语法研究:同位语从句

课前自学( SB P37 Discovering useful structures 语法知识精讲

1. 同位语从句是名词性从句的一种,常用隶属连词 that 引导,( when, where, who 等也可

引导),常常跟在 fact, idea, opinion, news, hope, ability, patience, answer, order, report, wish,

decision, suggestion, belief, doubt, fact, hope, message, promise, question, reply 等名词后。

同位语从句一般用来讲解或说明这些名词的详尽含义或内容。在逻辑上表现为同位关系。 比方:

① Finally the workers got an answer that the government could do nothing to raise their

wages. 工人们最后得知政府不会采用任何措施来增加他们的薪水。

② They are familiar with the opinion that all matter consists of atoms.

他们很熟悉这一见解,所有的物质都是由原子构成的。

2. 同位语从句与 that 引导的定语从句的差异:1)

从先行词来看

同位语从句与名词在本质上是同一的, 是形式与内容的关系, 该名词是需要做特别说明的抽象名词。比方:

They were delighted at the news that their team had won. 当听到他们的球队赢了的信息时,他们欣喜若狂。

逻辑关系: The news was that their team had won.

2) 从引导词来看

引导词 that 在同位语从句中是连词,只起连接作用,无详尽含义, that 不能省略;

在定语从句中是关系代词,他在从句中充当必然成分:主语或宾语,有详尽词意, 语时还可以够省略。试比较:

① The factory (that) we visited yesterday is a chemical one.

我们昨天参观的那家工厂是化工厂。 (that 在从句中作宾语 )

that

作宾

② The news that he will leave for Shanghai is true.

他将要去上海的信息是真的。( that 只起连接从句的作用。)

2) 同位语从句的简单判断方法

因同位语从句与其先行词在逻辑上是同位关系, 所以,我们可在名词和从句之间加系动

词 be, 使其能够构成一个新句子,若是切合逻辑,句子畅达,则句子为同位语从句;定语从句是不能够够用系表结构把先行词与从句连接起来的。比方:

The thief that the earth is flat is still held in some countries.

地球是扁平的这一见解仍旧在一些国家存在。 (The belief is that the earth is flat.)
