文章大意:本文是一篇说明文。文章主要介绍了艺术家Benjamin Von Wong使用海洋中的塑料垃圾制作了一个巨型雕塑,极其震撼,引发人们对塑料污染的反思。

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.

1. What are Von Wong’s artworks intended for?
A.Beautifying the city he lives in.B.Introducing eco-friendly products.
C.Drawing public attention to plastic waste.D.Reducing garbage on the beach.
2. Why does the author discuss plastic straws in paragraph 3?
A.To show the difficulty of their recycling.
B.To explain why they are useful.
C.To voice his views on modern art.
D.To find a substitute for them.
3. What effect would “Truckload of Plastic” have on viewers?
A.Calming.B.Disturbing.
C.Refreshing.D.Challenging.
4. Which of the following can be the best title for the text?
A.Artists’ Opinions on Plastic Safety
B.Media Interest in Contemporary Art
C.Responsibility Demanded of Big Companies
D.Ocean Plastics Transformed into Sculptures

2 . California has lost half its big trees since the 1930s, according to a study to be published Tuesday and climate change seems to be a major factor(因素).

The number of trees larger than two feet across has declined by 50 percent on more than 46, 000 square miles of California forests, the new study finds. No area was spared or unaffected, from the foggy northern coast to the Sierra Nevada Mountains to the San Gabriels above Los Angeles. In the Sierra high country, the number of big trees has fallen by more than 55 percent; in parts of southern California the decline was nearly 75 percent.

Many factors contributed to the decline, said Patrick McIntyre, an ecologist who was the lead author of the study. Woodcutters targeted big trees. Housing development pushed into the woods. Aggressive wildfire control has left California forests crowded with small trees that compete with big trees for resources(资源).

But in comparing a study of California forests done in the 1920s and 1930s with another one between 2001 and 2010, McIntyre and his colleagues documented a widespread death of big trees that was evident even in wildlands protected from woodcutting or development.

The loss of big trees was greatest in areas where trees had suffered the greatest water shortage. The researchers figured out water stress with a computer model that calculated how much water trees were getting in comparison with how much they needed, taking into account such things as rainfall, air temperature, dampness of soil, and the timing of snowmelt(融雪).

Since the 1930s, McIntyre said, the biggest factors driving up water stress in the state have been rising temperatures, which cause trees to lose more water to the air, and earlier snowmelt, which reduces the water supply available to trees during the dry season.

1. What is the second paragraph mainly about?
A.The seriousness of big-tree loss in California.
B.The increasing variety of California big trees.
C.The distribution of big trees in California forests.
D.The influence of farming on big trees in California.
2. Which of the following is well-intentioned but may be bad for big trees?
A.Ecological studies of forests.
B.Banning woodcutting.
C.Limiting housing development.
D.Fire control measures.
3. What is a major cause of the water shortage according to McIntyre?
A.Inadequate snowmelt.B.A longer dry season.
C.A warmer climate.D.Dampness of the air.
4. What can be a suitable title for the text?
A.California’s Forests: Where Have All the Big Trees Gone?
B.Cutting of Big Trees to Be Prohibited in California Soon
C.Why Are the Big Trees Important to California Forests?
D.Patrick McIntyre: Grow More Big Trees in California

Your Cat Might Not Be Ignoring You When You Speak

Every cat owner has a story to tell of being blanked by their cat. We call to our cat, it turns away, and some of us might be left     1     (wonder) why we didn’t get a dog. But your cat may be listening after all. More than that, it     2     (care) more than you may think.

A study by French researchers     3     (publish) last month in the journal Animal Cognition found that not only do cats react to what scientists call cat-directed speech — a high-pitched (高音的) voice similar to     4     we talk to babies — they react to who is doing the talking.

“We found that hearing their owners using a high-pitched voice, cats reacted more than when hearing their owner speaking normally to another human adult,” said Charlotte de Mouzon, an author of the study. “But it actually didn’t work when it came from a stranger’s voice.”

    5     studies involving dogs, analyzing cat behavior is difficult, which is part of why humans understand them less. Cats are often so stressed by being in a lab     6     meaningful behavioral observations become impossible. And forget about trying to get a cat     7     (sit) still for an M.R.I. scan (核磁共振扫描) to study its brain function.

So the researchers for the latest study went to the cats’ homes and played recordings of different types of speech and different speakers. At first, there was concern from Dr. de Mouzon and her team for lack of reaction from the cats, but upon analysis of the film recordings, delicate reactions     8     (notice). “It could be just moving an ear or turning the head to the speaker or even freezing what     9     were doing,” Dr. de Mouzon said.

In the study, there were a few cases     10     cats would approach the speaker playing a voice and meow. “In the end, we had really clear gains in the cat’s attention when the owner was using cat-directed speech,” Dr. de Mouzon said.

