THE SEASONS AND WEATHER
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 the first 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 is a short spell of dry sunny weather in September, which is called "Indian Summer! It is a
beautiful time
when the sky is cloudless, the trees around are golden, the air is transparent and it is 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 rise late. The rivers and lakes are frozen over. Everything is covered with snow. Sometimes it is very cold,
about 25-30 °C below zero. Going out in such weather isn't 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 a fun. As for me, I like all the season, but I think there is nothing like late
spring.
