It is much faster than 4G. With 5G, you can download (下载) a full movie in just a few seconds. But speed is not the only advantage. 5G also has very low latency . This means there is almost no delay between sending and receiving information. This is very important for things like self-driving cars and remote surgeries (远程手术), where every millisecond (毫秒) matters. In factories, 5G allows machines to "talk" to each other in real time. Workers can control robots from far away, making production safer and more efficient (高效的). In schools, students can use VR headsets to visit museums or even the bottom of the ocean without leaving the classroom. As 5G networks spread across the world, our daily lives and many industries will be changed in exciting ways. 1. What is a key advantage of 5G mentioned in the passage? A. Much faster speed. B.

The rest becomes heat. This is why old-style light bulbs get very hot and waste a lot of energy. LED lights are very different. They can turn about 80-90% of electricity into light, which means they use much less power to produce the same brightness (亮度). An LED bulb can last 15 to 25 times longer than a traditional one. Although an LED bulb costs more to buy at first, it saves you money in the long run because it uses less electricity and needs to be replaced much less often. Switching to LED lights is one of the easiest ways to save energy at home and at school. Many cities have already replaced their street lights with LEDs. If every family in a city replaced just one old bulb with an LED, the energy saved could power thousands of homes for a year. Small changes can make a big difference. Next time a bulb burns out, why not try an LED? 6. How much electricity does a traditional light bulb turn into light? A. About 50%. B. About 80%. C. About 90%. D. About 10%. 7. How much longer can an LED bulb last compared to a traditional one? A. 15 to 25 times. B. 5 to 10 times. C. 30 to 40 times. D. 50 to 60 times. 8. What is one disadvantage of LED bulbs mentioned in the passage? A. They are not bright enough. B. They produce too much heat. C. They cost more to buy at first. D. They cannot be used in homes. 9. The underlined word "Switching" means ______. A. Turning off. B. Changing. C. Repairing. D. Buying. 10. What is the writer's purpose in writing this passage? A. To explain how light bulbs are made. B. To compare electricity prices in different cities. C. To describe the history of lighting. D. To encourage people to use LED lights. 【答案】6. D 7. A 8. C 9. B 10. D 【解析】 【导语】本文通过对比传统灯泡和LED灯在能效、使用寿命和成本上的差异，鼓励人们在家庭和学校中使用LED灯来节约能源。 6. 细节理解题。根据文中"a traditional light bulb turns only about 10% of the electricity it uses into light（传统灯泡只将大约10%的电能转化为光能）"可知，传统灯泡的光转化率约10%。A选项About 50%、B选项About 80%、C选项About 90%均与文中数字不符。故选D。 7. 细节理解题。根据文中"An LED bulb can last 15 to 25 times longer than a traditional one.（LED灯泡的寿命是传统灯泡的15到25倍。）"可知，LED灯泡的寿命是传统灯泡的15到25倍。B选项5 to 10 times、C选项30 to 40 times、D选项50 to 60 times均与文中数据不符。故选A。 8. 细节理解题。根据文中"Although an LED bulb costs more to buy at first（虽然LED灯泡最初购买时更贵）"可知，LED灯泡的缺点是初始购买成本高。A选项They are not bright enough（不够亮）、B选项They produce too much heat（产生过多热量，这是传统灯泡的缺点）、D选项They cannot be used in homes（不能在家中使用）均与文中信息不符。故选C。 9. 细节理解题。根据文中"Switching to LED lights is one of the easiest ways to save energy — Switching意为"更换、改用""可知，Switching意为改用、更换，对应Changing。A选项Turning off（关闭）、C选项Repairing（修理）、D选项Buying（购买）均不符合从旧灯泡换成新灯泡的语境。故选B。 10. 细节理解题。根据文中"Next time a bulb burns out, why not try an LED?（下次灯泡坏了，为什么不试试LED呢？）"可知，鼓励人们使用LED灯。A选项To explain how light bulbs are made（解释灯泡如何制造）、B选项To compare electricity prices（比较电价）、C选项To describe the history of lighting（描述照明历史）均不是文章的主要内容。故选D。 Passage 3 Paper cutting (剪纸) is one of the oldest folk arts in China, with a history of over 1,500 years.
