專題八 初中英語連詞講解及練習

并列連詞

2)either?or 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.3)or, or else/ otherwise 否則

Be silent, or else you will be kicked out.I am tired, otherwise, I would play.(6)prefer to…rather than…與prefer…to…的區別：prefer to…rather than…后面都是用動詞原形,prefer…to…都是用動名詞或名詞。如：I prefer English to Japanese.（與日語相比我更喜歡英語）/ I prefer to learn English rather than learn Japanese.（與日語相比我更喜歡學英語）

第三類表示轉折或對比關系的連詞

1）but 但是He is rich but unhappy.while 然而，表示對比意味Some people love cats, while others hate them.yet 然而She said she would be late, yet she arrived on time.however 然而，可是，不過She does not like him, however, I like him.2)not?but? 意思為“不是 ??而是??”

not 和but 后面的用詞要遵循一致原則。

---I'd like to, ___ I'm too busy.A.andB.soC.asD.but

第四類表因果關系的連詞

1)for 因為，做并列連詞用時，是在對先行的句子補述原因或者理由，只可以連接句子與句子，通常不置于句

首。

He hurt his leg, so he couldn't play in the game.I think, therefore I am

3）then 那么，因而

Hide behind the wall, then they won’t see you.注意：

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.從屬連詞

從屬連詞只能用來引導從句，而不能引導詞或者詞組。從屬連詞一般可以引導名詞性從句和狀語從句。

第一類引導名詞性從句的從屬連詞

1）that 引導賓語從句或間接引語時，可省略。引導主語從句時不可以省略。

He said(that)he would come.賓語從句

His mother told me(that)he is a good boy.間接引語

That she is still alive is true.主語從句

2）if/whether 是否

I wonder if he is at home.I ask him whether he would come.注意：只可以用whether的情況

1.介詞后面It will depend on whether it rains tomorrow.2.whether···or not 固定搭配Let me know whether you come or not.3.動詞不定式前I don’t know whether to accept his advice.第二類引導狀語從句的從屬連詞

1）連接時間狀語從句的從屬連詞

詞是延續性的動詞）

as 當···I saw her as I was getting on the bus.till/until 直到I didn’t go to sleep until/till I finished my homework.as soon as 一···就··· As soon as he saw the policeman, the thief run away.2）連接地點狀語從句的從屬連詞

where 在哪里There were lots of parks where I lived.3）連接原因狀語從句的從屬連詞

because 原因,用于解釋某事的原因，動機，強調直接原因和因果關系I do it because I like it.for 表因為，表間接的原因，用于說明，解釋I soon went to sleep, for I was tired

since 表原因，比because弱，比as強，表一種已知的，顯然的理由，常譯為“既然as 表原因時，意義最弱 As you are in poor health, you should do more exercises

4）連接結果狀語從句的從屬連詞

so···that···如此···以至于···He is so kind that everybody likes him.such···that···He is such a kind man that everybody likes him

D.while 【答案解析】

1.D.考查“祈使句/名詞+and+陳述句”句型。句意為：“再努力點，你就會成功的”。2.B.so(因此)是并列連詞，引出一個表示結果的分句，前面應是一個表示原因的分句，而無需再用連詞，排除A；C和D又不是句子，也錯了。

3.D.因為rather than是對稱連詞，意為“而不”(from www.tmdps.cn)。

4.A.因為but是并列連詞，后面是個句子，前面也一定是個句子，而不是一個分詞短語或不定式短語，更不能再用連詞though，所以排除B、C和D。

5.C.考查“祈使句+and+陳述句”句型，意為“如果?就?”。雖然or也可用于此句型，但or是“否則、要不然”之意，如：Work hard, or you’ll fail.(努力學習，否則就會不及格。)6.D.因為not only?but(also)?是固定搭配(from www.tmdps.cn)。

7.D.因為句中的并列連詞for表示原因，是對前面分句所述內容的解釋或補充說明。8.A.因為句中的并列連詞while表示“對比或相反”。9.B.因為句中的并列連詞when = just at that time, 意為“這時(突然)”。10.D.因為只有or才能表示選擇，意為“(是?)還是”。

11.C。本題考查what引導主語從句，并在主語從句中作主語。句意為“在許多國家，所謂的“公立學校”并非公眾擁有。

12.B。本題考查引導主語從句的連接詞。that引導主語從句只起連接作用，在從句中不作任何成分，無意義，但不能省略。what除引導主語從句外, 還在從句中作成分。which指一定范圍內的“哪一個”；whether意為“是否”。根據句意“世上的事喜憂交替”可知答案為B(from www.tmdps.cn)。

13.D。該題考查賓語從句。可以看作是does it matter which book it was的省略。一定注意此題受母語干擾，很容易錯選答案為A。只要抓住題干前一句I read about this story in some book or other的提示，就可知道是指一定范圍內的“哪一個”，故答案為D。14.D。that引導同位語從句；what the book said是同位語從句中的主語。

