17、ranslator. The translator must have an excellent, up-to-date knowledge of his (26) language, which will be his mother tongue or language of (27) use, full facility in the handling of his target language, and knowledge and understanding of the latest subject-matter in his field of (28) . In addition
18、to this, it is desirable that he should have an (29) mind, wide interests, a good memory and the ability to grasp quickly the basic principles of new developments. He should be willing to work on his own, often at high speeds, but should be humble enough to (30) others should his own knowledge not a

He should be able to type quickly and (31) and, if he is working mainly for publication, should have more than a nodding (32) printing techniques and proof-reading. If he is working basically as an information translator, let us say, for an industrial firm,
20、he should have the flexibility of mind to enable him to (33) one source language to another, as well as from one subject matter to another, since this ability is frequently required of him in such work. (34) the nature of the translators work, i.e. the processing of the written word, it is, strictly

If he does speak them, it is an advantage rather than a hindrance, but this skill is in many ways a (35) that he can do away with.（分数：71.00）填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_填空项 1:_九
22、、Part Reading Compr(总题数：0，分数：0.00)十、Section A(总题数：1，分数：35.50)Recently, book publishers got some good news. Researchers gave 852 disadvantaged students 12 books to take home at the end of the school year. They did this for three (36) years.Then the researchers looked at those students test scores. Th
23、ey found that the students who brought the books home had (37) higher reading scores than other students. These students were less (38) by the “summer slide“the decline that especially afflicts lower-income students during the vacation months. In fact, just having those 12 books seemed to have as mu
24、ch (39) effect as attending summer school.This study, along with many others, (40) the tremendous power of books. We already knew, from research in 27 countries, that kids who grow up in a home with 500 books stay in school longer and do better. This new study suggests that introducing books into ho
25、mes that may not have them also produces significant educational gains.Recently, Internet experts got some bad news. They examined computer use among a half-million 5th through 8th graders in North Carolina. They found that the spread of home computers and high-speed Internet access was associated w

He (44) a pile of research showing that the multi-distraction, hyperlink world degrades peoples abilities to engage in deep thought or serious contemplation.Carrs argument has been challenged. His critics point to (45) that suggests

Researchers report that a spinal fluid test can be 100 percen
30、t accurate in identifying patients with significant memory loss who are on their way to developing Alzheimers disease. Although there has been increasing evidence of the value of this and other tests in finding signs of Alzheimers, the study, which will appear Tuesday in the Archives of Neurology, s
31、hows how accurate they can be. The new result is one of a number of remarkable recent findings about Alzheimers.B. After decades when nothing much seemed to be happening, when this progressive brain disease seemed untreatable and when its diagnosis could be confirmed only at autopsy, the field has s
32、uddenly woken up.C. Alzheimers, medical experts now agree, starts a decade or more before people have symptoms. And by the time there are symptoms, it may be too late to save the brain. So the hope is to find good ways to identify people who are getting the disease, and use those people as subjects
33、in studies to see how long it takes for symptoms to occur and in studies of drugs that may slow or stop the disease.D. Researchers are finding simple and accurate ways to detect Alzheimers long before there are definite symptoms. In addition to spinal fluid tests they also have new PET scans of the
34、brain that show the telltale amyloid plaques that are a unique feature of the disease. And they are testing hundreds of new drugs that, they hope, might change the course of the relentless brain cell death that robs people of their memories and abilities to think and reason. “This is what everyone i
35、s looking for, the bulls-eye of perfect predictive accuracy,“ Dr. Steven DeKosky, dean of the University of Virginia medical school, who is not connected to the new research, said about the spinal tap study. Dr. John Morris, a professor of neurology at Washington University, said the new study “esta
36、blishes that there is a signature of Alzheimers and that it means something. It is very powerful.“E. A lot of work lies ahead, researchers saymaking sure the tests are reliable if they are used in doctors offices, making sure the research findings hold up in real-life situations, getting doctors and
37、 patients comfortable with the notion of spinal taps, the method used to get spinal fluid. But they see a bright future. Although the latest PET scans for Alzheimers are not commercially available, the spinal fluid tests are.F. So the new results also give rise to a difficult question: Should doctor
38、s offer, or patients accept, commercially available spinal tap tests to find a disease that is yet untreatable? In the research studies, patients are often not told they may have the disease, but in practice in the real world, many may be told.G. Some medical experts say it should be up to doctors a
39、nd their patients. Others say doctors should refrain from using the spinal fluid test in their practices. They note that it is not reliable enoughresults can vary by laband has been studied only in research settings where patients are carefully selected to have no other conditions, like strokes or d
40、epression, that could affect their memories. “This is literally on the cutting edge of where the field is,“ Dr. DeKosky said. “The field is moving fast. You can get a test that is approved by the F.D.A., and cutting edge doctors will use it.“ But, said Dr. John Trojanowski, a University of Pennsylva
41、nia researcher and senior author of the paper, given that people can get the test now, “How early do you want to label people?“ Some, like Dr. John Growdon, a neurology professor at Massachusetts General Hospital who wrote an editorial accompanying the paper, said that decision was up to doctors and
42、 their patients.H. Sometimes patients with severe memory loss do not have the disease. Doctors might want to use the test in cases where they want to be sure of the diagnosis. And they might want to offer the test to people with milder symptoms who want to know whether they are developing the devast
43、ating brain disease.I. One drawback, though, is that spinal fluid is obtained with a spinal tap, and that procedure, with its reputation for pain and headaches, makes most doctors and many patients nervous. The procedure involves putting a needle in the spinal space and withdrawing a small amount of
44、 fluid. Dr. Growdon and others say spinal taps are safe and not particularly painful for most people. But, he said, there needs to be an education campaign to make people feel more comfortable about having them. He suggested that, because most family doctors and internists are not experienced with t
45、he test, there could be special spinal tap centers where they could send patients.J. The new study included more than 300 patients in their 70s, 114 with normal memories, 200 with memory problems and 102 with Alzheimers disease. Their spinal fluid was analyzed for amyloid beta, a protein fragment th
46、at forms plaques in the brain, and for tan, a protein that accumulates in dead and dying nerve cells in the brain. To avoid bias, the researchers analyzing the data did not know anything about the clinical status of the subjects. Also, the subjects were not told what the tests showed.K. Nearly every
47、 person with Alzheimers had the characteristic spinal fluid protein levels. Nearly three quarters of people with mild cognitive impairment, a memory impediment that can precede Alzheimers, had Alzheimers-like spinal fluid proteins. And every one of those patients with the proteins developed Alzheime
48、rs within five years. And about a third of people with normal memories had spinal fluid indicating Alzheimers. Researchers suspect that those people will develop memory problems.L. The prevailing hypothesis about Alzheimers says that amyloid and tau accumulation are necessary for the disease and that stopping the proteins could stop the disease. But it is not yet known what happens when these proteins accumulate in the b
