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。最常见的使役动词有：let / make / have / get.
♦ Do you like Linda’s new hairstyle? She had her hair cut yesterday.
♦ Why don’t you get your hair cut in a new style?
♦ The teacher made us do four hours homework yesterday.
♦ A lot of parents let their teenage children drink alcohol at home.
♦ You shouldn’t let your dog annoy people on the beach.
♦ Do you think parents should let their teenage children smoke at home?
♦ My parents won’t let me go out.
♦ If you let me drive your car to the party, I’ll wash the dishes.
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 doctorcheckmy blood pressure every visit.
I always have my daughtercookdinner 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 childrento playmore sport.
How can we get childrento eatmore vegetables?
大家看到了吧，上面的例句中主语并没有做动词的动作。至于have后面什么时候用过去分词什么时候用动词原形，get后面什么时候用过去分词什么时候用不定式，你发现规律了吗？
