题目内容
11.I don't know ______he will come tomorrow.______ he comes,I'll tell you.( )| A. | if;Whether | B. | whether;Whether | C. | if;That | D. | if;If |
分析 我不知道他明天是否来.如果他来我就告诉你.
解答 答案:D.根据he will come tomorrow放在动词know 之后,故本句是一个宾语从句;根据句意,本句应填"是否"if或whether.又根据第二个句子的 结构可知,本句 应是以if 引导的条件状语从句,if 是"如果"的意思,而whether没有"如果"的意思.故选D.
点评 本题主要考查if引导的两种从句,做题时应注意区分两种从句的不同用法.
