Then, the first group filled the holes. The last group carried the water to water the young trees. At last, we totally planted five trees. We were all very delighted. Trees are helpful to our environment, which can stop the wind and protect water from losing and soil from eroding. So we should plant more trees.2. I was very happy to get your letter yesterday.
