1 . Coca-Cola is to test a paper bottle as part of a longer-term goal to get rid of plastic from its packaging entirely. The prototype (样本) is made by a Danish company from an extra-strong paper shell that still contains a thin plastic liner (衬垫). But the goal is to create a 100% recyclable, plastic free botte capable of preventing gas escaping from carbonated (碳酸) drinks. The barrier must also ensure no fibers get into the liquid.
That may have a risk of changing the taste of the drink — or potentially can't meet the requirements of health and safety checks. But industry giants (巨头) are backing the plan. Coca-Cola, for example, has set a goal of producing zero waste by 2030. Coca-Cola was ranked the world's number one plastic polluter by charity group Break Free From Plastic last year, closely followed by other drink-producers Pepsi and Nestle.
The Paper Bottle Company, or Paboco, is the Danish firm behind the development of the paper-based container. Part of the challenge has been to create a structure capable of standing the forces exerted by carbonated drinks — such as cola and beer — which are bottled under pressure. On top of that, the paper needs to be mouldable to create distinct bottle shapes and sizes for different brands and take ink for printing their labels.
After more than seven years of lab work, the firm is now ready to host a trial in Hungary this summer of Coca-Cola's fruit drink Adez. Initially, this will involve 2,000 bottles distributed via a local retail chain.
But it is also working with others. Absolut, the vodka maker, is due to test 2,000 paper bottles of its own in the UK and Sweden of its pre-mixed, carbonated raspberry drink. And beer company Carlsberg is also building prototypes of a paper beer bottle.
Michael Michelsen, the firm's commercial manager, says the bottles are formed out of a single piece of paper-fiber-based material to give them strength.

2 . Scientists are urging that deep sea metal mining should be stopped temporarily. They warn in a report that it can cause severe and damaging effects on Pacific Ocean areas.
The recently-released report examined more than 250 published studies on deep Sea mining. The research was examined by the Deep Sea Mining Campaign——a collection of not-for profit organizations. The report centers on mining activities related to small metallic particles(颗粒; 微粒), called nodules, found on the seabed. The material can contain different metals. Increasing demand for these metals has led to a rise in deep-sea mining operations. The metals are commonly used in battery manufacturing(制造) and other technology products.
However, the scientists warn that mining for these nodules will cause irreversible（无法复原的）damage to an ocean already under pressure. The operations will affect areas across the South Pacific, including the nations of Kiribati, the Cook Islands, Nauru, Tonga and Papua New Guinea.
The report notes that a moratorium is the only responsible way to move forward until certain conditions surrounding deep-sea mining can be met. The scientists are calling for additional study to fully understand the environmental, social and economic risks.
Andrew Chin is the report’s lead researcher. He says in a statement that nodule mining will likely result in the loss of sea life and cause damage to deep seabeds for thousands of years. He adds that the operations can put people at risk who depend on the ocean and its continued health.
A company planning to be one of the first to carry out mining operations in the area is Canada’s Deep Green, which aims to begin by 2024. It seeks to mine metallic nodules to be used in power systems for electric vehicles. Deep Green Chief Executive Officer Gerard Barron defended the company’s plans in reaction to the report. He said deep-sea mining offered the best replacement for surface mining, which has a long history of pollution and destroying forests and wildlife.

3 . Chinese Dragon Head-raising Festival is a traditional Chinese festival held on the second day of the second month of the Chinese calendar. It marks the start of spring and farming. Ancient people believed that after this day, rainfall increases because the rain-bringing Dragon King has woken up from his winter sleep. In ancient times, farming highly depended on the weather. Proper rainfall and plenty of sunlight were necessary for a good harvest at the end of the year. The Chinese dragon, besides a symbol of good luck and great power, is also the god managing weather and water. So Dragon Head-raising Day is about honoring the Chinese dragon and praying for good weather in spring.
The festival celebrates ancient agrarian(农耕的) Chinese culture, and while some of traditional ways to celebrate it are no longer practiced, others persist.
The most famous tradition is getting a haircut. A saying warns that cutting your hair in the first month will cause your uncle to die. Although today few pay attention to it, it was once a tradition for people to line up outside barber shops this day after they avoided haircuts for the preceding(前面的)month.
