Zhang Heng was a famous scientist in the history of China. His invention Hou Feng Seismometer was a great success and it helped us understand the world better.

(AD 78-139)

                      It was invented.

Zhang Heng was born in Nanyang in the eastern Han Dynasty. At that time, there were many earthquakes every year. People thought they were from ghosts. Zhang Heng, however, didn’t believe it. He tried to find ways to study earthquakes for many years and in 132 he invented the first seismometer in the world.

It was used.

But at first, people didn’t believe it and all laughed at him. In February, 138, Zhang heng’s seismometer told there was an earthquake in the west of Luoyang. After four days, three earthquakes really happened in Luoyang area. It was believed to be useful from then on. However, it was lost 1700 years ago.

It was reproduced.

Scientists have been trying to reproduce one like that. In 2012, the latest reproduced seismometer was successfully listed in Shanghai museum. It was reported to have been a little helpful during the earthquakes in Tangshan, Yunnan and Sichuan. It is hoped to be improved better soon and be able to predict coming earthquakes one day.

Waste can be seen everywhere in the school. Some students ask for more food than they can eat and others often forget to turn off the lights when they leave the classroom. They say they can afford these things. But I don’t agree with them.

    Waste can bring a lot of problems. Although China is rich in some resources(资源), we are short of(缺乏)others, for example,fresh water(淡水). It is reported that we will have no coal(煤or oil to use in 100 years. So if we go on wasting our resources,what can we use in the future and where can we move?Think about it. I think we should say no to the students who waste things every day. Everybody should stop wasting as soon as possible.

    In our everyday life,we can do many things to prevent waste from happening,for example, turn off the water taps(水龙头) when we finish washing,turn off the lights when we leave the classroom,try not to order more food than we need and so on. Little by little, everything will be changed. Waste can be stopped one day, if we do our best.
