you must return the books to the library on time .把这句子变成被动语态 并且为什么
特别是to the library on time 这些单词的位置 放置的规律
The books must be returned to the library on time (by you).
1.简单来说,被动语句的变化和中文一样.
如：我打你.--- 我被你打.
你必须及时将书交还图书馆.--- 书必须被及时交还给图书馆.
所以我们变化的被动句中：the books被提到句首.
2.A do B --- B be done by A
被动语态中谓语动词的被动由be +done（be动词+过去分词）构成.
本句中,must return --- must be returned
3.被动句中的“被谁”在英语中要放在谓语动词之后.如果还有时间地点等很多成分在后,又不知道到底怎么分析谓语在哪里,就放在句末.如果这个by sb.的sb是代词,还可以被省略去.
希望可以帮到您.
再问： he may ask her for help. 这个呢 怎么变 for help 放到哪里
再答： She may be asked for help by him. 这个原句的ask her for help是一体的。您可以通过中文理解。 他向她寻求帮助。 她（被他）寻求帮助。---这里的寻求帮助在中文中就在一起，没有被分割开。在英文中也是一样的。
