1 . Many people, including some successful men, wear the same clothing daily to focus their decision-making energy on more important things.
Available online or from various shops, it allows everyone to adopt the latest fashion trends instantly. Though that sounds like a win-win for all, the rapid change in styles and the affordable prices result in impulse (冲动) purchases, many of which are thrown away after being worn just once or twice.
Julia's idea for the “One Outfit (服装), 100 Days” began as a comment she made to her husband during the summer.
A.Julia is also tired of making decisions on small things. |
B.The experiment has aroused curiosity of many students. |
C.Julia's “One Outfit, 100 Days” challenge, however, has a selfless aim. |
D.Thanks to Julia's idea, the whole school began to follow her challenge. |
E.She hopes more people will learn from her and apply the 3Rs to their life. |
F.Over 21 billion pounds of cloth ends up being waste yearly in the US alone. |

2 . With the development of our society, cellphones have become a common part in our lives. Have you ever run into a careless cellphone user in the street? Maybe they were busy talking, texting or checking updates on WeChat without looking at what was going on around them. As the number of this new "species" of human has kept rising, they have been given a new name—phubbers (低头族).
Recently a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cellphone while letting his patient die. A pretty woman takes a selfie (自拍) in front of a car accident site. And a father loses his child without knowing about it while using his mobile phone. A chain of similar events will finally lead to the destruction(毁灭) of the world.
Although the ending of the film sounds unrealistic, the damage phubbing can bring is real. Your health is the first to bear the effect and the result of it. "Always bending your head to check your cellphone could damage your neck," Guangming Daily quoted doctors' words. "The neck is like a rope that breaks after long-term stretching." Also, staring at cellphones for a long time will damage your eyesight gradually, according to the report.
But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. When getting together with family or friends, many people prefer to play their cellphones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported.
It can also cost your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cellphones in broad daylight.

3 . Some colors that people see late at night could cause signs of the condition mental health experts call clinical depression. That was the finding of a study that builds on earlier study findings. They show that individuals who live or work in low levels of light overnight can develop clinical depression.
Doctors use the words “clinical depression” to describe severe form of depression. Signs may include loss of interest or pleasure in most activities, low energy levels and thoughts of death or suicide.
In the new study, American investigators designed an experiment that exposed hamsters to different colors. The animals were separated into 4 groups. One group of hamsters was kept in the dark during their nighttime period. Another group was placed in blue light, a third group slept in white light. While a fourth was put in red light. After four weeks, the researchers noted how much sugary water the hamsters drank. They found that the more depressed animals drank the less amount of water.
Randy Nelson, who heads the Department of Neuroscience at Ohio State University, says animals that slept in blue and white light appeared to be the most depressed. “What we saw is these animals didn’t show any sleep disruptions at all but they did have messed up circadian clock genes (生物钟基因)and they did show sign of depression whereas if they were in the pale red light, they did not.” He says there’s a lot of blue in white light, which explains why the blue light and white light hamsters appear to be more depressed than the hamsters that see red light or darkness.
Mr Nelson has suggestions for people who work late at night, or those who like to stay up late.
“My recommendation is if you are just living a typical mostly active life during the day, mostly inactive at night, you need to limit exposure to TVs which are quite bluish in the light they give off and computer screens and things like that. You can get filtered glass, you can get filters (过滤器) on your computer screen and filters on your eReaders to put it more in the reddish light.”

4 . This year’s Olympic Games have been closed to most spectators (观众) because of COVID-19, but the eyes of the world are still on the athletes thanks to five extra cameras—the first step in a 3D tracking system that supplies spectators with instant insights into each step of a race.
The tracking system being used in Tokyo, an Intel product called 3DAT, feeds live footage (影像) into the cloud. There, an artificial intelligence program uses deep learning to analyze an athlete’s movements and identifies key performance characteristics such as top speed and slowdown. The system shares that information with viewers by displaying the action of slow-motion, highlighting key moments. The whole process, from capturing the footage to broadcasting the analysis, takes less than 30 seconds.
“It’s like having your own personal commentator point things out to you in the race,” says Jonathan Lee, director of the Olympic technology group.
To train their Olympic AI via machine learning, Lee and his team had to capture as much footage of best athletes as they could. They needed recordings of human bodies performing specific moves, but the preexisting footage shows average people in motion, Lee says. “People aren’t usually seven feet in the air,” he notes, but world-class high jumpers reach such heights regularly.
In the footage, a team at Intel record every part of the body—eyes, nose, shoulders, and more. Once those key points were identified, the model began connecting them in three dimensions (维度) until it had a simplified performance of an athlete’s form. Lee thinks the AI could help everyone from Olympians to average gymgoers correct their form and track changes in their moves that may indicate upcoming injury. “Long-term, what this technology will do is help improve an athlete’s performance by giving them more information,” two-time Olympic champion Ashton Eaton said.

