—There are ______ such books here.
—I only need ______ these books on this shelf.
A．eight dozens; one dozen
B．eight dozens of; one dozen of
C．eight dozen; one dozen
D．dozens of; one dozen of
答案
答案：D
dozen被数词或many ,several 等修饰时，不加s，后面也不用 of 。如： two / many /several dozen pencils。但如果 dozen后有 these, those, them, us等词时 dozen后要接of 。如： two dozen of us, three dozen of these eggs。故答案为D。
