You cannot imagine how exciting I was, when we had such a precious chance to do some picking on a local farm, for we had expected it for long time. The farm, what is about one hour's drive from our school, cover an area of 6 times the size of our school. We devoted the first 2 hours to collect tomatoes as well as eggplants but spent another 2 hours gathering strawberries. And at dinnertime, the food materials gathered by us becomes a wonderful meal, much to our surprise. This activity not only enriches our knowledges, but also lets us to get so close to nature. I look forward to enjoying much more similar activities in the future.
