Food supplies in the flood-stricken area ______. We must act immediately before there’s none left.
A．have run outB．a(chǎn)re running out
C．have been run outD．a(chǎn)re being run out
B

試題分析：句意，在發(fā)生洪水的災(zāi)區(qū)食品供應(yīng)即將用完。我們必須在全部用完之前采取行動。run out為不及物動詞短語，不能使用被動形式，由此可排除C和D兩個選項。A選項為現(xiàn)在完成時，原題中想要表達(dá)將要用完，還沒有用完，所以不合題意，B選項為現(xiàn)在進(jìn)行時態(tài)，可以表示將來，符合題意，故選B。
點評：解答這類題時要理解題干意思，準(zhǔn)確判斷出時態(tài)。另外根據(jù)詞組本身排除某些選項。一般來說，只有及物動詞（詞組）才有被動語態(tài)。
