　　A. Reading B. read

　　A. with; listening B. with; listening to

　　C. in; listening D. in; listening to

　　解析： ①選D。 be worthy 后可以用不定式的被動語態(tài)或of being done結構，而worth后用動名詞的主動語態(tài)表達被動概念。

　　②選D。be skilled in也可以用be skilled at后跟名詞或動名詞表示，意思是“在……方面熟練的;在……方面有能力的”。worth意思是“值得”,后跟動名詞的主動語態(tài)表達被動概念。在句中，music作listen to的邏輯賓語，而listen為不及物動詞，因此to不可以去掉。
