问题补充：

―Could I use your computer for a few moments, please?

― . I’m not using it myself.

A. Come on

B. Go ahead

C. It depends

D. That’s great

答案：

A. Come on

(答案→)B. Go ahead

C. It depends

D. That’s great

解析：本题考查交际用语。由前置语境“我能不能用会儿你的电脑”以及后置语境“我自己现在不用”可知应选Go ahead.用吧！去吧！干吧！。而Come on加油；It depends.看情况而定;That’s great太棒了，均不合题意。句意：——我能使用你的电脑一会儿吗？——用吧。我自己现在不用。故B正确。
