1 . The Chinese manned submersible(潜水器) Fendouzhe, over 96.5 percent of whose core components have been independently developed by China, reached one of the deepest spots on the planet, a dizzying and dark depth of 10,909 meters.
Extreme water pressure is the first challenge that requires dealing with during the exploration. At 10,000 meters down in the ocean, the submersible has to stand about 1,100 atmospheres of pressure, equal to 2,000 elephants stepping on a person’s back. As the solid “armour (盔甲)”，the manned cabin is a safety guarantee for humans to reach down to 10,000 meters deep in the ocean. To overcome the technical bottleneck, the Chinese researchers developed a new material-Ti62A, successfully solving problems of the strength and toughness of the manned cabin.
To avoid risks of crashes in the dark deep sea with complex terrain(地形)，Fendouzhe requires its control system, a smart “brain” to give the exact instructions. Researchers designed a neural network algorithm(神经网络算法), which enables Fendouzhe to travel automatically according to the seabed terrain and locate fixed points. Its control system has reached the international frontier level.
The submersible is equipped with two flexible and strong “arms”. Each 7-joint arm with 6 degrees - of - freedom control and a weight-carrying ability of more than 60 kilograms can cover the sampling basket and its front areas. With the arms, Fendouzhe collected samples of ocean rocks, deep-sea living things and seabed sediments(沉淀物).
The ocean, especially the deep sea, is widely regarded as Earth's final frontier. Deep down in the ocean are unusual creatures, strange environments and impressive geological wonders, yet humanity knows less about the ocean floor than about the far side of the moon. These samples and data collected from the deep ocean can be used for geological and biological research, as well as study the human impact on the planet.

2 . The 2020 Nobel Prize in literature has been awarded to former U.S. Poet Laureate（桂冠诗人）Louise Gluck. The prize committee cited “her unique poetic voice that with plain beauty makes individual existence universal”. Gluck is the first American woman to win the award since Toni Morrison in 1993. Gluck, 77, joins a list of literary giants and previous Nobelists who include, in this century, Canadian short-story master Alice Munro, Chinese magical-realist Mo Yan, etc.
Gluck’s work includes 12 collections of poetry and a few volumes of essays on literary writing. “All are characterized by a striving for clarity（清晰）. Childhood and family life, the close relationship with parents and siblings, is a theme that has remained central to her,” Anders Olsson, the chairman of the Nobel Committee for Literature, said. “She seeks the universal, and in this she takes inspiration from myths and classical motifs,” Olsson added, citing her 2006 collection Averno, which the committee described as “masterly” for its “visionary interpretation of the myth of Persephone’s (珀尔塞福涅) fall into hell in the captivity (囚禁) of Hades(哈得斯), the god of death”.
Being a professor at Yale and a resident of Cambridge, Gluck also served as U.S. Poet Laureate from 2003 to 2004 and is no stranger to awards. She won the Pulitzer Prize in 1993 for her collection of poems titled The Wild Iris, in which “she describes the incredible return of life after winter in the poem Snowdrops,” the Nobel literature committee said Thursday. She also won the 2014 National Book Award for the poem Faithful and Virtuous Night. In 2016, President Obama awarded the National Humanities Medal to Gluck in a White House ceremony.
The publicity-shy Gluck did not immediately issue any comment about the latest honor for her body of work, which spans more than half a century. In a 2012 interview, she acknowledged that prizes can make “existence in the world easier” but did not amount to the immortality(不朽) of a true artist.

