Book Module 2 Grammar Link words,Dai Tao,2012-4-10,连词，就像是链接我们人体关节中的韧带一样，试想：如果关节没有了韧带的链接，那会发生什么可怕的结果,如果我们的英语句子也同样失去了连词的“链接”，那么，试想一下又将发生什么可怕的场景,来，感受下没有连词的“可怕结果”！ 1. 他很生气，但是他却控制住了自己。 He was very angry _he controlled himself. 2. 你可能是对的，然而，我仍想做我承诺过的事儿。 You may be right. _, I still want to do what I promised. 3. 我喜欢流行音乐， 而他却喜欢古典音乐。 I like pop music, _ he likes classical music. 4. 虽然他很喜欢这个女孩，但是他却不能娶她。 _ he likes the girl very much, (and yet/ still) he cant marry her.,but,However,while,Although,自我探究：,以上各句中都使用了连词，but表示转折；however意为“然而”，做连词引导状语从句，意为“可是”；while表示前后对比，意为“而”；although引导让步状语从句，意为“虽然”，但不能和but连用,连 词,连词就是把两个或两个以上相关的单句组合起来的词语。连词用来连接词、短语、从句或是句子，是一种虚词，不能单独做句子成分；连词可以是句子与句子练习比较紧凑，因而使得上下文更加连贯。 我们已学过的引导时间状语从句的连词有when，while，as等；引导原因状语从句的连词有because，since，as等；引导条件状语从句的连词有if，unless等。 下面我们来比较两对连词，它们都表示前后之间是转折或对比转折的关系。,一、but与however 注意but与however的区别: 首先，however的位置比较灵活，常用逗号“,”与主句隔开，而but通常不用；其次，but常用于I m sorry/ Excuse me, but中，而however不可以。 but 表示转折、对比、对照，语气最强，常位于句子的开头。 他的母亲不会在那儿，但他的父亲也许会在。 His mother wont be there _ his father might.,but,口语中，在上下文语境中会用于句首。 “我从报纸上读到的这则消息。” “但是报纸并不总是正确的” “I read it in a newspaper.” “_newspapers are not always right” 很抱歉，但我不能帮你解决这个问题。 Im sorry, _I cant help you with the problem.,But,but,2. however 作连词时，其引导的从句放在主句前，也可放在主句后，表示“可是”。另外，however常用作副词，表示“然而”，这时，however可以位于句首、句中、句末，但必须有逗号与主句隔开。However还可表示“无论如何”. 他感觉不舒服，可是他仍然去上班，并努力 集中精力。 He was feeling bad. He went to work,_, and tried to concentrate. 他们很努力工作，然而没有完成任务。 They had worked hard._, they didnt finish the task.,however,However, 无论多么晚，他的家人总是等他一起吃晚饭。 _ late he is, his family will wait for him to have dinner together. 无论有多少工作需要做，你都应该尽量睡个好觉. You should try to get a good nights sleep _ much work you have to do. 二、while与although 1. While可作从属连词，表示“虽然”，此时可与although互换。While可作并列连词，表“然而”强调前后是对比的关系，所以引导的句子不能位于句首。,However,however, 虽然我没有见过他，我一直把他当作我的好朋友. _ I havent seen him, I have regarded him as my good friend. 我做所有的家务，而我丈夫鲍勃只是偶尔涮涮碗. I do all the housework _ my husband Bob just does the dishes every now and then.,While/ Although,while,2. although表“虽然”，引导从句时绝不能与but共用，但可与still，yet连用。 尽管她不喜欢她的继母，但为了她父亲的那份爱，她还是时常去看望她。 _ she hates her stepmother, she still goes to see her for the love of her father at times. 他们虽然傲慢，但他们怕见我。 _ they are proud, they are afraid to see me.,Although,Although,课本拾遗：,1.
