问题补充：

When the woman came back home, she had no idea how it that her husband met with trouble again.

A. came about

B. came out

C. came up

D. came across

答案：

(答案→)A. came about

B. came out

C. came up

D. came across

解析：come about“发生”常与how连用，题中it是形式主语，后面的that从句是真正的主语。另外，come out出现、出版、(消息)传开、冲洗、罢工、(颜色或污点)被洗去、结果是(right/wrong)；come up走过来、出现、发生、被提出、(彩票)中奖、(太阳)升起；come across偶然遇见、无意中发现。
