它们可以用来修饰动词、形容词和副词,从而增强句子的表达力和准确性。

英语八类状语从句的用法归纳
英语八类状语从句的用法归纳一、概说状语从句即指在主从复合句用作状语的从句。
按照其意义,状语从句可分为时间状语从句、地点状语从句、原因状语从句、目的状语从句、结果状语从句、条件状语从句、让步状语从句等。
状语从句是高中英语学习中的一个语法重点,也是历年高考重点考查的内容之一。
学习状语从句主要应注意引导状语从句的从属连词的用法与区别,以及从属连词在一定的语言环境中的意义与用法。
二、时间状语从句1.引导时间状语从句的从属连词很多,常见的有before, after, when, while, as, since, till, until, as soon as 等。
2.表示“当…时候”的while, when, as 的用法区别是:while从句中的谓语动词必须是延续性动词;表示带有规律性的“每当”或当主、从句谓语动词的动作发生有先后时,只能用when;当表示“一边…一边…”或“随着”时,只能用as。
另外,用于此义的as 所引导的时间状语从句谓语只能是动作动词,不能是状态动词。
如下面一道高考题的答案是B 而不能是A:“I’m going to the post office.” “_____ you’re there, can you get me some stamps?”A. AsB. WhileC. BecauseD. If3.until 在肯定句中通常只连用延续性动词,表示相应动作结束的时间;在否定句中通常连用非延续性动词,表示相应动作开始的时间,意为“直到…才”。
如:He waited until she was about to leave. 他等着一直到她准备离开。
I did not begin to work till he had gone. 他走了后我才开始工作。
4.表示“一…就”除用as soon as 外,还可用the minute, the second, the instant, immediately, directly, i nstantly, no sooner…t han, hardly…w hen 等。

连词与状语从句知识梳理
连词与状语从句知识梳理连词与状语从句知识梳理知识梳理知识点1:一、连词含义连词是一种虚词,不能担任一个句子成分。
它主要是包括并列连词和从属连词。
二、具体用法1. 并列连词1). 并列连词的功能:连词在句中主要起连接词与词、短语与短语及句子和句子的作用。
即,连接两个平行的成分或句子。
如:and, but, or, nor, so, therefore, yet, however, for, as well as, both…and, not only…but also, either…or, neither…nor, (and)then等等。
2). 并列连词的用法:表示连接两个共同概念and 和or1) 并列结构中,or 通常用于否定句,and 用于肯定句。
2) 但有时and 也可用于否定句。
请注意其不同特点:There is no air or water in the moon.There is no air and no water on the moon.在否定中并列结构用or 连接,但含有两个否定词的句子实际被看作是肯定结构,因此要用and 。
both …and 两者都(两者都强调,谓语动词为复数)not only…but (also),不但…而且(强调后者,就近原则)注意:not only… but also关联两个分句时,一个分句因有否定词not 而必须倒装。
Not only does he like reading stories, but also he can even write some.neither …nor 意思为" 既不……也不……" (就近原则)Neither you nor he is to blame.as well as也 (强调前者,就远原则)The students as well as their class teacher like watching football matches very much.I have one of his plays as well as a few of his novels.表示选择的并列结构1) or意思为" 否则" 。
