Why do we clap? To show we like something, of course. 我们为什么要鼓掌?当然是为了表明我们喜欢某事物。本句使用了一个省略回答,补充完整为:We clap to show we like something, of course.这常为一个命题点,有时不仅仅局限在不定式上,有可能还会有其他的动词形式,但是解题方法基本相同,即用还原法把它补充完整。 3. Mr. and Mrs. Harry Blunkett request the pleasure of your company at the wedding of their daughter Elizabeth Ann Blunkett to Mr. Jack Humphries, at St David's Church, Landrindod Wells on Saturday March 5th at 1700, followed by a dinner dance at the Hotel Metropole. 哈里·布伦基特夫妇邀请你参加他们的女儿安·伊丽莎白·布伦基特与杰克·汉弗莱斯的婚礼。婚礼定于3月5号星期三在位于Landrindod Wells的圣·大卫教堂举行。婚礼过后在Metropole旅馆将有一个晚餐舞会。 本句虽然很长,仍然是一个简单句。句中第二个of后的内容作wedding的定语,说明是谁的婚礼,followed by a dinner dance at the Hotel Metropole作wedding的非限制性定语。 其中company这里意思是“陪伴”的意思,而不是“公司”。固定搭配in company with sb.的意思是“和某人一起”。 语法通关 1If与when的用法区别 If引导条件状语从句,when引导时间状语从句 2. 条件状语从句(在条件状语从句中,要用一般时态代替将来时) 常用的引导词有:if(如果,假如),unless(除非,要不就不),as long as(只要),so long as(只要),provided(that)(只要),suppose/supposing(假设),on condition(that)(如果)等。 在表示条件的状语从句中,既可以用直接陈述语气作真实条件句,也可以用虚拟语气作非真实条件句。至于把句子当成哪一种条件句,要依照有关语法规则和表达意思的需要而定。 表示与现在事实相反的假设时,条件状语从句中的谓语动词用过去式(be的过去式用were),而主句的谓语动 表示与将来事实相反的假设时,条件状语从句中的谓语动词用过去式(be的过去式用were),而主句的谓语动词用“were to/should/would动词原形。” 3. 由although; though; whoever; whatever; whenever; wherever引导的让步状语从句 引导词: though, although, as, even if, even though, whatever/no matter what, whenever/no matter when, wherever/no matter where, whoever/no matter who, whichever/no matter which, however/no matter how, no matter whether/if 英语中不允许在though或although从句后用but。如果要强调前后两个部分的对比意义,可以在主句前加上yet或still。 当从句主语与主句主语一致,从句中谓语是be或者从句中主语是it,谓语是be的时候,可以将从句中的主语与be一起省略。 4should 与must的用法区别 Unit 4 Great Scientists重点词汇 Biology; chemistry; genetics; physics; agriculture; breakthrough; support; award; discover; equal; measure; radiation; theory; disease; disability 重点短语 brought up教育,培养 from an early age从很早的时候开始 as a result of由于,原因是 be know for因而著名 because of 因为 come to power掌权 at present目前not everybody不全是;并不都be attached to被系/捆在.上 长难句解析 1.

The shore is the area where the land meets the sea or a lake. 岸就是陆地与海洋或湖泊汇合的地方。 本句中使用了由where引导的定语从句。where既可以引导限制性定语从句,也可以引导非限制性定语从句;where本身在从句中作地点状语,从句的前面不仅可以用表示“地点”的名词作先行词,还可以用表示地点含义的抽象名词作先行词。where有时相当于“介词关系代词”。 2. A lake is an area of water surrounded by land. 湖泊就是由陆地所围成的一片水域。 本句使用了过去分词短语作后置定语,相当于定语从句which is surrounded by land,其具体用法如下: 1) 过去分词作定语常常位于其所修饰的名词前;过去分词短语作定语时,常常位于其所修饰的名词后,相当于一个定语从句。 3. He and a colleague were to spend two years there teaching English at a teacher training college. 他和一位同事将在那里的一所教师进修学院教两年英语。 本句使用了be to do sth.表示“按照计划或根据安排将要进行某个动作”。 4. On a distant mountain was a sign in 20-foot characters. 远山上写着20英尺大的汉字。 本句中由于地点状语放在了句首,且主语是名词a sign,所以使用了完全倒装。 5. And everywhere he goes, he sends himself a postcard. 每到一处他都给自己寄一张贺卡。 本句是由everywhere引导的地点状语从句,表示强调 语法通关 情态动词 情态动词的语法特征 情态动词表示某种感情和语气,不能单独作谓语,必须和其他动词一起构成谓语。 情态动词没有人称、数的变化,后面只能接不带to的不定式。 词义 现在式过去式同义短语cancouldbe able tomaymight/must/have toshallshouldought towillwould/need/daredared/(一) 情态动词表推测1) 形式肯定的推测:must否定的推测:cant couldnt可能的推测:may might can could疑问的推测:can could2) 时间对过去:情态动词+完成式(have donehave been done)对正在进行:情态动词+be doing对现在或将来:情态动词+do不同的“肯定”程度可按下列层次排列: He is at home.

You ought to get him to receive good education.6. shouldshall(1)shall1)在疑问句中,shall用于征求对方的意见或请求指示,常用于第一、第三人称。Shall we go out for a walk? 2)shall作为情态动词用于第二、三人称,表示说话人的意愿,有“命令”、“警告”、 “威胁”和“允诺”等意思。如: You shall fail if you don't work harder.

Should I be free tomorrow, Ill come. If things should change suddenly, please let me know4).用于疑问句或感叹句中,表示意外、惊异的情绪,意为“竟会”,与why,whatWhy should anyone want to marry Tony?Dont ask me. How should I know?(三) 情态动词+完成式表示“本却”might have done表示“本来可能,但实际上没有发生的事情”。另外,还可以表示“本来应该或可以做某事”之意,含有轻微的责备语气。should/ought to have done 表示本该做某事,而实际上未做;用于否定句时,则表示不该做的事反而做了could have done用于肯定句中,表示“可能已经”之意,此外,还可以表示过去能做而没做的事,有一种对过去为付诸实施的事情的惋惜。neednt have done表示做了本来不必去做的事。注意:didnt need to do表示“没必要做而实际上也没有做某事would rather have done表示“当时宁愿做了某事”,其否定式would rather not have done表示相反的含义,两者都表示“后悔”之意。had better have done用于事后的建议,含轻微责备的口吻,意为“当时最好做了某事”,其否定式had better not have done表示相反的含义。(五)情态动词的反义疑问句1当陈述句部分有情态动词must时(1)must表示“必须、禁止“时,反意疑问部分要用must (mustnt) 。 You mustnt stop your car here, must you?You mustnt do that again, must you?(2)must表示“有必要”时,反意疑问句部分要用neednt。 They must finish the work today, neednt they? You must see the doctor, neednt you?(3)当must用来表示对现在的情况进行“推测”时,反意疑问部分要根据must后面的动词采用相应的形式。 He must be good at maths, isnt he? (4)当must用来表示对过去的情况进行“推测”(must + have done)时:a). 单纯表示对过去的推测, 与现在无关, 反意疑问句附加部分用过去式。b). 表示对过去的推测且影响到现在或持续现在, 反意疑问句附加部分用现在完成式。 She must have read the novel last week, didnt she?
