We have made______a rule to practise oral English whenever and wherever______possible.?
A．it;its B．it;it C．that;it D．it;/
D
考查代詞it 的基本用法。it 可作形式主語(yǔ)和形式賓語(yǔ)，無(wú)意義，真正的主語(yǔ)和賓語(yǔ)后置。make it a rule to do...即為該用法，第二空為省略句，在時(shí)間和條件狀語(yǔ)從句中，從句的主語(yǔ)是it，謂語(yǔ)是be 動(dòng)詞，此時(shí) it is/was 可一同省略。
