“I his telephone number.” “I have his number, but I to bring my phone book.”
A. forget, forget
B. forgot, forgot
C. forget, forgot
D. forgot, forget

A. forget, forgetB. forgot, forgot(答案→)C. forget, forgotD. forgot, forget解析：第一个人说“我忘记他的电话号码了”，这个“忘记”应该是现在的情况，即现在忘记了，要不然就没有必要同对方说此话了，故第一空应填 forget；第二个人说“我有他的号码，但我忘记带电话本了”，这个“忘记”应该是过去的情况，即过去忘记带电话本，所以现在电话本不在身上(注意句中的转折连词 but)，故第二空应填 forgot，即答案选应C。
