The one thing I hate to do is ___to bed before I feel tired.

问题描述:

The one thing I hate to do is ___to bed before I feel tired.
A go B to go C went Dgone 可前面不是讲“不定式在系动词be后做表语时,如果主语部分有实义动词do,不定式就可省去to" (无敌英语精装版206页7题)
为何不选A

___to bed before I feel tired.
这句是个从句,可化为THAT ___to bed before I feel tired.
在这个里面就要有TO了
我也是根据了一点语感
