Two groups of scientists demonstrated last week for 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 bloodstream 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 researchers 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
I
解析
此处应填副词修饰动词dropped。根据后句的内容In the majority of cases,the researchers could detect little or no virus two to three weeks later可知,在antibody attack reached full scale的情况下, HIV病毒的水平应是迅速降低的,因此I. abruptly正确。L. lively作副词时意为“轻快地,富有活力地”,不能修饰动词dropped,也与前后文的语境不符。
