that(conj.) ¹³ (that 引导同位语从句)

上句中的 that 从句不是定语从句,而是同位语从句,其中心词是 a warning(中心词与其同位语从句被介词短语 on the radio 分隔开了)。同位语从句与定语从句主要有以下几个区别:

A. 在定语从句中 that 是关系代词或关系副词, 充当从句中的一个成分(主语、宾语、状语等), 而在同位语从句中 that 是个连词, 不充当从句的任何成分(如你所提出的句子那样)。

B. 同位语从句所指的中心词大都是概括性的抽象名词, 如 fact, news, idea, suggestion, warning 等。

C. 同位语从句所指的对象与其中心词所指的对象是一致的。例如, a warning = a hurricane is likely to come(参见 appositive clause or attributive clause)。而 that 定语从句却是对其中心词所表达的概念进行限定或区分(参见 idea $^{3}$ )。请鉴别下列实例中 that 从句的类型:

1. His delay of an hour is due to the fact that the train met with a minor accident. (同位语从句) 火车出了点事故,他耽搁了一小时。

2. Several years later, word came that Napoleon himself was coming to inspect them. 几年以后，他们听说拿破仑要亲自来视察他们。

3. One of the men held the view that what the book said was right. 两个人中有一个认为书上说的是正确的。

4. The letter that I received yesterday was from my brother. (定语从句) 昨天我收到的信是我哥哥寄来的。

5. There's a feeling in me ____ we'll never know what a UFO is — not ever.
