题目

 Our food supply _______. We’d better get some in case there’s _______ left. A. is running out; none                        B. has run out of; none C. is using up; nothing                        D. has used up; nothing 答案：解析：选A。第一空表示快用完不是已用完，故使用进行时表示将来；第二空特定指食物，故使用none。 独具【举一反三】 Her money has been _______ and her patience is also _______ . A. run out; run out B. run out of; run out C. run out of; running out of D. run out of; running out 解析：选D。run out of sth. “用完某物”；run out是不及物动词短语。题干中第一空前面用了被动语态，意味着后面要接及物动词短语，即run out of。第二空用进行时表示将来意味，即“快耗尽了”。
