Question

10. It's already 10 o'clock. I wonder how it        that she was two hours late on such a short trip.

   A. came over   B. came out

   C. came about   D. came back

Answer 1

10. C句意为："已经十点了。我想知道这么短的路程她怎么会迟到两个小时。"how暗示该空表示"发生"，因此应填came about;。 come about相当于happen ,意为"发生"；come over 意为"过来;顺便来访"；come out意为"出来; 出版"；come back意为"回来"。
