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

文章大意:本文是一篇说明文。主要介绍了材料工程师Nzambi Matee通过自己的努力,创造性地解决塑料垃圾污染的问题。

2 . Kenya has been at the forefront (前沿) of the global war on plastic since the government banned single-use plastics in protected areas in June 2020. Unfortunately, the preventive measures have barely received attention. Hundreds of tons of industrial and consumer polymer waste continue to get dumped into landfills daily. However, if 29-year-old Nzambi Matee has her way, the unsightly plastic heaps will soon be transformed into colorful bricks.

The materials engineer’s seeking to find a practical solution to control plastic pollution began in 2017. She quit her job and set up a small lab in her mother’s backyard. It took her nine months to produce the first brick and even longer to convince a partner to help build the machinery to make them. But the determined eco-entrepreneur was confident in her idea and did not give up.

She says, “I wanted to use my education to handle plastic waste pollution. But I was very clear that the solution had to be practical, sustainable, and affordable. The best way to do this was by channeling the waste into the construction space and finding the most efficient and affordable material to build homes.” Her company produces over 1,500 bricks a day. The pavers are made using a mix of plastic products that cannot be reprocessed or recycled.

The collected plastic is mixed with sand, heated at very high temperatures, and compressed (压缩) into bricks that vary in color and thickness. The resulting product is stronger, lighter, and about 30 percent cheaper than concrete bricks. More importantly, it helps repurpose the lowest quality of plastic. “There is that waste they cannot process anymore; they cannot recycle. That is what we get.” Matee says.

Matee is not nearly done. Her dream is to reduce the mountain of trash to just a hill by increasing production and expanding her offerings. She says, “The more we recycle the plastic, the more we produce affordable housing, the more we created more employment for the youth.”

1. What does the underlined sentence in paragraph 1 imply?
A.Matee’s method can be effective if adopted.B.Matee’s idea has been widely accepted.
C.Colorful bricks are in huge demand.D.Plastic waste hasn’t attracted enough attention.
2. Which of the following can best describe Nzambi Matee?
A.Generous and ambitious.B.Confident and grateful.
C.Creative and resolved.D.Optimistic and modest.
3. What is Nzambi Matee’s ultimate purpose in using a mix of plastic products?
A.to build cheaper houses.B.to support the government.
C.to create job opportunities.D.to tackle plastic pollution.
4. Which of the following is the best title for the text?
A.Kenya: Pioneer in Banning Plastic Single-use Plastics
B.Nzambi Matee: Innovator in Solving Plastic Waste
C.Mix of Plastic Products: A New Construction Material
D.Plastic Recycling: A Creative Solution to Pollution

3 . Baggy has become the first dog in the UK—and potentially the world—to join the fight against air pollution by recording pollutant levels near the ground.

Baggy wears a pollution monitor on her collar so she can take data measurements close to the ground. Her monitor has shown that air pollution levels are higher closer to ground level, which has helped highlight concerns that babies and young kids may be at higher risk of developing lung problems.

Conventional air pollution monitors are normally fixed on lampposts at about nine feet in the air. However, since Baggy stands at about the same height as a child in a pushchair(婴儿车), she frequently records pollution levels which are much higher than the data gathered by the Environment A gency.

The doggy data research was the idea of Baggy's 13-year-old owner Tom Hunt and his dad Matt. The English youngster noticed that pollution levels are around two-thirds higher close to the ground than they are in the air at the height where they are recorded by the agency. Tom has since reported the shocking findings to the government in an attempt to emphasise that babies are at higher risk of developing asthma(哮喘).

Matt Hunt said he was "very proud" of his son because “when the boy gets an idea, he keeps his head down and gets on with it, and he really does want to do some good and stop young kids from getting asthma."

“Tom built up a passion for environmental protection at a very early age," Matt added. “He became very interested in gadgets(小装置). About one year ago, he got this new piece of tech which is like a test tube. One Sunday afternoon, we went out to do some monitoring, and he said, why don't we put it on Baggy's collar and let her monitor the pollution?'So we did it."

Tom said, "Most of the time, Baggy is just like any other dog. But for the rest of the time she is a super dog, and we are all really proud of her."

1. With a monitor on her collar, Baggy can ____________.
A.take pollutant readingsB.record pollutant levels
C.process collected dataD.reduce air pollution
2. What can we learn from the Baggy data?
A.High places are free of air pollution.
B.Higher pushchairs are more risky for kids.
C.Conventional monitors are more reliable.
D.Air is more polluted closer to the ground.
3. What is Tom's purpose of doing the research?
A.To warn of a health risk.B.To find out pollution sources.
C.To test his new monitor.D.To prove Baggy's abilities.
4. According to the passage, which word can best describe Tom Hunt?
A.Modest.B.Generous.C.Creative.D.Outgoing.

