3.We still don't know the exact time for the first human being .( )A. | to have been cloned | B. | being cloned | ||
C. | having been cloned | D. | to be cloned |
分析 我们仍旧不知道人类首次被克隆的准确时间.
解答 答案:B.根据句子结构可以知道the first human being .( 做for 的宾语,介词的宾语用doing,而且human being和clone之间是被动关系,所以用doing的被动式,因此答案是B.其他选项中C项表示完成被动,只做状语.
点评 考查动名词做宾语.现在分词有几种形式:一般式doing,表示其动作与谓语动词的动作同时发生;
完成式 having done 表示其动作在谓语动词的动作之前完成;
被动式being done表示其逻辑主语为现在分词动作的承受者
