问题补充：

Jack is a great talker.It’s high time that hesomething instead of just talking.

A. will do

B. has done

C. do

D. did

答案：

A. will do

B. has done

C. do

(答案→)D. did

解析：考查虚拟语气：It’s time that从句中用should do或动词过去时，表示虚拟语气，意思是：该做…了。Time前面也可以加形容词high，about。这题填过去时did，句意：杰克是个空谈家，这是做些事而不是空谈的时候了。选D。
