Before opening the door, feel the face of the door and the door knob for heat by using the back of your hand. If the door is cool, open the door cautiously. If the door is hot, this is an indicator that the fire is close to your room.
if the lights all go out,在这种情况下你就成了个瞎子,瞎子是怎样找东西的,那么这里的feel就是什么意思。 至于能不能换成look for,这个恐怕得问问盲人朋友。 如果有first and then,也许还有可能勉强可以理解为试试温度再开门。况且火灾致人性命的祸首往往不是高温,而是浓烟。
