Sarah will visit Sydney in April. She asks Stella, a friend there, about the weather. Here is Stella's reply (答复).

Hi, Sarah! It is autumn in April in Sydney. Autumn is my favourite season. It is warm in the day and cool at night. Many people like the weather here. I wear my new sweater and go on a picnic on the weekends. Welcome to come and visit the Sydney Opera House. It is the most famous building in Australia. What's the weather like in Beijing? What do you often do?

All the best,

Stella
