What a cold winter! How wonderful it would be if there were a fire! Fire keeps us warm. But fire is very dangerous, and can kill us. November 9 is National Fire Safety Day. It's a time for us to learn a lot more about fire, especially what to do if we are caught in a fire.
Call 119
Never try to put out a fire by yourself, even if it is a very small one. Get help from your parents or call 119. Tell 119 where you are and what is on fire. Listen to 119's instructions.
Keep down close to the floor
If there is a lot of smoke in your room, 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. If you don't, the smoke may kill you before the fire does.
Don't use the elevator
Never use the elevator(电梯) during a fire. Always use the stairs. An elevator may stop at the floor where the fire is burning. It may also go wrong and keep you inside.
Don't go back
Never go back into a burning building. Even if you have left your pet or favorite toy inside, do not go back for it. Don't worry about your pets. Animals have a very good sense of smell(嗅觉). They often get out of the building before people.

If you have a bottle of water recycled(再利用) from urine(尿), would you drink it? Astronauts at the ISS may soon do so.

NASA(美国航空航天局) said it would use a high-tech machine to recycle wastewater at the ISS. The machine will recycle water for washing hands, shower water, water for brushing teeth and even urine to make drinking water. It will save millions of dollars each year.

At present, each ISS astronaut uses about 4.4 liters(升) of water every day. It costs about 24 million dollars a year to send water up to the ISS. A liter of water costs about $ 11,000.

The machine will be sent to the ISS later. NASA hopes it will recycle about 93% of all the water used on the station.

Will the water be clean? Different chemicals will be put in the wastewater. The water will be heated to 130℃ to kill bacteria(细菌). Scientists say that the recycled water is thousands of times better than the water from a city tap.

Have you ever complained why life is so tiring? Does the sky sometimes seem dark to you? Are your studies sometimes not successful? Well, friends, cheer up and smile all the time. If you see the world with your warm heart, you will find the whole world smiles to you.

While in school, sometimes you are tired of your lessons, but have you ever noticed the happy smile on your teacher’s face when you did a good job?

One day it is fine. Just before you want to go out, it suddenly starts to rain. Maybe you would feel very sad and start complaining about the weather. But dear friends, why don’t you sit down and listen to the concert that the nature offers you? And with the timely rain, crops in the fields will grow better and better and farmers will have a good harvest.

Although everyone wants to succeed in what he tries to do, sometimes failure can’t be avoided. I think failure is not terrible, and the terrible thing is what we are afraid of it and give up hope. When we face failure, we must be confident in ourselves, draw a useful lesson from it and try our best to finish what we have decided to do. As a popular saying goes, “Failure is the mother of success.”

Attitude decided everything. With an optimistic(乐观) attitude life is easy and pleasant. Let’s smile whatever we meet and the whole world will smile to us.
