原级比较

Tom is as efficient a worker as Peter.Tom is a woker as efficient as Peter.

老师，这两句话的不同之处？

两个句子没什么差异，都译为：汤姆是一个像彼得一样能干的工人。句（2）中的as efficient as Peter是形容词短语作后置定语，等于who is as efficient as Peter构成的定语从句。

有的形容词 与介词搭配构成形容词短语作后置定语时, 大家可以使用分隔形式，即它和其后的介词拆开, 将形容词置于名词之前, 将介词短语置于名词之后。比如:

Thats a question different from this one. = Thats a different question from this one.那是一个与此不一样的问题。

▲as...as构成的形容词短语作后置定语时同样可以采取分隔形式。比如：

She is a girl as clever as Mary. = She is as clever a girl as Mary.她是一个象玛丽一样聪明的女孩。
