第二句应该是:
I don't know how to do it .
how 是副词,不能作 to do 的宾语,所以必须加 it 作宾语.
I don't know what to do .中 what 是 代词,可以作宾语.
应该是I don't know how to do it
后面加个it,how是怎么做这件事能详细点不 有的模糊 谢谢虽然有点迟了,而且采纳的那个答案也好专业的样子,不过有始有终,我还是给自己补充下。个人意见,仅供参考
how 是怎样,所以是how to do the thing(怎样做这件事),it是代词,指代the thing.
what to do 是做什么,后面不需要it...
