任务型阅读（每空一词，每空1分，计10分）  It’s a good idea for families to talk about what they can do to escape(逃脱)from a fire(火灾) . Do you know what to do if there is a fire in your flat? Here are some tips for you: 1. Shout out. Shout as loudly as you can, because people may be asleep. 2. Call 119. Never try to put out a fire yourself. Tell 119 where you are and what is on fire. 3. Keep down close to the floor. There is less smoke down there, so it’s easier to breathe (呼吸) and see where you are going. 4. Test the door. If the door is cool, open it carefully. If not, do not open it! Try to find a different way out. 5. Get out. Do not stop to pick up anything. A fire can become very big in a few seconds! 6. Don’t use the lift（电梯）. Always use the stairs (楼梯) . The lift may go wrong. It isn’t safe and many keep you inside in a fire. 7. Don’t go back. Even if you leave your pet or favorite toy inside, do not go back for it. Animals have a very good sense of smell. They often get out of buildings before people. 小题1: to do in a fire
