   came about
2. B.
   brought in
3. C.
   stayed up
4. D.
   ended up

Answer 1

A
试题分析：考查词组：A. came about发生B. brought in引进，赚钱C. stayed up熬夜D. ended up结束，句型：How did it come about that…，怎么会…,句意：我永远不能理解我是怎么考试不及格的，因为我是好学生。选A。
考点：词组的考查没有捷径，只有加强平时的背诵，包括词组本身的含义，一词多义，以及词组和动词的搭配，做题时别忘了弄懂句意和上下文的逻辑关系，进行判断。学生平时要特别注意这方面的积累。