Today Chinese Dragon Head-raising Day is celebrated in many different ways, most of which are still similar to those practiced in the ancient times, including eating spring pancakes and noodles. People eat tofu balls in East China’s Fujian Province during the festival while fried beans are the traditional festival food for people in parts of Shandong Province. Food eaten on this day also gets a lucky name. For example, noodles are “dragon’s beard” and dumplings are “dragon’s ears”.

4 . We all need waler to survive, but the general recommendation has been to drink more and more, with many guidelines now advising a minimum of eight glasses a day. Is there any evidence showing that this makes sense? The short answer is no. Studies looking at water intakes over 10 years in the elderly fail to show any benefits of extra water on kidney function or lifespan.
Clever marketing from bottled water companies has not only convinced us that we need to drink more water, but also that expensive bottled mineral water is somehow better for us. We now drink more bottled water than ever before, with the global industry growing rapidly at 10 percent a year. By 2025, the global market is estimated to be worth ＄215 billion. But research shows that tap water nowadays is perfectly safe, and with added fluoride （氨化物）, it is also good for our teeth. There have been studies showing that tap water contains traces of common pharmaceutical（制药的）drugs, but they have also found the same levels when testing bottled water. Although water in many areas contains chemicals, the levels are too small to make a noticeable difference to our health.
Bottled water has devastating environmental costs, which is self﹣evident as there are already abundant reports on pollution caused by plastic bottles, and no proven health benefits. And, does it taste better?Probably not. On the contrary, there are even blind tastings showing that tap water scores higher than most mineral water.
So, still hesitate when presented with both bottled water and tap water?Probably you should not now. My advice is to stick with tap water: you will be reducing the global environmental cost of half a trillion plastic bottles piling up each year and taking a stand against the power of marketing.

5 . Think of Japan in the spring and the image that comes to mind is likely the country’s famous cherry blossoms, also known as “Sakura” — white and pink flowers, blooming across cities and mountains.
The flowers, which experience a “peak bloom” that only lasts a few days, have been loved in Japan for more than a thousand years. Crowds celebrate with viewing parties, flocking to the most popular locations to take photos and have picnics underneath the branches.
But this year, cherry blossom season has come and gone in the blink of an eye, in one of the earliest blooms on record. Scientists warn it’s a symptom of the larger climate crisis threatening ecosystems everywhere.
Yasuyuki Aono, a researcher at Osaka Prefecture University, has gathered records from Kyoto back to 812 AD from historical documents and diaries. In the central city of Kyoto, cherry blossoms peaked on March 26, the earliest in more than 1,200 years, Aono said. And in the capital Tokyo, cherry blossoms reached full bloom on March 22, the second-earliest date on record.
The peak bloom dates shift every year, depending on numerous factors including weather and rainfall, but have shown a general trend of moving earlier and earlier. In Kyoto, the peak date stayed around mid-April for centuries, but began moving into early April during the 1800s. The date has only dipped into late March a handful of times in recorded history.
“Sakura blooms are very temperature sensitive,” said Aono. “Flowering and full bloom could be earlier or later depending on the temperature alone,” he said. “The temperature was low in the 1820s, but it has risen by about 3.5 degrees Celsius to this day.”
This year’s seasons in particular influenced the blossom dates, he added. The winter was very cold, but the spring came fast and unusually warm.

6 . Bangladesh's floating gardens, built to grow food during flood seasons, could offer a continuous solution for parts of the world which are likely to suffer from flooding because of climate change, a new study has found.
Bangladesh's floating gardens began hundreds of years ago. The gardens are made from native plants that float in the rivers and operate almost like rafts (筏), rising and filling with the waters. Historically, they were used to continue growing food during rainy seasons when rivers were filled with water.
The farmers layer the plants about three feet deep, creating a version of raised-bed gardens that float in the water. Then, they plant vegetables inside those rafts. As the raft-plants rot away, they release nutrients, which help feed the vegetable plants.
But as climate change affected the volume of water in those rivers, the researchers wanted to understand whether Bangladesh's floating gardens could be a continuous farming practice. They interviewed farming families and found strong evidence that floating gardens provide stability, both in the amount of food available to feed rural populations and in a farming family's income.
They found that farmers typically use hybrid (杂交) seeds, which must be repurchased each year, to grow a diverse range of vegetables in the floating gardens. The gardens are also sensitive to pests, so farmers end up spending some money on both pesticides and fertilizers. But even with those expenses, they found, benefits outweighed costs. One farmer told the research team that he earns up to four times as much money from the gardens as from traditional rice fields.
