【推荐1】What is the best part of a typical relaxing summer day? Nothing is better than sitting in an armchair with a beer and some chips in your hand, enjoying the great comfort.

The much-loved combination of beer and chips is being exploited for the first time to deal with climate change. Chips firm Walkers has adopted a technique it says will cut CO₂ emissions (排放) from its production process by 70%.

The technology will use CO₂ captured from beer processing in a brewery (啤酒厂), which is then mixed with potato waste and turned into fertilizer. It will then be spread on UK fields to feed the following year’s potato crop. Creating fertilizer normally produces high CO₂ emissions, but the technology adopted by Walkers makes fertilizer without generating CO₂. So, the beer-and-chips combination performs a double function. It stops the emission of brewery CO₂ into the atmosphere — and it saves on the CO₂ normally generated by fertilizer production.

This Creative win-win solution was developed with an approval from the UK government by a 14-employee start-up called CCm. The fertilizer was experimented on potato seed beds this year, and next year Walkers will install CCm equipment at its Leicester factory to prepare for its 2022 crop.

A decision has not yet been made on which brewery Walkers will work with on this. The new technology adds to carbon-saving techniques already under way. The firm has installed an anaerobic digester (厌氧消化池), which feeds potato waste to bacteria to produce a useful gas. The gas is burned to make electricity for the chip-frying process — so this saves on burning gas or coal.

The new system will go a step further by taking away potato “cake” left after digestion — and mixing the brewery CO₂ into it to make an enriched fertilizer which will help put carbon back into the soil as well as encouraging plant growth.

It’s an example of scientists finding ways to use CO₂ emissions which otherwise would increase the over-heating of the planet.

【推荐2】One of the questions surrounding climate change is how it might affect the food supply for a growing global population. A new study suggests that researchers have been overlooking how two key human responses to climate—how much land people choose to farm, and the number of crops they plant—will affect food production in the future. The new study focused on the Brazilian state of Mato Grosso, an emerging（新兴的）global breadbasket（产粮地区）that as of 2013 supplied 10 percent of the world’s soybeans. The researchers used variations in temperature and precipitation（降水）across the state over an eight-year period to estimate the sensitivity of the region’s agricultural production to climate change. Those historical comparisons can help in making predictions about the sensitivity of agriculture to future climate change.

The study found that, if the patterns from 2002 to 2008 hold in the future, an increase in average temperature in Mato Grosso of just 1 degree will lead to a 9 to 13 percent reduction in overall production of soy and corn. “This is worrisome given that the temperature in the study region is predicted to rise by 2 degrees by 2050,” said Avery Cohn, who led the study.

Most studies of this kind look only at the extent to which climate shocks affect crop output. But researchers can miss critical dynamics（动力）that can affect overall output, says Leah VanWey, one of the study’s senior authors. “If you look at output alone, you’re not looking at all of the information because there are economic and social changes going on as well,” said VanWey.

If output decreases, farmers may put less land area into production because it’s not profitable. Farmers may also vary the number of crops they plant in a growing season. Double cropping is common in Mato Grosso. But if the weather is bad, farmers may change their decision to plant a second crop.

1. The value of the new study lies in _________.

A．increasing the number of crops people plant

B．focusing on an emerging global breadbasket

C．making predictions about human responses to climate change

D．controlling people’s choice of their farming area and crop numbers

2. According to Avery Cohn, by 2050, the overall production of soy and corn will _________.

A．remain almost unchanged	B．decrease by more than 9%
C．increase by from 9% to 13%	D．decrease by more than 18%

3. What can we know about the similar studies mentioned in paragraph 3?

A．They can’t provide exact information to farmers.

B．They don’t take into consideration some key factors.

C．Their discouraging results largely affect overall crop output.

D．They pay too much attention to economic and social changes.

4. What is the last paragraph mainly about?

A．Farmers’ possible reactions to climate shocks.

B．Possible climate change in Mato Grosso.

C．The benefits of double cropping in Mato Grosso.

D．Farmers’ decision on planting crops in the future.