3 . Like a tired marriage, the relationship between libraries and publishers has long been dull. E-books, however, are causing heartache. Libraries know they need digital wares, but many publishers are too cautious about piracy（盗版） and lost sales to co-operate. Among the big six, only Random House and Harper Collins license e-books with most libraries.
Publishers are wise to be nervous. Owners of e-readers（电子阅读器） are exactly the customers they need: book-lovers with money. If these people switch to borrowing e-books instead of buying them, what then? Electronic borrowing is awfully convenient. Unlike printed books, which must be checked out and returned to a physical library miles from where you live, book files can be downloaded at home. The files disappear from the device when they are due.
E-lending is not simple, however. There are lots of different and often incompatible（不兼容的）e-book formats devices and licenses. Most libraries use a company called OverDrive, which secures rights from publishers and provides e-books and audio files in every format. Yet publishers and libraries are worried by OverDrive’s global market dominance the company can control fees and conditions. Publishers were annoyed when OverDrive cooperated with Amazon, the world’s biggest online bookseller, last year. Owners of Amazon’s Kindle e-reader who want to borrow e-books from libraries are now redirected to Amazon’s website, where they must use their Amazon account to secure a loan.
According to Pew, an opinion researcher library users are a perfect for market for Amazon. Late last year Amazon introduced its Kindle Owners’ Lending Library, which lets its best customers borrow free one of thousands of popular books each month.
Library supporters argue that book borrowers are also book buyers and that libraries are vital spaces for readers to discover new work. Many were cheered by a recent Pew survey, which found that more than half of Americans with library cards say they prefer to buy their e-books.
So publishers keep adjusting their lending arrangements in search of the right balance.
Random House raised its licensing prices earlier this year, and Harper Collins limits libraries to lending its titles 26 times.

4 . McKenzie grew up at a farmhouse. Initially, the fence around the property was old and had several large gaps, so I strengthened the bottom with chicken wire and thought all was well. McKenzie would spend his days frolicking (嬉戏) in the large yard while Connie and I were at work and Sophie was at school.
One day, while on a job in the area, I stopped home to visit. As I pulled up to the driveway, I saw McKenzie outside of the fence playing in the daisies, dancing and nosing at a large butterfly hovering just out of his reach. I watched McKenzie enjoying himself until, suddenly, he realized he wasn’t alone. He took one look at me and fled to a hole under the fence, wriggling (扭动) back into the yard. He ran around to the back of the house, the place where he was usually asleep when we came home. As I stood and watched, McKenzie then proceeded to come around the corner of the house, stretching as if he had just woken up. Then, continuing his act, he looked at me as if he had just noticed I was home and excitedly came up to the fence, where he sat in his “proud boy” stance (姿态), as if he had been good all day and was glad to see me! I laughed as I opened the gate, and then I stood and gave him a frown. With my hands on my hips, I asked the little faker where the hole was. To my surprise, he lowered his ears and dejectedly walked over to the spot in the fence he had earlier wriggled through and sat down, looking at me. I laughed so hard that I cried.

5 . China Science Daily announced Thursday that it has used software to automatically generate news stories about the latest discoveries from the world’s leading science journals. The robot science reporter, called “Xiaoke”, was co-created by the newspaper and researchers from Peking University in about half a year.
It is the latest case of Chinese news organizations using computer technology to create content. According to its inventors, Xiaoke has generated over 200 stories based on the English abstract of papers published in journals such as Science, Nature, Cell and the New England Journal of Medicine.
Before publication, the automatically generated articles will go through a review process. A group of scientists and the newspaper’s editors will check the content or give supplementary (补充的) information.
Zhang Mingwei, head of the program and vice editor-in-chief of the newspaper, said inventors would make Xiaoke a “cross-linguistic (跨语言的) academic secretary” to help Chinese scientists overcome language barriers and have easy and quick access to the latest scientific advances in English-language publication. Lead researcher Wan Xiaojun, of Peking University in charge of the system’s design and technology, stressed that the content generation tool could do far more than translation. According to Wan, Xiaoke is good at selecting complex words and sentences, which can help turn articles full of confusing technical terms into easy and readable news reports.
The readers of the robot reporter is not limited to professionals but also includes the general public. Science reporting is important in spreading information about discoveries and in popularizing knowledge to people.

