My family and I were not in danger and our house was still there. We watched the news about the earthquake. The epicenter(震中) was very close to the city near ours. We felt lucky to be in our city. The earthquake wasn't strong or serious here. After we watched the situation(情形) of that city, I decided to volunteer(自愿) to help those people at once.
I arrived in that city with a few other volunteers. We tried to help the people there. After hours of working, we found a few survivors(幸存者). We quickly sent for doctors to make sure they were all right. When they met their families, they were so happy. That made me very happy too. However, not everyone had a happy ending. We also found the bodies of those who didn't make it through the earthquake. And I felt bad when I saw the tears of those people's families. They lost their homes and familymembers.

Fire accidents often happen in our daily life. So, as middle school students, it is very important for us to learn what to do when a fire breaks out. Here are some tips, and please keep them in mind.
Put a smoke alarm in the house. Smoke from a fire causes the alarm to go off. The alarm makes a loud sound. The sound tells us to leave the house at once.
Make escape plans. We should know all the ways out of the house. If there is a fire, everyone follows the plan to get out. Part of the plan is to check all the windows to make sure they can be opened easily.
Prepare fire extinguishers (灭火器) in the house. Everyone in the family should know how to use them. Practice for a fire. We should do fire practice because it teaches us about fire safety. Everyone should know the following fire rules:
★Don’t open a hot door! The fire can grow more quickly if you open the door.
★Stay close to the floor! Smoke can be more dangerous than fire.
★The best air is near the floor because smoke rises.
★What will you do if your hair or clothes start to burn First, stop! Don’t run! The fire burns faster because of more air. Drop! Fall to the floor. Then roll! Turning over and over will make the fire go out. Put a blanket around you to keep air away from the fire that may still be on you.
There are many possible causes of fires. A wise family is ready all the time. If there is a fire, don’t forget to call 119 for help.
1.When a smoke alarm rings at a house, it means that __________.

C.run, drop and roll D.roll, drop and stop
5.What’s the main idea for the passage
A.What to do when a fire breaks out
B.How to make escape plans as quickly as possible
C.How to ask for help when a fire breaks out
D.What to do when accidents happen suddenly
二.任务型阅读
What are you going to do if you are in a burning house How will you escape Do you know how to save yourself Please read the following passage.
Escaping from a fire is a serious matter. Knowing what to do during a fire can save your life. It’s important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not elevators.
From the lower floors of the building, escaping through windows is possible. Learn the best way of leaving through windows with the least chance of serious injury.
The second-floor window is usually not very high from the ground. Of course, it is safer to jump out than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed, or smoke and fire may come into the room. Keep your head low at the window to make sure you get fresh air rather than smoke that may get into the room.
On the second or third floor, the best windows for escape are those that open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto hard ground might end in injury. Bushes and grass can help to break a fall.
根据短文内容，判断句子正(T)误(F)。
1.It’s important to know how to escape from a fire.
2.In a fire we can use elevators to come down.
3.Windows can’t be used when you are waiting for help.
4.Doors must all be open so that smoke can come into the room.
5.The passage may help save your life in a fire.
