Not all memories are sweet. Some people spend all their lives trying to forget bad experiences. Different accidents can leave people with terrible wounds both in body and mind. Often they recall these experiences in their awful dreams.
Now American researchers think they are close to developing a kind of medicine, which will help people forget bad memories. The medicine is designed to be taken soon after a scary experience. They hope it might cut down, or possibly clean up, the effect ( 影 响 ) of painful memories. In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals(释放化学物质)that make memories remain in the brain. So far the research has suggested that only the effects of memories in mind may be cut down, not that the memories are cleaned up.
The research has caused a great deal of argument. Some think it is a bad idea, while others support it.
Supporters say it could lead to a kind of medicine that prevent or treat soldiers’ troubling memories after war. They say that there are many people who suffer from terrible memories.
“Some memories can destroy people’s lives. They come back to you when you don’t want to have them in a daydream or awful dreams at night. They usually come with very painful feelings,” said Roger Pitman, a professor at Harvard Medical School. “This could cut down lots of that suffering.”
But those who are against the research say changing memories is very dangerous because memories make us different from others. They also help us all avoid the mistakes of the past.
“All of us can think of bad events in our lives that were terrible at the time but make us who we are. I’m not sure if I want to forget those feelings.” said Rebecca Dresser, a medical scientist.

When I was 12, I would, on some Saturdays, go to my father’s store to help out. After helping set up the outside clothing display, for the rest of the day, I’d watch to make sure no one stole anything. When I noticed someone looking unusual or strange, I would look the person in the eye, smile and say, “May I help you?” Usually that worked, but sometimes, someone would run off with something. The first time, I ran after the thief but my father shouted, “Martin, stop! There is no need to do that.” It’s true that safety is more important than money.
After 10 years of hard work, he saved up enough money to buy his first car, a cheap one—he wouldn’t buy one until he could afford to pay for it without borrowing money. I learned: buy only what you can afford. Buying necessary food and clothing won’t make us go in debt(债务). The unnecessary things won’t give us happiness, which comes from achievement only.

【推荐3】My vacation with Grandma and Grandpa was great!They used to live with us in New York,but they moved to Arizona when I was five.They are Native American,and Arizona has always been their home.Dad usually visits them, but not this summer!Dad is sending me to stay with them for a two-week adventure.
This was my first time to travel alone.On the airplane,I studied the picture that Grandma had sent me.It was a picture of Walpi, an old Hopi village where Grandma and Grandpa live.The village is on top of a tall rock hill.It looked steep, and I wasn't sure I could climb that high.I also wondered if Grandma and Grandpa would act more differently in this village than they had in our apartment in New York.Would I be a stranger there?
Grandpa met me at the airport.He looked the same!We picked up my suitcase and took it to Grandpa's truck.As we drove away from the city, I stared at the beauty of the desert.An eagle flew above us.Soon we headed up the path to Walpi.Grandpa parked the truck on the edge of the hill.I looked down.We were so high up, I felt like a bird!He took me to some stairs that led to a door of the building.Ladders were used to get to other rows of doors on the second and third floors.
Grandma was waiting for us."Joe,this is called a‘pueblo'.The buildings are made from stones and baked clay,” she explained. “We live on the first floor, and other people live above us."
Grandma and Grandpa's rooms felt cool after standing under the hot Arizona sun.Grandma said that the stones kept the rooms cool.Her handwoven(手织的)rugs covered the walls.After eating beans and cornbread that Grandpa cooked on the stone fireplace, we took a walk outside. We visited the"kiva", which is a large room where the Hopi go for special events.
I really liked meeting the Hopi people.One man helped me make a clay vase to take home to Mom.The children included me in their ball games and foot races.Sometimes I helped Grandpa and his friends work in the fields.One afternoon a woman showed me how to weave a basket from grasses.The whole time I felt as if I were part of a big family in our secret village in the sky.It was hard to leave my grandparents when my two weeks were over.I could have lived in Walpi forever!