【推荐3】If we planted a lot more trees in just the right places, they could reduce the amount of carbon in the atmosphere to levels not seen since the 1920s, said study leader Jean Francois Bastin, an ecologist from the Swiss Federal Institute of Technology. After examining more than 70,000 high-quality satellite photos of trees from all over the planet, ecologists concluded that the earth could support 900 million additional hectares (公顷) of tree cover.

Bastin and his colleagues developed a computer program that estimates how much forested land could be restored both now and in a future warmer world. The team members combed through 78,774 satellite photos of a variety of ecosystems- everywhere from the thick Amazon rainforest to the dry Sahel in Africa-that had been protected from human influence. They counted every tree in every photo to assess the current tree coverage in natural environments. The researchers combined that information with data about the climate, temperature and soil conditions for each ecosystem. Then they taught their program to put it all together to determine how much tree coverage a particular area could support.

The result shows trees currently cover 2.8 billion hectares of land- but they have the potential to populate as much as 4.4 billion hectares. Right now, much of the additional 1.6 billion hectares is being used for agriculture or urban spaces. The researchers took those areas off the table and saw that the earth still has 900 million hectares ready and waiting to be restored with trees an area roughly the size of Brazil. When those trees mature, they could remove 205 gigatonnes (兆吨) of carbon from the atmosphere, the study calculated, That represents about two-thirds of the roughly 300 gigatonnes of atmospheric carbon that can be traced to human actions, they said.

Even if trees are planted in the most mindful way, other actions are still needed to fight climate change, Bastin said.

1. Why did Bastin develop a computer program?

A．To reduce air pollution in Africa.

B．To determine carbon dioxide in the air.

C．To assess the potential forested land.

D．To calculate the area of forest in the world.

2. What does the underlined phrase “combed through” in Paragraph 2 refer to?

A．Looked into.	B．Put away.
C．Brought back.	D．Took in.

3. What can we infer from what Basin said in the last paragraph?

A．Brazil has large areas to plant trees.

B．The tree cover is not enough to control greenhouse gases.

C．Trees removed two-thirds of carbon in the atmosphere.

D．Other actions are equally important compared to planting trees.

4. What is the author’s attitude towards the research result?

A．Disapproving.	B．Doubtful.
C．Supportive.	D．Objective.

【推荐1】Digital health refers to the system of interconnected devices that can monitor and report important health information. Doctors can use that information to ensure that your treatment is tailor-made to your situation.

The most useful aspect of digital health is the ability to constantly and accurately monitor vital information. Wearable devices can record your blood pressure or the rhythm your heartbeat. The information is then accessible remotely through the Internet , so your doctor has a wealth of information about your daily health. Your doctor can use that information remotely to make changes to your treatment at any time.

A survey conducted by the company Lightico in March 2020, reveals how satisfied consumers are with this type of remote care. Forty-one percent said that the remote treatment they had received by means of digital devices and the Internet was either “good” or “excellent”. The same positive attitude toward digital health can be seen among investors. In the first quarter of 2020 , 3.1 billion dollars in new investment poured into the digital health industry , setting a new investment record.

Advances in digital health, however also bring privacy concerns. Information regarding your health could be used for advertising or marketing , for example. If health records are accessible online, protecting your information from theft and unauthorized use might be difficult. But if managed properly, the benefits of digital health could certainly outweigh the risks.

When Chinese researchers successfully figured out the genetic structure of the novel coronavirus in January, many people thought a vaccine(疫苗) would soon follow.       1         

First, scientists must work together to understand the structure of the virus and develop potential vaccines to fight against it.       2       After passing animal tasting, clinical trials of the vaccine are then done on humans. Finally the vaccine needs to be approved by officials before it can be made available to the public. All of the steps are necessary to make sure that the new vaccine is safe for people to use.       3       With technological advancements and government funding (资金), the time it takes to develop vaccines can be reduce.

CEPI, an international organization that develops vaccine, for example, is funding programs that focus on making a vaccine for the novel coronavirus. About 35 companies and academic institutions, including the US company Moderna, funded by CEPI, are searching for a COVID-19 vaccine.       4       Once a vaccine is ready, 100 million doses (剂量) could be made within a year, according to Modena’s CEO Stephane Bancel.

    5       Not only do they help to save individual lives, but they also help the local and even the global community.

A．This is why a vaccine is developed.

