解题思路： 如下
解题过程：
1、I saw Jack helping a blind man cross the street yesterday afternoon.(改为被动语态) Yesterday afternoon Jack was seen helping a blind man cross the street 2、You can renew the book for another week(改为被动语态) The book can be renewed for another week. 3、Rice is groen in the south of China.（用people 做主语，改为被动语态） 同学你好，此题应该是改为主动语态。 People grow rice in the south fo China. 4、Your homework must be handed in tomorrow morning.(改为被动语态) 同学你好，此题应该是改为主动语态。 You must hand in your homework tomorrow morning.
被动语态的结构为“助动词be＋及物动词的过去分词（p．p）”。被动语态的不同时态是通过be的时态变化来表示的，其人称和数方面应与主语保持一致。其具体变化为： 一般现在时：am／is／are＋p．p． 一般过去时：was／were＋p．p． 一般将来时：shall ／will be ＋p．p． 现在完成时：have ／has been ＋p．p． 现在进行时：am／is／are＋being＋p．p． 过去将来时：should ／would be ＋p．p． 含情态动词的被动结构：情态动词＋be＋p．p． 注意： 在see, let, make, hear, watch 等动词之后，作宾语补足语的动词不定式不带to，但在变为被动语态时，则一定要加上to。 如：1. We saw them play football just now. l They were seen to play football just now. 2. We often hear her sing in English. l She is often heard to sing in Englis 3. The teacher made the little boy stand in the classroom. The little was made to stand in the classroom by the teacher.
