第五句型：主语 + 及物动词 + 宾语 + 宾语补足语
先回顾一下本讲第一节中有关宾语和宾语补足语的概念。
这个句型也是考试的重点，主要有三个难点：
1) 要不要 "to"的问题：
The director wants you to come right now. (主任要你马上就来。)
句中to come 是宾语you的补足语。也就是说，当宾语补足语是动词时，一般要用 "to"连接。但是，以下情况例外：
n make, let, have等使役动词，如：
Shall I have him come here?(要我叫他来吗?)
I won't have him cheat me. (否定式，表示"容许"：我决不容许他欺骗我)
上述句型变为被动语态时，一般要加 "to"，如：
The nurse made the patient eat something. (护士让病人吃了点东西。)
→The patient was made to eat something.
有时，宾语补足语也可用 -ing形式，如：
His joke made us laughing for a couple of minutes. (他的笑话使我们笑了几分钟。- 注意后面的时间状语for a couple of minutes)
记住下面重要表达方式：
to have / get (something) done， 如：
I am going to have (get) my watch repaired.(我去修一下表。)
n see, hear, notice, observe, watch, look at, listen to 等感觉动词：
使用原则与上述大致相同。
2) 要不要 "it"的问题:
先看两个句子：
We sometimes find it difficult to get rid of a bad habit. (有时我们发现要改掉一个坏习惯很难。)该句的原始结构可理解为：We sometimes find (to get rid of a bad habit) difficult. 括号部分(动词不定式)为宾语，difficult为宾语补足语
The doctor has made it clear to you that there is nothing wrong with your stomach.(医生已经跟你说得很清楚了，你的胃没有什么问题。)该句的原始结构可理解为：The doctor has made (there is nothing wrong with your stomach)clear. 括号部分(句子)为宾语，clear为宾语补足语
