1).“as+ adj./adv. +as或not so(as)+ adj./ adv. +as.”句型。该句型常用来描述两个比较对象的程度上的相似或不同(即平时说的“等级比较和不等级比较”)。

My computer is not so(as) expensive as yours.

我的电脑不如你的贵重。

2).“as many/few+可数名词复数+as”或“as much/little(少的)+不可数名词+as”。前者描述数目上的接近，后者描述量的相近。

You may borrow as many books as you can.你能借多少书就借多少。“Drink as much water as you can.”the doctor said to him.

医生对他说到：“你要尽可能的多喝些水。”

3).“主语+比较级+than any other…”结构表示：主语所描述的事物比其他任何一个都……比较级形式表示最高级含义。

Li Ming is much cleverer than any other student in their class.

李明是他们班中最聪明的学生。

注意：若比较范围不同，than后应用“any+可数名词的复数形式+其他”。

China is larger than any countries in Africa.

中国比非洲上的任何国家都大。

4).诸如not, never之类的否定词与形容词或副词的比较级连用，表示最高级含义。意为：再没有比…更…的了。

It is not a better idea.这是再好不过的一个办法了。 I can’t agree more.

5).“形容词+to”结构也可表示比较含义。

This kind of car is superior in quality to that.

这种汽车的质量比那一种好得多(superior to意为：优于;胜过。)

Li ping is three years senior to Liu Gang.

李平比刘刚大三岁。(senior to意为：年长于;资格老于;地位高于。)

6).“no+比较级+than”结构表示对两个比较对象都进行否定(可由neither…nor…结构来改写)。例如： I’m no more foolish than you.我们俩都不傻。(相当于Neither I nor you is foolish.)

7).“not more+比较级+than”结构表示在程度上前者不如后者。

This book is not more interesting than that one.

这本书不如那本书有趣。

(相当于The book is less interesting than that one.)

8).“more+形容词+than+形容词”，意为：与其…倒不如…。

Jack is more hard than clever.与其说杰克聪明，倒不如说他学习用功。

9).would rather…than, prefer…to…, prefer to do…rather than…这三个句型表示“宁愿…而不愿…;喜欢…胜过…;宁愿做…而不愿做…”含义。虽无比较级形式，但表示比较级含义。

She would rather die than give in.她宁死不屈。

He preferred to go out rather than stay home.

他宁愿出去也不愿呆在家里。

10).“The+比较级…，the+比较级…”。该结构意为“越…，越…”。

The more difficult the questions are, the less likely he is able to answer them.

问题越难，他回答出来的可能性就越小。

注意：

1)要避免重复使用比较级。

(错) He is more cleverer than his brother.

(对) He is more clever than his brother.

(对) He is clever than his brother.

2)要避免将主语含在比较对象中。

(错) China is larger than any country in Asia.

(对) China is larger than any other countries in Asia.

3)要注意对应句型，遵循前后一致的原则。

The population of Shanghai is larger than that of Beijing.

It is easier to make a plan than to carry it out.

4)要注意定冠词在比较级中的使用。

比较：Which is larger, Canada or Australia?

Which is the larger country, Canada or Australia?
