Have you got any books on English grammar? I want to borrow.

Yes, here you are. But you must return it by Friday.

A. one

B. it

C. some

D. that

答案：

(答案→)A. one

B. it

C. some

D. that

解析：one泛指任何一个同名不同物的物品，it时人称代词,常常指代前文提到过的一个，some指代一些且泛指，that是指示代词,特指那个.句意：你有关于英语语法的书吗？我想借一本。——是的，给你。但是周五之前，你必须还回来。结合语境可知上文中泛指的是任何一本同名不同物的书，故选A。
