形容詞做定語和從句做定語

在英文中我們可以用形容詞或其他詞類或非謂語動詞修飾一名詞，如I dont like impatient guys. Over two million people suffered from the blackout in New York. Those under 17 are not allowed to see the movie. Do you the number of foreign guests coming to the surprise party? 但是要表達更為複雜的意思，簡單用形容詞無法搞定，我們要用一個句子才行，這種句子來修飾名詞，做定語。

一、定語從句中的基本概念。

1)定語從句：修飾名詞或代詞的`從句叫定語從句。

2)先行詞：位置在定語從句前，被定語從句修飾或限制的對象叫先行詞。現在我們來全面理解先行詞：

① 先行詞可以不只是一個詞。儘管我們他這個對象稱為先行詞，但它不一定就是一個詞，它可以是：

A.一個詞

The woman who lives next door is a famous singer.

He who hesitates is lost.

B.短語

He likes climbing mountains, which is a good exercise.

C.一個分句

He said that he had no time, which is not true.

D.一個完整句子

He arrived an hour later, which annoyed his girlfriend very much.

My girlfriend likes chatting online with other guys, which really drives me crazy.
