问题补充：

—Is John coming by train.

—He should，but he not.He likes driving his car.

A. must

B. can

C. need

D. may

答案：

A. must

B. can

C. need

(答案→)D. may

解析：

come，go，leave，start等趋向动词的进行时表示将来时，所以答语是对这一将来动作做出的推断。may not“可能不，不一定”，根据he likes driving his car可以看出John可能乘火车来，也可能自己开车来。may not正好符合这一语境。must not“不准”；cannot“不可能”；need not“不必”。
