【题目】Dear Lin Tao,

How are you? Right now I'm watching the weather report on TV. It says it will snow in Beijing. But it's summer in Australia now! Our summer is in December, January and February. It's really hot now. I like summer because my favorite sports are swimming, beach volleyball and surfing.

Our autumn is from March to May. Some trees turn yellow and orange, but many trees are green all year. The weather is warm and sunny. We often go to the Blue Mountains to enjoy the fresh air!

Winter in Sydney starts in June and ends in August. The weather is not very cold. It never snows, but it rains a lot. Helen and I like to watch football games, even in the rain. Sometimes we go to a beach and watch whales swimming in the sea.

Spring here is from September to November, I like spring best. The weather gets warmer and everything begins to grow. Trees turn green and flowers come out. My family often has a barbecue at a park or on a beach.

What about the seasons in Beijing? I know they are really different! What do you usually do in different seasons?

Please write back soon!

Best wishes.

David
