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 . Going for a picnic is a good experience to be in nature, but it’s terrible to have a picnic that will do harm to the environment. Here are some ways to keep your picnic green.
Use reusable plates and cups. You don’t need to wash disposable (—次性的) plates and cups because they pollute the environment. It’s greener and cheaper to bring metal plates and cups from home. After the picnic, you can take them home and wash them.
Try to buy food from local farmers’ markets. In general, if you bring less food for your picnic, you’ll create less pollution.
Try to have an all-vegetarian picnic. Modern production of meat uses lots of energy and creates lots of pollution.
Instead of driving, ride a bike or walk to the park. If the park you want to visit is too far from your home, you can take public transportation like buses or subways.
After your picnic, remember to pick up all your trash. Try to keep the picnic area clean. If possible, try not to create any trash at all and reuse whatever you can.

3 . Technology seems to discourage slow, immersive reading. Reading on a screen tires your eyes and makes it harder for you to keep your place. Online writing tends to be more skimmable than print. The cognitive neuroscientist Mary Walt argued recently that this “new norm” of skim reading is producing “an invisible, game-changing transformation” in how readers process words. The neuronal circuit (回路) that sustains the brain’s capacity to read now favors the rapid absorption of information.
We shouldn’t exaggerate this danger. All readers skim. From about the age of nine, our eyes start to bounce around the page, reading only about a quarter of the words properly, and filling in the gaps by inference. So far, the anxieties have proved to be false alarms. “Quite a few critics have been worried about attention spans lately and see very short stories as signs of cultural decline,” the American author Selvin Brown wrote. “No one ever said that poems were evidence of short attention spans.”
And yet the Internet has certainly changed the way we read. For a start, it means that there is more to read, because more people than ever are writing. And digital writing is meant for rapid release and response. This mode of writing and reading can be interactive and fun. But often it treats other people’s words as something to be quickly harvested as fodder (素材) to say something else. Everyone talks over the top of everyone else, desperate to be heard.
Perhaps we should slow down. Reading is constantly promoted as a social good and source of personal achievement. To a slow reader, a piece of writing can only be fully understood by immersing oneself in the words. and their slow comprehension of a line of thought,
The human need for this kind of deep reading is too tenacious for any new technology to destroy. We often assume that technological change can’t be stopped and happens in one direction, so that older media like “dead-tree” books are kicked out by newer, more virtual forms. In practice, older technologies can coexist with new ones. The Kindle has not killed off the printed book any more than the car killed off the bicycle. We still want to enjoy slowly formed ideas and carefully-chosen words. Even in a fast-moving age, there is time for slow reading.

4 . You may have read that light coming into your eyes sets the body’s clock. Similarly, food changes the clocks in tissues in your liver, muscles, and fat. Human beings developed to eat only during daylight, which lasted 12 hours. That meant we didn’t eat for 12 hours a day. Sticking to that plan may help you stay healthier as well as thinner. However, it’s a surprisingly bad idea to ignore breakfast, eat lunch or dinner late, eat a big bedtime snack, or eat in the middle of the night.
In a study with 776 participants, people who ignored breakfast were 80 percent more likely to have obesity (肥胖症). People who ate lunch after 12:30 (or dinner after 21:00) were 60 percent more likely to have those extra pounds. That was true for both men and women at different ages and regardless of other factors that affect weight including your diet and exercise habits.
Odd hours seem to contribute to uncontrollable eating. When you eat late at night, you tend to eat more. Perhaps driven by hormone (荷尔蒙) increases, we long for sweeter, saltier food at night, research suggests. In one study, night eaters ate about 300 more calories each day.
“Eating late in the day aggravates reflux, writes Jamie A. Koufman, who specializes in voice disorders and acid reflux (胃酸倒流). Many of my patients find that eating late makes them suffer more from their allergies and diabetes symptoms,” he says. “Give your stomach at least three hours to digest before sleeping,” advises Jonathan Aviv, another specialist in acid reflux.
Eating breakfast late may also increase your breast cancer risk by about 17 percent for every hour you delay, according to a study of nearly 1,200 women with breast cancer in Spain, compared to more than 1,300 women who didn’t develop breast cancer. If you eat late at night, another research suggests, you may up the chance of breast cancer occurrence. While researchers work out the details of how our body clocks affect digestion and their downstream effects, one point is clear: Early is better.

