英语连词用法归纳一、概说连词是一种虚词，用于连接单词、短语、从句或句子，在句子中不单独用作句子成分。连词按其性质可分为并列连词和从属连词。并列连词用于连接并列的单词、短语、从句或句子，如and, but, or, for等；从属连词主要引出名词性从句(主语从句、宾语从句、表语从句等)和状语从句(时间状语从句、条件状语从句、目的状语从句等)，引出名词性从句的连词如that, whether等，引出状语从句的连词如when, because, since, if 等。二、并列连词的用法（并列句是由and, but, or, for等并列连词把两个或两个以上意义相关的简单句连在一起而构成的句子。其结构为：简单句+并列连词+简单句）1. 表示转折关系的并列连词。这类连词主要有 but, yet 等。如：Someone borrowed my pen, but I dont remember who. 有人借了我的钢笔，但我不记得是谁了。He said he was our friend, yet he would not help us. 他说他是我们的朋友，但却不肯帮助我们。2. 表示因果关系的并列连词。这类连词主要有 for, so 等。(for表示结果通常不能放句首，也不能单独使用。)如：The child had a bad cough, so his mother took him to the doctor. 这孩子咳得很利害，所以他妈妈带他去看医生。You should get rid of carelessness, for it often leads to serious errors. 你们一定要克服粗枝大叶，因为粗枝大叶常常引起严重的错误。3. 表示并列关系的并列连词。这类连词主要有 and , or , eitheror , neithernor , not onlybut (also)不仅而且 , bothand , as well as 等。如：He did not go and she did not go, either. 他没去，她也没去。Both New York and London have traffic problems. 纽约和伦敦都存在交通问题。It is important for you as well as for me. 这对你和对我都很重要.三、从属连词的用法（可用来连接词与词、短语与短语、主句与从句。从属连词连接从句时主要连接宾语从句和状语从句。1.引导时间状语从句的从属连词 (1) 表示“当时候”或“每当”的时间连词。主要的 when, while, as, whenever。如：Dont talk while youre eating. 吃饭时不要说话。He came just as I was leaving. 我正要走时他来了。 (2) 表示“在之前(或之后)”的时间连词。主要的有before, after。如：Try to finish your work before you leave. 离开前设法把工作做完。 (3) 表示“自从”或“直到”的时间连词。主要的有since, until, till。如：Hold on until I fetch help. 坚持一下，等我找人来帮忙。 (4) 表示“一就”的时间连词。主要的有as soon as, the moment, the minute, once, no soonerthan, hardlywhen等。如：Ill let you know as soon as I hear from her. 我一接她的信就通知你。The moment I have finished Ill give you a call. 我一干完就给你打电话。2. 引导条件状语从句的从属连词。这类连词主要有if, as so long as,等。如：Do you mind if I open the window? 我开窗你不介意吧?As long as youre happy，it doesnt matter what you do. 只要你高兴，你做什么都没关系。注意：在条件状语从句中，通常要用一般现在时表示将来意义，而不能直接使用将来时态。不过，有时表示条件的 if之后可能用 will，但那不是将来时态, 而是表示意愿或委婉的请求(will为情态动词)。如：If you will sit down for a few moments, Ill tell the manager youre here. 请稍坐, 我这就通知经理说您来了。3. 引导目的状语从句的从属连词。主要的有so that等。如：He raised his voice so that everyone could hear. 他提高了嗓音，以便每个人都能听见。4. 引导原因状语从句的从属连词。主要的有because, as, since,等。如：Since weve no money, we cant buy it. 由于我们没钱，我们无法购买它。5. 引导让步状语从句的从属连词。主要的有although, though, even though, even if, while, however, whatever, whoever, whenever, wherever等。如：Although they are twins, they look entirely different. 他们虽是孪生, 但是相貌却完全不同。You wont move that stone, however strong you are. 不管你力气多大, 也休想搬动那块石头。6. 引起名词从句的从属连词。主要有that, whether, if 等，它们用于引导主语从句、表语从句、宾语从句和同位语从句。其中that 不仅没不充当句子成分，而且没有词义，在句子中只起连接作用；而 if, whether 虽不充当句子成分，但有词义，即表示“是否”。如：I wonder if its large enough. 我不知道它是否够大。1.
