When spring comes nature awakens from its long winter sleep. The days become longer and the nights become shorter. The ground is covered with emeraldgreen grass and spring flowers. The air is fresh, the sky is blue and cloudless, and the sun shines brightly. The trees are in full blossom. The nightingale begins to sing its lovely songs, and sweet melodies may be heard from every wood and park. The days are warm and everything is full of life and joy.
Spring is followed by summer. The weather is usually fine in summer, but it can be very hot, especially in July. Sometimes there are storms with thunder and lightning. In summer people try to get away from the city noise and spend more time in the open air. They pick mushrooms and berries in the forest, swim in the rivers and lakes, go fishing and boating. Most people prefer to have their holidays in summer.
Autumn begins in September. The days become shorter and the nights become longer. The leaves turn yellow, red and brown and fall to the ground. Most birds fly away to warm countries. There's a short spell of dry sunny weather in September which is called Indian Summer. It's a beautiful time when the sky is cloudless, the trees around are golden, the air is transparent and it's still warm. But gradually it gets colder and colder. It often rains in October and November which makes autumn an unpleasant season.
In winter the sun sets early and rises late. The rivers and lakes are frozen over. Everything is covered with snow. Sometimes it's very cold, about 25-30 degrees below zero. Going out in such weather isn't very pleasant. Winter is a good time for sports. People go in for skating and skiing. Tobogganing is also popular, not as a kind of sports, but rather as fun.
As for me, I like all seasons, but I think there's nothing like late spring.
