玛丽学习极为努力。

其他例如：

as wise as wise can be  再聪明不过了

as white as white can be 白得不能再白了

as wrong as wrong can be 错得太离谱了

（五）“as…as usual/ever/before”此结构的意思是“像平时/以前一样”。如：

He gets up as early as usual.

他像平时一样早起。

He seems to be as busy as ever.

他似乎像往常一样忙碌。

He works as hard as ever.

他和往常一样努力工作。

She was as beautiful as ever after so many years.

过了这么多年她美丽如故。

（六）“as…as…结构”可以用来表示倍数。具体用法是倍数词：twice，three times，half或a quarter置于第一个as之前，意思是“……是……的几倍”。如：

You are not half as clever as you think you are．

你可不像自己想象的那么聪明。 

She isn’t going out with a man who is twice as old as she． 

她不打算和一个比她大一倍的人出去散步。

我们今年的棉花产量是去年的两倍。

She works three times as hard as I.

她用功的程度是我的三倍。

需要注意的是，在比较级前还可以用“over, more than” 等表示“比……倍数还要多”。如：

He is more than three times as rich as I.

他的财富是我的三倍还不止。

I am more than twice as old as he.

我的年龄是他是两倍还不止。

He studies more than three times as hard as I.

他用功的程度是我的三倍还不止。

He has collected more than four times as many stamps as I.

他搜集的邮票是我的四倍还不止。

（七）词组“as well as”意思是“像…一样好，既…又…,除之外还”，此短语使用频率十分高，用途非常广泛。它可以用作连词和介词，也可以表示比较。具体用法如下：

1. 词组“as well as”用作连词。连接两个并列的同等成分，其意义为“不但……而且……”，“既……又……”，这时相当于“not only…but also…”。它所连接的部分既可以是单词、短语，也可以是句子。例如：

He speaks Japanese as well as English and French.

他不但讲英语和法语，而且还讲日语。

2. 词组“as well as”用作介词。此时，相当于besides，意为“除……之外”，后常接名词、动名词。如：
