21、請以“The Seasons”為題，有條理地用英語介紹一下四季給你的印象和感受。

　　Four Seasons

　　There are four seasons in a year. They are spring，summer，fall and winter. I like spring. It is warm. It often rains. I can plant trees and flowers in spring. The spring is green. Summer is very hot. I can swim in the river. Fall is a good season. It is nice. I can fly kites in fall. I can eat many apples，too. Winter is cold. I wish I can play with snow and make a snowman in Heyuan. Because it doesn’t snow in our city.

　　I love all the seasons, because they are nice.

　　四季

　　一年有四個季節。它們是春天，夏天，秋天和冬天。我喜歡春天。春天很暖和。春天經常下雨。春天我可以種樹和種花 。春天是綠色的。夏天很熱。我可以在河里游泳。秋天是一個很好的季節。它很美。我可以在秋天放風箏。還可以吃很多蘋果。冬天很冷。我希望我可以在河源玩雪和堆雪人，因為我們的城市不下雪。

　　我愛所有的季節，因為它們都會美。
