1 . In the rich countries of the West, the electric vehicle revolution is well occurring. Climate-conscious consumers drive Teslas or Polestars for reasons of morality (道德) and fashion. Poorer countries are also experiencing a wave of electrified trend. In Bangladesh, electric three-wheeler taxis, known as tuk-tuks, are rapidly replacing gas-powered ones on the streets. Such electric vehicles are climate friendly, cost effective, and help reduce air pollution.
Yet a glance under the hood (引擎盖) of these vehicles shows a poisonous secret: each tuk-tuk runs on five massive lead-acid batteries (铅酸电池), containing almost 300 pounds of lead (铅) in total. Every year and a half or so, when those batteries need to be replaced and recycled, about 60 pounds of lead leaks into the environment. Battery recycling, often at small-scale unregulated factories, is a highly profitable (高利润的) but deadly business.
Lead is dangerous, and any exposure to it is harmful to human health. Lead that has entered the environment hurts people on an unexpected scale. The numerous ways lead enters air, water, soil, and homes across the developing world and the enormous damage it does to human health, wealth, and welfare cause one of the biggest environmental problems in the world yet receives little attention.
The World Bank estimates that lead kills 5.5 million people per year, making it a bigger global killer than AIDS, malaria, diabetes, and road traffic deaths combined. On top of the shocking deaths, the social burden of lead poisoning is heavy, as is its contribution to global inequality — our research on the cognitive (认知的) effects of lead poisoning suggests that it may explain about one-fifth of the educational achievement gap between rich and poor countries.
But unlike many challenges faced by developing countries, lead poisoning is a problem that can be resolved through financial investment (财政投入). Better monitoring, research, and rules can help protect children all over the world from the unpleasant effects of lead poisoning and reduce the massive global costs it brings.

2 . “Pop” stands for popular, and a pop singer has to work very hard to stay popular. He must either give the public what they want, or he must find a new way of singing that will attract their attention. Even when he has succeeded, and his records are sold everywhere, he cannot relax. Then he must work harder than ever to remain popular, because there are always younger singers trying to become famous and to steal some of the popularity.
The life of a successful pop singer isn’t easy at all. He can only relax when he is alone, because everything he does is watched and reported in the special newspaper written for the fans. The fans are the most important people in the world for the singer. They buy his records, they go to his concerts, and they make him rich and famous. But they can be very annoying, too. Sometimes their enthusiasm (热情) is so hysterical (歇斯底里的) that they do anything to get a souvenir (纪念品). They steal handkerchief, they tear off buttons, and they even cut off pieces of unfortunate singer’s hair. Many singers have been forced to hide, and some who have not been so lucky as to escape have been stripped (剥) practically naked by their fans. A pop singer has to spend a lot of money on clothes because he must always look smart, or at any rate, different. He must have a luxurious (豪华的) car. And most importantly, he must always keep smiling for the benefit of his public.

3 . Microsoft won’t renew the contracts (合同) for dozens of news production staff working at its MSN website and plans to use AI to replace them. The roughly 50 employees were informed that their services would no longer be needed beyond June 30.
The Microsoft spokesman said in a statement, “Like all companies, we analyze and make judgments on our activities and services on a regular basis. This can result in increased investment in some places and, from time to time, rearrangement in others. These decisions are not the result of the pandemic.”
MSN will use AI to replace the production work its journalists had been doing. That work includes using an automated system (自动化系统) to identify trending news stories from dozens of publishing partners and to help improve the content by rewriting headlines or adding better accompanying photographs or slide shows.
“I spend all my time reading about how automation and AI are going to take all our jobs — now it’s taken mine” one of the terminated contractors said. “But with fewer human beings to monitor the technology, AI may not be fully familiar with strict editorial guidelines and could end up letting through inappropriate stories.”
MSN has experienced a number of changes since its launch as Microsoft Network in 1995. Once it offered original content and links to news, weather and sports. In 2013, it rolled back original news content and began cutting employees. By 2014, it launched are designed version that partnered with other news sites, paying them to redistribute their content. Today, the news service relies entirely on those partnerships with no original news content of its own. Selecting and editing stories rather than actually generating them made it easier for MSN to increasingly rely on an automated editing system.

