初中英语定语从句

定语从句有限制性和非限制性两种。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确；非限制性定语从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开，例如： This is the house which we bought last month. 这是我们上个月买的那幢房子。（限制性） The house, which we bought last month, is very nice.这幢房子很漂亮，是我们上个月买的。（非限制性） 2）当先行词是专有名词或物主代词和指示代词所修饰时，其后的定语从句通常是非限制性的，例如： Charles Smith, who was my former teacher, retired last year. 查理·史密斯去年退休了，他曾经是我的老师。 My house, which I bought last year, has got a lovely garden. 我去年买的的那幢房子带着个漂亮的花园。 This novel, which I have read three times, is very touching. 这本小说很动人，我已经读了三遍。

3）非限制性定语从句还能将整个主句作为先行词，对其进行修饰，这时从句谓语动词要用第三人称单数，例如： He seems not to have grasped what I meant, which greatly upsets me. 他似乎没抓住我的意思，这使我心烦。 Liquid water changes to vapor, which is called evaporation. 液态水变为蒸汽，这就叫做蒸发。说明：关系代词that和关系副词why不能引导非限制性定语从句。

初中阶段英语状语从句的语法

这是去年去支教总结的，希望有所帮助啦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.

1、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 don't 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.

2、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.

3、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 can't carry it.

4、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.
