单选题 The book series Werewolf Mysteries is extremely popular ______ teenagers and young adults.
  • (A) throughout
  • (B) within
  • (C) towards
  • (D) among


【正确答案】 D
【答案解析】[语法] 介词among在……之中(在两者以上的个别对象中)
[错误答案] (B)within(在……之内)则要接像“within the teenage group, within the department”一样并非表示个别对象的范围。因此(B)不是正确答案。
