Winter is the coldest season of the year. Winter months are December, January and February. The weather is very cold. The sun is shining but it’s not warm. It gets dark earlier and sunrise is later. The days are short and gloomy and the nights are long. Winter is a very beautiful season and many people like it very much. It usually snows in winter. So, the ground is covered with snow. The trees and the roofs are white with snow, too. The water in the rivers and lakes freezes. People start wearing warm clothes. It is such a pleasure to walk when it is not very cold and it is snowing. Winter is the ideal time for those who go in for winter sports. Many people like winter because they can go skiing, skating, playing hockey and other winter games.

Spring comes straight after long cold winter time and brings three wonderful months – March, April and May. Everybody usually is looking forward to spring because it is a very nice and beautiful season. The weather is getting warmer and warmer, everything is changing, the nature is waking up. The birds return from the hot countries and build their nests. They sing sweetly on the branches of the trees. The trees become greener. The greenery is fresh and young in the streets, in the parks and in the yards. The weather is usually fine and it is warm. Sometimes it rains but usually the sun is shining brightly.

After spring there comes summer. Oh, how people usually wait for summer to come! Spring is the most favourite part of the year for all people. This season makes everybody so happy! Shining sun makes everybody smile and laugh and look at their life positively. Summer months are June, July and August. It is warm. The sky is blue and cloudless. The days are again longer and the nights are shorter. There are many nice flowers around in the parks and squares in summer. The pupils have summer holidays so they do not go to school. People go on vacation or to the countryside. Summer is the best part of the year for the students too. In summer there is the longest day and the shortest night in the year on the 21st-22nd of June. July is the middle month of summer. It is hot and sun shines brightly. August is the last summer month some times it is cold in August, but there are many mushrooms, berries and fruits. All of us enjoy bright flowers, fruits that summer brings.

After summer comes autumn. September, October and November are autumn months. The weather is very changeable in this season. You can see yellow, red, brown leaves everywhere. It is time to gather the harvest. Sometimes autumn weather is bad. There are a lot of rainy days. So, the roads are dirty. Students and pupil begin schooling. The warm days of early autumn art called the “Golden Autumn”. The “Golden Autumn” is really beautiful with its yellow, red and brown trees and golden leaves falling down. Autumn is the season of fruit and vegetables.ПЕРЕ ВОД
