（通用版）2019中考英語二輪復習 連詞講義

連詞學員姓名： 年 級： 輔導科目：英語 學科教師：授課日期授課時段授課主題連詞 教學內(nèi)容課前回顧知識梳理知識點1：連詞連詞是一種虛詞，不能擔任一個句子成分。它主要是包括并列連詞和從屬連詞。2.1 并列連詞1.并列連詞的功能：連詞在句中主要起連接詞與詞、短語與短語及句子和句子的作用。即，連接兩個平行的成分或句子。如：and, but, or, nor, so, therefore, yet, however, for, as well as, bothand, not onlybut also, eitheror, neithernor, (and)then等等。2.并列連詞的用法表示連接兩個共同概念and和or1)并列結構中，or通常用于否定句，and用于肯定句。2)但有時and也可用于否定句。請注意其不同特點：There is no air or water in the moon.There is no air and no water on the moon.在否定中并列結構用or連接，但含有兩個否定詞的句子實際被看作是肯定結構，因此要用and。bothand兩者都 (兩者都強調(diào)，謂語動詞為復數(shù))not onlybut (also),不但而且 (強調(diào)后者，就近原則)注意： not only but also關聯(lián)兩個分句時，一個分句因有否定詞not而必須倒裝。Not only does he like reading stories, but also he can even write some.neithenor意思為"既不也不" (就近原則)Neither you nor he is to blame. as well as 也 (強調(diào)前者，就遠原則) The students as well as their class teacher like watching football matches very much.I have one of his plays as well as a few of his novels.表示選擇的并列結構 1) or意思為"否則"。 I must work hard, or I'll fail in the exam.2) eitheror意思為"或者或者"。注意謂語動詞采用就近原則。Either you or I am right.表示轉折或?qū)Ρ?) but表示轉折，while表示對比。some people love cats, while others hate them.2) notbut 意思為"不是而是"not和but后面的用詞要遵循一致原則。They were not the bones of an animal, but (the bones) of a human being.表示因果關系1) forfor是并列連詞，不能置于含兩個并列分句的句子的句首，只能將其放在兩個分句中間。2) so, thereforeHe hurt his leg, so he couldn't play in the game.備注：a.兩個并列連詞不能連用，但therefore, then, yet.可以和并列連詞連用。You can watch TV, and or you can go to bed.He hurt his leg, and so / and therefore he couldn't play in the game.b. although yet，但although不與 but連用。 (錯)Although he was weak, but he tried his best to do the work. (對)Although he was weak, yet he tried his best to do the work. 比較so和 such其規(guī)律由so與such的不同詞性決定。such是形容詞，修飾名詞或名詞詞組，so是副詞，只能修飾形容詞或副詞。so還可與表示數(shù)量的形容詞many，few，much， little連用，形成固定搭配。2.2從屬連詞1.引導賓語從句的從屬連詞有三個：that (無詞義，可省略)；whether (是否)，可與“or (not) ”連用；if(是否)。它們在從句中都不作成分。在ask,wonder,not know,want to know,not be sure等后常用whether或if從句，而不用that從句。2.引導狀語從句的從屬連詞：從句種類主要從屬連詞 時間從句 when, while, as, before, after, until, till, whenever 條件從句 if, unless 目的從句 in order that, so that 結果從句 sothat, suchthat, so that, so 原因從句 because, as, since 讓步從句 although, though, even though(if), while 方式從句 as if, as though 地點從句 where, wherever 比較從句 than, as常用連詞的用法辨析1 while, when, as這三個連詞都可引導時間狀語從句，但用法有所不同。1) 當某事正在進行的時候，又發(fā)生了另一件事。While, when, as 都可用來引導表示“背景”的時間狀語從句。例如：As/When/While I was walking down the street I noticed a police car.2) 當兩個長動作同時進行的時候，最常用的是while。例如：While mother was cooking lunch, I was doing my homework.3) 當兩個動作都表示發(fā)展變化的情況時，最常用的是as。例如：As children get older, they become more and more interested in things around them.4) 當兩個短動作同時發(fā)生時，或表示“一邊一邊”時，最常用as。例如：Just as he caught the fly, he gave a loud cry.She looked behind from time to time as she went5) 當從句的動作先于主句的動作時，通常用when。例如：When he finished his work, he took a short rest.6) 當從句是瞬間動作，主句是延續(xù)性動作時，通常用when。例如：When John arrived I was cooking lunch.2.as, because, since , for這四個詞都可表原因，但用法有區(qū)別。1) 如果原因構成句子的最主要部分，一般用because。因此，because引導的從句往往放在句末。例如：I stayed at home because it rained.-Why arent you going?-Because I dont want to.2) 如果原因已被人們所知，或不如句子的其它部分重要，就用as或since。Since比as稍微正式一點。As和since 引導的從句一般放在句子的開頭。例如：As he wasnt ready, we left without him.Since I have no money, I cant buy any food.3) for用來補充說明一種理由，因此，for引導的從句幾乎可以放在括號里。For引導的句子不放在句子的開頭。例如：I decided to stop and have lunch-for I was feeling quite hungry.3.if, whetherif和whether都可作“是否”講，在引導賓與從句是一般可互換。例如：I wonder whether (if) you still study in that school.I dont know whether (if) he likes that film.在下列情況下，只能用whether,不能用if：1) 引導主語從句時。例如：Whether he will come to the party is unknown. 2) 引導表語從句時。例如：The question is whether I can pass the exam.3) 在不定式前。例如：I havent made up my mind whether to go there or not.4.sothat, such.that1) sothat中的so是個副詞，其后只能跟形容詞或副詞，而such.that中的such是個形容詞，后接名詞或名詞短語。例如：Im so tired that I cant walk any farther.It was such a warm day that he went swimming.2) 如果在名詞之前有many, much, little, few時，用so,不用such。例如：He has so little education that he is unable to get a job.I have had so many falls that I am black and blue all over.5.eitheror, neithernor, not onlybut also這三個連詞詞組都可連接兩個并列成分。當它們連接兩個并列主語時，謂語動詞要隨相鄰的主語變化。例如：Either you or he is wrong.Neither he nor his children like fish. Not only the teacher but also the students want to buy the book.6.although, but這兩個連詞不能用在同一個句子中。例如：我們不能說“Although he is over sixty, but he works as hard as others.”這個句子應改為：Although he is over sixty, he works as hard as others.或He is over sixty, but he works as hard as others. 7.because, so這兩個連詞同樣不能用在同一個句子中。例如：我們不能說“Because John was ill, so I took him to the doctor.” 這個句子應改為Because John was ill, I took him to the doctor.或John was ill, so I took him to the doctor.3定語從句、名詞性從句也有其自己相應的從屬連詞，這個在高中會詳細講解，這里不展開。隨堂練習：1.
