What can drones do? Their many uses include taking pictures from the sky, observing（观察）wild animals and delivering packages. Now these small flying robots are leading a new farming revolution（革命）, according to the Food and Agriculture Organization of the United Nations.
When equipped（装备）with cameras and other data-gathering devices, drones provide us with an eye in the sky. Here are a few of the farming-related jobs drones can do.
Looking for sick crops
Drones can scan（扫描）crops using different kinds of light. Then, they produce multispectral images（多谱图像）that can help us find sickly yellow plants within fields of green. Drones can also detect bacteria（检测细菌）that are harmful to crops in the air from a few kilometers away. Farmers can check the drones’ air samples（样本）and try to find ways to protect their crops before the bacteria get to them.
Counting cattle
When flying over cattle, drones can track the livestock and find out where fences need fixing. People can also equip drones with thermal imagers（热像仪）and night-vision cameras. This can help farmers look for animals that could harm their cattle.
Water watch
Most fields aren’t perfectly flat（平坦的）. After watering, some places may dry out faster than others. Other spots might not get water at all. Drones can scan the field and make a 3-D map. Using the map, farmers can figure out which parts of a field are dry or need improvement.
Spraying pesticide（喷洒农药）
Different parts of a field might be uneven or have different altitudes（高度）. Drones can check for this when flying above the land. Then, they change their height and therefore spray the correct amount of pesticide over each part of the field. This is more efficient than traditional pesticide spraying. Drones can finish spraying a field up to five times faster than with traditional machinery, according to a study from MIT.

| A．Drones can’t detect bacteria unless crops are sick. |
| B．Drones can fight dangerous animals. |
| C．Drones can help farmers make sure fields are properly watered. |
| D．Drones are better at spraying pesticide over flat land. |

【推荐1】If you look around the room you are in right now, you’ll probably notice a number of electronics. But can you imagine if they all had to be joined together by wires (电线)? Picture the wire snaking along the floor, for example, from your smartphone to your speaker, or connecting your game controller to the computer screen, meaning you could never sit more than a couple of meters away from it. A world of electronics connected by wires wouldn’t just be untidy, but a possible danger, too. That’s where Bluetooth comes in. We’ve all heard of it — but what exactly is it?
Bluetooth is a method of short-distance (短距离) wireless communication between electronics that makes use of the power of radio waves. The idea was first thought of by Dr. Janp Haartsen at Swedish mobile company Ericsson in 1994. Things really stepped up in September 1998 when the Bluetooth Special Interest Group (SIG) was set up to develop and spread the technology. Bluetooth 1.0 came out in 1999, and a year later it began to be used in mobile phones and desktop computers. Now Bluetooth has become an increasingly popular way of solving the problem of more and more electronics needing to be connected. without having to connect everything together with wires.
But if you look at the remote control (温控器) you use to choose the program on TV, you might rightly ask yourself why Bluetooth was such a big deal. After all, connecting objects with infrared signals (红外信号) which can’t be seen had been done before. The problem with remote controls is that they need to keep what is called “line of sight”. If something is standing between the remote control and receiver, it won’t work. Because Bluetooth uses radio waves, the things standing in the way are no longer a problem.
Since its creation in the late 1990s, the technology has become more and more improved and widely used, with the 4 billionth Bluetooth objects shipped in 2020.
1. How does the writer lead in the topic “Bluetooth” in Paragraph 1?| A．By describing scenes. | B．By comparing facts. | C．By telling stories. | D．By explaining reasons. |
| A．started to be used in cars | B．made radio waves known to people |
| C．improved and spread quickly | D．was able to connect all electronics |
| A．development | B．popularity | C．standard | D．advantage |
| A．Phone sellers | B．Technology fans | C．Newspaper reporters | D．History lovers |
【推荐2】Superfast Writing Robot
Tech company has made a powerful robot that can write novels.
Type in (输入) “A cat wants to go to space” and ask the robot to write a bedtime story. Just one second later, you’ll get a story of a cat called Max, who was on his way past many difficulties to sing among the stars.
This robot writer is real. It’s called ChatGPT. US company Open AI developed it to make up human-like texts. It can translate languages, talk with people and write songs, poems and even jokes. It’s one of the most powerful AIs of its kind, with the complete writing skills of a real person!
People around the world have tried ChatGPT and posted their results on social media. Some used it to write history articles, some asked it to take notes or give advice on how to communicate with people at a party, reported Thne Atlantic.
The power of ChatGPT lies in its speed and understanding of complicated (复杂的) matters. We may spend hours researching, understanding and writing an article on a certain topic. But ChatGPT can produce a well-written one in seconds. Another good thing about it is that if you ask dark, harmful questions, such as how to make weapons (武器), it will not give you an answer.
ChatGPT appears at a time when AI is becoming better at doing creative tasks. The materials they create are difficult to distinguish (区分) from those made by humans. This also causes many problems, such as the copyright (版权) and the definition (定义) of art. They are still waiting for humans to solve.
1. The writer uses “the story of the cat” as an example to ________.| A．show what creative work ChatGPT can do | B．introduce a cat that wants to go to space |