B．But that’s a lot easier said than done.

C．However, experts say vaccines are unlikely to be available

D．Once these first vaccines are made, they are tested on animals.

E．Sometimes, this process can take as long as 10 to 15 years to complete.

F．Even though vaccines take a long time to develop, they are very important.

G．A few have begun testing in animals, while Moderna’s attempt has started human trials.

【推荐3】Everything about nuclear energy seems terrifically big: the cost, construction and decommissioning -- and the fears of something going badly wrong. The future, however, may well be much smaller. Dozens of companies are working on a new generation of reactors that, they promise, can deliver nuclear power at lower cost and reduced risk. These small - scale plants will on average generate between 50 MW and 300 MW of power compared with the 1,000 MW - plus from a conventional rector. They will draw on modular manufacturing techniques that will reduce construction risk, which has plagued larger 0 scale projects. Supporters believe these advanced   modular reactors (AMRs) -- most of which will not be commercial until the 2030s -- are critical if atomic power is to compete against the rapidly falling costs of solar and wind.

“The physics hasn’t changed. it’s about much cleverer design that offers much needed flexibility in terms of operation,” said Tim Stone, long-term industry adviser and chairman of Nuclear Risk Insurers, which insures nuclear sites in the UK. Since the Fukushima meltdown in Japan in 2011, safety fears have threatened nuclear power. But the biggest obstacle today is economic. In western Europe, just three plants are under construction: in the UK at Hinkley Point C in somerset; at Flaman-ville in France; and at Olkiluoto in Finland. All involve the European Pressurized reactor technology of EDF that will be used at Hinkley Point. All are running years late and over budget. In the US, the first two nuclear projects under way for the past 30 years are also blowing through cost estimates .

The UK, which opened the world’s first commercial nuclear reactor in 1956, is one of the few western nations committed to renewing its ageing fleet to ensure energy security and meet tough carbon reduction targets. It is seen as a proving ground, by many in the industry, of nuclear power’s ability to restore confidence. However, the country’s under severe criticism over its cost. The government is looking at different funding models but said it still sees nuclear power as vital to the country’s future energy mix. Small reactors, it believes, have the potential to generate much - needed power from the 2030s.

1. What can be learned from the passage about the advanced modular reactors (AMRs)?

A．They don’t work on the same principles as traditional reactors.

B．They haven’t been widely used for business purposes.

C．They are at a critical stage of being manufactured.

【推荐1】It's a little hard to figure out the rules for sure,   but the baby African buffalo(水牛) seems to have the upper hand. The two stand a couple feet apart, staring at each other. Behind them, their mothers look on with the kind of indifference(不关心) of mothers everywhere who see their kids playing a harmless game.

The alarm went off about half an hour ago, the second time tonight. Here, one bell means “elephant”, two, “rhino” (犀牛), and three and four, I really can't remember for what, because when you're awoken by bells in the middle of the night, your first thought won't be “Animal! ”.   But as soon as I realized it was the rhino alarm, I was running for the stairs.

Yet I'm the only one watching the animals stare-down. Either everyone else died of a heart attack when the bells went off, or l was the only one in the entire hotel who didn't turn the alarm switch to off before going to bed.

The Ark,   a hotel shaped like the biblical ark(圣经的方舟) , lies in the highlands of Kenya's Aberdare National Park, about 100 kilometers north of Nairobi. At the Ark's prow(船首) are huge windows overlooking a waterhole. Earlier tonight, I'd watched a pack of wolves, buffalos and elephants. And now, at three or so in the morning, I'm down for rhino bells. The first time, 2. 5 hours ago, it was a single black rhino, which came down, got a drink, and left.

I'd have been sorry for the lost sleep.   I've already arranged with a guide to take me out at sunrise for the so-called “should_never_miss” bird-watching, where we'll get to see 30 species, but really, how many times in your life will you get to wake up and say, “Wow! Rhino!”? Isn't that the definition of a pretty good night? Last week we went from Uganda into Kenya.   Before I left home, 1 thought I'd be happy with ten elephants and five or six giraffes on the whole trip. I didn't dare to dream the rhino.

