Take和Spend有什么不同?用在那里?

spend的主语必须是人,常用于以下结构：
(1) spend time ／money on sth.在……上花费时间（金钱）.例：I spent two hours on this maths problem.这道数学题花了我两个小时.
(2) spend time ／ money (in) doing sth.花费时间（金钱）做某事.例：They spent two years (in) building this bridge.造这座桥花了他们两年时间.
(3)spend money for sth.花钱买…….例：His money was spent for books.他的钱用来买书了.
take后面常跟双宾语,常见用法有以下几种：
(1) It takes sb.＋时间＋to do sth.做某事花了某人多少时间.例：It took them three years to build this road.他们用了三年时间修完了这条路.
(2)doing sth.takes sb.＋时间,做某事花了某人多少时间.例：Repairing this car took him the whole afternoon.他花了一下午修车.
希望有所帮助
