牢记make possible的三种形式：
1. make+名词+possible;
His financial aid makes this trip possible.
2. make+possible+名词(名词短语较长时)
His financial aid makes possible the poor Chinese student’s entering of the world famous university.
3. make it possible (for sb.)to do (见形式宾语部分)
The father’s hard labor makes it possible for the son to receive better education.
定语从句可分为限定性和非限定性两种，其主要区别为：
1. 非限定性定语从句中，引导词和先行词之间需用逗号隔开。
2. 非限定性定语从句中，引导词一般不用that，
在修饰人时用who, whom, whose
He had three children, all of whom had graduated from college.
在修饰物时用 which
部分状语从句可以省略，在填空题中时有出现
如：Although defeated, he did not lose heart. (从句中省略了he was)
If inFORMed timely, I wouldn’t have missed the meeting. (从句中省略了I were)
注意: 当现在完成时的时间状语是for + 一段时间(已经有…时间了), 和since + 一个时间点(自从…以来)的时候, 句中的谓语不能是非延续性动词(暂短性动词),
如不能说 :I have borrowed the book for ten days. (错误: borrow这个动作是发生在图书出纳台上的一次性动作, 不能延续, 因此不能和for引导的时间状语连用)应改为: I have kept the book for ten days.
这样的暂短性动词还有: buy/sell, break, die, graduate, drop等倒装
倒装句就是将正常的陈述语序加以变化，主要作用是强调被提前的部分
倒装句可分为全部倒装和部分倒装两种：
一、全部倒装
谓语动词提前至主语之前为全部倒装，如： Out came his guest.On the hill stood a little cottage that contained heaps of hay.There lived an elderly lady whose husband died long ago.