【推荐3】What is the most important invention of all time? Is it the written word that helps us to record information? Is it the telephone that lets us talk to people from all over the world? Is it the car that let us travel at great speeds to meet others? Umberto Eco, an Italian writer, thinks it is something quite different. He says the most important invention might be right in front of your eyes. He is talking about a simple pair glasses.
Modern eye glasses were invented around 1000 years ago. They were more than just a convenient way to read. Before glasses, writers, scientists or teachers who could not see properly had to memorize everything. After about ten years of poor eyesight, they could not remember well enough and could not work. Glasses meant that people could work in their old age. People who wanted to remember some information could write it down and read it. Eye glasses are one of the world’s greatest inventions and were probably worn by the people who designed the first telephone and car.

【推荐1】On April 18th—the International Day for Monuments and Sites, China Daily’s digital employee Yuanxi and Dunhuang Mogao Grottoes’ official virtual (虚拟的) cartoon figure Jiayao together introduced an interactive digital platform (数字化互动平台) that hosts a virtual copy of the Mogao Grottoes’ Library Cave to the world.
The platform was developed jointly by the Dunhuang Academy and the Chinese tech firm Tencent. It uses gaming technologies to show the historical scenes of the Library Cave in the digital world.
The Library Cave in Mogao Grottoes was discovered in 1900, with more than 60,000 cultural relics dating from the 4th century to the 11th century unearthed. It was one of the most important archaeological discoveries in the 20th century.
On the platform, visitors can role-play and “time travel” to ancient dynasties and talk with eight historical figures. The public can enter the platform through the Digital Dunhuang website and its WeChat mini program.
In the digital age, the model of “culture+technology” has been adopted to promote (促进) the development of Chinese culture. The digitalization rate of China’s precious cultural relics has been more than 70 percent, according to the 2022 China Digital Collection Industry Research Report released by iResearch.
The Ministry of Culture and Tourism has also encouraged the development and transformation (转型) of cultural intellectual property by digital means. CCTV (China Central Television) has created a series of digital collections with different Dunhuang themes, such as the Dunhuang divine deer Youyou. It was created based on the image of the nine-colored deer from Dunhuang murals. The public can see the divine deer on CCTV’s own digital platform.
Digital collections cater to (迎合) the consumption habits of young people. They not only protect the intellectual property of the collections but also bring the public closer to China’s “excellent traditional culture”, noted Dunhuang Art Institute.
Su Bomin, director of the Dunhuang Academy, told Xinhua that more efforts will be made to explore new forms for showing cultural relics and offer the public more immersive cultural experiences to develop Dunhuang culture.

