定语从句先行词做主语 篇2
先行词并不能决定that能不能省略,要看关系代词that本身在从句中的作的成分。
1.先行词为人:
1)人做主语——关系代词用who且不可省略
2)人做宾语——关系代词用whom/who/不填
2.先行词为物:
1)物做主语——关系代词用that/which
2)物做宾语——关系代词用that/which/不填
不填就是可以省略.
举个例子:A)The boys that are playing footballl are from America.
that修饰限定男孩们,且男孩们在句中做主语.
省略掉之后就变成:The boys are playing football are from America.很显然是不可以的
B)The news (that) she heard is true.
that修饰限定消息,消息又在主句中做主语,但是that在从句中作宾语成分,所以可以省去.
另外,指人可用that who,以下情况多用who;Those people做先行,There be的结构中;先行指人不定代,从中做主who要在;
例:People who create computer viruses are called hackers.
一般多用who,但并不代表就不能使用that,这仅是约定俗成的用法.
