基本结构为:
It takes + 人 + 时间/金钱 + to do something.
其中:
It 是形式主语;to do something 是真正的主语(不定式短语);takes 表示“花费”;sb 指某人;时间/金钱 是花费的内容,通常为时间(如 hours, minutes)或金钱(如 money, dollars)。该句型表示“做某事需要某人花费……(时间/金钱)”。
注意:中文习惯说“某人花时间做某事”,而英文此句型强调“做某事需要花费……”。
例句1: It takes me two hours to finish my homework.
翻译: 我完成作业需要两个小时。
例句2: It took her $50 to buy that book.
翻译: 她买那本书花了50美元。
例句3: It will take them three days to build the house.
翻译: 他们建这座房子将需要三天时间。
It 是形式主语,不能省略。take 的时态需根据上下文调整(takes / took / will take 等)。❌ 错误:It takes to finish the project.
✅ 正确:It takes us two weeks to finish the project.
❌ 错误:It took him very long time to come.
✅ 正确:It took him a very long time to come.
