重點語法之a(chǎn)s ... as的用法

例題解析

1. 單選題：My bike is? ? ? ? ? Lucy’s.

A. as better as

B. as good as

C. as well as

D. as best as

【解析】本題考查同級比較的用法。as+形容詞原級+as，和……一樣。故答案選B。

句意：我的自行車和露西的一樣好。

2. 翻譯句子：

今天北京的天氣不如太原的好。(as good as)

【解析】本題考查同級比較的否定用法。“不如……好”可表示為：not as/so ... as ...，本題用not as good as；地點前注意需要加介詞in，另外，第二個as后的比較對象“太原的天氣”可用that in

Taiyuan指代。故本題可譯為：

Today the weather in Beijing isn’t as good as that in Taiyuan.

as ... as的用法

該結(jié)構(gòu)的意思是“與......一樣”。

接形容詞或副詞的原級，在否定句中，第一個 as 也可換成 so。如：He doesn't study as [so] hard as his brother. 他學習不如他弟弟努力。

表示涉及數(shù)量或程度，可用“as much+不可數(shù)名詞+as”和“as many+可數(shù)名詞復數(shù)+as”。如：He doesn’t pay as much tax as we do / as us. 他沒我們交的稅款多。

可用(not) nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等修飾，并且這些修飾語必須置于第一個as之前，而不能置于其后。如：This room is twice as large as that one. 這個房間是那個房間的兩個大。

as…as…不表示比較的幾個常見句型。

一、as…as possible／sb can盡可能的……

Please answer my question as soon as possible．

請盡快回答我的問題。

The detective is searching the man as carefully as he can．

那個偵探正在盡可能仔細地搜查那個男子的身體。

二、as…as usual／before像以前一樣……

She looks as pretty as before．

她看起來和以前一樣漂亮

Though they failed，they still worked as hard as usual．

盡管他們失敗了，但他們?nèi)韵褚郧耙粯优ぷ鳌?/p>
