Step-by-step explanation:
In the Future Simple tense, the text would be rewritten as:
The long, hot days of summer will end. There won't be much sunshine during the day and the nights won't be warm. The days will grow shorter and the air will become cooler. The flowers won't bloom and the leaves won't be able to make enough chlorophyll to keep them green. Then the other colors in the leaves will begin to show. Leaves will become yellow, orange, red, and purple and later they will drop from the trees. The season of autumn will come. It will last for three months. But people won't stay at home. At weekends they will often go for walks in the parks. Children will like to stay outdoors and play football and other games. They know that winter is on its way, so they don't want to miss this wonderful time of the year - autumn.
