连词的作用:把词与词、短语与短语、句子与句子连接起来。它不能在句中单独作句子成分。
二、连词分类:并列连词从属连词—

that,whether, if, unless, while / when, until, because, s that, s…that, thugh/ althugh, even if, as…as 等
连词按其性质可分为:从属连词并列连词
(1)表示联合关系,联合的双方是对等的,意义上趋向一致。常用连词有:and “和” “两者都” “既不…也不…”nt nl a ls “不但…而且…”as well as “也”as... ... as “和... 一样”
Eg:我喜欢苹果和香蕉。I like apples and bananas.I like bth apples and bananas.I like nt nly apples but als bananas.我不喜欢苹果和香蕉。I like neither apples nr bananas.
Eg:你和Tm都是我的好朋友。Yu and Tm are my gd friends.Bth yu and Tm are my gd friends.Nt nly yu but als Tm is my gd friend.你和Tm都不是我的好朋友。Neither yu nr Tm is my gd friend.
那些学生和她都喜欢音乐。The students as well as she music.
(2)表示转折关系,连接的双方构成对比,意义上有转折。常用连词有but、hwever、yet、whileeg:Yu can watch TV, but yu must finish yur hmewrk first.
was watching TV.
while在表示转折关系时,往往连接内容和结构对称的两个部分,用来表示鲜明的对比。
I lve strng tea whlie my father lves cffee.My mum was cking while my father _______(watch TV).
yet连接句子时,表示惊讶或者转折,译为“但是,然而”
She said she wuld be late, yet she arrived n time.Mike was usually s careful, yet this time he made a small mistake.
(3)表示选择关系的连词,连接的双方只取其一。常用连词有r “或者” “或者…或者”nt... “不是 ...而是”
eg:你今天或明天可以去北京。Yu can g t Beijing either tday r tmrrw. Yu can g t Beijing tday r tmrrw. 你必须早点起床,否则你就会迟到。 Yu must get up early r yu will be late.
Eg:或者你或者他是中国人。Either yu r he is Chinese.或者他或者你是中国人。Either he r yu are Chinese.
1._______Lily_____Lucy can g with yu,because ne f them shuld stay at can g with yu, because they shuld d their hmewrk tnight. 3.______Lily______Lucy can g with yu, ______they shuld finish their hmewrk at first.
(4)表示因果关系,连接的双方,互为因果,或者前因后果,或者前果后因。常用的连词有: fr “因为” s “所以”because“因为”
+最直接的原因(句子)
Eg:一定已经下过雨了,因为地面是湿的。It must have rained, fr the grund is wet.刚才下雨了,所以地面湿了。It rained just nw,s the grund is wet.
例1:Cme tmrrw, I will give it t yu.A.r B.and C.thughD.if提示:and在此处解释为“那么”,表示递进关系。
例5:The teacher his students likes ftball.A.and B.as well as C.and alsD.als提示:as well as 连接两个主语用靠前原则。
考点一: 1)判断改错: They sat dwn and talk abut smething. They started t dance and sang. I saw tw men sitting behind and ate there.
and (“和,并且”) 与 r (“否则”)
“and” 连接平行结构。
= Study hard, _____ yur math will be wrse.
2)用 “and” 或“r” 填空: Study hard, _____ yur math will be better.
祈使句+and+简单句 If+从句(肯定)“and”意为“这样,那么”; 祈使句+r+简单句 If+从句(否定)“r” 意为 “否则” 。
If yu wrk hard,yur math will be better.If yu dn‘t wrk hard,yur math will be wrse.
(1)肯定句中用“and” 表“和”;(2)否定句中用“r”表“和” 。
3)翻译:① 我喜欢英语和数学。 ② 我不喜欢英语和数学。
I like English _____ math.
I dn’t like English ____ math.
表转折的连词but 和hwever: e.g. (他努力工作,但以失败告终。) He wrked hard, ______ he failed at last. He wrked hard. _________, he failed at last.区别: but 后没有逗号,直接连接分句; hwever 后有逗号相隔,可放句末。
观察句子 : (1)Althugh he is ver sixty, but he wrks as hard as thers.改为:Althugh he is ver sixty, he wrks as hard as thers.或 He is ver sixty, but he wrks as hard as thers.(2)“Because Jhn was ill, s I tk him t the dctr.”
*althugh/ thugh 和but这两个关联词不能同时用。
同样,此句错误, because 和 s 等关联词都不能同时使用。
either A r B “或者A或者B”neither A nr B “既不A也不B”nt nly A but als B “不仅A而且B”
--- 连词词组 :
①Either yu r I _____ ging t the party.(或者你或者我将去晚会。)②Neither I nr he ______ seen the mvie.(我和他都没有看过这部电影。)③Nt nly yu but als he ________ French.(不但你而且他也讲法语。)
【连接主语时“就近原则”】

While Mr. White was taking a shwer,the UFO landed n the street.
“when” 和 “while”
when引导的状语从句的动作多为终止性动词,也为可持续动词;但while只能是可持续动词。
