语法与词汇15.—The bus should take one hour and a half to get to the airport! I almost missed the flight! —______you were leaving today, I would have drove you there.
【正确答案】
C
【答案解析】句意：一乘坐公交车需要一个半小时才能到机场，我差点错过了航班。一要是我知道你今天离开，我会开车把你送到那的。此类题的做法是先写出正常语序，即if I had known you were…，倒装原则是去掉if，把had／should／were提前，C项符合题意。
