I have finished my homework for two hours/I have joined the army since 2005/
I have arrived in London for two days.哪里错了,请告知,

这三个句子中的动词finish,join和arrive 都是瞬间动词,动作完成即结束,不能持续.后面不能跟表示时间段的时间状语.
改为延续性动词 have been
一般有两种更改方式
I finished my homework two hours ago.
I joined the army in 2005./ I have been in the army since 2005.
I arrived in London two days ago./I have been in London for two days.

I have finished my homework for two hours/I have joined the -I have finished my homework.-When ( )you( )it?-Two hours ag I have finished my homework two hours ago.哪里错了 I have finished my homework I have been over my homework for three hours I will have finished the homework by the time my I have finished my homework.反义疑问句 A:I have finished my homework ---I have finished my homework already, mum. I have finished my homework now. I (have finished) my homework now.选择题 I have finished my homework before I leave home.
