Smoking, which may be a pleasure for some people, is a series of discomfort for their fellows. Medical scientists have expressed their concern about effect of smoking on the health not only of those who smoke but also those who do not smoke. In fact, non-smokers who take in the air polluted by tobacco smoke suffer more than the smokers themselves. A great number of students are trying to persuade the university to forbid smoking in classrooms. Believe they are completely right in their aim. However, I think it more important to achieve this by calling on the smokers to use good judgment and to show concern for others. Smoking is not allowed in theaters, cinemas and in other public places. Therefore, smoking must be forbidden in our classroom. Although many people have passed away for having smoked a lot and we call on people to give up smoking, yet many more that are following will turn down what we say every day, above all, the young people smoke a lot more.

47． In the writer’s opinion, smoking does good to ________.

OK, I admit it: emoticons (表情符号) are popular. Some people even think they are fun. Many seem unable to get through an e-mail or Instant Message chat sentence without using one. Some feel that they add feeling and character to otherwise cold digital communications.

Some, however, such as editor and Hollywood scriptwriter John Blumenthal, blast (抨击) the use of emoticons as “infantile (幼稚的) just like the people who use them”  He believes that words themselves should be enough. “If you’re being funny, happy or sad, that should be apparent (明显的) from the comment that goes before the emoticon,” he argues.

In the eyes of Blumenthal, the use of emoticons is a gender issue. “Men don’t use emoticons very much. Maybe not at all,” he said. “Teenage girls and women seem to use them a lot. Maybe there’ s an emoticon gene.”

It’s an interesting opinion, but it is not shared by all.

In an interview with The New York Times, Dacher Keltner, professor of psychology at the University of California, said that emoticons are popular because our brains are programmed “to seek out representations of humanity”. He believes that they appeal not because they are shortcuts for the lazy, but because they tap into (融入) something beyond language. They reach to our need to be with and communicate with people.

All of these arguments may be somehow valid (正确的). Each one of us will choose to communicate in our own way. I do not have much time for emoticons. I tried to use one once and felt like I was stealing into a primary school class that I had no place being in. I’d rather let my words do the talking.

Friends, however, send me messages and e-mails full of emoticons. I have no problem with this. I don’t regard any of my friends as lazy or immature (不成熟的). It’s just a question of individuality. :)

We might like to think we're not influenced by other people, but a new study into the group-buying mechanisms（机制） - like those used on coupon（优惠券） sites such as Groupon and LivingSocial - reveals that telling buyers who come later to the offer how many have already signed up increases the number of purchasers.

Researchers at the University of Toronto's Rotman School of Management wanted to understand why group buying sites that have entered the market recently have enjoyed greater success than those operating a decade ago, such as Mercata and MobShop.

Earlier attempts typically left potential buyers waiting for days before confirming whether or not they had got the offer they had signed up for.

“We think one of the reasons group-buying has been successful recently is because of the short time horizon,” says Rotman Professor Ming Hu, who co-wrote the study with Professor Mengze Shi and PhD student Jiahua Wu. “It allows for a herding effect.”

Another reason is the use of an information structure that discloses to later arrivals how many have already signed onto the deal.

Researchers looked at two ways of designing the purchasing mechanism for a group buy: a simultaneous mechanism, where no one knows how many buyers have come before them, and a sequential（连续的） mechanism, where a second group of buyers has the advantage of knowing the size of the first group.

The researchers' analytical（分析的） model shows the most successful mechanism is the sequential one because it eliminates uncertainty for those coming later to the deal, and improves the confidence of those who sign on early, as they're able to track the numbers of those who come after them.

“That boosts confidence,” says Professor Hu, who teaches operations management. Deals for "luxury" services, versus everyday items, work better in a group buy scenario（方案） because they offer consumers a greater benefit.

40．It can be learned from the text that ______.

A. the short time horizon is the reason why group-buying has been successful.

B. a simultaneous mechanism is where a group of buyers has the advantage of knowing how many people have signed up.

C. a sequential mechanism allows a herding effect which boosts the confidence of the buyers.

D. researchers at the University of Toronto's Rotman School of Management carried out an experiment about why group buying sites entered the market successfully, such as Mercata and MobShop.

42．What can be the best title for the passage?

B. Secret for group-buying mechanism—herding effect.

On your life road, you may be knocked down（击垮） or even broken into pieces by your determination or unfavorable situations.
