The clock always seems to be ticking rather too fast in the doctor's office and the queue of patients outside the door seems to be pressing rather too hard. Some say it's high time for the model of short, sharp one-to-one appointments to give way to shared medical appointments (SMAs共享医疗预约).SMAs are doctor-patient visits in which a group of patients receive patient education and counseling (咨询), physical examination and medical support in a group setting. Typically SMAs are designed to have one or more doctors attend to a group of patients who share a common illness or medical condition. In contrast to one-to-one visits, SMAS provide a longer appointment time-frame as well as the opportunity for patients to have improved access to their physicians and meanwhile pick up additional information and support from peers.However, doctors who have pioneered the shared appointment approach report that there are significant challenges involved. Dr. Sumego, director of shared medical appointments, Cleveland Clinic, identifies culture change as the most significant challenge. Physicians and nurses are trained in a model of personal service and privacy; the SMA approach is a fundamental challenge to those fixed ideas. They need shared goals and a way of testing the innovation against agreed standards. Dr. Sumego says, "The physicians may be worried about the possible chaos and efficiencies that are marketed. They also have to make the patients understand what their appointment is, and what the expectation is.""So, if an organization was looking to start shared medical appointments, I would advise them to start the buy-in from a few champion physicians, develop the work-flow and develop some experience. Provide some support behind what that best practice should look like. Create some standards so that, as the concept spreads, you can employ that experience to start the next shared medical appointments and the next."(1)What is the purpose of the SMA approach?A. To improve medical service.B. To promote doctors' reputation.C. To conduct medical research.D. To meet patients' expectation.(2)According to Dr. Sumego, what prevents the SMA approach from being widely adopted?A. Personal service.B. Fixed ideas.C. Lack of equipment.D. Shared goals.(3)What can the underlined "buy-in" in Paragraph 4 be replaced by?A. practiceB. organizationC. purchaseD. support(4)What can be learned about the SMA approach in the last paragraph?A. It is currently being questioned.B. It is impractical in some areas.C. It will enjoy wide popularity soon.D. It should be carried out step by step.【答案】(1)A(2)B(3)A(4)D【解析】【分析】本文是一篇说明文,介绍了SMAs (共享医疗预约) 模式,以及这种模式面临的挑战。

A team of international scientists is due to set off for the world's biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.Last year, part of the Larsen C ice shelf calved (崩解) away, forming a huge iceberg-A68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission."The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change," she said. "It is important that we get there quickly before the undersea environment changes as sunlight enters the water."Professor David Vaughan, science director at the BAs, said, "We need to be bold (大胆的) on this one. Larsen C is a long way south and there's lots of sea ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the sea around Antarctica and is warming some coastal waters. "Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die."There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, "At the current rate, the world's ocean will be, on average, at least 60cm higher by the end of the century." However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.(1)Why are the scientists eager to go to the iceberg?A. To study how the iceberg was formed.B. To study a newly discovered ecosystem.C. To explore a new way to prevent climate change.D. To explore the geography of the Larsen C ice shelf.(2)What do the underlined words "this one" in the fourth paragraph refer to?A. The Larsen C ice shelf.B. Climate change in Antarctica.C. The A68 iceberg with the ecosystem beneath it.D. The condition of animal species in Antarctica.(3)What can we learn about the A68 iceberg from the text?A. It is as big as London.B. It is part of an ice shelf in the Arctic.C. It will disappear in a very short time.D. It has uncovered an unknown ecosystem in Antarctica.(4)What can we infer from the last paragraph?A. There is no need to worry about climate change in Antarctica.B. The ice sheets in Greenland and Antarctica are melting at a steady rate.C. Many creatures living in deep water will die out due to climate change.D. By 2100, the sea level will have risen to a much higher level than now.【答案】(1)B(2)C(3)D(4)D【解析】【分析】本文是一篇说明文,南极地区的拉森C冰架崩解形成了一座巨大的冰山A68 iceberg。

