宾语从句的引导词有特殊疑问词 比如 I don't know what to do.what和do之间有to.但在I don't know what happened to me中,what 和happened没有to .为什么没有to呢?
首先,what to do是一个很常见的固定用法,what是do的宾语,但是以疑问句形式出现what要提前.
其次,what to do中的to do也可以看作是动词的不定式做定语修饰what,也可以看作是整个句子中的宾语补足语成分.what happened to me是一个完整的宾语从句做know的宾语,“What happened to me?”可以独立出来做特殊疑问句.
简而言之,I don't know what to do.是主语+谓语+宾语+宾语补足语的结构.后一句则是主语+谓语+宾语从句的结构.
What should I do.引导宾语从句.还有就是例：I don’t know what to do I don't know what to do中what to do是宾语从句吗? I don't know what to do (改为含有宾语从句的复合句） 请问I don't know what to do next.中的what to do next是宾语从句吗?为什么? I don't know what to do next 改成宾语从句 I don't know what to do next.改为宾语从句 I don't know what to do 英语宾语从句问题,I don't know what to do with the problem.为什么用what?我 貌似歌词中有：i really don‘t know what to do i really don’t know to “I don't what to do.”中的what to do充当什么成分,是宾语从句吗? 有一道题;I really don't know ().A.what to do B.what should I do I understand,but,I don't know what to do?
