2 . Microplastic pollution has been detected in human blood for the first time, with scientists finding the tiny particles(微粒) in almost 80% of the people tested. The discovery shows the particles can travel around the body and may live in organs.

The impact on health is as yet unknown. But researchers are concerned as microplastics cause damage to human cells in the laboratory and air pollution particles are already known to enter the body and cause millions of early deaths a year.

Huge amounts of plastic waste are left in the environment and microplastics now pollute the entire planet, from the top of Mount Everest to the deepest oceans. People were already known to consume the tiny particles via food and water as well as breathing them in, and they have been found in the faeces (排泄物) of babies and adults.

The scientists analysed blood samples from 22 healthy adults and found plastic particles in 17. Half the samples contained PET plastic, which is commonly used in drinks bottles, while a third contained polystyrene, used for packaging food and other products. A quarter of the blood samples contained polyethylene, from which plastic carrier bags are made.

“Our study is the first indication that we have polymer particles(聚合物颗粒) in our blood — it’s a breakthrough result,” said Prof Dick Vethaak, an expert at Vrije Universiteit Amsterdam in the Netherlands. “But we have to extend the research and increase the sample sizes, the number of polymers assessed, etc.” Further studies by a number of groups are already under way, he said.

“It is certainly reasonable to be concerned,” Vethaak said. “The particles are there and are transported throughout the body.” He said previous work had shown that microplastics were 10 times higher in the faeces of babies compared with adults and that babies fed with

plastic bottles are taking millions of microplastic particles a day.

Vethaak acknowledged that the amount and type of plastic varied considerably between the blood samples. “But this is a pioneering study,” he said, with more work now needed. He said the differences might reflect short-term exposure before the blood samples were taken, such as drinking from a plastic-lined coffee cup, or wearing a plastic face mask.

“The big question is what is happening in our body?” Vethaak said. “Are the particles retained in the body? Are they transported to certain organs, such as getting past the blood-brain barrier? And are these levels sufficiently high to cause disease? We urgently need to fund further research so we can find out.”

1. What could be inferred from Paragraph 2?

A．Air Pollution particles can cause death eventually.

B．Microplastics can be deadly to humans.

C．There is no evidence that microplastics harm human cells.

D．Microplastics can travel throughout body and damage organs.

2. What can we learn about microplastics from Paragraph 4?

3 . Just like his parents and grandparents before him, Alaska teenager Carl Smith lives off the land, whether it’s catching salmon (鮭鱼) for dinner or collecting wood to keep warm in winter.

But the climate emergency is threatening the way Carl and his Yupik Eskimo family members have lived for generations, prompting (促使) the teenager to step into a role he never imagined he’d have: that of climate activist.

“I wanted to get the word out,” Carl, 18, tells People for the Earth Day special. “Nobody really knows what’s happening out here in rural Alaska.”

For Carl, home is Akiak, a small village of about 400 people who rely on the Kuskokwim River for salmon in the summer, and geese and moose (驼鹿) hunting in the spring and fall to keep their stomachs fed.

But as global temperatures rise, Alaska’s winters are getting shorter, and the permafrost (永冻土层) near Akiak is melting, causing large waves in the river that have been eroding (侵蚀) the shoreline as they crash; Carl estimates they’ve so far lost about 100 feet of land.

Carl’s concerns received national attention in 2019, when he and 15 other teenagers filed a landmark complaint with the United Nations Committee on the Rights of the Child, charging five countries with violating their rights as children by not doing enough to end the climate crisis and the threat it poses to their futures.

The complaint was spearheaded by attorney Michael Hausfeld, who says Carl stood out because climate change is directly affecting his life. “He’s experiencing it firsthand. He is watching his life slowly diminish (缩小) and disappear, M Hausfeld tells People. “Carl could become an icon for the concept of intergenerational equity (公正), which is an obligation of states to secure a living planet for the next generations.”

Carl traveled to New York for the Human Rights Day Summit, where he met fellow activists like Greta Thunberg and Alexandria Villasenor, who are also part of the complaint.

“When I heard the stories from people around the world, I felt like I was with them,” he says. “We’re experiencing different things, but in a way, it’s all the same. I just felt connected to them in some way.”

“I’m going to keep telling everyone that climate’s coming, climate’s changing, and it’s happening everywhere in the world,” he says. “If we don’t do anything about it, we won’t have a home to live in. I just hope everyone listens.”