文章大意:这是一篇说明文。文章主要介绍了在人们当今的生活中污染是最严重的问题,以及为了减少污染,我们该如何做。

4 . Hundreds of years ago, life was harder than it is today. People didn't have modern machines.

Life today has brought new problems. One of the biggest problems is pollution. Water pollution has made our rivers and lakes dirty. It kills our fish and pollutes our drinking water. Noise pollution makes us talk louder and become angry more easily. Air pollution is the most serious kind of pollution to all living things in the world.

Cars, planes and factories all pollute our air every day. Sometimes the polluted air is so thick that it is like a quilt over a city. This kind of quilt is called smog.

Many countries are making rules to fight against pollution. Factories must now clean their water before it is thrown away, and they mustn't let dirty smoke go into the air.

We need to do many other things. We can put waste things in the dustbin and do not throw them on the ground. We can go to work by bus or with our friends in the same car. If there are fewer people driving, there will be less pollution.

Rules are not enough. Every person must help to fight against pollution.

1. Hundreds of years ago, life was much harder than it is today because_________
A.there were many problemsB.there were too many people
C.there were wars now and thenD.there were no modern machines.
2. The most serious kind of pollution is________
A.noise pollutionB.water pollutionC.air pollutionD.waste things
3. What does the underlined word “it” in Paragraph 3 refer to?
A.The air.B.The city.C.The quilt.D.The smog.
4. To fight against the pollution, we must_________
A.clean water after it is thrown awayB.throw waste things in the dustbin
C.let dirty smoke go into the airD.encourage more people to drive to work

文章大意:本文是一篇说明文。文章主要介绍光污染正在夺走我们的夜空,使得星星在我们眼前消失。

5 . In the endless sky, the unaided human eye should be able to perceive several thousand stars on a clear, dark night. Unfortunately, growing light pollution has impeded people from the nightly view.

New citizen-science-based research throws alarming light on the problem of “sky glow”-the diffuse illumination (漫射照明) of the night sky that is a form of light pollution. The data came from crowd-sourced observations collected from around the world as part of Globe at Night, a program developed by astronomer Connie Walker.

Light pollution has harmful effects on the practice of astronomy but also on human health and wildlife, since it disturbs the cycle from sunlight to starlight that biological systems have evolved alongside. Furthermore, the loss of visible stars is a great loss of human cultural heritage. Until relatively recently, humans throughout history had an impressive view of the starry night sky, and the effect of this nighty spectacle (壮观) is evident in ancient cultures.

Globe at Night has been gathering data on star visibility since 2006. Anyone can submit observations through the Globe at Night web application. Participants record which one best matches what they can see in the sky without any telescopes or other instruments.

Researchers find that the loss of visible stars indicates an increase in sky brightness of 9.6% per year while roughly 2% is measured by satellites. Existing satellites are not well suited to measuring sky glow as it appears to humans, because they can not detect wavelengths shorter than 500 nanometers (纳米). White LEDs, with shorter wavelengths under 500 nanometers, now are increasingly commonly used in outdoor lighting. But human eyes are more sensitive to these shorter wavelengths at nighttime. Space-based instruments do not measure light from windows, either. But these sources are significant contributors to sky glow us seen from the ground.

“The increase in sky glow over the past decade underlines the importance of redoubling our efforts and developing new strategies to protect dark skies,” said Walker. “The Globe at Night dataset is necessary in our ongoing evaluation of changes in sky glow, and we encourage whoever can to get involved to help protect the starry night sky.”

1. What does the underlined word “impeded” in the first paragraph mean?
A.separated.B.disabled.C.demanded.D.protected.
2. What does the loss of visible stars lead to?
A.Poorer human health.B.Fewer wildlife species.
C.More delicate biological systems.D.Less nightly culture elements of the sky.
3. What does the author stress in paragraph 5?
A.Crowd sourced data are invaluableB.Shorter wavelengths are hard to detect.
C.Satellites play a vital role.D.White LEDs are widely used.
4. What can be inferred from Walker’s words?
A.Their consistent efforts pay off.B.The dataset needs to be updated.
C.The sky glow has been over-emphasized.D.More participants are expected to join in.

6 . 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.

