定语从句在什么情况下只能用that

Question

如题所述

Answer 1

1、定语从句修饰的词（即，先行词），前面有形容词最高级时。

This is the best film that I have seen.

先行词是film，前面有the best修饰它，这时候只能用that，强调“最好的”。

2、先行词被the very/the only/the same/the last等修饰时。

She is the only girl who has got a prize.

先行词是girl，前面有the only修饰它，这时候只能用that，强调“唯一一个”。

3、先行词被序数词修饰时。

The first place that they visited was the Big Ben.

先行词是place，前面有the first修饰它，这时候只能用that，强调“第一个”。

定语从句关系构成

关系从句的句法功能主要是充当定语。在英语中，关系从句通常位于它所修饰的词（组）之后。被关系从句修饰的词（组）叫做先行词，引导关系从句的词称为关系词，关系词指代先行词并在关系从句中充当一定的成分。例如：

This is the book which interests me.

“which interests me”是关系从句，修饰先行词“book”，而关系词“which”指代先行词“book”并在关系子句中充当主语。

这句话可以拆分为两个句子来理解：“This is the book”和“The book interests me”。
