1 . Barbara McClintock was one of the most important scientists of the 20th century. She made important discoveries about genes and chromosomes(染色体).
Barbara McClintock was born in 1902 in Hartford, Connecticut. Her family moved to the Brooklyn area of New York City in 1908. Barbara was an active child with interests in sports and music. She also developed an interest in science.
She studied science at Cornell University in Ithaca, New York. Barbara was among a small number of undergraduate students to receive training in genetics in 1921. Years later, she noted that few college students wanted to study genetics.
Barbara McClintock decided to study botany, the scientific study of plants, at Cornell University. She completed her undergraduate studies in 1923. McClintock decided to continue her education at Cornell. She completed the master’s degree in 1925. Two years later, she finished all her requirements for the doctorate degree.
McClintock stayed at Cornell after she completed her education. She taught students botany. The 1930s was not a good time to be a young scientist in the United States. The country was in the middle of the great economic depression. Millions of Americans were unemployed. Male scientists were offered jobs. But female geneticists were not much in demand.
An old friend from Cornell, Marcus Rhoades, invited McClintock to spend the summer of 1941 working at the Cold Spring Harbor Laboratory. It is a research center on Long Island, near New York City. McClintock started a temporary job with the genetics department. A short time later, she accepted a perpetual position in the laboratory and got continual incomes. This gave her the freedom to continue her research without repeatedly asking for financial aid.
By the 1970s, her discoveries had had an effect on everything from genetic engineering to cancer research. McClintock won the Nobel Prize for Physiology or Medicine in 1983 for her discovery of the ability of genes to change positions on chromosomes. She was the first American woman to win an unshared Nobel Prize.

2 . Rosie Dutton teaches a weekly class for 10- and 11-year-olds. During a recent class, Dutton used apples to brilliantly explain the effects of bullying.
Rosie Dutton started out by showing the class two perfect-looking apples. But unknown to the students, she had dropped one of the apples repeatedly on the floor. She picked up the dropped apple and began insulting (侮辱；损害) it.
“I started to tell the children how I disliked this apple, that I thought it was ugly and it was a horrible color,” Dutton wrote. “I told them that because I didn't like it, I didn't want them to like it either.”
They passed that apple around in a circle and the kids joined in on the insults. Then, Dutton took a completely different approach with the other apple.
“We then passed another apple around and started to say kind words to it,” the 31-year-old wrote.
She eventually cut both of them open to reveal that the apple that had been insulted was bruised (青肿的) inside. The apple that received praise wasn't.
“When people are bullied, especially children, they feel horrible inside and sometimes don't show or tell others how they are feeling,” Dutton wrote in her post. “If we hadn't cut that apple open, we would never have known how much pain we had caused it.”
“Unlike an apple, we have the ability to stop this from happening. We can teach children that it's not OK to say unkind things to each other,” the 31-year-old explained in her post. She later added, “More and more hurt and damage happens inside if nobody does anything to stop the bullying. Let's create a generation of kind, caring children.”

3 . Watson entered Mr Smith's office. The boss was a hard man. He fired people who didn't do well without giving them a second chance.
“Watson,” said Mr Smith, “this past year your department hasn't earned money. We're going to drop that department. It's finished. I'm sorry—but you'll have to go.” “But, sir—if I just had a little more time. For the moment I need the job to keep my son at Riverside School.”
“What's that!” said the boss. “Riverside! I didn't know you had a boy there. That's an expensive school for a man with your salary.”
“I know, sir. But he likes it so much! He's a star athlete and the best boxer in the school. The boys call him Champ there.”
The boss sat perfectly still for a long time—a faraway look in his eyes. Then, suddenly, he said, “We've got to close your department, Watson. But you'll take over a new job in another department. It means longer hours—maybe more pay. Now get out. You're here for life.”
Watson got out, with surprise on his face. Then the boss took a letter from the top drawer of his desk. It was Herbie's last letter from Riverside School—written a few days before he died. He had read it over and over again with sick pain. The letter read:
I can't say the boys here are any nicer to me than the others were. I guess it's the same everywhere when you're a cripple. But don't worry about me, Dad. They've got a good chemistry department here. And there's one boy here who is really great. He's a track star and boxing champ and just tops in chemistry.
The boys call him Champ. He made them stop throwing my books around. And he knocked a boy down who hit me. He is the best friend I ever had. Dad, when I grow up, I want to do something for Champ. Something big—that he won't even know about.
Your son,
Herbie

