阅读理解：

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 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 seek 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 makes 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.1.

By noticing the movements of other animals.解析：C正确。鸟是如何感知暴风雨将要来临？文章的对应处：Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways.3. The best title for the text would be .A. Signs of a StormB. Drops in Air PressureC. Animals’ Sharp SensesD. Nature’s Weather Signs解析：D正确 文章的最佳标题是哪个？可以找到文章的主旨句：you can also find many weather signs among wildlife, because of their highly developed senses.以及最后一段的总结句可以判断得出。参考译文：通常人们通过广播，电视，报纸或者是网络来了解天气情况。不过你也可以通过野生鸟兽发现许多天气迹象，因为它们有高度发达的感觉能力。空气压力下降会对小动物产生各种各样的影响。老鼠和鹿就是很好的天气指示者。人们长时间的户外观察发现，在暴风雨前田鼠会从洞里跑出来，四处窜。鹿会离开高地，从山上跑下来。鸟类尤其是很好的天气预报员，它们也用很多方式表现出压力下降产生的影响。例如，一些鸟变得很急躁，吵吵闹闹的，为了一片面包打架。一些鸟在暴风雨来临前叽叽喳喳地鸣叫。就好像它们知道一个小时或两个小时后就会有风雨降临。鸟也会在暴风雨前寻找安全的地方。你有时会看见鸟在树上搭窝或是在建筑物边上的电线上聚集。这是由于暴风雨前的低压使得空气变得很稀薄，造成鸟飞行困难。不像在春秋季，在夏天时节，看到许多鸟在天空飞是很不寻常的。如果你看到这个景象就看看别的信号。如果它们飞往错误的方向，它们有可能是在暴风雨来临前飞行。通过仔细观察自然界中的各种重要信号，我们可以更好地为各种天气做准备。词汇及短语：indicator: 指示器, 记录器; 指示物; 指示者irritable: 易怒的, 急躁的quarrelsome: 喜欢吵架的,好争论的 chirp: vi.鸟叫; 虫鸣overhead: adv. 在头顶上; 在空中
