高中英语语法知识词法部分讲解---------连词及练习 一、概念
连词(conjunction.)是用来连接单词,短语,从句或句子的词。连词是虚词,所以不作成分。 二、连词的分类:
1.连词按其构成分为: 1)简单连词, 如: and, or, but, if, because ect. 2)关联连词, 如:both…and, not only…but also ect.
3)分词连词, 如: supposing, considering, provided ect.
4)短语连词, 如:as if, as long as, in order that ect.
2.连词按其性质分为 1)并列连词, 如: and, or, but, for ect. 用来连接并列的单词、短语、从句或分句。
2)从属连词, 如: that, whether, when, although, because ect. 用来连接名词性从句或状语从句。
三、连词的用法:
并列连词:
1.表示并列关系的连词有: and, both…and…, not only… but also…,neither…nor…和as well as等。
1) and: 和,并且
A:基本用法:
\表示 \和\并且\的意思,用来连接对等关系的字和字,片语和片语,句子和句子.
eg.①I enjoy basketball , football and table tennis. ②The weather becomes colder and colder.
③He didn’t go and she didn’t go either. 他没去,她也没去。
B:特别用法:
祁使句后连接and,有条件句作用,此时and=if you…, you'll… straight on, and you'll see the library.=If you go straight
on, you will see the library.
2) both…and… : 既…也…,(两者)都…
A and B + 谓语 (构成的词组作主语时,谓语动词用复数)。
eg.① Both Jim and Kate are from England. ② He both speaks and writes Spanish.
③ A man should have both courage and perseverance. 一个人即应有勇气也要有毅力。
④ Both New York and London have traffic problems. 纽约和伦敦都存在交通问题。 …and…否定句表示部分否定.
eg.①You can't speak both German and English. ②Both my father and my mother aren't doctors. 3) neither…nor… :既不…也不…
** Neither A nor B + 谓语( 与B相一致, 即连接两个并列主语时,谓语动词即采取就近原则。)
eg.①Neither I nor he has seen the play before. ② She couldn’t speak the language, nor could she write it.
