Question

sb spend some time in doing sth是什么意思

Answer 1

某人花费时间做某事（in可以省略）

Spend和take的区别
简单的记住两个句型就行： It take sb. sometime to do sth. spend on /spend doing 详细解释：
Spend: spend作动词用，意思是“花费（钱、时间）；度过”。常与介词on连用，短语spend…on…表示“在某事/物上花费钱或时间”。如： He spent a lot of money on books. spend…on后面通常跟名词，若为动词，要用spend, in doing sth花费财力或时间做某事。 如：I spent half an hour in copying the text. My mother spends an hour on the housework every clay.
take当“花费”讲时，常用在句型It takes sb. some time to do sth中，它表示“花费某人一段时间做某事”。句型中的it是形式主语，不定式知语to do sth是真正的主语，take的形式随时间状语而变。如： 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. 要表达“花钱买东西”可以用lost, pay和spend；要表达“花时间做某”可以用spend和take。 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 morning. It takes her half an hour to learn English in the morning.
