B
Sometimes, we can discover human history in surprising places. Not long ago, scientists in Spain found over 200 human-made items in ancient bearded vulture nests(巢穴). Surprisingly, the oldest item is about 700 years old. This discovery shows how nature can preserve(保存) human history in unexpected ways.
Bearded vultures are large birds and usually live in areas with mountains. Although they eat small animals, their main(主要的) food is animal bones(骨头). They break bones into smaller pieces by dropping them from great heights. These birds used to be common in southern Spain. But because of hunting and modern farming practices, no bearded vultures live in the area now.
The nests of bearded vultures are special because the birds have a habit of using them over and over again. Scientists searched for these old nests. To find them, they studied many historical records to learn where the birds once lived in the area. Finally, they found 12 ancient nests built long ago. Once they discovered the nests, they studied everything inside. As expected, they found lots of bones. However, to the scientists' great surprise, there were quite a lot of human-made things. The birds probably brought the items back to build their nests.
This discovery makes protecting bearded vultures even more important. Today, there are only a few thousand left in the wild. Scientists are working hard to help their number grow.

C
It’s easy to think “that will never happen to me”, but natural disasters are becoming both more common and more serious. Millions of families face floods, tornadoes and other natural disasters every year. In Australia, for example, its wildfires from 2019 to 2020 were caused by the high temperature and drought(久旱). They took away the lives of hundreds of people and billions of animals!
While you can’t stop disasters from happening, you can stay safe during one if you know what to do.

Floods
Floods can happen very suddenly. Flood water can be deeper than it looks. It can carry you away, so stay away! Glass, snakes and dirty things can be in flood water, so don’t drink it even if you are thirsty.
Tornadoes
A tornado happens during some storms. If there’s a tornado warning, go someplace, such as a small and sturdy (结实的) bathroom which is safe from the wind and flying things. Remember to keep away from windows and anything heavy that might fall on you.
Earthquakes
You should move away from things that might fall. Get down under something that’s strong if you can’t rush out of the building right away. Protect your neck and head with your arms. If you’re outside, go to an open space. Stay away from trees or anything that might fall over and hurt you.
Bush fires
Bush fires, also known as wildfires, are common across the world during the scorching days. It is important that you try to stay calm. Some fires can start so quickly that they threaten(威胁) homes and lives within minutes, so your safest choice is always to leave early.

A. wildfires are far away from us
B. Australians are now in great danger
C. the high temperature and drought cause wildfires

这是一篇关于自然灾害的英语阅读理解题，包含3道小题，分别考查推理判断、词义猜测和主旨大意。解题思路如下：
1. 第53题：需明确作者举例的目的，先定位原文第一段，作者先提出“自然灾害正变得更常见且更严重”的核心观点，再举澳大利亚野火的例子，目的是支撑该观点，需区分举例目的与例子的原因。
2. 第54题：词义猜测题，需结合上下文语境，scorching修饰野火发生的日子，前文提到野火由高温干旱引起，因此该词应表示“炎热的”，需结合逻辑关联判断词义。
3. 第55题：主旨大意题，需梳理全文结构，文章先引入灾害话题，再分四类灾害讲解在灾害中保持安全的方法，需提炼核心内容而非片面信息。
【解析】
53题：根据原文第一段“It’s easy to think... but natural disasters are becoming both more common and more serious. In Australia... wildfires... took away... lives...”，作者举澳大利亚野火的例子是为了支撑“自然灾害正变得更常见且更严重”的观点。A选项与原文观点相反，B选项偏离举例目的，C选项是野火发生的原因而非举例目的，故选D。
54题：根据前文“its wildfires from 2019 to 2020 were caused by the high temperature and drought”及“Bush fires... during the scorching days”，野火发生在炎热的日子，scorching意为“炎热的”，对应选项C（Hot），A（暴风雨的）、B（下雨的）、D（寒冷的）均不符合语境，故选C。
55题：全文围绕“虽然无法阻止自然灾害发生，但可以在灾害中保持安全”展开，分述了洪水、龙卷风、地震、丛林火灾的安全应对措施。A选项（灾害为何发生）、C选项（灾害带来的影响）、D选项（灾害的命名）均未涵盖核心内容，B选项（如何在自然灾害中保持安全）符合主旨，故选B。
【答案】53.D 54.C 55.B
【知识点】英语阅读理解；推理判断；词义猜测；主旨大意
【点评】本题为八年级英语上册阅读理解常规题型，考查学生对文章细节、逻辑关系及主旨的把握，需结合上下文分析举例目的、词义及核心内容，难度适中，是学生应掌握的基础题型。
