Richard Browning has been attracted by flight ever since his father took him into the hills to fly gliders (滑翔机). He has certainly been an adventurer. Richard took it upon himself to develop his own jet suit and began to experiment with some of his friends. He made quick progress. In 2017, he felt confident enough to start a company called Gravity Industries that could make jet suits. It took 15 months to develop the very first one.
Five very small jet engines are built into the jet suit. These are powered by kerosene (煤油). Two engines are located on the pilot’s arms and one is placed on the back. Each engine weighs less than two kilos and can produce22 kilos of thrust(推力).
The pilot is able to control the direction and speed of the flight. He does this by small movements of the arms which require hours of practice. One wrong move and you could end up falling to the ground.
Richard is not only in charge of his company; he is also the chief test pilot. He has spent hours and hours perfecting the correct moves to create a perfect flight. He was able to enter the Guinness Book of World Records in 2017 when he became the fastest man in a jet suit and flew at 51 kilometres per hour. Since then, he has presented his jet suit at 60 events in 20 different countries around the world. More recently, he flew alongside Brighton Pier on the south coast of England at 136 kilometres per hour!
The objective of Richard’s company has been to build a suit which members of the public can buy. The first went on sale in a department store in 2018 for f 340, 000. If you want to jet around your own hometown, it’s time to start saving—or to work for Richard Browning.

【推荐1】In mid-2019, an Indonesian design team submitted a plan to an international design competition for a new type of submarine (潜艇). It wasn't designed for military purposes or for exploring the ocean. The main purpose of this submarine was to create ice blocks to replace sea ice in the Polar Regions.
In the summer months of 2019, a massive heat wave shocked Europe and broke a number of high temperature records. As the hot air moved north over the Arctic, the ice sheet covering Greenland melted at an unexpected rate. Ice melt at the poles is normal in the summer months. Lost ice is often regained by refreezing in winter. But the fast melting rate could mean a permanent loss of polar ice, which would have global consequences.
Dealing with such a large-scale problem requires large-scale solutions. While many solutions look at reducing the greenhouse gases, few are aimed at repairing the effects of climate change. The ice-making submarine proposed to do just that.
The ice-making submarine's basic design involves forming a large hexagonal (六边形的) ice block of roughly 25 meters across and 5 meters thick. A large container in the submarine would be filled when submerged under water. Then the slow process of desalination (脱盐) and freezing would begin. After about a month, the submarine would discharge (卸下) the ice block and begin the process all over again. The overall vision would be to have multiple submarines working together, so that the hexagonal blocks could be pushed together to form a single large ice sheet.
The design was beautifully presented and won second place. However, the science behind the design came under criticism. One criticism was how the massive amounts of energy needed to desalinate and freeze the water would be provided. Another was that the amount of heat generated by the freezing process would result in a net warming effect. Additionally, the ice would be too thin to stay frozen for a significant amount of time. The designers couldn't sufficiently answer many of the scientific criticisms. Their inventive idea does, however, indicate the need for creative solutions in repairing the loss of polar ice.

【推荐2】Conventional chemical fertilizers (化肥) aren’t among the most eco-friendly substances in the world. Not only do they pollute the environment if they get into waterways, but they also reduce nutrients in the soil over time. What’s more, they’re relatively expensive.
Seeking a greener and more sustainable alternative, some farmers have started applying nitrogen-fixing bacteria (固氮细菌) to their crops. These bacteria absorb nitrogen gas from the atmosphere and turn it into ammonia in the soil. That ammonia provides the plants with nutrients, restores poor soil, and boosts the plants’ natural defenses against pest insects.
One problem with the bacteria, however, is the fact that they are very sensitive to heat and humidity (湿度). This means they don’t stand up well to being shipped out to farms from a central source.
With these drawbacks in mind, Asst. Prof. Ariel Furst and her colleagues at MIT have created a method of coating the bacteria in tiny “metal-phenol network” (MPN) shells (外壳). The shells contained organic compounds called phenols, which are generally regarded as safe by the Food and Drug Administration.
This new coating technology could make such bacteria more widely available than ever before. On one hand, these coatings don’t block the bacteria’s growth or functions. On the other hand, they do provide protection from heat and humidity. The coated bacteria can even be freeze-dried, then shipped and applied to crops.
Furst’s team created 12 different MPNs which comprised metals such as iron, manganese, aluminum and zinc, all of which are considered safe for use as food additives. When these MPNs were used on nitrogen-fixing bacteria, all of them were found to protect the bacteria from temperatures of up to 50℃ and from relative humidity of up to 48%.
Furst is now commercializing the technology through a company she founded, called Seia Bio. “When we think about developing technology, we need to intentionally design it to be inexpensive and accessible, and that’s what this technology is.” she said.

