使役动词后面跟不带to的不定式 变被动时还原

Question

They won’t let their teacher _______ in that way.

A. to be treated

B. being treated

C. treated

D. be treated
答案是 d
可是不是说被动语态下要还原to吗

Answer 1

They won’t let their teacher ___be treated____ in that way.
不是，这里let并没有变成被动；使役动词转化为被动语态后面动词才还原to；eg.
he made me buy him a paper，转化为被动语态；
i was made to buy him a paper，这下明白了。追问

谢谢 明白了

Answer 2

用不定式作宾补的常用使役动词有 have、make、let 三个，变成被动语态需要恢复 to，如：

〔主动语态〕They won’t make their teacher be treated in that way.
〔被动语态〕Their teacher will be made to be treayed in that way.

不过 let 不能作在被动语态的谓语动词，况且 They won’t let their teacher be treated in that way 本身是主动语态。

Answer 3

They won’t let their teacher _______ in that way.此句是主动语态。
---（被动语态）Their teacher won't be let to be treated in that way by them.
常用的使役动词 make （let， have ）sb do sth 以及感官动词 see （hear ，watch ，listen to ）sb do sth ，改为被动语态时都要还原 to 。例如：
1.We often see him play football .
---He is often seen to play football by us .
2.The boss made his workers work 12 hours a day .
---The workers were made to work 12 hours a day by the boss .追问

Answer 4

这涉及到let的用法：
let+宾语＋动词原形（变成被动语态时，动词原形前要加to）
或者：let+宾语＋be +形容词或过去分词：
Let him go. Let her be happy. Let her be well educated. She is let to be well educated.

Answer 5

let没有被动呀。如果let用了被动，才符合你讲的规则。如：
She let him go home.----He was let to go home.
其它使役动词 如make，have等用法一样
