改错：Did you watched TV last night?We usually doesn't have clas on Saturday.
She didn't her homework yesterday.Jane hasn't do her work.
答
1 watched -> watch （ 助动词DID 后的动词要用原形）2 doesn't -> don't 因为主语是复数3 didn't -> didn't do （ 原句缺少谓语动词）4 do -> done ( 现在完成时的结构是；have /has +动词的过去分词）如果不明白,...改错：She didn't her homework yesterday. Jane hasn't do her work.
