43　形容词的原级　Track37

（1）表示原级比较的句型：A+as+形容词或副词的原级+as+B。

a. Eyes are as eloquent as lips.

b. You are as lazy as she.

我们也可以说：

c. The work is not as difficult as you think.　这个工作没你想的那么难。

d. An adult human must take eight steps to go as far as a giraffe does in one stride.　长颈鹿迈一步相当于成人要迈八步。

e. The world's deepest cave in the mountain is almost three times as deep as the Empire State Building is high.

世界上最深的山洞几乎是帝国大厦高度的三倍。

（2）在否定句中，我们还可以将第一个as用so来替换：A+not so （或as）+形容词或副词的原级+as+B。

a. He is not so/as clever as you.

b. No other modern nation devotes so small a portion of its wealth to public health as the United States does.　（注意否定词在句首，故此句为否定句）没有哪个国家像美国一样投入这么少的财富到公共健康事业上。

（3）当我们要表示A是B的几倍或几分之几时，我们用句型：A+几倍（three times）或几分之几（a third）as+形容词或副词的原级+as+B。

a. This book is twice as thick as that one.

b. The earth has a mass nearly one hundred times as much as that of the moon.

（4）我们还可用the same...as句型来表示原级比较。这时句子结构为：A+the same+名词+as+B。注意在这个句型中，the same后面只能接名词，而非形容词。

I am as old as you.

不能说：I am the same old as you.*

而要用与形容词old相对应的名词age。所以这句话应改为：

I am the same age as you.
