研究所、轉學考(插大)、學士後-英文題庫下載題庫

解析：

這道題目考察的是代詞用法的正確性，特別是關係代詞「whom」和「which」的使用，以及數量詞「majority」、「most」、「all」與其後的名詞的搭配是否正確。

選項分析：

• (A) So far the manager has interviewed fifty applicants, one of whom has a doctorate degree.：這個句子是正確的。「whom」指的是前面的「applicants」，而「one of whom」表示「其中一個」，句子結構和代詞使用都是正確的。

• (B) Teenagers spend an average of four hours a day on their smartphones, the majority of whom are spent on social media.：這個句子不正確。「whom」應用於指人，而這裡的「the majority of whom」錯誤地指代了「時間」，而不是「teenagers」。正確的表達應該是「the majority of which is spent on social media」來指代時間。

• (C) Over a thousand people, most of which were female, participated in the marathon.：這個句子不正確。應該使用「whom」來指代「people」，因此應該是「most of whom were female」。

• (D) On the shelf are over twenty mugs, all of which is designed by the most famous artist in town.：這個句子不正確。「mugs」是複數名詞，因此後面應該使用「all of which are designed」，而不是「all of which is designed」。

正確答案： (A) So far the manager has interviewed fifty applicants, one of whom has a doctorate degree.
