Handshaking, though a European practice, is often seen in big cities of China. Nobody knows exactly when the practice started in Europe. It is said that long long ago in Europe when people met, they showed their unarmed hands to each other as a sign of goodwill. As time went on and trade in cities grew rapidly, people in cities began to clap each other’s hands to make a deal or to reach an agreement, This practice was later changed into shaking hands among friends on meeting or leaving each other. “Let’s shake (hands) on it” sometimes means agreement reached.
Do the Europeans shake hands wherever they go and with whomever they meet? No. Sometimes the Chinese abroad reach out their hands too often to be polite. It is really very impolite to give your hand when the other party, especially when it is a woman, shows little interest in shaking hands with you and when the meeting does not mean anything to him or her. Even if, for politeness, he holds out his unwilling hand in answer to your uninvited hand, just touch it slightly. There is generally a misunderstanding among the Chinese that westerners are usually open and straightforward, while the Chinese are rather reserved (保守的) in manner. But in fact some people in western countries are more reserved than some Chinese today. So it is a good idea to shake hands with a westerner only when he shows interest in further relations with you.

“Pay has little to do with motivation in the workplace”．That’s the argument put forward by best-selling author Daniel Pink in his new book, Drive: The Surprising Truth About What Motivates Us．“Pay for performance is supposed to be a folk tale,” he says．
Daniel argues that, if employees receive a basic level of payment, three other factors matter more than money: a sense of independence, of mastery over one’s labor, and of serving a purpose larger than oneself．For example, in 2008 at the offices of Best Buy’s Richfield, salaried workers there were allowed to organize their own work day, putting in only as many hours as they felt necessary to get their jobs done．Productivity increased by 35% according to The Harvard Business Review．
But the managers at Goldman Sachs aren’t exactly making some efforts to adjust．Like others on Wall Street, the banking giant argues that fat bonuses （extra rewards） are essential to make its numbers．“That’s exactly the attitude that leads to the recent financial crisis in the United States,” responds Daniel, “as managers always focus on short-term rewards that encourage cheating, shortcuts, and dishonest behavior．”
Moreover, the 45-year-old author and former Al Gore speechwriter refers to social-science experiments and experiences at such workplaces as Google and 3M．In one 2005 experiment he describes, economists working for the Federal Reserve Bank of Boston tested the power of incentives （激励） by offering cash rewards to those who did well in games that included reciting a series of numbers and throwing tennis balls at a target．The researchers’ finding: Over and over, higher incentives led to worse performance --- and those given the highest incentives did the poorest job．
From this and other cases, Daniel draws a conclusion that monetary incentives remove the element of play and creativity, transforming “an interesting task into a dull one．” It’s even possible, he adds, for oversized rewards to have dangerous side effects, like those of a drug dependency in which an addicted requires ever larger amounts．He refers to scientific testing that shows the promise of cash rewards increase a chemical in the brain similar to that brought on by cocaine or nicotine．
Daniel, however, is also aware that his company examples --- no GE, no IBM, no Microsoft --- hardly represent the commanding heights of the economy．But he thinks his approach will catch on, even in the biggest companies．“Managers tend to be realistic, and in time they will respond,” he says．
53．In his book, Drive: The Surprising Truth About What Motivates Us, Daniel Pink is promoting the idea that _____．
A．it is a money-driven society    B．all workers are not driven by money
C．money plays a key role in management  D．pay has nothing to do with workplaces
54．In Daniel’s point of view, many Wall Street managers are _______．
A．dishonest      B．considerate   C．short-sighted       D．ridiculous
55．In paragraph 5, the example of drug-taking is given to show _______．
A．money is as addictive as cocaine or nicotine
B．big rewards bring about dangerous side effect
C．nicotine and money bring the same chemical
D．workers do not need the incentives of money at all
56．We can learn from the last paragraph that _______．
A．Daniel’s approach will be popular in a wider field
B．realistic managers will first consider Daniel’s approach
C．Daniel’s approach meets the demand of economic crisis
D．GE, IBM and Microsoft will join in Daniel’s approach next

