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.”

3 . Technology is a double-edged sword(双刃剑)— while it brings convenience, it also brings new problems. The sword of “social media” even has its preference: It cuts deeper into girls than boys.
Jean Twenge, a professor at San Diego State University in the US, recently discovered an alarming trend: Since 2010, the number of teenage girls who suffer from major depression, showing signs like self-harm and suicide (自杀), has increased much faster than that of boys. It is social media again that is to blame.
Statistically, girls use social media more than boys. Boys tend to spend their screen time on games, where they talk to their teammates through headphones. Though not directly, this still counts as real human contact. Girls, however, simply type and browse through posts, which is a much more isolated (孤立的) experience. “They're not having a real-time conversation with someone most of the time,” Mary Fristad, psychologist at The Ohio State University, told NPR.
And when it comes to online shaming, girls are also more vulnerable than boys. “Girls face more pressure about their appearance, which could be exacerbated (加重) by social media,” wrote Twenge. Shannon McLaughlin, for example, is an 18-year-old from Blackburn College in the US. She shared with the Guardian how social media made her feel depressed.
But McLaughlin found a solution. She started volunteering with the National Citizen Service, where she made face-to-face contact with people. "It's so easy to forget the importance of real connections when we have hundreds of people that we' re trying to impress at our fingertips," she told the Guardian. And she hopes that others "look up from their phones and focus more on the world around them".

4 . Dogs are often referred to as “man’s best friend”. But MacKenzie, a four-pound chihuahua, who was named winner of the 2020 American Hero Dog Competition on October 19, 2020, is making the world a better place for humans and animals alike.
In its tenth year in 2020, the annual contest is the brainchild of American Humane Association, the country’s first national charitable organization founded for the safety and well-being of animals. Often called the “Oscars for dogs”, the award recognizes dogs who make extremely great contributions (贡献) to society.
The competition of 2020 attracted over 400 entries from across the country. These heroic dogs have gone above the call of duty, saving lives, comforting the ill and aged and reminding us of the powerful, age-old ties between animals and people. While all were impressive, it was tiny MacKenzie who won the judges’ hearts.
MacKenzie’s path to stardom was not easy. Born with a mouth disability, she had to be fed through a tube (管子) for the first year of her life. Despite her own struggles, she always seemed to think more of other animals in need. “Never have I seen such a will to live. Though sick, she carefully looked after the baby animals at the rescue (救助) center,” said her caretaker.
A life-saving operation performed in 2014 gave MacKenzie the ability to eat independently. The seven-year-old chihuahua is now working for the Mia Foundations New York-based charitable organization that rescues and nurses animals with inborn disabilities. The chihuahua does an excellent job and has raised various animals. She plays nurse, cleans, comforts and hugs them, acting as their mother and teaching them how to socialize, play and have good manners.
In addition to her role as an animal caretaker, MacKenzie also visits schools to educate kids about the importance of accepting physical differences in both animals and people. Her heart-warming and inspiring story makes her a worthy receiver of Americans top dog honor!

5 . 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.”

6 . Math holidays everyone should know
In recent years mathematicians and scientists have begun campaigns to mark certain dates in celebration of significant principles and here are a few to add to your calendar
Mole Day
Mole Day is celebrated yearly on Oct. 23 from 6: 02 a.m to 6: 02 p.m.. The idea of a celebratory day was put forward by a chemistry teacher in 1991 and has been honored every year since. It celebrates Avogadro's Number, which is a basic measuring unit in chemistry. Each Mole Day has a specific theme.
Pi Day
The grandaddy of mathematical and scientific holidays, however, falls every year on Mar. 14. The date, 3/14, represents the first three numerals in the calculation of pi, so the date is known annually as Pi Day.
Pi Day was founded in 1988 by a physicist. The observations spread to the point where on Mar. 12, 2009, the U.S. House of Representatives passed a resolution declaring Mar. 14 as National Pi Day.
Fibonacci Day
Nov. 23 marks Fibonacci Day, a special day that celebrates the man known as Fibonacci who developed a mathematical idea called the Fibonacci Sequence, in which every number is the sum of the previous two numbers. So, for example. 11/23 marks the day because 1+1 equals 2, and then 1+2 equals 3（the date being the 23rd）.
Square Root Day
Square Root Day is a holiday that heartily honors those dates where the combination of day and month and year form square roots: e.g. 2/2/04 and 3/3/09. The last Square Root Day was 4/4/16. The holiday was created by a high school teacher Ron Gordon. Square Root Day has its own website where celebrants can gather before the next holiday.
1. How is Mole Day similar with Pi Day?| A．They both have themes. | B．They are yearly holidays. |
| C．They fall on the same day. | D．They are created by a teacher. |
| A．Mole Day. | B．Pi Day. | C．Fibonacci Day. | D．Square Root Day. |
| A．10/23/22. | B．11/23/23. | C．3/12/29. | D．5/5/25. |
7 . “Human activity has wiped out two-thirds of the world’s wildlife since 1970,” CNN reported on September 10, 2020. Later that month, the Guardian reported that “40 percent of the world’s plant species are at risk of extinction”. Stanford biologist Paul Ehrlich and his colleagues argued that “the ongoing sixth mass extinction may be the most serious environmental threat to the persistence of civilization”. Around the same time, the Daily Mail warned that “human civilization stands a 90 percent chance of collapse within decades due to deforestation”.
These horrible calculations and projections come from authoritative-sounding reports issued by international agencies, conservation groups, and peer-reviewed scientific journals. But is the future of wild nature and human civilization really so poor?
Data from uncontroversial mainstream sources strongly indicate that both humanity and the natural world are likely to be flourishing rather than collapsing at the end of this century. Humanity is becoming an urban species, and that’s good for the environment, since urban dwellers generally use less electricity, produce less globe-warming carbon dioxide, and have smaller land footprints than people living in the countryside. By 2100, it is estimated that 85 percent of people will be city dwellers, which would leave only 1.2 billion still living in the countryside. That means more space for the wildlife and less pollution from the agriculture.
The global tree-covering area increased by 865,000 square miles between 1982 and 2016. The researchers found that gains in forest area in the mild, subtropical and northern climatic zones are offsetting declines in the tropics. The Maryland researchers owe much of that increase to “natural afforestation on abandoned agricultural land”. “Furthermore, forests in mountainous regions are expanding as climate warming enables trees to grow at higher altitudes,” they added.
Humanity does face big environmental challenges in the coming century. But the scientific and economic evidence shows that most of the trends are positive or can be turned in positive direction by human wisdom. Rather than an age of extinction, the 21st century promises to be an era of environmental renewal.

