Some ancient people believed that lightning and thunder were the weapons of the gods. In reality, lightning is a flow of electricity formed high above the earth. A single flash of lightning has 1.6 kilometers long, and has enough electricity to light one million light bulbs (灯泡). The American scientist and statesman, Benjamin Franklin, was the first to show the connection between electricity and lightning in 1752. In the same year, he also built the first lightning rod (避雷针). This device (装置物) protects buildings from being damaged by lightning. Modern science has discovered that one stroke (闪击) of lightning has a voltage (电压) of more than 15 million volts (伏特). A flash of lightning between a cloud and the earth may be as long as 13 kilometers and travels at a speed of 30 million meters per second. Scientists judge that there are about 2 000 million flashes of lightning per year. Lightning hits the Empire State Building in New York City 30 to 48 times a year. In the United States alone it kills an average (平均数) of one person every day. The safest place to stay in case of an electrical storm is a closed car. Outside, one should go to the low ground and not get under the trees. Also, one should stay out of the water and away from the metal fences. Inside the house, people should avoid opening doorways and windows and not touching wires or metal things. With lightning, it is better to be safe than sorry. 26．People thought lightning came from ________ in the past. A．the sky B．the gods C．the Earth D．the nature 27．According to the passage, what do all the buildings need? A．Metal fences. B．Electricity. C．Lightning rods. D．Machines. 28．Lightning can travel ________. A．as quickly as water B．not so quickly as electricity C．at a low speed D．at a high speed 29．Which of the following is NOT true? A．In the U.S., about one person dies from lightning per day. B．The Empire State Building frequently gets hit by lightning. C．Swimming during a thunderstorm is a good idea. D．A closed car is the best place to protect yourself during an electrical storm. 30．Lightning is sometimes ________ to human beings. A．harmful B．kind C．useless D．friendly 【答案】26．B 27．C 28．D 29．C 30．A 【导语】本文是一篇说明文。主要介绍了闪电的相关知识，包括古代人们对闪电的认知、闪电的科学本质、相关科学发现以及雷暴天气中的安全防护措施等。 26．细节理解题。 根据第一段“Some ancient people believed that lightning and thunder were the weapons of the gods. (一些古代人认为雷电是神的武器。)”可知，过去人们认为闪电来自神。故选B。 27．细节理解题。根据第二段“In the same year, he also built the first lightning rod. This device protects buildings from being damaged by lightning. (同年，他还制造出了第一根避雷针。这种装置能保护建筑物免受闪电的破坏。)”可知，避雷针能保护建筑物免受闪电损坏，由此可指，建筑物需要避雷针。故选C。 28．细节理解题。根据第三段“A flash of lightning between a cloud and the earth may be as long as 13 kilometers and travels at a speed of 30 million meters per second. (一朵云与地球之间的一道闪电可能长达13千米，其传播速度为每秒3000万米。)”可知，闪电的传播速度很快。故选D。 29．细节理解题。根据最后一段“Also, one should stay out of the water and away from the metal fences. (此外，人们应该远离水域，并且不要靠近金属围栏。)”可知，雷暴期间不应待在水里，游泳并非好主意。故选C。 30．推理判断题。根据第四段“ In the United States alone it kills an average (平均数) of one person every day. (仅在美国，闪电平均每天就会夺走一人的生命。)”可知，闪电有时对人类是有害的。故选A。 