我觉得如果是分开的两句话,或者口语的话B没错.但是如果是书面用语,两个相互独立句子要成一句话必须用连词连接起来,或者so,或者therefore,但是题目中没有连词,所以此题只能用独立主格结构,即D.
你好。如果是B,句子必须是：
1 All the flights_B___because of the snowstorm, SO we had to take the train instead.
或者：
2 AS all the flights__b__because of the snowstorm, we had to take the train instead.
---------必须要有连接词。
