【题目】Alice is good at singing. The underlined part means ________.
A.is good inB.does well inC.do well inD.is good for
【答案】B
【解析】
句意：Alice擅长唱歌。
考查短语辨析。A. is good in错误搭配；B. does well in在某方面干得好，does是动词的第三人称单数；C. do well in在某方面干得好，do是动词原形；D. is good for对……有好处。画线部分“is good at”意为“擅长做某事”，be动词是第三人称单数形式，与B项意思一致。故选B。
