学英语 使役动词的用法

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 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 play more sport.

How can we get children to eat more 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？
