2018年英语中考归纳复习专题:连词与从句
【连词】
用来连接词与词、短语与短语,以及句子与句子的词叫连词。连词属于虚词,在句中不能单独使用。连词按其性质可分为两类:并列连词和从属连词。从属连词主要用来引导宾语从句和状语从句。
1.并列连词
并列连词是指用来连接并列的单词、短语、从句或句子的连词(如and,but,or,so等),可表示并列、顺承、转折、选择、因果等关系。常见并列连词(短语)用法如下:
关系 |
连词(短语) |
意义 |
例句 |
说明 |
||||||||
并列 关系 |
and |
和;又 |
She is kind and patient.她既友好又有耐心。 |
表并列,and前后的词意义相近,否定句中用or。 |
|
|||||||
然后 |
He came in and took off his coat.他进来然后脱掉外套。 |
表示动作先后。 |
|
|||||||||
那么 |
Be careful,and you will make fewer mistakes.细心点,你就会少犯错误。 |
祈使句+and+陈述句(表结果)。 |
|
|||||||||
both... and... |
两者都 |
Both Linda and Amy like reading.琳达和埃米都喜欢阅读。 |
连接并列主语时,谓语动词用复数形式。 |
|
||||||||
并列关系 |
neither... nor... |
既不…… 也不…… |
Mr.Gao neither drinks nor smokes.高先生既不喝酒也不抽烟。 |
连接并列主语时,谓语动词的形式遵循“就近原则”。 |
||||||||
not only... but also... |
不但…… 而且…… |
Not only he but also I am excited about the news.不但他而且我也对这个消息感到兴奋。 |

但是 |
The man is poor,but he is happy.这个人很穷,但他很快乐。 |
不能与(al)though同时使用。 |
||||||||
while |
然而
|
I like red while she likes blue.我喜欢红色而她喜欢蓝色。 |
强调对比关系。 |
|||||||||
选择 关系 |

Who is taller,Sam or John?谁更高,萨姆还是约翰? |
表示选择。 |
|
|||||||
否则; 要不然 |

祈使句+or+陈述句(表结果)。 |
|
|||||||||

2.从属连词从属连词主要用来引导宾语从句(if,whether)和状语从句(如when,because,until等)。
常见从属连词用法见以下考点2宾语从句和考点3状语从句的讲解。【考点训练1】

【宾语从句】
在复合句中充当宾语的从句叫宾语从句。其结构是:主句+引导词+从句。
学习时要掌握宾语从句的三要素:引导词、语序、时态
1.引导词
引导词 |
作用 |
例句 |
that |
本身无意义,只起连接作用,口语中可省略。 |
He said (that) Kate was good at swimming.他说凯特擅长游泳。 |
if/whether |
意为“是否”,不作句子成分,但不能省略。 |
He asked me if Miss Gao was a teacher.他问我高小姐是否是一位老师。 |
what,which,who,whose, whom |
连接代词,在从句中充当一定的成分(作主语、宾语、定语等)。 |
I don’t know what they are going to do.我不知道他们将要做什么。 |
when,where,why,how |
连接副词,在从句中通常作状语。 |
Could you tell me where you are going?你能告诉我你要去哪儿吗? |
2.语序
宾语从句要用陈述句语序:主语+谓语+其他。如:
Do you know where the nearest hotel is?
你知道最近的旅馆在哪里吗?
时态
时态规律 |
例句 |
主句为一般现在时时,宾语从句的时态不受主句时态的限制,根据实际情况使用相应的时态。 |
I remember he gave me a book yesterday.我记得他昨天给了我一本书。 |
主句为(一般)过去时时,宾语从句只能使用过去的某种时态。 |
Kate asked what Tom was doing then.凯特问汤姆那时正在做什么。 |
从句表示的是客观事实、真理等时,宾语从句的时态不受主句时态的限制,用一般现在时。 |
Mr.Gao told us that light travels faster than sound.高老师告诉我们光比声音传播得快。 |
注意:在以Could you 开头的复合句中,could通常不表示过去时态,仅表示委婉语气,从句的时态要根据实际情况而定。如:
Could you tell me where Helen lives?你能告诉我海伦住在哪里吗?
Could you tell me where you went last weekend?你能告诉我上周末你去了哪里吗?
要点提醒:
宾语从句的简化
当主句的谓语动词是tell,ask,show,teach等,且后带双宾语,从句主语和间接宾语一致时,宾语从句可简化为“疑问词+不定式”结构。此结构中的疑问词包括what,which,how,when,where等。如:Could you tell me how I can get to the station?→Could you tell me how to get to the station?

状语从句

|
要点提醒:
1.在含有时间状语从句和条件状语从句的复合句中,如果主句是一般将来时,从句要用一般现在时表示将来。如:
I’ll ring you up as soon as I get to Beijing.我一到北京就给你打电话。

【定语从句】
在复合句中作定语,修饰主句中某一名词或代词或修饰整个句子的从句叫定语从句。含定语从句的复合句的基本结构为:先行词+关系词+定语从句。被定语从句所修饰的词叫先行词,通常位于定语从句之前。定语从句须用关系代词(who,whom,whose,which,that)和关系副词(when,where,why)来引导,它们位于先行词和定语从句之间。关系词常有三个作用:
①引导定语从句;
②代替先行词;
③在定语从句中充当一个句子成分。其用法如下:
1.关系代词的基本用法
