再问： I ____(hear) him ___(sing) this song at that time.she ____(see)____(take) a walk by me yesterday. she ____(see)____(take) a walk by me this time yesterday. they ____(notice)____(hang) out two hours ago. I _____(often tell) ____(listen) to the teacher carefully in class.my mother often ———（make）me ——（do） 12 hours one day. 帮一下忙
再答： I was hearing him sing this song at that time.感觉这道题有歧义，就看你怎么理解at that time 了 she was seen take a walk by me yesterday. she was seen taking a walk by me this time yesterday.这两道题我也觉得没什么意义，本来我上一道填的是taking，但为了和这道题的this time 所区分才选成take。语法上来讲都是没错的，重要的是你能理解see sb. do sth.和see sb. doing sth.的区别就行了 they were noticed hanged out two hours ago.这里hang我理解成了吊死。 I am often told to listening to the teacher carefully in class.my mother often makes me do（do what？）12 hours one day.
