as…as的用法 as…as的用法有哪些

1、此句型用於平級比較，第一個as是副詞，第二個as是連詞，中間加的是形容詞或副詞的比較級。例如：

This bridge is as long as that one.

He runs as fast as Jack.

2、中間如果加名詞的話分為兩種情況。

（1）加可數名詞單數，注意要先加形容詞再加不定冠詞。如

He is as good a boy as Tom.

（2）加可數名詞複數，不可數名詞只能用many和much修飾，如

I have as many books as you have.

I have as much money as you have.
