用法：表示双方在程度、性质、特征等某方面相等时，用“a s + 原级形容词/副词+ as”的结构；表示双方不相等时，用“not so(as) + 原级形容词/副词+ as”的结构；表示一方是另一方的若干倍时，用“倍数+ as + 原级形容词/副词+ as”的结构。

如：Xiao Wang is as tall as Xiao Yu. 小王和小于一样高。

This building looks not so (as) high as that one.这座大楼看起来了不如那座高。

Miss Xu speaks English as fluently as you.许老师将英语和你一样流利。

This room is three times as large as that one. 这间房是那间的三倍大。

2.比较级的构成和用法掌握比较级的变化规则，熟记少数不符合规则的特殊形容词和副词。

比较级的用法：(1)对方比较，表示一方超过另一方时，用“比较级+than”的结构表示。

This picture is more beautiful than that one.这幅画比那幅漂亮得多。

(2)表示一方不及另一方时，用“less +原级+than”的结构表示。

This room is less beautiful than that one.这房间不如那房间漂亮。

(3)表示一方超过另一方的程度或数量时，可在比较级前加表示程度的状语，如even, a lot, a bit, a little, still, much, far, yet, by far等修饰。

He works even harder than before. 他比以前学习更刻苦了。

注意：英语的比较级前如无even, still或yet等时，译成汉语时可用“较”或“……一些”或不译出，一般不译成“更”。

She is better than she was yesterday. 她比昨天好多了。

Please come earlier tomorrow. 明天请早点来。

注意：by far通常用于强调最高级。

用于比较级时，一般放在比较级的后面，如在前面，应在二者中间加“the”。

He is taller by far than his brother. 他比他兄弟高得多。

He is by far the taller of the two brothers. 他在两兄弟中绝对是高的。

课堂探究教师点拨(4)表示一方随另一方的程度而变化时，用“the +比较级（主语+谓语），the +比较级（主语+谓语）”的结构（意为“越……越……”）。

The harder he works, the happier he feels.他工作越是努力，他就越感到幸福。

(5)不与其他事物相比，表示本身程度的改变时，用“比较级+and+比较级”的结构。

The weather is getting colder and colder. 天气越来越冷了。

The girl becomes more and more beautiful. 这姑娘越来越漂亮了。

(6)某些以-ior结尾的形容词进行比较时，用to代替than。

这些词有inferior（劣等的，次的）, superior（较好的，优于……）,junior（资历较浅的）, senior（资格较老的）, prior（在……之前）等。

He is superior to Mr. Zhang in chemistry.他在化学方面高于张老师。

(7)在比较从句中为了避免重复，我们通常用that(those)、one(ones)代替前面出现的名词。

that指物,one既可指人又可指物。

that可代替可数名词单数和不可数名词，而one只能代替可数名词。

The book on the table is more interesting than that(或the one)on thedesk.A box made of steel is stronger than one made of wood.(8)倍数表达法。

用times 表倍数通常用于三倍以上，两倍可以用twice或double。

①A is three(four, etc.)times the size(height, length etc.)of B.②A is three(four, etc.)times as big(high, long, etc.)as B.③A is three (four, etc.)times bigger(higher, longer, etc.)than B.The new building is four times the size(the height)of the old one.这座新楼比那座旧楼大/高三倍。

Asia is four times as large as Europe.亚洲比欧洲大三倍。

Your school is three times bigger than ours.你们的学校比我们的学校大三倍。