However, before gaining profits, farmers often take out high-interest loans (贷款) to cover the investment costs of filling the beds and stocking them with plants. Luckily; there are also lower-interest loans from responsible government or non-governmental organizations, which could ease that burden.
1. How do vegetable plants grow according to the text?| A．By absorbing nutrition from raft-plants. | B．By taking shelter from climate change. |
| C．By living together with hybrid seeds. | D．By moving up and down with raised beds. |
| A．“Our life becomes tough when rivers flood.” | B．“Fewer vegetables are planted when water rises.” |
| C．“We harvest much more food during rainy seasons.” | D．“Climate change has little influence on our income.” |
| A．Affected. | B．Brought. | C．Beat. | D．Equaled. |
| A．A solution to climate problem has been found. | B．The gardens are built with rotted native plants. |
| C．Farmers earn more from traditional rice fields. | D．Low-interest loans lighten the stress of farmers. |
7 . Everyone has a phone in their pocket nowadays, but how often do we really use them for their original purpose—to make a call? Telephone culture is disappearing. What brought us to this moment, and what are its effects?
“No one picks up the phone anymore,” wrote Alex C. Madrigal on The Atlantic. “Telephone culture is gone.”
The change is of course due to more communication choices: Texting with photos, videos, emojis, reaction gifs, links and even voice messages can be a more attractive choice.
Texting is light and fun, not nearly as demanding of your attention as a phone call. It can also be done with some people at the same time. Social media, email and video calls have also eaten away at traditional phone calls.
In recent years, another reason has caused people to ignore phone calls completely: robocalls. Robocalls are automate messages from organizations verifying your phone number or telemarketers trying to sell something. Americans received 22.8 billion robocalls halfway through 2020, equaling an annual rate of 45.6 billion, slightly below 2018 numbers, according to YouMail, a robocall protection service and blocking app.
As telephone culture disappears, what is the loss of a traditional family phone doing to the family unit? Early landline phones join family members together, whereas mobile phones separate them.
“The shared family phone served as an anchor (支柱) for home,” said Luke Fernandez, a Weber State University computer-science professor and co-author of Bored, Lonely, Angry, Stupid: Feelings About Technology, From the Telegraph to Twitter. “With smartphones we have gained mobility and privacy. But the value of the home has been diminished, which has its ability to guide and monitor family behavior and perhaps connect families more closely,” Fernandez said.
Of course, as technology progresses, lives always change for better or for worse. With the loss of telephone culture, families will need to find other ways to unite.
1. What is the main idea of the passage?| A．To point out the disadvantages of the traditional phone call. |
| B．To call for the traditional phone to advance with the times. |
| C．To encourage people to make more phone calls and be closer to family. |
| D．To introduce the causes and effects of the disappearing telephone culture. |
| A．changed | B．continued | C．strengthened | D．decreased |
| A．The telephone culture disappeared just because of too many robocalls. |
| B．Some communication choices are more attractive than the traditional phone calls. |
| C．Early landline phones are inconvenient and they separate family members. |
| D．Texting with some people at the same time takes up our attention too much. |
| A．Indifferent. | B．Objective. | C．Pessimistic. | D．Skeptical. |
8 . 2020 was a really tough year. It affected our lives in many ways and made other serious issues even more difficult to address. There was also social and political unrest in the United States and other places around the world.
All of this added up to some big, stressful year called 2020. In fact, 2020 is a song filled with low, depressing notes.
In English, “low notes” are unpleasant things that happen during an event, any event. So if something ends on a low note, it ends in an unpleasant way. For example, once I took a fun vacation. But it ended on a low note. On the last day, all my money was stolen. Then my flight home was delayed. So, I had to sleep in an airport for two days!
However, we also have another phrase-- a “high note”! In English, a “high note” is something pleasant or gratifying.
So, to end something on a high note is to end it with something pleasant. It can also mean to end something at the best possible point -- for example, at the point when something is most successful.
Anything can be a high note, if you choose it to be. For example, 2020 was a disaster. But for me it ended on a high note. One cold night in late December, I saw on owl in a tree near my house. I love owls but had never seen one so close before! That was a high note for me.
Hopefully, all of us were able to end 2020 on a high note.
