1、零基础自学学英语连词的定义：连词是连接字、短语、从句与句子的词，是虚词，因此它不能 独立担当句子成分。连词主要分为两大类：并列连词和从属连词。并列连词用来连接并列关系的词、词组或分句。它包括：and, or, but, so, for, bothand, eitheror, neithernor, not onlybut also0从属连词用来引导从句，它包括：that, when, till, until, after, before, since,because, if, whether, though, although, sothat, so that, in order that,
2、as soon as并列连词用来连接具有并列关系的词，短语 或句子。常见的并列连词有：(1) 表并列关系的 and, bothand, not onlybut also, neithernor 等。(2)表选择关系的or, eitheror等。(3)表转折关系的but, while等。(4)表因果关系的for, so等。1并列连词1 and：和， 并且 I like basketball, football and table-tennis. 我 began learning English two years ago. 自从两年前我起先学习英语 以来，我已经学习了两千多个英语单词了。留意si
3、nce引导的是一个过去时的句子，说明自当时以来到现在 (自从两年前以来)，主句一般要用现在完成时。As soon as I get enough money, I 11 buy it.我一得至ll足够的钱，就买它。3 because：因为，连接缘由状语从句 She didn, t go there, because she was ill.因为她病了，所以她没去那儿。1 .回答Why问句时，只能用because,不能用for或as. Why are you late? 你为什么迟至U? Because I met a traffic accident on my way here.因为在我来这
4、儿的路上，遇到了车祸。2 .汉语中，我们常常说因为所以，但在英文中有了 because,就 不能再用SOo3 ) Because he was tired, so he couldn t walk there. 因 为他累了，所以他不能走到那儿了。4 if, though (although) If it doesn, t rain, we 11 go to the park.假如不下雨，我们就去公园。Though I was tired, I still worked hard. 虽然我很累， 可 是我仍旧努力地工作。1. if：假如(引导条件从句) You can pass the exa
5、m if you study hard.假如你努力学习，你会及格的。2. though, although：虽然（引导让步状语从句）和缘由状语从句一样，假如用了 though, although （虽然）就不能再用but （但是）。Although （Though） I live near the sea, I m not a good swimmer. =1 live near the sea, but I m not a good swimmer. 虽 然我住在海边，可是我游泳并不好。留意留意时态一样，和时间状语从句一样。主句是将来时之时，从句要用一般现在时。5. sothat：太以致 H
6、e is so old that he can, t work. 二 He is too old to work.他太老了，不能工作。The box is so heavy that I can, t lift it. 二The box is too heavy for me to lift.箱子太沉了，我抬不起来。The girl is so beautiful that everybody likes her. 这个小 女孩太美丽了，每个人都喜爱她。留意留意此句型与tooto的互换。sothat在确定句中不能转换成tootOo三 连词比较land与or 1）并列结构中，or通常用于否定句,
7、 and用于确定句。2）但有时and也可用于否定句。请留意其不同特点：There is no air or water in the moon.There is no 含有两个否定词的句子实际被看作是确定结构，因此要用andoair and no water on the moon.在否定中并列结构用or连接，但典型例题 1 don t like chicken fish. 1don t like chicken,I like fish very much. A. and； and B. and； but C. or； but D. or； and 答案 Co否定句中表并列用or, but表转
8、折。推断改错：（错） We will die without air and water. （错） We can t live without air or water. （对） We will die without air or water. （对） We can t live without air and water. 3 ）表示选择的并列结构 （1） or意思为否则。I must work hard, or I 11 fail in the exam. （2） eitheror意思为或者或者。留意谓语动词采纳就近原则。Either you or I am right. 推断改错：（错
9、） They sat down and talk about something. （错） They started to dance and sang. （错） I saw two men sitting behind and whisper there. （对） They sat down and talked about something. （对） They started to dance and sing. （对）I saw two men sitting behind and whispering there.角军析：第一句：and连接两个并列的谓语，所以talk应改为talke
10、d。其次句：and连接两个并列的动词不定式，其次个不定式往往省略to,因此sang应改为singo第三句：and连接感观动词saw后面的用作的宾补的两个并列分词结构，因 止匕 whisper 应改为 whispering。留意：and还可以和祈使句或名词词组连用表示条件。（or 也有止匕用法）Make up your mind, and you 11 getthe chance. = If you make up your mind, you 11 get the chance. One more effort, and you 11 succeed. = If you make one mo
