12、 as themselves1.“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”)。e.g.：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。e.g.：1.You may borrow as many books as you can.你能借多少书就借多少。2

13、.“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。e.g.: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”。e.g.:China is larger that any countries in A

14、frica.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”.e.g.: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.我从来没有听过比这更有趣的故事了。5.“形容词+to”结构也可表示比较含义。e.g.：1.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。)2.Li pi

15、ng 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neithernor结构来改写)。e.g.：Im 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 e.g.:This book is not more interesting than that one.这本书不如那本书有

16、趣。(相当于:The book is less interesting than that one.)8.“形容词比较级+than+形容词”,意为:与其倒 不如.e.g.:Jack is much harder than clever.与其说杰克聪明，倒不如说他学习用功。9.would ratherthan,preferto,prefer to dorather 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。e.g.:She would rather die than give in.她宁死不屈。He preferred to go o

17、ut rather than stay home.他宁愿出去也不愿呆在家里。10.“The+比较级比较级，the+比较级比较级”.该结构意为 “越，越”。e.g.：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；就像一样”。what的该类用法 共有3种情况：(1)A is to B

18、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。1.Finish Ex.5 on P59.2.Find and underline the sentences of comparison in the text.!
