专业英语八级（阅读）模拟试卷207
选择题
(1)That smoking causes lung cancer is well established. But what causes smoking? This is the question at the heart of a study published in Nature by a group of researchers who work at deCODE, an Icelandic genomics company. They do not, quite, answer it. But they do think they have the answer to the related question of why some smokers smoke in moderation whereas others are rarely found without a fag in their hands—and thus why some people are, genetically speaking, more susceptible to lung cancer than others.
(2)That answer lies in part of human chromosome 15, and depends on what is known as allele T of SNP rsl051730. A SNP, or single-nucleotide polymorphism, to give its full name(the short version is pronounced \\
1.All of the following have enough evidence EXCEPT that _____.(C)
A. lung cancer is related to chromosome 15
B. lung cancer is related to genetics
C. smoking is genetically decided
D. smoking causes lung cancer
解析：第4段倒数第2句提到基因诱导吸烟，而最后一句却用it might be wrong来否定这个说法，且第5段第2句提到基因变异与个人吸烟习惯没有直接关系，故选C。第4段首句的胸腺嘧啶的变异和吸烟者发生肺癌的机会呈正相关；而根据第2段首句可知，胸腺嘧啶存在于chromosome 15，也属于基因变异这一系列的事实，可推出A、B符合文意；D与第4段倒数第2句中的smoking promotes cancer相符。
2.The results of the study done by Paul Brennan and Christopher Amos _____.(B)
A. have shown a completely contradictory situation with the study done by deCODE
B. suggest that the situation may be more complex than deCODE has identified
C. show that rs8034191 instead of rs1051730 is related to the susceptibility to lung cancer
D. smoking behavior is modified by genetic variations in the region of chromosome 15
解析：第5、6段提到Paul Brennan和Christopher Amos所做的研究与deCODE公司结果的一些不同之处和相似之处，并在第6段末句总结得出，实际情况可能更加复杂，B符合此意，故正确。A中的completely太绝对：C中的instead of与第6段倒数第2句中的involved as well不符；第5段第2句中的rather than否定了…modifying his smoking behaviour，故D错误。
3.The current conclusions drawn from the studies have been _____.(C)
A. disappointing
B. frustrating
C. enlightening
D. comprehensive
解析：最后两段对原文提到的研究所得的结论做了总结评价，其中倒数第2段首句提到这些研究既puzzling又intriguing，而末段首句又提到这些研究raises interesting issues，且该段第2句又说到对问题更深入理解的一天“近在咫尺”。由此可知，作者认为这些研究的结果是很具启发性的，故选C。A和B的disap-pointing和frustrating属于贬义。通读全文可知作者并未在文中表达出贬义的感情色彩；文中提到了两个产生对立结论的研究，并表明还有问题没有确定，可见研究的结论不全面，故D“综合性的，全面的”不对。
4.Which of the following is INCORRECT about the study of genetics?(A)
A. The different methods adopted have led to the different conclusions that researchers drew.
B. The two groups of researchers have provided evidence in their favor respectively.
C. The role of genetics in smoking and lung cancer has yet to be studied and confirmed.
D. The development of genetic testing has made studies on genetics and lung cancer easier.
解析：第7段首句确实提到了布伦南和阿莫斯教授均采用了和deCODE公司不同的研究方法，但第6段首句提到他们均确定rs1051730是一个重要的单核苷酸多态性结构，这一点与deCODE公司观点一致，说明两个研究也存在相同之处，故A中的第二个different表述不对，因此选A。
(1)When outsourcing company Keane Inc. hired Jyoti Taneja 10 months ago to work in its Gurgaon, India, offices, her parents were worried. The 22-year-old Ms. Taneja would be taking calls from American customers of U.S. health-insurance companies, finishing her shift at 2:30 a.m.
(2)Hoping to reassure their young hire\’s parents about her safety, her supervisors at Keane paid several visits to Ms. Taneja\’s family home in nearby New Delhi.
