备战2023英语新中考二轮复习考点精讲精练（广东专用）突破 05 连词

一、考点总结

并列连词and, but, or, so等的主要用法；常用从属连词的基本用法。

考点一、 并列连词的用法

并列连词是用来连接语法地位相同的单词、短语以及句子的连词。并列连词主要分为表示并列关系、转折关系、因果关系及选择关系的并列连词。

【注意】

1.“祈使句+or+结果句” = “If you don’t…,you’ll…”，其中or意为“否则”

例：Hurry up, or you will be late. 快点，否则你就会迟到了!

=If you hurry up, you won’t be late. 如果快点，你就不会迟到了。

=If you don’t hurry up, you will be late. 如果不快点，你就会迟到了。

2. but “但是”，用来表示转折关系，注意它不能与though,although连用
3. so “所以，因此”用来表示因果关系，注意它不能与because,since,as连用
4. for “因为”，表示原因，主要用来进行补充说明，没有因果关系
5. not only…but also,neither…nor…和either…or…连接两个主语时，谓语动词与最近的主语保持一致；both…and…连接两个主语时，谓语动词要用复数形式；而as well as连接两个主语时，谓语动词同前面的主语在人称和数上要保持一致

例：Not only I but also my mother is going to the museum. 不仅我而且我的母亲也要去博物馆。

Neither you nor I am right. 你和我都不对。

Either you or he is right. 要么你对，要么他对。

Both Li Ping and her father take exercise every morning.李萍和她的父亲每天早晨都进行锻炼。

考点二、 从属连词

1.引导状语从句的连词

（1）引导时间状语从句的连词：when, while, as, before, after, until, till, as soon as, since等。时间状语从句和主句的时态关系为：主将从现，主过从过。

① when 意为“当……时”。如：I was doing my homework when the telephone rang. 电话铃响的时候，我正在做作业。

② while 意为“正当……时，正在……时”。在while引导的从句中，谓语动词必须是延续性动词，且常常用进行时；as 意为“正当……时”， as引导的从句中，谓语动词既可用延续性动词，也可用短暂性动词。如：

He fell asleep while/as he was watching TV. 他看着电视睡着了。

As Millie sat down on the sofa, Amy came into the room. 米莉坐在沙发上时，艾米走进了房间。

③ before 意为“在……之前”；after 意为“在……之后”。如：

I’ll wait for you here before you come back. 在你回来前，我会在这儿等你。

④ until 意为“直到……为止”。如：

The child didn’t go to bed until his mother came back. 直到他妈妈回来了，这孩子才去睡觉。

⑤ as soon as 意为“一……就……”。如：I’ll call you as soon as I get there. 我一到那儿就会给你打电话。

⑥ since 意为“自从”。如：I have lived in Beijing since I came to China. 自从来到中国以来，我就住在北京。

（2）引导条件状语从句的连词有：if, unless等。如：We’ll be late unless we hurry up. 除非快点儿，否则我们会迟到。

If it is fine tomorrow, we’ll go to the park. 如果明天天气好，我们就去公园。

（3）引导目的状语从句的连词有：so that(是为了；以便于)；in order that(以便于)等。如：

He got up early so that/in order that he could catch the early bus. 他起得很早是为了能赶上早班车。

I spoke loudly in order that everyone in the room could hear me. 我大声说话是为了让屋里的每个人都能听得见。

（4）引导原因状语从句的连词有：because, as, since等。如：She didn’t go to work because she was ill.

【注意】because与so不能同时出现在一个句子中。

（5）引导结果状语从句的连词有：so…that，such…that等。so…that和 such…that 意思均为“如此……以至于……”，so后接形容词或副词，such后接名词或名词性短语，that后接从句。如：

I was so tired that I couldn’t go any further. 我累得走不动了。

Tom is such a clever boy that/so clever a boy that everyone likes him. 汤姆是如此聪明的一个男孩，大家都很喜欢他。

（6）引导让步状语从句的连词有：though, although, even if(＝even though)等。如：

The dress looks nice on you though/although it’s out of style. 虽然这件连衣裙过时了，但穿在你身上还是很漂亮。

【注意】though和although不与but连用。

（7）引导比较状语从句的连词有：than, as…as…等。如：He is better at English than I. 他的英语比我好。

I think English is as important as math. 我认为英语和数学同等重要。

2.引导宾语从句的连词

that(陈述句作宾语，从句由that引导，that无意义，可省略)，if/whether(一般疑问句作宾语从句用if或whether引导，意为“是否”)和特殊疑问词(用来引导特殊疑问句所作的宾语从句)。如：

I want to know when you will start. // I’m worried about whether she can come here on time.

