Four seasons

A year is divided into four seasons. As the seasons change, so do temperature, weather and the length of day. At the end of the year, people usually send “season’s greetings” to their family members, relatives or friends by posting them Christmas cards. 
“Season” also means a period of time marked by a certain activity or a large quantity of a certain product, for example, the rainy season, the strawberry season or, for football fans, the football season. 
Fruits are the best and cheapest in the season. But hotels cost more in the season. That is why some people take their holidays out of season.
