Known as “wolf girl” at her West Warwick, R．I. school, Alyssa Grayson has spent much of her young life teaching others to protect and respect animals. After starting a wolf club in the second grade, Alyssa learned all she could about her favorite animals. Today, she gives presentations about protecting wolves at libraries and schools—she's even spoken at a university. In fact, she's become such a wolf expert that she was appointed as the first junior advisor to the National Wolfwatcher Coalition.
When she's not teaching others about wolves, Alyssa can be found volunteering at her local animal shelter, taking care of dogs and cats. She's also trained as a citizen scientist for FrogWatch USA. In short, Alyssa Grayson proves that you are never too young to make a difference for animals.
When asked how she got interested in saving wolves, Alyssa says, “I've loved wolves since I saw them in a movie when I was 2 or 3 years old. Then one day I saw a commercial about wolf hunting. I asked my mother why people do this, and she told me because people don't like wolves. I decided from then on that I wanted to save wolves.”
Today, wolves are hunted, trapped, or poisoned. Hunters chase wolves for miles in an airplane until the wolves are too exhausted to run anymore. Then they shoot them. The animal doesn't have a chance to escape. Animals are also trapped for their fur. They are left to suffer in a trap with no food, water, or shelter. Alyssa thinks the fur looks better on the animal in the wild, where it's meant to be, than on a human.
Alyssa believes wolves are important to our worlds. She says, “Wolves are an apex predator, which means they are at the top of the food chain. Removing them from the ecosystem is a big mistake. The ecosystem is like a chain of dominoes (多米诺骨牌)—with the apex predator as the one in front. If you were to knock down that domino, the rest of the chain would go down too.”
People usually think of “the Big Bad Wolf” when they hear about wolves. However, Alyssa says, “If they would base their thoughts on facts, not fairy tales, we wouldn't have people wanting to kill wolves.”
篇章导读：本文是一篇夹叙夹议文。文章主要讲述了阿莉莎在二年级发起一个狼俱乐部之后，开始知道她最喜欢的动物是狼。她呼吁人们客观地对待并保护这种动物，不要因为童话故事而对它存在偏见。

Drive through any suburb in the US today, and it's hard to miss the recycling bins that have become companions to America's trash cans. Recycling has become common, as people recognize the need to care for the environment. Yet most people's recycling consciousness extends only as far as paper, bottles, and cans. People seldom find themselves facing the growing problem of ewaste.
Ewaste rapidly increases as the technofashionable frequently upgrade to the most advanced devices, and the majority of them end up in landfills (垃圾填埋地). Some people who track such waste say that users throw away nearly 2 million tons of TVs, VCRs, computers, cell phones, and other electronics every year. Unless we can find a safe replacement, this ewaste may get into the ground and poison the water with dangerous toxins (毒素), such as lead, mercury, and arsenic. Burning the waste also dangerously contaminates the air.
However, ewaste often contains reusable silver, gold, and other electrical materials. Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals, which can destroy ecosystems.
A growing number of states have adopted laws to ban dumping ewaste. Still, less than a quarter of this waste will reach lawful recycling programs. Some companies advertising safe disposal in fact merely ship the waste to some developing countries, where it still ends up in landfills. These organizations prevent progress by unsafely disposing of waste in an outofsight, outofmind location.
However, the small but growing number of cities and corporations that do handle ewaste responsibly represents progress toward making the world a cleaner, better place for us all.

About 5,000 children die each day because of preventable diseases such as cholera and dysentery (痢疾), which spread when people use unclean water for drinking or cooking. A lack of water for personal health leads to the spread of totally preventable diseases like trachoma, which has blinded some six million people.
Water troubles also trap many lowincome families in a cycle of poverty and poor education and the poorest suffer most from lack of access to water. People who spend much of their time on ill health, caring for sick children, or collecting water at a distance averaging 3.75 miles a day don't have educational and economic chances to better their lives.
Agriculture is called the lion's share of clean water worldwide, using some 70 percent, and industrial use needs another 22 percent. Water areas have no political borders and nations don't always work together to share common resources, so water can be a frequent source of international problems as well.
Daybyday demand keeps growing, further draining water sources, from great rivers to groundwater. “We're going deeper into debt on our groundwater use，” Postel said, “and that has great effects on global water safety. The rate of groundwater use has doubled since 1960.”
Some of Earth's groundwater is fossil water created when Earth's climate was far different. Today such water is as limited as petrol. “But we're pumping much of them out faster than ever，” Postel explained. “Man's growing thirst also causes a major problem about water and our ecosystems. And that also creates a cost to us, to our sons and to our grandsons, not just to nature.”
篇章导读：本文是一篇说明文。水是生命之源，与人类的健康、农业等息息相关，然而在很多地区，水资源短缺已成了一个相当严峻的挑战。

