1.社会实践运动At my school, we have held a lot of social practice activities. Last month, I went to the Science and Technology Museum with my classmates.The Science and Technology Museum is a wonderful place for young people to leam. I visited the natural world and found something new. It was amazing. Besides, I did a lot of experiments in physics by myself. They helped me to put what I had learned into practice. I saw a lot of interesting things in the museum. too. I learned a lot.I was pretty excited and happy at that time. In my opinion it is a good way for us to learn something useful out of the books in museums.2.献爱心捐赠At my school, We had a charity sale last week.The charity sale was held on our school playground last Saturday morning. We prepared many things which were made by hand in our spare time, such as kites, model planes and so they looked very beautiful. We also brought secondhand books to sell on the sale. In the end, the money we made added up to over 2.000 yuan. We sent the money to thecommunity to help children who suffered from the flood.I'm proud of what we have done. If everyone makes a contribution to the charity, the world will become much better.
