选择题
—Have we ________water?
—Yes, ________. We’d better get some.
A．given out; we have run it out
B．run out of, our water has run out
C．used up; our water has been run out
D．run out; our water has run out
答案
答案：B
考查短语：run out of 用完，是及物动词短语，后需要加宾语， run out被用完，不及物动词短语，无被动语态。句意：你们用完水了吗？是的，水已经被用完了，我们最好去取一些。所以选B。