15.A。本題考查以after引導的時間狀語從句，意為“在?之后”。句意為“步行了六小時后，我累壞了”。

16.C。even if=even though,引導的讓步狀語從句，意為“即使, 盡管”，符合題意。17.D。本題考查before引導的時間狀語從句，意為“在??之前”。句意為“他來不及沖進去救他的孩子，屋頂就塌了”。18.C。When it comes to...是一固定句型，意為“當談到??時，涉及”。句意為“做作業是提高考分的一個可靠方法，這在涉及到課堂測驗時尤其正確”(from www.tmdps.cn)。19.B。該題考查where引導的地點狀語從句，表示“在?地方”。句意為“我一直把照片放在我每天都能看到的地方，因為它總使我回想起大學里的日子”。20.B。so long as=so long as, 意為“只要”，表示條件。句意為“只要你答應歸還，你就可以把這書借走”。

21.D。本題考查as引導的時間狀語從句，表示事物的進展，意為“隨著”。句意為“那人年紀越來越大，除了園藝外其他都不感興趣”。22.A。once引導的讓步狀語從句，意為“一旦”。句意為“一旦明白了這條規則，就再也沒有困難了”。

23.B。no sooner?than意為“剛?就”，相當于as soon as.句意為“我剛走回廚房,門鈴又響了,響得足以把死人吵醒”。類似用法還有hardly / scarcely?when.。

24.A。本題考查because引導的原因狀語從句及與for的區別。for不能跟not...but這一結構連用，句意為“我批評他不是因為我恨他而是因為我愛他”。

25.C。unless引導的條件狀語從句。句意為“他如果不努力學習, 就永遠不能考及格”。26.B。so that引導目的狀語從句。句意為“她拼命干一邊能在他回來時把一切都準備好”。27.D。until引導的時間狀語從句。句意為“他一直等到火山平息下來,兩天后他才得以重回火山上”。28.C。此題很容易錯選B。誤認為是not?until句型。實際上只要抓住your work is being done.這一提示就找到了答題的關鍵。

29.D。本題考查until引導的時間狀語從句，意為“到...為止, 在...以前”。30.A。名詞短語the moment用作連詞，相當于as soon as,引導時間狀語從句。意為“一??就”。類似的短語或詞還有the minute, the instance, directly, immediately等

第三篇：初中英語并列連詞總結

并列連詞

連詞是一種虛詞，它不能獨立擔任句子成分而只起連接詞與詞、短語與短語或句子與句子作用。連詞主要分為兩類：并列連詞和從屬連詞。

并列連詞表示單詞、短語、從句或句子間有并列關系。分為：表平行或對等關系的連詞、表轉折關系的連詞、表選擇關系的連詞、表因關系的連詞

一、并列連詞：

1.and “和” ；both…and…“……和……兩個都” ；as well as“也”

not only…but also…“不但……而且……”;neither…nor…“既不……也不……” 例My mother bought me a present,and I like it very much.我媽媽買了一件禮物給我，我很喜歡He can speak not only English but also French.他會說英語還會說法語。

2.but“但是”；yet“然而”；while“而”；however“然而”

例： Lucy likes red while Lily likes white。露西喜歡紅的，然而莉莉喜歡白的。

3.or“或者”；either…or…“要么……要么……”

注：由or 連接的句子可以轉換為有否定條件構成的主從復合句。

Eg：Study hard，or you’ll fail the exam.=If you don’t study hard,you’ll fail the exam.努力學習，否則你考試會失敗的。

Either you or he goes.“要么你去，要么他去”。

4.表因果關系的并列連詞so “所以，因此”;for “因為”

Eg：Kate was ill so she didn’t go to school.凱特病了所以沒去學校。

I have to stay up，for I have lots of homework to do。我必須熬夜，因為我有很多作業。

二、不能同時出現在一個句子中的連詞。

1.because（因為),so（所以)不能同時出現在一個句子里，只能用其一.eg：Because he was tired,he couldn’t walk here.=He was tired,so he couldn’t walk there.因為他很累，所以走不到這里。

2.although/though（雖然），but（但是）不能同時出現在一個句子里，只能用其一。但although/though和 yet 可以同時出現在一個句子里（yet 用作副詞）

Eg:Though he was tired,he still worked hard.=He was tired,but he still worked hard.：雖然他很累，但是她仍然堅持工作

三、and 和or 用于否定句中的區別

1)當列舉成分是主語，又在否定詞之前時用and連接；而當列舉成分在否定詞之后時，用“or”構成完全否定.Eg：I can’t sing or dance.我不會唱歌，也不會跳舞。

Lucy and lily can’t speak Chinese.露西和莉莉都不會說漢語。

在否定句中，如果所連接的兩部分都有否定詞那么用“and”而不用“or”

Eg：There is no water and no air on the moon.月球上沒有水也沒有空氣。

2)在否定句中，without +and；而在肯定句中，without+or,構成完全否定。

Eg：Man can’t live without air and water=Man will die without air or water.五、由 either……or….., neither……nor……,not only……but also……連接兩個并列主語時，謂語動詞與較近的主語保持一致。（就近原則）

Not only my parents but also I am looking forward to meeting you.不止我父母，連我很也很想見到你。
