　　同位语表示与之同位的名词(短语)的实际内容，对前面的名词(短语)加以补充说明或进一步解释。
　　例如：
　　The suggestion that we should develop the natural resources in the region has been discussed.
　　关于我们应该开发本地区资源的建议已经讨论过了。
　　同位语从句的连接词
　　1. 引导同位语从句的连接词最常见的是that。
　　2. 连接词when, where, why, whether, how 等也可引导同位语从句。
　　例如：
　　Have you any idea how fast sound travels? 你知道声音传播有多快吗?
　　This is some doubt whether he will come. 他是否会来还不一定呢。
　　He had no idea why she left. 他完全不明白她为什么会离开。
　　3. 同位语从句中常见的先行词
　　idea, situation thought, fact, evidence, belief, doubt, fear, hope, question, theory, news, order, 等等。
　　注意：同位语从句和定语从句的区别
　　1. 修饰的词不同。同位语从句前的先行词比较有限，且大部分都是抽象名词;定语从句的先行词可以是比较复杂的内容，可以即包括人又包括物。
　　2. 从句的作用不同。同位语从句是用来解释前面的名词的，而定语从句则是修饰的作用。
　　3. 关系词的作用不同。同位语从句中that 是连词，不充当任何成分，但是不能省略。而定语从句中that 是充当一定成分的，在某些情形下是可以省略的。
　　翻译示例：
　　Many people have stopped buying it, ______________(尽管一再保证这种产品是安全的).
　　1. 介词短语作状语：所以前半部分作句子的状语
　　2. 尽管可以用一个介词短语，despite，后面应该接名词短语
　　3. 同位语从句：assurance后面接一个同位语从句对“保证”进行说明。
　　答案：despite repeated assurances that the product is safe

　　6. 此题为故意考查大家是否能辨别同位语从句与其他从句使用that的区别而设置。并不考查同位语从句。第一空为定语从句，why和that都可引导定语从句修饰the reason;第二空为表语从句，根据句意“……的理由是”只能选择that，如果because或why就意为“……是因为”句意不通，所以，答案为B。
