题目

All buses ______ because of the heavy snow,they had to to there on fo
All buses ______ because of the heavy snow,they had to to there on foot.
a、had been canceled
b、having been canceled
c、were canceled
d、having canceled
此题选B,但我想问为什么不能选C .选C就是两个独立句子啊!请讲出为什么

答案

选C不是两个独立句子.
如果是两个独立句子的话,那么后面那个是一定要加and的.但是这里没有,所以C肯定是错的.
这里是分词作状语.
意思是：所有的巴士都已经被取消了因为这场大雪,他们不得不走路去那里.
注意：没有连词的话就不能算作两个独立句子.我再给你看看两个独立句子的正确写法.
All buses were canceled because of the heavy snow, and they had to go there on foot.
翻译：所有的巴士都已经被取消了因为这场大雪,所以他们不得不走路去那里.
前面那种没有连词,所以不能是两个独立句子,因为原句当中没有缺主谓结构,而英文当中不允许一个当中出现两套主谓结构.这样的话必须用分词作状语了.
