B和C的区别在于时态,
B是一般过去时表过去发生的动作或存在的状态,用法有很多点:其中若是追述逝去的人或事,常用一般过去时.
例如:The book was written by LiangShiqiu.
Lei Feng set a good example to the people throughout the world.
雷锋和梁实秋已不在人世,用的一般过去时.
在这一题中讲述的是已经逝去的人和事.
译成:要不是医生的精心治疗,他是活不到去年的.
说明该人已去世.
C是过去完成时表过去某一时间或动作以前已经发生或完成了的动作.它表示动作发生的时间是“过去的过去”
该题做法解释已然明了,过去完成时的用法就不在此处细讲了.
____for the doctor"s careful treatment ,he ____till last year .
____for the doctor"s careful treatment ,he ____till last year .
A if it is not ; can not he
B were it not ; cound not live
C had it not been;cound not have lived
D if they were not ;could not live 为什么选C不选B呢,我觉得If 省略了,两个都可以啊
A if it is not ; can not he
B were it not ; cound not live
C had it not been;cound not have lived
D if they were not ;could not live 为什么选C不选B呢,我觉得If 省略了,两个都可以啊
