Question

after completing和after completed意思有甚麼分别呢
1.After completing the work,I play with friends
2.After completed the work,I play with friends
两句的用法都正确吗?意思有甚麼不同呢

Answer 1

1正确,2错
after后面到底用表示主动的现在分词还是表示被动的过去分词,要看after的逻辑主语是人还是物,after后非谓语结构的逻辑主语（即从意义上讲的主语而非真正主语,因为不是从句没有第二个主语的）就是后面主句的主语,既然后面主句的主语是I（我）,人,我自己完成工作,因此用主动的现在分词
另外以物作逻辑主语的例句供参考：
After completed,the project was put into use soon.项目完工后立即投入了使用.
