Two groups of scientists demonstrated last week fox the first time that the body launches a massive, effective counter-attack on the virus soon after infection of HIV begins. If doctors can figure out how to reproduce that early, powerful immune response, they might be able to develop better treatments to (47)______ stages of the disease.
The researchers should be (48)______—and more than a bit of luck. After all, to study someone at the beginning of a relatively (49)______ phase of the HIV infection, they had to find people who did not yet realize they had contracted the virus. It (50)______ that at least a third of HIV-infected people develop a fever or a severe sore throat within a few weeks to months after first (51)______ Such signs, which usually clear up in their own, can easily be (52)______ as a bad flu. In order to identify seven young men suffering from a primary HIV infection, the researchers took this project by (53)______ in hospital emergency rooms and talking to colleagues.
Using advanced laboratory tests that had been developed only in the past few years, both sets of scientists discovered an (54)______ growth of virus in the men’s blood streams. Each liter of the men’s blood contained as many as 10 million infectious viruses.
Within days after the virus burst, the researchers measured a rapid increase in the blood-stream of the number of anti-HIV antibodies(抗体). These Y-shaped bits of protein sought out the virus and targeted it for (55)______. Once the antibody attack reached full scale in the seven test subjects, the level of HIV in the bloodstream dropped (56)______. In the majority of cases, the re-searchers could detect little or no virus two to three weeks later. In other words, the normal immune system can shut down the AIDS virus. Now researchers must figure out exactly how the body puts together this early effective defense—and how the virus manages, years later, to avoid it.
Word Bank:
A. destruction I. abruptly
B. interrupt J. segregation
C. impair K. testifies
D. residing L. lively
E. misdiagnosed M. explosive
F. exemplified N. silent
G. persistent O. exhausting
H. exposure
[br]
选项
答案
E
解析
结合空前的be和空后的as推断,空中应填入动词的过去分词构成被动语态。综合本句和前句的内容可知,初次感染HIV后的症状与感冒症状很相似,而且这些症状经常会自动消失。由此推断,这些症状应该很容易被误诊为感冒,故选项E. misdiagnosed为答案。be exemplified后通常接by引导的介词短语,而不接as引导的短语,因此排除F。
