　　Part C：仔细阅读

　　Passage One

　　46. For what reason may your friends feel reluctant to visit your home?

　　答案：A)The security camera installed may intrude into their privacy.

　　解析：本题为推断题，题干问“你的朋友可能会因为什么不愿意去你家”。由题意定位到文中“a relatively innocuous gadget may be turning friends and family away from your home”一句，下文提到摄像头(“The elephant…is your Internet-connected security camera”)并指出很少有人考虑这些装置对来客的影响(“But few stop to think about the effect these devices may have on house guests”)，可知定位句中让朋友家人远离你家的“gadget”正是可能会侵犯来客隐私的摄像头(security camera)。选项A为合理推断。

　　47. What does Lizzie Post say is new territory?

　　答案：D)Etiquette around home security cameras.

　　解析：本题为细节题，题干问“什么是Lizzie Post所说的新领地”。由显眼关键词Lizzie Post和newterritory定位到文中“’It’s certainly new territory, especially as home security cameras become easier to install,’ says Lizzie Post”一句，句中it指代前文所提家装摄像头的议题，又由下段段尾“’We’re conquering new territory in the world of etiquette,” says Post.’”明确新领地指”etiquette around home security cameras”。选项[D]为正确答案。

　　48. What is Lizzie Post mainly discussing with regard to the use of home security cameras?

　　答案：C)Likes and dislikes of individuals.

　　解析：本题为细节题，题干问“关于家用安全摄像头，Lizzie Post主要讨论了什么”。题目焦点模糊，可借助选项关键词定位，注意理解概括和同义替换。

　　49. What is a host's responsibility regarding security cameras, according to Lizzie Post?

　　答案：A)Making their guests feel at ease.

　　解析：本题为文中人观点题，题干问“Lizzie Post认为在安全摄像头的问题上，主人的责任是什么”。由关键词“host’s responsibility”可定位至文中“Post says it’s a host’s responsibility to make sure guests feels comfortable within their home”一句，同义替换，选项[A]为正确答案。

　　50. In what way can the home security camera benefit visitors to your home?

　　答案：B)It can prove their innocence.

　　解析：本题为细节题，题干问“家用安全摄像头能以何种方式有益于来客”。根据题意定位至文中“the air of accountability that the camera generates can also work in contractors’ favor”一句，下文提到若客人来访期间家中有不好的状况发生，来客并不想因此遭受指责(be blame for it)，而摄像头可以证明他们并没有偷钱(steal the $20)或打翻桌上的花瓶(knock the vase off the table)。由此可见选项[B]对原文文义进行了概括，为正确答案。
