1 . The history of microbiology begins with Dutch cloth maker named Antoni van Leeuwenhoek, a man of no formal scientific education. In the late 1600s. Leeuwenhoek, inspired by the magnifying lenses（放大镜）he used to examine cloth, built some of the first-microscopes. He developed technique to improve the quality of tiny, rounded lenses, some of which could magnify an object up to 270 times. After removing some plaque from between his teeth and examining it under a lens, Leeuwenhoek found tiny twisting creatures, which he called “animalcules”.
His observations, which he reported to the Royal Society of London, are among the first descriptions of microbes（微生物）. Leeuwenhoek discovered an entire universe invisible to the human eye. He found different microbes in samples of pond water, rain water, and human blood. He gave the first description of red blood cells, observed plant tissue, examined muscle, and investigated the life cycle of insects.
Nearly two hundred years later, Leeuwenhock’s discovery of microbes helped French chemist and biologist Louis Pasteur to develop his “theory of disease”. This concept suggested that disease originates from tiny organisms attacking and weakening the body. Pasteur’s theory later helped doctors to fight infectious diseases including anthrax, diphtheria, polio, smallpox, tetanus, and typhoid. All these breakthroughs were the result of Leeuwenhoek’s original work. Leeuwenhoek did not foresee this legacy.
In a 1716 letter, he described his contribution to science this way: “My work, which I’ve done for a long time, was not pursued in order to gain the praise I now enjoy, but chiefly from a strong desire for knowledge, which I notice resides in me more than in most other men. And therefore; whenever I found out anything remarkable, I have thought it my duty to put down my discovery on paper, so that the scientific community might be informed thereof.”

2 . Every day around the world, thousands of people with little or no scholarly training in art history walk into museums. They may or may not read notice boards that share relevant information of the artworks or artists. Imagine, before being permitted to direct their eyeballs to the art on the walls, museum visitors were required to read a 15-or 20- page introduction to each piece or each artist. How many people would go to museums if that were the case?
Yet this seems to be the expectation when it comes to reading classic literature. Classic novels typically come with 15- or 20-page introductions, which often include spoilers, assuming that readers do not come to classic books to discover, be absorbed in, and be surprised by the story world. Also, evidently, we mustn’t read classics alone, without experts guiding our experiences.
However, classic literature is in a unique position to show us that we’re not alone in our pains and joys. By taking us out of our time, classic books free us to see beyond the set of beliefs we stick to and to connect human experiences that remain alive across time and place. What could be more grounding, more comforting, than seeing ourselves in the battles, longings, and pleasures that have played out across hundreds, thousands of years of human history? Our personal engagement (参与) is the first step of a longer journey of discovery that deepens our knowledge and understanding of ourselves and our world. We may, for example, feel for Hester Prynne from Nathaniel Hawthorne’s The Scarlet Letter though we feel hopeless of the world she lived in.
While we’re letting go of things, let’s stop worrying about understanding everything. We can’t. It will be fun if we embrace (拥抱) curiosity, the pleasure of working out a mystery, and our common relationships as humans. We can feel, for example, the power of self-sacrifice (牺牲) in Charles Dickens’ A Tale of Two Cities even when we lack full understanding of the cultural references and language.

