spen in spen on区别

spen in spen on区别

Answer 1

我想阁下您是打掉了一个字母。
spend in doing sth.（spend in 后面是接动词的ing形式，表示的是“花费……在做什么事上”）e.g. My mum always spends some time in doing housework.（我妈妈总是花费很多时间来做家务）
spend on sth.（spend on直接接名词，表示“花费……在具体的什么物上”）e.g.I spent a lot of money on birthday presents.（我花费了很多钱在生日礼物上）

Answer 2

spend in 动名词（doing）(in可以省略）
spend on + 名词

He spent two hours (in) reading English.
He spent two hours on English.
