1 . For today’s increasingly interconnected food supply chains, “efficient” is what it’s supposed to be: Each country specializes in what it’s best, at and puts it on the global market. Producers and processors within countries specialize, too, as a way to minimize costs. As a result, at least in theory, prices stay low, the world gets fed and everyone wins.
However, the coronavirus crisis demonstrates what is wrong with this approach. When barriers prevent food from reaching its markets, or demand suddenly drops — both of which are happening now — the system falls apart.
Specialization of the food system makes it hard to shift into different markets when disruptions arise. Belgium, a leading exporter of potatoes, lost sales not only to local restaurants but also to other countries because of lockdowns（封锁）. At least the Belgians can try to eat the potatoes at home. That strategy won't work for every crop: Ghana, the world’s top cocoa exporter, lost markets when people stalled focusing on buying essential items instead of chocolate.
The loss in export income in Africa more generally could have a huge impact if the pandemic continues, as many countries there rely heavily on imported wheat and rice. The prices of these grains have soared not only because of rising demand for these grains during the crisis, but also because a few countries — including Russia and Vietnam — imposed export restrictions out of fear that sending food abroad would lead to higher prices at home.
Concentrated markets dominated by just a handful of companies heighten food system fragility. For example, just three meatpacking plants process over 95 percent of Canada’s beef and nearly all of its beef exports. Now, those meat processing plants have had to temporarily shut down because of outbreaks of COVID-19 among workers.
Seeing the spoiled products across the world should force all of us to rethink our “efficient” food supplies. We need to rejuvenate（使恢复活力）local and regional food systems to reduce the vulnerabilities that come with being too reliant on imported and corporate-dominated foods. This doesn’t mean cutting off all trade or abolishing all packaged foods, but it does mean building diversity, and increasing opportunities for small and medium-scale enterprises to flourish in shorter, more sustainable food supply chains that are closer to home.
One place to start is for governments to shift their support from the large-scale, specialized and export-oriented food system to building infrastructure for more diverse local food systems. Around the world, small-scale and organic producers have been overwhelmed with the surge in interest from customers who want to buy directly from farmers during the crisis. But these producers often lack the infrastructure to meet that demand. As governments around the world pass stimulus packages to address the crisis, building more diverse and localized food systems should be an obvious inclusion.

2 . World’s loneliest marathon
Many of us know about Russia’s Lake Baikal from our textbooks, or by listening to Chinese singer Li Jian’s hit song, Lake Baikal. But over the past decade, the world’s deepest freshwater lake has been in the spotlight for an extreme sport.
Each March since 2005, about 150 people from around the world sign up for the Baikal Ice Marathon. They come to explore the lake’s breathtaking beauty and challenge themselves in unpredictable conditions.
The 26-mile (41.84-kilometers) journey starts on the lake’s eastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.
Known as the “blue eye of Siberia”, Lake Baikal has exceptionally clear waters. This means its ice is almost perfectly transparent. “Seen from above, a runner on the ice looks as if he or she is jogging through space,” The New York Times noted.
The landscape might be beautiful, but it’s also harsh. Strong winds blast across the lake and frostbite can occur within half an hour. Runners say the cold climate is what draws them. They want to test their limits.
“When you are in such an environment, you don’t have cars around you, you don’t have the noise around. I think these extreme races allow you to be alone with nature,” Alicja Barahona, a 64-year-old runner from the US, told ABC News.
The location offers some strange and unique characteristics for this marathon. The finish line is visible from the start, but the endless white offers no progress markers. The race also ends with little fanfare (喧闹). Tourists crowding the ice are mostly addicted to snapping selfies (自拍) and just ignore the runners.
For some runners, the absence of spectators (观众) makes the race more challenging, because it’s lonely. They must fight with themselves. “You are alone on Baikal. It is your race. You are alone with yourself. All you need to do is to defeat yourself,” Veronique Messina, a French runner, told the Telegraph.

