He has as many books on information technology as I have. 他拥有的信息技术书和我拥有的同样多。(这是比较状语从句还是定语从句)
I gave him as much as he could eat. 他能吃多少,我就给了他多少。
He has earned as much money as I have. 他赚的钱和我赚的一样多。
这类 as…as…句式到底是比较状语从句还是定语从句,区分的原则是:
如果是比较状语从句,那么一般能找出两个具体的供比较的人或事物,且通常可以进行相关省略(即使对 as 从句进行最大限度的省略,只剩下比较物,句子意思仍然清楚)。如:
He has as many books on information technology as I (have).——he 与 I 作比较,其中 as 从句中的 have 可以省略。
He has earned as much money as I (have). —— he 与 I 作比较,其中 as 从句中的 have 可以省略。
但如果是定语从句,则一般找不出具体的供比较的人或事物,且除非很特殊的情况,一般不允许有所省略。如:
I gave him as much as he could eat.——本句不是将 I 与 he 作比较,其中 as 从句中的 could eat 不可省略。
又如下面一句也是定从句:
He smokes as expensive a cigarette as he can afford. 他抽一种他买得起的最贵的烟。
He has as many books on information technology as I have. 他拥有的信息技术书和我拥有的同样多。(这是比较状语从句还是定语从句)
I gave him as much as he could eat. 他能吃多少,我就给了他多少。
He has earned as much money as I have.他赚的钱和我赚的一样多。
回答如下:
以上都是为比较状语从句
结构1为: 主语+谓语+as many +可数名词复数+as+主语+谓语
结构2为: 主语+谓语+as much as +主语+谓语
结构3为:主语+谓语+as much +不可数名词单数+主语+谓语
备注:
(1)前面主语+谓语为主句的主语和谓语
(2)后面的主语+谓语为从句的主语和谓语
(3)第1个AS 为副词,第2个AS 位连词引导比较状语从句
例如
Their school is as beautiful as ours
Their school is twice as big as ours
