问题补充:
If we don hurry up, everything by the time we get to the party.
A. will be eaten
B. is eaten
C. has been eaten
D. will have been eaten
答案:
A. will be eaten
B. is eaten
C. has been eaten
(答案→)D. will have been eaten
解析:D 考察时态。句义:如果我们不快点,当我们到达宴会的时候,所有的东西可能都已经被吃完了。If引导条件状语从句,从句是一般现在时,故主句要使用将来时,且由by the time可知,应该使用完成时态。故D正确。
