英语 语法 句法 从句
I could tell that if the stars were suns,they had to be very far away.
1.请分析句子结构,主、从句怎么看?
2.宾语从句“if the stars were suns,they had to be very far away”怎么解释?
答
1.从that开始是从句,tell的宾语从句.后面if开始是宾语从句中的虚拟语气的句子.if引导的是虚拟语气的状语从句.
2.如果这些恒星都是太阳的话,那么它们就应该离得很远.（虚拟语气）句子结构：1.主句：I could tell ；2.宾语是从句，且由that引导：if the stars were suns,they had to be very far away 其中，宾语从句是个复合句。宾从的“主句”部分为“they had to be very far away”，其次，是由 if 引导的条件状语从句，只不过，该状从的语气是虚拟语气，表说话者主观意愿上的猜测、推测、假设，并非客观存在的事实；3.句意：如您所述。对么？对。
