 300 meters.

　　The report was recently published in the journal,Atmospheric Environment.

　　Bee farmers have reported that bee populations are dropping dramatically in many parts of the world in recent years. Could these missing scents be a factor?

　　Scientists trying to hind the cause of bee population declines have blamed bacteria,pesticides,and even cellphone radiation.

　　Jay Evans,an entomologist(昆虫学者) at the US Department of Agriculture's bee research laboratory,was interested in the new study.But he says he hasn't seen bee behavior that suggests trouble with scents.

　　"Over the last couple of summers I don't think the bees in this area were bringing in much less food,"he said.

　　"It might be that they had to work harder,but it seems like as long as there were bees to collect food they were finding flowers somewhere."

　　But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats.

　　"The effects shown in these studies will simply exacerbate whatever the bees are going through right now,"he said.

　　"It's something that is really worthwhile paying attention to."

　　56.What's the passage mainly about?

　　　A.How greatly air plooution affects our lives.

　　　B.Effects of air pollution on bee populations.

　　　C.Measures to fight air pollution.

　　　D.The rapid decline of bee populations in the world.

　　57.According to the passage,Jay Evans probably agrees that ______ .

　　　A.bees are the insect that suffers most from air pollution

　　　B.bees are at risk of dying out owing to air pollution

　　　C.the fading smell of flowers doesn't affect bees so greatly as was thought

　　　D.as is often the case,bees fail to locate the flowers because of the missing scents

　　58.The word"exacerbate" in the last paragraph but one probably means ______.

　　　A.worsen B.improve C.get rid of D.decrease

　　59.Which of the following is NOT true according to the passage?

　　　A.The more air pollution there is in a region,the greater the destruction of the flower scents.

　　　B.Bacteria,pesticides,and cellphone radiation are blamed for causing the decline of bees.

　　　C.The scent molecules produced by flowers in a less polluted environment oculd travel longer and farther.

　　　D.Air pollution does more harm to insects such as bees and butterflies than human beings.

The process of curing a disease is like a war ________ different soldiers fight against an enemy．
