A: Hello, my dear friends! What’s my favourite season？

B: My favourite season is spring.

A: Spring is a lovely season, I think.

B: Yes, there is a garden behind my house. In spring, the trees become green and the flowers give off fragrance.

A: There are many butterflies and bees over the flowers. The butterflies are dancing and the bees are singing.

B: Hey, guys, what are they talking about？

A: We are talking about spring.

B: Spring？ OK, I think sometimes it rains. It usually rains quietly. The rain moistens the trees and the flowers.