1. What does the underlined phrase “get the word out” in paragraph 3 probably mean?

A．Let people know about something.

B．Conduct research on something.

C．Stop something from happening.

D．Go out for an adventure.

2. Which of the following is true according to this passage?

3. What’s the major problem that Akiak is facing?

A．The population is decreasing.

B．Some species are going extinct.

C．More and more land is being lost.

D．Forests are being destroyed.

4. What is Hausfeld’s attitude toward Carl’s actions?

A．Doubtful.

B．Critical.

C．Supportive.

D．Worried.

5. Why did Carl file the complaint?

4 . Human’s appetite for sand could increase 45 percent within four decades, according to researchers who say unchecked consumption risks environmental damage and shortages of a key material for urban expansion. Growing demand for building sand — which is used to make concrete, glass and other vital construction materials – has already seen the rise of sand pirates (盗贼) , with dozens of islands disappearing in Indonesia as a result of casual mining.

Xiaoyang Zhong at Leiden University and his colleagues have calculated that global building sand demand will jump from 3.2 billion tonnes a year in 2020 to 4.6 billion tonnes by 2060. The figure is based on a central situation of future population rises and economic growth, and modelled using estimates of concrete and glass consumption, and the floor area needed in buildings.But there is no reliable estimate for remaining sand reserves, so it is unclear if the world can bear such a big increase. “Sand, and the sand crisis (危机), has been overlooked, creating severe environmental and social consequences. If we don’t act now, we may not have enough sand to develop our cities,” says Zhong.

However, Zhong’s team found that about half the projected consumption in 2060 could be avoided if countries take a suit of measures, including extending the lifetime of buildings, reusing concrete, creating more lightweight building designs and using other materials, such as wooden frames. According to the model, the single biggest reduction in sand use could come from more efficient (有效的) use of space: distributing less floor space per person in buildings, sharing offices, and so on. “It’s hard to say how realistic these measures are. But we want this to happen,” says Zhong.

The research only looked at sand used for glass and concrete in buildings, so is an underestimate of total future demand. Granular data on sand consumption for the 26 world regions studied is also lacking, and not detailed enough for country-level breakdowns.

Failure to act will add existing environmental pressures on reserves of sand in lakes and rivers first, but absolute shortages shouldn't be overlooked, says Zhong. “It would be very questionable if this growing demand could be met,” he says.

1. What may cause the environmental and social effects according to Zhong?

A．Sand reserves are not enough.

B．The sand crisis is overestimated.

C．Sand crisis isn’t paid much attention to.

D．The construction industry is lack of sand.

2. How can we reduce the sand use most efficiently according to the study?

A．By reusing he building materials.

B．By lengthening the building’s lifetime.

C．By making use of space more wisely.

D．By preventing sand use completely.

3. What ‘s the shortcoming of the research?

A．It only studied the sand use in 26 areas.

B．It didn’t show the detailed data on sand use.

C．It didn’t take realistic measures on sand use.

D．It overlooked the total sand need in the future.

4. What does Zhong concern most about the sand crisis?

A．How we will take action to stop it.

B．Why its shortages are overlooked in most countries.

C．Whether the increasing sand need may be satisfied.

D．What damage the environmental pressures do to rivers.

5 . Placing large-scale renewable energy equipment is difficult and often met with criticism, especially in areas where landscape of the area is considered a cultural heritage(遗产) or is a tourist spot which brings in good income. Therefore, the human interaction is kept at a minimal rate to avoid damaging the environment.

Changes in biodiversity due to equipment of solar energy and wind power is thought to be more damaging than overall reduction in greenhouse gasses. This is one of the reasons why acquiring land for renewable energy equipment is so difficult, since traditional uses of land such as agriculture are preferred more than placing power plants. However, recent research shows that installing such renewable equipment actually promotes biodiversity.

Now a comprehensive research has been carried out on ‘The Effects of Solar Farms on Local Biodiversity‘ in UK by ecological consultants who proved these theories. The consultants studied 11 similar solar farms located around England and Wales along with their neighboring control farms to compare. Plants (crops), invertebrate(无脊椎动物), bird and bat surveys were carried out on both the farms. One test before solar arrays were set up on the land and then after.

The results of the study exceptionally proved that solar farms had significantly higher biodiversity than the control farms. The solar farm had by far the most positive effect on biodiversity when the farmland was replanted with a mixture of different seeds after the solar farm was constructed. This minimized use of agricultural chemicals and promoted marginal habitat space for other species.

