Last night a strong wind as well as heavily rain struck our area. News came that the trees in the park two kilometers away from our school was blown down. This afternoon, we set off the park to do some cleaning. The head of the park met us or gave us some advice on how to clear away the falling trees, branches and leaves. Some times later, we were working hard when it begins to rain. Because few of us had taken along umbrellas or raincoats, so we were all wet. A rain lasted about an hour and it was a pity that they had to stop our work.
