1.(2012·重庆高考)Food supplies in the floodstricken area______.We mus t act immediately before there’s none left.
A.have run out B.are running out
C.have been run out D.are being run out
解析:句意:洪灾区的食物供应将要用光了,我们必须在用完之前立即采取行动。由句中before there’s none left可知食物还没有用完,只是将要用完,故可排除表“已用完”的A项,而食物耗尽不用被动形式,故排除C、D两项;只有B项are running out表“即将耗尽”。
答案:B
