（英语）高二英语阅读理解(科普环保)试题类型及其解题技巧及解析
一、高中英语阅读理解科普环保类
1．犇犇阅读下列短文，从每题所给的A、B、C、D四个选项中，选出最佳选项。

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 forests
in 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 in
by 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.

2．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

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. Women's voices improve plants' growth.
【答案】（1）B
（2）C
（3）D
（4）A
【解析】【分析】本文是一篇说明文，介绍了人与植物的交流可以促其生长。

（1）考查细节理解。

根据第二段中的“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.”可知，蜜蜂飞到夜来香花，在三分钟内其花朵花蜜的糖的浓度会增加，所以花蜜会更甜。

故选B。

（2）考查推理判断。

根据第三段中的“However, Prof Hadany said a plant's ability to respond to pollinators may be weakened in city environments or beside a busy road. ”哈达尼教授认为，植物对传粉者做出反应的能力可能会在城市环境或繁忙道路旁减弱。

3．犇犇阅读下列短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。

Throughout much of human history, man has been the measure of many, if not all, things. Lengths were divided up into feet and smaller units from the human hand. Other measures were equally characteristic. Mediterranean traders for centuries used the weight of grains of wheat to define (定义) their units of mass. The Romans used libra, forerunner of the pound, by referring to the weight of a carob (角豆树) seed.
The sizes of similarly named units could also differ. The king's foot, used in France for nearly 1, 000 years after its introduction by Charlemagne in around 790 AD, was, at 32.5cm, around a centimeter shorter than the Belgic foot, used in England until 1300.Greek, Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos, Nor was there agreement on such things within countries. In France, where there was no unified (统一的) measurement system at the national level, the situation was particularly terrible. The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south.
Although John Wilkins, an Englishman, first put forward a decimal system (十进制) of measurement in 1668, it was the French who in 1799 made it law. The Système International d'Unités (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shake-up yet.
At a meeting in Versailles, France, on November 16th, 2018, the world's measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常数).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20th2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.
（1）What does Paragraph 1 mainly tell us?
A.Pound went before libra in measurement.
B.Different things used to be adopted as measures.
C.Grains were accepted as measures by the Romans.
D.Fixed measurement systems were gradually formed.
（2）How does the author develop the second paragraph?
A.In time order.
B.By analysis.
C.In space order.
D.By comparison.
（3）Which of the following countries used SI as an official measurement?
A.France.
B.Liberia.
C.America.
D.Myanmar.
（4）What will the world's measurement bodies achieve at the meeting held in Versailles?
A.They will come up with seven new SI units.
B.They will set May 20th as a new international festival.
C.They will redefine four SI units including the kilogram.
D.They will decide on a new measure used in the laboratory.

A study found wireless signals are able to pass through bags and suitcases to judge the sizes of dangerous metal objects and identify them." These items could include weapons, chemicals, laptops and batteries for bombs, "the research team said on Tuesday.
Research suggested that Wi-Fi can now be used to estimate the volume of liquids such as water, acid, alcohol and other chemicals for explosive material. The study led by researchers at the Wireless Information Network Laboratory (WINLAB) in the School. of Engineering showed a wireless device with two to three antennas(天线)that could be fitted in existing Wi-Fi networks. The detection system analyzes what happens when wireless signals go through and bounce off objects or materials. The approach, which the paper states, works by separating the wireless interference(干扰)caused by two factors of objects-the material and shape." Most dangerous objects such as weapons are usually metal or liquid, which have significant interference," researchers said.
When it was tested on a backpack, the accuracy rate topped 95 percent. "But the accuracy dropped to about 90 percent when objects inside bags are wrapped. And the tech could save lives if used in museums, stadiums, theme parks or schools," the team said, noting its design can inspect bags or luggage without being an exposure to privacy.
It uses channel state information (CSI) that is readily available in low-cost Wi-Fi devices." This could have a great impact on protecting the public from dangerous objects," said Yingying Chen, a co-author of the study," There's a growing need for that now. In large public areas, it's hard to set up expensive screening equipment like what's in airports. Manpower is always needed to ch eck bags and we want to develop a method to try to reduce manpower.”
The peer-reviewed study, which recently won a best paper award at the 2018 IEEE Conference on Communications and Network Security, is now published online." Future work will continue to focus on ameliorating the accuracy of identifying objects and imaging shapes and volumes," researchers said.

5．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. A lifestyle magazine.
【答案】（1）D
（2）B
（3）C

