【简答题】
When people want to know about the weather, they usually go to their radios, TVs, newspapers, or to the Internet. However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around. Deer leave high ground and come down from the mountains. Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable(暴躁) and quarrelsome and will fight over a piece of bread. Other birds chirp and sing just before a storm. It seems they know they won’t get another chance for an hour or two. Birds also look for safe places before a storm. You will sometimes see birds settling in trees or gathering together on a wire close to a building. Pre-storm low pressure make the air so thin that birds have difficulty flying. It is unusual to see many birds flying overhead in the summertime, rather than during the periods in the spring or autumn. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying ahead of a storm. By paying closer attention to some important signs in nature, we can become better prepared for any kind of weather. 小题1:The word “indicators” in paragraph 1 probably means .
