1 . Vast lands of America are dominated by corn, nearly 100macres of it, stretching from Ohio to the Dakotas. What once was forest today produces the corn that feeds people, cattle and, when made into ethanol (乙醇), cars.

Now, the nation’s airlines want to power their planes with corn, too. United Airlines signed a deal with a Nebraska ethanol company to buy enough sustainable fuel, to power 50,000 flights a year. The government could decide on its tax incentives (税收激励) for the industry as soon as December. “Mark my words, the next 20 years, corn farmers are going to provide 95% of all the sustainable airline fuel,” President Biden said in July.

The airlines’ ambitious goal would likely require nearly doubling ethanol production, which airlines say, with great expectation, would decrease their greenhouse gas emissions. If they succeed, it could transform America’s Corn Belt, stimulating farmers and ethanol producers, but potentially further damaging one of the nation’s most important resources: groundwater.

Corn requires a lot of water to grow and it can take hundreds of gallons to produce a single gallon of ethanol. But as airlines take the idea of ethanol, the vital groundwater faces serious risks. “We’re on track to massively increase water usage without any real sense of how sensitive our groundwater is,” said Jeffrey Broberg, who is concerned about groundwater in Minnesota, a major corn state.

The Department of Energy said in a statement that “water use is a critical part of the conversation surrounding bio-energy sustainability”. It pointed to a 2022 department study that concluded that the United States could significantly reduce pressure on groundwater by shifting fuel production away from water-intensive crops like corn, instead growing more crops that don’t require irrigation (灌溉), like various types of straw, grasses and trees. Hopefully, a better approach will be soon studied and adopted.

2 . In the northernmost edge of Colombia sits the coastal town of Acandí. Access to the town is only by water or air; there is no road that leads there. The residents there are faced with the struggles of balancing livelihoods while protecting biodiversity.

In the past, traditional community fishing methods, passed down by the elders, focused on the reasonable fishing and management of resources. However, the introduction of large-scale trawling vessels(拖网渔船) decades ago gradually depleted the area’s fishing resources, leading to damage to marine(海洋的) life seriously.

Jesús Antonio Julio Cuestas, who serves in the region’s conservation and management of marine resources, stresses the bad impact of these developments and calls for new fishing techniques. “Fishing and conservation co-exist as long as we have good management practices and reasonable use of our fishing resources,” says Cuestas. He and other officials actively monitor fishing activities in Acandí. Each morning, they visit the fish markets to gather data on fishery resources—including prices and sizes—to monitor the state of the local fishing industry.

Along with Cuestas, the fishers work to reduce their impact on the marine ecosystem. By changing fishing methods and adopting new practices, they aim for a more balanced approach to fishing. “This year the local fishermen have not used the trawl net s that were causing the death of the leatherback sea turtles,” explains Cuestas proudly. Changes include the efforts of boats to protect the seagrass that serves as feeding grounds for marine life and an end to fishers throwing net s where turtles lay their eggs.

This marine reserve in Acandí, Cuestas believes, is their greatest treasure. He attaches great importance to working together with local residents to improve the quality of life while preserving the marine ecosystem. By doing so, he imagines a picture where individuals from the fishing community can pursue various careers, such as engineers or lawyers, proudly stating that they are the products of the fishing tradition in Acandí.

1. What does the underlined word “depleted” in paragraph 2 mean?

A．Reused.	B．Restored.
C．Explored.	D．Reduced.

2. Why does Julio Cuestas call for new fishing techniques?

A．To cut down on the costs of fishing.

B．To improve the income of local residents.

C．To promote the well-being of marine wildlife.

4 . In recent years, studies have suggested how the bisphenol A (BPA) in some food-packaging plastics has been linked to various health problems including heart disease and developmental difficulties in children. Scientists are thus developing a more harmless alternative, and it’s made from tomato waste which would otherwise be got rid of.

However, BPA is still widely used in the plastic coatings which are applied to the inside of metal food packaging such as cans. These smooth waterproof coatings help protect the metal from corrosion (腐蚀), plus they keep the food from sticking to the inside of the container.

Building on previous studies, an international team has researched a type of agricultural waste known as tomato pomace. This material typically consists of tomato skins, seeds and stems, which are left over after the fruits have been processed for use in foods such as sauces or juices. Ordinarily, the pomace is simply dumped in a landfill, burned, or at best composted. It may also be used in animal feed, although it doesn’t have much nutritional value.

