It was extreme cold last Monday morning. While I was walking on my way to school, I noticed two street cleaner sweeping the street. Seeing them work so hard on such a cold morning, I was moved and made up my mind do something for them. After arriving at school, I discussed with some classmates that we could do. The next day, they got up early and prepared porridge (粥) at home. When we handed the cleaners with the hot porridge and expressed our appreciation for their hard work, they looked a little surprising at first. And then they takes the porridge and thanked us happily. Since it was very cold, we all fell warm at that moment.

My father took me out camping for the first time when I was seven. He wanted teach me about animals, insects and trees. My uncles all come along with bows and arrows for hunting.
One evening at sunset, we sat by the fire, have our barbecue. Just then a bird was flying over us. My uncles immediate jumped up and shot their arrows on the bird. Neither of the arrows hit the target, Suddenly the arrows was flying down at us from the sky — they were looked like rain! We ran to escape but fortunately no one was injured.
That day I didn’t learn much about animals, insects or trees, but I learnt a impressive lesson about gravity!
