Hi @YuQinCai, @Constance_Fang @Fiona and the ChinesePod team, my question is this:
I found some interesting things when learning these phrases.
问路 -------- 问一下路
看电视 ------- 看一下电视
吃饭 ------- 吃一下饭 (wrong)
打球 ------- 打一下球
看书 ------ 看一会书
Just out of curiosity, what potential rules shall we use to decide which phrases can be transformed to this kind of structure? Thanks. Happy to discuss.
