语法讲解
【语法51】同位语从句
同位语从句用来说明前面某个抽象名词的具体内容，常用 that 引导，有时也用 whether。that 在从句中不作成分，只起连接作用，一般不能省略。
| 先行名词 | 例句 |
|---|---|
| news | I heard the news that he got promoted.（我听说他升职的消息） |
| fact | We can't deny the fact that prices are rising.（我们无法否认物价在上涨的事实） |
| idea | Do you agree with the idea that money brings happiness?（你同意金钱能带来幸福这个观点吗？） |
| rumor | There is a rumor that the concert will be cancelled.（有传言说音乐会将取消） |
| question | The key question is whether we can finish on time.（关键问题是我们能否按时完成） |
同位语从句 vs 定语从句
| 类型 | 作用 | that 是否作成分 | 例句 |
|---|---|---|---|
| 同位语从句 | 解释名词的具体内容 | 不作成分，不可省略 | The news that he resigned surprised us. |
| 定语从句 | 修饰限定名词 | 作主语/宾语，作宾语可省略 | The news (that) he told me surprised us. |
判断技巧：把 that 去掉后，如果从句仍然完整（主谓宾齐全），就是同位语从句；如果缺少主语或宾语，就是定语从句。