4 . “If you are cold, it will warm you; if you are too heated, it will cool you; if you are depressed, it will cheer you; if you are exhausted, it will calm you.” The poem best identifies the passion for tea in Britain. Outside of the United Kingdom, many people refer to afternoon tea as “high tea”. Afternoon tea, also known as low tea, is what most people think of when they hear “high tea”. It involves things like manners, lace (蕾丝) and light meals such as cookies and finger sandwiches. It is typically served in the midafternoon and it was traditionally served on low tables, hence its two names.
Afternoon tea was started in the mid1800s by the Duchess of Bedford. Around that time, kerosene (煤油) lamps were introduced into wealthier homes and eating a late dinner (around 8 or 9 p.m.) became fashionable. This increasingly late dinner was one of the only two meals each day, and the other was a midmorning one. The story goes that the Duchess found herself with a “sinking feeling”. This came from hunger during the long wait between meals. She decided to invite friends over for various snacks and tea. The idea of an afternoon tea gathering spread across high society and became a favorite pastime of females for leisure. Later, it spread to other social groups.
However, the British working population did not have afternoon tea. They had a meal about midday, and a meal after work, between five and seven o'clock. This meal was called “high tea” or just “tea”. Traditionally eaten early evening, high tea was a substantial(内容充实的) meal that combined delicious sweet food, such as cookies, cakes or tea bread, with heavy food, such as cheese on toast, cold meats and poached eggs on toast. This meal is now often replaced with a supper due to people eating their main meal in the evening rather than at midday.

5 . The idea of using a public bathroom with see through walls may sound like the stuff of nightmares. But a famous Japanese is hoping to change that view, using new technology to make restrooms in Tokyo parks more inviting.
“There are two things we worry about when entering a public restroom, especially those cated at a park,” according to architect Shigeru Ban’s firm. “The first is cleanliness, and the second is whether anyone is inside.”
The newly-invented transparent walls can turn off both of those worries, Ban says, by showing people what awaits them inside. After users enter the restroom and lock the door, the room’s walls turn a powdery paste) shade and are no longer see-through.
Ban’s are sure to make for great conversation among visitors to the park-and they’ll stand out even more after dark. “At night, the facility lights up the park like a beautiful lantern,” the architect’s website says.
The group is behind the Tokyo Toilet project, world-famous architects to create toilets “like you’ve never seen. The project’s eye catching toilets are part of a plan to put people ar ease when isiting a public bathroom. The project may seem silly, but the 16 architects who are reimagining public toilets are some of the brightest names in Japanese architecture. The list includes four Pritzker Prize winners-Ban, Toyo Ito, Tadao Ando and Fumihiko Maki-along with international stars such as Kengo Kuma and Sou Fujimoto. The fashion designer Nigo is also contributing.
Ban’s colorful public bathrooms opened to the public this month in two parks: Yoyogi Fukamachi Mini Park and Haru-no-Ogawa Community Park. Other bespoke commodes will be opening in coming months.

6 . There are those who save every takeaway container. There are others who throw away every takeaway container and later wish they hadn't clone so. Wouldn't it be great if these two people could do each other a favor and just swap （交换）?
Across the world, those with too much "junk”, and those who can't get enough of it, are exchanging and sharing their stuff online on a network called Freecycle. On Freecycle, people can swap with others who live within a few miles of them. All you have to do is list whatever you have to give away or whatever you're looking for. Take a quick visit to the website, and you can get your hands on a baby stroller, a dictionary, or a pair of shoes. Just sign up and make sure you turn up to collect your new-- or , rather , old—item.
“Freecycling" isn't just a trend, though. It's becoming the accepted way of doing things. If your child has grown up, what better way to deal with his or her stroller than to give it to another kid? And if you're moving house, your expensive necessities, even beds and cupboards, can just be freecycled.
Admittedly? a lot of the items carry warnings, such as “TV with remote control missing” or ^saucepan （no lid）”. And some listings are a bit bossy, too, as in “ladies' shoes — must be collected TONIGHT! !
It's also possible to get a bit addicted to Freecycle. A "bamboo cocktail bar"， a “cupboard with 20 very small drawers”, a huge pile of ^squares of cloth, great for craft projects! It all sounded so good to one of my flatmates that she became an example of a ^Freecycle addict”. But that didn't matter, of course. Everything she got could later be freecycled off again.

