考点3 9.4.3 comparative construction

Positive degree: as…as

Comparative degree: more…than Superlative degree: the most…

a. As…as Negative form: not as…as… not so…as… 1. *as 后面可以是 主语+（助词），非正式情况下，可以直接接主语。 My brother is as tall as I (am).

We don’t have as much time as John (dose). 2. adj和Nouns有两种位置关系，前置和后置。 Jim is as qualified a teacher as Bob. Jim is a teacher as qualified as Bob. I can’t move as heavy a box as this one. I can’t move a box as heavy as this one. *前置时，形容词在不定冠词+单数可数名词前。 *determiner限定词不可以后置，一般都在名词前面。

I can give you as many copies of this book as you want.(Many为determiner) ×I can give you copies of this book as many as you want. (×)

3. As..as..结构三种用法：(1) 两个人或者事之间具有同样的品质，(2)同一个人或者事两种不同品质的

比较，(3)两个人或事之前两种不同的品质。 (1) Susan is as intelligent as her husband. (2) Susan is as intelligent as she is beautiful.

(3) Susan is as beautiful as her husband is intelligent.

b. More…than…

1. 可加pre-modification: far, even, many, much, still, a lot, a great deal, rather, slightly… 2. adj和Nouns有两种位置关系，前置和后置。

Our neighbor has a larger house than ours. Our neighbor has a house larger than ours. Keener boys than he is will be chosen. Boys keener than he is will be chosen.

3. 当两个被比较的物体不属于同一等级的时候，前置修饰不起作用，

Mr. White is a professor much more learned than his students. ×Mr. White is a much more learned professor than his students. There are a lot of women more intelligent than John. ×There are a lot of more intelligent women than John. *determiner限定词不可以后置，一般都在名词前面。 He likes to order more food than he can eat. ×He likes to order food more than he can eat.

c. The most

一般要用of + 数字，in+地点，或者从句来limit the scope of comparison。 可是当最高级作为intensifier时候是可以不用limit the scope的～ I’d like to express my deepest gratitude…
