问题补充：

Our English teacher is for England July 29th.

A. leaving, in

B. leaving, on

C. going to leave, at

D. going to leave, in

答案：

A. leaving, in

(答案→)B. leaving, on

C. going to leave, at

D. going to leave, in

解析：根据is可知后面应该跟doing，但四个选项都是doing，且都与is构成将来时，所以只能根据第二个空选择；因为7月29日是具体的一天，所以应该用on。所以本题选B。