6．Directions: Choose the one that fits best according to the information given in the passage you have just read.
A tiny clue found in ancient deposits has unlocked big secrets about Greenland's past and future climate. Just beyond the northwest edge of the vast Greenland Ice Sheet, researchers have discovered lake mud that have survived the last ice age. The mud, and remains of common flies in it, record two interglacial periods(间冰期)in northwest Greenland.
Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. "As far as we know, it has never been found in Greenland. We think this is the first time anyone has reported it in ancient deposits or modern lakes there," Axford said. "We were really surprised to see how far north it migrated (迁徙)."
This new information could help researchers better measure Greenland's sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. Those models could then improve predictions of how Greenland's ice sheet might respond to man-made global warming. After all, Greenland covers 80 per cent of the Arctic country and holds enough ice to equal 20 feet of global sea level. "Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world," said Yarrow Axford, an associate professor in the team. "One of the big uncertainties in climate science is how fast the Earth changes when it gets warmer. Geology gives us an opportunity to see what happened when the Earth was warmer than today," said Axford.
People might be surprised to see how today's Greenland looked during the last two interglacial periods. During the Last Interglacial, global sea levels increased by 15 to 30 feet, largely due to thinning of Greenland and Antarctica's ice sheets. However, now researchers believe northern Greenland's ice sheet experienced stronger warming than previously thought, which could mean that Greenland is more responsible for that sea-level rise.
Finding lake deposits older than about 10,000 years, however, has been historically very difficult in Greenland. To measure these ancient temperatures, researchers look to ice cores (冰核) and lake deposits. Since ice and lake deposits form by a gradual buildup on annual layers of snow or mud, these cores contain history of the past. By looking through the layers, researchers can obtain climate clues from centuries ago.
（1）Why are the remains of flies mentioned in the first two paragraphs?
A.They serve as evidence that there is still life in the Northwest Greenland.
B.They were one of the many ancient lives that were left in the Greenland mud.
C.They are indicators that Greenland was much warmer than previously thought.
D.They help the researchers realize that there was once a warm period in the Arctic.
（2）The new information about Greenland is important because______________.
A.researchers have no idea how to measure Greenland's warming speed
B.it can help researchers better predict Greenland's response to warming
C.people should be more sensitive to the changes in the ice in Greenland
D.it is uncertain how fast the Earth changes with man-made global warming
（3）Which of the following can be inferred from the passage?
A.It is easier for today's scientists to find ancient lake deposits.
B.People are surprised at the landscape feature of Greenland today.
C.Researchers measure the changing temperatures by directly examining mud.
D.Greenland holds enough ice that might one day threaten life in coastal cities.
（4）Which do you think is the best title of the passage?
A.Greenland Used to Be Much Greener
B.Earth Once Experienced Warm Periods
C.Coastal Cities Warned of Coming Disasters
D.Northwest Greenland, A Perfect Destination
【答案】（1）C

【解析】【分析】本文是一篇说明文，介绍了在古代沉积物中发现的一条微小线索揭开了格陵兰岛过去和未来气候的大秘密。

就在广阔的格陵兰冰原的西北边缘，研究人员发现了在最后一个冰河时代幸存下来的湖泥。

现在研究人员认为，格陵兰北部的冰盖经历了比之前认为的更强烈的变暖。

（1）考查推理判断。

根据第一段中的“The mud, and remains of common flies in it, record two interglacial periods（间冰期）in northwest Greenland.”在格陵兰岛西北部，泥浆和常见苍蝇的残骸记录了两次间冰期；以及第二段中的“Although researchers have long known these two periods—the early Holocene and Last Interglacial—experienced warming in the Arctic, the mix of fly species shows that Greenland was even warmer than previously thought. ”尽管研究人员很早就知道这两个时期——全新世早期和最后一次间冰期——在北极经历了变暖，但混合的蝇类表明格陵兰岛甚至比之前认为的还要热。

可知，在前两段中提到苍蝇的残骸是为
了证明格陵兰岛的温度比之前认为的要高得多。

故选C。

（2）考查细节理解。

根据第三段中的“This new information co uld help researchers better measure Greenland's sensitivity to warming, by testing and improving models of climate and ice sheet behaviour. ”可知，这些新信息可以帮助研究人员更好地测量格陵兰岛对气候变暖的敏感性。

故选B。

（3）考查细节理解。

根据第三段中的“After all, Greenland covers 80 per cent of the Arctic co untry and holds enough ice to equal 20 feet of global sea level. ‘Northwest Greenland might feel really remote, but what happens to that ice sheet is going to matter to everyone in every coastal city around the world,’” 可知，格陵兰岛覆盖了这个北极国家的80%，拥有相当于全球海平面20英尺的冰。

“格陵兰西北部可能真的感觉很遥远，但冰盖的变化将关系到世界上每个沿海城市的每个人。

”故选D。

（4）考查主旨大意。

本文通过最新的发现——最后一个冰河时代幸存下来的湖泥及湖泥中的苍蝇残骸及其相关研究说明格陵兰岛之前可能更暖和。

因此，本文的最佳标题应为“格陵兰岛曾经更加绿色”。

故选A。

7．阅读理解
Imagine your clothing could release enough heat to keep you warm and cozy, allowing you to stay comfortable in a cooler room. Or, picture a car windshield that stores the sun's energy and then releases it as heat to make the ice on the windshield disappear.
According to a team of researchers at MIT, both cases may be possible before long, thanks to a new material that can store solar energy during the day and release it later as heat. This transparent polymer film could be applied to many different surfaces, such as window glass or clothing.
Solar energy is only available about half the time we need it — during daylight. For the sun to become a major power provider for human needs, there has to be an efficient way to save it up for use during nighttime and stormy days. Most such efforts have focused on storing and recovering solar energy in the form of electricity, but the new finding, by MlI professor Jeffrey Grossman, Postdoc David Zhitomirsky and graduate student Eugene Cho, could provide a highly efficient method for storing the sun's energy through a chemical reaction and releasing it later as heat.
The key to enabling long-term, stable storage of solar heat, the team said, is to store it in the form of a chemical change rather than storing the heat itself. But heat will disappear over time no matter how good the material around it is, so the team set up a chemical storage system that can keep the energy in a stable molecular configuration. When exposed to sunlight, the molecules can stay that way for long periods Then, when triggered (触发)by a very specific temperature or something else, the molecules return to their original shape , giving off heat in the process.
Such chemically-based storage materials, known as Solar Thermal Fuels(STF), have been developed before. But those earlier efforts were designed to be used in liquid solutions and not。