A new study from brain researchers helps explain how the human brain evolved or changed over time, to permit people to speak and write.Michael Ullman, the lead researcher, a professor at Georgetown University Medical School in Washington, D.C, has been studying language learning for more than 20 years.Ullman says his research shows that the human brain does not have a special area or system for making language. Over time we have simply reused or co-opted (指派) parts of our brain for language. And those parts, he says, are ancient-older even than humans themselves."This study examines the theoretical framework (准则) that language is learned, stored and' processed in two ancient learning and memory systems in the brain."Ullman, Hamrick and the rest of the team looked at data from 16 other studies on language. They found that people learn language using two memory systems: declarative and procedural. Memorizing vocabulary, for example, is a declarative memory process. But learning grammar is, mostly, a procedural memory process."Declarative memory, in humans at least, is what we think of as learning memory', such as, 'Oh, remember what you said last night' or things like that. And procedural motor memory is what we often call motor memory' such as how you learn to ride a bicycle." Or, Ullman adds, "These procedural memory skills become so deeply leaned that we are no longer aware that we are doing them."However, Ullman explains that the two long-term memory systems can share tasks. And, he adds, the adult brain uses the systems to learn language a bit differently than a child's brain. "Adult language learners of a second language may use their declarative memory for using grammar patterns. They think about it purposefully. For a child, the grammar may come more naturally. They don't have to think about the grammar rules before speaking."In addition to language learners, Ullman's study could help people who have a brain injury that affects speaking and writing. This knowledge can also help those who have learning disabilities such as dyslexia (阅读障碍). People with dyslexia have difficulty recognizing words and symbols accurately.(1)How did Ullman study human's memory systems?A. By examining the brain with his team.B. By studying language learning over years.C. By comparing different languages year after year.D. By referring to data from other studies on language.(2)Which of the following is an example of "motor memory"?A. Learning to make a model plane.B. Remembering the grammar patternsC. Repeating what you heard.D. Memorizing what you read.(3)What does the underlined word "it" refer to?A. Declarative memory.B. An adult language learner.C. Using grammar patterns.D. A second language.(4)What's the main idea of the text?A. Ullman has advanced our language understanding.B. A new research helps people learn a new language.C. Learning memory is more active than motor memory.D. Human beings learn language in pre human area of brain.【答案】(1)D(2)A(3)C(4)D【解析】【分析】本文是一篇说明文,讲述Michael Ullman和他的团队的研究称人类大脑前区的为语言学习区,由此解开了人类大脑进化过程之谜。

This process prevents the virus from mixing with human cells. The scientists say it can remove the effect of the virus and block its spreading.The Joint United Nations Program on HIV/AIDS reports that worldwide, nearly 37 million people were living with HIV in 2017. The organization says the largest number of those are in developing countries. Nearly two-thirds of HIV cases are in Africa. Now there is no cure for HIV/AIDS though there have been developments in oral drug treatments to slow the progression of the disease.The new study predicts the rice-based method will lead to long-term use of the anti-HIV treatment across the developing world. Researchers said the "groundbreaking" discovery is "realistically the only way" that anti-HIV combination treatments can be produced at a cost low enough for the developing world.They say the easiest and most cost-effective way to use the rice will be to make it into a cream to be put on the skin. The HIV-fighting proteins can then enter the body through the skin. People all over the world could grow the rice and make the cream themselves. This would prevent the cost and travel required for many patients to receive treatments and medicine.The process of changing the genetic structure of food crops has been debated for some time. Critics of genetically engineered crops believe they can harm people. The scientific team says further testing is needed to ensure that the genetic engineering process does not produce any additional chemicals that could be dangerous to people.