11、方式的句子时，先要判断该句是表示与现在、过去、还是将来事实相反，然后依照相应的虚拟语气规则用法的形式来确定句子结构。含有下面三个表达方式的句子体现虚拟语气的形式是固定的：lest(以免，防备),for fear that(惟恐),on condition that(在.条件下)，它们后面句子的谓语动词的形式都是：（should）+动词原形。,二、虚拟语气的特殊应用：,The storm delayed us.But for the storm we would have been in time.I used my calculator;otherwise Id have taken much

15、表达是与什么时态的事实相反上并不一致（比如主句要表达与现在事实相反而从句要表达与过去事实相反），这种情况要采用“对号入座”的方法来处理，即主从句结构分别采用与其表达时态对应的结构。If you had asked him yesterday,you would know what to do now.（从句与过去事实相反，主句与现在事实相反。）If it had rained last night(过去),it would be very cold today(现在).,三、错综时态的虚拟语气：,1.If I hadnt stood under the ladder to catch you

21、o do.,而不能说 Werent I to do.,四、虚拟条件句的倒装：,C,比较级,在四级测试中，比较级属低档题，比较简单，考查范围大体有：1）比较级形式的判断：比较级考题在设计干扰项时一般都会有比较与非比较的选择，more than 与as/so as的选择。The trumpet player was certainly loud.But I wasnt bothered by his loudness _ by his lack of talent.(1999.1)A.than B.more than C.as D.so much asThere are few electroni

24、 as much protein B.twice protein as much twiceC.twice protein as much D.protein as twice much,一、比较级的测试特点：,C,D,A,比较级前加not，表示前者不如后者，与not asas相当；比较级前加no是对两者的否定，意为“和一样不”，与neithernor或“as+相反意义的形容词或副词+as”相当。如：He is not taller than me.他不如我高。He is no taller than me.他同我一样不高。(即一样矮)His English is not better tha

25、n mine.他的英语不如我的英语好。His English is no better than mine.他的英语同我的英语一样不好。(即一样差),not+比较级+than/no+比较级+than,两者均可表示数量，前者表示“仅仅”、“只不过”，强调少；而后者表示“不多于”、“至多”。如：This test takes no more than thirty minutes.这个测验只需30分钟。For thirty years,he had done no more than he had needed to.30年来，他只干了他需要干的工作。He has not more than th

26、ree children.他最多 3 个孩子(有或许还不到 3 个之意)。,no more than与not more than,两者均可用于比较，前者表示对两者都否定，意为“同一样不”(=neither.nor)；而后者则指两者虽都具有某种特征，但程度不同，意为“不如”、“不及”(=not so.as)。如：He is no more a writer than a painter.他不是画家，也不是作家。(=He is neither a painter nor a writer.)This book is not more difficult than that one.这本书不比那本书

27、更难。(This book is not so difficult as that one.),no morethan与not morethan,no less than 与not less than,表示均可表示数量，前者意为“多达”、“有之多”，强调多；后者表示“不下于”、“至少”。如：He paid no less than$10,000 for it.他为此付了10000多美元。He paid not less than$10,000 for it.他为此付的钱不下10000美元。有时两者都可译为“至少”，但no less than语气比not less than要夸张，表示所涉及的数

28、量比预料的要多，其用法可比较其反义结构no more than（只不过，只有），用于强调少。,no more than 与 no lessthan,前者意为“与一样不”，否定两者；而后者则表示“和一样”，肯定两者。如：Shes no more a great singer than I am.他不是优秀歌手，我也不是。Your brother is no less wise than you.你的兄弟跟你一样聪明。,not any more than,Fat cannot change into muscle _ muscle changes into fat.A.any more than
