1、 语法专项六—连词 一、连词的定义:连词是连接字、短语、从句与句子的词,是虚词,因此它不能独立担任句子成分。 二、连词的分类:连词主要分为两大类——并列连词和从属连词。 三、并列连词:并列连词用来连接并列关系的词、词组或分句。 它包括:and,or,but,so,for,both…and,either…or,neither…nor,not only…but also, as well as. (1)表并列关系的and, both…and, not only…but also, neither…nor, as well as (2)表选择关系的or, either…or
2、 (3)表转折关系的but (4)表因果关系的for, so 1、 and:和,并且 (1)表示“和”、“而且”的意思,用来连接对等关系的字和字,短语与短语,句子与句子。 Eg: He got up and put on his hat. Eg: I went to the Summer Palace and he went to Bei Hai Park. (2)单词或词组如果是三个以上连接,一般在最后的单词或词组前加and。另外“and”在译成中文时不一定要翻译出“和” Eg: Mary visited Beijing , Shanghai
3、 and Hong Kong. (3)and用于祈使句中,句型:祈使句,and…=If you…, you'll… Eg: Use your head,and you'll find a way.=If you use your head,you'll find a way. Eg: Hurry up,and you'll catch the bus.=If you hurry up,you'll catch the bus. 2、or:或,或者,否则 (1)or表示“或”的意思,用于两者之中选择一个。 Eg: Would you like coffee or tea
4、 (2)注意“A or B”作主语时,谓语动词随or后面的词(B)而定。 Eg: Tom or I am right. Eg: Li Ming or his classmates are cleaning the room. (3)用于祈使句中,句型:祈使句, or…=If you don't…, you'll…译成“请…,否则…”, 有转折的意思。 Eg: Hurry up,or you'll miss the bus.=If you don't hurry up,you'll miss the bus. Eg: Study hard,or yo
5、u'll fail in the exam.=If you don't study hard,you'll fail in the exam. 3、but:但是,可是,而 (1)但是,而,可是。表示转折关系。 Eg: He is old,but he looks very young. (but 后面省略了主语Li Li,因为与前面的主语成分相同) Eg: Mary likes violin, but Tom doesn't. (doesn't后面省略了like violin,因为与前面的成分相同) (2)在英文中,but和although不能在一起使用。
6、 Eg: Although it was raining hard , but they went on working. (错) Eg: It was raining hard ,but they went on working.(对) Eg: Although it was raining hard, they went on working.(对) 4、 so, for (1)so:所以,因此,于是 Eg: My teacher asked me to go,so I went. (2)so除了作连词外,也可以作副词。 Eg:

9、ister or my mother comes. 2)either···or的否定句是全否定。 Eg: Either you or he isn't right. 你和他都不对 Eg: I don't want to visit either Tianjing or Shanghai.天津和上海我都不想参观。 (2)neither…nor:既不……也不…… 1)构成的词组做主语时,谓语动词的用法和either…or的用法一样,由nor后面的词而定。 (就近原则) Eg: Neither you nor I am right. Eg: Neither you nor
10、 he was selected for the job. 2)neither···nor 是全否定,因此不能再用否定式,即不能再加not。 Eg:(×)Neither You nor I am not right. 7、not only… but also:不但……而且 not only…but also构成的词组担任主语时,谓语动词随 but also后面的部分而定。(就近原则) Eg: Not only you but also your father is coming. Eg: Not only the teacher but also the students
11、were against the plan. 8、as well as : 又、不但···而且 (1)as well as 构成的词组担任主语时,谓语动词随前面的词而定。(就远原则) eg: Jim as well as his parents joins in the party. (2)该句型可以和“not only…but also”互换,not only A …but also B = B as well as A ,前者强调的是B, 在not only之后,后者强调的也是B,在as well as之前。翻译时,要先翻译as well as 后面的词。 Eg
12、 The child is not only healthy but also lively = The child is lively as well as healthy. 这孩子既健康又活泼。 四、从属连词:从属连词用来引导从句,它包括: that, when,while , as, till, until, after, before, since,because,if, though,although,so…that,as soon as 常见的从属连词有: 1、 that: (1)that引导名词性从句(主语从句、表语从句、宾语从句和同位语从句)和定语从句,
13、 Eg: I think(that) he likes football. (2)如果主句的动词是 think, believe…;如果主句的主语是第一人称,变为否定句时,要否定主句,译成中文时,则否定从句。(否定前移) Eg: I believe you will leave here. Eg: I don't believe you will leave here. 2、 when,while,before, after , as soon as ,till, until , since… when, while, till, until, si
14、nce, after, before, as soon as等是连接时间状语从句的连词。当主句是将来时,从句要用一般现在时。 (1)注意while所引导的从句的谓语动词只能是延续性的,不能用点动词。(如begin,stop…) Eg: While I read, she sang. Eg: I entered the room while(when) Li Ming was talking with her. (2)since引导的是一个过去时的句子,说明自当时以来到现在(自从两年前以来),主句一般要用现在完成时。 Eg: I have learned more th
