There are four seasons in a year. They are spring, summer, autumn and winter. For all my friends, every season is good.

   Wang Dong likes flying kites and climbing hills. She says when spring comes, the days are getting warmer and longer. And everything begins to grow. The wind is not very strong. It’s the best time to fly kites. And when you climb the hills, you can enjoy yourself. So she often says spring is her favourite season.

   “Swimming is my favourite sport,”says Anne. “When summer comes, I often go swimming in the rivers or lakes with my friends. ”You can enjoy yourself in the water. And you can swim like a fish there.

   “I often go climbing hills with my father during the long vacation of the National Day, ”says Liu An. “My father often tells me that I can see lots of beautiful things if I stand on the top of a hill. ”So he likes autumn best of all.

   Bob says he likes winter very much. He says, “I’m very happy when I am playing with snow.”He is making a snowman now.
