谢谢邀请。
take，spend，pay和cost四个动词都有“花费”的意思，其用法差异较大，极易混淆。但是只要掌握区分重点，就会很容易分清，下面我来结合句型和例句逐一分析:
一、taketake用来表示“做某事花去多长时间”，常见句型为: It takes/took do sth . 例如:
It takes him two hours to do the homework every night.
It took us half an hour to get to the hotel.
归纳:
take的主语往往是形式主语it，它真正的主语是后面的动词不定式，有时候take的主语也可以为路程或事情，比如:
The bus ride took me about forty minutes .
二、spend spend用来表示“花费时间或金钱做某事”，常见句型为: sb spends …on sth.和sb spends …(in) doing sth. 例如:
He spent twenty minutes on the housework.
He spent twenty minutes (in) doing the housework.
归纳:
通过上述例句我们可以看出spend的主语主要是人。
三、pay pay也用来表示“花费时间或金钱做某事”，常见句型为: sb pays/paid…for sth.，接双宾语 sb pays/paid sb…(money) 例如:
The woman paid five dollars for the lost book.
The boys paid me 20 yuan just now.
归纳:
通过上述例句我们可以看出pay的主语主要也是人。
四、cost cost主要用来表示“某物价值多少钱或某物花去某人多少钱”，常见句型为: sth cost(s) …和sth cost(s) sb…例如:
The English book cost me 25 yuan.
The magazine on the shelf costs four dollars.
归纳:
通过上述例句我们可以看出cost的主语主要是商品。
最后总结: 这四个“花费”的区分重点就在于它们各自的主语。take的主语主要是形式主语it，而spend和pay的主语是人，cost的主语是商品。
要区分主语同为人的spend和pay，我们就去看与之搭配的介词，spend主要后接介词on或者in，而pay后接介词for，例如:
Tom spent two hours on the homework .
Tom spent two hours (in) doing homework .
Tom paid five dollars for the socks.
希望我的解释能够让你满意，祝你学习进步！
spend doing和take to do的区别？
前者的主语是人，某人花费时间或者金钱做某事。
后者的主语是物，只能指花费时间。构成it takes 或者took sb st to do something。例如，
He spent a lot of money buying books.
It takes me two hours to do my homework every day.
It took them ten years to finish the invention. It will take her three hours to get there by bike next time.
另外，要表达“花钱买东西”还可以用cost, pay；
如：The jacket cost him 98 yuan. He paid 98 yuan for the jacket. He spent 98 yuan on the jacket. She spends half an hour on English in the
