单选题
Jimmy asked Mary to lend him some money, which she agreed to,______ that he paid her back the following month.
【正确答案】
D
【答案解析】解析:考查介词短语辨析。句意为“Jimmy向Mary借钱,她同意了,——下周还钱”。四个选项中只有on condition后面跟that从句(=if,provided that),表示“如果,只要,条件是……”,强调某人采取行动前必须事先认可的条件。on occasion“间或,有时”,in case“假使,万一”,under circumstances中间通常加形容词,表示“在……情况下”。故选D。
