小升初英语语法 连词

九、连接词

1、连词的含义：连接词与词、短语与短语、或引导从句的词叫连接词，它是虚词，所以不能单独担任句子成分。。

2、连词的分类：连词分为并列连接词和从属连接词两种。

1)并列连接词连接并列的词、短语、从句或句子。常见的并列连接词有：and(和), but(但是), or(或

者,否则), nor(也不), so(所以), however(然而,无论如何), for(因为), still(可是), as well as(也),

both..and...(...和...), not only ...but also...(不但…而且…), either… or…(或…或…), neither… nor…

(既不…也不…) 等。

2)从属连接词用于引导从句, 常见的从属连接词有：when(当…时候), while(正当…时候),

after(在…之后), before(在…之前), since(自从), until(直到), although/though(虽然), if(假如),

as(如…一样；由于), as …as…(和…一样), as far as(就…而言), as long as(只要), as soon as(一…

就…), even if(即使), because(因为), unless (除非), than(比…), whether (是否…), in order

that…(为了), so…that…(如此…以致), so that…(以便), now that…(现在既然), by the time…(到…

时候), every time…(每当), as if…(仿佛),no matter when(或whenever)(无论何时),no matter

where(或wherever)(无论在哪里)等。

3、常用并列连词用法

1) “and”

1. He got up and left the room.

2. He went to Kunming and I went to Harbin last year.

特别用法: 句型“祈使句, and …”= If you…, you will…

3. Work hard, and you will do well in the exam.

2)“or”

1. Tom or I am right. (or连接两个名词或代词做主语时谓语动词依照后面的词而定)

2. Would you like coffee or tea? （选择）

特别用法: 句型“祈使句, or…”= If you don’t …, you will…

3. Hurry up, or you will miss the bus. （否则）

3)“but”

1. She is sixty, but she still looks young.

2. She is tired but happy.

3. I came here not for myself but for my son.

4. Mary likes piano but Tom doesn’t (like可以省略).

4)“for”

1. I went to sleep soon, for I was very tired.

2. The sun has risen，for the birds are singing.

比较：表示原因, 译为”因为”, 表示说明、解释。与because不同，用于解释某事的原因、动机，强调因果关系。用语回答why引导的问句。

5)“both …and …”

1. Both you and I are Chinese.

2. I like both sports and music.

特别用法: both…and…的否定句表示部分否定。

3. He can’t play both tennis and volleyball. 它并不是既会打网球又会打排球。

6) either…or…, neither…nor…

1. Either you or she is wrong.

2. Can you speak either French or English?

3. Neither the teacher nor the students like this song.

特别提示: 用either…or…, neither…nor…连接两个名词或代词做主语时谓语动词依照后面的词而定

比较: both…and…, either…or…, neither…nor…的相互关系:

肯定句: 1. I like both A and B.

否定句: 2. I don’t like both A and B.= I like either A or B.

否定句: 3. I don’t like either A or B.= I like neither A nor B.

7)“Not only…but also…”

1. Not only you but also your father is coming.

(连接两个名词或代词做主语时谓语动词依照后面的词而定)

2. She learns not only English but also Japanese.

4、连词的辨析

1)because、as、since、for的用法：because(因为)表示原因的语气最强, 常表示必然的因果关系,

从句一般放在主句后面；另外, 回答why的问句只能用because. as(因为)表示一般的因果关系,语气比because弱, 说明比较明显的原因, 它引导的从句可以放在句首也可以放在句尾。Since (既然)表示对方已经知道、无需加以说明的原因或事实。for(因为)是并列连词,语气较弱, 用来补充说明理由或提供一种解释。如：

He is not at school today because he is seriously ill.（他今天没有上学因为他病得厉害）

As all of you have got here, now, let’s go to the zoo.（既然大伙儿都到了我们就去动物园吧）
