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 . Fu Cong, a Chinese-born pianist, died on Monday at a hospital in London, where he had lived for many years.
A lover of classical music from a young age, Mr. Fu began taking piano lessons when he was 7. He made his first stage appearance in 1952. The concert caught the attention of officials in Beijing, who selected him to compete and tour in Eastern Europe. Mr. Fu soon moved to Poland, where he studied at the Warsaw Conservatory (音乐学校) on a scholarship. To prepare for the fifth Chopin Competition in Warsaw in 1955, he practiced so hard that he hurt his fingers and was nearly cut from the first round of the competition.
Mr. Fu was one of the first Chinese pianists to achieve global fame when he took third place in the International Chopin Piano Competition in Warsaw in 1955. He also won a special prize for his performance of Chopin's mazurkas. Almost overnight, he became a national hero. To China, Mr. Fu's recognition in a well-known international competition was evidence that the country could stand on its own artistically in the West. Chinese reporters came to interview Mr. Fu, while many others went to his father, Fu Lei, for advice on child-raising.
In 1981, a volume of letters written by his father, was published in China. Full of advice, encouragement, life teachings and strict paternal love, the book Fu Lei's Family Letters became a best-seller in China. Besides influencing a generation of Chinese, Mr. Fu's words resonated (引起共鸣) long after his death with the person for whom they were intended.
“My father had a saying that 'First you must be a person, then an artist, and then a musician, and only then can you be a pianist,'" Mr. Fu Cong once recalled in an interview. "Even now, I believe in this order-that it should be this way and that I am this way.”

3 . As more and more people speak the global language of English, Chinese, Spanish, and Arabic, other languages are rapidly disappearing. In fact, half of the 6,000-7,000 languages spoken around the world today will be likely to die out by the next century, according the United Nations Educational, Scientific, and Cultural Organization (UNESCO).
In an effort to prevent language loss, scholars from a number of organizations — UNESCO and National Geographic among them — have for many years been documenting dying languages and the cultures they reflect.
Mark Turin, a scientist at the Macmillan Center, Yale University, who specializes in the languages and oral traditions of the Himalayas, is following in that tradition. His recently published book, A Grammar of Thangmi and Their Culture, grows out of his experience living, working, and raising a family in a village in Nepal.
Documenting the Thangmi language and culture is just a starting point for Turin, who seeks to include other languages and oral traditions across the Himalayan reaches of India, Nepal, Bhutan, and China. But he is not content to simply record these voices before they disappear without record.
At the University of Cambridge Turin discovered a wealth of important materials —including photographs, films, tape recordings, and field notes — which had remained unstudied and were badly in need of care and protection. Now, through the two organizations that he has founded — the Digital Himalaya Project and the World Oral Literature Project — Turin has started a campaign to make such documents, found in libraries and stores around the world, available not just to schools but to the younger generations of communities from whom the materials were originally collected. Thanks to digital technology and the widely available Internet, Turin notes, the endangered languages can be saved and reconnected with speech communities.

4 . “I had no intention to adopt a cat that day. I just liked being around animals.” Miranda says. But when she saw Nala in her metal cage, “We made eye contact and I couldn't resist（抗拒）her big blue eyes.” At that point, “Nala was so small. I asked the shelter if I could hold her. Once had Nala in my arms, Nala looked up at me and licked（舔）my face.” And that was when she knew she had to take this kitty home.
Still, Miranda never imagined Nala would become an Insta-star. “I started Nala’s Instagram account in 2012 as a way to share photos with my close friends and family in Thailand,” she explained. The possibility of Nala gaining attention beyond that small group of people hadn’t occurred to her until it happened.
Miranda says, “Each time Nala’s photo was featured on Instagram’s popular page, her account would gain 1,000 new followers.” From there, Nala’s popularity snowballed. Large nationwide brands messaged Miranda about hiring Nala to do ads. “This took us by surprise because we couldn’t believe that a big brand wanted to pay them to take photos with their products next to Nala.”
Nala started life out in a shelter, just waiting to be loved like many other animals that were abandoned. Today that dream has surely come true. Nala has over 4 million followers on Instagram, which earned her the title “Guinness World Records Most Popular Cat on Instagram.”
In addition to managing her Insta fame, Nala is being asked to test various cat food brands. More importantly, “Nala is our chance to share the love to help create a better life for other animals, so they can grow well and bring joy to the world like Nala has.”
1. What is the first paragraph mainly about?| A．Visits to a shelter. | B．Love at first sight. |
| C．Power of blue eyes. | D．Duty to adopt cats. |
| A．To meet Nala’s needs. | B．To help Nala be a sta. |

