中考英语语法讲解：状语从句

　　状语从句是句子的状语由一个从句充当，来修饰主句中的动词，形容词或副词等。状语从句都由从属连词引导，与主句连接，放在句末时，一般不在前面加逗号。

　　状语从句根据它表示的意思可分为时间，原因，条件，比较，结果，目的等类。下面我们拣重点的一个一个来分析。

　　时间状语从句：是由when, as, while, after, before, since, until, as soon as 等从属连词引导的状语从句。时间状语从句中的谓语动词不能用一般将来时，只能用一般现在时表示将来发生的动作或存在的状态。 如:I will call you as soon as I arrive there.

　　原因状语从句： because, since, as和for都表示原因。常常令我们不知该用哪个好。我们来比较一下。because语势最强，回答why提出的问题，用来说明人所不知的原因。当能够很明显的看出原因或人们已知原因，就用as或since。如：I dont like that coat,because the color looks terrible. 由because引导的从句如果放在句末，且前面有逗号，则可以用for来代替。但如果不是说明直接原因，而是多种情况加以推断，就只能用for。如：He is not here, because / for his mother is ill.

　　目的状语从句：表示目的状语的从句可以由in order that, so that,等词引导。如：You must raise your voice so that/in order that everybody can hear you clearly.

　　结果状语从句：结果状语从句常由so...that 或 such...that引导，要掌握和区分这两个句型，首先要了解so和such后面分别跟什么词。such是形容词，修饰名词或名词词组，so是副词, 只能修饰形容词或副词。so 还可与表示数量的形容词many, few, much, little连用，形成固定搭配。如：The box is so heavy that I cant carry it.

　　让步状语从句：是由though, although 引导的状语从句。though, although 和 but不能同时使用。

　　Although it rained, they had a good time.