3 . As online technology advanced, web sites, podcasts, and blogs became powerful sources of information that allowed everyone to stay updated on any subject imaginable. Although all of these information sources remain popular, there's a new king of media and it's online video.
There are many reasons why online video has increased suddenly over the past few years. The first is increasing data speeds. It wasn't until recently that people everywhere had fast enough online connections to enjoy high-definition （高清）videos. However, once faster Internet speeds were provided, people quickly fell in love with online videos. The second reason why online videos have become so popular is convenience. Watching videos requires less effort and energy than reading through paragraphs of text after a day of hard work. Videos also seem to provide more satisfaction, as people prefer to connect with people they can hear and see, as against the words of some author whom they know little about.
Advancing digital technology has also helped, as it has made sharing videos easier and more convenient than ever. High-powered smartphones and more affordable video cameras allow anyone to easily record an event or give a few comments about a scorching topic that is on their mind. Meanwhile, sites like YouTube, Vimeo, and Ustream allow users to quickly upload their videos and share them with friends, family, and the general public if they wish.
Last but not least, advertising. Companies have made it easy for people to get rewarded for creating popular videos. Some people with large enough fan bases can even make a very wealthy living by uploading a few videos every week.
The future also looks bright for companies who post online video ads. In fact, new software allows them to watch viewers' emotional reactions to their content through the users' webcams （网络摄像机）.They'll be able to see whether users laugh, cry, or feel bored during videos, so they can adjust their ads. This should prove extremely helpful, as there will be millions of videos competing for viewers' attention.
1. Why do some people prefer watching videos to reading after work?| A．It helps them review the news. |
| B．It helps them get information with relative ease. |
| C．It provides them more information. |

| A．It will enable them to better understand what customers enjoy. |
| B．It will let more viewers see the advertisements they make. |
| C．It will cause viewers to create more popular videos. |
| D．It will make people like their videos. |
| A．Online Video: The New King of Media |
| B．Online Technology is Developing Fast |
| C．Online Video: A New Advertising Trend |
| D．Online Technology is Closely Related to People |
4 . Recently whenever I turned on my computer or my mobile phone, news about the great effect of Hurricane Harvey（哈维飓风）on thousands of people caught my eye. I saw many unfortunate events. However, there was also lots of bright news that showed the goodness of mankind. As a reporter, I reported many human-interest stories when doing my job, That’s why the story about the guys in the bakery（面包店）caught my eye.
When the workers at a Mexican bakery chain in Houston were trapped inside the building for two days, they didn't sit there feeling sorry for themselves. They used their time wisely after flooding caused by Hurricane Harvey. While waiting for the eventual rescue that came on Monday morning, the four workers decided to make as many loaves of bread as possible for people around the neighborhood. They talked to their manager about their plan over the phone and the manager agreed.
The flood water rose in the street outside. They took advantage of their emergency power supply to bake bread. They used more than 4,200 pounds of flour（面粉）to create hundreds of loaves and sheets of sweet bread. Although the water kept rising, they continued baking to help more people. By the time the manager managed to get to them, they had made so much bread that they took the loaves to lots of emergency centers across the city for people affected by the floods.
The store manager, Brian Alvarado, told The Independent, “They've done more than they should have done. And what they had done has lit a light for people. I feel lucky to have them work in the bakery.”
Whenever a disaster occurs, nobody should feelforlorn. Instead, we should stay hopeful and take positive action to save ourselves and help others. Our acts of kindness will make a big difference to the people in the world as well as the world itself.

