1 . Despite years of drought and water-saving policies, Californians continue to put a lot of clean, drinkable water into yards to keep the greenery alive. Now, however, Southern California officials have carried out very strict limits on outdoor water use in response to a water shortage emergency. So you may need to find other ways to keep your plants from drying in the summer sun.
How about watering them with grey water instead of clean water? Grey water is the water from showers, bathtubs, washing machines — anything that’s not filled with human waste, food or poisonous chemicals. With the right measures, grey water can be fine for most plant life.
If you’re a typical Southern Californian, you’re throwing a lot of grey water into the sewer system. Every load of clothes you wash leads to roughly 15 to 40 gallons of it, depending on your washer’s design and efficiency. Over the course of a year, thousands of gallons of soapy water ran away. That’s enough to keep a number of trees and other plants happy. And if you’re really ambitious, you can build a system that carries all of your horned grey water to the roots of your grassland, thus making your non-native grass in your yard watered regularly.
Some critics, the Los Angeles Sanitation and Environment Bureau, see grey water recycling as environmentally risky, damaging public wastewater recycling efforts and uneconomic. However, other local agencies across the state, including the Los Angeles Department of Water and Power, actively endorse grey water projects as a way to reduce water use. Supporters admit that the projects carry some risk and require great efforts, but insist that they can save clean water and help your plants.

2 . As seabird biologist Bonnie Slaton slides off a small boat and walks through high water, the brown pelicans (鹈鹕) spread their wings overhead until she reaches Raccoon Island. The narrow island is a small piece of land separating the American state of Louisiana from the Gulf of Mexico. During the seabird breeding (繁殖) season, the placer, one of the few remaining places of safety for the pelicans, is full of noise.
Twelve years ago, there were 15 low-lying islands with breeding areas for Louisiana’s state bird. However, today, only about six islands in southeastern Louisiana have brown pelican nests and the rest have disappeared underwater.
Slaton and other scientists set u cameras to observe pelican nests on the island. The cameras show that in recent years the pelicans have faced some natural disasters. The main killer of them is flooding, which can wash away all the nests, as happened in April 2021. The disappearing islands are the location of a story of successful conservation. For many years, scientists have worked to bring the pelicans beck from tally dying off.
Mike Carloss is a state wildlife biologist in Louisiana. He said he never saw brown pelicans as a child in the 1960s. Their populations had been killed by the use of DDT, a kind of farm chemical. It thinned eggshells and prevented pelicans from giving birth to young birds. The beloved birds were completely gone from Louisiana, only appearing on the state flag. But a long-running effort to save them led to the birds’ return. After DDT was stopped in the U.S. in 1972, biologists brought young pelicans from nearby Florida to let them inhabit empty islands across the Gull of Mexico again. More than 1,200 pelicans have been set free in southeastern Louisiana over 13 years.
The brown pelicans can live more than 20 years. So, the final effect of disappearing breeding areas is uncertain and it will sill take time to become clear. And the future for pelicans is uncertain on the islands.

3 . The San Diego County Water Authority has an unusual plan to use the city’s scenic San Vicente Reservoir (水库) to store solar power so it’s available after sunset. The project could help unlock America’s clean energy future.
Perhaps ten years from now, if all goes smoothly, large underground pipes will connect this lake to a new reservoir, a much smaller one, built in a nearby valley about 1100 feet higher. When the sun is high in the sky, California’s abundant solar power will pump water into that upper reservoir. It’s a way to store the electricity. When the sun goes down and solar power disappears, operators would open a valve (阀门) and the force of 8 million tons of water, falling back downhill through those same pipes, would drive machines capable of producing 500 megawatts of electricity for up to eight hours. That’s enough to power 130, 000 typical homes.
“It’s a water battery!” says Neena Kuzmich, Deputy Director of Engineering for the water authority. She says energy storage facilities like these will be increasingly important as California starts to rely more on energy from wind and solar, which produce electricity on their own schedules, without considering the demands of consumers.
Californians learned this during a heat wave this past summer. “Everybody in the state of California got a text message at 5:30 in the evening to turn off their appliances,” Kuzmich says. The sun was going down, solar generation was disappearing, and the remaining power plants, many of them burning gas, couldn’t keep up with demand. The reminder worked:People stopped using so much power, and the grid (电网) survived.
Yet earlier on that same day, there was so much solar power available that the grid couldn’t take it all. Grid operators turned away more than 2000 megawatt hours of electricity that solar generators could have delivered, enough to power a small city. That electricity was wasted. There was no way to store it for later, when operators desperately needed it.
1. What is the function of Paragraph 2?| A．To present the importance of a reservoir. | B．To recall a situation in recent ten years. |
| C．To introduce the usage of solar energy. | D．To explain a way to store electricity. |

