初中英语六大从句用法及练习
(完整版)初中英语从句语法讲解
从句从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。
（参见以下各条）3、各从句在句子中的位置以及用法：(1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。
例如：That is why he did not come to school yesterday. / It is because you are so clever.(2) 宾语从句：在句子中作及物动词或介词的宾语。
①基本形式：（主句＋）连词+从句主语+从句谓语+...②关于宾语从句连词的选择：若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;若从句来源于一个一般疑问句,连词则用if 或whether;若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)例如：They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。
) (从句本来就是陈述句)/ I wonder whether I should saysomething for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。
) (从句来源于一般问句Shall I say something for him to the headmaster?)/ He asked mewhere he could get such medicine. (他问我在哪儿能搞到那样的药。
) (从句来源于特殊问句Where can he get such medicine? )③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时；如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。
如：I think Iwill do better in English this term. (我想本学期我的英语会学得好点。

初中英语语法从句专项讲解与练习
中考英语语法从句专项讲解与练习题一，宾语从句引导词：由that 引导的陈述句性的宾语从句，在很多动词如say，think，wish ，hope，see，believe，agree，expect，hear ，feel等动词后。

例：We think it wrong that he told a lie to everyone (我认为他向每一个人撒谎是错误的) B，由连词if、whether 引导的表示是否的宾语从句。

初中英语各类从句知识及示例
初中英语各类从句知识及示例从句不能单独成句，但它也有主语部分和谓语部分，是一个特殊句子，就像一个句子一样。
所不同在于，从句须由一个关联词引导。
根据从句语法功能的不同可分为：主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。
前四类由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，所以通称名词性从句；定语从句功能相当于形容词，称为形容词性从句；而状语从句功能相当于副词，称为副词性从句。
状语从句还可以分为条件状语从句、原因状语从句、地点状语从句、目的状语从句、让步状语从句、比较状语从句、方式状语从句、结果状语从句和时间状语从句。
主语从句（Subject Clause）用作主语的从句叫主语从句。
引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。
如：That the earth is round is true.地球是圆的是真的表语从句（Predicative Clause）用作表语的从句叫做表语从句。
引导表语从句的关联词与引导主语从句的关联词很多都一样。
如：My opinion is that you should not go alone.我的意思是你不应该单独前往。
宾语从句（Object Clause）在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类：动词的宾语从句、介词的宾语从句和形容词的宾语从句。
如Do you know where he lives?你知道他住哪吗同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一，从句作同位语表示与之同位的名词(短语)的实际内容，它的作用相当于名词，对前面的名词(短语)加以补充说明或进一步解释，相当于一个表语从句，它们之间的关系就是同位关系，即主表关系。
如The fact that the earth is round is true.地球是圆的，这件事是真实的，That用于解释fact.定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。