3 . Emory Jensen, a 10-year-old fourth-grader, ran her fingers across a wall covered in artwork as she walked through an art exhibit. “It’s something that would get me in trouble or kicked out elsewhere,” she said unbelievably.
But Emory, who is unable to see, wasn’t kicked out, because it wasn’t at a typical art museum, but at the fully immersive (沉浸式的) art experience called “dreamscapes” as part of a field trip designed to help expose blind students to art. “We can all just feel it and it’s not what we can only look at,” she continued. “It’s awesome. The experience is like that in Alice in Wonderland.” The student also said she wanted to visit again with her cousin who suffers the same inborn eyesight problem.
“Most of these students probably have never been able to go to an art museum or really get to experience what art is,” said Kate Borg, director of blind campus programs. Art is typically focused on visuals, but “dreamscapes” is aimed at more. Sight, touch and smell are a big part of it, as well as emotional feelings. It uses different sounds, smells and substances (物质) in the artwork and allows people to walk through spaces with different themes.
Some staff were blown away to watch the children experience the art. “I couldn’t hold back my tears,” said Andrea Silva, “dreamscapes” manager. “I’ve never seen a visitor so lost in and curious about the art. We wanted it to be accessible to everyone, including and especially kids.”
Accessibility for art is vital, Borg said. “We read research after research that talks about creativity and art being so important for children in their development and growth,” she said. “And just because a child is blind or visually impaired (受损的) doesn’t mean that they shouldn’t have the same opportunity. They absolutely need to be close to art, and we have to be a little more creative in making sure we provide that.”
1. What can be learned about “dreamscapes”?| A．It is open to the students only. | B．It is focused on various senses. |
| C．It is built with special materials. | D．It is decorated to look like a fantasy world. |
| A．Touched. | B．Curious. | C．Proud. | D．Puzzled. |
| A．The necessity for children to research art. |
| B．The way to get children to think creatively. |
| C．The reason to help blind kids get access to art. |
| D．The importance for blind kids to develop overall. |
4 . A 15-year-old scientist and inventor has been named as Time's first ever Kid of the Year.
Rao is a high school student from Colorado. She was chosen from 5,000 U.S.-based nominees ( 提 名 ). Time said in a statement that Rao stood out for her ability to apply scientific ideas to real-world problems and her efforts to motivate other kids to take up their own causes. Rao told the Associated Press that the prize is “nothing that I could have ever imagined. And I'm so grateful and just so excited that we're really taking a look at the upcoming generation and our generation, since the future is in our hands.” She insists that starting out small doesn't matter, as long as you're enthusiastic about it.
It's just the latest recognition for the teenager, who was named last year to the Forbes 30 Under 30 list. Rao won praise in 2017 after she developed a portable device（设备） to detect lead (铅) in water. She went on to cooperate with scientists in the water industry to try to get the device on the market.
The young scientist has also developed an app called Kindly that uses artificial intelligence to help prevent cyberbullying (网络欺凌). It allows teens to type in a word or phrase to find out if the words they're using are hurtful and amount to（等于）bullying, and thus should be avoided.
In an interview with Time, Rao said that her pursuits（追求） in science started early as a way to improve conditions in society. In a world where science is increasingly questioned or challenged, Rao insists that its pursuit is an important act of kindness. It is the best way that a younger generation can better the world. Science and technology are being employed as never before to handle various issues, such as global warming, the outbreak of disease and so on, she noted.
“We have science in everything we're involved in, and I think that's the biggest thing to put out there, that science is cool, invention is cool, and anybody can be an inventor," Rao said.“ Anybody can do science.
1. What is one of the reasons for Rao being honored by Time?| A．The up-to-date ideas she had come up with. |
| B．The large amounts of time she had devoted. |
| C．The influence she has on young generations. |

| A．functional | B．environment-friendly |
| C．efficient | D．money-saving |
| A．Her tolerance for problems. | B．Her amazing brain power. |
| C．Her exposure to challenges. | D．Her concern about society. |
| A．High School Student Struggling for Big Dream |
| B．Young Scientist Named TIME's Kid of the Year |
| C．Scientific Achievements Applied to Our Real Life |
| D．Advanced Inventions Used in Bettering the World |
5 . Asia’s architectural treasures, from a Buddhist monastery in Afghanistan to an ancient city in China, are under threat due to economic development, poor technical resources, war and tourism, according to experts.
The Global Heritage Fund named 10 sites facing the loss and destruction impossible to recover. “These 10 sites represent only a small part of the endangered treasures across Asia and the rest of the developing world,” Jeff Morgan, executive director of the fund, said.
“We’re looking at these millennial ( 千年的) civilizations leaping into the 21st century at a kind of pace that is unheard of.” said Vishakha N. Desai, president of the Asia Society, which hosted a conference based on the report. He mentioned the pressures of rapidly modernizing Asia on the architectural treasures.
Kuanghan Li, head of Global Heritage Fund’s China program, underlined the importance in a presentation on work to preserve Pingyao, one of China’s last surviving walled cities. But “Up to 20 years ago, there were hundreds of similar walled cities left in China.” she said. “The majority of them have been destroyed.”
Experts said that global architectural preservation efforts are poorly balanced and targeted, with the UN cultural body UNESCO focusing almost entirely on sites in already rich European countries, rather than in places like Latin America or Asia. More than 80 percent of UNESCO World Heritage sites are located in the 10 richest states, the Global Heritage Fund said.
Elsewhere, “Heritage is being undervalued.” Morgan said, warning that the endangered sites were sure to vanish without quick help. “We’re going to lose them on our watch in the next 10 years.”
1. According to Jeff Morgan, UNESCO should ______.| A．take effective measures to stop wars |
| B．attempt to strengthen global cooperation |
| C．pay equal attention to Asia’s heritage protection |
| D．establish a clear goal of architectural preservation efforts |
| A．To praise the efforts by the Global Heritage Fund. |

