理工类辅导资料：比较级的主要句型
(1) 原级比较：as 形容词或副词原级 as， 否定式：not so (或as) 形容词或副词原级 as
注意问题：as…as 之间的形容词或副词是否采用了原级；as…as 之间该用形容词还是副词；用as much as 还是用as many as
表示倍数时用下面结构， 如3倍：three times as …as…
例如：
The size of the island is about ______ that of this one.
A.three times as much as B.as three times much as
C.as three times greater than D.three times as big as
解题思路：B、C违反了上述句型规定，A、D的区别是size(大小 / 尺寸)是与much搭配还是与big搭配，D是对的。
