[解析]
(1)B.推理判断题。根据第一段的 Well,it's something that you would rather not have anyone else know about.( 嗯,它是你宁愿不要让别人知道的事情。) 可知 "a skeleton in the close" 指的是不想让别人知道的事,可知"a skeleton in the close" 指的是一个秘密,故选B。
(2)A.推理判断题。根据第二段的 Yes,but people these days say that you are not a real Australian unless your ancestors arrived as prisoners.( 是的,但现在人们说,你不是真正的澳大利亚人,除非你的祖先是囚犯。)可知除非你的祖先是作为犯人来的,否则人们会说你不是一个真正的澳大利亚人,故从第二段我们能了解到关于澳大利亚人祖先是作为犯人被带到澳大利亚的,故选A。
(3)B.推理判断题。根据第三段的Just as she opened the door and reached in to hang a skirt,a bony arm stuck out from the dark depths and a bundle of white bones fell to the floor,Jessica's mother sank into a faint(晕倒)(正当她打开门,伸手去挂一条裙子时,一只瘦骨嶙峋的手臂从黑暗深处伸出来,一捆白色的骨头掉在地板上,杰西卡的母亲陷入了昏迷。)可知杰西卡的母亲是被衣柜里掉出来的白骨吓到了所以才晕倒的。故选B。
