炸弹爆炸使后墙的块砖都松动了。
At that point there was a huge blast and in all the smoke I managed to run back down the fire escape.就在那时候发生了一次很大的爆炸,在浓烟中我设法从防火通道中跑了下来。
Start your run into the wind and finish with it at your back, so the breeze doesn't blast you after you've broken a sweat.起跑时迎着风跑,回来时背着风跑,这样刺骨的寒风就不会在你出汗以后还肆掠地打在你身上了。
