1 . 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.

2 . Albert Einstein’s 1915 masterpiece “The Foundation of the General Theory of Relativity” is the first and still the best introduction to the subject, and I recommend it as such to students. But it probably wouldn’t be publishable in a scientific journal today.
Why not? After all, it would pass with flying colours the tests of correctness and significance. And while popular belief holds that the paper was incomprehensible to its first readers, in fact many papers in theoretical physics are much more difficult.
As the physicist Richard Feynman wrote, “There was a time when the newspapers said that only 12 men understood the theory of relativity. I do believe there might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper a lot understood the theory of relativity in some way or other, certainly more than 12.”
No, the problem is its style. It starts with a leisurely philosophical discussion of space and time and then continues with an exposition of known mathematics. Those two sections, which would be considered extraneous today, take up half the paper. Worse, there are zero citations of previous scientists’ work, nor are there any graphics. Those features might make a paper not even get past the first editors.
A similar process of professionalization has transformed other parts of the scientific landscape. Requests for research time at major observatories or national laboratories are more rigidly structured. And anything involving work with human subjects, or putting instruments in space, involves piles of paperwork.
We see it also in the Regeneron Science Talent Search, the Nobel Prize of high school science competitions. In the early decades of its 78-year history, the winning projects were usually the sort of clever but naive, amateurish efforts one might expect of talented beginners working on their own. Today, polished work coming out of internships(实习) at established laboratories is the norm.
These professionalizing tendencies are a natural consequence of the explosive growth of modern science. Standardization and system make it easier to manage the rapid flow of papers, applications and people. But there are serious downsides. A lot of unproductive effort goes into jumping through bureaucratic hoops(繁文缛节), and outsiders face entry barriers at every turn.
Of course, Einstein would have found his way to meeting modern standards and publishing his results. Its scientific core wouldn’t have changed, but the paper might not be the same taste to read.

3 . More and more travellers in China nowadays prefer homestays rather than traditional hotels, as they seek private living experiences. The house-sharing model was first introduced by the website Couchsurfing.com in 2003. It is still the largest website for travellers to find accommodation (住宿) without much money to spend.
Encouraged by her great experience of homestays in France, Maggita, 30, considered short-term hire as her first choice in her future trips. She later went back to her hometown Shanghai and ran a "shared accommodation" business.
The short-term hire idea has been a win-win business model. For travellers, they can rent a special room at a reasonable price and also enjoy a firsthand experience of the local culture, compared with traditional hotels. For owners, they can gain much with daily rental. Now Maggita has quit her last job in an IT company and become a host of some 20 homestays, which enables her to earn a monthly income of around 40,000 — 50,000 yuan.
In recent years, China has seen many homestay booking websites such as Xiaozhu and Tujia. Chen Chi, the founder and CEO of Xiaozhu, said the model is to share rooms or apartments that are not in use with people who need them. Instead of the traditional view that Chinese people feel uncomfortable living with strangers, Chen found that a large number of travellers got along well with house owners.
However, experts have pointed out a series of problems brought about by the fashion. Lacking supervision (监管) to those accommodation sharing websites, the service quality and accommodation safety cannot be guaranteed (保障).Experts suggest that the online websites should closely work together with communities and local police stations to improve the services.

| C．Well-accepted. | D．Uncomfortable. |
| A．Homestays need to be improved. |
| B．Some experts don't support homestays. |

4 . Killer whales, or orcas, are known for their severe attacks on sea animals but they have never posed a threat to humans. However, since late July, the normally social animals have been intentionally attacking sailboats off the coasts of Spain and Portugal.
The strange behavior first surfaced on July 29, 2020, when a 46-foot boat was repeatedly attacked for almost an hour by nine orcas, causing the boat to rotate(旋转) 180 degrees and having its engine switched off. Since then, over 30 more similar incidents have been reported. On September 23, 2020, Spain's government banned boats of less than 50 feet in length from sailing in the 60-mile stretch of the Atlantic coastline between Ferrol and the Estaca de Bares Cape, where the attacks have been occurring.
Researchers across the world are trying to explain the orcas' behavior. Some believe it could be a result of the overfishing of the bluefish tuna - the orcas' primary food source -which has left the area's killer whales starving and unable to feed their babies. "I saw them look at boats carrying fish. I think they know humans are somehow related to food shortages, "says Ken Balcomb, senior scientist at the Center for Whale Research in Washington, USA. The environmentalists believe the sudden increase in boat traffic and fishing activities, after months of absence due to restrictions on human activity last spring, could also be contributing to the agitation.
However, Alfredo López, a biology professor in Galicia, Spain, thinks the attacks are defensive measures the orcas adopted to protect themselves against boat injuries. The researcher came to this conclusion after looking at the of the videos of a few incidents and noticing that two of the young killer whales involved had serious injuries. Hopefully, the experts will be able to find a way to restore the harmony between the animals and the humans soon.

