问题 I hope the plan will work, but they themselves are very ______that it will.

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

答案 A

解析 近义词辨析。四个选项均含有“怀疑,不确定”之意。doubtful 意为“怀疑的,不确定的”,表示对于某事怀疑、犹豫不决,如:feel doubtful about whether to go or not (拿不定主意去不去);suspicious 意为“表示怀疑的,有疑心的”,如:I’m very suspicious about her motives.(我对她的动机甚为怀疑。) suspect 意为“不可信的,可疑的”,语气较为肯定,如:His statements are suspect.(他的说法靠不住。)dubious 意为“半信半疑的”,所表示的不确定性不那么直接或强烈,通常含有犹豫不决、猜疑、不信任的意思,如:a dubious distinction (令人怀疑的差别)。根据句意以及上述解析可知,本题应选A)。
