单选题 It is my deepest regret that our hotel cannot be responsible for any personal belongings left ______ even within the hotel properties.
  • (A) responsive
  • (B) unattended
  • (C) responsible
  • (D) careless


【正确答案】 B
【答案解析】left unattended意为“被置于无人照管的”。unattended就是其字面意思“无人照顾的”。D选项有干扰作用,但如果选D选项,就变成“携带的物品很粗心”,意思不通。careless应用于表示名词主体的“不小心”,比如careless behavior。
