Question

Yao Ming has become a superstar in the States, but several years ago no one could have imagined the role on the basketball playground he ________.

1. A.
   has played
2. B.
   played
3. C.
   was to play
4. D.
   plays

Answer 1

C
句意：姚明已经成为了美国篮球明星，但是几年前没有人能够想象他会在篮球场上发挥如此重要的作用。时间状语several years ago提示此处指的是过去时间，故排除A和D。几年前没人能够想象将来姚明会发挥的作用，因此用was to do表示过去将来。
