as……as的用法及例句

Answer 1

as...as意为＂和……一样＂，表示同级的比较。使用时要注意第一个as为副词，第二个as为连词。其基本结构为：as+ adj./ adv. +as。

1、接形容词或副词的原级，在否定句中，第一个as也可换成so。

例句：He doesn't study as (so) hard as his brother.他学习不如他弟弟努力。

2、表示涉及数量或程度，可用“as much+不可数名词＋as”和“as many+可数名词复数＋as”。

例句：He doesn’t pay as much tax as we do / as us.他没我们交的税款多。

3、可用（not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等修饰，并且这些修饰语必须置于第一个as之前，而不能置于其后。

Answer 2

as…as是同级比较的用法。在中间可以放入形容词，副词。
eg. He runs as fast as me/I. 他和我跑得一样快。这里的fast是副词。
She is as beautiful as me/I. 她和我一样漂亮。
还可以在中间加入倍数的比较，用法可以见例句。
eg. My father's hand is twice as big as mine. 我爸爸的手是我的两倍大。
注意：as…as的比较对象（如前面他和我，我爸爸的手和我的手）要一致。
前面一个例句他、她和我的比较，我可以用宾格，也可以用主格。

Answer 3

一.此句型用于平级比较，第一个as是副词，第二个as是连词，中间加的是形容词或副词的比较级。例如：
This bridge is as long as that one.
He runs as fast as Jack.
二.中间如果加名词的话分为两种情况。
1 加可数名词单数，注意要先加形容词再加不定冠词。如
He is as good a boy as Tom.
2 加可数名词复数，不可数名词只能用many和much修饰，如
I have as many books as you have.
I have as much money as you have.
