There are four seasons in a year: spring, summer, autumn and winter. Every season is beautiful in its own way.
When spring comes nature awakens from its long winter sleep. The days become longer and the nights become shorter. The ground is covered with emerald green 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. 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 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. 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 is 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.
