问题 It is ______ whether Sam will come to attend his best friend’s funeral as he has taken the town’s money and made off with it.

选项 A、suspicious
B、doubtful
C、dubious
D、unquestionable

答案 B

解析 近义词辨析。suspicious意为“可疑的,引起怀疑的”;doubtful意为“可疑的,令人怀疑的”,通常明确表示不肯定,如:It is doubtful whether she will be admitted to graduate school.(她能否考上研究生很值得怀疑。)dubious意为“意外的,未预料的”,表示的不确定性不那么直接和强烈,通常它含有犹豫不决、猜疑、不信任的意思;unquestionable意为“毫无疑问的”。根据句意,人们对山姆能否来持怀疑态度,故un questionable不正确;dubious语义不合适;只能在doubtful和suspicious之间选择,虽然两个词意思比较相近,但表示suspicious的只能是人,不能用于it is...的结构中。
