43　形容詞的原級　Track37

（1）表示原級比較的句型：A+as+形容詞或副詞的原級+as+B。

a. Eyes are as eloquent as lips.

b. You are as lazy as she.

我們也可以說：

c. The work is not as difficult as you think.　這個工作沒你想的那么難。

d. An adult human must take eight steps to go as far as a giraffe does in one stride.　長頸鹿邁一步相當于成人要邁八步。

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

世界上最深的山洞幾乎是帝國大廈高度的三倍。

（2）在否定句中，我們還可以將第一個as用so來替換：A+not so （或as）+形容詞或副詞的原級+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.　（注意否定詞在句首，故此句為否定句）沒有哪個國家像美國一樣投入這么少的財富到公共健康事業(yè)上。

（3）當我們要表示A是B的幾倍或幾分之幾時，我們用句型：A+幾倍（three times）或幾分之幾（a third）as+形容詞或副詞的原級+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）我們還可用the same...as句型來表示原級比較。這時句子結(jié)構(gòu)為：A+the same+名詞+as+B。注意在這個句型中，the same后面只能接名詞，而非形容詞。

I am as old as you.

不能說：I am the same old as you.*

而要用與形容詞old相對應的名詞age。所以這句話應改為：

I am the same age as you.
