]i have just had my watch repaired-------how much did they--

i have just had my watch repaired 前面说了我让别人把我的表修好了,后面自然会接,修表花了多少钱,所以选A,cost 有花费,花销金钱的意思B 应该是charge 吧,charge有费用的意思,但是做名词讲,动词是指充电,显明此处是要选个动词,所以不对C spend 也有花费,花销的意思,但指时间概念,特指主语是人,花销了多少时间。如:I spend a whole day to finish my homework。我花费了一整天时间来完成作业。D take 的意思很广,如果硬要扯上花费,也只能是指花费时间。用spend不同,take只能是物做主语,而不用能人。如：it take me 2 hours to finish my homework。意思与上面不变,只是主语是代语 it,而不是人综上,答案只有A打这么多字不容易啊,如果没问题就选我吧
