四季更迭：春夏秋冬，轮回而转
Every year has four seasons. They are summer, autumn, winter, and spring. The weather changes with the season. Read about each season below. Which one do you like best?
Summer is the warmest season. Fruit grows on trees. Kids play outside. Families have picnics. They have fun at the beach. In autumn, the weather turns cooler. Leaves change color and fall from the trees. Animals put food together for the winter. The coldest months are in winter. Some animals stay in a warm place to sleep. Kids play in the snow. In the spring, the weather gets warmer. Plants grow. Baby animals are born. Soon it will be summer.
As seasons change, many animals migrate. That means they move to other places. They go where there is much food and it is safe (安全的) to raise their young.