1. The message that the hotel's bells sent was ___________.

【推荐2】South African singer Larry Joe found in solitary confinement（隔离监禁）the peace of mind he needed to develop his talent. A producer helped him make a CD in a cell-turned-studio.

Joe，31，can see only seven stars outside his window in a prison in Douglas，South Africa for housebreaking. But he has a guitar and a wild hope.

“I want to be a bright star. I want people，when they hear me，to see the darkness much less. ” Joe said.

On December 1，2008，one of South Africa's top musical groups，Freshly Ground，was in Douglas for a concert to mark World AIDS Day.

Joe was also invited to play in the support act. He stunned the audience. “Everyone was totally attracted. I was blown away because I hadn't heard a better voice like that before,”   Aron Turest Swartz，Freshly Ground's founder recalled.

When Joe was 13，his parents moved to Douglas. Being poor，his sister would tell him that she had a headache for bread，but he had nothing to give her. Joe made bad friends，who were always talking about stealing. Later，Joe slipped into crime to help reduce the burden of family. Finally，he was put into prison for housebreaking.

Prison could have broken him: his father died when he was in prison. So did Joe's 18-month-old daughter. Before prison，he'd see her in the hospital，medical tubes everywhere. Joe felt broken when she died. But it marked the time of his rebirth. He stopped pretending there was an excuse for his crime.

On December 13，2010，the album he recorded in prison was timed for release.

He was paroled（假释）for good behavior after two years and 10 months. That afternoon，Joe gave a concert at the prison to celebrate his freedom.

It was time to say goodbye to his seven stars.

【推荐3】Chinese fashion designer Wang Tao released her fall-winter 2019 collection in New York on February 9, the tenth time her brand, Taoray Wang, has been featured at the New York Fashion Week.

Sitting on the front row of the show were U. S. President Donald Trump’s youngest daughter Tiffany Trump with her mother Marla Maples, as well as former Fox News host Kimberly Guilfoyle.

Tiffany Trump, a fan of Taoray Wang, wore a custom made white double-breasted coat by Wang to her father’s inauguration(就职典礼)ceremony in January 2017.

Wang’s latest collection, Eternity, is partly inspired by Tiffany Trump. In this collection, Wang combines the unconventional beauty of the 1970s,represented by famous American model Lauren Hutton and the female look favored by people such as Tiffany Trump.

The two women are from in two different age groups with two different styles but both are confident and brave, said Wang while attending her show in Manhattan. “Beauty is not about time or age. It’s all about attitude.’’

Along with China’s growing economic strength, Chinese fashion has gradually gained worldwide attention, said Wang, adding that only when more and more foreigners wear clothes designed by Chinese people, will it mean a real rise of Chinese fashion on the global stage.

Wang has a diverse background. With a degree in history from East China Normal University in Shanghai,Wang got a second degree in fashion from Japan’s top fashion institute Tokyo Mode Gakut'n, where she received five international awards in design. She was selected by Junko Koshino—a well-kown Japanese designer, to head the studio as the chief men’s designer.

To realize her global career ambitions, Wang then left Japan to go to the UK where she worked as a leading designer. In 2002 she returned to China and led the repositioning of broadcast :bo, making it one of the top 10 Chinese women’s labels. Wang is currently a board member of the Shanghai Ribo Fashion Group.

【推荐2】It turned out there were a lot of things I had yet to learn about life,or at least life on the Princeton campus in the early 1980s.After I spent several energizing weeks as a summer student,surrounded by a few dozen other kids who seemed both accessible and familiar to me,the fall semester officially began, opening the floodgates to the student population at large.I moved my belongings into a new dorm room,a one-room triple in Pyne Hall,and then watched through my third-floor window as several thousand mostly white students poured onto campus,carting stereos and duvet sets and lots of clothes.Some kids arrived in limos(豪华轿车)One girl brought two limos to accommodate all her stuff.

Princeton was extremely white and very male.There was no avoiding the facts . Men on campus outnumbered women almost two to one Black students made up less than 9 percent of my freshman class.It during the orientation program we’d begun to feel some ownership of the space,we were now glaring anomaly(异类)－poppy seeds in a bowl of rice.While Whitney Young had been somewhat diverse,I’d never been part of a predominantly white community before.I’d never stood out in a crowd or a classroom because of the color of my skin.It was jarring and uncomfortable,at least at first,like being dropped into a strange new terrarium,a habitat that hadn’t been built for me.