7 . One rainy afternoon, I was on a crosstown bus when a young woman jumped on. She had a child with her who was about three or four years old. The bus was full, bumpy(颠簸的), and it soon got noisy, as her kid began crying — he was upset that he couldn't sit next to his mother. She looked embarrassed.
Then another woman, a little older, stood up and moved so that the mother and child could sit together. The mum smiled as a thank-you. And then three words came out of the older woman's mouth that raised the entire energy of that bus ride: “I've been there.”
Simple, undramatic, and honest. In that moment, it seemed to unite the diverse people of the city. Why? Because almost all experiences are shared human experiences. They're universal. We forget that as we go through life, focused on our own troubles and needs — which are actually less unique than we think.
Sometimes painful past experiences prevent us from wanting to open up to others because we don't want to revisit our own history. But a wonderful way to honor your past hurt is to help comfort another's current pain.
When I was a little girl, we lived on donations from local families and clothing from the " lost and found" baskets. It was shameful for me at the time — I lived in fear of being caught in a friend' s cast-off item.
Even when it was warmer, I refused to take off a layer in the classroom for this reason. Now I don't meet people who are in this exact situation, but I do notice when someone is struggling with financial shame or feels less than other people they meet. And I'm quick to say some version of, "I've been there."
Can the essence of these three words help you make a small difference right now? It can be as simple as volunteering your seat, sharing some helpful advice, or even lightening the mood with a joke when you notice that someone's uncomfortable — because we're all in this together.
1. What influence did the older woman's words have on the people around?| A．Causing discomfort. | B．Breaking long silence. |
| C．Creating a heated debate. | D．Inspiring common feelings. |
| A．They are mostly shared experiences. | B．They don't really matter to anyone' |
| C．They will be forgotten with time. | D．They are unique to each individual. |

8 . One of the most popular beliefs in parenting is the so-called Mozart effect, which says that listening to music by the Austrian composer Wolfgang Mozart can increase a child's intelligence. Some pregnant women have even gone so far as to play Mozart recordings on headphones pressed against their bellies. And it's not hard to see how Mozart's name became associated with accelerated development. He was history's greatest child genius, performing astonishing music for kings and queens at an age when many of us were content with tuneless singing "I'm a Little Teapot".
So, if you have kids or you're expecting to have them, how seriously should you take the Mozart effect? Will the child who doesn't listen to Mozart in the cradle (摇篮) be limited to an ordinary life? Are you a bad parent if your kids don't know about any works of Mozart?
Relax. There is no scientific evidence that listening to Mozart improves children's cognitive( 认 知 ) abilities. The whole idea comes from a small study done in 1993,which found that college students who listened to Mozart's Sonata for Two Pianos in D Major(K 448)showed some improvement in a test of spatial(空间的) skills.
This finding was later described as something extremely amazing by a musician, Don Campbell, in a book. Campbell's claims about the superpowers of Mozart's music were repeated endlessly in the media and fueled a craze for Mozart-based enrichment activities. In 1998.for example, the governor of Georgia in the USA requested funds to send classical-music CDs to all parents of newborns in the state.
Since then, scientists have examined the claim that Mozart increases intelligence and found no evidence for it. The original experiment with college students was reviewed in 1999,and the increase students' spatial skills was found to be insignificant. In 2007 the German Federal Ministry of Education and Research asked a team of experts to examine the scientific literature regarding Mozart development and they found no reason to believe that it increased intelligence.
1. Why do people relate Mozart to children's intelligence development?| A．Because he was a royal Austrian composer. |
| B．Because he owned extraordinary music talent. |
| C．Because he could perform music as a little child. |
| D．Because his music is suitable for pregnant women. |
| A．It added to the popularity of Mozart's music. |
| B．The finding was originally discovered by a musician. |

