In spring the weather becomes warm gradually. The fields are covered with green grass. The forests are filled with the songs of birds. All living things seem to be awakened from their long winter sleep. Summer is the hottest season of the year. The days are long and the nights are short. The sun often shines brightly, but sometimes there are heavy clouds and sudden storms. If it rains too much, floods might occur in some places. Autumn is the harvest time. The crops need to be gathered in and the fruits are picked in the orchards. The days get shorter and the nights become longer. The woods turn yellow and brown , leaves begin to fall from the trees. The sky is blue and people feel comfortable. When winter comes, we have to spend more time indoors because it is cold outside.
