有一读者问： 下面几个句子中哪个是错误的：
(1)My sister paid 200 yuan for a new bike.
(2)My sister spent 200 yuan on a new bike.
(3)A new bike cost my sister 200 yuan.
(4)It took my sister 200 yuan to buy a new bike.
我认为上述句（4）也不错，因为我见过：
(5)It takes a lot of money to buy a house as big as that.
不知你以为如何？
上述句（1）、（2）、（3）无争议，都对。句（5）也不算错，虽然似乎尚未得到公认；句（4）也许有人这样说，但欠严谨。