 Many new kinds of stationery are invented these years. And they already entered the daily life of students. Have you ever bought such products? Do you think such “high-tech” stationery（文具）is helpful? Here are some different opinions. | |
Dong I have many products of such stationery. I bought them not only for their looks but also for their usefulness. Actually, with the “high-tech” products, life becomes much more convenient. For example, by using the electric pencil sharpener, you won’t get your hands dirty or waste time cleaning your desk. What a great helper! Zhong Such stationery is handy and convenient. They are useful. For example, they save time. It takes only 5 to 10 seconds（秒）to clean your desk with an electric cleaner but will take about 20 seconds by hand. You may think a few seconds doesn’t matter. But after 100 times of doing it, it will be a lot of time. So be open-minded and try new things. | Qiu I don’t buy such “high-tech” stationery. Stationery is study tools that should be useful, not for playing with. They can easily distract students in class. Students might spend a longer time on simple things. And, high-tech stationery is usually expensive. My stationery is normal and completely enough for daily use. Wang I don’t think such stationery is necessary. I find that some of my classmates are just busy playing with them and showing off in front of others. They may have forgotten that the stationery should actually be used to help make their study life easier, but not make them ignore（忽略）what they are learning. |

【推荐3】ChatGPT is back in the headlines. Open AI, the company behind the popular chatbot has now introduced a powerful new language model: GPT-4.
On March 14, GPT-4 showed the world how smarter it is than the previous GPT-3.5. One of its best new features is that it can understand pictures. For example, if you show a picture of a phone using the wrong charger, GPT-4 can tell why the picture looks strange or funny.
But GPT-4’s developments don’t stop there. The new language model can code classic games like Tetris (俄罗斯方块) in a matter of minutes, and produce the code and layout (布局) for a website based on a handmade drawing. It can also change the tone and style based on what you ask it to do. GPT-4 is much better than the older GPT at passing tests, which may worry teachers. According to CNN, GPT-4 did really well on a law school test, with a score in the top 10 percent of test takers. But GPT-3.5 only got a score in the bottom 10 percent.
GPT-4 will also see greater use as a tool to power other apps and services. For example, the language learning app Duolingo plans to use GPT-4 in their upcoming version, Duolingo Max. Users can learn language by talking with AI. Another app, Be My Eyes, will have a digital assistant to help blind people better understand the world around them. The government of Iceland also plans to use GPT-4 to protect the Icelandic language.
There are still problems with the new language model, however. GPT-4 struggles to get completely correct answers, especially with newer information after September 2021. GPT-4 also sometimes “hallucinates”, meaning that it will insist that wrong information is true.
1. What can we infer from Paragraph 2?| A．GPT-4 can create funny pictures. | B．GPT-4 can tell if a phone is recharging. |
| C．GPT-3.5 cannot understand pictures. | D．GPT-4 cannot respond faster than GPT-3.5. |
①understanding pictures ②coding classic games
③producing the layout for a website ④changing the tone and style
⑤getting completely correct answers ⑥powering other apps and services
| A．①②③④⑤ | B．①②④⑤⑥ | C．①②③⑤⑥ | D．①②③④⑥ |
| A．GPT-4 can beat 90% of human test takers in all tests. |
| B．GPT-4 is less preferred by apps and services. |
| C．GPT-4 sometimes is unable to decide whether the information is true or not. |
| D．GPT-4 couldn’t get correct answers before Sept 2021. |
| A．A technology newspaper. | B．A science fiction. |
| C．A computer guidebook. | D．A fashion magazine. |
【推荐1】Most people will tell you that they can’t work without a cup of coffee in the morning. Research has shown that a cup of coffee does give a person slight excitement.
Legend said that Kaldi, an Ethiopian, found his goats happier while enjoying coffee plants. Curiously, he tasted the leaves and began to dance around. Whether the Legend was true or not, the discovery of coffee dates back to 800A. D. Soon Arabians were roasting coffee beans. Muslims were drinking coffee to stay awake by 1000 A.D. A merchant from Venice introduced coffee to Europe in 1615. By 1696, the Dutch started growing the coffee bush in Java. By 1723, coffee plants were introduced to the Americans. Today, coffee is the most popular drink in the world.
Caffeine is the major chemical in coffee. It blocks(阻止) adenosine, a chemical that makes you sleepy. People can get a pick-me-up or stimulation(刺激) from the drink. The stimulation does not last long. Caffeine poisoning can occur if more than 400 milligrams of caffeine is drunk in a short period, which is about four to five cups of coffee. Caffeine will also cause sleep difficulty, so it should not be drunk before bed.
Caffeine has many advantages. Studies have shown that it helps improve some skills in elderly women. Women who drank three cups of coffee daily scored higher on memory tests than women who drank one cup of coffee. According to newser.com, one cup of coffee a day protects the brain. Coffee also can help people keep away from many diseases according to webmd.com.
Large amounts of coffee can cause nervousness, worries and a fast heartbeat. However, if you mix coffee with milk, it’s fine. Caffeine can be addictive like any drug. The more you drink, the more you depend on it. For some people, just one cup of coffee a day is OK.