The report further went on to say that reduction in greenhouse gas emissions was just one of the positive effects.

The other one was that the increase in wildlife and biodiversity inside the solar farms actually extended to areas surrounding the solar farm as well. Construction has always come with a downside of damage to the local ecosystems, but since building solar farms actually benefit the wildlife, there couldn’t be better news to hear! A good reason of improved biodiversity would be the fact that farm is shifted from monoculture farming to a variety of crops. The limited use of pesticides and herbicides contributes to safer practices. Moreover, the presence of solar equipment provides shade for birds to make their nests (be kind to animals).

1. What do most people think of renewable energy equipment?

A．It’s too expensive.

B．It may turn a tourist spot.

C．It will do damage to the land.

D．It can serve as a cultural heritage.

2. What difficulty may solar energy companies have according to the passage?

A．Developing power plants.

B．Obtaining enough farmland.

C．Collecting enough funding.

D．Producing enough equipment.

3. What ca we know about the study in UK by ecological consultants?

A．It is the first study in this field.

B．Its result is beyond expectation.

C．It suggested canceling solar farms.

D．It needed further study.

4. What can be the best title of the passage?

A．People are Going Wild for Solar.

B．Solar Power Is Starting to Take off.

C．Solar Energy Will Be in Urgent Need.

D．Solar Farms Help Increase Biodiversity.

6 . Fire ants are famous for their construction projects (as well as their burning bites). When they need to, colonies of these insects turn themselves into ladders, chains and walls. And when flood water rises, a colony can float to safety by making an unusual boat. The ants hold tightly to each other, forming a floating disk atop the water. The antraft may float for months seeking safe harbor. The ants on the bottom don’t drown, and the ants on the top stay dry. Working together, the ants float to safety — even though a single ant alone in the water will struggle to survive.

“They have to stay together as a colony to survive.” Nathan Mlot said.

Fire ants and water don’t mix. The ant’s hard outer shell, naturally repels water. A drop of water can sit on top of the ant like a backpack. When an ant does end up underwater, tiny hairs on its body can trap bubbles of air that give the bug a boost up.

To investigate the science behind the antraft, the scientists placed hundreds or thousands of ants at a time in the water. A group of ants took about 100 seconds, on average, to build a raft. The researchers repeated the experiment multiple times. Each time, the ants organized themselves the same way, creating a raft about the size and the thickness of a thin pancake. The rafts were flexible and strong, staying together even when the researchers pushed the rafts underwater.

The scientists then froze the rafts in liquid nitrogen and studied them under powerful microscopes to figure out how the ants kept everyone safe and the water out.

The team found that some ants used their jaws to bite other ants’ legs. Other ants joined their legs together. Thanks to these tight bonds, say the scientists, the ants did a better job at keeping the water away than any one ant could do on its own. By working together, thousands of ants can stay alive in the face of a crisis like a flood by using their own bodies to build a boat.

8 . When birds’ habitat is destroyed, some species don’t make it while others survive. But what happens at the very beginning of the process, just as a bird’s habitat starts to change? Research in Argentina’s Monte Desert has provided some answers. There are lots of trees, bushes, grasses and flowering plants in the protected parts of the desert. With so many options, most seed-eating birds choose to focus on large grass seeds. The birds can get all the energy and nutrients they need with minimal effort.

But when cattle show up to graze the desert’s natural landscape, birds face changes in food supply. Some birds are happy to change their diets in response. But others, not so much. And it’s the ones set in their ways that are at the highest risk. Understanding how birds react to grazing can help researchers solve the problem of those species.

Ecologists from the Argentine Arid Zones Research Institute compared soil samples from the desert’s Nacunan biosphere reserve to samples from two neighboring cattle farms. It was discovered that grass seeds — the birds’ favorites — were just one-quarter as likely to be found on the farms compared with the reserve. Next, they caught birds to see what they were eating. The Common Diuca-Finch and the Rufous-Collared Sparrow had adjusted their diets, choosing to eat their less preferred options on the farms, even while they still focused on large grass seeds in the reserve.

Meanwhile, the Many-Colored Chaco Finch and the Ringed Warbling-Finch were apparently unable to change their diets. Even on the farms, they worked hard to find the few grass seeds available. If they burn more energy searching for food than they get from the few grass seeds they find, they could starve. At best, their inflexible dietary could limit their ability to reproduce or to care for their young.

