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

該結構的意思是“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。

表示涉及數量或程度，可用“as much+不可數名詞+as”和“as many+可數名詞復數+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。
