问题 It would be______ to check your answers carefully before you handed in your paper.
选项 A、worth
B、worthy
C、worthwhile
D、costly
答案C
解析 同义词辨析 worth是介词，后接名词、数量词或-ing 形式，意思是“值…钱的，相当于…价值的，值得的”，worth 还可用作名词，意为“价值”；worthy 是形容词，单用作定语，意思是“有价值的，可尊敬的”，后接介词of，意思是“值得的，配得上的”；worthwhile 是个复合形容词，相当于worth one’s while，意思是“值得(做)的”；costly 意为“代价不菲的”。