B Have you ever heard of an avalanche (雪崩)? The avalanches are a kind of sudden natural disaster like earthquakes. During an avalanche a lot of snow and ice rush down the mountain. As they rush, the snow and ice move faster and faster. In fact, snow from an avalanche can move as fast as two hundred miles an hour. That is three times faster than a car on a highway! Most avalanches happen after big storms. In the mountains like the Alps and the Himalayas, there is snow and ice all year round. After big storms, new snow puts more pressure (压力) on the snow that is already in the mountains. It can make the old snow rush down. Avalanches are very dangerous. Heavy snow moving down the mountains may pull trees and rocks along. That can cause great damage, such as pushing down houses and killing people. Luckily, no one lives in the mountains where avalanches are easy to happen. So not many people die from avalanches each year. Most people who may lose their lives in avalanches are ski (滑雪) lovers. It's important for them to stay safe while having fun in the snowy mountains. Scientists can usually tell whether an avalanche might happen or not. If you are a ski lover, remember to pay attention to scientists' warnings before you go skiing. 31．Which word best describes the avalanche according to Paragraph 1? A．Sudden. B．Fast. C．Powerful. D．Dangerous. 32．What makes the old snow rush down the mountain? A．The pressure. B．The mountain. C．The storm. D．The ice. 33．What does the underlined word “damage” probably mean in Chinese? A．噩耗 B．扫荡 C．赔偿 D．破坏 34．What should ski lovers do before skiing according to the passage? A．Go and talk to scientists about avalanches. B．Learn about how to keep themselves safe. C．Check whether there is an avalanche warning. D．Live far away from the mountain with avalanches. 35．The writer wrote the passage mainly to . A．teach people to stay alive from avalanches B．warn people of the possible avalanches C．introduce a natural disaster D．ask more people to go skiing 【答案】31．B 32．A 33．D 34．C 35．C 【导语】本文是一篇说明文。本文主要介绍了雪崩这一自然灾害。包括雪崩的特点、发生的原因、危害，还特别提到了容易在雪崩中遭遇危险的滑雪爱好者以及他们在滑雪前应注意科学家的警告以确保安全。 31．细节理解题。根据第一段“In fact, snow from an avalanche can move as fast as two hundred miles an hour. That is three times faster than a car on a highway! (事实上，雪崩中的积雪能以每小时200英里的速度移动。这比高速公路上的汽车还要快三倍！)”可知，文中重点强调了雪崩时雪移动的速度非常快。故选B。 32．细节理解题。根据第二段“After big storms, new snow puts more pressure (压力) on the snow that is already in the mountains. It can make the old snow rush down. (大风暴过后，新下的雪会给山上原有的积雪施加更多的压力。这会使原来的雪冲下来。)”可知，是新雪带来的压力使得旧雪冲下山。故选A。 33．词句猜测题。根据第三段“Heavy snow moving down the mountains may pull trees and rocks along. That can cause great damage, such as pushing down houses and killing people. (从山上下来的大雪可能会裹挟着树木和岩石。这可能会造成巨大的损害，比如推倒房屋和致人死亡。)”可知，从“推倒房屋和致人死亡”这些后果可以推断出“damage”的意思是“破坏”。故选D。 34．细节理解题。根据最后一段“If you are a ski lover, remember to pay attention to scientists’ warnings before you go skiing. (如果你是一个滑雪爱好者，记得在你去滑雪之前要留意科学家们的警告。)”可知，滑雪爱好者在滑雪前应该查看是否有雪崩预警。故选C。 35．推理判断题。文章开篇介绍了雪崩的定义和速度，接着阐述了雪崩发生的原因、危害，以及滑雪爱好者的注意事项等内容，整体围绕着“雪崩”这种自然灾害展开介绍，所以作者写这篇文章主要是为了介绍一种自然灾害。故选C。 学科网（北京）股份有限公司 ( 1 )原创精品资源学科网独家享有版权，侵权必究！ 学科网（北京）股份有限公司 $ 编写说明：本套试卷紧扣《英语 基础模块1》（外研版第二版）教材，以教材单元为基准精准覆盖核心考点。 每个单元设置AB卷，A卷为基础巩固卷，侧重基础考点训练，帮助学生扎实掌握知识要点；B卷为能力提升卷，注重知识整合与全面检测，引导学生构建知识网络。模拟实战情境，聚焦解题能力突破，全面提升应试能力与知识应用水平。 《英语 基础模块1》（外研版第二版）《单元过关卷》 Unit 7 When Disaster Strikes A卷·基础巩固 考试时间：40分钟 满分：100分 班级 姓名 学号 成绩 一、单项选择。从每题所给的A、B、C和D四个选项中，选出最佳选项。 (每小题2分，共50分) 1.
