I don't know _________he will come or not tomorrow.________he come,I will tell you.
a.if If b.if Whether c.whether If d.whether Whether
这里第一个句子
I don't know _________he will come or not tomorrow
这里填whether.这句是whether引导宾语从句.翻译为“是否“.
这里不用if 的原因是后面有个”or not“,一旦你看到它,就知道只用whether.
宾语从句中,主句为一般现在时,从句根据句意,可以使用任意一种时态.所以这里可以用将来时.
句子意思是:我不知道他明天是否要来.
第二句,
____he come,I will tell you.
这句是条件状语从句.状语从句有个规律叫做 ”主将从现“.
即 主句将来时,从句 一般现在时.这里的主句是 I will tell you.所以前面是一般现在时.
用if.这里的if 翻译为”如果“.
句子意思是:如果他来了,我就告诉你.
