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的用法，大家一起来看看吧! 初中英语使役动词的用法: 最常见的使役动词有:let / make / have / get. 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.
[图片0] 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? 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?

(2) 在否定句或疑问句中，可以不用助动词do(在非正式文体中可在have之后加got)(主要见于英国英语中)，也可用助动词do(主要见于美国英语中)。如: He hasn’t (got) a computer.=He doesn’t have a computer. 他没有电脑。 在非正式的美国英语中，有时也用 have got 的形式，且有时还可将 have 省去。如: I (‘ve) got a problem. 我有个问题。 (3) 即使在英国英语中，若指经常性的现象，也通常用助动词 do 来构成疑问式和否定式。且不与got搭配;若指暂时现象，则不用助动词do来构成疑问式和否定式，且可以与got连用(注:在美国英语中则无此区别，一般都用do构成疑问式和否定式)。如: Have you (got) a cold now? 你感冒了吗? Do you often have colds? 你感冒了吗? I haven’t got to work tomorrow. 我明天不必上班。 I don’t usually have to work on Sundays. 星期天我通常不必上班。 (4) 表示“拥有”时，构成否定式有两种可能:若其后的名词没有限定词修饰，则通常用 have no;若有限定词(如a, any, much, many, enough等)修饰。则通常用 have not。如: I have no friends. / I haven’t any friends. 我没有朋友。 He hasn’t much money. 他没有很多钱。 2. 表示动作，如表示“吃(=eat)”“喝(=drink)”“拿(=take)”“收到(=receive)”“度过(=spend)”等时，在用法应注意以下几点: (1) 可用于进行时态，但一般不用于被动语态。如: 误:Lunch is had by him. 正:He is having lunch. 他在吃中饭。 (2) 不与 got 连用。如: 误:I’d like to have got a look at it. 正:I’d like to have a look at it. 我想看看它。 (3) 一般不用缩略式。如: 误:We’d a good time at the party. 正:We had a good time at the party. 我们在晚会上玩得很高兴。 (4) 构成否定式和疑问式时，必须用助动词 do。如: 误:When had you breakfast? 正:When did you have breakfast? 你什么时候吃早餐? 动词get的用法与搭配: 用法一:用于“get+名词+宾补”，该宾语补足语可以是: 1. 不定式 其意为“使……做……”(具有使役性)。如: He got his son to post the letter. 他叫他儿子去寄信。 You must get them to come over here. 你必须想法让他们到这儿来。 He couldn’t get the car to start and went by bus. 他因无法发动车子，所以就乘公共汽车去。 2. 现在分词 其意为“使……(开始)起来”或处于某种状态。如: What he said got us thinking. 他说话使我们思考起来。 Can you get the clock going again? 你能让这钟重新走起来吗? It’s not hard to get him talking; the problem is stopping him. 要他说话不难，难的是说开了止不住他。 3. 过去分词 其中的过去分词表示被动关系。如: Go and get your hair cut. 去把头发理了。 I’ll try to get it published. 我要设法让它发表(出版)。 He got his fingers caught in the door. 他的手指让门给夹给了。 You must get the work done by Friday. 你必须最迟在星期五以前把工作做完。 注:有时表示遭遇。如: He got his watch stolen. 他的表被偷了。 He got his fingers caught in the door. 他的手指让门给夹住了。 4. 形容词 意为“使……(变成某种状态)”。如: I can’t get the door open. 这门我打不开。 We’ve got everything ready. 我们已把一切都准备好了。 用法二:用作连系动词，表示状态的变化，其后所接表语可以是: 1. 形容词 The weather is getting warm. 天气暖和起来了。 She got quite impatient. 她变得很不耐烦起来。 注意，用作连系动词的get 之后一般不接表示颜色的形容词，如不说 get black / white / red，遇此情况可用 go 或 turn。 2. 过去分词 He got lost in the woods. 他在树林里迷路了。 They got discouraged and went home. 他们感到泄气回家了。 “get+过去分词”结构有时是系表结构，有时是被动语态，这主要看其中的过去分词是强调状态(为系表结构)还是强调动作(为被动语态)。表示被动时，与用 be 有区别:一般说来，用 get 除表示更强的动作意味外，还往往表示一种突发性的，出乎意料的偶发事件。如: How did the window get broken? 这窗子是怎么打破的? He got killed when crossing the road. 过马路时他被车撞死了。 3. 不定式 Soon they got to be good friends. 不久他们就成了好朋友。 You’ll like her once you get to know her. 你一旦了解她，就喜欢她了。 能用于get后的不定式不多，常见的有to know, to like, to be等。 4. 现在分词 Things haven’t really got going yet. 活动还没开展起来。 Then we got chatting together. 后来我们在一起聊了起来。
