来源:学生作业帮 编辑:作业帮 分类:英语作业 时间:2024/05/10 13:07:33
及物动词变被动时,动词后面为什么加to 例: was made to do sth?
解题思路: 被动语态还原to的用法。
解题过程:
(一感:feel 二听:listen to,hear 三让:let,have, make 四看:see, look at, watch, notice 半帮助help,) (help sb( to) doto既可以省略也可以不用省略。)在主动句中后跟省略to 的动词不定式。在被动语态中要还原to.。
例如:I hear a boy cry—— A boy is heard to cry.
The eacher made the students do homework.
The students were made to do homework.
最终答案:略
