Can eating a chocolate bar every day really prevent age-related memory loss？ People would

say "No". Can eating chocolate cake for breakfast, lunch and dinner be good for your heart？ Again, they would say "No" , because that would be too good to be true. But new research shows that large amounts of flavanols(黄烷醇), substances found in cocoa(可可), tea and some vegetables, may reverse age-related memory failure. Another study is looking to see if high levels of cocoa flavanols can help prevent heart attacks and strokes. Flavanols found in dark chocolate are known to increase blood flow in the part of the brain that controls memory. They also help prevent heart disease by lowering blood pressure and " bad" cholesterol (腱固醇). A new study published online found that cocoa flavanols reverse minor memory loss in older adults. Dr. Scott Small, a professor at Columbia University, is the lead writer of a research paper describing the effects of cocoa flavanols on brain activity. The study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavanol drink made from cocoa beans or a low-level flavanol drink. For a period of three months, some subjects got 900mg of flavanol a day while the others got 10mg. Brain imaging and memory tests were given to each subject before and after the study. Dr. Small says that the subjects who had the high-level flavanol drink showed much improvement on memory tests. The researchers warn that more work is needed because this study was performed on a small group. Researchers at Womens Hospital in Boston recently announced plans to do just that.

The first paragraph indicates that

A．eating chocolate is good for one"s heart

B．people doubt the good effect of eating chocolate

C．eating chocolate may prevent memory loss

D．people should not eat too much chocolate

第7题

In the year 2100, the world is going to have a population of about 8 billion. Most scienti

sts agree that the most severe problem is food supply. Who is going to feed all these people？ Where is the food going to come from？ Are we going to have enough food？ Are we going to produce more artificial foods？ One way of improving the situation is for people to eat less meat. Why？ Because it takes 4 kilos of grain protein(蛋白质)to produce half a kilo of meat protein. Clearly, there is not going to be sufficient meat protein for 8 billion people. Therefore, it will also be necessary to change eating habits because meat is the main part of many people s food today. A possible solution to this latter problem is the soybean(大豆). The soybean plant produces beans which have a very high fat and protein content. Scientists can now make these look and taste like real meat. They can also make many other artificial products such as soybean milk, for example, which has a taste of milk and can be used in cooking in very much the same ways as cow s milk. In fact, one woman in the United States fed her family only on soybeans for a year! She gave them soybean beef, soybean chicken, soybean milk, and sometimes just soybeans. Possibly, we are all going to eat soybeans in the future and finally give up meat completely from our tables.

What is the main subject of the passage？

A．A solution to man"s food problem.

B．A solution to the population problem.

C．Advantages of soybean.

D．How to develop good eating habits.

听力原文： All right! Enough cookies, cola, and chips! It seems that junk food is all that the children want to eat these days.Television controls their tastes. The kids see well-known personalities eating potato chips, candy, and other processed food, and they want to be like their heroes. How do they do it？ They eat the same food. I wish there were more characters like old Popeye the sailor, who ate spinach and not French fries.

Just because I like brown rice, beans, and fresh vegetables, I don't expect my children to cat this "health food." I'm glad to cook traditional meals of meat and potato for them. I really can't be too upset with the kids because most adults aren't careful about what they eat. The other night, my wife and I went to a party where there was plenty to drink but very little for us to eat. They served hot dogs and hamburgers. I can't eat hot dogs, with all those preservatives, and hamburgers are filled with chemicals so that they look good. Besides the meat, they had sugar filled cookies and cake, and, of course, chips. Terrible! I don't want the world to change because of me, but I think that people should realize that there are alternatives to eating meat. They always tell me that I probably don't get my essential proteins. But I feel better than ever and I'm sure that it's because I'm vegetarian. I would really like to see more television advertisements which show the benefits of good, healthy, natural food.

(26)

A．Beans.

B．Cookies.

C．French fries.

D．Potato chips.

The unhealthy ingredients and low nutrition content of the food can make you less active a

nd lazy, new research shows. No surprises there.【C1】______, what is more shocking is that the energy-weakening effects of a junk food diet can persist,【C2】______after you switch to a healthy【C3】______. Two groups of female rats were fed different diets by researchers for a six-month period. One group ate unprocessed foods such as corn and fish meal【C4】______the other ate a diet【C5】______to imitate junk food; high in sugar, and lower in【C6】______. While understandably the group eating the junk food diet gained more weight than the other, they also【C7】______from fatigue and became less active and less【C8】______—ie: lazier. In fact, those rats fed junk food took twice as many, and longer breaks during tasks than the rats eating a healthy diet, even tasks which【C9】______rewards. What is even more【C10】______is that switching these rats back onto a nutritious diet at the end of six months for nine days didnt seem to reverse their weight gain or their learnt laziness. This could suggest that while an【C11】______case of bad food—say on holiday, will not have too much of a【C12】______effect if you generally eat a good diet and lead a healthy lifestyle. But those who eat a poor diet【C13】______the long term may actually become lazy and fatigued, as well as gaining weight and suffering the health consequences【C14】______being overweight. The research shows that switching【C15】______a healthy diet in the short term is unlikely to be【C16】______to reverse any of the side effects of a diet high in junk food. "Overweight people are often regarded as lazy and lacking【C17】______," says Blaisdell, a professor of psychology at UCLA "We【C18】______our results as suggesting that the idea commonly【C19】______in the media that people become fat because they are lazy is wrong. Our data suggest that diet-induced obesity is a cause,【C20】______an effect, of laziness. Either the highly processed diet causes fatigue or the diet causes obesity, which causes fatigue."

【C1】

A．Meanwhile

B．Therefore

C．However

D．Moreover
