However, this wasn’t always the case. The story of electricity began thousands of years ago with simple discoveries. The ancient Greeks found that when they rubbed (摩擦) amber (琥珀) with cloth, it could attract small objects. They thought it was like a magnet (磁体), but it was actually static electricity (静电). The ancient Egyptians discovered electric fish in the Nile River and called them “Thunder of the Nile”. In the 17th century, William Gilbert studied the difference between magnets and static electricity, creating the word “electrica”. Later, Benjamin Franklin conducted experiments that proved lightning was a form of electricity. He also studied how to store electric charge (电荷). Alessandro Volta made the first battery using layers of two different metals. This important invention provided steady (稳定的) electric power. Michael Faraday then used Volta’s ideas to build the first machines that could power things with electricity and create electricity. In 1879, Thomas Edison created the modern light bulb, improving earlier designs. Two years later, his colleague Lewis Latimer made it more practical by inventing a longer-lasting filament (灯丝). These inventions changed the way we live and led to many more discoveries that shape our modern world. 1. What did the ancient Greeks discover about electricity? A. Magnets attracting metal. B. Static electricity from amber. C. Lightning in thunderstorms. D. Electric fish in the Nile River. 2. According to the passage, what did William Gilbert do? A. He made the first electric battery. B. He created new electrical machines. C. He found fish that produced electricity. D. He compared magnets with static electricity. 3. What’s the relationship between Edison’s and Latimer’s work? A. Their work had no relationship. B. Edison built on Latimer’s work. C. They made the same discovery. D. Latimer improved Edison’s design. 4. How is the information in this passage organized? A. In order of the location. B. In order of time. C. In order of the country. D. In order of importance. 【答案】1. B 2. D 3. D 4. B 【解析】本文主要按时间顺序介绍了电的发展历史。 1. 细节理解题。根据第二段“The ancient Greeks found that when they rubbed (摩擦) amber (琥珀) with cloth, it could attract small objects. They thought it was like a magnet (磁体), but it was actually static electricity (静电).”可知，古希腊人发现了静电现象。故选B。 2. 细节理解题。根据第三段的第一句“In the 17th century, William Gilbert studied the difference between magnets and static electricity, creating the word ‘electrica’.”可知，威廉·吉尔伯特研究了磁铁和静止电荷之间的区别，并创造了“电”这个词。故选D。 3. 推理判断题。根据最后一段“Thomas Edison created the modern light bulb, improving earlier designs. Two years later, his colleague Lewis Latimer made it more practical by inventing a longer-lasting filament (灯丝).”可知，拉蒂默是对爱迪生的发明进行了改进。故选D。 4. 推理判断题。由全文内容可知，整篇文章按时间顺序来组织内容。故选B。 B There is a great need to search for clean and renewable(可再生的) energy to meet our needs. It seems that wind energy is a good choice. Do you know anything about wind energy? The first advantage of wind energy is that it truly is a renewable resource. No matter how much wind we use to produce electricity, we will never reduce the supply(供应) of wind. This is its greatest advantage compared with non-renewable resources like coal or oil. Second, wind energy is a clean source of energy, which means it produces environment-friendly electricity. What’s more, the large towers,which provide the base for the wind turbines(涡轮机), don’t take up lots of space. They can share land with farms. However, each coin has two sides. That is to say wind energy does have some disadvantages. Wind does not provide supply of energy without stopping. Even the windiest places on earth have periods of calm. If there isn’t a strong wind, wind turbines are not able to produce electricity. The large blades of wind turbines can be very dangerous for birds and bats. The turbines cause noise pollution. It can also be bad to people living around. Although wind energy has disadvantages, its advantages shouldn’t be forgotten. 5. People search for ________ to meet their needs according to the passage. A. electricity B. coal and oil C. non-renewable energy D. clean and renewable energy 6. How many advantages of wind energy are talked about in the passage? A. One B. Two. C. Three D. Four 7. What does the underlined word “They” refer to in Paragraph 2? A. The large towers. B. Wind turbines C. Energy resources. D. Renewable resources 8. What’s the main idea of Paragraph 3? A. Wind energy also has some disadvantages B. Wind can't provide energy without stopping C. The blades of wind turbines can be very dangerous D. The turbines cause noise pollution while working 9. According to the passage, we know that ________. A. wind energy is a non-renewable resource B. the greatest advantage of wind energy is renewable C. the windiest areas never have periods of clam D. wind turbines can't be dangerous for birds and bats 【答案】5. D 6. C 7. A 8. A 9. B 【解析】本文主要介绍风能发电的优势和劣势。 5. 细节理解题。根据“There is a great need to search for clean and renewable(可再生的) energy to meet our needs.”可知，人们在搜索干净的和可再生的能源来满足他们的需求。故选D。 6. 细节理解题。根据“The first advantage of wind energy is that it truly is a renewable resource.”；“Second, wind energy is a clean source of energy, which means it produces environment-friendly electricity. ”；“What’s more, the large towers,which provide the base for the wind turbines(涡轮机), don’t take up lots of space.”可知一共是3个优势，故选C。 7. 词义猜测题。根据“What’s more, the large towers,which provide the base for the wind turbines(涡轮机), don’t take up lots of space. They can share land with farms.”可知本句说的话题是“large towers”，它们不占空间，可以和农业共用陆地。故“They”指的是“large towers”。故选A。 8. 段落大意题。根据“However, each coin has two sides. That is to say wind energy does have some disadvantages.”可知本段主要讲风能也有劣势。故选A。 9. 细节理解题。根据“This is its greatest advantage compared with non-renewable resources like coal or oil.”可知可再生是风能相比其他不可再生能源最大的优势。故选B。 原创精品资源学科网独家享有版权，侵权必究！2 学科网（北京）股份有限公司 $$ Unit 6 Electricity everywhere Section 1 Listening and Section 3 Speaking 一、语音考查 A、找出下列单词中重音位置与其他不同的单词。（考查音节的划分） 1.

