问题补充：

—Ann is in hospital.

—Oh，really？I know.I go and visit her.

A. didn ；am going to

B. don ；would

C. don ；will

D. didn ；will

答案：

A. didn ；am going to

B. don ；would

C. don ；will

(答案→)D. didn ；will

解析：第一空的“不知道”应该是过去不知道，现在已经知道了，因此要用一般过去时，答案在A、D两项中产生。be going to和will都可以表示将来要发生的动作，be going to往往表示计划和打算，而will则表示临时作出的决定，因此第二空应用will。
