或非正式文体中常省略。但如果跟第二个宾语从句时,连词that则不省。
eg: We know (that) the earth is round and that it travels around the sun.

C. whichever D. whenever (1) 同位语从句的定义
同位语从句一般放在名词(fact, news, idea, truth, hope, problem, information, belief, thought, doubt, promise, question)的后面, 对名词作进一步的解释、
说明。引导同位语从句的词有连词that, whether ,
连接代词who, what,连接副词how, when, where, why 。 同位语从句 the Appositive clause ① 由that引导
eg: The hope that he may come here is not gone yet.② 由whether引导
eg: The question whether we need more time to work has not been
discussed.⑵ 同位语从句的表现形式:③ 由when,where,how,why引导
eg: I have no idea when they will go.④有时可用 namely (即), that is to say (也就是说), in other words (换
句话说), that is (那就是), for example 等引出。
eg: He told us the good news, namely, the museum is open to all.
同位语从句与定语从句的区别:1.同位语从句说明的名词大都是抽象名词;
定语从句所修饰、限定的名词或代词有抽象的也
有不抽象的。
2.同位语从句所说明的名词与从句没有逻辑关系;
定语从句所限定的名词是从句逻辑上的主语、宾
语、表语、定语、状语等。
3.引导同位语从句的连词that不可省略;
引导定语从句的关系代词that作宾语时常可省略。区别下列句子哪些是同位语从句, 哪些是定语从句。 1. The fact that Great Britain is made up of three parts is known to many. 2. The news that is spreading around the airport is that a heavy storm is coming. 3. The suggestion that students should learn something practical is worth considering. 同位语从句定语从句同位语从句1.
