---WouldyoumindifIusedyourbike?---____.A.OfcourseB.GoaheadC.GoodluckD.

--- Would you mind if I used your bike? --- ____.A.Of courseB.Go aheadC.Good luckD.Good idea

B解析试题分析：句意：--如果我用你的自行车你介意吗？--可以，用吧。Of course当然，这是说不让用。Go ahead 用吧；Good luck祝你好运；Good idea好主意。考点：考查交际用语的用法。点评：本题难度适中。交际用语的考查要放在上下文语境中理解运用，提醒考生平时加强背诵短语的意义及用法。即学即练：—Do you think you could do without help? —______. This is not the first time for me. A. Take care B. Hurry up C. Not exactly D. Don’t worry解析：D。根据后置语境This is not the first time for me可知，答语应表示“没问题，别担心”之意，所以D项符合语境。