College students may find a greener campus when they return to classes this fall. Some schools are repairing older buildings and constructing new ones that are better for the environment. Other steps include adding wind and solar energy systems and planting vegetable gardens.
George Washington University (GW) is a private school with 200,000 students. The university has two gardens where students volunteer their time.
Over the last ten years GW has developed projects in three main areas—climate, water and ecosystems. They have begun to create projects on the ground to address climate change. They are planning on becoming carbonneutral (平衡的) and, in fact, reducing the_footprint by forty percent by 2025, from creating solar hotwater systems on our rooftops to making our buildings much more energy efficient. The school also offers 140 different classes in sustainability (可持续性发展) and the environment.
Mark Orlouski said, “We see numbers like less than 20% of school having a green building policy five years ago and now upwards of 80% of schools having a policy, which states that their new buildings will be built in a green fashion.”
GW is located in the Foggy Bottom neighborhood of Washington. Some neighbors say that while GW is laying to be friendlier to the environment, it could also be a better friend to the neighborhood. The school has expanded quickly and there have been tensions between students and local residents.

(2018·浙江高考)Steven Stein likes to follow garbage trucks. His strange habit makes sense when you consider that he's an environmental scientist who studies how to reduce litter, including things that fall off garbage trucks as they drive down the road. What is even more interesting is that one of Stein's jobs is defending an industry behind the plastic shopping bag.
Americans use more than 100 billion thin film plastic bags every year. So many end up in tree branches or along highways that a growing number of cities do not allow them at checkouts (收银台). The bags are prohibited in some 90 cities in California, including Los Angeles. Eyeing these headwinds,_plasticbag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume.
Among the bag makers' arguments: many cities with bans still allow shoppers to purchase paper bags, which are easily recycled but require more energy to produce and transport. And while plastic bags may be ugly to look at, they represent a small percentage of all garbage on the ground today.
The industry has also taken aim at the product that has appeared as its replacement: reusable shopping bags. The stronger a reusable bag is, the longer its life and the more plasticbag use it cancels out. However, longerlasting reusable bags often require more energy to make. One study found that a cotton bag must be used at least 131 times to be better for the planet than plastic.
Environmentalists don't dispute (质疑) these points. They hope paper bags will be banned someday too and want shoppers to use the same reusable bags for years.
篇章导读：本文是一篇议论文。文章主要探讨了人们该用塑料袋还是环保袋或者两者都不使用，并分析了其原因。
1．What has Steven Stein been hired to do?
A．Help increase grocery sales.
B．Recycle the waste material.
C．Stop things falling off trucks.
D．Argue for the use of plastic bags.
答案：D 细节理解题。根据第一段最后一句并结合第二段最后一句中的“plasticbag makers are hiring scientists like Stein to make the case that their products are not as bad for the planet as most people assume”可知，塑料袋制造商雇佣Stein这样的科学家来为塑料购物袋的使用进行辩护。故选D。
2．What does the word “headwinds” in Paragraph 2 refer to?
A．Bans on plastic bags.
B．Effects of city development.
C．Headaches caused by garbage.
D．Plastic bags hung in trees.
答案：A 词义猜测题。画线词是承接其上一句的内容描述，指在包括洛杉矶在内的加利福尼亚州的90个城市，塑料袋是禁止使用的。再结合画线词后的“to make the case that their products are not as bad for the planet as most people assume”可推断出，此处headwinds指的是“bans on plastic bags”，即对塑料袋的禁令。故选A。
3．What is a disadvantage of reusable bags according to plasticbag makers?
A．They are quite expensive.
B．Replacing them can be difficult.
C．They are less strong than plastic bags.
D．Producing them requires more energy.

(2019·浙江高考)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.
篇章导读：本文是一篇调查报告。调查表明，加利福尼亚州的大树变少了，而气候变化是其中的一个主要因素。
5．What is the second paragraph mainly about?
A．The seriousness of bigtree 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.
答案：A 主旨大意题。第二段中通过列举一系列数字表明，加利福尼亚州的大树减少的严重性，故A项正确。
6．Which of the following is wellintentioned but may be bad for big trees?
A．Ecological studies of forests.
B．Banning woodcutting.
C．Limiting housing development.
D．Fire control measures.
答案：D 推理判断题。由第三段最后一句可知，控制野火的措施使得加利福尼亚州的森林里满是跟大树争夺资源的小树，初衷是为了控制野火，这是好的，实则对大树不利，故D项正确。
7．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.
答案：C 细节理解题。根据文章最后一段中的“... the biggest factors driving up water stress in the state have been rising temperatures ...”可知，水资源不足的主要原因就是气温升高，即更加温暖的气候，故C项正确。
8．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
答案：A 标题判断题。本文是一篇调查报告，第一段就点出主题：California has lost half its big trees since the 1930s。后面具体分析了加利福尼亚州大树的现状、造成大树减少的原因等，故A项作为标题最合适。

