題目

According to the passage, which of the following statements is true? A. The alarm clock was patented by an American inventor in 1787. B. People continued to hire knocker-ups even after the alarm clocks were invented. C. In Britain and Ireland today, knocker-ups are still doing their jobs in industrial towns. D. During their morning patrols, police officers would watch out for knocker-ups’ safety.

官方答案

• 答案：B. People continued to hire knocker-ups even after the alarm clocks were invented.

解析

文中指出，1787 年美國人 Levi Hutchins 雖發明鬧鐘，但當時尚未普及於英、愛一般大眾，人們仍普遍雇用 knocker-ups；1847 年 Redier 取得可調式鬧鐘專利後，機械鬧鐘仍不便宜，直到 1920 年代多數英國工人仍寧可雇用敲門人，故 B 正確。A 錯在 1787 年是「發明」而非取得專利，專利是 1847 年 Redier 所取得。C 錯，1950 年代後此行業已因電力普及與平價鬧鐘而消失。D 錯，警察是為賺外快而兼差，並非維護敲門人安全。
