问题补充：

— Why did you stop writing, Tom?— My ink has .

A. used up

B. run out

C. run out of

D. been run out

答案：

A. used up

(答案→)B. run out

C. run out of

D. been run out

解析：考察动词短语辨析。A用完（有被动语态）；B用完（不能用于被动语态）；C用完（后面要接宾语）；句意：—Tom，你为什么不写了？—我的墨水用完了。如果选AC项，要使用被动语态的修饰。Run out用完，耗尽；是没有被动语态的形式的。故B正确。