1. What’s the truth of “wish-cycling” according to the first paragraph?
A.The desire to lead a sustainable life.
B.The good intention to help recycling.
C.The habit of throwing items that end up in landfills.
D.The practice of recycling items that can not be recycled.
2. What has experts at Biffa concluded after their analysis?
A.People are becoming more eco-conscious.
B.Wish-cycling is on the rise in recent years.
C.Pollution happens less frequently in recycling facilities.
D.People are used to cleaning recyclable waste before putting it in the bin.
3. Which of the following is a proper way of recycling?
A.Dispose of electronics together with household waste.
B.Skip the step of checking the on-packaging recycling label.
C.Check the resin code of plastics to see whether it is recyclable or not.
D.Cutoff the top of old pizza box and throw the rest to the recycling bin.
4. Which is the most suitable title for the text?
A.Recycling: a Big ProjectB.Wish-cycling: a New Trend
C.Wish-cycling: a Growing ConcernD.Pre-cycling: an Effective Method

文章大意:这是一篇议论文。文章主要论述了英国空气污染严重的问题,这会引起相关疾病,但英国政府却毫不作为,甚至试图寻求排放更大污染的办法,因此认为英国政治家应当受到抨击。

7 . Last week came solid evidence that living in toxic Britain can seriously harm your health. Cardiologists at Queen Mary University of London found that even "safe" levels of air pollution are linked to heart abnormalities similar to those seen during the early stages of heart failure. Their study of almost 4,000 people was backed up by a major US study which showed that higher exposure to fine particles and nitrogen oxides is linked to an acceleration in the hardening of the arteries (动脉).

We have long known that air pollution leads to coughing, shortness of breath and irritation in the eyes, nose and throat. It is also clearly linked to respiratory diseases such as asthma and bronchitis, as well as diabetes and some cancers. It is now beyond doubt that children's health is greatly affected, and links have been made between it and Parkinson's, Alzheimer's, dementia and congenital birth defects.

The statistics are alarming. In the UK, more than 2 million people suffer from cardiovascular (心血管的) diseases, and nearly one in seven men and one in 12 women will go on to die from them. Heart disease costs the UK economy nearly £30 bn a year to treat, as much as the state spends on secondary education. It is one of the greatest single drains on the public purse. Britain, however, rejects common sense, and shows little sign that it wants to seriously address pollution any time soon.

Despite the mounting evidence of air pollution's costs and health impact, Britain has had to be dragged screaming through the courts to make it comply with minimal clean air guidelines and laws. Successive governments have continually tried to evade their legal responsibilities, spending millions of pounds fighting in the courts and lobbying the EU to be allowed to continue to pollute.

The government now has a new draft clean air strategy our for consultation until 14 August and claims to be acting faster to tackle air pollution than almost every other major developed economy. It pledges to halve the number of people living in places that do not meet World Health Organization pollution guidelines, and it propose to end the sale of new diesel and petrol cars and vans by 2040.

But intending to cut the air pollution bill by around 12.5% in 12 years and waiting 20 years to be rid of the worst vehicles seems criminally weak. Meanwhile, government is knowingly forging ahead with infrastructure plans that will inevitably increase air pollution. The effect will inevitably be to massively increase air pollution and health costs for millions of Britons.

So could the car-clogged streets of Sunder-land, Birmingham and London, where I lived for many years, have contributed to my disease and those of millions of others? Probably. Could the oil companies be responsible for far more than climate change? Certainly. Could Britain's monstrous and mounting bill for heart disease be partly due to the highly polluting diesel cars that governments so scandalously encouraged us to drive? Quite possibly.

What is certain is that air pollution is now an international scandal, and the cause of a health emergency that governments and industry have failed to address. It undoubtedly threatens life more than any war or disaster. When there are clear alternatives to burning fossil fuels then politicians who do not act to prevent it must stand accused not just of failing to act, but of condoning the mass poisoning of their people.

1. According to the study, ________ is probably unrelated to air pollution.
A.diabetesB.stomachachesC.AlzheimerD.artery hardening
2. The writer thinks Britain shows little sign to tackle air pollution because ________.
A.British government has been screaming for help in court
B.EU has dissuaded British government for help in court
C.British government has tried to have EU's permission for more pollution
D.The government firmly refused to act in accordance with the clean air guideline.
3. What is the writer's attitude toward the new draft?
A.Britain will implement it faster than other major developed economies.
B.It presents a practical way to end pollution from vehicles.
C.Its goal will be achieved at the price of massive health cost.
D.It's aiming too low when more pollution is expected.
4. What can be inferred from the article?
A.Government officials should feel disgraced for non-action as leaders.
B.The government should cover the bills for air pollution and related diseases.
C.Oil companies should not be held accountable for the international scandal.
D.British government is an irresponsible one for encouraging people to use vehicles.

