I am a student which you all know. 领先行词与关系词被割裂时是如何表现的。如：Today, stepladders carry labels several inches long that warn, among other things, that you might - surprise! - fall off. 找先行词的方法。反证法。把它带进去。哪一个是通顺的，哪一个就是先行词。 1. 翻译定语从句。 2. 结合先行词的结构特点和位置特征在关系词之前寻找与定语从句的意思的有逻辑 关系相符合的词。 二、定语从句里面的关系代词的用法。 1.常用的关系代词：which, that, who, whom。Whom 现在用的很少。前面有介词只能用 which，不能用 that。 2. 关系代词在考试中的特殊情况。 What:1)它是子母同体。相当于一个关系代词以及一个先行词。What 前面不应该在出现 先行词。 如果前面已经偶一个关系词，就不能用 what 来引导。例如：You can have everything what you like. what=all that,所以这儿不能用 what. All-is a continuous supplying of the basic necessities of life A. what is the need B. the things need C. for our needs D. that is need 2)what 单独使用，后面不加名词。 例如：She is not what she used to be. 3)what 后面加名词 例如：What money I have has been given to you. 1997 年考题：_he knows about it is out of date and in accurate A.

A.what B.when C.which D.that 3)多重的名词从句现象。例如： I realized that what I said was not exactly what meant to say. 考题：Prof. Lees book will show you _ can be used in other contexts. A that you have observed B that how you have observed C how that you have observed D how what you have observed 二、名词从句中的主语从句 主语从句有如下几种表示方式： 1.用 which, that 放在句首引导主语从句。例如： That the seas are being overfished has been known for years. 3.用 it is +ved+that例如： It is believed that you are good boy. 3. 用 whether 引导主语从句。例如： Whether the eyes are the windows of the soul is debatable. 三、宾语从句 需要掌握的几点： 及物动词后面的宾语从句。2005 年例句： Do you remember all those years when scientists argued that smoking would kill us? 四、表语从句 就是一句话做另一个句子的表语。就是把从句放在系动词的后面。1997 年例句： A report consistently brought back by visits to the US is how friendly, cautious and hopeful most Americans were to them. 五、同位语从句 考研 1 号系列图书?考研真相?写作 160 篇?阅读根底 90 篇? 考研 1 号英语精品，祝您考研成功！ 就是用来补充说明同位语的名词成分的句子。结构是：名词+that+从句。 同位语从句与宾语从句和定语从句的区别：引导宾语从句和定语从句的的 that, which 可以省 略，而引导同位语从句的 that 不能省略。定语从句中的 that 必须在从句中扮演主语或者宾语。 同位语从句的 that 不扮演任何成分。例如： There is a popular saying that family instability causes social instability. that 不做句子成分。 状语从句 1.状语从句的本质。就是用一个句子来作另外一个句子的状语。 状语从句的分类：时间状语、地点状语、原因状语、结果状语、目的状语、条件状语、让步 状语、比较状语、方式
