高中英语比较级总复习

1、概述比较级comparative degree在英语中通常用下列方式表示的词：在形容词或副词前加more(如more natural,more clearly )或加后缀-er(newer,sooner ) 。典型的是指形容词或副词所表示的质、量或关系的增加。英语句子中，将比较两个主体的方法叫做“比较句型” 。其中，像“ A 比B更”的表达方式称为比较级。组成句子的方式是将形容词或副词变化成比较级的形态。比较级的构成规则1. 一般单音节词和少数以-er, -ow结尾的双音节词，比较级在后面加-er,最高级在后面加 -est；( 1)单音节词如：smallfsmaller fsmallestsh

22、能熟练掌握。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” ) 。例如：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。例如：You may borrow as many books as you can. 你能借多少书就借多

24、n 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-更一的了。例如:It is not a better idea.这是再好不过的一个办法了。I have never heard such an interesting story.5. “形容词 +to ”结构也可表示比较含义。例如：我从来没有听过比这更有趣的故事了。This kind of car is superior in quality to that.（superior to 意为：优于；胜过。 ）Li ping is thre

25、e years senior to Liu Gang.这种汽车的质量比那一种好得多李平比刘刚大三岁。 (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。例如：This book is not more interesting than tha

26、t one.这本书不如那本书有趣。 ( 相当于 Thebook is less interesting than that one.)8 .“形容词比较级+than+形容词”，意为：与其-倒不如一。例如：Jack is much harder 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。例如：She would rather die than give in.她宁死

27、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”。例如：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。11 .what 有时也可以表示 “比较” 关系，说明两种事物的相同或相似性。 what 的该种用法常用于书面语，用来加强修辞效果，含有比喻含义，相当于as,意为“好比-；正如一；就像一样"。wha

28、t的该类用法共有3种情况：(1)A is to B what C is to DTwelve is two what twenty-four is to four.十二比二就等于二十四比四。(2)what C is to D, A is to BWhat food is to the body, a book is to the mind. 书籍对于思想犹如食物对于身体。(3)what C is to D, that A is to BWhat the gun is to a soldier, that the pen is to a writer.作家的笔犹如战士的枪。 巩固练习 请选出符合
