2 . As plastic waste increases rapidly around the world, an essential question remains unanswered: What harm, if any, does it cause to human health?

A few years ago, as microplastics began turning up in the organs of fish and shellfish, the concern was focused on the safety of seafood. Shellfish were a particular worry, because in their case, unlike fish, we eat the entire animal — stomach, microplastics and all. In 2017, Belgian scientists announced that seafood lovers could consume up to 11,000 plastic particles (粒子) a year by eating mussels (贻贝), a favorite dish in that country.

By then, however, scientists already understood that plastics continuously fragment small pieces in the environment, tearing over time into fibers even smaller than a strand of human hair — particles are so small that they easily fly in the air. A team at the U.K.’s University of Plymouth decided to compare the threat from eating polluted wild mussels in Scotland to that of breathing air in a typical home. Their conclusion: People will take in more plastic by breathing in or taking tiny, invisible plastic fibers floating in the air around them—fibers from their own clothes, carpets, and soft covering on furniture — than they will by eating the mussels.

So, it wasn’t much of a surprise when, in 2022, scientists from the Netherlands and the U.K, announced they had found tiny plastic particles in living humans, in two places where they hadn’t been seen before: deep inside the lungs of surgical patients, and in the blood of unknown donors. Neither of the two studies answered the question of possible harm. But together they signaled a shift in the focus of concern about plastics toward the cloud of dust particles in the air, some of them are so small that they can get into deep inside the body and even inside cells, in ways that larger microplastics can’t.

Dick Vethaak, a professor of ecotoxicology (生态毒理学), doesn’t consider the results alarming, exactly—“but, yes, we should be concerned. Plastics should not be in your blood.” “We live in a multi-particle world,” he adds, referring to the dust, pollen (花粉), and smog that humans also breathe in every day. “The trick is to figure out how much plastics contribute to that particle burden and what does that mean.”

4 . As cities balloon with growth, access to nature for people living in urban areas is becoming harder to find. If you’re lucky, there might be a pocket park near where you live, but it’s unusual to find places in a city that are relatively wild.

Past research has found health and wellness benefits of nature for humans, but a new study shows that wildness in urban areas is extremely important for human well-being.

The research team focused on a large urban park. They surveyed several hundred park-goers, asking them to submit a written summary online of a meaningful interaction they had with nature in the park. The researchers then examined these submissions, coding (编码) experiences into different categories. For example, one participant’s experience of “We sat and listened to the waves at the beach for a while” was assigned the categories “sitting at beach” and “listening to waves.”

Across the 320 submissions, a pattern of categories the researchers call a “nature language” began to emerge. After the coding of all submissions, half a dozen categories were noted most often as important to visitors. These include encountering wildlife, walking along the edge of water, and following an established trail.

Naming each nature experience creates a usable language, which helps people recognize and take part in the activities that are most satisfying and meaningful to them. For example, the experience of walking along the edge of water might be satisfying for a young professional on a weekend hike in the park. Back downtown during a workday, they can enjoy a more domestic form of this interaction by walking along a fountain on their lunch break.

“We’re trying to generate a language that helps bring the human-nature interactions back into our daily lives. And for that to happen, we also need to protect nature so that we can interact with it,” said Peter Kahn, a senior author of the study.

5 . In the early 1990s, Eric Domb, a highly successful lawyer, came up with the idea of building a bird park. His father-in-law ________ the idea in the beginning, but when the ________ started to make shape he backed out. Domb thus had to ________ money from former clients, his two brothers and father as well as a bank to build a zoological park known as Pairi Daiza.

After the park opened in 1994, his inexperience led to many ________, but he pushed on with his venture (冒险). By 2000, the park was turning a profit, and Domb’s ambitions were ________. The park needed more than birds, he believed, and other creatures and cultural gardens would help turn it into something ________.

Since his childhood he has been fascinated by Chinese ________. In 2006, he built the first Chinese garden, Dream of Han Wu Di in his zoo. It was said to be the largest Chinese garden in Europe. Domb kept ________ new elements. It finally took more than six years to complete the project.

Domb felt ________ by the joint panda breeding program. Domb and his people spent the following months ________ building giant panda houses with no guarantee that Pairi Daiza would be fortunate enough to ________ giant pandas. The huge enclosure built includes a pool, cave and ________ plantation.

Now, Domb is eager to tell how he ________ a pair of giant pandas, Xing Hui and Hao Hao in February 2014. The sense of ________ is all the more profound in that Pairi Daiza is one of the few private zoos outside China to ________ giant pandas.

French disaster epic Notre-Dame on Fire hits Chinese big screen

This April marks the     1     (four) anniversary of Notre-Dame in Paris being engulfed by the biggest blaze in its history.