8 . It is a question people have been asking for ages. Is there a way to turn back the aging process?
For centuries, people have been looking for a “fountain of youth”. The idea is that if you find a magical fountain, and drink from its waters, you will not age.
Researchers in New York did not find an actual fountain of youth, but they may have found a way to turn back the aging process. It appears the answer may be hidden right between your eyes, in an area called the hypothalamus (下丘脑). The hypothalamus is part of your brain. It controls important activities within the body.
Researchers at New York’s Albert Einstein College of Medicine found that hypothalamus neural (神经的) stem cells also influence how fast aging takes place in the body.
What are stem cells(干细胞)? They are simple cells that can develop into specialized cells, like blood or skin cells. Stem cells can also repair damaged tissues and organs.
Dongsheng Cai is a professor at the Albert Einstein College of Medicine. He was the lead researcher in a study on aging in mice. He and his team reported their findings in the journal Nature, Cai explained when hypothalamus function is in decline, particularly the loss of hypothalamus stem cells, and this protection against the aging development is lost. it eventually leads to aging.
Using this information, the researchers began trying to activate, or energize, the hypothalamus laboratory mice. They did this by injecting the animals with stem cells, Later, the researchers examined tissues and tested for changes in behavior. They looked for changes in the strength and coordination (协调) of the animals muscles. They also studied the social behavior and cognitive ability of the mice. The researchers say the results show that the treatment slowed aging in the animals, Cai says injecting middle-aged mice with stem cells from younger mice helped the older animals live longer.
But these results were just from studying mice in a laboratory. If the mice can live longer, does that mean people could have longer lives? The next step is to see if the anti-aging effects also work in.

9 . The public nowadays has a misunderstanding of forest fires, believing that fires should be kept out of every type of forest. Many of us can recall Smoky the Bear's famous warning: “Remember, only YOU can prevent forest fires”. However, that's not always the case. Under the right conditions, and when conducted safely, fire can create many environmental benefits as well as help prevent larger, uncontrollable wildfires.
After a forest fire, many wildlife species will move into recently burned areas to feed on these newly available foods. Some reptiles and amphibians such as the pine (松树） snake prefer forests frequently burned by fire. As Herbert Stoddard put it, “One of the most harmful things modern man has done to birds has been his attempt to exclude fire from fire-type pine forests. Within a few years most forests choke up with bushes, lose their prairie-like vegetation (草原般植被） and can no longer support birds dependent on periodic burning for their food supply and proper cover.”
If you are asked to picture the forest floor, what do you see? Pine needles, cones, leaves, branches might come to mind-all sources of fuel. If these fuel sources build up without any type of removal, the 'fuel load' can lead to fires catastrophic to forests and people alike. In contrast, prescribed fire can be used by forest professionals every couple of years to keep forest fuels at an appropriate and manageable level. They can also minimize the spread of pest insects and disease and remove unwanted tree and plant species. Plus, they can create and maintain important wildlife habitats rich in grasses and promote the growth of trees, wildflowers and other various plants.
Many organizations and agencies work to promote fire on the landscape when and where appropriate. Smokey Bear even has an updated warning: “Only You can Prevent Wildfires,” as the Forest Service has over the last few decades developed policies and procedures to include prescribed fire as a management tool, as well as continuing their work to prevent and fight wildfires.

10 . One summer during high school, my mom volunteered me to help Grandpa research our family tree. Great, I thought, imagining hours spent pawing through dusty, rotting boxes and listening to boring stories about people I didn't know. "You'll be surprised," my mom promised, "Family histories can be very interesting."
In truth, Grandpa didn't want to limit my work to just research, hoping to also preserve our family memories. He'd discovered a computer program that helps digitally scan old pictures and letters to preserve their contents before they crumble from old age. Grandpa wanted me to help him connect the scanner and set up the computer program. He could type documents and send emails, but had never used a scanner.
Soon after, I became fascinated with my relatives' lives. I asked Grandpa to tell the story behind every picture and letter we scanned. The stories, which turned out not to be boring at all, helped me not only understand but also relate to my relatives. I became so hungry for more information that Grandpa needed additional props to keep me satisfied. He showed me a chest filled with random stuff, all covered in dust.
Perusing through their belongings, I felt I was opening a window into the world of my relatives, a world long since gone. Grandpa showed me a bundle of letters he had sent to Grandma from the front lines of World War II and I could almost smell the gunpowder. I turned the pages of my great-grandmother's recipe book and could picture her cooking in her kitchen. All of the people who had been merely names to me now had faces to match.
Later, Grandpa admitted, "I probably could have done this project myself. I just wanted someone to share it with." I can't thank him enough for sharing the experience and making me appreciate the family members who have made me the person I am. I will cherish family memories and hope that someday will be able to pass them down to my own grandchildren.
