小题1:He taught in this school last year.(把last year改为 since last year) He _________ _________ in this school _________ last year.小题2:They didn’t clean the classroom yesterday.（改为被动语态） The classroom _________ _________ yesterday.小题3:We have already returned the books.（改为否定句） We _________ __________ the books ___________.小题4:Rice is grown in China .（划线部分提问）_________ is rice ___________?

Answer 1

小题1:has taught,since 小题2:wasn’t cleaned 小题3:haven’t returned,yet 小题4:Where grown

小题1:把last year改为 since last year，时间由时点变为时段，那么时态也就相应的由一般过去式变为现在完成式。 小题2:被动语态的结构是 Be+动词过去分词，而且句式是一般过去式。 小题3:现在完成式的否定结构是has(have)后面加not, already与肯定句式连用，yet与否定句式连用。 小题4:对地点的提问用疑问副词where。