5 . Some people say global English is no longer just controlled by British or American English,but is running free and developing uniquely local forms.Can you figure out the following terms?
“I like your smile,but unlike you put your shoes on my face.”This is a way of saying“Keep off the grass.”Or“people mountain,people sea”,which means“very crowded”.
These examples are what we call Chinglish.When it comes to Chinglish,if all you know is“good good study,day day up”,you will be considered“out man”.
Nowadays,more Chinglish words have been created,for example,a Chinese idiom is translated as“smilence”,a combination by the English word smile and silence.
Chinglish usually offers a humorous look at misuses of the English language in Chinese street signs,products,and advertising.They are favoured by some English speaking tourists and visitors.Dominic Swire has been living in Beijing for a couple of years.“I think many Chinese people complain about the Chinglish and badly translated English.But you know,sometimes for us foreigners,it’s actually quite charming to see them.I think if the translations of English in China were all perfect,then something would be lost from Chinese culture.”
However,Chinglish will probably become a“cultural relic”in the near future.Beijing has made a comprehensive plan to improve foreign language services and correct Chinglish within five years.“It is very ridiculous to see Chinglish on the signs in some scenic spots.And they are a kind of barrier for communication between Chinese and people from other countries,”a Beijinger said.
Some Chinese university experts side with Chinglish.They argue that English has absorbed elements from other languages such as French and Spanish in its growth,and now it’s Chinese’s turn.
1. What can we call Chinglish?| A．English words which get new Chinese meanings. |
| B．The Chinese words which are difficult to translate. |
| C．The words combining English vocabulary and Chinese grammar. |
| D．The local words preventing foreigners from learning Chinese well. |
| A．Saying nothing but to smile. | B．Smiling without being noticed. |
| C．Laughing at somebody. | D．Knowing little about speech. |
| A．It can show the humour of Chinese. | B．It will attract more foreign tourists. |
| C．It helps him to learn Chinese well. | D．It seems part of Chinese culture. |
| A．Because it has become a unique bridge between Chinese and English. |
| B．Because Chinglish is a chance to enrich Chinese and English. |
| C．Because it improves the understanding between Chinese and foreigners. |
| D．Because Beijing is determined to get rid of Chinglish signs. |
6 . According to a recent study in the Journal of Consumer Research, both the size and consumption habits of our eating companions can influence our food intake. And contrary to existing research that says you should avoid eating with heavier people who order large portions(份), it's the beanpoles with big appetites you really need to avoid.
To test the effect of social influence on eating habits, the researchers conducted two experiments. In the first, 95 undergraduate women were individually invited into a lab to ostensibly(表面上)participate in a study about movie viewership. Before the film began, each woman was asked to help herself to a snack. An actor hired by the researchers grabbed her food first. In her natural state, the actor weighed 105 pounds. But in half the cases she wore a specially designed fat suit which increased her weight to 180 pounds.
Both the fat and thin versions of the actor took a large amount of food. The participants followed suit, taking more food than they normally would have. However, they took significantly more when the actor was thin.
For the second test, in one case the thin actor took two pieces of candy from the snack bowls. In the other case, she took 30 pieces. The results were similar to the first test: the participants followed suit but took significantly more candy when the thin actor took 30 pieces.
The tests show that the social environment is extremely influential when we're making decisions. If this fellow participant is going to eat more, so will I. Call it the “I’ll have what she's having” effect. However, we'll adjust the influence. If an overweight person is having a large portion, I'll hold back a bit because I see the results of his eating habits. But if a thin person eats a lot, I'll follow suit. If he can eat much and keep slim, why can't I?
1. What is the recent study mainly about?| A．Food safety. | B．Movie viewership. |

7 . Returning to a book you’ve read many times can feel like drinks with an old friend. There’s a welcome familiarity - but also sometimes a slight suspicion that time has changed you both, and thus the relationship. But books don’t change, people do. And that’s what makes the act of rereading so rich and transformative.
The beauty of rereading lies in the idea that our bond with the work is based on our present mental register. It’s true, the older I get, the more I feel time has wings. But with reading, it’s all about the present. It’s about the now and what one contributes to the now, because reading is a give and take between author and reader. Each has to pull their own weight.
There are three books I reread annually .The first, which I take to reading every spring is Emest Hemningway’s A Moveable Feast. Published in 1964, it’s his classic memoir of 1920s Paris. The language is almost intoxicating (令人陶醉的)，an aging writer looking back on an ambitious yet simpler time. Another is Annie Dillard’s Holy the Firm, her poetic 1975 ramble (随笔) about everything and nothing. The third book is Julio Cortazar’s Save Twilight: Selected Poems, because poetry. And because Cortazar.
While I tend to buy a lot of books, these three were given to me as gifs, which might add to the meaning I attach to them. But I imagine that, while money is indeed wonderful and necessary, rereading an author’s work is the highest currency a reader can pay them. The best books are the ones that open further as time passes. But remember, it’s you that has to grow and read and reread in order to better understand your friends.

| A．It’s a brief account of a trip. |
| B．It’s about Hemingway’s life as a young man. |
| C．It’s a record of a historic event. |
| D．It’s about Hemingway’s friends in Paris. |
| A．Debt |
| B．Reward. |
| C．Allowance. |

