How did it come _________ that you made a lot of mistakes in you

How did it come _________ that you made a lot of mistakes in your homework.
A、about
B、after
C、with
D、to
【正确答案】：A
【题目解析】：本题是说你怎么会在作业中犯这么多的错误。A项“come(about)发生，造成”(多用于how疑问句中，也可用于陈述句，在非正式英语中还可简化为How come+从句如How come you were late for class yesterday)符合题意。其他三项中，come after 紧跟，继...而来；come around“苏醒；顺访”；come to 想起，共计，都与题意不符。
