肯定句改为疑问句和否定句后,是不是要把里面的动词还原呢?这块的规则谁能详细说下呢,
我看有些变回去还原了,有些保持了原来的状态,具体的规则是怎样的呢,感觉有点混淆啊.

Answer 1

肯定句改为疑问句和否定句,只有谓语动词是行为动词的一般现在时和一般过去时的句子中,动词需要用原形,其他时态只需要把助动词 提前变疑问句,在助动词后加not 变否定句,
eg .He likes reading .He doesn't like reading .Does he like reading
He gave me a book .He didn't give me a book .Did he give you a book?
He will leave here .He will not leave here .Will he leave here
He has been here for a while .He hasn't been here for a while .Has he been here far a while
He is reaing a book .He isn't reading a book .Is he reading a book?