NotreDame on Fire, now in Chinese cinemas, is a disaster epic     2     veteran French filmmaker Jean-Jacques Annaud, who also helmed Wolf Totem(2015), a drama film     3     (adapt) from Chinese writer Jiang Rong’s eponymous novel. The film made its China premiere on April 6 in Beijing in the presence of France’s Minister of Culture Rima Abdul Malak and the director.

Presenting a blow-by-blow recreation of the gripping events that     4     (happen) on April 15, 2019 when the fire at the French medieval catholic cathedral rocked France and shocked the whole world, Annaud’s new film hails the heroic people who put their lives on     5     line to accomplish the awe-inspiring rescue. Annaud unveiled the filming details of the film to the audience     6     (attend) the China premiere.

“It was a     7     (danger) movie. The actors were actually very close to the extremely violent fire, 1,200-degree Fahrenheit fire. There are very few digital special effects. Almost all of what you have seen are     8     (identical) reconstructed sets that I set on fire,” he said.

“When I saw this movie in Paris last year, it took me a few hours     9     I could breathe and walk normally on the street,” said Malak at the film’s China premiere.

The French minister announced that 2024 will be the France-China Year of Culture and Tourism and she invited Chinese tourists to travel to France for the occasion, especially to see the Notre-Dame cathedral in Paris,     10     , after almost six years of extensive renovations, is scheduled to reopen to the public in December of the same year.

8 . The humble honey bee is responsible for up to 80 per cent of plant pollination (授粉) worldwide. But population numbers are in steep decline because of habitat loss, pesticides and pollution — threatening our food security. One startup has identified a potential solution — the common hoverfly (食蚜蝇).

UK-based designer Tashia Tucker has created an AI-based technology called Olombria, which encourages hoverflies to increase their pollination levels to match that of bees. Although flies perform approximately 30 percent of the world’s pollination, they aren’t as efficient as bees, often getting distracted and “wandering off” before they can carry pollen between plants.

Olombria is a solution — an AI pollination system that encourages hoverflies to pollinate targeted sites when the plants are in bloom (鲜花盛开). The system consists of sensors, cameras and chemical signaling devices placed within specified areas of an orchard or field. It starts by collecting data on the level and diversity of pollinators in a grower’s field as well as pollination effectiveness.

This information, combined with other environmental data — time, the location and temperature, allows the system to paint an overall picture of pollinator health and then take action. “We first provide that baseline data,” Tucker explains, “so we have an understanding of where there are deficiencies (缺乏) and areas that need to be improved, and then we distribute our natural chemical signaling from the device.”

Depending on what areas of an orchard need pollinating, Olombria’s AIcloud system triggers chosen devices to release organic chemicals that encourage hoverflies to move towards those specific areas. “The chemicals do not change what the flies would naturally do, but target their location and increase the amount of pollen that they’re picking up and transferring,” Tucker explains.

The hoverflies work in cooperation with the bees and, through Tucker’s research, she’s found that the hoverflies even encourage bees to become more efficient pollinators. “There’s a bit of competition; it focuses the bees’ pollination as there’s another insect in the area,” says Tucker.

As a designer, Tucker initially designed Olombria’s device to look like a fruit to reflect the ethos (气质) of the design. “When I started working with farmers, I knew I needed to design the technology to be strong enough to stay out in the field and in various weather conditions,” says Tucker. Since then, Tucker has changed the design and is exploring what colors work well with insects. “As we start to streamline the technology, it is becoming more refined,” Tucker explains. “As an AI system, it’s great, as it’s just getting smarter as the technology develops.”

It was a sunny summer morning, the breeze blowing gently. As planned, Jackson took a trip into the remote wilds near Olom Village, in the Sakha Republic, Russia. His four-year-old daughter, Karina, found him leaving and wanted to follow him to give her dad a surprise. She slipped out of the house, with nobody realizing it, even Jackson.

Unfortunately, she walked too slowly on her way and soon she was lost in the vast, dangerous Siberian wilderness. Luckily for her, her dog, Naida, followed Karina just as the girl followed her father. The two suddenly found themselves walking with no one in sight, drifting away from their home as the hours went by.

Night fell. Karina’s father returned home, and it didn’t take long after that for the whole family to realize what had happened. They couldn’t find Karina anywhere. They turned to the police for help immediately. And they took action at once in search of the lost girl.

A whole week had gone by and there was no progress of the rescue in sight. The whole family was stuck in desperation, but Karina’s mum never lost hope. “Many stopped believing that she was alive, but as a mother I felt that she would be found soon.”

In fact, Karina did survive. Although Siberia is an extremely dangerous place even for otherwise fit adults due to its wildlife and climate, she made it. She survived by eating wild fruits and drinking water from nearby rivers, and she faced the freezing nighttime temperatures by cozying up in a bed of grass. Naida did its best too, scaring away the wild animals and keeping each other warm by sleeping close together at night.

After nine days struggling to survive, scared and alone, Karina could only be grateful about one thing: her good friend was by her side. Naida gave its strength, and actively helped the four-year-old to stay alive for that long.