4 . China has set new rules limiting the amount of time children can play online games. The rules limit children to just three hours of online game playing a week. That is one hour between 8 p. m. and 9 p. m. on Friday, Saturday and Sunday most weeks.
Li Zhanguo has two children aged 4 and 8. Even though they do not have smartphones, they enjoy playing online games. Like many other parents. Li is happy with new government rules. But experts say it is unclear if such policies can help prevent addiction to online games. Children might just get addicted to social media instead. In the end, experts say, parents should be the ones to set limits and support good practice.
There has been a growing concern in China about gaming addiction among children. Government reports in 2018 found that about one in ten Chinese children were addicted to the Internet. The new rules are part of an effort to prevent young people from spending too much time on unhealthy entertainment. That includes what officials call the “irrational fan culture”
Under the new rules, the responsibility for making sure children play only three hours a day as largely on Chinese gaming companies like Net Ease and Ten cent. Companies have set up real-name registration systems to prevent young users from going past game time limits. They have used facial recognition technology to check their identities. And they have also set up a program that permits people to report what is against the law. It is unclear what punishments gaming companies may face if they do not carry out the policies. And even if such policies are performed, it is also unclear whether they can prevent online addiction.
A specialist treating Internet addiction expects about 20 percent of children will find ways to break the rules by borrowing accounts of their older relatives and find a way around facial recognition. In his opinion, short-video alps such as Douyin and Kuaishou are also very popular in China. They are not under the same restrictions as games.
1. When can children play games according to the new rules?| A．Between 8 p. m. and 9 p. m. On Friday. | B．Between 8 p. m. and 9 p. m. On Tuesday. |

5 . There’s a song in your head. You keep hearing it repeatedly. You can’t make it stop, and it’s driving you crazy! Has this happened to you? Maybe you have suffered from an earworm, which is a memory of a song.
Earworms are common. A study showed that 90 percent of people experience them. Why do we get earworms? According to neurologist Oliver Sacks, music affects us whether we pay attention to it or not. We’re surrounded by music all the time in our everyday lives. Sacks wonders if there is a higher incidence of earworms today because of all this music in our environment.
Research on the primary auditory cortex supports Sack’s ideas. The auditory cortex is the part of the brain that processes sound. It’s a short-term storage system for small amounts of auditory information. Some of this auditory information is forgotten, and some of it goes into long-term memory. However, songs appear to stay in the auditory cortex for a long time.
James Kellaris, a professor of marketing at the University of Cincinnati, thinks that only certain types of songs become earworms. These songs are repetitive, simple, and incongruous — something unexpected such as uneven rhythm. Your brain pays a lot of attention to a song like this, Kellaris says. Because it is repetitive and unusual, it stays longer in the auditory cortex. At that point, Kellaris believes, it becomes an annoying earworm.
Advertisers often use jingles — short songs that are easy to remember to promote sales. Advertisers want jingles to stick in people’s minds to keep them thinking about their products. It seems that advertisers have learned what Kellaris has found out in his research.
Is there any way to get rid of an earworm? Here are some tips Kellaris collected: replace the earworm song with another song, try to distract yourself by doing an intense activity such as exercising, or tell someone about your earworm. What if none of these strategies work? Then perhaps you should just sit back and try to enjoy the music in your head!

