有关“花费”(金钱和时间)的有4个句型: 1)It takes sb+ 一段时间+ to do sth (做某事花费某人一段时间)(一般不和金钱连用) 2) sb spend + 时间或金钱 + on sth/(in) doing sth (某人在某事/某物/做某事方面花费时间/金钱)(解释:这个句型既可以和时间连用,也可以和金钱连用。后面加on sth时意思是在某物或某事方面,接做某事方面时介词in加不加都可以) 3)sb pay +金钱+for sth.(某人花费金钱买……)(一般不和时间连用) 4)sth cost sb+金钱 (某东西花了某人……钱)(注意主语是东西,宾语是人) 我买东西要花177元: I will spend 177 yuan on it. I will spend 177 yuan (in) buying it. I will pay 177 yuan for it. It will cost me 177 yuan.
1.某人花费多长时间做某事:It takes sb. +一段时间 to do sth.(主语经常是it, 后接真正的主语不定式 )如:It often takes me an hour to finish my homework. It took him two days to solve the problem.2.某人花多少钱买某物:Sb. spend +钱的数目on sth. (主语必须是人) 某人花多少时间做某事:Sb. spend +一段时间 in doing sth. (in 可省略)Mary spent 50 dollars on the dress yesterday.They spent a week (in) finding out the truth.3. 用cost时,主语必须是物。The book cost me ten yuan.4. Pay 一般指付钱,主语必须是人。(pay for sth./ pay sb. +钱的数目 for sth.)即直接带人作宾语时,不跟介词; 带物作宾语时要跟介词for.He couldn't pay for the meal because he had little money with him.I paid the girl 20 yuan for the picture.
