, что можно делать только летом, только зимой, в любое время

There are four seasons in a year and each season is wonderful in its turn. But there are few things that you can do in each season. For example, in summer, you can swim in the ocean, in the pool and have sunbather. You can go for camp and for long walks. In winter, you can go to ski and skate and you can play with snow. In autumn, you can collect colorful leaves and have walks in the park. In spring, you can collect flowers and you can admire with new blossom trees. Each season is wonderful and interesting.