【推荐2】By drawing patterns (图案) on the surface of a cup of tea, chabaixi, an ancient Chinese tea trick displayed in a recent TV drama, has become popular for its clear similarity with modern latte art (咖啡拉花艺术). However, ten years ago, this special technique was close to disappearing completely. Zhang Zhifeng, a practitioner of chabaixi, found scenes of chabaixi in the drama aroused great interest among ordinary people.
Chabaixi can create endless patterns such as bamboos and mountains or even calligraphy. There are over a dozen steps, from grinding (碾碎) tea for fine powder, to pouring boiled water, stirring the mixture for thick froth (泡沫), and finally drawing the patterns. It is different from making latte because people use clear water as the object to put into the cup instead of milk. But when the water touches the surface of whipped (搅打起泡沫的) tea, it turns into a white color and disappears in 20 minutes. The process before the drawing is known as the tea-making technique, diancha. The quality of diancha is important to whether patterns can be successfully produced later.
“Chabaixi is one of the countless forms of tea-making techniques in China. The importance of chabaixi is not only that this technique is unique in the world, but also it gives us a window into people’s lifestyle in the Song Dynasty, a period when leisure activities in some ways resemble what we have now.” Zhang said.
Before chabaixi was discovered by TY audiences, the technique was listed as part of China Intangible Cultural Heritage in 2017, after it was recovered by Zhang Zhifeng. He started researching the origins of chabaixi in the 1980s and brought the technique back in 2009 after decades of trials and practice. Zhang spent nearly 30 years studying and researching the origins and making of tea but for him it was all worthwhile.
“This technique is key to the tea culture of the Song Dynasty, and it would be a shame to let it fade. This technique must be passed on to the next generations so they can understand its history.” Zhang said.

①Japan’s population is rapidly aging, with 28 percent of its people aged 65 or older. This means there aren’t enough young people doing jobs that need physical strength (力量) like building things and farming.
②To encourage older people to work on, technology companies in Japan have developed special suits called exoskeleton (外骨骼). These suits can make it easier to lift and carry heavy objects.
③“We have no choice, elderly people need to stay in the workplace,” says Daigo Orihara at Innophys. This company has made a suit called the Every Muscle Suit. It’s light, weighing less than 4 kg. It doesn’t need any batteries (电池) or motors (发动机). When users put it on like a backpack, they pump (抽气) air into it 30 times with a hand pump. Then, the suit can help them lift up to 25 kg easily. The suit costs about 1000 pounds and is used by food companies to help worker lift big boxes, by old people’s homes to help workers lift people in and out of bed, as well as by food factories and building companies.
④Another company, Panasonic, is also developing different exoskeleton suits. Its most important one—the Atoun Model Y—costs 4200 pounds. It uses motors instead of air to work and can last for 8 hours. It weighs 4.5 kg and can help users lift up to 10 kg.
⑤Similarly, Japanese company JTEKT, part of the Toyota group, also began selling an exoskeleton. It’s used to help older workers and also runs on a motor.
⑥As Japan is facing the problems of fewer and fewer workers, they may need to raise the age when people stop working. This means there will be even more need for exoskeleton to help older people keep working.
1. Why do Japanese technology companies develop exoskeleton?A.To take the place of humans with machines. |
B.To compete with other countries in technology. |
C.To encourage older people to stay in jobs for longer. |
D.To help young workers move heavy objects more easily. |

In a small room, Zhang Man is describing the products (产品) to viewers who are watching her live streaming. She sells more than 100,000 pairs of shoes in just ten minutes.
Mi Sitian is a new mom from Lanzhou, the capital of Gansu Province. She is a die–hard fan of streaming shopping. For her, it is a time-saving and easy way of shopping. “I can hardly find the time to go shopping after having a baby,” she said, “I only have some free time at night to watch live streaming and shop online.” Also, live streaming shopping makes it possible for her to communicate with the sellers face-to-face. “It’s just like shopping in the real stores.” she said.
For sellers, live streaming helps them attract (吸引) more buyers online and sell more products. Even the Chinese government sees it as a way to help farmers out of poverty (贫困), Shandong Province. She attracted 90,000 fans and sold more than 1.1 million yuan of fruit in a few months through live streaming.

