虚词复习ppt课件介绍

虚词复习ppt课件内容预览:Link words:连词是一种虚词,它不能独立担任句子成分而只起连接词与词,短语与短语以及句与句的作用。从结构上说,英语连接词分两大类:并列连词(coordinating conjunctions)和从属连词(subordinating conjunctions)。1.并列连词用来连接两个或两个以上地位平等且属于同一层次并具有相同句法功能的词、短语(当然包括介词短语了)或句子。如:and,but,or,nor,so,therefore,yet,however,for,hence,as well as,both…and,not only…but also,either…or,neither…nor,(and)then等等。2.从属连词只能用来引导名词从句和各类的状语从句。常见的有:after,although,because,before,if,lest,once,since,that,till,unless,until,when,where,whether,while 等。e.g.He lives where the climate is mild.他住在一个气候温暖的地方并列连词连接两个或两个以上地位平等的字、词组或分句。例如:(1) Air and water are indispensable to me.(2) She likes going out with friends or playing outdoor games.(3) Most workers have a good income,so they look very happy.从属连词连接两个或两个以上的分句,形成复杂句中的从属分句。例如:(4) He said that he did not want to go .(5) Many things have happened since I last saw him.(6) You may come if you want to.上述连词的用法,看起来不难,但错误也难免。下面是些好例子:(1) This book may be used both as a text as well as a reference book.这里的“as well as”和“both”不能搭配,应该将“as well ”改为“and”,使“both.......and......”变成关联连词(correlative conjunction)(2) He not only speaks Mandarin but alsoEnglish.这里的“not only”应该移到“speaks”后面,使这个动词兼顾两个等立宾语:“Mandarin”和“English”。(3) Although he is fat,but he is very weak.英语里的“although”和“but”是不见面的,因此这句里的“but”要去掉,不然“although”就要出来。(4) Jim is not so strong like you.这里的“not so”必须和“as”连成一体;介词“like”是不适宜的。(5) No sooner had we reached our destination,they left."No sooner"必须和"than"配成关联连词,把"than"省掉是不对的,应该补上:No sooner had we reached our destination than they left.这句子的意思也可透过“as soon as”反映出来:“As soon as we reached our destination,they left.”(6) I took a taxi and which took me to the station.这里的并列连词“and”是多余的,必须去掉。如果要保留“and ”也可,但是形容词分句(定语从句)里的关系代词“Which”要改成主语“it”,使整个句子变成并列分句如下:I took a taxi and it took me to the station.(7) My friend came up to me and held my hand,said good-bye excitedly.这里的“and”应该用来连接最后两个谓语才对:My friend came up to me,held my hand,and said good-bye excitedly.不然,就要把“said”改成“saying”。My friend came up to me and held my hand,saying good-bye excitedly
