Professor Taiju Matsuzawa wanted to find out why otherwise healthy farmers in northern Japan appeared to be losing their ability to think and reason at a relatively early age, and how the
process of aging could be slowed down.With a team of colleagues at Tokyo National University,
he set about measuring brain volumes of a thousand people of different ages and jobs.
Computer technology enabled the researchers to get right measurements of the volume of the front and side sections of the brain, which relate to intellect and emotion, and determine the human character. Contraction (收缩) of the front and side parts as cells died was observed in some subjects in their thirties, but it was still not clear in some sixty and seventy-year-olds.Matsuzawa concluded from his tests that there is a simple remedy (补救) to the contraction normally associated with age using the head.
The findings show in general terms that contraction of the brain begins sooner in people in the country than in towns. Those least at risk, says Matsuzawa, are lawyers, followed by university professors and doctors. White collar workers doing routine work in government offices are, however, as likely to have shrinking (萎缩) brains as farm workers, bus drivers and shop assistants.
Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must circulate properly in the head to supply the fresh oxygen the brain cells need. "The best way to keep good blood circulation is through using the brain," he says, "Think hard and engage in conversation. Don't rely on pocket calculators."wThe team of doctors wanted to find out ______.
| A．why certain people age sooner than others | B．how to make people live much longer |
| C．the size of certain people's brains | D．the people with more intelligence |
On what are their research findings based?
| A．A survey of farmers in northern Japan. |
| B．Tests performed on a thousand old people. |
| C．The study of brain volumes of different people. |
| D．The latest development of computer technology. |
Matsuzawa thinks that _______.
| A．our brains grow as we grow older |
| B．the front section of the brain does not shrink |
| C．sixty-year-old people have better brains than thirty-year-olds |
| D．the contraction of brains is connected with brain exercise |
According to the passage, which people seem to age slower than others?
| A．Farmers. | B．Lawyers. | C．Government workers. | D．Shop assistants.w |
I don't ever want to talk about being a woman scientist again. There was a ti
me in my life when people asked constantly for stories about what
it's like to work in a field dominated by men. I was never very good at telling those stories because truthfully I never found them interesting. What I do find interesting is the origin of the universe, the shape of space-time and the nature of black holes.
At 19, when I began studyi
ng astrophysics(天体物理学), it did not bother me in the least to be the only woman in the classroom. But while earning my Ph.D. at MIT and then as 3 post-doctor doing space research, the issue started to bother me. My every achievement—jobs, research papers, awards— was viewed through the lens of gender (性别) politics. So were my failures. Sometimes, when I was pushed into an argument on left brain versus (相对于) right brain, or nature versus nurture (培育), I would instantly fight fiercely on my behalf and all womankind.
Then one day a few years ag
o, out of my mouth came a sentence that would eventually become my reply to any and all provocations: I don't talk about that anymore. It took me 10 years to get back the confidence I had at 19 and to realize that I didn't want to deal with gender issues. Why should curing sexism be yet another terrible burden on every female scientist? After all, I don't study sociology or political theory.
Today I research and teach at Barnard, a women's college in New York City. Recently, someone asked me how many of the 45 students in my class were women. You cannot imagine my satisfaction at being able to answer: 45. I know some of my students worry how they will manage their scientific research and a desire for children. And I don't dismiss those concerns. Still, I don't tell them "war" stories. Instead, I have given them this: the visual of their physics professor heavily pregnant doing physics experiments. And in turn they have given me the image of 45 women driven by a love of science. And that's a sight worth talking about..
From Paragraph 2, we can infer that people would attribute(归因于) the author's failures to_____.
| A．the very fact that she is a woman |
| B．her involvement in gender politics |
| C．her over-confidence as a female astrophysicist |
| D．the burden she bears in a male-dominated society |
.
What did the author constantly fight against while doing her Ph.D. and post-doctoral research?
A. Lack of confidence in succeeding in space science.
B. Unfair accusations from both inside and outside her circle.
C. People's stereotyped attitude towards female scientists.
D. Widespread misconceptions about nature and nurture.
Why does the author feel great satisfaction when talking about her class?
| A．Female students no longer have to worry about gender issues. |
| B．Her students' performance has brought back her confidence. |
| C．Her female students can do just as well as male students. |
| D．More female students are pursuing science than before. |
.
