They are not present in other 29 drinks. The scientists say their discovery 30 why many people in southern Europe can eat fatty foods and still have a low risk of heart disease. People in France, for example, have lower 31 of heart disease than Americans do. Yet the traditional French diet includes butter, cheese and other foods high in cholesterol. This led the British scientists to examine another important part of the French diet red wine. Several earlier studies have suggested that people who drink 32 amounts of alcohol may reduce their risk of heart disease. The British team experimented with cells from the blood 33 of cows. 34 . They found that polyphenols from all of the red wines stopped production of a protein called endothelin-1 (内皮缩血管肽-1). 35 , which is a cause of heart disease. 36 . : Section A 1、C [解析] M: So, have you finished reviewing all the material for our history exam?

One morning, waking up very early from cold and hunger, he decided to go shooting in a wood near his home. The wood belonged to a rich gentleman, and Ben had no right to go there. But, in the wood there were lots of rabbits and birds that were good to eat, and Ben determined to take the risk. Suddenly he saw the owner, with a group of friends, coming towards him in the wood. There was a look of anger on the rich man's face as he saw the gun in Ben's hands. Ben's heart sank with fear, but he saw there was no hope of escape, [27] so he walked boldly up to these people and said to the gentleman, "Good morning, sir, and what has brought you out so early this morning?" The rich man, rather surprised, said he and his friends were taking a little exercise to get an appetite for their breakfast. Then, looking at Ben with suspicion, he said, "But why are you so early in the morning?" "Well, sir," said Ben, [26] [28] "I just come out to see if I could get a breakfast for my appetite. " [28] The whole crowd burst into laughter at Ben's ready wit, and with a smile the rich man walked on, leaving Ben to try his luck with the rabbits.17、A 18、C 19、A [解析] 29-32 Single and looking for love? How about advertising yourself to millions of possible partners? [32] For about ,100 a week, you can have a 12-meter high photograph of your face in the center of your city. It's called "billboard dating" and it's the latest way to find your perfect partner. Billboard dating started in 2003 in the north England. Now billboard photos are appearing all over the UK. The idea came from John Craig, the manager of an online dating agency called findyourpartner, com. [29] John believes that people respond more to billboard pictures than online ads. Secretary Sally Noland, 24, advertised her face on the back of a bus. "I never used a dating agency before," she says. [30] "But after I split up with my boyfriend I wanted him to see my face everyday!" Businessman James Ryman, 42, paid findyourpartner, corn to put his face in a busy London train station. "People can see you before they meet you, and that makes everything much easier!" he says. Billboard dating is a big success for findyourpartner, com. The website address appears on all the billboards. [31] Anybody who wants to contact the people in the photos goes to the website to find more information. John Craig has also introduced the service in Spain, the USA and Australia.20、C 21、B 22、B 23、D [解析] 33-35 Today, [33] we are going to talk about a special way some plants respond to being invaded by pests. The plants react by emitting a chemical signal, which acts like a call for help. Let's take corn plants for example. [34] Sometimes, caterpillars (毛虫) chewing on the corn leaves. When the caterpillar saliva mixes with the leaf, the plant releases a chemical scream that attracts wasps (黄蜂). The wasps respond to the signal by flying to the chewed leave, and laying their eggs on the caterpillars. The caterpillars die in the next few days as the wasp offspring (后代) nourish themselves by feeding them. Thus the corn plant prevents all its leaves from being eaten by the caterpillars. [35] This chemical scream is specific. It's only released after the plant has detected the caterpillar saliva. A plant that is cut in the other means does not give off the same signal, nor does an undamaged plant. This also explains how a wasp can find a caterpillar in a huge field of corn. Soybean, cotton and probably many other plants use similar type of defense against pests. By enhancing this natural response in plants, researchers might reduce, some day even eliminate the need for chemical pesticide, which can cause ecological damage. For example, scientists might breed plants for this screaming trait, or they might transplant specific genes to increase the release of the chemical signals.24、A 25、B Section C 26、blocked [解析] 36-46 British scientists may have discovered the reason why red wine appears to protect the heart. They say natural chemicals found in red wine appear to protect against (36) blocked blood passages. The chemical (37) substances are called polyphenols. They come from the outer (38) covering of grapes. They are not present in other (39) alcoholic drinks. The scientists say their discovery (40) explains why many people in southern Europe can eat fatty foods and still have a low risk of heart disease. People in France, for example, have lower (41) rates of heart disease than Americans do. Yet the traditional French diet includes butter, cheese and other foods high in cholesterol. This led the British scientists to examine another important part of the French diet red wine. Several earlier studies have suggested that people who drink (42) moderate amounts of alcohol may reduce their risk of heart disease. The British team experimented with cells from the blood (43) vessels of cows. (44) The scientists studied the effects of twenty-three kinds of red wine on the cow blood cells. They found that polyphenols from all of the red wines stopped production of a protein called endothelin-1. (45) This protein causes blood vessels to become smaller and is linked to hardening of the blood vessels, which is a cause of heart disease. (46) The scientists say people who already drink wine might consider drinking red wine to increase their protection against heart disease.27、substances 28、covering 29、alcoholic 30、explains 31、rates 32、moderate 33、vessels 34、The scientists studied the effects of twenty-three kinds of red wine on the cow blood cells 35、This protein causes blood vessels to become smaller and is linked to hardening of the blood vessels 36、The scientists say people who already drink wine might consider drinking red wine to increase their protection against heart disease
