D解析四个选项都有“花费”的意思,spend和pay的主语都是人,其中spend常用于“sb. spends some money/time in doing sth.(其中介词in可以省略)”和“sb. spends some money/time on sth.”两种句型,表示“某人花了多少钱买某物/时间做某事”;而pay常与介词for连用;cost的主语是物,常用于Sth. costs sb. some money.句型;take常用于It takes sb. some time/money to do sth.句型,其中it为形式主语,真正的主语是动词不定式。故本题由关键词it和后面的动词不定式短语to build…可直接选出正确
