同位语
一个名词或代词后面有时可以跟一个名词 (或起类似作用的其他形式),对前者进一步说 明它指的是谁,是什么等,那么这一部分就叫 做同位语。同位语与被它补充说明的词的格要 一致,并常常紧挨在一起。 它可以是单词、短 语或从句。

Ⅰ.同位语的表现形式
1.通常用逗号将同位语与其所修饰的先行 词隔开,表示一种普通的同位关系。
①This is Mr.Black,director of our hospital.
这是布莱克先生,我们医院的院长。
②She is a good teacher,the friend of yours.
她是一位好老师,也是你们的朋友。

2.有时也可用破折号或冒号引导同位语。 用破折号,停顿较长,对同位语起强调的作用; 用冒号,停顿最长,强调的作用更大。
①The orphan's daily necessities—clothes, food,etc.—are supplied by a kind-hearted teacher.
这名孤儿的日常用品——衣服、食物等等—— 由一位好心肠的老师提供。
②In a sense,nouns can be divided into two kinds: the countable noun and the uncountable noun.
在某种意义上,名词可分为两类:可数名

3.有时,同位语之前带有引导词,表示同 位成分之间的特殊意义。常见的同位语引导词 有as,or,chiefly, especially,for example, for instance,in short,mainly,mostly, namely,that is,in particular,in other words, including,that is to say,such as,say, particularly,what,which,who,when, where,why,how,that,whether等。
①Only one person can do the job, namely you.
只有一个人能做这项工作,那就是你。
②You can buy fruit here,for example,

4.另外,无需借用任何引导词或标点符号, 而将同位语直接置于先行词之后。
①I have the honor to introduce John's sister Jane to you.
我很荣幸地向你介绍简,约翰的妹妹。
②Tom gave his friend John a book. 汤姆给了朋友约翰一本书。

Ⅱ.用名词、代词或数词及其短语作同位 语
同位语有限制性和非限制性两种,限制性 同位语和前面的词关系比较密切,中间不能停 顿;非限制性同位语与前面的词关系比较疏散, 常用逗号把它们分开,表示略有停顿。
We teachers should be responsible for this.(名词作同位语)
我们老师应该对此负责。
Mr.Robson,our head teacher,is from Canada.(名词作非限制性同位语)

They each put forward a proposal.(代词 作同位语)
他们每个人提出了一个建议。 You may leave it to us two.(数词作同位语) 你可以把它留给我们两个。 注意:多数的同位语都属于限制性同位语。

Ⅲ.同位语从句
1.同位语从句跟在一个名词后,对其作进 一步解释;能跟同位语从句的名词常见的有: announcement,belief,discovery,doubt, excuse,fact,fear,hope,idea,knowledge, news,order,promise,problem,proof, proposal,possibility,question,reply, remark,reason,report,rumour,story, suggestion,thought,truth 等。引导同位语从 句的连词最常用的是that,除此之外还有how, when,where,why,whether等。

①The announcement that a new airport was to be built nearby aroused immediate opposition.
说要在附近建造新机场的通告马上引起了 反对。
②The suggestion that shops should open on Sundays led to a heated discussion.
关于商店星期日也应该营业的提议,引起 了激烈的争论。

2.为了保持句子平衡,同位语从句有时可 以不紧跟在它所说明的名词后面。
①The story goes that William Tell killed the tyrant with an arrow.
传说威廉·泰尔用箭射死了暴君。
②Suddenly the thought came to me that he could go blind.
突然我有一种顾虑:他可能会瞎。

3.在表示建议、命令、请求、主张、目的、 愿望等名词后面的同位语从句中,谓语动词必 须采用虚拟语气结构,即:(should+)v.
①He gave orders that the work(should)be started immediately.
他发出指示要立即开始工作。
②Her suggestion is that we(should)give up the plan.
她建议我们应该放弃这个计划。

Ⅳ.同位语从句和定语从句的差异
1.定语从句中的that既代替先行词,同时 在从句中担任某个成分(主语或宾语),而同位 语从句中的that是连词,只起连接主句与从句 的作用,不充当句中任何成分。
①Have you forgotten about that money(that)I lent you last week?
你忘了上星期我借给你的钱了吧?(定语从 句)
②The thought came to him that Mary had probably fallen ill.

2.定语从句是形容词性的,其功能是修饰 先行词,对先行词加以限定,描述先行词的性 质或特征;同位语从句是名词性的,其功能是 对名词进行补充说明。
①The news that he told me is that Tom would go abroad next year.
他告诉我的消息是汤姆明年将出国。(定语 从句)
②The news that Tom would go abroad is told by him.
汤姆将出国的消息是他讲的。(同位语从句)
