    中考语法专题六 连词 介词 第二部分 语法复习 考点一、并列连词:表示词、短语、从句或句子彼此之间具有并列关系。 (一)并列句的意义 英语中由两个或两个以上的独立分句组成的句子叫“并列句”,这些独立分句在句中处于平等的、互补依从的地位。英语并列句不能只用逗号将分句或分句隔开,而应该用分号或并列连词将分句隔开。英语中并列连词主要有:and, but, yet, or, so, for, while, neither…nor…,either…or…,not only…but also…等。 连词是一种虚词,在句中不能单独作句子成分,它只是起连接词与词、短语与短语、句子与句子的作用。连词主要分为并列连词和从属连词两大类。 ※ 连 词 ※ 考点一、并列连词:表示词、短语、从句或句子彼此之间具有并列关系。 (二)表示“添加”关系的并列连词 1.and连接并列分句,表示意义的引申,分句间有着平行、因果、顺接、评论、对比或条件等关系。例: He is a teacher and his wife is a doctor. (平行) Peter heard someone crying for help and he ran out.(因果) He went into the restaurant and found a table by the window.(顺接) He missed the opening ceremony, and that’s a pity.(评论) Tom likes singing and Jane likes dancing.(对比) Work hard and you’ll make it.(条件) = If you work hard, you will make it. 考点一、并列连词:表示词、短语、从句或句子彼此之间具有并列关系。 2.在否定句中列举并列成分不用and,而用or。例: We can’t eat or drink in the computer room. There is no air or water on the moon. = There is no air and no water on the moon. 3.both…and…(既……,又……),not only…but also…(不仅……,而且……),连接两个名词或代词,也可连接谓语动词。both…and…连接名词或代词作主语时,谓语动词用复数形式;not only…but also…连接两个主语时,谓语动词要与最靠近的主语在人称和数上保持一致(就近一致),also有时可以省略。例: 考点一、并列连词:表示词、短语、从句或句子彼此之间具有并列关系。 Bill is both a good cook and a good dancer. Both Peter and Tom are students. Not only you but (also) he is a top student. = Not only he but (also) you are a top student. (三)表示“选择”关系的并列连词 or (或者),neither…nor…(既不……也不……), either…or…(或者……或者……/不是……就是……)等,在两个并列名词或代词作主语时,谓语动词要与最靠近的主语在人称和数上保持一致(就近一致)。例: You may go or stay. 考点一、并列连词:表示词、短语、从句或句子彼此之间具有并列关系。 Neither he nor I am going there. = Neither I nor he is going there. Either you or I am crazy. = Either I or you are crazy. (四)表示“转折”和“对比”关系的并列连词 or(否则),but(但是),yet(但是,然而),while(而…)。but一般表示转折,指和上一分句的情况相反;yet表示转折,语气比but强烈;while表示对比,语气并不很强。例: I must go now, or I will miss the last train. 考点一、并列连词:表示词、短语、从句或句子彼此之间具有并列关系。 I would like to go with you, but I can’t. He was not very rich, yet he was very happy. He likes dancing while I like singing. (五)表示“因果”关系的并列连词 for (因为,由于)表示补充说明理由,一般不用于句首;so(所以)表示结果。 例:She felt no fear, for she is a brave girl. I am tired, so I stayed at home. 考点自测 从and,but,or,while,for,so中选择适当的词填空。 1.The dress fits me well,________ I don’t want to buy it because it’s too expensive. 2.When you are learning English, use it,__________ you will lose it. 3.It was snowing hard _________ we had to stay at home. 4.He is short ________ his brother is tall. 5.The shop is quite new, _________ it has been open for a week. 6.He likes English _________ he is good at it. but or so while for and 考点二、从属连词:用来引导从句,与主句一起构成主从复合句。 (一)从属连词用于状语从句中。 when / while当……时候(引导时间状语从句) since自从…. 以来after 在…之后; before在…之前 ; as soon as 一…就…; until 直到(引导时间状语从句) if 如果, unless 除非(引导条件状语从句) if 是否(引导宾语从句) because 因为since 既然(引导原因状语从句) in order that ; so that 以便,以致(引导目的状语从句) so… that …;such… that 如此……以至于…… (引导结果状语从句) 考点二、从属连词:用来引导从句,与主句一起构成主从复合句。 though ; although 虽然 (引导让步状语从句) as… as … 像……一样(引导比较状语从句) (二)注意事项 1. until 在肯定句中的谓语动词必须为延续性动词, 意为“一直到… 结束”;在否定句中谓语动词必须为终止性动词,意为“直到… 才开始”。 例:He waited until his mother came back. He did not leave until his mother came back. 考点二、从属连词:用来引导从句,与主句一起构成主从复合句。 2. if (如果) unless ( 除非) as soon as , when ( 当….时候) 等引导从句时候,主句是将来时 / 含有情态动词 / 祈使句,从句用一般现在时代替将来时。 例: I will go if it doesn’t rain tomorrow. Call me when he comes back. You shouldn’t speak loudly in class unless you raises your hand. 3. when 和while 都有“当…时候”, 但while 引导的时间状语从句中的谓语动词必须用表示状态的延续性动词,而when 不受此影响。 考点二、从属连词:用来引导从句,与主句一起构成主从复合句。 Please buy me some stamps while you are in the post office. 4. as… as …. 像….一样(引导比较状语从句),结构中要用形容词或副词的原级。例:He can run as fast as his brother. 5. although / though 和but ; because 和so 不能出现在同一句( although和 yet 可以) 例:Though it is raining, they are still working in the field. Because he got up late, he was late for school. 考点二、从属连词:用来引导从句,与主句一起构成主从复合句。 6. 结果状语从句so…that… 与 such… that …. 注意主从句时态一致 adj. ★so adv. that many / few 可数名词复数 much / little 不可数名词 ★so adj. a / an n. (单) that ※such   a / an adj. n.(单) that ※such adj. n.