5 . “Birds” and “airports” are two words that, paired together，don’t normally paint the most harmonious picture. So it really raises some eyebrows when China announces plans to build an airport that is for birds.
Described as the world’s first-ever bird airport, the proposed Lingang Bird Sanctuary(保护区）in the northern coastal city of Tianjin is, of course,not an actual airport. Rather，it's a wetland preserve specifically designed to accommodate hundreds-even thousands-of daily takeoffs and landings by birds traveling along the East Asian-Australian Flyway. Over 50 species of migratory (迁徙的）water birds，some endangered, will stop and feed at the protected sanctuary before continuing their long journey along the flyway.
Located on a former landfill site，the 150-acre airport is also open to human travelers.(Half a million visitors are expected annually.) However，instead of duty-free shopping，the main attraction for non-egg-laying creatures at Tianjin’s newest airport will be a green-roofed education and research center, a series of raised “observation platforms” and a network of scenic walking and cycling paths totaling over 4 miles.
“The proposed Bird Airport will be a globally significant sanctuary for endangered migratory bird species, while providing new green lungs for the city of Tianjin.” Adrian McGregor of an Australian landscape architecture firm explained of the design. Frequently blanketed in smog so thick that it has shut down real airports, Tianjin is a city---China’s fourth most populous----that would certainly benefit from a new pair of healthy green lungs•

6 . As people get older, the types of friends they have tend to change. As young adults, humans have a lot of friends. With age, they often prefer to spend their time with just a few close, positive individuals. Researchers long believed that this change was unique to humans, but a new study finds that chimps also have similar tendencies.
One explanation for the humans to get picky about social connections has to do with awareness of our limited life span. “People monitor how much time we have left in our life and choose emotionally-fulfilling relationships in old age,” says one of the study's lead authors Alexandra G. Rosati, a psychologist at the University of Michigan. As people age, they don’t want to be surrounded by a large group of negative friends, but would prefer to be near a handful of optimistic individuals.
Rosati and her colleagues were curious whether chimps would show similar features even though they don’t seem to be aware of their upcoming death. Researchers used 78, 000 hours of observations made over 20 years from the Kibale Chimpanzee Project in Uganda. The data looked at the social interactions of 21 male chimps between 15 and 58 years old. The researchers only studied male chimps because they show stronger social bonds and have more social interactions than female chimps.
Researchers found that wild chimpanzees share a similar pattern. “They interact with others in more positive ways as they get older. Younger adults, in contrast, show more aggression and were more likely to form one-sided relationships where their partner did not reciprocate. ”says Rosati. For example, the older chimpanzees would sit close to their long-time companions and groom (给……梳毛) each other, while younger chimps had more one-sided relationships where they would groom a friend, but the action wasn't returned. The study was published in the journal Science.
“This aging pattern may be the result of shared changes in our abilities to manage our emotions with age,” Rosati says. “This shared pattern between chimpanzees and humans could represent an adaptive response where older adults focus on important social relationships that provide benefits and avoid interactions that have negative consequences as they lose competitive fighting ability.”

7 . When you think of the Himalayas, you may picture tall, rocky, snow-covered peaks. But that’s not true.
The subnival (亚冰雪的) region is the zone between the treeline and the snowline. It is 5 to 5 times as large as the areas of glaciers and permanent snow, which means studying it is vital to understanding the Himalayas as a whole.
The treeline is the edge of an ecosystem where trees are able to grow, and beyond the treeline environmental conditions become too tough to allow tree growth. Meanwhile, snowlines are the boundaries on mountains that separate areas with permanent snow (where snow is present for the majority of the year) from areas with seasonal or no snow.
Researchers used satellite data from 1993 to 2018 to measure plant cover between 4,150 meters and 6,000 meters above sea level. The scientists discovered that the greatest increase in plant cover was between an altitude of 5,000 meters and 5,500 meters. Subnival plants mostly include small shrubs and grasses.
Even areas once completely occupied by glaciers now hold rocks covered with mosses, lichen, and sometimes even flowers. In addition, the snowline seems to be retreating, while the treeline is expanding. This shows that the region is becoming warmer, causing more melting of snow and allowing vegetation to move up in height.
In the past 40 years, 25% of all Himalayan ice has been lost due to global warming. Himalayan glaciers are reducing by about 0.5 meters each year. The rate of glacier melting has doubled in this decade. The melting of glaciers increases water in the region, making it wetter. Receding snow also forces the snowline to move up, providing a greater amount of area for the warm and moist conditions, which are perfect for vegetation growth.
As of now, we do not know whether vegetation will accelerate or slow down the rate of glacier melting.
1. How does the writer develop the third paragraph?| A．By explaining concepts. | B．By providing some examples. |

