Я не могу написать рассказ о лете?

Summer is my favourite season. It is very hot. The nature is beautiful. We have a long holiday. We can go for a walk all day long. We can  swim, sit down by a river or a lake on fresh, green grass and bathe in the sun. ,We can play different games. We can  ride a bicycle and rollerskate. We can go to the sea. It is wondeful! Summer is the best time of the year.
