Book Module 2 Grammar Link words,Dai Tao,2012-4-10,連詞，就像是鏈接我們?nèi)梭w關(guān)節(jié)中的韌帶一樣，試想：如果關(guān)節(jié)沒有了韌帶的鏈接，那會發(fā)生什么可怕的結(jié)果,如果我們的英語句子也同樣失去了連詞的“鏈接”，那么，試想一下又將發(fā)生什么可怕的場景,來，感受下沒有連詞的“可怕結(jié)果”！ 1. 他很生氣，但是他卻控制住了自己。 He was very angry _he controlled himself. 2. 你可能是對的，然而，我仍想做我承諾過的事兒。 You may be right. _, I still want to do what I promised. 3. 我喜歡流行音樂， 而他卻喜歡古典音樂。 I like pop music, _ he likes classical music. 4. 雖然他很喜歡這個女孩，但是他卻不能娶她。 _ 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連詞，but表示轉(zhuǎn)折；however意為“然而”，做連詞引導(dǎo)狀語從句，意為“可是”；while表示前后對比，意為“而”；although引導(dǎo)讓步狀語從句，意為“雖然”，但不能和but連用,連 詞,連詞就是把兩個或兩個以上相關(guān)的單句組合起來的詞語。連詞用來連接詞、短語、從句或是句子，是一種虛詞，不能單獨做句子成分；連詞可以是句子與句子練習(xí)比較緊湊，因而使得上下文更加連貫。 我們已學(xué)過的引導(dǎo)時間狀語從句的連詞有when，while，as等；引導(dǎo)原因狀語從句的連詞有because，since，as等；引導(dǎo)條件狀語從句的連詞有if，unless等。 下面我們來比較兩對連詞，它們都表示前后之間是轉(zhuǎn)折或?qū)Ρ绒D(zhuǎn)折的關(guān)系。,一、but與however 注意but與however的區(qū)別: 首先，however的位置比較靈活，常用逗號“,”與主句隔開，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 表示轉(zhuǎn)折、對比、對照，語氣最強，常位于句子的開頭。 他的母親不會在那兒，但他的父親也許會在。 His mother wont be there _ his father might.,but,口語中，在上下文語境中會用于句首。 “我從報紙上讀到的這則消息?！?“但是報紙并不總是正確的” “I read it in a newspaper.” “_newspapers are not always right” 很抱歉，但我不能幫你解決這個問題。 Im sorry, _I cant help you with the problem.,But,but,2. however 作連詞時，其引導(dǎo)的從句放在主句前，也可放在主句后，表示“可是”。另外，however常用作副詞，表示“然而”，這時，however可以位于句首、句中、句末，但必須有逗號與主句隔開。However還可表示“無論如何”. 他感覺不舒服，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. 他們很努力工作，然而沒有完成任務(wù)。 They had worked hard._, they didnt finish the task.,however,However, 無論多么晚，他的家人總是等他一起吃晚飯。 _ late he is, his family will wait for him to have dinner together. 無論有多少工作需要做，你都應(yīng)該盡量睡個好覺. You should try to get a good nights sleep _ much work you have to do. 二、while與although 1. While可作從屬連詞，表示“雖然”，此時可與although互換。While可作并列連詞，表“然而”強調(diào)前后是對比的關(guān)系，所以引導(dǎo)的句子不能位于句首。,However,however, 雖然我沒有見過他，我一直把他當(dāng)作我的好朋友. _ I havent seen him, I have regarded him as my good friend. 我做所有的家務(wù)，而我丈夫鮑勃只是偶爾涮涮碗. I do all the housework _ my husband Bob just does the dishes every now and then.,While/ Although,while,2. although表“雖然”，引導(dǎo)從句時絕不能與but共用，但可與still，yet連用。 盡管她不喜歡她的繼母，但為了她父親的那份愛，她還是時常去看望她。 _ she hates her stepmother, she still goes to see her for the love of her father at times. 他們雖然傲慢，但他們怕見我。 _ they are proud, they are afraid to see me.,Although,Although,課本拾遺：,1.
