Fire was discovered many thousands of years ago. The first time humans saw fire was probably when a tree was destroyed by lightning(闪电). Humans soon learned how to make fire. They probably made the first fire by rubbing (摩擦)two sticks together.

 Fire was very important to humans. They needed to keep warm at night. They used fire to cook food. They used fire to keep enemies and wild animals away. In some parts of the world fire was used to send messages. The Indians in America, for example, used fire to make smoke as a message. In some other countries people lit fires to warn their friends of danger.

Fire was also used to give light. Before the invention of the oil lamp(灯), humans burned sticks to get light. 

One man even used fire to tell the time. He invented a candle clock. He made a candle that took exactly twelve hours to burn. Then he marked this candle in twelve equal(相等的) parts. He lit the candle and could tell the time by counting the number of parts left of the burning candle. But the candle clock did not always work well. If there was a wind blowing on the candle, it burned too quickly.

The following is a QUIZ(自测) from a magazine.

 Now teachers are beginning to worry about students' English handwriting(书写).They write carelessly and make the words or sentences ugly to look at. Is your English handwriting beautiful?

If not, here are four steps that really work!

 Use paper with lines

 Using paper that has lines can keep you writing well when you write English words or sentences. Those lines on the paper can help you to write words in the right size. Be sure to fill the lied space completely.

 Slow down

 If your writing is hard to read, try slowing down a little. For some kids, writing slowly makes handwriting clear. If you write too fast, it is hard for you to stop where you should, and even worse you may make more mistakes.

 Hold your pen right

When you hold your pen in the correct way, writing is much easier .Some students press(按压)down really hard when they write. That makes the handwriting not nice. Try to relax yourself and don't hold the pen so hard. Let your writing appear nice and clean. If you do so, people will guess you are a student with a good habit.

 Draw more pictures

 Drawing can improve your handwriting. You need to use the skills to control your pencil better when you are drawing pictures. Even though you have no chance to draw at school, you can practice by yourself at home.

    THE HISTORY OF LIVING IN SPACE

    Space travel is nothing new. The first spacecraft with a human on board blasted into space In 1961. since then, people have not only been travelling to space, but many of them have also lived there for extended periods.

Food

    All the meals on space stations are put together on Earth and sent to the space station, along with the astronauts, by space shuttle. Because the food has to last a long time (sometimes up to three months), a lot of it has to be preserved by dehydration or canning.

    The space station does not have a freezer to preserve food, but It does have a cool room to keep fruit and vegetables fresh.

Astronauts also eat many other foods such as cereals, cereal bars, nuts and dried fruit that do not need any special preparation.

    Eating

    Astronauts have a set timetable each day. This tells them when to do everything, including when to have their meals. At meal preparation time, they start getting their food ready, which often includes adding water to re-hydrate the dehydrated foods.

    Without the help of gravity, sitting down to eat can be tricky. Astronauts sometimes have to strap themselves and their food into place. Because of lack of gravity, astronauts cannot use ground salt and pepper, and all drinks must be taken from bottles. They also have to be careful that crumbs do not fly off and get stuck in vents and instrument panels.

    Many young people would like to go to west China to help children to study. One of them, Lu Yi, was a university student. One day, when she went to a small village in Guizhou, she saw the poor children herself. She felt sad. She thought she should do something for them. So she decided to stay there and to be their teacher. Money is the biggest problem for her. But she didn't give up. She worked hard and her students like her very much. After graduation(毕业), she went back to that village at once and she worked as a volunteer teacher for five years. She worked hard and her students liked her very much.