【推荐2】It's no secret that laughter works wonders for us. And much research has been carried out into the good that laughter can do for our general health and well-being. It has been found to release endorphins (释放安多芬), our bodies’natural“feel-good"chemicals, into our blood. But as we grow older, we are more likely to find fewer things funny. A child will laugh on average 300 times a day. By the time we reach adulthood, this number is around 20. But what's behind this? One theory(理论) suggests that it's not a problem of us losing our sense of humor but rather, as we grow older, we're socially conditioned to take things a bit more seriously.
Laughter is very much something we do with others. Studies have shown that we are 30 times more likely to find something funny when we are with others than when we are by ourselves. But to laugh with others, we do need to feel a connection to them. We need to feel comfortable in their company. That's why it can be difficult to laugh in the presence of strangers. Laughter is also very contagious and one person's laugh can spread quickly throughout a group of people. But often what makes us join in is the fear of standing out and being different. We laugh, even if we don' t really get the joke, especially in groups controlled by a powerful person. When the head teacher tells a joke, for example, you laugh, even though later you might wonder if the joke was really that funny at all.
There are many different reasons why we laugh. Here are three widely accepted theories:
The Incongruity Theory: It's often the unexpected that makes us laugh. When things that we are familiar with suddenly take a turn into the unknown, our expectations are challenged and that often results in laughter.
The Superiority Theory: We often find the mistakes and misfortunes of others funny. This would explain the popularity of online videos showing pranks (恶作剧).
The Relief Theory:Laugh offers light relief. It explains why there are so many jokes about the darker things in life. By being able to laugh at them, we are able to face them more easily.
1. According to the theory in Paragraph 1, why do we laugh less as we grow older?A.There are fewer funny things. |
B.We take things more seriously. |
C.Our body releases less endorphins. |
D.We gradually lose our sense of humor. |
A.More funny things happen when we are with others. |

【推荐3】All over the world, thousands of animals are used for wildlife tourism. People travel to watch monkey shows, hug baby tigers and swim with dolphins. It might look like fun, but there are reports that animals are hurt now and again. The World Animal Protection (WAP) says that up to 550,000 wild animals are exposed (暴露) to ill treatment around the world. In Cambodia, for example, it’s been reported that elephants have died after carrying tourists for long in hot weather. This is getting attention—over 100 travel companies have promised that they will no longer open up such places. However, some people argue that animal tourism isn’t always as bad as it seems. So what do you think?
Group Yes
◇Animals weren’t put on this planet for enjoyment. They should be free to live as they choose.
◇The way animals are treated is often cruel (残忍的) and causes much pain. Even if treated well, they cannot act in the same way as they would in the wild.
◇We don’t need wildlife tourism. We can see animals close up in their natural home in TV programs. There’s no need to disturb (打扰) them in real life.
Group No
◇It is enjoyable and educational for people to communicate with the wonderful animals. The more people know about them, the more they want to protect them.
◇Wildlife tourism brings money to poor areas and may be the only way for some people to make a living.
◇Not all animals are treated badly. Some endangered animals are under the protection of programs that look after rare species (稀有物种).

【推荐3】When Einstein was 16, he always played with a group of mischievous kids. Because he was so busy playing, he didn't study enough and failed his final exam.
One morning, when Einstein was holding a fishing rod and was about to go fishing with his friends, his father stopped him and said calmly, "Einstein, you're so fond of playing all day that you failed your exam. I'm worried about your future."
"What are you worrying about? Jack and Robert also failed, but don't they still get to go fishing?"
"My boy, you can't think like that," his dad said. "There is a fable(寓言故事)that people tell in our hometown. Listen to it now."
"There were two cats playing on a roof. One cat got caught off guard and fell down the chimney(烟囱)while holding the other cat. When the two cats climbed out of the chimney, one of the cats had soot(烟灰)on his face, while the other cat's face was clean. Seeing the soot-faced cat, the clean cat thought its face must be dirty, so it quickly ran to the riverside and washed its face. The soot-faced cat saw the clean-faced cat and thought its face was also clean, so it just swaggered down the street."
"Einstein, no one can be your `mirror'. You have to think for yourself. If you take your cues from others, you will never learn."
Hearing this, Einstein laid down his fishing rod and returned to his room. He decided to pay more attention to his studies and less attention to what his friends were doing. This allowed him to be successful.
