1.slam into 猛烈撞击

He knew he would slam into him with abandon, forgetting all else.
他知道自己将不顾一切地大打出手。

Bodies slam into the boards, bare knees grind into the ground.
身体撞击着木板，膝盖碾磨着球场。

2.knock from 重打

I took a nasty knock from the thief as he ran away.
小偷逃跑时重重地打了我一下。

I used to knock about with all the lads from round where Mum lives.
我过去常同妈妈住所周围的伙伴们一起玩儿。