5 . Christ Mocked, by the Florentine master Cimabue, was sold at auction(拍卖)for €24 million in 2019. But the Chilean buyers never got to include the work in their collection because the French government refused to give it an export licence.
Ministers declared the painting a national treasure, officially giving the Louvre 30 months to raise the funds for its purchase. The Louvre recently reached an agreement with the owners.
Laurence des Cars, the president of the Louvre, said it was a “great joy” to have acquired the painting, which “constitutes a crucial landmark in the history of art”. The museum did not say how much it had paid, nor who had sold the painting, which will be exhibited in 2025.
The painting was spotted four years ago by Philomene Wolf, an auctioneer, when she was asked to assess the content s of a house that was being cleared. The owner, in her nineties, thought it was a painting from Russia of no value and was preparing to put it in the dustbin.
Wolf was struck by its quality and guessed that it could be Italian. Experts using modern technology confirmed that it was by Cimabue, who is widely regarded as having opened the gateway to Renaissance art. It is believed to date from 1280. Christ Mocked is one of about 15 known Cimabue’s works.
The Louvre launched an appeal on Tuesday for donations to buy another painting, The Basket of Wild Strawberries by Jean Simeon Chardin, the 18th-century French still life(静物画)master. The work, which was first exhibited in 1761, was in a private collection from the 19th century until last year, when it was sold for €24.3 million to an American art museum at an auction in Paris.
Luckily, many groups and individuals donated two-thirds of the sum. The museum must pay the remaining € 8 million and is hoping that members of the public will help to ease the burden by responding to its appeal, which aims to raise € 1.3 million.

6 . The world’s most famous tire (轮胎) graveyard (坟地) of 42 million tires in the sands of Kuwait is finally being cleaned up and recycled. This news in itself would be a major relief to locals who have to suffer from the clouds of black smoke arising during fires. But the government isn’t stopping there. They are aiming to create a green city of 25,000 homes in line with a post-oil Persian Gulf, with a focus on sustainability and tourism.
The first step is to clear the ground. The Salmiya area, nicknamed “Rubber (橡胶) Mountain”, is formed from hundreds of small mountains of spent tires — a reaction from the one million cars which were added to Kuwait’s roads over the decade.
EPSCO Global General Trading recycling company has opened a recycling plant for the tires, where they’ve been collected, sorted, cut up, and pressed into other materials like rubbery coloured flooring tiles (铺地砖). The plant opened in January of 2021, and can recycle up to 3 million tires a year. The recycled material is then exported out to nearby gulf neighbours and Asia. In the place of the tires will be South Saad Al-Abdullah City, a green city characterizing a new era in the Middle-Eastern country.
Spent tires are a major environmental problem worldwide due to the room they take up and the chemicals they can release.
“We have moved from a difficult stage that was characterized by great environmental risk,” says Oil Minister Mohammed al-Fares. “Today the area is becoming clean and all tires are being removed to begin the launch of the project of Saad Al-Abdullah city.”
Expected to cost €3.3 billion and require 30 years to complete, the city hopes to feature green technology, probably like the kind one can see in other cities on the Persian Gulf, both existing and not. Saudi Arabia is planning to build a zero-emissions, car-less future city that’s centered around access to big data rather than water or crops.

7 . As much as 80 percent of premature (早期的) heart disease is preventable by making specific lifestyle choices. Some strategies, such as exercising and managing weight, are well known.
Get eight hours of sleep. “When you're not rested, everything that happens in your life is a lot more stressful,” says Dr. Arya Sharma, founder of the Canadian Obesity Network. If we lack sleep, our bodies also have more difficulty controlling blood pressure, inflammation and glucose levels.
Avoid polluted air.
Treat depression. “Depression can affect the way we behave,” says Dr. Arya Sharma. Not only are we more likely to drink too much alcohol and to avoid exercise,
| A．Avoid loneliness. |

8 . The term “Hudson River school” was applied to the foremost representatives of nineteenth-century North American landscape painting. Apparently unknown during the golden days of the American landscape movement, which began around 1850s and lasted until the late 1860s, the Hudson River school seems to have emerged in the 1870s as a direct result of the struggle between the old and the new generations of artists each to assert its own style as the representative American art. The older painters, most of whom were born before 1835, practiced in a mode often self-taught and monopolized by landscape subject matter and were securely established in and fostered by the reigning American art organization, the National Academy of Design.
The younger painters returning home from training in Europe worked more with figural subject matter and in a bold and impressionistic technique; their prospects for patronage in their own country were uncertain, and they sought to attract it by attaining academic recognition in New York. One of the results of the conflict between the two factions was that what in previous years had been referred to as the American, native, or, occasionally New York school — the most representative school of American art in any genre — had by 1890s become firmly established in the minds of critics and public alike as the Hudson River school.
The sobriquet was first applied around 1879. While it was not intended as flattering, it was hardly inappropriate. The Academicians at whom it was aimed had worked and socialized in New York, the Hudson’s port city, and had painted the river and its shores with varying frequency. Most important, perhaps, was that they had all maintained with a certain fidelity a manner of technique and composition consistent with those of America’s first popular landscape artist, Thomas Cole, who built a career painting the Catskill Mountain scenery bordering the Hudson River.
A possible implication in the term applied to the group of landscapists was that many of them had, like Cole, lived on or near the banks of the Hudson. Further, the river had long served as the principal route to other sketching grounds favored by the Academicians, particularly the Adirondacks and the mountains of Vermont and New Hampshire different ways.