(1)What does the author intend to do in paragraph 3?A. Stress the urgency of HIV treatments.B. Provide some data about HIV.C. Remind readers of HIV prevention.D. Introduce HIV to the public.(2)In which way will the rice be used at the lowest cost?A. By transforming it into proteins.B. By adding it to an oral drug.C. By attaching it to the HIV virus.D. By processing it into a cream.(3)What can we infer about the genetic engineering process?A. It can prevent infections of HIV.B. It can produce dangerous chemicals.C. It still requires perfecting.D. It applies to the developed world.(4)From which is the text probably taken?A. A biology textbook.B. A health magazine.C. A social webpage.D. A first aid brochure.【答案】(1)A(2)D(3)C(4)B【解析】【分析】本文是一篇说明文,介绍了科学家培育出可预防艾滋病病毒感染的转基因水稻。

最新高三英语阅读理解(科普环保)题20套(带答案)含解析一、高中英语阅读理解科普环保类1.犇犇Choose the one that fits best according to the information given in the passage you have just read.While faking and fierce looks are among animals great defenses, many species know that everyone runs from a big stink (臭气) too.Vulture (秃鸳)Vultures, are street sweepers that feast on the rotting flesh of dead animals, which benefits us by ridding our highways and landscapes of animal bodies and the bacteria they might carry. When vultures feel threatened they vomit, and the smell of vomited-on dead bodies puts of most predators. Throwing up allows the vulture to fly away more quickly-and the vomit can hurt the aggressor's eyes and face.Opossum (负鼠)In some ways opossums have it easy. In order to become "dead", they don't have to fax anyone a death certificate. They just lie there with their tongues hanging out with the smell of dead flesh, sometimes for hours, effectively convincing potential predators they can find a much fresher meal elsewhere. Even if they keep getting attacked, they won't move any more than a human statue until the threat has passed.Hoatzin (磨雉)Hold your nose and meet the hoatzin, a bird of distinctions, not the least of which is that it smells like fresh cow shit. The animal mostly eats leaves and it's the only bird known to digest by fermentation, like a cow. This process is what causes its smell and has earned it the nickname the "stink birdMillipedes (千足虫)Millipedes are tricky. For starters they look wormy. Their name is deceptive, too: Their legs number about 750. Their major defense is to curl up into a ball. They, though, also release a harm eyes, and leave a horrible smell on their attackers.Sea Hare (海兔)The graceful sea hare is plain in taste in the first place, so it's not the most popular dish in the seafood chain. Nonetheless this type of sea creature has a pretty creative smell-related defense that is almost the opposite of its smelly companions on this list. The sea hare gives out a slimy, purple ink, the substance which makes food less palatable to predators.Researchers using lobsters (2-f) as model predators found that the sea blocks the lobsters receptive mechanism. In other words, the sea hare gives its attacker the equivalent of a stuffy nose so they don't know how appealing it is.(1)The sea hare defends itself from predators by ________.A. becoming plain in taste at the discovery of a predatorB. giving out purple ink to make itself invisible to predatorsC. releasing substance to make predators unable to smell itD. giving off smelly gas to try to drive predators away(2)Which of the following statements is TRUE according to the passage?A. The vulture carries bacteria so that predators dare not get close to it.B. The opossum fakes its death to avoid being targeted by predators.C. The hoatzin eats cow shit so that it is nick-named as "stink bird".D. The gas released by millipede was basically harmless.(3)The species that enjoys more than one defense mechanism is ________.A. vultureB. opossumC. millipedeD. sea hare【答案】(1)C(2)B(3)C【解析】【分析】本文是一篇说明文,介绍了一些野生动物是如何进行自身防御的。

