More and more people have realized that we won’t have cleaner water to drink unless something _______soon.
A．is doneB．was doneC．will be done D．to be done
A

試題分析：句意：越來越多的人意識到如果我們不馬上采取措施我們就不會有干凈的飲用水。在unless 引導(dǎo)的從句中，something 是主語，它與謂語動詞do 構(gòu)成被動的關(guān)系，所以這里要使用被動語態(tài)。而且unless 從句中應(yīng)用一般現(xiàn)在時，故選A。
