Question

介词后面的动词用什么?

Answer 1

介词后面动词什么形式？
介词后面动词作宾语时一定要用ing形式。

如：

1.He is good at singing .

= He does well in singing .

他擅长于唱歌。

2 .He is looking forward to hearing from his parents .

他正盼望着收到他父母亲的来信。

3. He goes to school without having breakfast every morning .

他每天早上没吃早餐就上学。

拓展（介词的用法）：

1、介词+名词，如：at school，at home,on the desk/wall 。

2、介词+动名词（doing ) 如：He is good at playing football. 3、介词+表示时间的词（固定用法） :in the morning/afternoon / evening ; at noon /night; at six o'clock .

4、介词+人名:如： We are all here except Jim .

5、介词+名词性短语:如：The position is very good except for a few spelling mistakes.
是不是所有介词后面的动词都要加ing形式？
不定式(to),助动词(do).加动词原形。be动词(is.am.are).介词后面加ing形式。还有固定的词组搭配要记住

如果是介词,则其后要用动词的话,肯定用ING形式;如

I am looking forward to your ing.
