问题描述:

We spend half an hour ( ) (piay)football every day 怎么填

in playing
spend...in doing sth.

spend sb sometime on sth
spend sb sometime( In)doing sth
故填playing,省略in

playing

in playing
spend in doing sth 固定词组:花费时间做什么事

(in) playing (spend...(in) doing...:表示“花费时间/金钱做某事”,其中的介词in常省略,后加动词-ing形式.)

(in)playing 其中in可以省略,这是个固定搭配 记住spend in doing sth 其中in可以省略就可以了
