Question

The flight was delayed by the storm，     the passengers had to wait at the airport．（　　）

A. but

B. or

C. so

D. for

Answer 1

答案：C
观察句子的结构，前后是两个独立的句子，结合选项中间应用连词连接；根据前后句子的意义对比，The flight was delayed by the storm（航班被暴风雨耽搁了）及the passengers had to wait at the airport（乘客们不得不在机场等候）可知前句是原因，后句是导致的结果，因为航班被暴风雨耽搁了，所以乘客们不得不在机场等候，所以此处应用连词so，表结果，意为“因此，所以”．故选C．