When a rather dirty, poorly dressed person kneels at your feet and puts out his hands to beg for a few coins, do you hurry on, not knowing what to do, or do you feel sad and hurriedly hand over some money? What should our attitude to beggars be? There can be no question that the world is full of terribly sad stories. It must be terrible to have no idea where our next meal is going to come from. It seems cruel not to give some money to beggars.
Certainly, most of the world’s great religions (宗教) order us to be open-hearted and share what we have with those less fortunate than ourselves. But has the world changed? Maybe what was morally (道德方面) right in the old days, when one knew exactly who in the village had suffered misfortune and needed help, is no longer the best idea. Quite a few people will not give to beggars. Let us look at their arguments.
First, some believe that many city beggars dress up on purpose to look pitiable and actually make a good living from begging. Giving to beggars only encourages this sort of evil (恶行). Secondly, there is the worry that the money you give will be spent on beer, wine or drugs. Thirdly, there is the opinion that there is no real excuse for begging. One might be poor, but that is no reason for losing one’s sense of pride and self-dependence.
Related to this is the opinion that the problem should be dealt with by the government rather than ordinary people. Some people think beggars should go to the local government department and receive help.
It is hard to come to any final conclusion; there are various cases and we must deal with them differently. A few coins can save a life in some situations, and even if the money is wasted, that does not take away the moral goodness of the giver.
59. What is mainly discussed in the passage?
A. Moral deeds of people.         B. Religious activities of the church.
C. Moral goodness of the giver.     D. Arguments on giving to beggars.
60. What can we infer from the sentence “But has the world changed?” in the second paragraph?
A. People no longer know who suffers misfortune in the village.
B. Some people will not do what was morally right in the past .
C. We don’t meet with those who need help any more.
D. Now it is the government’s duty to help the beggars.
61. Which of the following is NOT mentioned in the passage?
A. Some people dress up to pretend to be beggars.
B. Some beggars want money to help their children go to school.
C. Some beggars use the money to buy drugs.
D. Some beggars have no excuse for begging.
62. In the last paragraph, the writer thinks that it is hard to come to any final conclusion, because______.
A. the cases can be so different
B. there are so many beggars
C. there is so much money wasted
D. there are so many different arguments

A breathtaking trick potentially left over from our ancestors might be found in us — the ability to sense oxygen through our skin.
Amphibians, animals such as frogs that can live both on land and in water, have long been known to be capable of breathing through their skin. In fact, the first known lungless frog that breathes only through its skin was discovered recently in the rivers of Borneo.
Now the same oxygen sensors found in frog skins and in the lungs of mammals (哺乳动物) have unexpectedly been discovered in the skin of mice.
“No one had ever looked,” explained Randall Johnson, a biologist researcher.
Mice and frogs are quite distant relatives, so the fact they have these molecules (分子) in common in their skin suggests they might well be found in the skin of other mammals, such as humans.
“We have no reason to think that they are not in the skin of people too,” Johnson said.
These molecules not only detect oxygen, but help increase levels of vital red blood cells, which carry oxygen around the body. Normal mice breathing in air that is 10 percent oxygen—a dangerously low level similar to conditions at the top of Mount Everest, and about half that of air at sea level. However, mice that had the oxygen sensor HIF-1a genetically removed from their skin failed to produce this hormone (荷尔蒙) even after hours of such low oxygen.
These findings, if they hold true in humans, suggest one could raise the level of oxygen circulating inside the body. This could help treat lung diseases and disorders such as anemia (贫血症) without injecting drugs, which make up a multibillion-dollar market, Johnson said.
Athletes also often try to get more oxygen delivered to their muscles in order to improve their performance. They often do this by training at high altitudes or in low-oxygen tents. The new study suggests they might want to expose their skin as well as breathing in low-oxygen air to improve their performance. “It’s hard to say what exactly might be done, however—there’s a lot we don’t know yet,” Johnson explained.
The scientists detailed their findings in the April 18 issue of the journal Cell.
