C.having been composed D.to have ever been composed
(Key:B,Why,并且翻译一下此句话,谢谢!)

吴志强专家翻译的很好，但解释值得商讨．第一：这里省略的名词Waltz不是跟在kind 后，而是在best后. of one's kind 是固定短语：属于同种类的意思．第二：名词后跟非谓语动词时，一般只有三种形式：名词+to do，名词＋doing,以及名词＋done.那使用哪种，判断方法如下：to do 表示将来，如：I have much work to do,so I will not go there with you.如果不表示将来，用doing(与名词是主动），done(与名词是被动）．这句很明显compose与waltz是被动关系．所以答案是B. 另外：名词后是不跟非谓语动词的完成形式做定语的．作定语的非谓语动词是定语从句的省略形式．当定语从句的关系代词做主语时，定语从句可省略，如果定语从句是将来时，省略成to do,如果不是过去或现在完成时，主动句变成doing,被动句变成done.完成时不可以省略，这就是名词后不跟非谓语动词完成时的原因．（如果各位见过原人民大学的许梦雄教授的著作，便知晓）．例如：1.I have three students who will go to London for further study next month.== I have three students to go to london for further study next month. 2. John is an orphan,who was broght up by his aunt.== John is an orphan, brought up by his aunt. 3. There is a bird which often sits on the line outside the house.== There is a bird often sitting on the line outside the house.
4. Gabi is my German friend, who has been to China many times.(这句不能变成 Gabi is my German friend, been to China many times.)