6 . ChatGPT has quickly become popular around the world because of its advanced conversational abilities. It can answer questions, do translations, give the main idea of articles and even write codes (代码) for a computer program. It is as good as a human inside a computer.
ChatGPT is making life very convenient. A time might come when people hand it some articles and it makes a well-made report. That could, however, mean job losses. After all, if a computer program can write codes, then it would make a programmer lose his job.
That may be a worry, but it is still too early to worry about that. ChatGPT has more advanced learning features, but it still follows the same technological way. Its biggest advantage lies in the ability to turn words into a language from an ocean of data, but it's still not that creative. AI can quickly draw a picture, but that picture will be based on pictures that it has seen. It can also write books about the future, but the books will be based on articles about the future that it has read.
In comparison, a human brain imagines the future and then tries hard to realize it. AI can imagine a future with faster spaceships, but it can't imagine a world of space as humans can.
So there is no need to worry too much. By being creative there will be plenty of chances for humans to win over AI.

7 . Gather together a couple of good friends and take a leisurely stroll through the streets — this is what many youngsters in China enjoy doing when they visit a new city.
To them, Citywalk means “roaming around the city” on foot. Participants can follow a distinctive urban route, soaking up the atmosphere, exploring old buildings, browsing boutique shops, sipping a cup of coffee, or indulging in authentic local snacks.
Citywalk can be a special guided trip for a small group of people, or simply a leisurely stroll for one or two to explore new areas, sticking to the key point: avoiding famous scenic spots and big crowds to gain a more inclusive experience of the places you visit. Besides interacting with a city, Citywalk provides young people with a new social scene, where they who share the same interests and ideas can easily make friends.
In China, the Citywalk trend is spreading from first-tier cities like Beijing and Shanghai to second and third-tier cities, encouraging more participants and event organizers to get involved. Some organizers invite folk culture researchers and enthusiasts to act as tour guides. Xiao Yiyi, a young entrepreneur in Changsha, recently launched six Citywalk routes in different cities on her social media account, with the aim of providing experiences for visitors to “walk in open-air museums”. Her Changsha route features more offbeat sights like historical architecture from the 19th century, artsy old alleys, and even a stop-off to sample the local spicy crayfish specialty.
Even though Citywalk is a relatively new phenomenon, it is offering a positive change to urban travelers as they can better choose the experiences based on their interests and needs. At the same time, Citywalk represents an opportunity for tour guides and travel service providers to offer a more tailored, professional service to meet with ever-changing market demands.

8 . Mark Bertram lost the tips of two fingers at work in 2018 when his hand became trapped in a fan belt. “It’s life-changing but it’s not life-ending,” he says. “Doing work is harder now. Everything is just a little different.”
After two surgeries and occupational therapy, Bertram decided to make light of his condition by asking Eric Catalano, a tattoo (纹身) artist, to create fingernail (手指甲) tattoos. The idea made everyone in the studio laugh — until they saw the final result. “The mood changed,” Catalano recalls from his Eternal Ink Tattoo Studio in Hecker, Illinois. “Everything turned from ridiculous to wow.”
When Catalano posted a photo of the tattoos, a pair of fingernails looking so real that no one could believe their eyes, he had no idea the image would eventually be viewed by millions of people around the world.
The photo pushed Catalano, 40, further into the world of paramedical tattooing. Now people with life-altering scars come from as far away as Ireland to visit his shop. Using flesh-toned inks and a needle, Catalano transforms his clients’ view of themselves.
Leslie Pollan, 32, a dog breeder in Oxford, Mississippi, was bitten on the face by a puppy in 2014. After undergoing countless surgeries to correct a scar on her lip but in vain, she ultimately turned to Catalano, who covered her lip scar, giving her back a piece of her confidence. Pollan says, “It made me have a different outlook on life.”
“Every time I see that emotion from my customers, I’m 100 percent sure this is something that I can’t stop doing.”

