Everyone needs to know how to prevent a fire. It is also important to know what to do when it __1__ (break) out. Every year, over 11,000 people __2__ (kill) or injured in house fires. These fires could have been avoided. Smokers who are __3__ (care) cause about 200 deaths and over 6,000 fires. More than half of those __4__ die in fires are poisoned or harmed by smoke. If a fire happens, do not attempt to fight the fire unless it is small. Try putting out a small fire with water. If __5__ fire has spread or if the flames are more than 20 inches high, shut the door on it. Warn everyone else in the building and tell them to get out. You should leave and dial 119 for the fire department.
Before __6__ (go) into a room, check the door. If the handle or the door is hot, do not open it! Instead, put clothing or a wet towel at the bottom of it to keep smoke out. If the door is not hot, open it __7__ (slow). If there’s a rush of smoke or heat, close it again and shout to warn __8__ (other) inside. Now open the window and shout “Fire！” See whether you can drop safely to the ground. Use this __9__ your escape course if you can. If you are not on ground level, break your fall by pushing a mat out first. Lower yourself at an arm’s __10__ (long) before dropping. Once outside, stay outside and make sure the fire department is called.
语篇解读：本文是一篇说明文，主要讲了火灾的危害以及火灾发生时我们应该做的事情。 1．breaks 考查动词的时态。此处是when引导的时间状语从句，用一般现在时表将来。
2．are killed 考查动词的时态和语态。此处叙述的一般情况，且主语people与kill之间是被动关系，需用一般现在时的被动语态。
3．careless 考查形容词。根据空格后的“cause about 200 deaths and over 6,000 fires”可知空格处表示“粗心的”，故用careless。
4．who/that 考查定语从句。引导词在后面的定语从句中作主语，可用who/that引导。 5．the 考查冠词。上文第一次提到fire时用不定冠词a，第二次提到时用定冠词the。 6．going 考查非谓语动词。before是介词，其后接动名词作宾语，故用going。 7．slowly 考查副词。修饰动词open，所以用slow的副词形式。故填slowly。 8．others 考查代词。others其他的人。
9．as 考查介词。根据句意，在逃跑的过程中使用这个技能，此处as作为介词，有“作为”的意思，故填as。

10．length 考查名词。arm’s后需用名词，long的名词是length。 Ⅳ.完形填空
