首先定语从句的连接词不可以用what.
一.定语从句及相关术语
1.定语从句:修饰一个名词或代词的从句称为定语从句,一般紧跟在它所修饰的先行词后面。
2.关系词:引导定语从句的关联词成为关系词
关系词有关系代词和关系副词。关系代词有that, which, who, whom, whose, as 等;
关系副词有where, when, why等。
关系词常有3个作用:1,引导定语从句。2,代替先行词。3,在定语从句中担当一个成分。
用which的情况
a) 在引导非限定性定语从句时。
The tree, which is four hundred years old, is very famous here.
b) 介词后不能用。
We depend on the land from which we get our food.
We depend on the land that/which we get our food from.
2) 只能用that作为定语从句的关系代词的情况
a) 在there be 句型中,只用that,不用which。
b) 在不定代词,如:anything, nothing, the one, all, much, few, any, little等作先行词时,只用that,不用which。
c) 先行词有the only, the very修饰时,只用that。
d) 先行词为序数词、数词、形容词最高级时,只用that。.
e) 先行词既有人,又有物时。
举例:
All that is needed is a supply of oil.
所需的只是供油问题。
