表语从句中that能省吗?

表语从句中that是否可以省略,需要根据以下几点判断:

1. 从句中是否有介词短语或副词做主语或宾语,如果有,则不能省略that。例如:The reason (that) in his mind is not clear. 不能省略that。

2. 从句中主语是否是疑问代词who或which引导的从句,如果是,则不能省略that。例如:The problem (that) who caused needs to be found. 不能省略that。

3. 从句中是否有并列结构或强调结构,如果有,则建议不省略that。例如:The rumor (that) John lost his job and quit school is not true. 建议不省略that。The truth (that) it was Tom that saw her last. 建议不省略that。

4. 如果从句中that前面有介词,则必须省略that。例如:The reason for (that) he refused is unclear. 必须省略that。

5. 如果从句是explanation或result的表语从句,且主句的主语是idea, fact, opinion, belief, view, feeling 等表示思维的词,则可以省略或保留that。例如:My view (that) he will win the election is probably right. 可以省略或保留that。

6. 如果从句起到修饰主语或宾语的定语从句作用,且属于非限定性定语从句,则必须省略that。例如:The news (that) the war would end soon spread quickly. 必须省略that。

综上,表语从句中可以省略that的情况有限,主要是当以上条件满足且从句意思明确时,可以选择性地省略that。但在翻译和写作中,为使句子更加严谨和书面化,建议从句中的that尽量不要省略。