Studies like this can help predict which species are at higher risk and help farmers protect these poor species, even while allowing their livestock to graze. For example, the farmers can plant new species for their cattle that will also be more delicious and nutritious for local seed-eating birds. The cows won’t care about the menu change — but the birds sure will.

1. Why can some seed-eating birds easily get their food in the protected parts of the desert?

A．Because of plant diversity.	B．Because there are fewer birds.
C．Because there are many small grass seeds.	D．Because of their long-distance flying ability.

2. Researchers study how birds react to grazing so as to ________.

A．make birds and cattle live in peace	B．help birds change their diets
C．make cattle leave the desert	D．help birds most in danger

3. What did ecologists from the research institute find?

A．Birds only ate large grass seeds on the farms.

B．Some birds changed their diets in the reserve.

C．There were more birds’ favorite seeds on the farms than in the reserve.

D．Some birds chose their favorites in the reserve but other food on the farms.

4. It can be inferred that grazing cattle can __________.

A．drive most birds off the farms	B．change the menu of some birds
C．make birds like other seeds best	D．have little effect on birds’ food chains

5. Which proverb can best describe the method of farmers’ planting new species?

A．Every coin has two sides.	B．Kill two birds with one stone.
C．Birds of a feather flock together.	D．There is no garden without weeds.

9 . Most of Florida is a flat peninsula (半岛) with water on three sides and houses built as close to the shoreline as possible. For one thing we are more frequently the target of hurricanes than any other state; for another, our geography makes us more easily to be hurt by rising seas.

A news story about climate change in Florida popped up. Historically, scientists believed mangroves (红树林) didn’t live farther north than Cedar Key, in the middle of Florida’s Big Bend. But that’s not the case anymore. Samantha Chapman, a biology professor who’s been studying how Florida’s mangroves have been migrating (迁移), found them up near the St Mary’s River, which forms the border between Florida and Georgia. It seems that they soon be marching through Georgia and becoming a thriving new component of coastal habitats.

But a coastal biologist named Blair Witherington took issue on the matter. The mangroves weren’t spreading into a new territory, he pointed out. They were entering areas that had been classified as saltmarsh (盐沼), where the landscape was dominated by cordgrass. Saltmarsh and mangrove create very different habitats that attract a very different set of animals. “When one community replaces the other, this diversity is lost,” Witherington remarked. Changing the animals’ habitat has the potential to influence the whole food chain, making a widespread difference.

What was driving this? “Mangroves can survive a short freeze, but not a prolonged, hard freeze. By combing through the weather records kept by the state’s orange juice industry, biologists have been able to document that Florida is having fewer prolonged hard freezes than it used to. Then the mangroves have adapted by expanding their range.” Samantha explained.

“They’ve adapted in another way, too. Not only are the mangroves spreading into areas that once were unfriendly to them, but they have also changed their life cycle to speed things up. Normally it takes them about 15 years of growth before they start making seeds. Now, as they get into these marshes, they’re producing seeds when they’ re only a couple of years old,” Samantha said.

The problem with having too many mangroves by the sea is that climate change may overwhelm them. A study by the US Geological Survey said sea level rise could wipe out mangroves all along the Florida coast. So, here’s the question we humans have to consider: Nature is finding ways to adapt to how we’ve changed the climate. What are we doing to adapt to it? Or at least slow it down?

1. What can we learn about the state of Florida?

A．It could be affected by high tides easily.

B．Its geography fuels shipbuilding industry.

C．Its houses are built in a high-lying but flat area.

D．It is often hit by tornadoes and suffers huge losses.

2. What is the news story about Florida’s mangroves?

A．They migrate to warmer regions.

B．They are marching into a new habitat.

C．They form the border between Florida and Georgia.

D．They are introduced into Florida to prevent flooding.

3. Which of the following would Blair Witherington agree with?

A．Saltmarsh is fragile and requires urgent protection.

B．Florida includes a rich diversity of natural habitats.

C．The benefits of the mangroves outweigh their troubles.

D．Everything in the ecosystem is connected complicatedly.

4. What are the 4th and 5th paragraphs mainly about?

A．What mangroves had to face in their habitats.

B．Whether mangroves had influence on other plants.

C．How mangroves adapted to the changing environment.

D．Why mangroves had a different life cycle in marshes.

5. What can we infer from the last paragraph?

A．Human beings are supposed to worship nature.

B．It is urgent to grow more mangroves along coastlines.

C．Measures against mangroves’ migration are far from enough.

D．What we should do to stop the climate change is still up in the air.
