英语高中的二个填空题

see sb do 表示经常看见某人做某事
see sb doing 表示看见某人正在做某事
由于有always，所以用see sb do
在no sooner than 句型中，动词要用过去完成时，并且要把动词had提到句首形成部分倒装
eg:No sooner had I reached home than it began to rain.

see sb. do sth.一般是指看见动作全过程
see sb. doing sth.是看见动作正在进行也就是一个片段
这里我认为应该是jogging

第二个也可能书上的错，had 后面应该过去分词

We've always seen him (jog) in the morning.
see sb do sth有这种结构的，表示看着整个过程
see sb doing 则强调一瞬间
eg watch him play the violin

They had no sooner (saw) the movie star than the fans cried.
答案错了，过去分词永远是seen

1 因为是过去常常看见，所以不能用ing
2 你可以理解成they had not seen the movie star before the fans cried
