单选题
I was speaking to Ann on the phone when suddenly we were ______.
【正确答案】
A
【答案解析】[解析] 本题是说我和安正在通电话,这时电话突然掉线了。A项“cut off切断,阻断,停掉;使电话中断”符合题意。如:“cut off the water supply;cut off the enemy"s retreat;be cut off from the out side world”。其他三项中,cut down“削减,减少”;cut back“削减,缩减;急忙返回”;cut out“割去,删去”,都与题意不符。所以,本题选A。