文章大意:本文是一篇说明文。文章主要介绍了北极驯鹿的眼睛会随着季节变化而改变颜色,从而适应环境中的光线量,而且它们拥有紫外线视觉,能够在雪地中更好地发现食物和天敌,但是人工照明的使用对驯鹿敏感的眼睛构成了潜在的威胁,我们应当保护驯鹿免受光污染。

8 . On Christmas Eve, a team of reindeer (驯鹿) will help Santa Claus deliver gifts to children all around the world. The reindeer, led by their fearless leader Rudolph, won’t be the only ones doing something special. Back in the highest Arctic, their cousins have a remarkable ability changing their eye color.

During the summer months, when the days are long and the sun is bright, reindeer’s tapetum lucidum (荧光膜), a mirror-like layer at the back of their eye, appears golden, which helps bounce the majority of light off the eyes, effectively acting like a pair of natural sunglasses. As winter comes, and the days become shorter and darker, the tapetum lucidum turns blue to absorb more light, allowing reindeer to improve their night vision and see clear in low light conditions.

With these adaptations, reindeer can adapt and thrive in one of the harshest environments on Earth. Unlike humans, reindeer can see well into the shorter Ultra Violet (UV) range. This UV vision enables them to spot food and predators more effectively in the snowy landscape. Lichens, a key part of their winter diet, absorb UV, so they show up dark against UV-reflecting white snow. Wolf and polar bear fur also absorb UV, so instead of disappearing against snow they pop out in high contrast, allowing reindeer to spot potential threats from a distance.

Reindeer change their eyes by adjusting their tapetum lucidum, which is made of collagen fibers. In winter, the collagen fibers become packed tighter, causing the tapetum lucidum to mainly reflect blue light. This change happens when reindeer dilate their pupils (瞳孔). In summer, the reindeer’s pupils return to a smaller size, which helps reindeer reduce the amount of light entering the eye.

But their unique adaptation may hurt them. Today, the increasing use of artificial lighting, especially during the winter months, poses a potential threat to their sensitive eyes. It can make reindeer lose their way, affecting their ability to survive in their challenging environment. So it is crucial for us to be mindful of our use of electricity and make efforts to minimize light pollution to ensure the well-being and survival of these magnificent creatures.

1. What do we know from paragraph 2?
A.The shape of reindeer’s eyes varies with seasons.
B.It is difficult for reindeer to live in low light conditions.
C.The tapetum lucidum helps reindeer adapt to seasonal changes.
D.Reindeer’s eyes appear golden in winter while blue in summer.
2. What is the use of UV vision for reindeer?
A.To help them see clear in dark nights.
B.To distinguish food of different colors quickly.
C.To protect their eyes from harsh sunlight in summer.
D.To better locate food and enemies during snowy days.
3. What does the underlined word “dilate” in paragraph 4 probably mean?
A.Relax.B.Expand.C.Narrow.D.Hide.
4. What is the purpose of the last paragraph?
A.To call on people to protect reindeer from light pollution.
B.To show the reasons for the decline in reindeer population.
C.To present humans’ great efforts to reduce artificial lighting.
D.To prove reindeer’s strong adaptability to harsh environments.

文章大意:这是一篇说明文。随着海洋中塑料垃圾的增多,科学家们正试图通过水母的黏液研究解决海洋中微塑料的方法。

9 . Of all the weird and wonderful creatures living under the sea, perhaps the strangest are jellyfish—those rubbery, cone-shaped creatures found floating in the water, their long tentacles trailing behind.

Some jellyfish species have a bad reputation for scaring away tourists, clogging up fishing nets, and even blocking power station pipes. But with more and more plastic rubbish ending up in the sea, these days you’re as likely to swim into a plastic bag as a jellyfish. Now scientific research is discovering that these rubbery sea creatures might provide an answer—a sticky solution to the problem of plastic pollution.

In recent years, tiny pieces of plastic called microplastic have been a significant problem for the world’s seas and oceans. These plastics are not visible to the eye and aren’t caught by seawater treatment plants due to their small size, so they enter our system and harm our health. They’ve been found in many places—in Arctic ice, at the bottom of the sea and even inside animals. Slovenian scientist, Dr Ana Rotter, heads GoJelly, a European research team of jellyfish ecologists looking into the problem.

