angry.
3. 当先行词受such, the same修饰时，常用as
I have never heard such a story as he tells.
He is not such a fool as he looks.
This is the same book as I lost last week.
注意：当先行次由the same修饰时，偶尔也用that引导定语从句，但是和由as所引导的定语从句意思不同
She wore the same dress that she wore at Mary’s wedding. 她穿着她在MARY婚礼上穿过的一条裙子。
She wore the same dress as her young sister wore. 她穿着和她妹妹所穿的一样的裙子。
（三）以the way为先行词的定语从句通常由in which, that引导，而且通常可以省略。
The way in which/ that he answered the question was surprising.
(四) but有时也可以做关系词引导定语从句
There are very few but understand his idea. ( but= who don’t )
(五) 区分定语从句和同位语从句
1．定语从句修饰先行词，它和先行词是修饰关系；同位语从句说明先行词的具体内容，是补充说明的关系
The plane that has just taken off is for London. 定语从句
The fact that he has been dead is clear. 同位于从句
2．定语从句由关系代词或者关系副词引导，关系词在句中充当成分，有时可以省略；同位语从句主要由that引导，在句中一般不做成分；句子也可以由when, where, how, why, whether, what等词引导。
The news he told me is true.
The news that he has just died is true.
The problem that we are facing now is how we can collect so much money.
The problem how we can collect so much money is difficult to solve.
3. 同位语从句和先行词一般可以用be动词发展成一个完整的句子，而定语从句不可以
The idea that we could ask the teacher for advice is wonderful.
The idea was that we could ask the teacher for advice.
The fact that the earth moves around the earth is known to all.
The fact is that the earth moves around the earth.
