例如:

None is blind as those who won't see. Anyone who is over sixteen is allowed in.

(4)当先行词与关系代词之间有较复杂的短语或从句隔开时. 例如:

I was the only person in my office who was invited.

A new master will come tomorrow who will teach you German. 4. 由what,as引导的定语从句 1)what引导的定语从句

what作为关系代词时,用法很特殊,被看作是先行词和关系代词的结合体.一般情况下被理解为the things that,all that或something that,在句中充当主语或宾语等名词性成分.它引导从句时,前面不应该再出现先行词. 例如:

For Williams, those activities became what he calls \ (1)what单独使用,后不接名词,表示物或人 例如:

She is not what she used to be.

One difficulty is that almost all of what is called behavioral science continues to trace behavior to states of mind, feelings, traits of character, human nature, and so on. (2002) (2)what后接名词——\所有的……,尽可能多的……\ 例如:

He claims to be an expert in astronomy, but in fact he is quite ignorant on the subject. What little he knows about it is out of date and inaccurate. (1997) 2)关系代词as引导的定语从句

as可引导限制性定语从句和非限制性定语从句,根本区别在于: 前者as只用在一些固定结构如such/the same/as修饰的先行词后面;而后者没有结构要求. 例如:

As can be seen from the comparison of these figures, the principle involves the active participation of the patient in the modification of his condition. (1999) 定语从句