The scientists started by drying tomato pomace — first in the sun for three days, then in a 60℃ oven for 16 hours — after which they grounded it into a powder. That powder was subsequently mixed with a sodium hydroxide solution (溶液), which was then heated at 100℃ for four hours. After repeatedly filtering that solution to remove the sodium hydroxide, the researchers were left a lipid. That lipid was then mixed into an ethyl alcohol solution which was sprayed onto samples of some metal. Once the spray had dried and the samples had been heated in a 200℃ oven for 10 to 60 minutes, the result was a polymerized lacquer coating which proved to be very effective at protecting the metal.

The scientists now plan on testing the coating on actual cans. “We would take tomato sauce, and other foods that are usually sold in cans, and we would sterilize them, put them in tins and check if they withstand real conditions,” said a scientist.

1. Which of the following is the most likely to use the plastic coating?

A．A pot full of water.

5 . Researchers and environmentalists have been pushing for clean energy, as well, contending with the rising threat of climate change. An increasingly researched renewable resource is called Ocean Thermal Energy Conversion (OTEC), in which the sea’s temperature variations are used to produce power. On the surface of the ocean, the temperatures are much warmer compared to the seafloor. It gets considerably colder the deeper you go because the sunlight cannot reach the bottom. These temperature differences are most noticeable in the summer when the sun is present for a majority of the hours of the day. To put it simply, OTEC uses a series of pipes that take the cooler water out in the depths of the ocean. The warm water on the ocean’s surface helps heat the cool water, which then vaporizes (蒸发) a fluid, and as a result, turns a turbine (涡轮机) to produce electricity.

Three types of ocean heat renewable energy systems are being developed and researched. An OTEC closed-cycle is perhaps the most common and well-researched, consisting of a condenser (冷凝器), evaporator, pumps, turbine and generator. There are also open systems and hybrid systems.

Systems work by pumping the warmer surface water through an evaporator containing a working fluid with a low boiling point, such as ammonia. Once the fluid vaporizes, it is used to drive a turbine and generator. From there, the vaporized fluid turns back into a liquid through a condenser, cooled by the cold, deep ocean water that pumps up from the depths. The OTEC systems that use seawater can use condensation to make water without salt.

OTEC systems need to place technology about 1 kilometer below the surface of the water. The cold water intake pipe is in the deepest area, and the piping where warm water enters is above sea level. The pumps are needed to move warm water into the system, and a heat exchanger is required to evaporate the fluid. Condensers condense the steam produced in the system, and a marker keeps the entire system afloat.

Energy is essential for almost all human activities. If the world wants to avoid an energy crisis, people need to begin relying on renewable energy. Fortunately, the three types of OTEC can provide energy for large populations.

1. What does OTEC technology depend mainly on to generate renewable power?

A．The depths of the ocean.	B．The vast surface of the ocean.

7 . 阅读下面材料，根据其内容和所给段落开头语续写两段，使之构成一篇完整的短文。

One of my favourite things about spring is the arrival of different species of birds. My grandfather was a bird lover, and I picked up the birdwatching hobby at a young age, thanks to his influence. My husband John and I found it a relaxing way to enjoy nature; we like birdwatching when we go camping or hiking. Plus, I have a great love of nature photography, so when we sit out in the backyard of our home, I always have my digital camera with me. John is an artist, and he often paints the birds I photograph.

Usually when the yellow warblers (莺) come back from the south in springtime, they pass us by; we don’t typically see them hanging around our home. But not on this particular sunny day in spring. As soon as I finished my workday, I put on a light jacket and went out to the backyard to relax in my favourite way: by watching the birds.

While taking some pictures of cardinals (红衣凤头鸟) and chickadees (北美山雀) at one of our feeders, I looked up and noticed this yellow warbler in our maple tree. The tree had recently begun to bud, and the bird’s yellow feathers looked striking against the yellow blooms, so I took this photo. Our backyard has a variety of trees and between my husband and me, we’ve documented almost 40 different species of birds. I’ve photographed most of them, but some can be a bit camera shy so I also keep a written list of what we see. Our more common visitors are cardinals, chickadees, hummingbirds and various sparrows.

8 . New research from the University of Portsmouth has shown a marked increase in shipping in the North East Atlantic. Scientists now warn that more monitoring is required to help protect sea life.

Researchers at the University of Ponsmouth have discovered that rates (率) of shipping in the North East Atlantic area rose by 34 per cent in a five-year period. The research is the first detailed survey of shipping activity in the North East Atlantic. Researchers used data from over 530 million vessel (船) positions recorded by Automatic Identification System(AIS). They looked at the change in shipping between 2013 and 2017 across ten different vessel types. In total the study area covered 1.1 million km², including waters off Belgium, Denmark, France, Germany,Iceland, Ireland, The Netherlands, Norway, Portugal. Spain, and the UK.

Lead author, James Robbins said: “This change is likely to put more pressure on the marine (海洋的) environment, and may influence the protection of at-risk species. Renewed monitoring effort is needed to make sure that protective measures are enough to save species under threat in a changing environment.”

