7、总题数:1,分数:7.00)Using HIV Virus to Cure Cancer Scientists are planning to use human immunodeficiency(免疫缺陷)virus(HIV), one of mankinds most feared viruses, as a carrier of genes which can fight cancer and a range of diseases that cannot be cured. The experts say HIV has an almost perfect ability to avo
8、id the bodys immune(免疫的)defenses, making it ideal for carrying replacement genes into patients bodies, according to the Observer. A team at the California-based Salk Institute, one of the worlds leading research centers on biological sciences, has created a special new breed of HIV and has started n
9、egotiations with the US Food and Drug Administration(FDA)to begin clinical gene therapy(治疗) trials this year. The first trials are expected to involve patients suffering from cancers that cannot be cured by surgery although project leader Professor Inder Verma said the HIV technique would have” far
10、wider applications”. The plan remains very likely to cause controversy since it involves making use of a virus which has caused more than 22 million deaths around the world in the past two decades. Verma said that the idea of using HIV for a beneficial purpose was “shocking” but the fierce nature of
11、 HIV had disappeared by having all six of the potentially deadly genes removed. Illnesses such as various cancers are caused when a gene in a patients body fails to work properly. In the past two years, breakthroughs in genetics(遗传学)have led gene therapy scientists to try and replace the genes that
12、do not function normally. Unfortunately, the bodys immune defenses have been known to attack the modified genes and make them lose their effects before they can start their task and progress in the field has been held up by the lack of a suitable carrier. The HIV virus has the ability to escape from
13、, and then destroy, the immune defense cells designed to protect our bodies and this makes it attractive to scientists as a way of secretly conveying replacement genes into patients bodies. (分数:7.00)(1).FDA has approved the plan of using HIV to cure cancer in humans. (分数:1.00)A.RightB.WrongC.Not men
14、tioned(2).The idea of using HIV for a beneficial purpose has been widely accepted. (分数:1.00)A.RightB.WrongC.Not mentioned(3).HIV can be safely used to cure cancer only if the deadly genes have been removed. (分数:1.00)A.RightB.WrongC.Not mentioned(4).The HIV virus is an excellent warrior to fight the
15、bodys immune cells. (分数:1.00)A.RightB.WrongC.Not mentioned(5). Other countries are also expected to begin clinical gene therapy trials soon. (分数:1.00)A.RightB.WrongC.Not mentioned(6). It is the lack of money that has held up the progress in using replacement genes to cure cancer. (分数:1.00)A.RightB.W
16、rongC.Not mentioned(7).The HIV virus has caused more deaths in developed countries. (分数:1.00)A.RightB.WrongC.Not mentioned三、第 3 部分:概括大意与完成句子(总题数:1,分数:8.00)Exercising Your Memory 1 Aging does not mean a dramatic decline in memory power, unless you help it help by letting your mind go. 2 Thats not to
17、say that memory doesnt change throughout life. Researchers divide memory into categories based on the length of time when memories are stored. One system divides it up as short-term (less than one minute; remembering a telephone number while you dial, for instance), long-term (over a period of years
18、) and very long-term memory (over a lifetime). 3 Short-term memory isnt mastered until about age 7, but after that you never lose it. Long-term memory, however, involves more effort and skill and changes through life. Its not until the early teens that most people develop a mature long-term memory.
19、4 First, we must get information into our heads through learning. Learning strategies can get rusty (生锈的,迟钝的) without constant use. High school and college students, who are forced to repeatedly exercise their long-term memory abilities (at least long-term enough to get them through a final exam), u
20、sually do well on memory tests. The longer you stay in school, the more chance you get to polish your learning skills. Its no wonder that more highly educated people have more effective memory skills throughout life. 5 Although older people in general learn somewhat more slowly than they did when yo
21、unger, a dramatic difference exists between those who stay intellectually active - reading, discussing, taking classes, thinking - and those who do not. Giving the brain a daily workout is just as important as exercising your muscles. Brainwork keeps your learning strategies in shape, and this helps
22、 your memory to function at full capacity. 6 The next part of a healthy long-term memory is retention(保持力,记忆力), the ability to store what you have learned. Memory researchers still do not know whether memories are lost - whether they still exist in the brain nut our mental searching cannot turn them
23、 up, or have disappeared entirely as our brain ages. 7 The third necessity for memory is recall, the ability to mind the memories we have stored. Again, while aging has widely different effects on the recall abilities of different people, research indicates that the older we get, the longer it takes
24、 to recall facts. But slower recall is still recall. In fact, aging does not seem to have any effect on forgetting at all, which takes place at the same rate in younger and older people. 23. Paragraph 3_ 24. Paragraph 4 _ 25. Paragraph 5_ 26. Paragraph 6 _ A. Effects of aging on a persons recall abi
