I was wearing a seatbelt．If I hadn’t been wearing one，I ____．（ ）
A. were injured
B. would be injured
C. had been injured
D. would have been injured
该句“I was wearing a seatbelt．”使用了过去进行时，表示过去的事实状况，意为：当时我正系着安全带；if从句中使用了过去完成时，表达了与过去事实相反的情况，即“如果我没系上安全带的话”；通过以上分析可知：本句是虚拟条件句，由于从句使用了过去完成时，那么主句就应该使用would have done的形式，这里injured是形容词；故选D
