A. doesn’t rain B. won’t rain C. doesn’t rain D. isn’t raining

【答案】C

Hollow bones also help in flying because they help make the bird light enough to fly.

Some birds feed on plants, some birds eat insects. and still others eat other, animals like fish, snakes, mice or rats. Birds are also known for their migrating（遷徙）patterns to large groups.
