27、at has irrevocably altered astro no mists ideas about the orig ins of the universe、than常见语法难点讲解Than在不同情况下得用法、后接人称代词用主格还就是宾格由于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:Everyo ne here is taller than I me、这儿得每一个人都比我高。Her sister swims faster than she her她姐姐游泳比她快。但就是，若人称代词之后跟

28、有动词，则只能用主格。如:Every one here is taller than I am这儿得每一个人都比我高。注意：有时用主格或宾格会导致意思得变化。比较:I love you more tha n he (likes you)我比她更爱您。I love you more than (he likes) him我爱您胜过爱她。二、后接动词用不定式还就是动名词当连接两个非谓语动词时，诵常应使用一样得形式。如:It is much easier to get into debt tha n to get out of it、借债容易还债难。He likes playing chess mo

29、re than watching TV与瞧电视相比，她更喜欢下棋。比较:He thinks it is safer to drive himself than (to) let me drive、=He thinks that driving himselfis safer than lett ing me drive、她认为她自己开车比让我开车要更安全些。2、若不就是连接两个非谓语动词，则其后出现得动词通常用动名词形式（虽然也可用不定式，但不如用动名词普通）。如：There are worse calamities than failing your driving test比起您驾驶考试不

30、合格来 说，更大得灾难还多着呢。Nothi ng gives me more pl easure tha n liste ning to Mozart再没有比听莫扌L特得乐 曲更让我高兴得事了。1、Noth ing is more unp leasa nt tha n finding to find in sects in your bath、最使人不快得就是在浴室里发现有虫子。三、引导比较状语从句得时态问题若than引导得比较状语从句与主句动作不一致， 可以根据情况使用适当得时态 形式。 如：He drives faster tha n he did a year ago她开车比一年以前快了

31、。The house is rather bigger than we thought这所房子比我们想得大得多。若主句为将来时,than引导得从句可用现在时态表示将来，也可直接使用将来 时态。如：Wel probably drive faster than you do will、 我们开车可能会比您们快。四、引导比较状语从句得倒装问题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 has a higher death rate tha n country people does =City dweller has a highe

32、r deathrate than does country people城市居民死亡率比 农村居民咼。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 don twa nt to do more tha n is n ecessaryt我们不想做不必要得事情。The pain was almost more tha n he could beat这样得痛苦几乎使她受不了。Shenot a very good manager she always spends more money than

33、 she earn、她 不大会理财一一总就是入不敷出。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后得expected为省略结构:He retur ned three days earlier tha n (he was) expected她回来得比预料得要早三 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引导得时间状语从句 以及L引导得条件状语从 句。如：You are a little fatter than whe n I saw you last您比我上次见您时胖点了。J

34、oe carries only nine pounds more than when he was twenty乔比她20岁时只重 了九磅。They work better together than if they are alone、 她们一起干比她们单干效果要 好。七、同质比较还就是异质比较than通常用于两个不同得人或物在同一方面进行比较，但有时指得可能就是同 _ 一个人或物在两个不同得方面进行比较，此时只用于moretha n结构，而不 能用-erthan得形式(即使就是单音节也就是如此)，这类结构通常可译为“与其不如”“有无”。如：Hesmore fat than short、与其

35、说她矮不如说她胖。They are more brave tha n wise她们有勇无谋。If we tell him about it, it may do more harm tha n good、 倘若我们把情况告诉她, 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)得比较级结构连用，表示强调，通常表示最高级得含 义。如：Ie n ever had a worse morni ng tha n today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 fin e, never better、她很好，比

36、以往任何时候都好。Ie n ever see n a finer bird我从未见过比这更美得鸟。Ie never fou nd a better job、这就是我找到得最好得工作。九、than any other后接名词用单数还就是复数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她比班上得其她任何学生都游 得快。More heat is lost through the head tha n any other part of the body、 从头部散发得 热量

37、比身体得其她任何部位都多。十、几组容易理解出错得than习语“ 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得反义词用于asas结构。如：He is no richer than a beggar =He is as poor as a beggar她穷如乞丐。This one is no better than that one、=This one is as bad as that one这个与那个一 样不好。“not +比较级+than”得意思就是“不比更”“不如”。如:He is n ot richer than you她不如您富有。1、This one is not better tha n that one、 这个不如那个好。no less than, no less、than与not less than(1) no less than有两个意思：一就是表示“多达”“有 之多”，强调数量之 多；二就是表示“简直”“与没有差别”。如：We walked no less tha n three miles我们走了三英里之远。We won no less
