15、越”，前者相当于一个条件句，因此，要用一般现在时代替一般将来时。如(from .com)：The harder you work, the better result youll get.你学习越努力，成绩就越好。(3) the+比较级(+of the two)：表示“两者中较的那个人或物”。如：Tom is the taller of the two brothers.汤姆是两兄弟中个子较高的那个。(4) 比较级+and+比较级：表示“越来越”，单音节形容词或副词用“-er+and +-er”，如warmer and warmer越来越暧和；多音节形容词或副词用“more and more”

21、an his brother.他比他兄弟大三岁(from .com)。三、最高级前可用the second, the very, much the, (by) far the, not quite the, nearly the, almost the等修饰。如：She is by far the most active member in our group. 她是我们组最最活跃的成员。Africa is the second largest continent.非洲是第二大洲。This hat is nearly/almost the biggest. 这帽子差不多是最大的了。注意：ver

22、y和much修饰最高级时的不同位置。This is the very best. =This is much the best.这是最最好(难)的。4)倍数可以放在asas的第一个as前作修饰语。如：Their house is about three times as big as ours. 他们的房子大约有我们房子三倍大。与比较级相关的习语(1) no more than =only只有，仅仅，只不过There are no more than a hundred people in the hall.大厅里只有100人。(2) not more than=at the most不超过，

27、形容词最高级前通常用the，副词最高级前的the可以不用。(2) 形容词最高级作表语时，有时可以省略the。如：Which of the boys is (the) strongest?这些孩子中哪个最强壮？(3) 最高级形容词作表语，副词用状语时，没和别人比较时不用the。如：Hes busiest on Monday.他星期一最忙。He works hardest when doing something for his family.他为自己家做事时最卖力。(4) 最高级前已有名词所有格或物主代词时，不用the。如：He is my best friend.他是我最好的朋友。 Haina

28、n is Chinas second largest island. 海南是中国第二大岛。(5) 有时most是表示“非常”，而不是最高级，不用the。如：He is a most amazing person. 他是一个非常了不起的人。使用than的常见语法难点一、后接人称代词用主格还是宾格由于than既可用作连词也可用作介词，所以当后接人称代词时，可用主格也可用宾格。通常认为在正式文体中多用主格，在口语或非正式文体中多用宾语。如：Everyone here is taller than I me. 这儿的每一个人都比我高。Her sister swims faster than she h

29、er. 她姐姐游泳比她快。但是，若人称代词之后跟有动词，则只能用主格。如：Everyone here is taller than I am. 这儿的每一个人都比我高。Her sister swims faster than she does. 她姐姐游泳比她快。注意：有时用主格或宾格会导致意思的变化。比较：I love you more than he (likes you). 我比他更爱你。I love you more than (he likes) him. 我爱你胜过爱他。二、后接动词用不定式还是动名词1. 当连接两个非谓语动词时，通常应使用一样的形式。如：It is much ea

30、sier to get into debt than to get out of it. 借债容易还债难。He likes playing chess more than watching TV. 与看电视相比，他更喜欢下棋。比较：He thinks it is safer to drive himself than (to) let me drive. =He thinks that driving himself is safer than letting me drive. 他认为他自己开车比让我开车要更安全些。2. 若不是连接两个非谓语动词，则其后出现的动词通常用动名词形式(虽然也可用

31、不定式，但不如用动名词普通)。如：There are worse calamities than failing your driving test. 比起你驾驶考试不合格来说，更大的灾难还多着呢。Nothing gives me more pleasure than listening to Mozart. 再没有比听莫扎特的乐曲更让我高兴的事了。 Nothing is more unpleasant than finding to find insects in your bath. 最使人不快的是在浴室里发现有虫子。 三、引导比较状语从句的时态问题若than引导的比较状语从句与主句动作不

32、一致，可以根据情况使用适当的时态形式。如：He drives faster than he did a year ago. 他开车比一年以前快了。 The house is rather bigger than we thought. 这所房子比我们想的大得多。 若主句为将来时，than引导的从句可用现在时态表示将来，也可直接使用将来时态。如：Well probably drive faster than you do will. 我们开车可能会比你们快。 四、引导比较状语从句的倒装问题than引导比较状语从句时，从句语序通常不需倒装，但在正式文体中，有时也可倒装。如：City dweller

33、 have a higher death rate than country people do. =City dweller have a higher death rate than do country people. 城市居民死亡率比农村居民高。 五、引导比较状语从句且在从句中充当成分有时可引导一个从句并在从句中充当句子成分(主语、宾语、表语)，为便于理解有时可视为than后省略了what：We dont want to do more than is necessary. 我们不想做不必要的事情。The pain was almost more than he could bear.

