When the teacher knows what we have done, he will say that we have done a good deed. 当老师知道我们所干的事情时，他会说我们做了一件好事。

He didn’t tell us he came from Shanghai. 他没有告诉我们他来自上海。
He said he had read the book. 他说他读过这本书。
3)但当从句的内容是客观真理或客观事实，而不受时间的限制时，即使主句谓语动词为过去时，从句仍用一般现在时。如：

My advice is that you should go to apologize to him. 我的建议是你应该去向他道歉。
同位语从句学习指要
当名词后面所接的从句表示与名词同位并为名词的实际内容时，这个从句就是同位语从句。如：
The news that China has joined the WTO excited us all. 中国加入了世界贸易组织这一消息使我们大家兴奋不已。
He told us the truth that he fell down from his bike this afternoon. 他告诉了我们他从单车上摔下来这一真相。
连词：that，whether

3.同位语从句与定语从句的区别：
同位语从句与定语从句形相似而实质不同，具体表现在以下几个方面：
(1)被修饰的词不同。同位语从句的前面一般是数量有限的、表示抽象意义的名词；而定语从句的先行词是无数的指人或物名词。
(2)从句的作用不同。同位语从句表示同位名词的具体内容；而定语从句是对先行词—名词的限制、描绘或说明。
(3)引导词的作用不同。引导同位语从句的that是连词，在从句中不担任任何成分，但不能省略；而引导定语从句的that为关系代词，在从句中担任句子的某种成分，当担任定语从句中的宾语时，that可以省略。
(4)引导词不同。定语从句不能用what, how, whether引导；而同位从句可以用what, how, whether引导。
(5)判定定语从句和同位语从句的方法。同位语从句可充当同位名词的表语；而定语从句不能充当先行词的表语。
1. 由that引导

大学英语四级考试语法：—定语从句
大学英语四级考试语法：—定语从句 很多同学在大学英语四级考试中会存在一些误区，认为语法不那么重要，其实英 语语法是学习英语的指南，对我们帮助很大。以下是小编给大家整理的大学英语四级 考试语法：—定语从句，希望可以帮到大家 1、mary is a beautiful girl. 名词的扩展靠限定，最基本的就是在名词的前面增加一个形容词这样的定语，上 面的句子就是表语girl的前面加了一个形容词。显然，如果只是mary is a girl这样的 句子会让人觉得非常枯燥，没有什么意义，所传递的信息量极其有限。所以，名词前 面加定语，可以使被限定的名词更加生动，更加形象而富有生命。如果要对名词给出 更多限定，挖掘更多内部信息，我们可以在名词前面加多个定语来限定，如mary is a beautiful chinese girl. 放在名词前面起到限定作用的定语有很多种形式，形容词，名词，动词现在分词，动词过去分词等。虽然形式多样，但是这类定语还是比较好理解，只要顺着句子的顺序，就基本可以明白是怎么回事。 2、the computer that i bought yesterday works well. 有时候，我们需要对名词给出很多的说明，用大量的信息来限定名词。这时，如 果还是把长长的限定成分放在名词前面，就会头重脚轻，所以英语中会用跟在名词后 面的定语从句来限定前面的名词。根据定语的功能还可以分为限制性定语从句和非限 制性定语从句。两者的区别在于前者与被限定名词之间没有逗号，而后者则有逗号隔开;前者起到限定作用，不可或缺，后者起到补充作用，舍去后对剩余部分影响不大。 本句子通过“that i bought yesterday”这个that引导的定语从句，使得主语the computer得到限定而明确，是我昨天买的计算机而不是别的。如果明白了这个名词可 以通过后面加定语从句来扩展，我们的句子马上可以变得复杂起来，请看下例：another popular spectator sport, which is known as the sport of kings, is horse-racing, which is controlled by the jockey club. 译文：另一种以特大型运动著称的流行观赏运动是赛马，这种比赛由赛马总会控制。

英语四级定语从句讲义以及参考答案
定语从句讲议 一．什么是定语从句 1.定语从句(Relative Clause, Adjective Clause, Attributive Clause, Defining Relative Clauses, Restrictive Clauses ) 是一种由关系词(Relative Word) 引导的从句形式的后置定语。它分限定性和非限定性两种(Defining and Non-defining)。 2.关系词分关系代词(Relative Pronoun) 和关系副词(Relative Adverb)以及关系限定 词(Relative Adverb ). 二．限定性和非限定性定语从句在句法和语意上的区别 1．限定性定语从句对其所修饰的先行项(Antecedent) 起限制作用，不可缺少，否则句意不完全。主句和从句间不用逗号隔开。 2．非限定性定语从句只是对其所修饰的Antecedent提供有用的补充情况，缺了它，主句句意仍完整。主句和从句间用逗号分开，常用在书面语中，文体较正式。 三．关系词的分类 关系词分两类： 1．关系代词： WHO: refers to persons and used as a subject; WHOM: refers to sb. and used as an object WHICH: refers to sth. and as a subject, object and prepositional object THAT: often refers to sth. sometimes to sb. and a subject, object and prepositional object Note: THAT can’t be used to introduce a non-defining relative clause in an English Examination. 2.关系副词: WHEN: refers to time and used an adverbial. WHERE: refers to place or location and as an adverbial. WHY: refers to reason and as an adverbial. It can’t be used to introduce a non-defining relative clause. 3.Whose 是表示所属/所有权关系的关系词，是唯一的关系限定词。 4.As 是关系代词，可作主语，主补和宾语 四．Examples: ---- What’s the name of he blonde girl who just came in? --- Do you think one should stay faithful to the person to whom one is married? --- The brocks which fell off the roof caused serious damage. --- Where’s the money that I lent you? --- The man whose hair is long is an American movie star. --- We all look forward to the day when the scientists can discover more secret of the universe. --- This is the place where I found my lost watch. --- That is the reason why I don’t agree with you. --- The two combers, who were feeling exhausted, went back to their tent. --- The Chairman’s daughter, whose name is Ann, gave me a patient smile. --- We are going to settle in N.
