There are four seasons in China. March, April and May make the spring. June, July and August make the summer season. September, October and November make the autumn season. The rest(剩下)of months make the winter season.
The Australia seasons are the opposite(相反的)of ours. When it's spring in China, it is autumn in Australia.
Australia is in the south(南方)of the earth. June, July and August are the winter months. The summer is in December, January and February. It's very hot there, too.