34、 这样的痛苦几乎使他受不了。Shes not a very good manager she always spends more money than she earns. 她不大会理财总是入不敷出。 Life here is much easier than it used to be. 如今在此地生活比起从前可舒服多了。比较下面一句，than后的expected为省略结构：He returned three days earlier than (he was) expected. 他回来得比预料的要早三天。六、后接时间或条件状语从句若语义需要，有时其后可接when引导的时间状语从句以及i

35、f 引导的条件状语从句。如：You are a little fatter than when I saw you last. 你比我上次见你时胖点了。 Joe carries only nine pounds more than when he was twenty. 乔比他20岁时只重了九磅。 They work better together than if they are alone. 他们一起干比他们单干效果要好七、同质比较还是异质比较than 通常用于两个不同的人或物在同一方面进行比较，但有时指的可能是同一个人或物在两个不同的方面进行比较，此时只用于morethan结构，而不能用

36、 erthan的形式(即使是单音节也是如此)，这类结构通常可译为“与其不如”“有无”。如：Hes more fat than short. 与其说他矮不如说他胖。They are more brave than wise. 他们有勇无谋。If we tell him about it, it may do more harm than good. 倘若我们把情况告诉他，那可能弊多利少。八、与never (a) 连用时如何理解有时than与带有never (a) 的比较级结构连用，表示强调，通常表示最高级的含义。如：Ive never had a worse morning than today

37、. 我哪一天早上也不像今天早上这样倒霉。 若意思明确，有时可省略than结构。如：He is fine, never better. 他很好，比以往任何时候都好。Ive never seen a finer bird. 我从未见过比这更美的鸟。Ive never found a better job. 这是我找到的最好的工作。九、than any other后接名词用单数还是复数than any other后接名词时通常用单数形式，很少用复数。如：He swims faster than any other student in his class. 他比班上的其他任何学生都游得快。More

38、heat is lost through the head than any other part of the body. 从头部散发的热量比身体的其他任何部位都多。十、几组容易理解出错的than习语1.“no +比较级+than”与“not +比较级+than”(1) “no +比较级+than”用于否定两者，表示“与一样不”，其义大致相当于其中形容词或副词的反义词用于asas结构。如：He is no richer than a beggar.=He is as poor as a beggar. 他穷如乞丐。This one is no better than that one.=Th

39、is one is as bad as that one. 这个与那个一样不好。(2) “not +比较级+than”的意思是“不比更”“不如”。如：He is not richer than you. 他不如你富有。This one is not better than that one. 这个不如那个好。2. no less than, no less.than 与 not less than(1) no less than 有两个意思：一是表示“多达”“有之多”，强调数量之多；二是表示“简直”“与没有差别”。如：We walked no less than three miles. 我们

40、走了三英里之远。We won no less than 500 in a competition. 我们在一次比赛中就赢了500英镑。It is no less than robbery to ask for so much. 要这么多，简直跟抢劫没什么两样。(2) no less.than 意为“与一样”“不比差”，强调两者具有同等性。如：He is no less wise than you. 他跟你一样聪明(他并不比你笨)。A dolphin is no less a clever animal than a dog is. 海豚与狗同样都是聪明的动物。(3) not less than

41、 意为“不下于”“至少”。比较：He has no less than seven daughters. 他有七个女儿之多。He has not less than seven daughters. 他至少有七个女儿。3. no more than, no morethan与not more than(1) no more than表示“仅仅”“只有”“只不过”，强调程度低或数量少。如：He is no more than an ordinary English teacher. 他只不过是个普通的英文老师。He has no more than three shirts. 他只有3件衬衫。(

42、2) not more than 表示“至多”，与at most同义。如：He has not more than three shirts. 他最多只有3件衬衫(含有或许还不到3件之意)。(3) no more.than 表示对两者都否定, 意为“既不也不”“同一样不”。如：He is no more a writer than a painter. 他既不是画家，也不是作家。A whale is no more a fish than a horse is. 如同马不是鱼一样，鲸也不是鱼。有关比较等级重要考点一、考查比较等级的基本用法1. Of the two sisters, Betty

43、 is _ one, and she is also the one who loves to be quiet. (安徽卷)A. a youngerB. a youngest C. the youngerD. the youngest【解析】答案选C。根据句中的of the two sisters可知，此题涉及的是两者比较，故用比较级；另外，由于是特指两者中的一个，故其前用定冠词，不用不定冠词。2. Of the two coats, Id choose the _ one to spare some money for a book. (四川卷)A. cheapestB. cheaper

44、C. more expensiveD. most expensive【解析】答案选B。因是两者比较，故用比较级，可将答案锁定在B和C之间；再根据句意，排除C。3. Speaking of all the songs he has written, I think this is probably his _ one. (全国卷II)A. better-knownB. well-known C. best-knownD. most-known【解析】答案选C。因为是从他所写的所有歌中选出一首来比较，故用最高级。二、在语境中考查比较等级的用法1. I dont think this film is

45、 by far the most boring. I have seen _. (江西卷)A. better B. worse C. the bestD. the worst【解析】答案选B。既然前文说“这不是最最烦人的电影”，那么下文说的肯定就“还有更糟的”，故用worse。有意思的是，2006年的这道江西卷的考题与下面这道2004年的湖南卷极为相似：That doesnt sound very frightening. Paul, Ive seen _. What did you like most about the film? A. better B. worse C. best D. worst由前句“这听起来并不十分令人恐惧”可知，说话人曾见过比这个更令人恐惧的事，所以用比较级worse。2. The new group of students is better-behaved than the other group who stayed here _. A. earlyB. earlierC. earliestD. the earliest【解析】答案选B。做此题的关键词是new，即把“新来的学生”与“早些时候呆在这儿的学生”进行比较。全句意为：新来的这群学生比早些时候呆在这儿的那
