使役动词的用法知识点12

Ron：Look at those men, what were they?

Jennifer：They were slaves. They were sold to the slave owners, and they were made to do lots of work every day.

Ron：Poor men! What about those women?

Jennifer：They were geishas(艺伎).

Ron：What？

Jennifer：They were made to dance or sing for the guests after they had been trained for a long time.

Ron：Unbelievable!

Molly：老师，我发现Ron和Jennifer的对话中有两处错误。

They were made to do lots of work every day.

他们被迫天天要干好多活。

They were made to dance or sing for the guests.

她们被迫给客人唱歌跳舞。

make是使役动词，后面应该接的是不带to的不定式吧！

Teacher：Good point！使役动词make，have，let常见的句型是make/let/have sb. do sth.，你再对比下这两个句子，是不是不符合这个句型呢？

Molly：是的呢。这两个句子的made前都有be动词were。（效果：在例句上作效果）

Teacher：Right.所以这两个句子是被动语态结构。(文字效果：使役动词make/let/have的被动语态)在主动语态的句子中，使役动词后常使用省去to的不定式作宾语；而在被动语态中，则需还原不定式to。

也就是说make/let/have sb. do sth.的被动语态是 sb. is made/let/had to do sth.,其中在使役动词let的被动语态中，to可以省略，即sb. is let do sth.Molly：好的，我懂啦！

Teacher：那你试试把这个句子改写成被动语态吧。

She always lets me do homework for her.

她经常让我给她写作业。

Molly：I was always let do homework for her.

我经常被弄得给她写作业。

Teacher：Good job！除此之外有一些感官动词在变成被动语态时，也需要将不定式to还原。比如我们之前讲的“一感二听三让四看半帮助”。

一感：feel

二听：hear、listen to

三让：make、let、have

四看：see、watch、notice、look at

半帮助：help

Molly，你能举个例子吗？

Molly：可以啊。

主动语态：I saw her play basketball yesterday.

我昨天看见她打篮球了。

被动语态：She was seen to play basketball by me yesterday.

她昨天被我看见打篮球了。

Teacher：Well done！Habit is second nature.习惯成自然。不管是在学习还是生活上，希望大家都能养成良好的习惯哦。
