答案

1.I was born___
A.in Oct.8,1969
B.in 1969,Oct.8
C.on 1969,Oct.8
D.on Oct.8,1969
选D{时间顺序通常是“月、日,年”.因为有具体的日期,所以用on}
2.By the time I got outside,the bus___
A.leave B.left C.had alread left D.leaves
选C {公交车离开发生在got outside的过去,是过去的过去,用过去完成时.点时间只有在和for或since引导的时间状语连用时,才需考虑.比如说,如果本句是By the time I got outside,the bus___ for two minutes.时,答案只能是had been away ,而不能是had left.