When athletes at the 2020 Tokyo Olympics collect their medals, they'll not only be wearing something that celebrates their sporting performance, but something that symbolizes lastingness. For both the 2020 Olympics and Paralympics, organizers aim to make all of the gold, silver, and bronze medals out of used electronics. This strong message about how to make use of e-waste has gotten a lot of Japan involved.Starting in April 2017, the Japanese Olympic Committee began collecting old laptops, digital cameras, smartphones, and other abandoned electronics. The initiative (倡议) has achieved great success. Already, the quantity needed for bronze medals has been met, and they're in the homestretch for silver and gold medals, meaning the collection process can pack up at the end of March.When looking just at the number of cell phones collected, the amount of waste is shocking. In a period of about 18 months, a little over 5 million smartphones were collected thanks to cooperation with NTT DOCOMO. Japan's largest mobile phone operator allowed the public to turn in phones at their shops, which counted a lot in the project's success.After being taken apart and sorted, the small electronics underwent a smelting process to extract (提炼) all the gold, silver, and bronze elements. Thanks to this initiative, the worldwide struggle with e-waste will have a global platform. According to a study published by the United Nations University—44.7 million metric tons of e-waste were made in 2016. Only 20% of that was actually recycled. Unfortunately, this figure is set to rise significantly in the coming years, moving to 52.2 million metric tons by 2021. So while the Tokyo Olympics initiative might be just a drop in the bucket, it's a good start in showing what the public can do if they're made more aware of the issue.(1)What can be learnt about Tokyo Olympics initiative from the passage?A. E-waste in the world is increasing significantly.B. It is easy to get elements needed from the used electronics.C. Only producers of electronics participated in the project.D. NTT DOCOMO contributed to the success of the project.(2)Which can best replace the underlined word "homestretch" in Paragraph 2?A. starting periodB. collection effortC. final stageD. hard search(3)What influence does the Tokyo Olympics initiative have?A. It offers an effective method to solve the problem of e-waste.B. It shows the power of advanced technology in daily life.C. It saves the expense spent in making all the medals.D. It encourages the public's involvement in dealing with e-waste.(4)What is the writer's attitude to the Tokyo Olympics initiative?A. PositiveB. NegativeC. AmbiguousD. Indifferent【答案】(1)D(2)C(3)D(4)A【解析】【分析】本文是一篇说明文,介绍了日本将回收利用废弃的电子产品中的金属,用于制作2020年奥运会奖牌。

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forestsin these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken inby the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone (臭氧) levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling."We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere." Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.(1)According to the new findings, taking steps to prevent northern forest fires may ________.A. result in a warming climateB. cause the forest fires to occur more frequentlyC. lead to a longer fire seasonD. protect the forests and the environment there(2)The following are all the immediate effects after a forest fire EXCEPT ________.A. large amounts of greenhouse gases enter the atmosphereB. the levels of ozone which is a type of oxygen increaseC. snow on the ground mirrors more sunlight back into spaceD. ashes from the fire fall on the ice surface and take in more radiation from the sun(3)Earlier studies about northern forest fires ________.A. analyze all aspects of how northern fires influence climateB. indicate that forest fires will pollute the atmosphereC. suggest that people should take measures to protect the environmentD. suggest that the fires will speed up climate warming(4)The underlined phrase "soak up" in the last paragraph most probably means ________.A. releasedB. absorbedC. createdD. distributed(5)From the passage we can draw a conclusion that forest fires in Alaska, Canada and Siberia may ________.A. warm the climate as the supposition goesB. allow more snow to reflect more sunlight into space and thus cool the climateC. destroy large areas of forests and pollute the far-off sea iceD. help to gain more energy rather than release more energy【答案】(1)A(2)C(3)D(4)B(5)B【解析】【分析】本文是一篇说明文,介绍了阿拉斯加、加拿大和西伯利亚的森林大火使气候变暖,科学家们已经发现,在燃烧的树木允许更多的雪将更多的阳光反射到太空的地区可能会发生冷却。

