Speaker A: I'd like to buy the refrigerator, but I'm one hundred dollars short.

Speaker B: __________if you promise to give it back before this weekend.

A. I'll borrow you the money

B. I'll lend you the money

C. I'd lend you the money

D. I will have lent you the money

B【解析】說(shuō)話者A說(shuō)/她想買那臺(tái)冰箱，但是還缺l00美元。說(shuō)話者B說(shuō)如果說(shuō)話者A能在周末前把錢還給他/她，就同意借錢給他/她。四個(gè)選項(xiàng)中，A項(xiàng)動(dòng)詞borrow表示“借入”，不合題意，C項(xiàng)語(yǔ)氣錯(cuò)誤，D項(xiàng)時(shí)態(tài)錯(cuò)誤。因此，B項(xiàng)為正確答案。
