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.
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?
I wont have him cheat me.
上述句型变为被动语态时，一般要加 to，如：
The nurse made the patient eat something.
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.
记住下面重要表达方式：
to have / get done， 如：
I am going to have my watch repaired.
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. 该句的原始结构可理解为：We sometimes find difficult. 括号部分为宾语，difficult为宾语补足语
The doctor has made it clear to you that there is nothing wrong with your stomach.该句的原始结构可理解为：The doctor has made clear. 括号部分为宾语，clear为宾语补足语
