they travel to other places, where the weather is warmer, or where they can find food.
Many birds migrate in the autumn. Some travel in large groups, because the trip can be dangerous. For example, geese (鹅) fly in noisy V-shaped groups. Other kinds of birds fly alone.
How do they know when it is time to leave for the winter? Scientists are still studying this. Many scientists think migration is part of a yearly cycle (周期) of changes that a bird goes through. The cycle is controlled by changes in the amount of daylight and the weather.
Birds can fly very long distances (距离). For example, the Arctic tern (北极雁) lives close to the North Pole (地极) in the summer. In the autumn, it flies south, all the way to the South Pole. Each spring it returns to the North Pole.
Most birds migrate shorter distances. Do you know how they find their way to the same place each year? Birds use the sun, moon and stars for direction. 76. Birds migrate to find better __________. 77. Geese travel in __________.
78. Birds know when to migrate from the __________. 79. The Arctic terns travel the __________ distance. 80. Birds use the __________ to find their way home. 八、综合填空 (本大题共10小题，每小题