文章大意:这是一篇说明文。文章介绍了因为人类照明导致的光污染相关情况。

4 . Human beings have somehow managed to engineer the night to receive us by filling it with light. This kind of control is no different from the feat ( 壮 举 ) of damming a river. Its benefits come with_________ — called light pollution — whose effects scientists are only now beginning to study. Light pollution is largely the result of bad lighting design. _________ lighting washes out the darkness of night, altering light levels and light rhythms to which many forms of life, including ourselves, have_________. Wherever man-made light spills into the natural world, some aspects of life-migration, reproduction, feeding-is affected.

For most human history, the phrase “light pollution” would have_________. Imagine walking towards London on a moonlit night around 1800, when it was Earth’s most populous city. Nearly a million people lived there, _________ candles, torches and lanterns, as they always had. Only a few houses were lit by gas, and there would be no public gaslights in the streets or squares for another seven years. From a few miles away, you would have been more likely to_________ London than to see its dim collective glow.

We’ve lit up the night as if it were a(n) _________ country. As a matter of fact, among mammals (哺乳动物) alone, the number of species active at night is astonishing. Light is a powerful biological force, and on many species it acts as a magnet attracting them to it. The effect is so powerful that scientists speak of songbirds and seabirds being_________ by searchlights on land or by the light from gas flares on marine oil platforms, circling and circling in the thousands until they drop.

It was once thought that light pollution only affected astronomers, who need to see the night sky in all its glorious clarity. Unlike astronomers, most of us may not need a_________ view of the night sky for our work. __________, like most other creatures, we do need darkness. __________ darkness is pointless. It is as essential to maintaining our biological welfare as__________ itself; the price of modifying our internal clockwork means it doesn’t operate as it should, causing various physical discomforts. So fundamental are the regular rhythms of waking and sleep to our being that__________ them is similar to altering our center of gravity.

In a very real sense, light pollution causes us to__________ our true place in the universe, to forget the scale of our being, which is best__________ against the dimensions of a deep night with the Milky Way — the edge of our galaxy — arching overhead.

文章大意:本文是一篇说明文,介绍了时尚行业已经成为地球上最具有破坏性的行业之一,是仅次于石油行业的最不环保的行业,现在正面临惩罚。

5 . What do you know about fashion? The fashion industry, which has become one of the most _________ to the planet, is having a moment of punishment. But which changes make a difference, and which ones just _________ in the wash? In fact, the fashion industry is second only to the oil industry, the most environmentally unfriendly industry.

A friend of mine _________ an antique clothes store in the north of London. Business has been good for many years, which makes her acquire a large fortune. Every few weeks, she visits a vast storehouse on the edge of the city to go through piles of clothing. Most of it is _________, but if you know what you are looking for, there are raw diamonds. The storehouse has a long history. It was once a clearing house for the low-quality wool scraps(碎料) that were used to make cheap clothing for the _________ in Victorian Britain. A century on, _________ has changed. Nowadays, it is full of modern-day inferior products, all _________ cheap clothing made for the masses around the world. Except that this stuff is going to be burned or buried, not being reused.

The items are the products of an industry that, in the past 30 years, has become one of the most successful and also most _________ on the planet. Known as fast fashion, it has filled our wardrobes(衣柜) with cheap and cheerful clothes. But after three decades of continuous growth, the model is in _________ with fundamental environmental limits and there is widespread agreement – even from within the industry – that it is time to ____________. Otherwise, “Fast fashion” creates a mountain of unsellable, cheap clothing that ends up in a terrible place.

“The fashion industry represents a key environmental ____________,” says Kirsi Niinimäki at Aalto University in Espoo, Finland. “Eventually, the long-term stability of the fashion industry ____________ the total abandonment of the fast-fashion model.” Like fast food, fast fashion is all about instant ____________ on the cheap.

One wonders: What can we do about it? Don’t you have any clothes on? It’s not that ____________. More importantly, don’t waste, learn to control your desires and ____________ falling into this “Fast fashion” lifestyle. As the guardian columnist Lucy Seagal once said, the “Fast fashion” industry is profit-driven, but consumers who have experienced “over-consumption” will naturally grow tired of it, and the market will have its choice.

6 . By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.

At the heart of the phenomenon lie tiny marine microorganisms(海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.

Phytoplankton live at the ocean surface, where they pull carbon dioxide(二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.

Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. “Not only are the quantities of phytoplankton in the ocean changing. ” she said, “but the type of phytoplankton is changing.”

And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.

Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”

1. What are the first two paragraphs mainly about?
A.The various patterns at the ocean surface.
B.The cause of the changes in ocean colour.
C.The way light reflects off marine organisms.
D.The efforts to fuel the growth of phytoplankton.
2. What does the underlined word “vulnerable” in Paragraph 3 probably mean?
A.Sensitive.B.Beneficial.C.Significant.D.Unnoticeable.
3. What can we learn from the passage?
A.Phytoplankton play a declining role in the marine ecosystem.
B.Dutkiewicz’s model aims to project phytoplankton changes.
C.Phytoplankton have been used to control global climate.
D.Oceans with more phytoplankton may appear greener.
4. What is the main purpose of the passage?
A.To assess the consequences of ocean colour changes.
B.To analyse the composition of the ocean food chain.
C.To explain the effects of climate change on oceans.
D.To introduce a new method to study phytoplankton.

7 . I’ve been in an 18-year love-hate relationship with a black walnut tree.

It’s a unique tree. In late September or early October, falling fruits as hard as baseballs threaten the skulls (头骨) of you, your children, your neighbors and those that reside next door to them. Umbrellas in the yard are a must while dining in early August, and as for me, I wear my bike helmet while working in the garden.

The black walnut also releases a chemical substance through its roots as a competitive strategy. It’s poisonous to several common plants. There have been many new plant varieties that I brought home with hopes that maybe the black walnut would accept them, but they failed to flourish.

What does work are native plants that naturally grow in the area. Native plants are important to have around since they provide beneficial pollinators (传粉者) like birds, bees and butterflies with seeds and contribute to a healthy and biodiverse environment. Native plants for this area are generally easy to grow, so they experience less stress.

Have I thought of getting rid of this giant pain in my tiny backyard? Yes, however, getting rid of this tree standing at 50 feet with an 87-inch trunk is next to impossible. It’s also protected under the law. Rightfully so. Trees are important to the urban forest and for all of those that inhabit it.

Sometimes I think about my life without the black walnut. I can’t imagine a spring without the birds who arrive every year and loudly sing their songs before dawn. I’d miss falling asleep on lazy weekend afternoons as I look up into its leaves.

Every spring, I wonder what the season holds: What are the chances of being knocked unconscious while barbecuing? Like any good relationship, I’ll never be pleased. I’m stuck with this tree, so I’ll listen to its needs and give it the space it requires. In return, my walnut offers a habitat for wildlife and a reminder.

1. Why does the author wear a bike helmet while working in the garden?
A.To protect the injured skull.B.To prevent herself from sunburn.
C.To avoid being hit by the nuts.D.To reduce the chance of getting bitten by bees.
2. What is the tree’s survival strategy?
A.It attracts beneficial pollinators.
B.It lets out poison to drive away pests.
C.It produces a chemical fatal to some plants.
D.It competes for nutrition with similar species.
3. Which of the following DOESN’T account for the author’s love-hate relationship with the tree?
A.The volume of its fruits may bring inconvenience.
B.The tree outcompetes the native plants in the garden.
C.The tree is home to numerous birds and other creatures.
D.The presence of the tree takes up much space of the garden.
4. The author most probably got a reminder from the tree that ________.
A.it’s better to give than to take
B.trees and plants have their own ways to flourish
C.even a good relationship is not always trouble-free
D.acceptance, instead of resistance, is the better way to be

Japan Releases Nuclear Wastewater into the Pacific. How Worried Should We Be?

Japan has started releasing wastewater into the ocean. But this isn’t the kind of wastewater     1     flows from city streets into stormwater drains. It’s treated nuclear wastewater used to cool damaged reactors at the Fukushima Daiichi nuclear power plant,     2     (strike) by an earthquake over a decade ago.

Since the accident, over 1.3 million tons of nuclear wastewater     3     (collect), treated, and stored in a tank farm at the plant. That storage space is about to run out, the Japanese government says, leaving no choice other than     4     (begin) dumping the wastewater into the Pacific.

Japan’s discharge plan involves incrementally (递增地) releasing it over the next three decades, although some experts say it could take longer, given the amount still     5     (produce). Some of Japan’s neighbors are criticizing the plan as unilateral and dangerous. On May 15, South Korea’s opposition leader ridiculed Japanese leaders’ claims that the water is safe enough to drink: “    6     it is safe enough to drink, they should use it as drinking water.”

Now, American scientists are raising concerns that marine life and ocean currents could carry harmful radioactive isotopes (同位素) —also called radionuclides—    7     the entire Pacific Ocean.

“It’s a trans-boundary and trans-generational event,” says Robert Richmond, director of the Kewalo Marine Laboratory at the University of Hawaii. “    8     released into the ocean off of Fukushima is not going to stay in one place.”

The radionuclides could be carried by ocean currents, especially the cross-Pacific Kuroshio current. Marine animals that migrate great distances could spread them too. No     9    (worrying) as carriers, Richmond says, are phytoplankton—free-floating organisms that are the basis of the food chain for all marine life and can capture radionuclides from the Fukushima cooling water. When swallowed, those isotopes may “accumulate in a variety of fish, marine mammals, and humans.”