【推荐3】For most people, the thought of having to watch themselves work out is not an attractive one. Yet as any gym-goer knows, there are always some people who like to enjoy their reflection in the floor-length mirrors. It is perhaps these particular keep-fit lovers who are most excited about the latest trend in home exercise-smart fitness mirrors.
These are 180cm or so tall, high-tech mirrors that have a computer which is connected to the Internet, and also work as a video screen. The idea is that people contact an online trainer, who then appears in the mirror along with their reflection.
On the more advanced devices the mirror is equipped with cameras, speakers and numerous sensors (传感器) connected to AI, so the trainer can watch people’s movements, and provide improvements and changes. On the simpler mirrors the video and sound are just one-way- people can see and hear the trainer, but not the other way around. Lessons are typically not live; instead, people just get into a library of online workout videos.
But is there any actual advantage in being able to watch yourself work out? Colleen Logan, the US owner of both Nordic Track and ProForm, says, “Seeing themselves in the mirror allows the users to correct their form or position, so they get the best possible benefits of strength exercises and reduce mistakes that could lead to injuries”.
However, Dr Anthony Papathomas, a sports and fitness psychologist says there is value to this argument, but that he also has some concerns. He said,“How people who are not confident about their body image feel about the mirror gets me in a fret. It may be a problem for those new to exercise and looking to make a lifestyle change. Even for regular exercisers, there are many who experience body dysmorphia (变形) or eating disorders, and for them, seeing a reflection throughout their exercise might be troubling.”

【推荐1】Jack was 11 months old in the spring of 2015 when his parents, Erika and Christopher, recognized his development was not progressing as it should. The feeling was familiar to the couple. Just a few months earlier, Jack’s brother Chase, who is 16 months older, had been diagnosed with autism(自闭症) after he did not reach motion and language standards as expected.
Jack’s behaviors were similarly delayed, and his parents moved quickly to seek help. Today, Jack is 5 — he celebrated his birthday on May 13 — and he can speak in full sentences and read. After two years at a preschool that specializes in services for children with developmental disabilities, he will start kindergarten in the Smithtown school district in September. “Our family’s experience is a good example of the power and effectiveness of early intervention. The services our boys have received made all the difference,” the parents said.
According to scientists, autism can be detected at 18 months or younger, and by age 2 a diagnosis can be considered “very reliable.” The parents said they were happy with Chase’s success at the learning center, but still had concerns for Jack because he was not speaking. Developing social and communication skills can be among the greatest challenge for individuals with autism, even if they are able to say a few words early on. “We didn’t know if he was ever going to talk,” Erika said. “That was my biggest fear. We just didn’t know.”
Looking ahead, the parents are cautiously optimistic about Jack’s next educational move. He doesn’t handle change well, they said, and he likes to know his routine. Still, they expressed confidence that his time at the learning center has given him the skills he needs to be successful.
1. How did Jack’s parents know he suffered from autism?A.They found the baby clever. | B.They judged by their experience. |
C.They found he didn’t develop. | D.They checked on him in the hospital. |
A.It made no difference to the babies. | B.It benefitted the babies greatly. |
C.It got their babies more disabled. | D.It helped their babies speak fluently. |
A.Autism can be confirmed at 18 months old. |
B.Jack’s parents were confident about his motor skills. |