Gardeners such as Prince Charles who claim that talking to plants encourages them to grow have long been seen as a little silly. But scientists have discovered evidence which suggests the Royal may actually be right and they could be listening to him. Biologists at Tel Aviv University in Israel have found that flowers can act as a plant's "ears" to help them detect the sound of approaching insects.When the researchers played recordings of flying bees to evening primrose flowers, within three minutes the sugar concentrations in the nectar (花蜜) of its flowers increased. The fluid, produced to attract pollinating (授粉) insects, was on average 20 percent higher in flowers exposed to the buzz compared to those left in silence or exposed to higher pitched sounds. Professor Lilach Hadany, who led the study, said: "Our results document for the first time that plants can rapidly respond to pollinator sounds in an ecologically relevant way."However, Prof Hadany said a plant's ability to respond to pollinators may be weakened in city environments or beside a busy road. While plants require water, sunlight and the right temperature to grow, it is widely believed they do not have senses in the way animals do.But the study, published on the open-science website BioRxiv, suggests the efforts of gardeners who talk to their plants may not be in vain. "Plants' ability to hear has implications well beyond pollination—plants could potentially hear and respond to herbivores, other animals, the elements, and possibly other plants," Prof Hadany added.A month-long experiment conducted by the Royal Horticultural Society in 2009 found female voices appear to speed up the growth of tomatoes. The research offers a possible explanation —women's voices were at the right frequency for the plants to hear.(1)What's evening primrose flowers' response to bees' buzz?A. Longer bloom.B. Sweeter nectar.C. Brighter color.D. Less fluid.(2)Where can plants grow better according to Hadany?A. On a square.B. Beside a highway.C. In the woods.D. Along the street.(3)What can we infer from the research?A. Prince Charles proves kind of stupid.B. Plants can only potentially hear animals.C. Plants respond to sounds slowly and ecologically.D. Plants gardeners talk to frequently develop well.(4)What does the text mainly talk about?A. Flowers can hear.B. Bees are best pollinators.C. Plants can't grow without sound.D.

【英语】高三英语阅读理解(科普环保)题20套(带答案)一、高中英语阅读理解科普环保类1.犇犇阅读理解A single dose(剂量) of an experimental vaccine(疫苗) can protect mice against the Zika(寨卡) virus, raising renewed hope of a vaccine for humans, say scientists. The US team say the results, published in Nature, are "striking" and should encourage research efforts.Tests in humans could begin in months. But even if these go well, a licensed vaccine for widespread use to protect those at most risk -such as pregnant women -would still be years away, experts advise. Zika has been spreading across Central and South America and, most recently, Africa. More than 60 countries and territories now have continuing transmission(传播) of the disease, which is carried by mosquitoes. The virus causes serious birth damages during pregnancy and has been declared a global public health emergency.Now, developing a vaccine for pregnant women to protect their unborn babies is an international research priority(优先事项). US scientists from the Walter Reed Army Institute of Research, the Beth Israel Deaconess Medical Center and Harvard Medical School tested two types of Zika vaccine in mice – one based on bits of genetic(基因的) code from the virus and another that is an inactive (and therefore harmless) copy of Zika. Both worked well, protecting every mouse that was immunised against the virus. In comparison, all of the mice not given the vaccine caught Zika after they were exposed to it.Researchers say they will push ahead with developing the needed virus vaccine. There are many existing vaccines for other disease that use this type of technology, while there are relatively few DNA-based vaccines. Of course, future tests will need to check the vaccine is safe and effective in humans, as well as how long the immunity might last.