You’ve been around forever. I can remember all the pain you’ve caused for me.
Do you remember the night you almost took my father’s life? I do. He loves you. Sometimes I think he loves you more than he loves me. He’s addicted to you, to the way you promise to rid him of his problems only to cause more of them. You just sat back and laughed as his car went spinning through the street, crashing into two other cars. He wasn’t the only one hurt by you that night.
Do you remember the night of my first high school party? You were there. My friends were intrigued by you. They treated you as if they were never going to see you again, drinking all of you that they could. I spent two hours that night helping my friends who had fallen completely. “I’m so embarrassed,” they said as I held their hair back so that they could vomit(呕吐). “I’m sorry,” they said when I called taxis for them, walking them out and paying the driver in advance. “This won’t happen again,” they said as they were sent to the hospital to have their stomachs pumped. Two 15-year-old girls slept in hospital beds that night thanks to you.
Do you remember the night when you took advantage of my 17-year-old neighbor who had to drive to pick up his sister from her dance lessons? Do you know how we all felt when he hit another car and killed the two people in the other car? He died the next morning too. His sister walked home from her dance lesson, and passed police cars and a crowd of people gathering on the sidewalk just two blocks away from the dance studio. She didn’t realize her brother was in the midst of it all. She never saw him again. And it’s all your fault.
I wish you’d walk out of my life forever. I don’t want anything to do with you. Look at all the pain you’ve caused. Sure, you’ve made people happy too from time to time. But the damage you’ve caused in the lives of millions is inexcusable. Stop luring(引诱)in the people I love. Stop hurting me, please.
Sincerely,
Anonymous

8 . The other day, my sister and I were sitting in the restaurant, trying to have a conversation, but her children, four-year-old Willow and seven-year-old Luca, would not stop fighting. The arguments——over a fork, or who had more water in a glass--never stopped.
Then my sister reached into her handbag, produced two shiny iPads, and handed one to each child. Suddenly, the two were quiet. They sat playing games and watching videos, and we continued with our conversation.
After our meal, as my sister stuffed the iPads back into her bag, she said, “I don’t want to give them the iPads at the dinner table, but if they keep them occupied for an hour so we can eat in peace, I often just hand them over. I am afraid that it’s bad for them. I do worry that it makes them think it’s OK to use electronics at the dinner table in the future.”
Dr. Gary Small, director of the Longevity Center at the University of California, Los Angeles says that the brain is highly sensitive to stimuli(刺激物), like iPads and smartphone screen, and if people spend too much time on one technology, and less time interacting(互动)with people like parents at the dinner table, that could prevent the development of certain communication skills.
“Conversations with each other are the way children learn to have conversations with themselves, and learn how to be alone,” said Sherry Turkle, a professor of science, technology and society at the Massachusetts Institute of Technology. She fears that children who do not learn real interactions, which often have imperfections, will come to know a world where perfect, shiny screens give them a false sense of intimacy(亲密) without risk. However, they need to be able to gather themselves and know who they are. So someday they can form a relationship with another person without a panic of being alone. “If you don’t teach your children to be alone, they will only know how to be lonely,” she said.

9 . Mr Jason has taught math in a remote rural area for ten years. Last year, he was awarded (奖励) $2,000 as “The Amazing Teacher”. People thought he would move with his parents to a nice house in the city. But he surprised then all. When students came back from their holiday, they found the chairs, desks and projectors (投影仪) were all replaced. Even the walls of the classroom were painted white.
As a teacher, Mr Jason not only focuses on students’ studies, but also helps students overcome the difficulties in life. In the rural area, most families are poor and some students often dropped out of school. Mr Jason always tries to help then out.
When interviewed, he said, “When I was in middle school, a Mr Smith helped me until I graduated from university. I attempted many times to find him after graduation, but failed. I thought maybe what he most wished was not my thankfulness but another Mr Smith. So I am here.”
“Mr Jason is the best teacher I have ever had. Without his help, my whole life would end in the village. When I was in Senior Two, my family couldn’t afford my tuition (学费) so I stayed at home. At that time, I felt hopeless. It was Mr Jason who asked my parents to send me back to school. Luckily, I was admitted into my ideal university finally,” said Julia, a fresh college student. “Now, I believe the road ahead is promising.”
Mr Jason’s goodwill touches many people. When the activity “The Amazing Teacher” was launched, someone posted his story on the Internet. And it soon spread over.
Later, Mr Jason wrote: I just have done what a teacher should do. I hope people could pay attention to those children in need and help them realize their dreams.
1. What did Mr Jason do with the money he was awarded?A.He settled down with his family in a big city. |

10 . Since the beginning of my scientific training, I was encouraged to seek multiple mentors (导师) to help me find my way. With many efforts, I became comfortable, confident, and strategic in building my network of mentors.
Cast a wide net.
Sending cold contacts was scary, so I focused on the thrill of emailing people who had some of the coolest jobs I'd ever heard of. If I was inspired by someone's work, I emailed. If
I loved the way they ran their lab, I emailed. If I was interested in learning more about their company, I emailed.
As a grad student, I met someone at a conference who I hoped would be a future mentor—and followed up with a five-paragraph email. Their reply was simple, “I cannot respond to this. Too long.” Over the years, I learned to clearly include the what, the ask, and the when —for example, a 30-minute meeting to talk about X, offering three or four specific times. A clear, concise email encourages a quick, positive response.
Consider the context (情景).
In graduate school, I asked a senior faculty member to serve as my departmental adviser.
Come prepared.
A.Get to the point. |
B.Here's what I have learned. |
C.Prepare for negative responses. |
D.My one strength was preparation. |
E.My mentors offered many suggestions to me. |
F.Though a few people failed to respond, many did. |
G.The response was a direct without any explanation, and I was left confused. |
