47. Why do some people oppose working from home?
- A. It discourages team spirit.
- B. It invades employees' privacy.
- C. It undermines traditional values.
- D. It negatively impacts productivity.
答案：D
答案句：Though employers are backed by a chorus of remote work advocates, others note the loneliness, reduced productivity and inefficiencies of extended remote work.
参考译文：尽管雇主们得到了一众远程工作倡导者的支持，但其他人指出了长期远程工作的孤独感、生产力下降和效率低下。
定位线索：题干“some people oppose”→答案句“others note”；文中“reduced productivity”对应选项D“negatively impacts productivity”。
解析：题干问为什么有人反对居家工作。答案句直接列出反对理由：孤独、生产力下降、效率低下，其中“reduced productivity”与D项“negatively impacts productivity”同义。A项“团队精神”未提及；B项“隐私”未提及；C项“传统价值观”无中生有。
49. What can we conclude from the author's calculations?
- A. There is no point in transferring office work to working from home.
- B. Employees can benefit as much from remote working as their employers.
- C. Employers' gain from remote working should go to employees as compensation.
- D. Effective measures should be taken to motivate employees to set up offices at home.
答案：C
答案句：Rough calculations show that the savings made by employers when their staff works from home are of similar value to the compensation workers should receive for setting up offices at home.
参考译文：粗略计算表明，员工居家工作时雇主节省的开支与员工在家设立办公室应获得的补偿价值相当。
定位线索：题干“author's calculations”→答案句“Rough calculations”；文中“savings made by employers”与“compensation workers should receive”对应选项C“employers' gain...should go to employees as compensation”。
解析：题干问从作者计算中能得出什么结论。答案句指出雇主节省与员工应得补偿价值相当，隐含雇主节省应作为补偿给员工，对应C项。A项“没有意义”过度推断；B项“员工受益同样多”偷换概念，文中是补偿而非受益；D项“激励员工”无中生有。
50. What is the author's opinion on working from home?
- A. It should be avoided if possible.
- B. It is only a temporary measure.
- C. It can reduce companies' real estate costs.
- D. It may affect employees' corporate loyalty.
答案：A
答案句：When employees are properly compensated, employers' real estate savings will be modest. If savings are modest, then the many advantages of working in offices-such as lively atmosphere, rapidity of communication, team-building and acclimatization (适应环境)of new employees-will encourage employers to shelve the idea of remote work and, like Yahoo in 2013, encourage employees to work most of the time from corporate office space.
参考译文：当员工得到适当补偿时，雇主的房地产节省将是有限的。如果节省有限，那么办公室工作的诸多优势——如活跃的氛围、沟通的迅速、团队建设和新员工的适应——将鼓励雇主搁置远程工作的想法，并像2013年的雅虎一样，鼓励员工大部分时间在公司办公空间工作。
定位线索：题干“author's opinion”→答案句“will encourage employers to shelve the idea of remote work”；文中“shelve the idea of remote work”对应选项A“It should be avoided if possible”。
解析：题干问作者对居家工作的看法。答案句表明作者认为办公室工作有优势，应搁置远程工作，即避免居家工作，对应A项。B项“临时措施”未提及；C项“减少房地产成本”是雇主观点，非作者态度；D项“忠诚度”无中生有。
