符合主将从现的句子,主语和谓语动词可以省略的

Question

如题所述

Answer 1

主将从现，主要是指：
在时间，条件状语从句中，主句用一般将来时太，从句要使用一般现在时态来代替一般将来时态。例如：
If it 【rains 】tomorrow,we 【will not go camping】.
这时，并不涉及到主语和谓语动词的省略。
涉及省略的情况之一是：
在时间，地点，原因，条件，方式，让步等状语从句中，如果从句主语和主句主语相同，
或者从句主语是it 时，从句的主语和谓语动词的一部分可以省略。例如：
The tree could have been alive if given more water in time.
=The tree could have been alive if【the tree/it had been 】 given more water in time.
While crossing the street,the boy was hit by a car.
=While【 the boy/he was crossing】 the street,the boy was hit by a car.
祝你开心如意！