Microplastics, plastics in general, are becoming an increasing problem. Dr Ana Rotter says when she was a child, people were more environmentally friendly—not harmful to the environment or having the least possible impact on it. At that time, there were very few single-use plastics—plastic items, like spoons and forks, designed to be used just once, then thrown away. The situation since then has changed dramatically. In fact, there’s been such an increase in microplastics that today the UN lists plastic pollution as one of the world’s top environmental threats.

But how do jellyfish fit into the story? Well, it’s the ‘jelly’ part of jellyfish, and specifically their sticky, jelly-like mucus that is key. Jellyfish produce a thick, sticky liquid called mucus. Dr Ana Rotter has discovered that this mucus has strong absorptive capabilities—it can absorb, take in liquids and other substances. One of the substances jellyfish mucus absorbs are the particles that make up microplastics.

Dr Rotter’s research is still in the early stages, but it’s hoped that jellyfish mucus could hold the key to a future free of microplastic polluted oceans. Scientists are hoping that the mucus’s absorptive properties—its abilities to absorb liquids and other substances and hold them, will allow it to trap particles of plastic floating in the sea. By trapping these, the mucus acts like a magnet—an object that attracts certain materials, like metal, but in this case, microplastic waste.

1. Paragraph 3 mainly talks about ________.
A.where microplastics can be found
B.why microplastics can harm our health
C.what problems the seas and oceans are facing
D.how the research was carried out by the scientist
2. What can we learn from this passage?
A.Jellyfish species cause a great threat to the sea.
B.Jellyfish species like to swim and live in plastic bags.
C.Jellyfish mucus can attract metals and break them down.
D.Jellyfish mucus can absorb liquids and some other substances.
3. What does the underlined word “properties” in Paragraph 6 most probably mean?
A.Qualities.B.Substances.C.Choices.D.Materials.
4. What is the author’s purpose in writing this passage?
A.To show the harm that sea and ocean pollution brings to human beings.
B.To introduce the living habits of the weird and wonderful creatures in the sea.
C.To provide a new method for collecting data on environmental threats in the sea.
D.To inform a promising scientific finding for dealing with plastic pollution in the sea.

文章大意:本文是一篇说明文。文章介绍了了目前发展清洁能源的大背景下需要开采锂,但这一过程实际上代价高昂,而且可能严重破坏环境,我们需要考虑到这一潜在的威胁。

10 . Lithium (锂) is called “white gold” for good reason. The metal’s value has been growing sharply over the last several years, in a large part because it is an essential part of batteries as well as several key sustainable technologies where energy storage is of huge significance. As electric cars, wind and solar power have grown into major players in the energy industry, lithium has become key to engineering a future free of fossil (化石) fuels.

But acquiring lithium comes at an enormous cost. It often works like this: Water containing lithium is delivered to the surface from underground and mixed with fresh water. The mixture then sits in pools to get rid of water, leaving the rest of its contents behind as brightly colored “mud”. Then heat and chemical reactions are used to get lithium from that, changing it into powder which is then packaged and shipped to buyers around the world.

Any accident that releases mine contents into surrounding communities or the groundwater supply could have unimaginable long-term impacts. To be specific, indigenous (土著的) communities often bear the damage, and political leaders have typically given little weight to their concerns. In Arizona, for example, an expanding lithium mine is threatening the Hualapai Tribe’s cultural and historic sites. Recently, mining lithium and other precious metals has brought about conflict: How do you ensure the availability of materials essential to the future of renewables while protecting those communities’ rights?

Mining of the metal is expected to increase dramatically in coming years. Over time, experts say, that will reduce greenhouse gas emissions (排放) by making electric cars more affordable and, therefore, more popular. As environmentally conscious consumers buy electric cars in ever-greater numbers, it’s important to be aware of the dirty process that powers those clean air vehicles.

1. What does the author’s intention of writing Paragraph 1?
A.To introduce the background of an event.B.To explain a complex industrial theory.
C.To describe a noticeable recent tendency.D.To predict the future of a main technology.
2. Which may cause enormous environmental damage?
A.Unexpected material leak.B.Violent chemical reactions.
C.Wrong political decisions.D.Lithium mine expansion.
3. What’s the author’s attitude towards mining lithium?
A.Intolerant.B.Uncaring.C.Favorable.D.Objective.
4. What’s the most suitable title for the text?
A.High Expense of Lithium MiningB.Potential Benefit of Using Lithium
C.Hidden Threat behind Clean EnergyD.Bright Future of Renewable Resources