9 . We’ve all been there: in a lift, in line at the bank or on an airplane, surrounded by people who are, like us, deeply focused on their smartphones or, worse, struggling with the uncomfortable silence.
What’s the problem? It’s possible that we all don’t have enough conversational ability. It’s more likely that none of us start a conversation because it’s embarrassing and challenging, or we think it’s annoying and unnecessary. But the next time you find yourself among strangers, consider that small talk is worth the trouble. Experts say it’s a valuable social practice that leads to big benefits.
It is easy to consider small talk as unimportant, but we can’t forget that deep relationships wouldn’t even exist (存在) if there weren’t casual conversations. Small talk is the grease (润滑剂) for social communication, says Bernardo Carducci, director of the Shyness Research Institute at Indiana University Southeast. “Almost every great love story and each big business deal begins with small talk,” he explains. “The secret to successful small talk is learning how to connect with others, not just communicate with them.”
In a 2014 study, Elizabeth Dunn, professor of psychology at UBC, invited people to a coffee shop. One group was asked to interact with its waiter, the other, to speak only when necessary. The results showed that those who chatted with their server reported obviously higher positive feelings and a better coffee shop experience. “It’s not that talking to the waiter is better than talking to your husband,” says Dunn. “But interactions with peripheral (边缘的) members of our social network is important for our happiness and health.”
Dunn believes that people who reach out to strangers feel a greater sense of belonging, a link with others. Carducci believes developing such a sense of belonging starts with small talk. “Small talk is the basis of good manners,” he says.

10 . We often think about relationships on a scale from positive to negative. We are drawn to loving family members, caring classmates and supportive mentors. We do our best to avoid the cruel uncle, the playground bully and the jerk boss.
But the most harmful relationships aren’t the purely negative ones. They’re the ones that are a mix of positive and negative. We often call them frenemies, supposed friends who sometimes help you and sometimes hurt you. But it’s not just friends. It’s the in-laws who volunteer to watch your kids but devalue your parenting. The manager who praises your work but denies you a promotion.
Groundbreaking research led by the psychologists Bert Uchino and Julianne Holt-Lunstad shows that ambivalent (矛盾情绪的) relationships can be damaging to your health — even more than purely negative relationships.
Even a single ambivalent interaction can cause harm. In one experiment, people talked about controversial (具有争议性的) topics in front of a friend who offered feedback. The researchers had randomly assigned the friend to give ambivalent or negative comments. Receiving mixed feedback caused higher blood pressure than pure criticism. “I would have gone about the topic differently, but you’re doing fine” proved to be more distressing than “I totally disagree with everything you’ve said.”
The evidence that ambivalent relationships can be bad for us is obvious, but the reasons can be harder to read — just like the relationships themselves.
One reason is that ambivalent relationships are unpredictable. With a clear enemy, you put up a shield when you cross paths. With a frenemy, you never know whether Dr. Jekyll or Mr. Hyde is going to show up. Feeling unsure can break the body’s calming system and activate a fight-or-flight response. It’s unsettling to hope for a hug while also preparing for a likely quarrel.
Another factor is that unpleasant interactions are more painful in an ambivalent relationship. It’s more distressing to be let down by people you like sometimes than by people you dislike all the time. When someone stabs you in the back, it stings more if he’s been friendly to your face.
1. Which of the following can be considered as a frenemy?| A．Your neighbor’s kid who advises you to study hard but kill his own time. |
| B．Your classmate who admires your hard work at first, but doubts your intelligence later. |
| C．Your mother’s friend who encourages you to spend more time on homework but less on smart phones. |
| D．Your father’s colleague who proposes you to do a reasonable amount of homework while ensuring enough sleep. |
| A．Upsetting. | B．Satisfying. | C．Inspiring. | D．Confusing. |
| A．The negative impact of ambivalent interactions is strong. |
| B．Ambivalent relationships have a long-lasting effect on your well-being. |
| C．The common cause of high blood pressure is ambivalent relationship. |
| D．Interactions in ambivalent relationships are more painful than those in negative ones. |
| A．Negative relationships are bad for health. | B．Ambivalent relationships are unpredictable. |
| C．Ambivalent Relationships are the most harmful. | D．Positive relationships are better than negative ones. |