(2020·甘肃省会宁一中高三第一次月考)Petrol and diesel (柴油) cars may still dominate our roads, but their days are numbered. A recent university study found that current electric cars could be used for 87 per cent of daily car journeys in the US. That figure could rise to 98 per cent by 2020.
One hurdle to the widespread adoption of electric cars has been “range anxiety”—drivers' concerns about running out of juice on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. That said, charging points are becoming increasingly common throughout the USA.
Attitudes towards electric vehicles have changed quite considerably over the last few years. Not that long ago, electric cars were met with distrust, and their large price tags (标签) drove customers away. Thanks to improvements in battery capacity, recharging times, performance and price, the current generation of electric cars is starting to persuade critics. Plugin cars will soon give internal combustion (燃料) engine models a run for their money.
As well as advancements on the road, electric vehicles are taking to the seas and skies. Electric boats are among the oldest methods of electric travel, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrolpowered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric air travel are also being made, with Airbus and NASA among the organizations developing and testing battery powered planes. The experiments could soon make commercial electric flight a reality.
Electric vehicles do not produce any emissions. Were the US to act on the study's findings and replace 87 per cent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 per cent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim to be completely emissionfree. Even so, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

(2018·全国卷Ⅰ)We may think we're a culture that gets rid of our worn technology at the first sight of something shiny and new, but a new study shows that we keep using our old devices (装置) well after they go out of style. That's bad news for the environment—and our wallets—as these outdated devices consume much more energy than the newer ones that do the same things.
To figure out how much power these devices are using, Callie Babbitt and her colleagues at the Rochester Institute of Technology in New York tracked the environmental costs for each product throughout its life—from when its minerals are mined to when we stop using the device. This method provided a readout for how home energy use has evolved since the early 1990s. Devices were grouped by generation. Desktop computers, basic mobile phones, and boxset TVs defined 1992. Digital cameras arrived on the scene in 1997. And MP3 players, smart phones, and LCD TVs entered homes in 2002, before tablets and ereaders showed up in 2007.
As we accumulated more devices, however, we didn't throw out our old ones. “The livingroom television is replaced and gets planted in the kids' room, and suddenly one day, you have a TV in every room of the house，” said one researcher. The average number of electronic devices rose from four per household in 1992 to 13 in 2007. We're not just keeping these old devices—we continue to use them. According to the analysis of Babbitt's team, old desktop monitors and box TVs with cathode ray tubes are the worst devices with their energy consumption and contribution to greenhouse gas emissions (排放) more than doubling during the 1992 to 2007 window.
So what's the solution (解决方案)? The team's data only went up to 2007, but the researchers also explored what would happen if consumers replaced old products with new electronics that serve more than one function, such as a tablet for word processing and TV viewing. They found that more ondemand entertainment viewing on tablets instead of TVs and desktop computers could cut energy consumption by 44%.
篇章导读：本文是一篇议论文。文章讲述了新旧电子设备的差别，旧电子设备耗能高，不环保，所以作者主张使用新电子设备。
13．What does the author think of new devices?
A．They are environmentfriendly.
B．They are no better than the old.
C．They cost more to use at home.
D．They go out of style quickly.
答案：A 推理判断题。根据第一段最后一句可知，使用旧的电子设备对环境和我们的钱包都是坏消息。这些过时的设备做相同的事情要消耗比新设备更多的能源。由此推知，作者认为新电子设备环保、节能。故选A。
14．Why did Babbitt's team conduct the research?
A．To reduce the cost of minerals.
B．To test the life cycle of a product.
C．To update consumers on new technology.
D．To find out electricity consumption of the devices.
答案：D 细节理解题。根据第二段第一句中的“To figure out how much power these devices are using, ...”可知，Babbitt的团队研究的目的是为了弄清楚新旧电子设备的耗能量。故选D。
15．Which of the following uses the least energy?
A．The boxset TV. B．The tablet.
C．The LCD TV. D．The desktop computer.

(2020·陕西省部分学校第一学期摸底检测)A biologist once criticized for stealing eggs from the nests of the rarest bird in the world has been awarded the “Nobel Prize\” of conservation after his methods saved nine species from extinction.
Professor Carl Jones won the 2016 Indianapolis Prize—the highest accolade in the field of animal conservation—for his 40 years of work in Mauritius, where he saved an endangered kestrel (红隼) from becoming the next Great Auk.
When the 65－year－old first travelled to the east African island in the 1970s, he was told to close down a project to save the Mauritius kestrel. At the time there were just four left in the wild, making it the rarest bird on Earth. However, he stayed, using the techniques of captive breeding (人工繁殖), which involved snatching eggs from the birds' nests and hatching them under incubators (孵化器), prompting the mothers to lay another set of eggs in the wild.
A decade later, the number of Mauritius kestrels had soared to over 300 and today there are around 400 in the wild. The biologist has also made an effort to bring other rare species back from the edge of extinction, including the pink pigeon, echo parakeet and Rodrigues warbler.
Prof Jones was awarded the $250,000 prize at a ceremony in London.
“As a young man in my 20s, I certainly didn't enjoy the stress and the tension of the criticism I received.\” Reflecting on the start of his career, he said the Mauritius kestrel project had been seen as a “dead loss\” at the time. In the 1970s there was fierce opposition to the captive breeding techniques, with critics arguing that they were too risky and took the emphasis off breeding in the wild.
Prof Jones has devoted his whole life to his work, only becoming a father for the first time at 53. He said receiving the prize was particularly important to him, because it proved that his work to save birds was right.