7 . “If music is the medicine of the soul, let it play on,” said a famous person. I think he said so probably because he had got some help from music. Music has some strange functions. Medical scientists have found that a person who feels stressed can actually listen to a certain kind of music and become relaxed.
Researchers said that since stress comes as a result of some events in life such as starting a new family, starting a new business and starting a new job, one can actually listen to good music and feel good because good music touches humans in a positive way. Music helps you forget these events that make you worried and remember the important events that once happened in your life.
Depression(抑郁症) is a disease caused by stress, smoking, social problems, etc. Depression is also caused by difficulties such as failure in business. Depression may bring us weakness, headaches and loss of concentration. Good music makes one remember happy moments or days. If you play music about love, it makes you feel like falling in love again though you may have had several upset experiences. And such good feelings make you healthy.
Anxiety is another health problem that can be controlled by music. Anxiety is one of the side effects of some major health problems such as liver cancer and breast cancer. Good music makes you feel relaxed and relieves the pain caused by these diseases and you will feel better. Good music also makes you sleep better, and you need to know that sleep puts your body in a healthy condition. Good sleep takes away the effects of stress, depression and anxiety from a person.
1. What do you know about music according to the famous person in Paragraph 1?| A．Music can treat many kinds of diseases. |

8 . Traveling to a foreign country can make you frightened if you don't know the local language.Mr.Thibault has a number of tips to help travelers manage in a destination when they don't speak the native tongue, based on his own experience.Here are a few of them.
Download a Language Translation App
Mr.Thibault tends to rely on Google Translate and suggests that travelers find an app that works for them.Ideally, find one that specializes in the language you need to translate especially if the language uses a character set you’re not familiar with, or have difficulty pronouncing.
Speak with Your Hands and Head
Pointing with your hands and nodding or shaking your head, Mr.Thibault said, are easy ways to communicate with locals in the country you’re in.“Gestures are all universally understood，” he said.
Learn a Few Key Words
Knowing basic words and phrases like "hello""thank you” and “I’m sorry，I don’t speak your language.Do you speak English?” is a must, Mr.Thibault said.Showing that you care enough to learn some of the language before you go, and at least enough to acknowledge that you don’t know more, is a form of respect and will make you go a long way to be liked by locals.
Work with a Local Travel Agent
If you feel particularly uncomfortable in the country you’re heading to, and you have to go anyway, relying on a local travel agent who knows both your and your destination's languages can be incredibly useful.
Hire a Local Tour Guide
A tour guide can help you get a better grasp of the local language and is a good person to practice words and phrases with.Whenever Mr.Thibault visits a new country, he books a sightseeing tour with a guide on the first day of his trip.“I use this day to learn about my destination and get familiar with the language,”he said.
1. In what situation should a language translation app be applied while traveling abroad?| A．When you have trouble pronouncing the words. |
| B．When you want to acknowledge your ignorance. |
| C．When you want to practice the local language. |
| D．When you feel uncomfortable in the country. |
| A．Downloading a language translation app. |
| B．Learning a few key words. |
| C．Using body language. |
| D．Working with a guide. |
| A．By speaking with your hands and head. |
| B．By learning a few key words. |
| C．By downloading a language translation app. |

9 . Some termite (白蚁) species have figured out how to enjoy the shelter of the huge complex nests that the insects build without contributing to their construction. They avoid the full anger of their builder hosts by being extremely easy-going.
Animals that live in the nests of another species without affecting them are known as inquilines. Inquiline termites are unique among termites in being unable to make their own nests. Instead, they live in the hallways built by another termite, Constrictotermes cyphergaster. Until now, it has been unclear how the two parties kept peaceful in such tight quarters because termites are typically very aggressive towards outsiders.
Helder Hugo at the University of Konstanz in Germany and his colleagues collected Constrictotermes cyphergaster’s nests in the Brazilian Cerrado and brought them into the laboratory. They then placed host and tenant (房客) termites in either open or narrow areas and used video to track and record the ways in which the two species reacted to each other.
Right from the start, the inquiline’ termites moved around less than their hosts and interacted little with them, even in the much narrower area. “Many times,” says Hugo, “when two unrelated groups are put together in a limited space—such as an experimental area—the outcome is conflict with losses from both sides.” But that didn’t happen here. Despite attacks from host termites, the tenant termites were obedient. Hosts would bite or attack the inquilines with strong chemicals, but their targets never responded in the same way, choosing to flee. Some ignored the hosts completely.
“We did not expect that they would never fight back,” says Hugo, noting that the inquilines are capable of protecting their own place with mouths. “By preventing conflict going worse, inquiline termites may considerably improve their chances of living together with their host termites peacefully.”
“Passiveness does not necessarily lead to defeat, but can be a very useful strategy, saving energy and resources,” she adds. “Nature may not always be red in tooth and claw, and aggression is not any more successful a strategy than ‘cowardice’ (儒弱).”

10 . 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.
