　　A. Reading B. read

　　②He is well skilled playing the piano, so his music is worth . (2009·12·山东烟台模块检测)

　　A. with; listening B. with; listening to

　　C. in; listening D. in; listening to

　　解析： ①选D。 be worthy 后可以用不定式的被动语态或of being done结构，而worth后用动名词的主动语态表达被动概念。

　　②选D。be skilled in也可以用be skilled at后跟名词或动名词表示，意思是“在……方面熟练的;在……方面有能力的”。worth意思是“值得”,后跟动名词的主动语态表达被动概念。在句中，music作listen to的逻辑宾语，而listen为不及物动词，因此to不可以去掉。
