有读者问《学英语》某期第2版第4题（句型转换）：
(1)It took me two days to finish reading this book. →_____ _____two days to finish reading this book.
答案是 I spent。动词 spend 这样后接不定式对吗？
一般英语词典皆规定 spend 用作及物动词时，后须接宾语（多指时间或金钱），后加“介词 on+宾语”或加“（介词 in）+动名词+宾语”，如：
(2)I spent a lot of money on books.
(3)I spent a lot of money （in）buying books.
介词 in 可省去。也可以用介词 on 代替 in, 但似乎比较少见，如：
(4)I spent a lot of money on buying books.
但似乎都没有举例说 spend 之后可接“宾语+不定式+宾语”结构。相反地，有的词书认为下面两个句子是错误的：
(5)He spent too much time to play cards.
(6)He spends his evenings to read fiction.
然而，在实际当代英语中， 我们确实看到这种“spend+宾语+不定式+宾语”结构在被使用，如：
(7)Li ...spent 800 yuan to buy 20 kilograms of caffeine and sold it to others for 4，000 yuan.
(8)The government will spend 30 million yuan to repair the rail line.
所以，在当代美语中，动词 spend 之后接不定式的用法，恐怕也不能算错。
