名牌中学课时作业系列答案The possibility that pleasant smells might reduce pain has recently been suggested by new research. In a scientific study, doctors asked 20 men and 20 women to keep their hands in very hot water for as long as possible while breathing in different smells.
As people believe that strong smells can affect the senses, volunteers were asked not to eat or drink for eight hours before the experiment began. During the experiment, volunteers were asked to take in pleasant smells such as vanilla (香草), and unpleasant smells such as durians (榴莲). The volunteers kept their hands in the water until it became too hot for them. When they could not bear the pain any more, they took their hands out of the water.
Scientists are interested in whether the senses or smell is related to pain and whether men and women have the same senses. Now, the study has proved that for women, pleasant smells reduce pain. For men, there is no change.
Dr Finkelstein has been studying smells since 1999. He says that scientists already have data from 40 volunteers. He adds that this year, scientists will test another 60 volunteers and will be in a better position to explain the results.
One explanation is that women’s sense of smell developed long ago, and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognized their children by sight only. Now, they have started to believe that the sense of smell also helps, but why pleasant smells do not reduce pain in men is a question still to be answered by scientists.

Who cares if money can’t buy you love? But it can still be your best friend forever．That’s one of the surprising findings in a new research paper, “The Power of Money”，published in me journal Psychological Science．
Like any best friend forever，money demonstrated to researchers its ability to soothe us，reduce our sense of social exclusion and even reduce life’s painful moments．
“I was surprised” says Katherine Vohs，one of the researchers and professor at the University of Minnesota’s Carlson School of Management．“The findings were surprising because no one had connected the meaning of money to pain．The money wasn’t buying the subjects more friends；it was only psychologically helpful.”
In the research ,students were told they would be participating in a test of finger dexterity(敏捷度)．One group was given some paper money to count，while the other group was given blank pieces of paper．Once the counting was complete, all the test subjects were asked to dip their fingers into bowls of water heated to 122 degrees—roughly the temperature of a very hot bath．
Result? Those who had been counting money reported less pain than those who had not．Subjects also were asked about their feelings．Those who handled actual money reported feeling stronger even 10 minutes after they put down the cash．
Combined with previous experiments，the findings confirmed what researchers have long doubted，that money acts as a general panacea(万能药)in the brain，giving us social self-confidence and reducing physical pain without having to spend a dime on aspirin．
But can we get the same effect by using credit cards? “No，credit cards do not have the same effect，” Vohs says．“They are scary for most people，and they in fact represent debt m many ways．”The findings could have an interesting effect in the business world, where recent trends have been to issue non-monetary rewards and bonuses instead of what was thought of as “cold, hard cash”．
【小题1】The underlined word “soothe” in Paragraph 2 is the closest in meaning to“____________” .
| A．encourage | B．remind | C．calm | D．trust |
| A．He found it totally unexpected． |
| B．He had no doubt about it． |
| C．He thought it needed further experiments． |
| D．He thought it was not convincing． |
| A．They were divided into two groups according to their ages． |
| B．One group was given paper money while the other was given coins． |
C．They were holding the money while dipping fingers into hot wat er． |
| D．Both groups were asked to dip fingers into hot water． |
| A．the effect of money can only last until we put it down |
| B．money is both psychologically and socially helpful to us |
| C．the result of the research hasn’t been confirmed（证实） by experts |
| D．credit cards have the same effect on us as money |
| A．the recent trend in the business world is to give cash as rewards |
| B．employers should give non-monetary rewards to employees |
| C．cash is a better way to reward employees than credit cards |