| D．To stress the necessity of immediate action on heritage protection. |
| A．Disappear. | B．Survive. | C．Remove. | D．Recover. |
| A．Asia’s Relics in Ruins: Keeping Balance between Progress and Protection |
| B．Asia’s Heritage in Danger: Saving Disappearing Architectural Treasures |
| C．World’s Civilization Progress under Pressure: Making Global Efforts |
| D．World’s Resources under Threat: Raising Awareness of Preservation |
6 . One day about eight years ago in the departure lounge (休息室) of a flight from New York's LaGuardia airport to O'Hare in Chicago, I found a young boy in tears and his mother at his side also appeared upset, I walked to them and invited them to our VIP lounge.
As it turned out, the boy, Miles and his mom were returning to their home in Kansas City. Miles has had some health problems. Though he had received more than thirty operations in a Jewish Hospital in New York, he would be back for more.
Miles enjoyed spending his time in our VIP lounge looking at the entire wall filled with the pictures of many celebrities (名人) who often came to our office. We soon added Miles' picture to the wall among those celebrities.
Among the celebrities, Miles like the country singer Garth Brooks best. Miles would just sit and stare at Garth's picture,
One day, Mr. Brooks was waiting in the lounge for his flight. As he looked at the collection of photographs, Garth asked about the youngster with the big smile. We told him about Miles. We also told him how much Miles loved and respected (尊重) him. He nodded and left.
About six months later, Garth was going to be performing in Kansas City and he asked our workers to help him get in touch with the family. He wanted Miles to be his guest. That evening, not only did Miles sit in the front row, but he and Garth also had a private meeting after the performance.
Although Miles would receive many more treatments after that special evening, his smile greeted us with every following visit. The face of a sick boy was changed by the joy of a stranger.

7 . 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.

8 . Many families take their children on vacation. They will usually travel for a few days or weeks during school breaks. But Julie and Tim Smith planned a longer vacation with their two children. The Smith family is on a one-year trip around the world. They plan to visit 30 countries in all. Right now, the four travelers are about halfway through their trip. Ms. Smith says they are trying to see as much of the world as they can.
Mr. Smith says one of the most interesting experiences of the trip has been meeting new people. He says people have been extremely friendly, very welcoming and love their kids. Eleven-year-old Tyler says he has enjoyed learning about the people they have met. He said, "I learned in Africa that people have very different lifestyles than in America." His sister, 9-year-old Kara, discovered that she liked Thai food. Ms. Smith says that the trip teaches the children a lot.
It took the family a year to prepare for the trip. They had to sell their house and cars. Ms. Smith left her job and her husband is using unpaid leave. They carry small bags filled with lightweight clothing and whatever else they need. Ms. Smith says she enjoys being able to carry everything she needs on her back. She says she does not miss the things she has back home. "What has become more important is making these memories as a family and taking those with us instead."
The Smiths will continue to head east for the next six months.

9 . How to Show Good Sportsmanship
Sportsmanship is behaviour and attitudes that show respect for the rules of a game and for the other players. But how to show good sportsmanship in detail?
Method 1: Interacting with Opponents
Don’t trash talk. When your competitive juices start flowing, it may be tempting to call members of the other team names or make fun of them. But you can’t win a game by running your mouth, and it only makes you look desperate.
Respect the other team’s effort.
Method 2:
Be a team player. Even if you’re the best athlete on the field, you can’t win a game without your teammates. Everyone should share in team responsibilities, and do their part to ensure that the team is successful.
Support your teammates. Being a good sport means that you’re just as happy with their success as your own.
Listen to your coach. He or she is looking out for the good of the team, and sometimes, that means your role may be changed. Showing good sportsmanship means placing the team’s needs above your own, so you should trust the coach’s judgement.
| A．Respect the opponents |
| B．Control your temper |
| C．Relating to Teammates |
| D．Showing good sportsmanship may seem difficult at times |
| E．You shouldn’t care about your own performance more than the team |
| F．Whether they’re outplaying you or unable to keep up with your team |
| G．You may actually be able to learn something from your opponent |
10 . Ya Ting had taken me under her wing after hearing me speaking Chinese in a hotel in Lijiang．She had been hitchhiking(搭便车旅行) around China for months．She invited me to travel with her, which was how we ended up on the side of the road looking for a ride to the Tiger Leaping Gorge．Within 20 minutes, we had our first ride．The driver couldn’t take us all the way and ended up dropping us at a freeway crossroads．As a new hitchhiker, I thought that would be the end of our luck, but almost immediately we got another ride．
Our most unforgettable ride was when a twenty－something kid picked us up．He couldn’t take us the whole way so his uncle bought us lunch and a bus ticket for the rest of the journey．He felt it was his duty to help us find a way to complete our trip．It brought tears of joy and thankfulness to my eyes．This was the first time I understood how guests are respected(受尊重) in China．
A few weeks later, we said goodbye．I thought we had been so lucky because we had been a local(本地人) and a foreigner travelling together．But now Ya Ting was no longer around to do the talking, nor did I have someone to depend on if something went wrong．When I stood by a highway in Sichuan, I knew all about the difficulties before me．Now I was just a strange foreigner on her own who suddenly had to manage with poor Chinese．
After about 30 minutes, a couple picked me up and took me the whole eight hours to Chengdu．We ate lunch on the way, and they refused to allow me to pay for any of it, which I had come to learn was typical(特有的) of Chinese culture．This made me believe that people weren’t being friendly because of Ya Ting．
