一、选择题1．--- Jim takes _______ his father.---You mean he is similar _______ his father.A．of ; to B．away; with C．after; to D．care; of C解析：C【解析】句意：-Jim和他的爸爸很像。
-你的意思是他和他的爸爸很相似。
of…的；away离开；after 在…之后；care在意，关心；to 到…；with和…一起。
这个题目考查了两个固定短语，第一个是take after，与…相像；第二个短语是be similar to…与…相似。
故应选C。

【点睛】初中宾语从句的三大考点：1.宾语从句的引导词2.宾语从句的语序及语态3.否定转移，所以考生在做题中遇到宾语从句时，可以从这三个方面入手。
