【经典考例】That famous male singer has long hair, because he long hair.
A.used to have
B.is used to having
C.is used for having
D.is used to have

【答案】B
【解析】考查used to的相关用法的辨析。used to have表示“过去常常留着,现在不留了”；is used to having表示“习惯于留着”；is used for having相当于is used to have,表示“被用来留着”。句意为：“那位著名的男歌手留着长发,因为他习惯了留长发。”故选B。
