五、 连 词

(一) 知识概要
连词是一种在句子与句子之间，短语之间以及名词等其他词语之间起连接作用的虚词，它不能单独作句子的成份。按其意义可分为并列连词和从属连词两大类。并列连词连接的双方是对等的。常有的并列连词有and, both…and, either…or, neither…nor， not only…but also, as well as等。但如果连接的两部分意义不趋向一致，意义有转折的并列连词有：but, however, while (而)，only (只不过)。还有表示选择关系的并列连词，如：or, or else, otherwise… 再有的是连接双方，互为因果，或表示前因后果的连词有：for, so, therefore (因此)，then等。从属连词在初中范围内常常用来连接名词性从句，如：that, if, whether, 其次用来连接状语从句。其中有原因状语从句，常用的连接词有：when while, as, since, before, after, once, as soon as, until, till 连接条件状语的连词有：if, unless, as long as 等，而原因状语的连接词有because, since, as, now that (既然)。目的、结果、方式、比较、地点等状语从句的连接词有：so that, so…that, such…that, as…as, than, where… 它们在句子与文章中几乎无处不见。

[易错点解析]
　　①关于not…until
　　He stayed there until it was very late.句中，stay是可延续性动词，所以不用not.
　　He didn‘t leave until it was very late.句中，leave是不可延续性动词，所以用not
　　②because， so；although， but
　　上面已经提到，because和so及although和but不连用。
　　例如：Because he was late，he didn‘t catch the first bus.
　　一定不可以说Because he was late， so he didn‘t catch the first bus.
　　③or还是and
　　祈使句＋or＋陈述句 前后是对立的 祈使句＋and＋陈述句 前后是统一的
　（or或and后的陈述句，常用一般将来时）
　　Study hard， or you won‘t pass the exam.
　　Study hard， and you will pass the exam.
　　两句都可以转换成“If条件句＋主句”形式，注意：要去掉or和and：
　　If you don‘t study hard， you won’t pass the exam.
　　If you study hard， you will pass the exam.
　　④because， since， as， for表示原因时的区别
　　尽管because， for， since， as都表示原因，但是用法上有不同。
　　because 通常表示说话人认为这种理由或者原因是听话人所不知道的。
　　如：He didn‘t attend the meeting because he had too much work to do.
since表示的原因是人们已知的事实，常译作“既然”。
　　如：Since he can‘t answer this question， you’d better ask someone else.
　　as表示原因与since差别不大，只是语气更弱， 多译为“由于”
　　如：As I haven‘t seen the film， I can’t tell you what I think of it.
　　for表示因果关系时，只能放在主句之后，不能放在句首。而且经常是对主句补充说明理由或推断原因。
　　如：It rained last night， for the ground is wet.
　　⑤ as， when， while
　　when意思是“在……时刻或时期”，它可以兼指“时间点”与“时间段”，从句的动词既可以是可延续性动词也可以是不可延续性动词。
　　如：When I got home，he was having supper. When I was young，I liked dancing.
　　as意思是“边……边……”或“与……同时”，重在表示动作同时发生伴随进行。
　　如：They talked as they walked.
　　while只指“时间段”，不指“时间点”，从句的动词只限于延续性动词。
　　如：While I slept a thief broke in.
