高中英语语法as … as… 结构

　　高中英语语法as as 结构

　　 as as 结构在英语中用法较多，学生在平时的学习中会频繁地接触到此种结构。有部分学生认为 as as 结构中只能出现形容词或副词并且认为此结构只能用于原级比较，这种认识是单一的。实际上 as as 结构经过不同变化可以构成不同的短语和句式，这些短语和句式被灵活地运用于课文和练习中。如果学生对此结构的用法了解不多，就会在平时的学习中遇到障碍。为了帮助学生清除障碍，笔者就 as as 结构的几种用法介绍如下：

　　as + 形容词或副词原级 + as 意为和一样，表示同级的比较，但要注意第一个 as 为副词，第二个 as 为连词。根据比较对象和性质的不同又可以把此种结构分为三种：

　　（一） as as 结构用于表示不同人或物同一性质的比较，意为和一样 。例如：

　　The tree is as tall as the building(is) ．

　　这棵树和那栋楼一样高。

　　注意此结构也常用于形象比喻中： as cool as cucumber 沉着的， as stubborn as a mule 非常顽强的，倔强的， as clear as crystal 非常透明的， as poor as a church mouse 非常贫困的， as busy as a bee 像蜜蜂一样忙碌， as easy as ABC 像 ABC 一样容易， as deep as a well 像井一样深， as light as a feather 像羽毛一样轻， as soft as butter 像黄油一样软。这些短语生动活泼，浅显易懂，记住这些短语可以提高学生的英语写作和口语能力。

　　（二） as as 结构用于表示同一个人或物不同性质的比较，意为既又 。例如：

　　This swimming pool is as wide as it is long.

　　这个游泳池宽度和长度相等。

　　（三） as as 结构用于表示两个人或物不同性质的比较，表示程度相同或相当，意为而。在否定句中结构是 so/asas 。例如：

　　He was as handsome as his wife was beautiful ．

　　他长得非常英俊，他的妻子也长得非常漂亮。

　　He was as experienced as his brother was green ．

　　他经验丰富，而他兄弟却涉世未深。

　　He cannot run so/as fast as you.

　　他没你跑得快。

　　Danny is not so/as wise as he is witty ．

　　丹尼为人风趣，但欠明智。

　　需要注意的是： as + 形容词或副词原级 + as 结构的变体形式是 as + 形容词 + a + 单数名词 + as 或 as + many/much + 名词 + as 。意为和一样 。例如：

　　I dont want as expensive a car as this. ＝ I dont want a car as expensive as this ．

　　我不要这么贵的汽车。

　　This is as good an example as the other is.

　　这个例子和另外一个例子一样好。

　　Tony is as clever a boy as his brother ．

　　托尼是一个和他兄弟一样聪明的男孩。

　　I can carry as much paper as you can.

　　我能搬得动和你一样多的纸。

　　此外，变体结构的否定形式为 so +adj. + a/an + n. ( 单数 ) + as 。例如：

　　I am not so strong a man as I was.

　　我已经没有从前那么强壮了。 　　高中英语语法as as 结构
