使役动词have let make 的用法1.have的用法1). have 宾语省to不定式：表示主语“要”“使”“让”宾语干某事,宾语和宾补之间是一种主动关系.而且还可以与情态动词will, would连用,不用于被动结构.The rich lady had the singer eat with his servants.I will have him come and help you.2). have 宾语现在分词：表示让某人或物连续进行某动作或处于某状态中,宾语和宾补是一种主动关系.亦可转化为“劝说,鼓励”宾语干某事.The two cheats had the lights burning all night long.He had us waiting for him three hours yesterday.I have them all talking to each other in English. 我鼓励他们用英语交谈.3). have 宾语过去分词：表示主语的主观意志,即主语让别人为自己完成某事,宾语和宾补是动宾关系.还可以表示主语遭受到来利或不测的事.Tom said he had had his TV set repaired.Tom had his wallet stolen on the bus yesterday.“别人”在句中一般不出现,这是它与结构1)的区别所在.试比较：Have you washed your clothes? 你洗了衣服了吗?(自己洗)Have you had your clothes washed? 你叫人洗了衣服了吗?(别人洗)4). have 宾语形容词/副词/介词短语作宾补Please have your tickets ready.The Emperor had nothing on.I am sure I’ll have him in the argument.2.let的用法1). let 宾语省to不定式：表示主语“要”“使”“让”宾语干某事,宾语和宾补之间是一种主动关系,罕用于被动语态.有时也可指一种假设.let后不能接现在分词,过去分词作宾补.Let them stay in the classroom and do their exercises themselves.Let AB be equal to CD. 假设AB等于CD.2). let 宾语副词/介词短语作宾补Let me in and let them out.Who let you into the building?3.make的用法1). make 宾语省to不定式：表示主语“要”“使”“让”宾语干某事,宾语和宾补之间是一种主动关系.此结构常用被动结构.make后不接现在分词作宾补.The teacher made the naughty boy stand there for an hour.The naughty boy was made to stand there for an hour.2).make 宾语过去分词,此结构中的宾语指人时常用到反身代词.He raised his voice to make himself heard.Can you easily make yourself understood in English?They will make an important plan known to the public soon.3). make 宾语形容词,宾语亦可是从句.The news made her happy.He made it clear that he objected to the proposal.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。
使役动词make用法注意：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。
使役动词后不定式符号to的省略问题：第一种情况：当不定式用于let, make, have等使役动词后作宾语补足语时，不定式必须省略to。
如：Let me give you a piece of advice. 让我给你一个忠告。
He had his son clean the car. 他叫他的儿子擦车。
They made me repeat the whole story. 他们非让我把整个事件再说一遍。
但是，当使役动词用于被动语态时，其后的不定式则必须要带to。
如：虽然他以前经常把他小妹妹弄哭，但今天他被他小妹妹弄哭了。
误：Though he had often made his little sister cry, today he was made cry by his little sister.正：Though he had often made his little sister cry, today he was made to cry by his little sister.注意，表示使役意义的let和have很少用于被动语态。
第二种情况：表示“使”“迫使”的force, get, oblige等动词后接不定式作宾语补足语时，不定式必须带to(不能省略)。
如：They forced her to sign the paper. 他们强迫她在文件上签字。
The police obliged him to leave. 警方强迫他离开。
Once she has decided on doing it, you won’t get her to change her mind. 一旦她下决心干，你就别想使她改变主意。
