问题
I’ll lend you my computer ______ you promise to take care of it.
选项
A、unless
B、as
C、while
D、if
答案
D
解析
本题考查连词。unless的意思是“除非,如果……不”。如:I shall go there unless it rains.(如果不下雨,我将到那里去。)as作连词使用时,意思为“当,正值”、“因为,由于”等,引导状语从句。如:As he came in,he found something unusual.(他一进来就发现有些异常现象。)while的意思是“当……的时候”。如:Please don’t talk so loud while others are working.(别人在工作的时候,请勿大声讲话。)if的意思为“如果”,因此根据题意D为正确答案。
