【填空题】AV Clip 19: Exercise and Brain AV 19 Exercise and Brain.avi Watch the video clip three times and complete the following passage by filling in each blank with the word from the video clip. Just six months a moderate exercise may be enough to rejuvenate（使恢复活力）an aging brain. Researchers from University of Pittsburg at Illinois examined more than 30 studies on exercise and the brain. They found that regular physical activity can reduce the risk for mental (1)_________ with age, and in some cases may even (2)_________ age-related brain changes. One study compared walking to stretching exercises, and found that the (3)_______ who walked regularly had improvements in their attention skills and decision making ability in just 6 months’ time. Other researches show that people who are physically (4)______ tend to have slightly larger brains, suggesting that exercise may protect against brain (5)_______ with age. Similarly, patients with (6)_________ disease who are physically fit tend to have more white matters in their brains, perhaps providing a large mental(7)________. As for the best type of physical activity to protect the brain, researchers say (8)________exercises such as walking, swimming and biking appear to have the most benefits.

rson were hurt, he would lose the power of doing certain things. And so people thought that each part of the brain does a different job. But modem research discovered that this is not so, for it is not easy to show exactly what each part of the brain does. In the past fifty years there has been a great increase in the amount of research done on the brain. Scientists have found out the way the brain works is not so simple as people in general may think. Chemists fell us that about 100 000 chemical changes take place in the brain every second. Some recent researches also suggest that we can remember everything that happens to us. We, may not be able to think of the things we have heard and seen, but it is kept there in the storehouse (宝库 ) of the human brain. Earlier scientists thought that is not true. As long as the brain is given plenty of exercise, it keeps its power. It has been proved that an old person who has always been active in the mind has a quicker mind than a young person who has only done physical work without using much of his brain.

C、in a very simple way

D、more complicated than we thought

4.Which of the following is NOT true according to the text？()

A、Scientists are working hard at the researches on the brain.

B、As many as six million chemical changes take place in the brain every minute.

C、A young man doing physical labor is sure to have a much slower min

5.The more work we give to our brains()

12, boys and girls cry equally often. From then until age 18, the level of the hormone prolactin(催乳激素) rises in young women, until their blood contains 60 per-cent more than men' s. And prolactin affects the production of tears.

On the sociological side, men in particular are conditioned out of crying. From the age of 12 or 13, boys are told that crying shows a loss of control, that it is a sign of weakness. If men step outside the norm and show their feelings in the workplace, they run the risk of getting labels attached that are not complimentary.

Researches on conversations show that women are more likely to talk about feelings, men about activities. This is a reflection of our socialization. Also, men are more likely to express their opinions. It gives rise to women feeling enormous frustration about getting their views across. When women are crying at work, it's often out of sheer frustration, about not being able to get their needs identified, known, put across, and getting a response to them…There is a sense of "I'm not being taken seriously." The trouble is, if a woman cries in this situation, men are likely to say, "She's far too emotional." There are, though, a couple of arenas(活动场所) in which it seems to be acceptable for men to be emotional: sports and especially more recently, politics. An essay in Times magazine once reported on timely tears from former Presidents George Bush and Richard Nixon. The Times essay says 1988 presidential candidate Patricia Schroeder' s tears led some to describe her as "just another weak woman, temperamentally unfitted for the presidency". It concludes: "Men may weep, but women must prove them- selves made of sterner stuff."

The cause for women crying more often is that______。

A．women are born to be weaker than men

B．women have more prolactin in their bodies

C．men are taught not to cry

D．both B and C
