三年级英语作文：Summer 夏天500字

Summer is the second season of the year. When summer comes, it is getting hot and sunny. The days are getting longer and the nights are getting shorter, for the sun gets up early and goes to bed late.

The world has become a green world, green leaves on the trees, green grass by the river, green plants in the fields, and we can see beautiful flowers everywhere. Birds sing from morning till night.

It's so hot that all of the children go swimming in rivers or lakes, and the old people sit under big trees to enjoy the cool air, but the farmers are still busy working in the fields.
