为什么是who told you,而不是who did tell you?还有,why的问题到底要怎么用阿?

问题描述:

为什么是who told you,而不是who did tell you?还有,why的问题到底要怎么用阿?
是why didn't you go to work 还是why you didn't go to work?

who在这句话中做的是主语,所以不用加did,如果加了did,就是提问宾语,即“你告诉谁了?”而不是主句的“谁告诉你的?”
而第二句则是特殊疑问句,主语和宾度都不缺,用完全倒装形式,即“why you didn't go to work?”
希望能对您有所帮助