| A．The climate of the Himalayas is changing. | B．Icebergs in the Himalayas have disappeared. |
| C．Plants are diverse in the Himalayas. | D．Plant life spreads in the Himalayas. |
8 . An Italian company has told staff to stop sending any internal (内部) emails for a week in an effort to reduce stress levels.
Home textiles company Gabel, based in the northern Como region, appointed an expert to interview its employees about what their main concerns were at work, the local La Provincia di Como website reports. Many said that managing the huge volume of internal emails was a burden during the working day. That pushed the company’s management to propose a solution, which — somewhat ironically — was sent to all staff in an email.
“Together we will begin the following experiment, which will take us back in time to when people talked more,” managing director Emilio Colombo wrote, declaring an “email-free” week until 13 November. “We invite you not to use email for internal communications (between colleagues at the same location), in favor of a more direct and immediate contact.”
The company’s president, Michele Moltrasio, tells the BBC it hasn’t been easy to stop such an “ingrained” practice, temporarily, but that employees have welcomed the challenge. “They are rediscovering the pleasure of meeting and talking rather than writing,” he says. And that includes Mr. Moltrasio, who is avoiding emails along with everyone else. “Even if from next week we all go back to using email, these days of experimentation are very worthwhile, to understand and rethink the methods and pace of working,” he says.
Several recent studies have found that a high volume of emails raises stress levels at work. In 2013, researchers said that a full inbox led to peaks in people’s blood pressure and heart rate. And last year, a study at the University of British Columbia found that limiting email use during the day lowered people’s stress levels “significantly.”
1. What did an Italian company do to reduce its employees’ pressure at work?| A．Ask its employees not to send emails anymore. |

| B．Employees don’t communicate with each other so directly as they did in the past. |
| C．It is quite easy for employees to stop using emails. |
| D．Employees’ working stress is due to the large number of emails they deal with every day. |
| A．Negative. | B．Supportive. | C．Doubtful. | D．Reserved. |
9 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.
Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.
1. The text mainly discusses the relationship between ________.| A．heart problems and air quality |

10 . A group of second-year college students have discovered hidden writing on a page from a book from the 1500s, using a special camera system they built.
Surprisingly, finding hidden writing on very old documents isn’t all that unusual. In fact, there’s even a special name for documents like this: a palimpsest (再生羊皮纸卷).
Long ago, writing was done on parchment — thin, dried animal skins specially prepared for writing. But parchment wasn’t easy to make and wasn’t cheap. So it became common to erase the old writing off a parchment and then reuse it for another piece of writing. That’s what creates a palimpsest.
The writing erased off the parchment can’t be seen directly, but scientists have learned ways to use special lighting to reveal the original writing. But it’s unusual for young college students to discover palimpsests.
Last year, first-year students at the Rochester Institute of Technology took part in a class that brought together many students to take on a project as a group. The project was to build a special camera system that could take pictures using different kinds of light.
Over the summer, the students working on the imaging camera managed to finish it. When they were done, they borrowed several old parchments from the collection at the school’s Cary Graphic Arts Collection. When they put one of the pages under their camera system with UV light, the hidden writing suddenly appeared. Under the UV light, handwriting in French could easily be seen behind the fancy writing and decorations normally visible on the page.
Zoe, a student involved in the project, said, “This was amazing because this document has been in the Cary Collection for almost 10 years and no one noticed it.” The students are even more excited because even though the parchment is no longer part of a book, they know where 29 other pages from the same book are. The students, who are now working with others to locate the other parchments, hope these, too, will have hidden writing and that they can figure out what it means.
