题目内容
15.The number of smokers,__________ is reported,has dropped by 17percent in just one year.( )A. | it | B. | which | C. | what | D. | as |
分析 正如所报道的那样,吸烟者的数量仅一年就减少了17%.
解答 答案D.这是含有非限制性定语从句的复合句,空缺的词为关系代词,故排除A、C.as引导的非限制性定语从句位置灵活,可以放在句首、句中、句末.本题容易误选B项,把the number of smokers看成是先行词,这里的关系代词指代的是the number of smokers has dropped by 17percent in just one year这一整句话,而且"as is reported"是常用表达法,故选D.
点评 对于关系代词的选择,要分析句子成分,还要结合关系代词本身的用法,加以选择和判断.
