英语中的句子并不总是遵循着主语+动词+宾语的规律。跟我们的母语一样，有时主语什么也不做，但是却导致别人去做些事情。所以，逻辑上我们把导致别人行动的动词叫使役动词。下面小编告诉你初中英语使役动词用法，大家一起来看看吧!
初中英语使役动词用法:
最常见的使役动词有:let / make / have / get.
规则其实很简单
let+ 名词 + 动词原形
My neighbour lets his children play computer games when they are at the dinner table!
make + 名词 +动词原形
I never made my children do homework. I believed that it was their responsibility.
I make my dog sleep outside at night. I make him eat outside too.

make+ 名词 + 形容词
严格意义上讲，如果名词后面接了形容词，这不算使役动词。但是我们要注意这个结构，与使役动词后面加过去分词是一样的。看下面的例句:
Chocolate makes people happy!
The news on TV makes some people depressed.
Exams make most people nervous.
Shopping makes me tired.
chocolate, TV news, 还有exams影响了情感. Depressed 和 tired 是ed结尾的形容词/过去分词
have+ 名词 + 动词原形
I have the doctor check my blood pressure every visit.
I always have my daughter cook dinner on the days I see the doctor.
have+ 名词+ 过去分词
I had my teeth whitened last week.
My husband will have his car serviced tomorrow.
get+名词 + 过去分词
I get my hair cut once a month.
Linda gets her house cleaned every week.
get + 名词 + 不定式
A lot of parents are trying to get their children to playmore sport.
How can we get childrento eatmore vegetables?
使役动词make用法说明:
1. 后接不定式的复合结构作宾语时，不定式不能带 to;但是，若make为被动语态，则不定式必须带to。如:
Though he had often made his little sister cry, today he was made to cry by his little sister. 虽然他曾经常把他小妹妹弄哭，但今天他被他小妹妹弄哭了。
注意，若make不表示“使”，而表示其他意思则情况不同，比如下面两句，make后的不定式不是宾语补足语，而是目的状语:
We make candles to give light. 我们做蜡烛照明。
He made a box to put his money in. 他做了个盒子来装钱。

2. 其后除可接不带to的不定式作宾语补足语外，还可以接以下成分:
(1) 接过去分词作宾语补足语。如:
He tried to make his ideas known. 他设法让别人知道他的想法。
She had to shout to make herself heard. 她必须大声喊才能让人听见她说话。
注意，其后通常不接现在分词作宾语补足语。如:
他让司机在外面等他。
误:He made the driver waiting for him outside.
正:He had the driver waiting for him outside.
(2) 接形容词作宾语补足语。如:
Have I made myself clear? 我的意思说清楚了吗?
We’ll do our best to make you happy. 我们会尽一切努力使你幸福。
(3) 接介词短语作宾语补足语。如:
Sit down and make yourself at home. 请坐，不要拘束。
3. make(使)通常不接现在分词的复合结构作宾语。要表示使某人 或某事一直做某事或处于做某事的状态中，英语可用 have sb doing sth。如:
他讲的滑稽的笑话使大家都笑了。
误:His funny joke made everyone laughing.
正:His funny joke made everyone laugh.
let用法三注意:
注意一:用作使役动词，表示“让”，其后接不定式的复合结构时，不定式不带 to。如:
Let me have a try. 我来试一试。
Let me pay for myself. 让我自己来付我的那份钱。
If you want help, let me know, will you? 如果你需要帮助，告诉我，好吗?
注意二:用作宾语补足语的动词与副词连用时，若意思明确，往往省略动词而只保留副词。如:
Let him (come) in. 让他进来。
Let her (pass) by. 让她过去。
注意三:let 很少用于被动语态。在被动语态中可改用 allow或其他表达。如:
After questioning he was allowed to go home. 经过问讯后，他得到允许，可以回家。
“have+宾语+动词”结构归纳:
