spend,take,cost作花费讲时,有什莫区别?take可以指花钱吗?

spend,cost,take,pay 都可以表示“花费”,但用法却不尽相同.
1)spend的主语必须是人,常用于以下结构：
spend time/money on sth.在……上花费时间(金钱).
如：I spent two hours on this maths problem.这道数学题花了我两个小时.
spend time/money (in) doing sth.花费时间(金钱)做某事.
如：They spent two years (in) building this bridge.造这座桥花了他们两年时间.
spend money for sth.花钱买…….
如：His money was spent for books.他的钱用来买书了.
2)cost的主语是物或某种活动,还可以表示“值”,常见用法如下：
sth.costs (sb.)+金钱,某物花了(某人)多少钱.
如：A new computer costs a lot of money.买一台新电脑要花一大笔钱.
(doing) sth.costs (sb.)+时间,某物(做某事)花了(某人)多少时间.
如：Remembering these new words cost him a lot of time.他花了大量时间才记住了这些单词.
3)take后面常跟双宾语,常见用法有以下几种：
It takes sb.+时间+to do sth.做某事花了某人多少时间.
如：It took them three years to build this road.他们用了三年时间修完了这条路.
doing sth.takes sb.+时间,做某事花了某人多少时间.
如：Repairing this car took him the whole afternoon.他花了一下午修车.
take 后一般加时间或是精力,很少加钱.