(1)If the tests in humans go smoothly, .A. a vaccine for use in the laboratory will be still be years away.B. pregnant women in Africa will be the first to benefit from the vaccine.C. a licensed vaccine will still not be accessible in a short term.D. The Zika virus will cause less serious birth defects during pregnancy in months.(2)Which of the following statements is NOT true?A. many countries are actively involved in the research of the Zika vaccine.B. US scientists have tested more than two types of Zika vaccine in mice.C. None of the mice given the vaccine caught Zika.D. It is still unknown whether the vaccine is safe and effective.(3)Which can be the best title for the passage?A. Zika vaccine 'works very well' in miceB. Zika vaccine still has a long way to goC. International researches into Zika have paid offD. More attention has been paid to Zika vaccine【答案】(1)C(2)B(3)A【解析】【分析】本文是一篇说明文,介绍了科学家发现一种实验性疫苗可以保护小鼠免受寨卡病毒侵袭。
(1)考查细节理解。
根据第二段中的"But even if these go well, a licensed vaccine for widespread use to protect those at most risk -such as pregnant women -would still be years away"可知,但是,即使这些进展顺利,一种广泛用于保护高危人群的授权疫苗仍需数年时间,也就是说如果人体试验进展顺利的话,短期内仍无法获得授权疫苗,故选C。
(2)考查细节理解。
根据第三段中的"US scientists from the Walter Reed Army Institute of Research, the Beth Israel Deaconess Medical Center and Harvard Medical School tested two types of Zika vaccine in mice"可知,美国科学家在白鼠身上只测试了两种而不是两种以上的寨卡病毒,故选B。
(3)考查主旨大意。
根据第一段中的"A single dose(剂量) of an experimental vaccine(疫苗) can protect mice against the Zika(寨卡) virus,"可知,一种实验性疫苗可以保护小鼠免受寨卡病毒侵袭,由此可知,本文主要介绍的是寨卡病毒疫苗对小白鼠非常有效,故选A。
【点评】本题考点涉及细节理解和主旨大意两个题型的考查,是一篇科研类阅读,考生需要准确掌握细节信息,同时根据上下文进行推理,归纳,从而选出正确答案。
2.犇犇阅读理解If plastic had been invented when the Pilgrims sailed from Plymouth, England, to North America-and their Mayflower had been stocked with bottled water and plastic- wrapped snacks, their plastic waste would likely still be around four centuries later. Atlantic waves and sunlight would have worn all that plastic into tiny bits. And those bits might still be floating around the world's oceans today, waiting to be eaten by some fish or oyster, and finally perhaps by one of us. Because plastic wasn't invented until the late 19th century, and its production only really took off around 1950, we have a mere 9.2 billion tons of the stuff to deal with. Of that, more than 6.9 billion tons have become waste. And of that waste, a surprising 6.3 billion tons never made it to a recycling bin-the figure that shocked the scientists who published the numbers in 2017.No one knows how much unrecycled plastic waste ends up in the ocean, the earth's last sink. In 2015, Jenna Jam beck a University of Georgia engineering professor, caught everyone's attention with a rough estimate between 5.3 million and 14 million tons of plastic waste each year just come from coastal regions.Meanwhile, ocean plastic is estimated to kill millions of marine(海洋的)animals every year. Nearly 700 species, including endangered ones, are known to have been affected by it. Some are harmed visibly, stuck by abandoned things made of plastic. Many more are probably harmed invisibly. Marine species of all sizes, from zooplankton to whales, now eat microplas-tics, the bits smaller than one-fifth of an inch across."This isn't a problem where we don't know what the solution is, "says Ted Siegler, a Vermont resource economist who has spent more than 25 years working with developing nations on garbage." We know how to pick up garbage. Anyone can do it. We know how to deal with it. We know how to recycle. "It's a matter of building the necessary institutions and systems, he says, ideally before the ocean turns into a thin soup of plastic.(1)Why does the author mention the Pilgrims in paragraph 1?A. To prove plastic was difficult to invent.B. To introduce what marine animals like eating.C. To tell the Pilgrims contributed a lot to the marine protection.D. To show plastic waste has a lasting effect on the ocean.(2)What's the main trouble marine animals face according to the text?A. Lacking protection.B. Being stuck by plastics.C. Being caught by humans.D. Treating plastics as food.(3)What does Ted Siegler want to tell us in the last paragraph?A. Some people don't know the solution of plastics waste.B. Plastics will turn the ocean into a soup of plastic.C. It's time to take measures to deal with plastic waste.D. People should avoid using plastics to protect the ocean.(4)From which is the text probably taken?A. A biology textbook.B. A travel brochure.C. An environmental report.D.