11、re effort, you， 11 succeed. II but 表示转折， while 表示对比。Some people love cats, while others hate them. 典 型例题 Would you like to come to dinner tonight? Id like to, I m too busy. A. and B. so C. as D. but 答案Dobut与前面形成转折，符合语意。而表并列的and,结果的so,缘由的as都不符合句意。III so, therefore He hurt his leg, so he couldn t play
12、 in the game. 留意：a. 两个并列连词不能连用，但therefore, then, yet.可以和并列连词连用。You can watch TV, and or you can go to bed.He hurthis leg, and so / and therefore he couldn t play in the game.b. although yet, 但 although 不与 but 连用。(错) Although he was weak, but he tried his best to dothe work.(对) Although he was weak,
13、yet he tried his bestto do the work. IV 比较so和such其规律由so与such的 不同词性确定。such是形容词，修饰名词或名词词组，so是副词，只能修饰形 容词或副词。little 连用,so还可与表示数量的形容词many, few, much,形成固定搭配。so + adj.+ n. such + n.(pl.(pl. ) so + adj.such + a(n) + n.) so + adj. + n.+ n.不行数suchso + adj. + a(n) (pl. ) such +n. +n.不行数sofoolishsuchfoolso nic
14、ea flowersucha niceflowerso many/ few flowerssuch nice flowerssomuch/little money.such a lot of peoplesuch rapid progressso many peopleso many已成固定搭配，a lot of虽相当于many,但a lot of为名词性的，只能用such搭配。换。sothat与suchthat之间的转换既为so与such之间的转E g : The MP3 cost memoney that I ccouldnafford to buy it .A . so much . B
15、 . such much C .so many D . such many . (Key : A )to.,so that.such. that .enough的互换.so that to = in orderto /that的用法.Eg A . He is too young to go to school.B . He is a young boy he go to school .C .He is young he go to school .D . He isnt go to school (Keys : B : such , that ,can t C : so , that , c
16、an t . D : old , enough to )易错分析：关于 notuntil He stayed there until it was very late. 句中，stay是可持续性动词，所以不用noteHe didn t leave until it was very late. 句中， leave 是不行持续性动词，所以用not because, so； although, but 上面已经提到，because和so及although和but不连用。例如： Because he was late, he didn t catch the first bus.确定不彳亍以说 Be
17、cause he was late, so he didn t catchthe first bus.or还是and 祈使句+ or +陈述句前后是对立的祈使句+ and +陈述句前后是统一的 (or或and后的陈述句，常用一 般将来时)Study hard, or you won t pass the exam. Studyhard, and you will pass the exam. 两句都可以转换成If条件句 +主句形式，留意：要去掉or和and：If you don t study hard, you won t pass the exam. If you study hard,
18、you will pass the exam. because, since, as, for表示缘由时的区分 尽管because, for, since, as都表示缘 由，但是用法上有不同.because通常表示说话人认为这种理由或者缘由是听话人所不知道的.如： He didn t attend the meetingbecause he had too much work to do. since 表示的缘由是人们已 知的事实，常译作既然。如：Since he can t answer this question, you d better ask someone else. as表示缘
19、由与since差别不大，只是语气更弱，多 译为由于如：As I haven t seen the film, I can t tell you what I think of it. for表示因果关系时，只能放在主句之后，不能放在句首。而且常常是对主句补充说明理由或推断缘由。如：It rained last night, for the ground is wet. as, when, while这三个连词都可引导时间状语从句，但用法有所不同。1）当某事正在进行的时候，又发生了另一件事。While, when, as都可用来引导表示背景的时间状语从句。例如：As/When/While I w
