之前小編與大家一起學(xué)習(xí)了形容詞比較等級(jí)的構(gòu)成方式，而形容詞比較等級(jí)用于句子當(dāng)中便形成了所謂的“比較結(jié)構(gòu)”。英語比較結(jié)構(gòu)最主要的有三種：as...as結(jié)構(gòu)，more...than結(jié)構(gòu)以及the most...結(jié)構(gòu)。as...as結(jié)構(gòu)意為“和...一樣”，其用法主要如下：

一、基本模式：as+形容詞原級(jí)+as-分句

??1.主句主語與as-分句主語不同，比較項(xiàng)目相同，此時(shí)as-分句有所省略。如：

??? Jack is as clever as Tom.

??2.主句主語與as-分句主語相同，但比較項(xiàng)目不同，此時(shí)as-分句不可用省略句。如：

????The girl is as brilliant as she is beautiful. （這個(gè)女孩既漂亮又聰明。）

??3.主句主語與as-分句主語不同，比較項(xiàng)目也不同，此時(shí)as-分句不可用省略句。如：

????Her uncle?was as base and unworthy as?her father had been upright and honorable.

??（她叔叔卑鄙齷齪，不像她父親那樣正直可敬。）

??4.基本模式的否定形式：

????Jack is not as clever as Tom. 或 Jack is less clever than Tom.

二、變體模式：

??1. as many/much+名詞+as-分句：

??? She has eaten as many apples as her sister.

??? He took as much water as he needed.

??2. as+形容詞原級(jí)+名詞詞組+as-分句：

??? Lucy is as clever a girl as her sister.

??3. 變體模式的否定形式：

??? He didn’t take as much water as he needed.

需要注意的是，同一句話，采取基本模式和變體模式，它們的含義基本相同，但句子的側(cè)重點(diǎn)有所不同。例如：

基本模式：I haven’t seen a car as old as this for years.（重點(diǎn)在名詞car）

變體模式：I haven’t seen as old a car as this for years.（重點(diǎn)在形容詞old）

三、as...as結(jié)構(gòu)常用于形象比喻中：

??? as rich as a jew 極其富有 ???????????????????????????? as cool as cucumber 沉著冷靜 ?????????????

??? as light as a feather 輕如鴻毛??????????????????????? as soft as butter 性格軟弱

??? as poor as a church mouse 一貧如洗???????????? ?as clear as crystal 清澈透明，一清二楚

??? as busy as a bee 忙忙碌碌 ??????????????????????? ?? as easy as ABC 相當(dāng)容易 ?

??? as deep as a well 高深莫測(cè) ????????????????????????? ?as stubborn as a mule 非常頑固，倔脾氣
