1 . You’ve heard that plastic is polluting the oceans — between 4.8 and 12.7 million tonnes enter ocean ecosystems every year. But does one plastic straw or cup really make a difference? Artist Benjamin Von Wong wants you to know that it does. He builds massive sculptures out of plastic garbage, forcing viewers to re-examine their relationship to single-use plastic products.

At the beginning of the year, the artist built a piece called “Strawpocalypse,” a pair of 10-foot-tall plastic waves, frozen mid-crash. Made of 168,000 plastic straws collected from several volunteer beach cleanups, the sculpture made its first appearance at the Estella Place shopping center in Ho Chi Minh City, Vietnam.

Just 9% of global plastic waste is recycled. Plastic straws are by no means the biggest source (来源) of plastic pollution, but they’ve recently come under fire because most people don’t need them to drink with and, because of their small size and weight, they cannot be recycled. Every straw that’s part of Von Wong’s artwork likely came from a drink that someone used for only a few minutes. Once the drink is gone, the straw will take centuries to disappear.

In a piece from 2018, Von Wong wanted to illustrate (说明) a specific statistic: Every 60 seconds, a truckload’s worth of plastic enters the ocean. For this work, titled “Truckload of Plastic,” Von Wong and a group of volunteers collected more than 10,000 pieces of plastic, which were then tied together to look like they’d been dumped (倾倒) from a truck all at once.

Von Wong hopes that his work will also help pressure big companies to reduce their plastic footprint.

Researchers say they have found microplastics (微塑料) -tiny pieces of plastic that come as a result of the disposal of industrial waste-deep in the lungs of living     1     (human) for the first time.

The research, which     2     (publish) in the journal Science of the Total Environment last week, is the first study     3     (identify) the plastics in the lungs of living people. The plastics have     4     (previous) been found in human blood, waste and in the depths of the ocean.

In the study, researchers     5     (collect) lung tissue from surgical procedures on patients as part of their routine medical care. Researchers identified 12 types of microplastics,     6     are commonly found in bottles, packaging, and clothing, along with other manufacturing processes.

The study notes     7     “increasing concern” with the harm that could come with swallowing and breathing in microplastics.

The world produces about 300 million metric tons of plastic a year and about 80% ends     8     in landfills and other parts of the environment. Microplastics can range from 10 nano-meters-    9     (small) than the human eye can see-to 5 millimeters in diameter, about the size of the eraser on the end of a pencil. Researchers have found them     10     (float) in the air, in tap or bottled water, and in the sea or soil.

5 . Recycling is a great way of doing your bit for the environment and helping to protect the earth’s precious resources. However, a new study has revealed that our desire to be sustainable maybe doing more harm than good. According to waste company Biffa, this is because of “wish-cycling” — assuming that items such as disposable coffee cup sand pizza boxes will be recycled if put in the recycling bin. In fact, pollution from those items or other non-recyclables can result in recyclable items that have been put in the correct bin going to landfill. David Heaton, a business director at Biffa, said: “Pollution happens when items are disposed of in the wrong bins or haven’t been cleaned before being recycled.”

Experts at Biffa analyzed the amounts of non-target and non-recyclable materials that entered UK material recycling facilities between 2016 and 2020. It was found that, in 2016, the average pollution rate of recycling waste was 13.4 percent, rising over four years to 17 percent by the end of 2020. This shows that, even as people are becoming more eco-conscious, wish-cycling is increasing both in households and businesses.

The Biffa experts say that one of the best ways to prevent pollution of recycling is to clean recyclable waste before putting it in the bin. They suggest cutting off the top of old pizza boxes and only recycling that part to avoid pollution from the grease (油脂). Check the on-packaging recycling label to check it can actually be recycled When it comes to plastics, Biffa recommends checking the resin code, the number in the plastic triangle, to know whether it should go in the recycling bin. In general, resin codes 1, 2, 4 and 5 are recyclable, while 3, 6 and 7 are not. Larger items, like electronics, furniture and batteries, can also be recycled but often can not go in household recycling bins as they need specialist separating. These will need to be taken to recycling centers or sustainable waste management companies.