1. Which of the following does NOT show the writer’s attitude towards the year of 2020?| A．It’s a year that is filled with low notes. |
| B．It’s a year that ends on a high note. |
| C．It’s a year full of easy issues. |
| D．It’s a year full of unforgettable memories. |
| A．Humorous. | B．Enjoyable. | C．Permanent. | D．Concerned. |
| A．Because it ended on a high note. |
| B．Because it is a song with something pleasant. |
| C．Because the author loves owls that have high notes. |
| D．Because the author love owls and saw one so close. |
| A．The usages of “high notes” and “low notes”. |
| B．Examples about “high and low notes”. |
| C．The change of “low notes” and “high notes”. |
| D．Some serious issues about “high and low notes”. |
9 . Now, Amazon has opened a brick﹣and﹣mortar bookstore in downtown Bethesda, and I am not thrilled. One reason is that there is no cafe area. But the biggest reason I am profoundly disappointed is that the new Amazon store does not accept cash. I refuse to use a credit card to pay for small purchases, such as books. I prefer to use cash.
Much has been written about the "unbanked" people who are too poor to afford a credit card or a debit card（借记卡）and who don't have a smartphone. No﹣cash policies are discriminatory against people of low income. In Massachusetts, it is illegal for retail establishments to discriminate against cash﹣paying customers. Several lawmakers in the district are thinking of adopting similar laws.
I am not a person of low income. I do have a credit card, and I occasionally use it. But it is my choice, for lifestyle and money management reasons, to use my credit card only for large purchases. I have decided not to own or use a smartphone, which means that I cannot use apps to make purchases.
For all their convenience, credit cards do come with problems. There are privacy concerns, because credit card purchases can be tracked. There are risks that those using credit cards may become victims of identity theft. And a cashless economy is dependent on functioning computers and uninterrupted power sources. Computers can be hacked, and power outages occur. In these circumstances, a cashless economy simply won't function.
My decision not to patronize stores that discriminate against cash﹣paying customers means that the only bookstore in downtown Bethesda will not be getting my business. In refusing to patronize such businesses, I am standing up for the "unbanked" who can't afford credit cards or smartphones and also for people like me who simply choose to use cash.
1. Why is the author disappointed at the new bookstore mainly？| A．Because there is no cafe area. |
| B．Because there are only e﹣books. |
| C．Because it rejects cash payment. |
| D．Because it doesn't accept credit cards. |
| A．The drawbacks of no﹣cash policy. |
| B．The credit risks of a cashless economy. |
| C．The convenience of credit card payment. |
| D．The privacy concerns of online shopping. |
| A．Sponsor. | B．Shop in. | C．Purchase. | D．Flee from. |
| A．Angry. | B．Worried. | C．Optimistic. | D．Enthusiastic. |
10 . In the world of Chinese archaeology (考古学), a sign of a dig's importance is the sight of Zhou Mingsheng at work. A field technician who has worked at archaeological sites all around China. Master Zhou is credited with the gentlest touch in his profession. Born into a farming family, he is a “national-level craftsman” with a talent for using simple tools to get relics (遗物) that would crumble in other hands, says his current boss, Wang Xu, director of an archaeological site at Shuanghuaishu, a Neolithic (新石器时代的) settlement near the Yellow River in the central province of Henan.
It is not beauty that attracts visitors to Shuanghuaishu. At 5, 300 years old, the settlement is the work of a culture too simple to have left behind many buried treasures. The single most precious find, to date, is a finger-length sculpture of a silkworm. Nor is the setting lovely: an area surrounded by deafening insects, between a highway and two power stations. Rather, the site's importance is historical. For since the birth of Chinese archaeology in the 1920s, it has been inseparable from claims that China has the oldest unbroken civilisation on Earth.
Leading archaeologists say that the site has the right combination of location, age and distinctive cultural elements to be the capital of an early Chinese kingdom. That would make it a bridge between China's written history and the era of the Yellow Emperor, who is said to rule over these central plains almost 5,000 years ago, though many foreign scholars doubt his existence. Chinese media call the site proof of China's 5,000 years of history.
Foreigners complain about a lack of written records, Mr Wang notes. Perhaps they are missing symbols that will one day be understood, for instance in patterned pottery. Outsiders "can't keep using Western standards to apply to Chinese ruins," he argues.
1. What does the underlined word “crumble” in paragraph 1 mean?| A．Result. | B．Break. | C．Wait. | D．Shine. |
