问题 This gold mine was discovered by accident.

选项 A、by air
B、by chance
C、at large
D、at ease

答案B

解析本题考查的是对近义短语的辨析。四个选项中，A选项by air的意思是“通过航空的方式”，一般用在描述使用的是什么交通工具的时候。C选项at large的意思是“一般来说，随便地，整个，全部”，如：The people at large want peace. 总的来说人民是渴望和平的。D选项at ease的意思是“自由自在、放松”，如：she felt completely at ease with Tom.她和汤姆在一起时感到十分放松。B选项by chance的意思与by accident一样，表示“偶然、意外”，因此B选项符合题意。
