职称英语理工类阅读理解的精选练习题

  AIDS-like Disease Found in Monkeys  An international group of scientists has found evidence that wild chimpanzees infected with Simian Immunodeficiency Virus - once considered harmless to the apes - can develop a deadly AIDS-like syndrome. Researchers say the discovery could lead to new treatments for HIV, the virus that causes AIDS in humans.  But researchers studying a large group of wild chimpanzees in Gombe National Park in Tanzania report SIV-infected chimps experienced immune system failure and were much more likely than uninfected apes to die prematurely.  Hahn says it significant that chimps can develop AIDS just like people infected with HIV-1, one of two viral strains that jumped the species barrier to humans.  Researchers observed 94 SIV-infected and uninfected chimps at the start of the study a decade ago. Eighteen of the chimps developed AIDS, and seven died of the disease.  1.Which of the following statements is NOT true about SIV according to the passage  B.It has long been thought to be the original source of HIV.  D.SIV can cause AIDS in apes  解析:问题问的是:以下哪个关于SIV的说法是不真实的?文章倒数第二段中提到被观察的94只带有SIV的黑猩猩中,有18只得了AIDS。因此C没有黑猩猩得过AIDS的说法不真实  A.earlier than it is supposed to be.  C.with great agony.  正确答案:A  3.In Paragraph 6, Hahn denies  B.SIV is actually the source of HIV-1.  D.Chimps infected with SIV can develop AIDS  解析:问题问的是:第六段中哈恩否认什么?第六段中哈恩称人会因HIV而得上AIDS,而黑猩猩不会因SIV而得上AIDS的假设已经不是真的了。因此选C。注意题中denies一词是否认的意思,理解该词才可能选对  A.7%.  C.20%.  正确答案:A  5.We can learn from the passage that  B.chimps infected with SIV are at a higher risk of death than the others.  D.SIV and HIV are exactly the same thing  解析:问题问的是:从文章中我们能了解到什么?ASIV对于黑猩猩没有影响显然不对;C感染SIV的黑猩猩生出的孩子不可能夭折。与最后一段最后一句中的higher infant mortality rate即更高的婴儿死亡率矛盾。DSIV和HIV是完全一样的也不正确,文中只提到了它们非常相似,但不能说完全一样。因此选C
