大学英语语法12——状语从句
英语状语从句要点归纳
英语状语从句要点归纳英语状语从句要点归纳一、概念修饰主句中的谓语动词，形容词或副词等的从句叫状语从句。
状语从句的语序应是主语+谓语+其他成分，即陈述句的语序。
状语从句的位置，可以放在主句前面或后面，若放在主句前面，要用逗号与主句分开；主句若是疑问句，那么时间状语从句只能放在主句的前面。

She has taught in this school since she came to this city in 1989.自从一九八九年她来到这座城市以来一直在这所学校教书。
【注意】如主句是一般将来时，则表示将来的时间状语只用一般现在时（即“主将从现”原则）。
如：I'll write to you as soon as I get to Beijing. 我一到北京就将写信给你。
It will get warmer and warmer when spring comes. 春天来临时，天气将变得越来越暖和。
2. 原因状语从句原因状语从句由because, as, since等连词引导。

大学英语语法应用教程-从句(Clause)
从句(Clause)
If two numbers are to be added, it does not matter in which order they are added. 若要把两个数加起来，那么按哪种顺序相加是没有关系的。(需要注意的是，连接代词which并没有位于主语从句句首， 因为它在从句中作介词in的介词宾语和order的定语。而且，不要把由which引导的主语从句误认为是介词宾语从句。) It follows from Maxwell’s hypothesis that whenever there netic field is produced. 由麦克斯韦假设可知，每当电场发生变化时就产生磁场。 (it follows that … 意为“由此得知……；因此”。) It happened that she was out when he called.( = She happened to be out when … ) 他打电话时，她恰巧不在家。(It happens that可译成“碰巧，恰巧；发生”。)
从句(Clause)
3) 表语从句 主要位于系动词be之后的表语从句最为常见，当然，也可用seem, sound等。例如： The present conception of the general structure of the atom is that it consists of a kind of solar system. 现在对 原子的一般结构的看法是：它是由一种太阳系构成的。 All indications are that the need for skilled people in the field of electronics will grow in this new decade. 所有 的迹象表明，在这新的十年中对电子学领域熟练人员的需求量将会增长。 That is how a computer works. 这就是计算机的工作原理。 (本句中的that应译为“这”；how从句一般可译成“……的原理，……是如何……”) Predictions are that electronics will continue to grow at a rapid rate for some time to come. 预测表明，在未来 一段时期内电子学将会继续高速发展。 (That is why … 要译成“这就是……的理由；这就是为什么……；因此……”。) My plan is that we will finish the project by the end of the year. 我的计划是我们年底结束这个项目。 The conclusion of the discussion is that the proposal cannot be accepted. 讨论的结果是这个提议不能被接受。 在个别情况下，状语从句也可充当表语从句(特别是句型this is because … )。如： This is because you has been absent all the term. 这是因为你整个一学期缺勤的缘故。