Some of the greatest shipping increases were found in areas close to the Spanish coast. The Espacio Marino de la Costa da Morte saw a rise of 413 percent in vessel activity. It is an area used to protect seabirds.

Dr. Sarah Marley, Visiting Researcher at the University of Portsmouth, said: “Shipping is the most widespread human activity in our oceans, carrying a set of threats-from unnoticeable effects like underwater noise pollution to serious results when ships hit whales.”

Professor Alex Ford. from the University’s Institute of Marine Sciences, said: “Given the well-documented effects that shipping can have on the marine environment, it is necessary that this situation continues to be monitored-particularly in areas used to protect vulnerable (脆弱的) species which may already be under pressure.”

1. What can we say about the new research?

A．It started in 2013.	B．It is the first of its kind.
C．It was carried out by AIS.	D．It covers the whole Atlantic.

2. What do the underlined words “This change” in paragraph 3 refer to ?

D．Sea life needs better protection from an increase in shipping

9 . California has been using recycled wastewater for many years. A team has used it to make ice surfaces for the game of hockey(冰球运动). It has been used to make snow for the sport of skiing. And farmers use it to water their crops. But it has not been used directly for drinking water.

Recently, California officials approved new rules to let water agencies recycle wastewater and put it right back into the pipes that carry drinking water to homes, schools, and businesses. It is a big step for California.

California’s new rules would let—but not require—water agencies to take wastewater, treat it, and then put it right back into the drinking water system. That means proving to people that recycled water is not only safe to drink but also not dirty. California would be just the second US state to permit this, following Colorado. It has taken officials more than 10 years to develop these rules, a process that included several studies by independent groups of scientists.

A project in San Diego is aiming to produce nearly half of the city’s water through recycling wastewater by 2035. And the Metropolitan Water District of Southern California aims to produce up to nearly 570 million liters(升)a day for its 19 million people. Adel Hagekhalil is with Metropolitan Water. He said the new rules will permit new projects that have not yet been considered.

California’s new rules require the wastewater be treated for all bacteria and viruses, even if they are not present in the wastewater. In fact, the treatment is so intense that it removes all of the minerals that make fresh drinking water taste good. That means the minerals need to be added back at the end of the process. Polhemus is a director of the drinking water group for the California Water Resources Control Board. “It’s at the same drinking water quality, and probably better in many instances,” he said, adding that it takes time and money to build these treatment centers. So, they will only be available for bigger cities at first.

1. What does paragraph 1 mainly tell us about the recycled wastewater?

A．Its qualities.	B．Its functions.
C．Its target users.	D．Its disadvantages.

2. What do California and Colorado have in common?

A．They made some new rules on pollution.

B．They spent ten years recycling wastewater.

C．They tried to make wastewater safe to drink.

D．They requested water agencies to speed up treating water.

3. What is Polhemus’s attitude to turning recycled wastewater to drinking water?

A．Doubtful.

B．Favorable.

C．Pessimistic.

D．Indifferent.

4. What is the best title for the text?

A．The Process of Recycling Wastewater Is Complicated

B．California Tries to Reduce the Wastewater Generation

C．California Permits Turning Wastewater to Drinking Water

D．New Wastewater Treatment Projects Have Been Approved

10 . You may not be able to change your school’s environmental policy, but you can be the change you want to see in the world. Going eco-friendly can raise awareness of environmental issues. Here are some ways that can help you go green.

Take notes electronically

    1    ? Use a digital device such as a laptop or table t to take your notes. This will stop paper waste and also save you a ton of money! In case you don’t have a tablet or laptop, purchase a budget-friendly device.     2    . And there are lots of devices to choose from that will do just fine for note-taking, research, and so on.

Embrace (拥抱) recycling

How many soft drink cans, papers from lecture notes, plastic water bottles, and snack food packaging does every high-school student throw away? More than we could count!     3    . Focus your attention on recycling. Most areas have curbside recycling, so make sure that you place the recycled waste in the right bin.

    4    

The emission of air pollutants from transport is one of the biggest enemies of a healthy environment. To reduce the environmental impact of transport and improve public health, use sustainable (可持续的) transport. Switch from car rides to riding a bike. Also, if you are hanging out with your friends nearby, take a walk. In addition to reducing air pollution, you’ll also keep your body healthy.

Eat some greens

You don’t have to turn into a vegetarian, but you might want to consider increasing your greens. Vegetarian meals are good for your health, and they have a lower carbon footprint. Start off by introducing a meat-free day once a week. If you don’t mind getting your hands dirty, think about growing your own fruits and vegetables.     5    .