The story of electricity began thousands of years ago with simple discoveries. The ancient Greeks found that when they rubbed (摩擦) amber (琥珀) with cloth, it could attract small objects. They thought it was like a magnet (磁体), but it was actually static electricity (静电). The ancient Egyptians discovered electric fish in the Nile River and called them “Thunder of the Nile”. In the 17th century, William Gilbert studied the difference between magnets and static electricity, creating the word “electrica”. Later, Benjamin Franklin conducted experiments that proved lightning was a form of electricity. He also studied how to store electric charge (电荷). Alessandro Volta made the first battery using layers of two different metals. This important invention provided steady (稳定的) electric power. Michael Faraday then used Volta’s ideas to build the first machines that could power things with electricity and create electricity. In 1879, Thomas Edison created the modern light bulb, improving earlier designs. Two years later, his colleague Lewis Latimer made it more practical by inventing a longer-lasting filament (灯丝). These inventions changed the way we live and led to many more discoveries that shape our modern world. 1. What did the ancient Greeks discover about electricity? A. Magnets attracting metal. B. Static electricity from amber. C. Lightning in thunderstorms. D. Electric fish in the Nile River. 2. According to the passage, what did William Gilbert do? A. He made the first electric battery. B. He created new electrical machines. C. He found fish that produced electricity. D. He compared magnets with static electricity. 3. What’s the relationship between Edison’s and Latimer’s work? A. Their work had no relationship. B. Edison built on Latimer’s work. C. They made the same discovery. D. Latimer improved Edison’s design. 4. How is the information in this passage organized? A. In order of the location. B. In order of time. C. In order of the country. D. In order of importance. B There is a great need to search for clean and renewable(可再生的) energy to meet our needs. It seems that wind energy is a good choice. Do you know anything about wind energy? The first advantage of wind energy is that it truly is a renewable resource. No matter how much wind we use to produce electricity, we will never reduce the supply(供应) of wind. This is its greatest advantage compared with non-renewable resources like coal or oil. Second, wind energy is a clean source of energy, which means it produces environment-friendly electricity. What’s more, the large towers,which provide the base for the wind turbines(涡轮机), don’t take up lots of space. They can share land with farms. However, each coin has two sides. That is to say wind energy does have some disadvantages. Wind does not provide supply of energy without stopping. Even the windiest places on earth have periods of calm. If there isn’t a strong wind, wind turbines are not able to produce electricity. The large blades of wind turbines can be very dangerous for birds and bats. The turbines cause noise pollution. It can also be bad to people living around. Although wind energy has disadvantages, its advantages shouldn’t be forgotten. 5. People search for ________ to meet their needs according to the passage. A. electricity B. coal and oil C. non-renewable energy D. clean and renewable energy 6. How many advantages of wind energy are talked about in the passage? A. One B. Two. C. Three D. Four 7. What does the underlined word “They” refer to in Paragraph 2? A. The large towers. B. Wind turbines C. Energy resources. D. Renewable resources 8. What’s the main idea of Paragraph 3? A. Wind energy also has some disadvantages B. Wind can't provide energy without stopping C. The blades of wind turbines can be very dangerous D. The turbines cause noise pollution while working 9. According to the passage, we know that ________. A. wind energy is a non-renewable resource B. the greatest advantage of wind energy is renewable C. the windiest areas never have periods of clam D. wind turbines can't be dangerous for birds and bats 原创精品资源学科网独家享有版权，侵权必究！2 学科网（北京）股份有限公司 $$