“It’s vital as a nation that we get better at effective ‘pre-cycling’— sorting waste correctly before collection to reduce pollution rates,” added Mr. Heaton.

6 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

The World Health Organization (WHO) has announced a shocking finding about the air we breathe. It has found that almost everyone on Earth breathes unhealthy air. The WHO made     1    (it) air quality update ahead of World Health Day on April 7. The update reported that 99 per cent of the world’s population breathes air     2     goes beyond WHO air quality limits. It looked at data from over 6,000 cities in 117 countries. People     3    (live) in lower- and middle-income countries breathe the poorest-quality air. Millions of people die in these countries because of pollution-related diseases. The WHO said: “After surviving a pandemic, it is unacceptable to still have 7 million preventable deaths due     4     air pollution.”

The WHO said its report highlighted the need to move away from fossil fuels. It asked governments to do more     5     (reduce) levels of air pollution. It said: “Current energy concerns highlight the importance of speeding up the transition to cleaner and     6    (healthy) energy systems.” It added that high gas prices, energy     7    (secure), the dangers of air pollution, and climate change mean the world must be less dependent on fossil fuels. The WHO report     8    (include) many recommendations for change. One of these is     9     use of clean energy for cooking, heating and lighting. Another is to “build safe and affordable public transport systems and pedestrian- and cycle-friendly     10    (network)”.

7 . Conifers (针叶树) are generally better than broad-leaved trees at purifying air from pollutants. But deciduous (落叶的) trees may be better at taking in particle-bound pollution. A new study led by the University of Gothenburg shows that the best trees for air purification depend on the type of pollutants involved.

Trees and other greener in cities provide many benefits that are important for the well-being of residents. Leaves and needled on trees filter air pollutants and reduce exposure to poisonous substance in the air. But which trees purify the air most effectively? Researchers from the University of Gothenburg have collected leaves and needle from eleven different trees growing in the same place in the Gothenburg Botanical Garden (GBG) to analyse which cub-stances they have absorbed.

“This tree collection provided a unique opportunity to test many different species of trees with similar environmental conditions and exposure to air pollutants,” said Jenny Klingberg, a researcher of the GBG

A total of 32 different pollutants were analysed, some of which are bound to articles of various sizes. Others are gaseous. This project has focused on paths (多环芳烃). In cities, traffic is the biggest source of these pollutants, which are released due to incomplete burning in engines.

“Our analysis show that different species of trees have different abilities to absorb air pollutants. Conifers generally absorb morn gaseous paths than broad-leaved trees. Another advantage of conifers is that they also act as air purifies in winter, when air pollution is usually at its highest,” said Jenny Klingberg.

“This study contributes to improving our understanding of the ability of trees to clean the air and which species are best at absorbing air pollutants,” said Jenny Klingberg. This known-edge is important for urban planning when designing sustainable cities. While trees and green-era can contribute to better air quality in cities, at the end of the day, the most important measure is to reduce emissions.

8 . Around the world, people are realizing the significant problems caused by plastic waste. In the last 65 years, we have become increasingly dependent on plastic. It’s easy to understand why: it’s cheap to produce, light — therefore easy and cheap to transport — and incredibly strong and durable.     1    

One popular solution to the problem is to prohibit single use plastics. In the British supermarkets, shoppers are encouraged to make more environmentally-friendly choices in packing and transporting their food.     2     Some governments have even promised to ban the use of single-use plastic altogether by the not-too-distant future.

However, such plans may not be beneficial to eliminate (消除) the use of single-use plastic altogether.     3     This is not just because of its low cost. It’s also because infection and cross-contamination (交叉感染) are minimized. Plastic packaging is also crucial in the food industry. It ensures that food is safe for consumers.

Another issue is that alternative materials to plastic are often more environmentally harmful than plastic. Take paper bags, for example.     4     The process requires cutting trees, the emission of greenhouse gases and the production of poisonous chemical waste. Even more pollution is created when paper bags break down.