| A．Satisfied | B．Amazed. | C．Upset. | D．Disappointed |
| A．Being well treated like many of her kind. | B．Starting life in the shelter. |
| C．Gaining chances to earn money. | D．Being raised by Instagram fans. |
5 . Several years ago, when someone used camera covers to protect against possible monitoring, it was not popular to talk about it. Today, people use various types of tapes to cover the web cameras and microphones.
There are many types of spyware that can dive into our devices and secretly spy on them, recording everything they do. Such programs may infect not only computers but also smartphones. Your data may be used by hackers who will try to request money for not exposing your private information or by companies like NSO Group who created the Pegasus spyware to “provide authorized governments with technology that helps struggle against terror and crime”.
In my opinion, the described protection technique is highly overestimated. Users tape cameras and microphones due to the lack of understanding of how their devices work and how malware(恶意软件)works. Hackers and even secret services do not have enough resources to monitor all victims using cameras or microphones. If they need to yet any information, they get it by sending a targeted malware to your device, which will not be stopped by the tapes. Such a virus will find what to steal -from personal photos and videos to passwords from social networks, browser history, bank accounts and much more.
It is unwise to believe that attackers will not be able to find a way to spy on you, even if the device, discharged to zero, can still deliver data about your location, using the smartphones of the surrounding people as signal repeaters. Let us face it. we live in an era when it is extremely difficult to hide something and a piece of tape is clearly not the most useful tool in the struggle for your privacy.
Again, to be able to spy on you, attackers need to plant malware in your device. To prevent malware from entering your device, do not click suspected links and email attachments. Use strong passwords for email, social media and online banking accounts.
1. What does the underlined word “them” in paragraph 2 refer to?| A．Cameras. |
| B．Types. |
| C．Programs. |
| D．Devices. |
| A．group of hackers. |
| B．A company developing spyware. |
| C．A group of terrorists and criminals. |
| D．A company fighting against crime. |
| A．People know little about their devices. |
| B．Hackers have no access to others. |
| C．It hardly prevents malware from getting privacy. |
| D．It can't cover the cameras completely. |
| A．Protecting privacy on devices. |
| B．Rising trend of using tapes. |
| C．Monitoring devices via cameras. |
| D．Avoiding clicking distrustful links. |
6 . Everyone knows you must exercise regularly to keep good health. Indeed, staying physically fit is a big part of our culture. We consider (or rightly so) that healthy people are attractive people. Since most of us want to be attractive, there is no shortage of exercise clubs, training videos, magazines and books offering to help us stay physically fit.
Unfortunately, however, our culture doesn’t place the same emphasis on mental fitness. Although we tend to like men and women with strong, healthy-looking bodies, we don’t have the same degree of respect or attraction for smart, educated, mentally healthy people. This is a pity, because there are great rewards for people who have developed the ability to think well.
If your mind is well trained and flexible, you will be able to understand a great deal of what happens around you. And if you are also well educated-that is, if you understand basic science, mathematics, music, art, literature, history and so on—you will find it much easier to make good decisions throughout your life. Over the long run, this leads to a sense of control over your destiny (命运) and a much better life than otherwise (in another way).
People who are poorly educated or who don’t think well—that is, people who are not mentally fit—see things differently. Their world is controlled by mysterious, often malevolent (恶意的) forces. Such people live within a system they will never master, forced to follow rules they will never understand. Although it may not be obvious, most spend their lives being manipulated (控制) by others. They are told what to do, what to think, how to spend their money, and what they should and should not aspire (渴望) to in life.
In my opinion, if you want to live well, you must be able to use your mind well. For this reason, I want you to be able to concentrate, to solve problems, to understand complex ideas, and to think clearly and quickly. Such skills will make it easier for you to make informed decisions, understand current events, choose good friends, manage your money well, make wise long-term decisions and appreciate music, art and literature.
The key to developing such skills is to enjoy learning, and to have the ability and motivation to teach yourself.