As with anything,though,you learn to adapt.Some of the adjustment was easy-a relief almost.For one thing,nobody seemed much concerned about crime.Students left their rooms unlocked,their bikes casually kickstanded outside buildings,their gold earrings unattended on the sink in the dorm bathrooms.Their trust in the world seemed infinite,their forward progress in it entirely assured.For me,it was something to get used to. I’d spent years quietly guarding my possessions on the bus ride to and from Whitney Young.Walking home to Euclid Avenue in the evenings,I carried my house key placed between two fingers and pointed outward,in case I needed it to defend myself.

At Princeton,it seemed the only thing I needed to be careful about was my studies.Everything otherwise was designed to accommodate our well-being as students.The dining halls served five different kinds of breakfast.There were enormous spreading oak trees to sit under and open lawns where we could throw Frisbees to relieve our stress.The main library was like an old-world cathedral,with high ceilings and glossy hardwood tables where we could lay out our textbooks and study in silence.We were protected,cocooned,catered to.A lot of kids,I was coming to realize,had never in their lifetimes known anything different.

Attached to all of this was a new vocabulary, one needed to master.What was a precept?What was a reading period?Nobody had explained to me the meaning of”extra-long”bedsheets on the school packing list. which meant that I bought myself too-short bedsheets and would thus spend my freshman year sleeping with my feet resting on the exposed plastic of the dorm mattress.There was an especially distinct learning curve when it came to understanding sports.I’d been raised on the bedrock of football,basketball,and baseball,but it turned out that East Coast prep schoolers did more.Lacrosse was a hing.Field hockey was a thing.Squash,even,was a thing.For a kid from the South Side,it could be a little dizzying.”You row crew?”What does that even mean?

【推荐3】The name of the race comes from the name of an Alaska gold rush town, Iditarod. It means “distant” or “distant place.” It comes from one of the languages of native Alaskans.

More than sixty sled teams begin the race in Anchorage. When the teams reach the outskirts(郊外) of town, they get a taste of Alaska’s wilderness. For about two weeks, they will fight the unbearable cold, wind, snow, and ice to complete the race. The temperature on the trail is often well below zero degrees. The Iditarod trail extends for about a thousand miles. It has many rendezvous points. At these meeting places, the race teams “check in” to let the officials know how they are doing. Some teams get into trouble along the way. Officials will stop them and give them the help they need. For example, officials might stop a team’s progress to give first aid, or to collect an injured or tired dog. These dogs are well cared for and will be reunited with their owners after the race.

The Iditarod trail is an important part of Alaska’s history. A part of the trail was used by some heroic dogs and humans in 1925. In Nome, Alaska, many people were catching the deadly disease Diphtheria. So the whole town was in quarantine, or isolation, in order to stop this disease. The only way to get medicine to Nome was by dogsled. About twenty "mushers, "or dogsled drivers, offered to help. They wanted to save the people of Nome from this terrible disease.

Today the Iditarod race shows honors to this special heroic journey and to all of the journeys on the famous trail. As the race organizers say, the Iditarod is “the last great race on Earth.”

1. Which of the following is TRUE about the Iditarod race?

A．It is held every year in the downtown streets in Anchorage.

B．It usually lasts about two weeks in freezing cold weather.

C．It is held to honor the gold seekers who once lived in Iditarod.

D．Its trail is totally different from the one used by some heroic dogs.

2. In the race, it’s possible for a seriously injured dog ______.

A．to finish the race unnoticed	B．to meet its owner again
C．to work for a new owner	D．to get timely treatment

3. When a town is in quarantine (in Paragraph 3), people in the town ______.

A．can get whatever they want easily	B．have to exchange gold for medicine
C．are not allowed to go out freely	D．will be remembered as heroes

4. The passage is mainly about ______.

A．life in Alaska	B．a dogsled race of Alaska
C．a period of Alaska’s history	D．heroic dogs and people in Alaska