| D．He teaches reading. |
8 . In 2012, James Cameron, creator of Avatar and Titanic, became the first person to reach the Challenger Deep. When he arrived at the deepest spot on Earth at 7 miles below sea level, he spent hours mapping the region and taking photos and samples.
“As human beings, we’re drawn to absolutes—the deepest, the highest, the coldest, the farthest,” he says. “And as a storyteller and curious monkey, I just wanted to see what was there.” The answer is obvious—plastic and more. “Our so-called civilization is using the ocean as its toilet,” Cameron says. “Unless this changes, ocean ecosystems are going to continue their rapid collapse.”
Despite decades of environmental studies, the impact of plastic and other forms of pollution on oceans are not entirely understood. Initial studies appear to indicate that ingesting(摄取) them—either directly or indirectly—could cause disease. Plastics can also release poisonous substances into the water, which could potentially impact animal populations.
But plastic is just one of the problems facing oceans that have yet to be fully understood. “Plastic waste in the ocean is horrifying but is only the most obvious of our many deadly waste streams, which include carbon that’s heating the atmosphere and making the ocean acidic, and the run-off nutrients from all the world’s agriculture, which is causing anoxic(缺氧的) dead zones the size of countries,” Cameron says.
Oceans, like the rest of the world, are impacted by the burning of fossil fuels and the release of greenhouse gases like carbon dioxide—about 30 percent of which is absorbed by the sea. This absorption causes ocean acidification, where the pH level is altered to become more acidic. As a result, it’s harder for some creatures to form shells and skeletons and countless species at the base of the food web can struggle to survive, which, scientists say, has the potential to cause huge disruptions to entire ecosystems. Indeed, ocean acidification is thought to have played an important role in Earth’s worst-ever mass extinction event 252 million years ago.
The effect of climate change on the world’s oceans will likely worsen in coming decades. Last June, scientists announced carbon dioxide levels had reached the highest levels since human records began. The last time carbon dioxide levels were this high was during the Pliocene era, between 3 and 5 million years ago, when global temperatures were about 4 degrees Celsius warmer than they are today. Current climate models suggest that if greenhouse gas emissions continue on their current trend, we may be on course to see 4 degrees of warming by 2100.
As a result, understanding the role oceans have on global systems is becoming more and more important.

9 . It is rightly said one can share any secret with a true friend. He may know your deepest fears and weaknesses and yet will never take advantage of you. However, keeping a friend’s secrets to yourself and not telling the world is what makes the bond grow strong and last forever. You need to develop trust and mutual (互相的) understanding before you start sharing secrets with each other. With friends, secret talks never seem to end and it can get really amusing to know what has been going on in your friend’s mind.
There is a certain time in life especially from the teenage years when one starts having a personal periphery (界限) in life and parents are excluded (排斥) from it. It is because there are certain things that they can’t understand and we can’t discuss with them. That is when friends become the best secret sharers. They are the ones to whom one reveals one’s feelings and best kept secrets.
It is a general belief that only girls share secrets. But boys have their own secrets that they discuss with only closest friends. The secret talks can range (变化) from relationships, talks about fights with parents, secret activities and anything that is not supposed to be known to others! If you think secrets are limited to only teenagers, get your facts right! Secrets can be shared at any age and there is no hard and fast rule that secrets are shared only among youngsters.
Sharing secrets with a friend is not just fun, but it also helps to develop a lasting trust in one another. Sometimes, sharing secrets will tell you more about the person. You will come to know whether your friend is reliable and trustworthy and whether it is worth sharing your secrets with them. You can call it a test of friendship.

| D．It does harm to a strong bond. |
Proudly reading my words, I glanced around the room, only to find my classmates bearing big smiles on their faces and tears in their eyes. Confused, I glanced toward my stone-faced teacher. Having no choice, I slowly raised the report I had slaved over, hoping to hide myself. “What could be causing everyone to act this way?”
Quickly, I flashed back to the day Miss Lancelot gave me the task. This was the first real task I received in my new school. It seemed simple: go on the Internet and find information about a man named George Washington. Since my idea of history came from an ancient teacher in my home country, I had never heard of that name before. As I searched the name of this fellow, it became evident that there were two people bearing the same name who looked completely different! One invented hundreds of uses for peanuts, while the other led some sort of army across America. I stared at the screen, wondering which one my teacher meant. I called my grandfather for a golden piece of advice; flip (掷) a coin. Heads—the commander, and tails—the peanuts guy. Ah! Tails, my report would be about the great man who invented peanut butter, George Washington Carver.
Weeks later, standing before this unfriendly mass, I was totally lost. Oh well, I lowered the paper and sat down at my desk, burning to find out what I had done wrong. As a classmate began his report, it all became clear, “My report is on George Washington, the man who started the American Revolution.” The whole world became quite! How could I know that she meant that George Washington?
Obviously, my grade was awful. Heartbroken but fearless, I decided to turn this around. I talked to Miss Lancelot, but she insisted: No re-dos; no new grade. I felt that the punishment was not justified, and I believed I deserved a second chance. Consequently, I threw myself heartily into my work for the rest of the school year. Ten months later, that chance unfolded as I found myself sitting in the headmaster’s office with my grandfather, now having an entirely different conversation. I smiled and flashed back to the embarrassing moment at the beginning of the year as the headmaster informed me of my option to skip the sixth grade. Justice is sweet!
