分析 如果你在一个着火的房子里,你会做什么?你会怎么做来逃离这间房子?你知道如何自救吗?请阅读下面的段落.
躲避烈火是一件非常重要的事情.知道在火灾中做什么可以拯救你的生命.知道着火了要从哪条路逃出去是非常重要的,如走楼梯和防火梯等,而不能用电梯,并告诉家庭中的每个人.
从建筑物的较低楼层通过窗户逃脱是可能的,学习最佳的从窗户离开房间的方式可以减少受重伤的机会.
二楼窗户通常离地面不是很高.仅靠指尖悬挂在建筑物上的一个具有平均身高普通人,将会从六英尺高的地方跌落到地面.当然,跳过二楼的窗户要比在一个燃烧的建筑物停留更安全.
当你等待救援时窗户也是很有用的.在你等待期间,一定要保证把门关好,否则烟雾和火可能会被进入房间.把你的头低在窗口,以确保你得到新鲜空气,避免吸入进来的浓烟.
在二楼或三楼时,最好的逃生窗户是那些在屋顶处打开的窗口,从屋顶处,人可以更加安全地掉落到地面.落在水泥地上容易受伤.荒地或草地能帮助缓冲.
解答 51.B.细节理解题.根据It is important to know the ways you can use and show them to everyone in the family,such as stairways and fire escapes,but not lifts.可知,在火灾中,最重要的就是选择一条安全的逃生通道,例如走楼梯或防火梯,而不能用电梯,因此该题的答案为B.know the ways to escape the fire,知道逃离火灾的通道;
52.C.细节理解题.根据From the lower floors of the buildings,escaping through windows is possible可知,从建筑物的较低楼层通过窗户逃脱是可能的,因此如果你住在较低的楼层,你可以通过窗户逃生,即C.if you live on a lower floor;
53.D.细节理解题.根据It is important to know the ways you can use and show them to everyone in the family,such as stairways and fire escapes,but not lifts.可知,在火灾中,最重要的就是选择一条安全的逃生通道,例如走楼梯或防火梯,而不能用电梯,因此D.Use a lift to come down at once.是错误的;
54.A.细节理解题.根据Keep your head low at the window to be sure you get fresh air rather than smoke that may leaked(渗) into the room.可知,你可以从打开的窗户获得新鲜的空气,以至于不让自己吸入浓烟,因此当着火时,一定要打开窗户,目的是呼吸新鲜空气,即you can get fresh air.
55.B.文章主旨题.根据文章的描述,首段引出主题,What are you going to do if you are in a burning house?How will you escape?Do you know how to save yourself?如果你在一个着火的房子里,你会做什么?你会怎么做来逃离这间房子?你知道如何自救吗?紧接着下文开始介绍逃生方法,因此该文章的标题可以是Save Yourself in the Burning House.
