各位老师,我就想确定一下,第一句是对的,对吧,
What I'm not sure about is when you don't do it
What I'm not sure about is when you not do it
因为肯定式的时候去掉了助动词do,否定式我不太确定,
What I'm not sure about is when you don't do it. 正确
What I'm not sure about is when you not do it. 错误
这是所谓的“假拟分裂句”,强调when从句。不强调的普通句式为:
I'm not sure (about) when you don't do it.
对方总是做某事(you always do it). 所以说话人不能确定对方什么时候不做此事。独立的特殊问句为:When don't you do it?
原第二句when从句否定没有用操作词为语法错误。
