A．are running out; will be used up
B．are being run out; will run out
C．have run out of; will be using up
D．have run out; will run out of
答案：A
试题分析：考查词组辨析，该题可以采用排除法。词组run out和run out of都有“用完，耗尽”的意思，但是前者的主语通常为食物，时间，金钱等名词；后者表示主动含义，主语一般是人；which引导定语从句，先行词是raw materials，故排除C选项；同时that引导宾语从句，they也指代raw materials，D选项排除；B选项中，主语是raw materials，应为will be run out，B选项错误，答案为A。 考点：考查词组辨析
