New Attempts to Eradicate AIDS Virus

A high-profile attempt to eradicate the AIDS virus in a few patients continues to show promise.

But researchers won't know for a year or more whether it will work, scientist David Ho told journalists this Wednesday for the Fourth Conference in Viruses and Infections.

\AIDS Research Center, New York.

The study involves 20 people who started combinations of anti-HIV drugs very early in the course of the disease, within 90 days of their

infections. They've been treated for up to 18 months. Four others have dropped out because of side effects or problems complying with the exacting drug system.

The drugs have knocked the AIDS virus down to undetectable levels in the blood of all remaining patients. And, in the latest development,

scientists have now tested lymph nodes and semen from a few patients and found no virus reproducing there, Ho says. \in mind that undetectable does not equal absent,\

Ho has calculated that the drugs should be able to wipe out remaining viruses — at least from known reservoirs throughout the body — in two to three years. But the only way to prove eradication would be to stop the drugs and see if the virus comes back. On Wednesday,' Ho said he wouldn't ask any patient to consider that step before 2 years of treatment. And he emphasized that he is not urging widespread adoption of such early, aggressive treatment outside of trials. No one knows the long-term risks. But other scientists are looking at similar experiments. A federally funded study will put 300 patients on triple-drug treatments and then see if some responding well after six months can continue to suppress the virus on just one or two drugs, says researcher Douglas Richman of the University of California, San Diego. Some patients in that study also may be offered the chance to stop therapy after 18 months or more, he says.

According to the passage, the attempt to eradicate the AIDS virus ______. A continues to be hopeful

B will be successful in a year C will be successful in future D will stop being hopeful 【正确答案】：A

【本题分数】：3.0分

【答案解析】

[解析] 利用题干中的核心词“the attempt”作为答案线索，同时注意利用备选项中的核心词 hopeful和successful，这样发现答案相关句：Ahigh-profile attempt to eradicate the AIDS virus in a few patients continues to show promise(与A中的hopeful呼应)．这个句子的意思是“为消除一些病人身体中的AIDS病毒所做的尝试一直显示出希望”，根据这句话的内容判断A(一直显现出希望)是答案。 第2题

Which is NOT true about the study?

A There are 20 patients involved in the study. B The patients have used several anti-HIV drugs. C The patients have been treated for up to 18 months. D 16 patients did not go through the whole study. 【正确答案】：D

【本题分数】：3.0分

【答案解析】

[解析] 这是“是非判断”题，对于这类问题在解题过程中必须充分利用备选项的结构、句意和用词特点(本题中所给的备选项中出现了病人人数和时间)，因此注意文章中涉及病人人数和时间的句子，这样找到答案相关句：The study involves 20 people(说明A正确：有20个人参与实验)who staged combinations of anti-HIV drugs(说明B正确：在疾病早期阶段使用过集中抗HIV药品)very early in the course of the disease，within 90 days of their in

fections．They've been treated for up t0 18 months．，(证明C正确)Four others have dropped out(该结构说“另外有四个人退出”，因此参加完整个实验的有16人，因此D错误)because of side effects or problems complying with the exacting drug system．drop out v意为“不参与，离去，放弃”。 第3题

What do Ho's words \in mind that undetectable does not equal absent\mean?

A AIDS virus can exist in the blood without being detected. B AIDS virus is undetectable in the blood. C NO AIDS virus can be detected in the blood. D No virus found in the blood means no AIDS. 【正确答案】：A

【本题分数】：3.0分

【答案解析】

[解析] 首先找出引语所在的上下文，并结合该引语的本意(记住不能检测出来并不等于没有)，判断答案A正确。 第4题

How could we prove that the drags have wiped out the remaining viruses? A By using up all the drugs at once. B By waiting for the virus to die slowly.

C By asking the patients' feeling about the disease. D By stopping the drugs to see if the virus comes back. 【正确答案】：D

【本题分数】：3.0分

【答案解析】

[解析] 该题可直接借助常识判断，也可以借助原文：利用题干中的核心短语“wiped out”’作为答案线索，这样发现答案相关句：He has calculated that the drugs should be able to wipe out remaining viruses—at least from known reservoirs(储主) throughout the body—in two to three years．But the only way to prove eradication(与wiped out是近义词)would be to stop the drugs and see if the virus comes back．该句的意思是“证明是否彻底消灭了病毒的唯一方法就是观察停药后病毒是否会卷土重来。”，因此D是正确答案。wipe out v．意为“消灭，垮台”。 第5题