9 . Caviar (鱼子酱) is typically associated with sturgeons swimming in the Caspian Sea, but the Mexican version is made from the tiny eggs of ahuautle, an insect also known as “bird fly”. For Juan, a farmer, cultivating and collecting the tiny insect eggs known as ahuautle is a way of life. “It means tradition,” said Juan, one of the only six people known to still harvest ahuautle. They fear they may be the last.
The painstaking collection of “Mexican caviar” is threatened by the drying out of Lake Texcoco, development around the lakeshore and decreasing interest in the ingredient among younger generations. The dish’s survival is seen as an example of “community resistance”, similar to the way in which inhabitants around Lake Texcoco have managed to preserve other traditions, festivals and ceremonies.
For Juan, it’s hard. Dressed in shorts and rubber boots, Juan walks with an effort through the calf-high waters to collect pine branches he has pushed into the muddy lakebed the week before. The branches serve as an anchor for the bird-fly bugs to deposit their eggs. After about two hours, Juan has gathered a pile of sticks covered with thousands of bird-fly eggs. He returns to the edge of the lake to lay the sticks out to dry in the sun, which can take several hours or days, depending on the weather.
“Eating this is like revisiting the past,” said restaurant owner Guerrero, 61. He says the flavor of the ahuautle reminds him of his childhood. But Guerrero acknowledges that “Mexican caviar” is at risk of disappearing because younger generations aren’t familiar with the dish, and ever-fewer people harvest it in the scarce remaining lakes where it is found.
Edday, an entomologist (昆虫学家), said there are more than 430 species of eatable insects in Mexico. He said native people living around the lakes adopted the insect eggs as a source of protein because prior to the Spanish conquest of 1521, they had few domesticated (驯养的) animals. But now, Edday said, the dish “is associated with the countryside, perhaps with poverty, as if it were an undesirable protein.”
1. What is a cause of the decline of the dish in Mexico?| A．Expansion of the lakeshore. | B．Difficulty in cooking the dish. |
| C．Young diners’ lack of interest. | D．Overexploitation of the ingredient. |
| A．To help collect ahuautle. | B．To help dry sticks in the sun. |
| C．To protect the edge of the lake. | D．To be an anchor for farmers working there. |
| A．Why ahuautle is a good source of protein. |
| B．Why Mexicans should give up eating insects. |
| C．Why ahuautle was popular in the past but not now. |
| D．Why Mexicans prefer to eat insects rather than animals. |
| A．A popular traditional pet in Mexico. | B．A way of harvesting ahuautle easily. |
| C．A current social phenomenon in Mexico. | D．An attempt to preserve Mexican tradition. |
10 . Search online “work too much” and you’ll get screenfuls of information about the harmful medical, mental and social consequences of spending too much time on the job. However, under current circumstances, the old saying “All work and no play makes Jack a dull boy.” should be “makes Jack a dead boy.”
A latest study by W.H.O. says that working 55 or more hours a week is a “serious health risk”. It estimates that long working hours led to 745,000 deaths worldwide in 2016, a 29 percent increase over 2000. Men accounted for 72 percent of the deaths; the worst concentrations were in the Western Pacific and Southeast Asia, and particularly among 60 to 79-year-olds who had worked long hours after the age of 45.
These figures make long working hours the biggest work-related health risk of all. Risk of a stroke rises by 35 percent and of deadly heart disease by 17 percent for those who can’t or won’t stop working, compared with people who work 35 to 40 hours a week. The pandemic, and especially remote work, has created new opportunities to work too hard.
The W.H.O. director-general, Dr. Tedros Adhanom Ghebreyesus, noted that teleworking has blurred the line between work and home and that people who have survived layoffs (裁员) at struggling businesses have ended up working longer hours. One survey found an overwhelming majority of American employees have shortened, postponed or canceled vacations during the pandemic.
The red flags about overwork have been waving for years all around the world. Exhaustion has been identified as a factor in industrial disasters like the BP oil refinery explosion in Texas City in 2005 and the nuclear accident at Three Mile Island. In Japan, long working hours are so common that “karoshi,” translated as “death by overwork”, is a legally recognized cause of death.
So, working less is a matter of life and death, isn’t it?
