people, especially children and seniors, even found it difficult to breathe. As a result, local hospitals were crowded with people who had problems with their noses and lungs.

Part of the cause was the dry weather, but the severely damaged environment contributed a lot to this nightmare. Personally I didn’t get any health problems in the haze because I stayed mostly indoors. But to make a significant change we really have to do more to protect our environment. To live a better life we have to push on with the economy, but it would be meaningless if we have to achieve it at the cost of our breathing air.

Yours sincerely,

In order to help the earthquake victims to go through the hard time and rebuild their hometown, the school has called on everyone in our school, including both teachers and students, to donate money to the earthquake-stricken area.

This donation is voluntary. You can give away however much you want to. The money will be collected by each class before it is handed to the Red Cross Society of our school. We hope that everyone will be kind enough to do what you can to help our fellowmen（同胞） out of the difficulty.
