He asked me to lend him some money, which I agreed to do, __________ that he paid me back the following week.

A.on occasion 
B.on purpose 
C.on condition 
D.only if

参考答案

C

答案解析

【译文】他向我借钱,我同意了,但条件是下周还钱。
【解析】词组的含义和用法。四个选项中只有C.on condition后面跟that从句,是正确答案,表示“在……条件下,如果,倘若”。on occasion表示“间或,有时”;on purpose“故意”;only if“只要,只有”,用于句首时,后面主句的主谓语要倒装.如:Only if a teacher has given permission is a student allowed to enter this room.
(只有得到老师的允许,学生才可以进这屋。)
