Our supply of food is now . We’d better store some .
A. running out
B. running out of
C. run out
D. using up

(答案→)A. running outB. running out ofC. run outD. using up解析：短语辨析。run out of 后接物品名词，主语一般是人run out 一般以物做主语，表示该物以用光,以主动形式表示被动意义 sb. use up sth. be used up 意义与run out 相同，它本身就是被动形式，主语只能是物。根据题意，我们的食品供应用完了，主语为物，且为谓语动词的逻辑宾语。故选A。