7 . Social media is taking over our lives: Facebook, Instagram, Twitter and now, TikTok. These social media platforms have transformed from a way to stay connected to an industry where even kids can make money off their posts. While this may seem like another opportunistic innovation, it’s really full of hidden false realities.
The median income (中位收入) recorded in the United States of America was about $63,000 in 2018. TikTokers can make anywhere from $50,000 to $150,000 for a TikTok brand partnership, and TikTokers with over a million followers can make up to $30,000 a month — $360,000 a year. They are making more than the average person trying to feed their family and keep a roof over their heads, simply by posting a 15-second video.
This is mad in more ways than one. Not only is it an overpaid “job”, it promotes undeserved admiration from viewers and a false sense of reality. Many of these famous TikTokers are still teens, and the effects of fame at such an early stage in life might cause issues later in life, such as mental illness. Teens between the ages of 13 and 17 make up 27% of TikTok viewers, who can be easily influenced by what they are watching. They can put a false sense of self-value into who they look up to and what they represent: money, fame, being considered conventionally attractive.
While TikTok has become a great tool for marketing, it’s important to understand how this content affects young viewers. If we’re constantly consuming content that hsows us all we need to do to be successful is be conventionally attractive and post a 15-second video featuring a new dance, it will challenge our knowledge of what really makes someone successful and will in turn affect our individual work ethics (伦理). What about the people who miss birthdays and family holidays due to their jobs and aren’t getting paid nearly as much as these TikTokers?
Richard Colyer, president and creator of Metaphor, Inc., had his own view on this issue.
“It sounds great that kids can make money for doing the latest dance moves in a 15-second video, but we should feed the minds of kids and not just their bank accounts. TikTok can be great if used properly. Money alone is not good, technology alone is not good and connectedness can be bad if it’s only online.”
Again, as a fellow consumer of TikTok, I do enjoy the app when I have some time to kill and need a good laugh. I’m not against someone making a living on entertainment, but what does getting famous of a 15-second video teach young people?

8 . In my everyday life, I am on an ongoing journey to figure out different ways to reduce my carbon footprint on the planet. A carbon footprint is the measure of influence our activities have on the environment, in particular climate change. It is calculated by the amount of greenhouse gas we produce in our daily lives. Fortunately, nowadays it is much easier to make eco-friendly lifestyle choices than, let's say, 20 years ago. But one question has been on my mind a lot lately: is it better to buy new eco-friendly products or used traditionally produced goods?
After doing some research, I have decided that some things are better new and others are better used. Let me try to explain.
A carbon footprint is made up of two parts, the primary footprint and the secondary footprint. The primary footprint is a measure of our direct emissions(排放)of carbon dioxide(CO2)from the burning of fuels, including household energy consumption and transportation. The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we use-those related to their production and breakdown.
Based on this understanding, we have a good deal of control and responsibility over our carbon footprint. Things like dishes, clothes and furniture fall into the “secondary footprint” group, so less is more and we can focus on finding used goods to avoid the added production. However, for the car and the other appliances(设备)that we need we can go with new, energy-saving models. I heard somewhere that electronics and appliances give off 90% of their carbon footprint after they leave the factory. So it seems most reasonable to go for the energy-saving models. The main concern here is the amount of energy that goes into the making of new products and whether or not that extra carbon is worth the footprint the product will make once it gets to you.
1. What is the text mainly about?| A．What appliances to buy to save energy. |
| B．What a carbon footprint means in our life. |
| C．How to identify different carbon footprints. |
| D．How to make eco-friendly lifestyle choices. |
| A．It is related to our consumption of fuels. |
| B．It is made when we are buying the products. |
| C．It is less harmful than the primary carbon footprint. |
| D．It is counted as ours though not directly made by us. |
| A．Using second-hand textbooks. | B．Using old and expensive cars. |
| C．Buying new but cheap clothes. | D．Buying new wooden furniture. |
| A．using the product | B．recycling the product |
| C．making the product | D．transporting the product |
9 . 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.

10 . It’s a really good idea to visit colleges before you apply because their websites can all look and sound the same. Nothing will give you the sense of what it will actually be like to live on a college campus (校园) like visiting and seeing for yourself the dorms, classrooms and athletic equipment (器材) and, of course, the students. It seems a little crazy once senior year hits to find the time to visit college campuses, and it can also be pricey if the schools you are applying to happen to be more than a car ride away. But keep in mind that you are making a decision about the next four years of your life, and do all the research you can to make sure you are making the right one.
There’s no excuse not to visit the schools in your local area. In fact, a lot of college applications even ask if you have visited campus, and obviously, if you live across the country that won’t be as much of a possibility, but if you live nearby, go check it out! If campus visits aren’t going to happen before you apply, at the very least you should find some time between applying and getting your acceptance letters to visit the schools you’d like to attend. It can save you a lot of heartache if you rule out now the things that you don’t like about certain campuses, things that you wouldn’t know unless you actually visit.
Now, if time and money are making it impossible, then check out the online college fairs at College Week Live. It’s a chance to chat online with admissions (招生) officers, students, and college counselors (倾问), and it won’t cost you a penny! You can register (注册) for its online college fair at collegeweeklive.com. While visiting an online college fair can’t take the place of an actual campus visit, it can be a very useful tool that along with all your other research will help you make a wise decision about which colleges you’d like to attend.
