after doing还是do

文/无所谓
专题:

after为介词,介词后接doing,做宾语,介词后面如果用动词,只能用动词的现在分词形式,即doing。具体内容跟小编一起来看看吧。

after后面加doing还是do

“after doing”。after为介词,根据介词后面如果要加动词,只能用动词的现在分词形式,所以after后面不能用do,只能用doing。

例句:You may have a rest after doing your homework.做完作业后你可以休息一会儿。

“after doing”成立,但“after do”不成立。其关键点在于:after为介词,介词后面如果用动词,只能用动词的.现在分词(动名词)形式,即doing作做宾语。