Richmond and Buesseler say that     10     they’ve been allowed access to much of the same data as the IAEA, they remain suspicious. “The root of this problem is that they are moving already with a plan that has not yet shown that it will work,” Buesseler says. “They’re saying, ‘We can make it work. We’ll treat it as many times as it takes.’ If you want to put a nickname on this plan, it’s ‘trust us; we’ll take care of it.’”

文章大意:本文是一篇说明文。文章介绍了因为全球变暖,导致细菌的感染范围扩大,从而导致致死率特别高的感染。

9 . Climate experts have warned about the many ways a warming planet can negatively affect human health. ________ global temperatures are predicted to increase by 1.5℃ by the 2030s, that risk is becoming increasingly real.

One long-held prediction that appears to be coming true — according to the results of a study recently published in Nature Scientific Reports — is how climate change might enhance ________ of bacteria that thrive and spread through warm sea waters and cause an infection with a particularly high ________ rate.

Vibrio vulnificus (创伤弧菌) flourishes in salty or brackish waters above 68℉. Infections are currently rare in the U.S., but that’s likely to change. Using 30 years of data on infections, scientists at the University of East Anglia in the U.K. found that Vibrio vulnificusis ________ from its historic Gulf Coast range, with more Northern states reporting infections as waters become warmer.

“We’re seeing the core ________ of infections extending to areas that traditionally have very few and very rare cases,” says Elizabeth Archer, a Ph.D. researcher and ________ author of the study. “But these areas are now coming into the main area of infections.”

Based on the latest data on how much the world’s water and air temperatures will rise, the scientists predict that by 2081, Vibrio vulnificus infections could reach every state along the U.S. East Coast. Currently, only about 80 cases are reported in the U.S. each year; by 2081, that could go up to over three-fold, the authors say.

Such a proliferation could have serious health consequences. Vibrio vulnificus kills approximately 20% of the healthy people it infects, and 50% of those with weakened immune systems. There is little evidence that antibiotics can ________ the infection, but doctors may prescribe them in some cases. People can get infected either by eating raw shellfish like oysters or by exposing small ________ to waters where the bacteria live, which can lead to serious skin infections.

Warming sea temperatures aren’t the only reasons behind the rise of Vibrio vulnificus. Hotter air also draws more people to the coasts and bays, bringing them into closer contact with the bacteria.

“The bacteria are part of the natural marine environment, so I don’t think we can ________ it from the environment,” says Archer. “It’s more about mitigating infections by increasing ________ of the risk.”

To alert people to the growing threat, ________ systems are needed to track when concentrations of bacteria start to rise, similar to currently available pollen and pollution alarm.

Vbrio vulnificus is so ________ to temperature changes that concentrations could bloom after even a day of warmer water, so consistent monitoring and alerts are critical, says Iain Lake, professor of environmental epidemiology at University of East Anglia and senior author of the paper.

Lake says the expansion of Vibrio vulnificus is concerning for public health since the bacteria are now invading waters closer to heavily ________ areas, such as New York and Philadelphia. “Everyone can get a Vibrio vulnificus infection,” he says. “But the more ________ there is between warmer waters and people, the more the bacteria can move into populations ________ the elderly and those with other health conditions, who are more vulnerable to infections.”

10 . The Amazon is warming three times faster than the global average

It is perhaps the most ironic symbol of the life on our planet. The Amazon is the world’s largest and most bio-diverse tropical rainforest and a huge trap for carbon dioxide. The harms of _________ in this vital resource are old news. But now, the time on the clock is running out. It seems that the world’s biggest rainforest is about to turn into the world’s biggest environmental _________. “We are about to collapse,” says Luciana Gati at Brazil’s National Institute for Space Research. “We are in a(n) _________, we need action now.”

Gati has spent years _________ the Amazon from the air. She believes we are as little as five years from a point of no return, where rainforest begins to turn into dry land. It is also the point at which billions of tons of carbon would be _________ into the atmosphere. “It’s a nightmare,” she says.

That nightmare situation is the well-known Amazon _________ point, where the ecosystem can no longer cope with the damage of the forest cutting. Like a domino game, one brick falling will _________ the whole tower to collapse in a heap.

Warnings that this is approaching have now taken on extreme urgency. The rate of deforestation has increased sharply and is fast approaching the theoretical _________. In September, a group of more than 200 experts, including Gatti, released an assessment of the situation. The conclusion: we are on the _________ of disaster.

Scientists first began to seriously worry about a potential Amazon tipping point in about 2000, when some studies warned that a combination of climate change and deforestation could cause the rainforest to __________.

A few years later, a team of Brazilian scientists put numbers on it. They __________ that in central, southern and eastern parts of the Amazon, a loss of 40% of the forest cover from pre-industrial levels, or 3°C warming would reduce rainfall so much that the rest of the forest would die of __________ and turn into a dry land in less than a decade.
