Artificial intelligence (人工智能), or AI in short, is the science of giving computers and machines ability to think and work like humans. AI scientists and engineers have made a lot of cool technologies.
AI is rapidly catching up with the human ability to read faces. As a result, facial recognition (识别) is used a lot in the world. Chinese police use this technology to identify criminals (罪犯). Once they caught a criminal when he attended a concert. It also checks the ID of ride-hailing (网约车) drivers and lets people pay for things with a smile.
AI is also used in self-driving cars, which are believed to be the future of driving. Most drivers may wave or nod at passers-by to let them cross the street, but self-driving cars don’t have this ability. Car makers are testing a light signal system to help them “speak” to humans. The system can show what self-driving cars will do. For example, if a driverless car is yielding (让路), it will flash two white lights side to side. A rapidly flashing light tells passers-by that the car is about to speed up.
Service Robots also show you how powerful AI is. Imagine this—you come back home from school and your robot housekeeper is waiting for you at the door. After dinner, he teaches you to play the piano, just like a real music teacher. Such thoughts will soon happen in the real world. In the future, more and more service robots will become good home helpers.
AI is so powerful that it can help human beings and even replace us in many jobs.

【推荐2】“Five, four, three, two, one, blast off.” At 0:23 on October16, 2021, China launched the manned spaceship Shenzhou-13, sending three astronauts to its Tiangong space station. About 6.5 hours after the launch, the spaceship successfully docked (对接) with the Tianhe core module of the station.
The three-person team is the second crew (工作组) to have entered Tiangong. The team is led by China’s first space walker Zhai Zhigang. The other two astronauts are Wang Yaping and Ye Guangfu. They will live and work together at the station for six months. This will be China’s longest-ever manned mission.
During their six-month stay, the crew will carry out a number of tasks. For example, they will do two to three spacewalks to fix equipment in preparation for future construction work. Wang Yaping, the first Chinese woman to perform spacewalk, said “Apart from the tasks, we also hope to do more space science education. This will bring space closer to the general public. As a result, they will learn more about the astronauts’ life in space.”
Shenzhou-13 was China’s last major space mission in 2021. Another six missions are planned for this year to finish the construction of the space station. Once its completed, Tiangong will be about one-fifth the size of the International Space Station (ISS). The ISS will reach the end of its life in 2024. Tiangong is likely to be the only operational near-Earth orbit (近地轨道) space station by then. China looks forward to hosting astronauts from other countries.
Denis Simon, at Duke Law in the US, told Xinhua that China’s success in space continues to be impressive (令人赞叹的). “It is now well on its way to being a leader in space exploration.” he said.

【推荐3】What would you like for lunch? Maybe, a battery (电池)? Although it sounds unusual, this has already been realized by scientists as they develop electronic things you can eat.
Robofood, led by Dario Floreano from a Swiss Institute, has created a new drone (无人机) with scientists from Wageningen University, the Netherlands. Half of the parts inside can be eaten! The program aims to (旨在) make robots that can be eaten and foods that act like robots by mixing food science and robots in a new way.
The drone’s wings are made from rice cakes glued together with oil and chocolate. It can find missing people or animals in emergencies (紧急情况) and send food or medicine. Parts of the drone can be eaten because they meet food safety standards for emergencies set by the United Nations.
However, the main challenge is finding stronger edible (可食用的) materials for the drone’s wings to prepare for bad weather and high temperatures—of course, the chocolate may melt (融化) easily.
Robofood also developed an edible sensor (感应器) to help monitor (监控) stomach sickness, and it’s eaten by the patient to check the conditions inside. It’s different from other sensors because it’s easy for your body to digest (消化), so it won’t leave any remains inside the body.
The invention of Robofood also helps with environmental protection. There are batteries that you can fully eat. They are made from natural things like vitamin B2 and elements (元素) found in fruits. This helps the environment because you won’t have to throw them away like other batteries.

【推荐1】A total of 3.41 million people were expected to take part in China’s 2021 national entrance exam for postgraduate(研究生) studies, 0.51 million more than last year, the Department of Education said.
That’s a rise of 17.5 percent, and with a record 8.74 million university students expected to graduate next year, a survey by education website found that growing competition in the job market was the primary reason for the increase. When asked whether postgraduate study would help them find a job, 57 percent of exam applicants(应聘者) said they believed it could make them more competitive in the job market, 42 percent said it would be somewhat helpful, and only 1 percent did not expect it to improve their chances. When asked why they wanted to get a master’s degree(硕士学位), 61 percent of them said it would improve their competitiveness in the job market, 53 percent said they wanted to get a higher degree. 25 percent said they did not like their undergraduate majors(本科专业), and 25 percent said they wanted to wait for a few years before entering the job market.
Zhang Sijia, 22, who studies at the University of Science and Technology Beijing, says, “It’s impossible that I cannot find a job if I enter the job market now, but I think a master’s degree in finance will give me better chances to find a high-paying job,” she said. Many jobs have higher academic(学术的) requirements nowadays. “Almost half my classmates have signed up for the exam, as getting higher degrees has become necessary if you want to find a better job,” Zhang said.

【推荐2】Terrible weather events are harming the planet (星球,地球), and experts warn of even greater results to come. The sea ice loss and the Arctic (北极的) ice melting (融化) caused by climate change have increased much in the last ten years. So they have pushed down the number of polar bears (北极熊) and seals while polar bears depend on sea ice for hunting seals (海豹).
According to the data from the WMO, temperatures on the Antarctica (南极洲) just hit 18.3℃, which is higher than the record of 17.59℃ in March, 2015. Moreover, temperatures in this area have warmed about 3℃ over the last 50 years. Although such temperatures might be considered pleasant for a picnic or a hiking trip, this is the Antarctica we are talking about. It is home to the most inhospitable environment on the planet because it is supposed to be an extremely cold place. In fact, the average temperature of the continent’s central area is -57℃.
Besides, many places are experiencing the extreme weather this summer. Australia is undergoing its worst drought (干旱) since the 1930s, leaving bush fires (丛林大火) burning so long and causing many deaths. Meanwhile in Europe, crops in the northwest are suffering the driest weather in the past 80 years. Recently West Texas in America has also gone through its worst drought in more than 70 years, while floods have hit Eastern and Southern China.
“Climate change is bad for us human beings, which causes direct health problems. I’m afraid there will be more common events like the one that 30,000 to 50,000 persons died in Europe in 2003 due to the heat wave there,” Professor Schwartz said. “It will also cause more air pollution, diseases and lack of clean water and so on.”

Taj Mahal is considered to be one of the most beautiful buildings in the world and the finest examples of the late style of Indian architecture(建筑). It is at Agra in northern India. It lies beside the Yamuna River in the middle of gardens with quiet pools.
Taj Mahal was built by the emperor Shah Jahan. He ruled India in the seventeenth century. It is in memory of his favourite wife, Arjumand Banu Bagam, known as Mumtaz Mahal, who died in 1631. The building was designed by a local Muslim architect, Ustad Ahmad Lahori. The whole building, with gardens and gateway structures, was completed in 1653. Taj Mahal stands at one end of the garden tomb with a marble(大理石) path. The room is softly lit by the light that passes through double screens of carved marble set high in the walls. The building now is kept in good condition.
It took 22 years to build Taj Mahal. Shah Jahan also planned a similar building, but in black instead of white, to lie on the other side of the river. But before it could be built, Shah Jahan was imprisoned(监禁) by his son and buried(埋) next to his wife in Taj Mahal after his death.