9 . What do extreme marathoners, mountain hikers and professional bicycle racers all have in common? They push their bodies to unsustainable (不可持续的) extremes of physical stress.
We tend to think there’s no limit to human physical achievements. But a new study, published in Science Advances, says there is a definite limit to human endurance (耐力). Beyond that, our bodies begin to break down.
To find the limit, a US research team tracked marathon runners over a five-month period, measuring competitors’ initial basal metabolic rates (BMR, 基础新陈代谢率) – the amount of energy they expend when they rest. Then they looked at how many calories(卡路里) each runner burned per day.
The team found that the maximum amount of energy a human can expend is 2.5 times of BMR. It equals 4,000 calories of energy per day. These calories can help a trained athlete to run about 42 kilometers in a day.
But people can’t keep using this amount of calories all the time. “You can do really intense stuff for a couple of days, but if you want to last longer then you have to dial it back,” US evolutionary anthropologist Herman Pontzer told the BBC.
Pontzer explained that the problem is our guts (消化道). “There’s … a limit to how many calories our guts can effectively absorb per day,” he said in the Daily Mail. At that point, the body is burning calories more quickly than it can absorb food and convert (转化) it into energy.
These new findings could help athletes to best work underneath this ceiling. For example, they could manage their daily exercise time based on their BMR, to get enough calories and keep going.
However, Pontzer’s team can’t rule out the possibility of someone breaking this limit. “So I guess it’s a challenge to elite endurance athletes,” said Pontzer. “Science works when you’re proven wrong. Maybe someone will break through that ceiling some day and show us what we’re missing.”
1. What did the US research team find in the new study?| A．One’s endurance can be improved through exercise. |
| B．A trained athlete can do intense activities for more than a week. |
| C．The average BMR for athletes is 4,000 calories of energy per day. |
| D．The energy one can expend is no more than 2.5 times of their BMR per day. |

| B．To show how our bodies produce energy. |
| C．To explain why there is a limit to human endurance. |
| D．To prove the importance of our guts to physical activities. |
| A．keep a more balanced diet |
| B．save time and reduce stress |
| C．arrange their training properly |
| D．improve their performance quickly |
| A．It’s possible that someone could break the endurance limit. |
| B．It’s no good trying to work above the 2.5x endurance ceiling. |
| C．Further data is needed to make the study’s results more accurate. |
| D．The 2.5x endurance ceiling is not a problem for many elite athletes. |
10 . Facts about novel corona virus: Prevention and control
l Keep distance with people when talking
The novel corona virus can be transmitted via droplets and fly 1 to 2 meters in the air before falling to the ground. Droplets can be transmitted far longer when sneezing and coughing than speaking, so apart from keeping 1 to 2 meters of distance, also remember to wear a mask when you are close to someone else.
l Washing hands can reduce risk of getting infected
Please wash your hands promptly and properly after touching elevator buttons or using cash. Do not touch your nose or mouth or rub your eyes before washing your hands. Do not use smart phones while eating.
l Receiving delivered packages at home not dangerous
Though the virus might be attached to the packaging of delivered items, the possibility of transmission through express delivery is extremely low. Before going out to take your delivery, remember to wear a mask. After removing the packaging, please wash your hands.
l Sun exposure cannot kill the virus
The temperature of sun light cannot reach 56℃, and the ultraviolet rays in sunlight cannot reach the intensity of ultraviolet lamps, so the virus can’t be killed by the sunlight. If you want to go out to get some sun, please wear a mask and take other protective measures.
l Taking a hot bath or using air conditioning cannot kill the virus
Although the virus is vulnerable to heat. It can only be inactivated after exposure to a 56°C temperature for over 30 minutes.
l Woolen fabric doesn’t retain virus longer
It is believed that the virus prefers smooth, non-porous surfaces and stays on woolen fabrics for a shorter time. At home or before going out, it is not necessary to consider which kind of material has less chance to absorb the virus—choosing comfortable clothes is enough.
After returning home, please wash your hands, sterilize the clothes and dry the clothes.
