Two groups of scientists demonstrated last week for the first time that the body launches a massive, effective counterattack 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【C1】______stages of the disease. The researchers should be【C2】______— and more than a bit of luck. After all, to study someone at the beginning of a relatively【C3】______phase of the HIV infection, they had to find people who did not yet realise they had contracted the virus. It【C4】______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【C5】______. Such signs, which usually clear up in their own, can easily be【C6】______as a bad flu. In order to identify seven young men suffering from a primary HIV infection, the researchers took this project by【C7】______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【C8】______growth of virus in the men’s blood streams. Each litre 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【C9】______. Once the antibody attack reached full scale in the seven test subjects, the level of HIV in the bloodstream dropped【C10】______. 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.
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] 【C8】
选项
答案
M
解析
空前的an表明,此处应填一个以元音音素开头的形容词。O)exhausting(令人疲惫不堪的)不能用来说明HIV病毒的生长情况,因此应排除。M)explosive意为“爆炸性的”,修饰growth时可以表示生长繁殖的速度极快,故答案为M)。
