Question

什么时候动词在没有be动词下会成为动词ing形式,我只知道动词用在开头则要用动词ing,还要什么情况可以?

Answer 1

1.好多词的后面需用动词-ing 形式 例如

finish doing 完成做某事,start doing 开始做某事 ,stop doing 停止做某事

,forget doing 忘记做过某事 ,practise doing 联系做某事 ,consider doing 考虑做某事

等等

2.非谓语 即句子主语和分词成逻辑上的主谓关系

He was exhausted by his work,threwing himself on his bed.