常用连词用法区别

1.while, when, as的用法区别：

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。如：

As/When/While I was walking down the street, I noticed a police car.

（2）当两个长动作同时进行的时候，最常用的是while。如：

While mother was cooking lunch, I was doing my homework.

（3）当两个动作都表示发展变化的情况时，最常用的是as。如：

As children get older, they become more and more interested in things around them.

（4）当两个短动作同时发生时，或表示“一边……一边……”时，最常用as。如：

Just as he caught the fly, he gave a loud cry. // She looked behind from time to time as she went

（5）当从句的动作先于主句的动作时，通常用when。如：When he finished his work, he took a short rest.

（6）当从句是瞬间动作，主句是延续性动作时，通常用when。如：When John arrived I was cooking lunch.

2. as, because, since, for的用法区别：

这四个词都可表原因，但用法有区别。

（1）如果原因构成句子的最主要部分，一般用because。因此，because引导的从句往往放在句末。例如：

I stayed at home because it rained.  //  ---- Why aren’t you going?   ---- Because I don’t want to.

（2）如果原因已被人们所知，或不如句子的其它部分重要，就用as或since。since比as稍微正式一点as和since 引导的从句一般放在句子的开头。如：

As he wasn’t ready, we left without him.  //  Since I have no money, I can’t buy any food.

（3）for用来补充说明一种理由，因此，for引导的从句几乎可以放在括号里。For引导的句子不放在句子的开头。如：

I decided to stop and have lunch----for I was feeling quite hungry.

3.if, whether的用法区别：if和whether都可作“是否”讲，在引导宾语从句一般可互换。如：

I wonder whether (if) you still study in that school.  //  I don’t know whether (if) he likes that film.

在下列情况下，只能用whether，不能用if：

（1）引导主语从句时。如：Whether he will come to the party is unknown.

（2）引导表语从句时。如：The question is whether I can pass the exam.

（3）引导宾语从句时，①在不定式前；②在具有选择意义又有or或or not时，尤其是直接与or not连用时，往往用whether，而不用if；③宾语是介词引导的从句时用whether；④有时为了强调，将宾语从句放在句首时用whether。如：I haven’t made up my mind whether to go there or not.

They are talking about whether to go there or not. // Can you tell me whether or not he will come to our party.

It depends on whether it is going to rain. // Whether the story is true or not, I don’t know yet.

4.so…that, such...that的用法区别：

（1）so…that中的so是个副词，其后只能跟形容词或副词，而such...that中的such是个形容词，后接名词或名词短语。如：I’m so tired that I can’t walk any farther. // It was such a warm day that he went swimming.

（2）如果在名词之前有many, much, little, few时，用so，不用such。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.although, but的用法区别：

这两个连词不能用在同一个句子中。例如：我们不能说“Although he is over sixty, but he works as hard as others.” 这个句子应改为：Although he is over sixty, he works as hard as others.或He is over sixty, but he works as hard as others.

6.because, so的用法区别：

这两个连词同样不能用在同一个句子中。例如：我们不能说“Because John was ill, so I took him to the doctor.” 这个句子应改为Because John was ill, I took him to the doctor.或John was ill, so I took him to the doctor.

7.and和or的用法区别：

（1）and用于肯定句中，or用于否定句或选择疑问句中。如：

I like bread and milk for breakfast. 我早餐喜欢吃面包，喝牛奶。

I don’t like bread or milk for breakfast. 我早餐不喜欢吃面包，喝牛奶。

Would you like some tea or coffee? 你喜欢喝茶还是咖啡？

（2）否定句中两部分都有否定词时用and连接。如：

Bill has no brothers and no sisters.=Bill has no brothers or sisters. 比尔没有兄弟姐妹。

（3）句中含有without时，肯定句中用or，否定句中用and。如：

We can’t live without air and water. 没有空气和水，我们无法生存。

We’ll die without air or water. 没有空气和水，我们就会死亡。

（4）and与or(表示“否则”)都可以与if引导的条件状语从句转换。如：

Get up quickly, or you’ll be late for school.=If you don’t get up quickly, you’ll be late for school.

Work hard, and you’ll get good grades.=If you work hard, you’ll get good grades. 努力学习，你会取得好成绩。
