英语连词知识点总结一、并列连词并列连词用来连接平行对等(即互不从属)的词、词组或分句。
按照并列连词在句子中的作用可分为:并列关系,转折关系,选择关系,因果关系。
基本并列连词如and, or , but , 关联连词如either...or , neither...nor , not only...but also,both ...and, whether...or 等;介于并列连词与从属连词或介词之间的结构如 as well as , as much as, rather than , more than, no less than 等;此外还有些'半连接词',一些语法学家把它们称为连接副词,如 nevertheless, however, meanwhile, otherwise, likewise 等,在句中做连接性状语。
这类连词主要是从逻辑上,而不是从形式上连接句子,其关系比较松散。
并列关系的连词有:and, both…and, not only…but also, as well as, and…as well, not…nor, neither…nor等。
1.and的基本用法是表示并列和对称关系。
例4 He sang and played the guitar. 他一边唱歌一边弹吉他。
(1)两个对等的宾语或状语之间,在肯定句中用and,但在否定句中,不用and,一般用or或nor。
例5 Our college is not in Beijing or Shanghai. 我们的学院既不在北京也不在上海。
(2)当一个句子中出现了两个否定词时,应该用and连接并列成分。
这时and表示的也是全部否定。
例6 He did not talk loudly and also not clearly. 他说话声音不大,也不清晰。
(3)and用来连接条件分句和结果分句,意思是“……,那么……”。