Clearly there is a need to reduce plastic waste and its impact on the environment.     5     Industries that rely on single-use plastics for people’s health and safety must be considered. Moreover, alternative materials must be evaluated strictly regarding their own environmental impact.

A．But it’s these advantages that also make it so harmful.

B．They are very fragile and rarely reusable, unlike plastic.

C．One of the fields where single-use plastic has a vital role is medicine.

D．However, simply banning their single use may not be the best option.

E．It also boosts the local economy and save costs in managing littering and waste.

F．Bans on single-use plastic items like drinking straws are also coming into place.

G．According to a research, they require four times more energy when produced than a plastic bag.

9 . A new UK-based study on the effects of artificial light on local insect populations found that light pollution from street lamps disturbs insect behavior, leading to an overall loss of insects.

“We found that street lighting strongly reduced moth (飞蛾) population compared with unlit sites... and affected moth development,” the study stated.

The study’s results apply to a localized level and cannot be used to determine whether national-level populations are declining due to light pollution. However, it adds further weight to existing research on how light pollution affects ecosystems and biodiversity hotspots and highlights the need to shift to alternatives in artificial light that would tone down these effects.

The effects on insect populations are wide-ranging. More specifically, artificial light affects how moths lay their eggs and puts them at a higher risk of being spotted by predators (捕食性动物). It also affects moths’ feeding behavior, which subsequently leads to declines in their population too. Light pollution thus joins a host of factors, such as climate change and deforestation, as one of the determinants of insect population decline.

While previous studies examined the effects of lighting on bats and other vertebrates, this study focused on their prey—creatures lower down in the food chain—and, as a result, complementing (补充) previous studies. Therefore, the study is concerning because it suggests an alarming loss of insects caused by artificial light, which will have far-reaching consequences for all the wildlife and ecosystems that depend on them.

Moreover, white light-emitting diodes (LEDs) were found to have the worst impact on local insects and ecosystem processes. The researchers thus call for shifting away from white LEDs or employing processes such as motion sensors to make the lights less bright and changing colors and filters to avoid the negative impacts. If the findings of the study are anything to go by, local insect ecosystems will suffer considerable consequences- which will, in turn, affect the wildlife that depends on them and, ultimately, could perhaps even upset agricultural balances.

10 . Carried by the wind, dust particles (微粒) from places such as the Sahara Desert can float halfway around the world before settling to the ground. As the plastics abandoned by humans break down into tiny pieces in the environment, they, too, travel through the atmosphere. Now scientists are a step closer to understanding how these microplastics travel in the globe — both locally and on long-distance flights.

Researchers spent more than a year collecting microplastics from 11 national parks and wilderness areas in the western U.S. They examined the particles that settled on dry days and those that fell along with rain or snow. In addition to making clear how microplastics move around, the results, published on Thursday in Science, reveal the seriousness of the problem: more than 1 million kilograms of microplastics — the weight of 120 million to 300 million plastic water bottles — fall on protected lands in the country’s western region each year.

The new findings add to scientists’ concern over microplastic pollution’s potential impacts on the environment and human health. “We’re not supposed to breathe in this material,” says Steve Allen, a microplastics researcher at the University of Strathclyde in Scotland, who was not involved in the new study. “Plastics in the environment “carry all sorts of pesticides (农药), heavy metals and all the other chemicals that we’ve made over time,” he adds. “They’re going to carry them directly into our lungs.”

Since their discovery in oceans in the 1970s, microplastics — which can be as large as a grain of rice or smaller than a particle of dust — have been found nearly everywhere researchers have looked: in cities, in Arctic snow, on remote mountaintops. Their presence in areas distant from the place where human live has pointed to them being carried by winds.

1. What do the scientists further understand now?

A．Why Sahara Desert is expanding to the south of Africa.

B．How plastic particles travel on the wind.

C．Why it is hard for plastics to break down.

D．How dust particles are spreading through the wind.

D．Numerous plastic water bottles were found each year.

3. What does Steve Allen say about plastics?

A．They should be recycled.	B．They do harm to weather.
C．They can be used to make all sorts of pesticides.	D．They carry harmful chemicals to human lungs.

4. What would be the best title for the passage?
