Snowfalls help to protect plants and some wild animals from snow weather.Fresh snow is made largely of air trapped among the snow crystals(晶体)．Because the air has trouble moving，the movement of heat is limited.Snow also influences the movement of sound waves.The surface of the snow takes in，or absorbs，sound waves.As snow grows older or if there have been strong winds，it can be hard and flat.Then，the snow’s surface will help to send back sound waves. Snow may be beautiful，but it can be deadly.It is responsible for the deaths of hundreds of people.Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the snow storm.Others die from heart attacks caused by too much physical activity out in the cold. People may not be able to avoid living in areas where it snows often.However，they can avoid being victims of snowstorms.People should stop driving and stay at home until the storm has passed.People living in these areas should carry emergency supplies in their vehicles.These include food，emergency medical supplies，and extra clothing to stay warm. What will the text probably tell us following the last paragraph?__________ A．How to drive during snowstorms. B．Where we can get emergency supplies. C．How to prevent heart attacks out in cold. D．Why we should stay warm in winter.
