A.waiting B.waited C.to wait D.wait
答
选A.根本不是独立主格.
how many more pieces by the master lie waiting to be discovered是who knows的宾语从句.从句中how many more pieces by the master 是主语,lie是谓语动词,waiting to be discovered作状语,也有人认为是主补之类.wait和 how many more pieces是主谓关系,所以用现在分词,discover和 how many more pieces为动宾关系所以后面用to be discovered.