【推荐2】Do you know Black Friday? It is the day following Thanksgiving Day (the fourth Thursday of November) in the United States. People think it means the beginning of the Christmas shopping season in the US, and most stores and shopping malls open very early. Things will be on great sale for people to buy.
Black Friday is not a holiday, but California and some other states(州) in the USA think it as a holiday just for some people who don't work in shops like officers, teachers and students. They can have holidays both on Thanksgiving and on the following Friday. In this way, they make it a four-day weekend, so more people can go shopping during these days. It is the busiest(最繁忙的) shopping day of the whole year in America. Like the Double Eleventh Day in China.
Black Friday first appeared in Philadelphia. People used the word to describe the heavy traffic jam(堵塞) and the most crowded streets on the day after Thanksgiving, because people all went into the shopping malls and shops to buy things they wanted. It brought a lot of trouble to the drivers and policemen. And also on this day, the business could move into "black", and this meant that it helped the shop owners make a lot of money. That was why people called it "Black Friday". More than twenty years later, the phrase became more and more popular.

【推荐3】When you are at the beach and stay for a few hours, you may notice that the water level of the sea or ocean is rising or falling. This change in sea level happens as the tide (潮汐) goes in and out.
Tides are caused by the effect of the moon’s gravity on the earth, and to a lesser extent, the sun’s gravity. Even though the sun is much bigger than the moon and the earth, it is very far away so the tides on earth are mostly affected by the moon.
The earth’s surface is 70% covered in water. The gravity of the moon creates a pull on the side of the earth closest to it. This pull creates a “bulge”of water on the side of the earth the moon is closest to. This is what we call “high tide”. As well as the side closest to the moon having high tides, the opposite side of the earth does too. The sides not experiencing the “bulge” are experiencing what we call “low tides.” Since the moon goes around the earth, high and low tides follow the movement of the moon.
Two high tides and two low tides occur(出现) every 24 hours. Fast movement of water during the inflow and outflow can provide a source of renewable energy. When the water goes out to sea signaling a low tide, it washes away garbage and pollution from the land. Scientists are able to predict when high and low tides will happen, which is very important because some ships cannot dock on land when there is a low tide. The predictability (可预测性) of the tides is very important for fishermen as well. High tides bring fish closer to land so people can catch fish faster and easier.

【推荐2】Last summer I went to one of the world’s most famous historical places, the Forbidden City in Beijing, China. It was the home of the emperors (皇帝) of the last two dynasties (朝代) in China, the Ming and Qing Dynasties.
The Forbidden City was built in 1,420. The palace has over 10,000 rooms. It was where the emperors dealt with the official business with their ministers (大臣).
In Mandarin (普通话), the Forbidden City is called the Purple Forbidden City. However, the color of the palace itself is not purple. The color purple stands for power of the great emperors of China. It was so sacred (神圣的) that the common people could not even dream of ever going in.
The emperor also had some of the largest festival celebrations at the Forbidden City. During Chinese New Year, the emperor would invite all the members of his family and his officials to a banquet. The banquet had a hundred and eight Chinese dishes. It was such an expensive banquet that it could feed a common family for three generations (三代人).
Right now the Forbidden City is known as a historical site for tourists from all over the world. Everyone can go in there. It is a museum with priceless Chinese antiques (古董) and treasures in it.
I really learned a lot about the Chinese culture and its history from this trip to the Forbidden City. It was like a dream which has come true. And I was excited to go on the trip and see the things that I had always wanted to see.
