fire extinguisher
We should all have at least one fire extinguisher in our house or school. However, it’s not enough to simply keep one somewhere. The best way to be ready for a fire is to study this guide carefully and review it regularly.
Have a clear way out
Before using the fire extinguisher, make sure you have a clear way out. If you cannot put out the fire, you will need to find a safe way out.
Call the fire department
Even if you can control the fire, you should always have the fire department on the way. Once firefighters arrive, they can double-check if the fire has been completely put out.
Stand back
Face the fire and keep your back to the clear exit. You should stay between 1.8 and 2.5 metres away from the flames(火焰) as you prepare to use the fire extinguisher.
Use the extinguisher
It can be difficult to think clearly in a fire. One method to help you remember how to operate an extinguisher is to remember “PASS”.
• P—Pull: Pull the pin(保险销) on the fire extinguisher.
• A—Aim: Aim low. Point to the bottom of the fire instead of the flames.
• S—Squeeze: Squeeze the handle(把手) to set out the extinguishing chemicals.
• S—Sweep: Sweep the nozzle(喷嘴) from side to side until the fire is put out.
Keep an eye on things
After the fire appears to be out, continue to watch the fire area to make sure it doesn’t start burning again. If the fire does start up again, repeat the “PASS” process.
Get to a safe place
Once the fire is out, or if you are unable to put it out, leave at once. Find a place out of reach of the fire.
() 4. What can firefighters make sure even if the fire seems controllable?

() 5. Which is the CORRECT order to show the steps of “PASS”?

() 6. Why does the writer write the passage?
A. To show us how to stay away from a fire.
B. To teach us how to use a fire extinguisher.
C. To share his experience of putting out a fire.
D. To tell us what to do when there is a fire emergency.

答案：4. C 5. B 6. D
解析：
4. 定位到文中"Call the fire department"部分的内容"Once firefighters arrive, they can double-check if the fire has been completely put out."，可知即便火势看起来可控，消防员也可以确认火是否被完全扑灭，对应C选项。
5. 根据文中"PASS"的操作步骤：第一步P-Pull拔出灭火器保险销，对应图④；第二步A-Aim瞄准火焰底部，对应图③；第三步S-Squeeze挤压把手喷出灭火药剂，对应图①；第四步S-Sweep左右摆动喷嘴扫射直到火被扑灭，对应图②，正确顺序为④③①②，对应B选项。
6. 通读全文可知，文章不仅介绍了灭火器的使用方法，还涵盖了火灾突发时确认逃生通道、拨打消防电话、保持安全距离、灭火后留意火情、及时撤离到安全区域等全套应对做法，A选项仅讲远离火灾、B选项仅说教用灭火器都过于片面，C选项文中没有提及作者的个人灭火经历，因此本文目的是告诉我们发生火灾紧急情况时该做什么，对应D选项。