4 . The woods are turning orange. Drifts of dry leaves are growing on forest floors and flying into street corners. From a distance, it is beautiful. But the air is still warm and summery. This turning and leaf fall is not the usual gradual preparation for winter in temperate zones(温带) but a stress response by trees trying to preserve water. We are now in a false autumn, caused by heat and drought. And it feels wrong.
There is, therefore, something deeply disturbing about such a graphic alteration of familiar rhythms, Droughts are not unknown to the UK, of course, and too many parts of the world are certainly familiar with far more severe versions. But increasingly they are occurring in the context of a climate emergency, and record-breaking heat. And the beauty of a false autumn, specifically, has an emotional effect, a deep weirdness, something mysteriously suggestive of evil or danger
Cultures across the world contain ceremonies for the propitiation(宽恕) of the weather; a sense of responsibility for the natural world—and the belief that it will punish us if we fail it—is as old as humanity. One of the reasons why the Romantic poet Samuel Taylor Coleridge’s 1798 poem The Rime of the Ancient Mariner is so effective is the directness with which it links the shooting of an albatross(信天翁)—the destruction of innocent wildlife—to a terrible change in the weather: no rain, just burning, death-dealing sun. We may not understand the mechanism, but at an instinctual(本能的) level it feels right.
And in a similar way it has not really been a surprise to hear that birds are struggling. In London, young swifts (雨燕) were seen falling out of the sky. Fewer—and too early—nuts and berries mean some animals will not live through this winter. Older trees, with their longer roots, will hopefully survive, but young trees may not—all that promises further warming. There will always be a degree of uncertainty about the causes of specific weather events, but we cannot deny that we have not taken care of the albatross. Now we must hope we are doing enough to make sure that these fearful golden days are pot an autumn of autumns.
1. According to the passage, what is a disturbing sign of “a false autumn”?| A．Tree leaves are turning orange and fall gradually in winter. |
| B．Birds are struggling to fall out of the sky in London. |
| C．People worldwide are careless of droughts and heat in the UK. |

5 . Pioneers like Harvard social ecologist Stephen Kellert were among the first to champion modern biophilic design. Kellert believed that weaving nature into living and workspaces is critical for good physical and mental health.
Humans have evolved to gravitate towards nature, Kellert noted. His principles include access to natural light, air, water, and plants. Using materials such as wood and stone, biophilic designs such as leaf or shell patterns help humans to feel closer to nature.
Biophilic designs can be seen all over the world. Examples include the Changi Airport in Singapore, with its four-storey forest garden and world’s largest indoor waterfall fed by rainwater, and the Swedish Mirror Cube Tree House Hotel, mainly made of used plywood and a lightweight aluminum frame wrapped around a tree. Incredible biophilic homes include One Central Park in Sydney, apartment blocks featuring hanging gardens on the outside. The buildings recycle their own water and a suspended (悬浮的) motorized mirror system reflects sunlight down onto gardens below. Milan’s Bosco Vertical block is perhaps even more eye-catching with its vertical forest.
Putting biophilic design to work for society could prevent millions in healthcare costs, with one study estimating annual savings of $93 million in the US alone. Hospital design in particular has historically been influenced by access to sunlight and views of nature. Modern buildings like the Khoo Teck Puat Hospital in Singapore, with its position next to the waterfall of the Yishun Pond, are closely linked with their surroundings. The hospital channels outdoor air to cool the inside, and uses reflective sunshades to direct light into the wards to brighten them and save energy.
The aim of these designs is to emphasize the human connection to nature by integrating buildings with the local environment. But how do we bring biophilia into our homes? Start with house plants. New smart home apps can also provide sensory nature experiences such as birdsong and a projected forest canopy, helping people to carve out a restful space indoors.
But perhaps the best way to transform society with biophilic designs is to start with schools. Children learn better and feel more relaxed in biophilic settings. So the Children and Nature Network is working with schools across the US to create green schoolyards for better physical and mental health and to increase opportunities for outdoor learning.
Biophilic designers are bringing nature into classrooms through natural patterns, shapes and colors, nature photography, artwork and materials like timber and stone. Fresh air flow, green walls, and aquariums all become part of a recipe for improving health and academic success.