What does the image the author presents to her students suggest?
| A．Women students needn't have the concerns of her generation. |
B． Women have more barriers on their way to academic success. |
| C．Women can balance a career in science and having a family. |
| D．Women now have fewer discrimination problems about science career. |
Job sharing refers to the situation in which two people divide the responsibility of one full-time job．The two people will
ingly act as part-time workers, enough hours between them to fulfill the duties of a full-time worker．If they each work half the job, for example, they each receive 50 per c
ent of the job's wages, its holidays and its other benefits．
Job sharing differs from conventional （常规的） part-time work in that it occurs mainly in the more highly skilled and professional areas, which require higher levels of responsibility and employee commitment． Job sharing should not be confused with the term work sharing, which refers to increasing the number of jobs by reducing the number of hours of each existing job, thus offering more positions to the growing number of unemployed people．Job sharing, by contrast, is not designed to address unemployment problems; its focus, rather, is to provide well-paid work for skilled workers and professionals who want more free time for other activities．
As would be expected, most job sharers are women．A survey carried out in 1988 by Britain's Equal Opportunities Commission showed that 78 per cent of sharers were female, the majority of whom were between 20 and 40 years of age．Subsequent studies have come up with similar results．Many of these women were re-entering the job market after having had children, but they chose not to seek part-time work because it would have meant lower status．Job sharing also offered an acceptable shift back into full-time work after a long absence．
The necessity of close cooperation when sharing a job with another person makes the actual work quite different from conventional one-position jobs．However, to ensure a greater chance that the partnership will succeed, each person needs to know the strengths, weaknesses and preferences of his or her partner before applying for a position．Moreover, there must be a fair division of both routine tasks and interesting ones．In sum, for a position to be job-shared well, the two individuals must be well matched and must treat each other as equals．.
In what way is work sharing different from job sharing?
| A．Work sharing requires more working hours． |
| B．Work sharing is aimed at creating more jobs． |
| C．Work sharing provides a more satisfactory salary． |
| D．Work sharing depends on the employer's decision． |
.
According to Paragraph 4, young mothers preferred job sharing to conventional part-time work mainly because _____．
| A．they sought higher social status |
| B．they were over ideal working ages |
| C．they had difficulty finding full-time jobs |
D．they had to take care of both work and family |
.
In jo
b sharing the partners should _____．
| A．enjoy equal social status |
| B．have similar work experience |
| C．keep in touch with each other |
| D．know each other very well |
.
The main purpose of the passage is to ______．
| A．describe job sharing in general |
| B．discuss how to provide more jobs |
| C．recommend job sharing to women |
| D．compare job sharing with work sharing |

A few days ago my wife sent me out to buy something. When I came home, I handed(交给) her a paper bag and said, “Here are the apples you wanted.” She looked in the bag, and then she looked at me. “I told you,” she said slowly, “to buy some eggs.”
I felt worried about my absent-mindedness, so I went to see a doctor. He was a very kind man. “I have seen many people like you. It’s nothing to worry about,” he said. “If you know you are absent-minded, you are all right. But if you do not know you’re absent-minded, you may be really in trouble.”
“Many famous people were absent-minded,” the doctor told me. “Thomas Edison(爱迪生)was standing in line(排队) one day to pay his taxes(税). When he arrived at the window, he found that he had forgotten his own name. He had to ask the man who was behind him to tell him who he was.”
I felt much better and got up to leave. “Thank you, doctor,” I said. “How much do I have to pay you?”
“Ten dollars for the check-up(检查),” the doctor said.
“But doctor, I did not have a check-up!”
For a moment the doctor looked puzzled. Then he said, “Oh, yes, it was the patient before you who had a check-up. How absent-minded I am!”It can be inferred from Paragraph 1 that when the author’s wife heard what her husband told her, she was ______.

The world is filled with many interesting sounds. Some are very pleasant to hear; others are unpleasant to our ears. In a day, you probably hear hundre
ds of different sounds.
All sounds are different. Some may be soft; others may be loud. Some sounds are high; others are low.
Some sounds are useful. Without sound we c
annot talk or listen to one another. The ringing alarm clock (闹钟)makes people wake up. The hooting of a horn (喇叭声) on the road warns careless people of danger.
We make sounds by making things move to and fro(来回地). This to-and-fro movement is called vibration (振动). It means moving up and down or forwards(向前地) and backwards(向后的) very fast. This makes sound waves(波).
We can make sounds in many ways, for example, by shouting, clapping our hands and striking the table. We can make sounds only by making things vibrate. We can talk because we can make our vocal cords (声带) vibrate. Our vocal cords are in a sound box or voice box. Two vocal cords vibrate when our lungs(肺) force the air through them. We can make sounds ______.
| A．by making things still |
| B．by making things vibrate |
| C．by making things jump up and down |
| D．by changing the positions of things |
Some sounds are useful because ______.
| A．they can wake people up |
| B．they can warn people to be careful when they are crossing the road |
| C．they make it possible for people to talk or listen to each other |
| D．all of the above |
When the air is through our vocal cords, it can make them ______.
| A．vibrate | B．breathe the air |
| C．talk to each other | D．move forward and backward |
Sounds are different because ______.
| A．different sounds have different vibrations |
| B．different sounds have different sound waves |
