　　?　　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:問題問的是：以下哪個(gè)關(guān)于SIV的說法是不真實(shí)的?文章倒數(shù)第二段中提到被觀察的94只帶有SIV的黑猩猩中，有18只得了AIDS。因此C沒有黑猩猩得過AIDS的說法不真實(shí)　　A.earlier than it is supposed to be.　　C.with great agony.　　正確答案: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:問題問的是：第六段中哈恩否認(rèn)什么?第六段中哈恩稱人會(huì)因HIV而得上AIDS，而黑猩猩不會(huì)因SIV而得上AIDS的假設(shè)已經(jīng)不是真的了。因此選C。注意題中denies一詞是否認(rèn)的意思，理解該詞才可能選對　　A.7%.　　C.20%.　　正確答案: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:問題問的是：從文章中我們能了解到什么?ASIV對于黑猩猩沒有影響顯然不對;C感染SIV的黑猩猩生出的孩子不可能夭折。與最后一段最后一句中的higher infant mortality rate即更高的嬰兒死亡率矛盾。DSIV和HIV是完全一樣的也不正確，文中只提到了它們非常相似，但不能說完全一樣。因此選C