7 . How to save planet earth
Have you ever held a product in your hands and considered the existential weight of your purchase? Beyond each price tag hides a ripple effect. It expands from soil to water ways, grocery aisle to kitchen plates, factories to fulfillment centers and mail slots to landfills. This global impact has become less hidden in the past decade, and ignoring the people downstream from us has grown increasingly difficult.
We’re more aware than ever of the mark our consumption leaves on planet Earth, which now sustains nearly 8 billion people. Somehow, humans are still pumping more than 30 gig a tons of carbon dioxide(CO2)per year into the atmosphere, despite the mountain of evidence that CO2 is the top contributor to greenhouse gases causing global warming.
Climate journalist and author Tatiana Schlossberg says even a simple trip to the supermarket can feel paralyzing in 2021. “I want to buy the local thing, but it’s not organic. Or, maybe it’s in a plastic box,” she says. In her 2019 book Inconspicuous Consumption, she ventures way beyond the store aisle and into the web of less apparent ways that humans are damaging Earth. For example, your internet use is tied to extensive carbon emissions and energy consumption.
In fact, being a good citizen on planet Earth with climate concerns, you’ve likely asked or agonized over this question: What should I do?
One of their most consistent insights may surprise you: Consumer responsibility misses the mark. “One of the major failings of the environmental movement is having everyone focus on these small things that everyone can do.” says Ayana Elizabeth Johnson-a marine biologist and co-host of the podcast How to Save a Planet.
“Individuals join together to collectively have far more power changing the system than they can as individuals,” says Anthony Leiserowitz, director of the Yale Program on Climate Change Communication.
| A．That doesn’t mean it’s none of your business. |
| B．these experts propose other key steps that every human can take toward a better future. |
| C．Similar challenge apply to use of plastics and consumption of meat and other goods. |
| D．Part of the challenge with the environmental movement is the astonishing list of things we need to change. |
| E．The solution to this problem, however, is not for you to stop using the internet, according to Schlossberg. |
| F．It’s easy to get lost in the storm of supposed answers around social media, the latest data sets and “ego-friendly” marketing campaigns. |
8 . The forest of today will not be the forests of tomorrow. Rising temperatures, trees being cut down, development and climate-change-caused disasters are changing the very makeup of the Earth’s forests, new research published in Science finds.
Older, bigger trees are being lost at an alarming rate, making the planet’s forests shorter and younger. The change is being driven at different rates by different causes in different places, the study’s authors say, but the consequences will be global.
Old growth forests absorb and store massive amounts of climate-warming CO2. They provide habitats for rare and endangered species and promote rich biodiversity. Researchers found that the world lost roughly one-third of its old growth forests between 1900 and 2015. In North America and Europe, they found that tree mortality has doubled in the past 40 years.
“Warming temperatures, wildfires, logging and insect outbreaks were among the many causes of the decline,” says Nate McDowell, the study’s lead author. “What’s perhaps more concerning is that the trajectory of all these disturbances is generally increasing over time and is expected to continue increasing in the future.” he says.
McDowell’s focus is on how trees are affected by rising temperatures, arguably the biggest driver of forest change. To get a broader understanding of how forests are changing globally, he brought in more than 20 other researchers in different fields. Together, they examined more than 160 previous studies about tree mortality and its global causes, applying current satellite data and modeling to create a look at the Earth’s changing forests to date.
“It’s not a shock, but it’s very sad,” says Kristina, an ecologist and leader of the ForestGEO Ecosystems &Climate Program who helped with the research. “We as a human society are hitting these forests so rapidly with so many different changes that they can’t keep up.” she says.
