Choose the best word(s) for each numbered blank and mark A, B, C or D. (10 points) 1 【正确答
20、案】 A【试题解析】 考查语法结构。解答此题需结合第二个空。由第二个空的四个选项可知考查的是及物动词的含义,故此处所填的词引导表语从句,且做第二个空处动词的宾语,符合题意的只有 Awhat。how,why, when 均不能在从句中作宾语。2 【正确答案】 B【试题解析】 考查动词辨析。从此题所在的句子的前后内容可以判断出,That is_中的 That 是指第一句话的内容,即朋友与我们在基因上的相关性,很显然是研究得出的结论。conclude 意为“作结论”,符合题意,故答案为 B 项。defended“辩护,防护”,withdrawn“撤销;收回”,advised“建议”,均不符合题意。3
21、 【正确答案】 D【试题解析】 考查固定搭配。本句中的主句意为:这项研究是一个基于 1 932 个独特实验对象的全组基因分析。conduct analysis on 即 conduct sthon 为固定搭配,意为“基于”,故选 D 项。4 【正确答案】 C【试题解析】 考查动词辨析。该空格所在的句子是 which 引导的定语从句,修饰study,其大意为:对几对基因不相关的朋友和基因不相关的陌生人进行_。因为“研究”的内容是关于朋友间基因上的相关性问题,所以完整的意思应该是:对几对基因不相关的朋友和陌生人进行比较。故答案为 Ccompared 。separated“使分离,使分开”,soug
