If you have no tools or heavy objects to break the window with, use your feet. If you have high heels, these might work when placed at the center of the window. Be aware that it's very hard to break a window by kicking, so find these breakpoints.
如果你没有工具或坚硬的东西来打破窗户，那就用你的脚。如果你穿着高跟鞋，对着窗户中间猛踢也许会有用。记住仅仅敲击窗户是很难打破的，试着去找突破点。
If you have a heavy object, aim for the center of the window. A rock, hammer, steering wheel lock, umbrella, screwdriver, laptop, large camera, etc., might all serve as suitable battering objects. Even the keys might work if you're strong enough.
如果你有坚硬的东西，就直接打窗户的中心。石头、锤头、方向盘锁、伞，螺丝起子、笔记本、大型照相机等等，都可以作为合适的敲打工具。如果你的力量够大，钥匙都可能帮上忙。