【推荐2】Washington is home to lots of trees—it is the Evergreen State, after all—and lots of fireplaces and wood-burning stoves too. But what if you lived there and couldn't chop (劈) wood or couldn't afford to pay someone to do it? Luckily, Shane McDaniel and his twin sons are happy to lend an ax. The three men chop truckloads of wood—then donate it to those in need.
The idea started as a father-son bonding project. "I had to cut wood with my dad. He just loved doing it," said Shane. He wanted to pass along that feeling, so he and the twins spent the summer chopping wood. The result was a great wall of wood piled up around their house, which is worth about $10,000.
It was too much for the Mc-Daniels to use themselves, and when the weather turned cold that November, Shane started thinking of others. He posted on the Internet: "IF YOU ARE IN NEED OF FIREWOOD AND CANNOT AFFORD IT, PLEASE CONTACT ME! ... If you know someone who NEEDS WOOD, and they're looking at a cold house, please help us help them. Please help us make sure NO ONE GOES COLD IN OUR HOOD."
The response was immediate. One man offered to donate a wood-burning furnace. Others raced over to Norm's, the mini-mart Shane owns, with more wood for the pile.
Single mom Katelyn Ticer and her four-year-old daughter rely on a wood-burning stove as their only source of heat, so it was a relief to receive a truckload of firewood from the McDaniels before the holidays. “To get that much wood brought me to tears,” she said. “So much stress and anxiety is off my shoulders. I couldn't be more thankful.”
However, not every recipient is grateful, and some aren't even friendly. But Shane is OK with that. "Giving is the reward,” he says. “It has nothing to do with how well it's received; it's about how much it's needed.”
1. Why did Shane start chopping wood?A.He wanted to teach his sons a living skill. |
B.He wanted to kill the boring summer time. |
C.He was inspired by a childhood experience. |
D.He planned to make more money through this. |

【推荐3】It's a classroom; but instead of being told to sit quietly and listen, you are encouraged to stand up, jump around, imagine and act out it's a class full of laughter and applause(掌声), emotion and energy. Welcome to drama class, one of my favorite classes at high school.
In drama class we used to play a lot of“ drama games. We would improvise(即兴表演), mime(模仿) and above all use our imaginations.
My favorite game was called "Spotto". One person stood at the front of the class and performed a scene, completely out of their imagination. When one audience member yelled "Spotto!", the performer had to freeze. Then the person who had yelled Spotto had to get up and improvise a new scenario (剧情)based on the position the first performer froze in. This went on as more and more people were added to the scene.
Eventually the entire class would have joined the scene. Then the performers would start to leave in reverse(颠倒的)order. The first performer had to have a good memory to remember all the other scenes.
It was a lot of fun, and a good test of everyone's imagination to see what they would come up with.
Drama class at my school often involved a big performance at the end of the semester as well. We would work on a production throughout the semester and put on a show for our parents and the school community.
It was a great experience to perform on stage in front of a large audience. Drama class can help shy children to come out of their shells. It helped me become more confident and developed my public speaking skills. Drama class is also a great place to express yourself, and a way for children to use up some of their energy.

【推荐1】My family and I never talked about school as the ticket to a future. I was in the classrooms, but I wasn’t there to learn to write, read or even speak. When it was my turn to read, I wanted to hide. I was 13 years old, but I already hated being who I was.
I had an English teacher, Mr. Creech, who knew I couldn’t read. In one of my first lessons the teacher said that anyone who had a reading age below six had to stand up. I felt so embarrassed. But at the same time, it made me realize that I needed to change the situation. I was determined it wouldn’t happen again. Later that day, Mr. Creech encouraged me and promised he would try his best to help me learn to read. From then on, I never gave up practicing reading.
Now I was 41 years old. One day, I planned to fly back to Texas to visit my friends and family. On my way from the airport, I saw Mr. Creech buying himself a drink. I rushed over and reached into my pocket to pay for him.”Do I know you?”he asked.”Yes, sir, you do know me,”I answered excitedly.”My name is Anthony Hamilton. You taught me English.”The look on his face told me that he remembered the boy he’d once encouraged.
“I’m so glad I had a chance to see you,”I said.”And Mr. Creech, I have great news to share.”I told him I had learned to read. But that wasn’t all. I had become a published author and an active speaker.”The next time you get another Anthony Hamilton in your classroom, please encourage him to read as well.”I added.
The experts say what once worried me has a name: dyslexia(诵读困难症). But I can tell you it was a lack of desire for education.

【推荐2】The sun was rising as we drove across the Minnesota state line to New York for my new Ph.D. program. The move was good for me professionally, but I worried about my husband and daughters. I also feared that I wouldn’t be able to give my kids the childhood they deserved.
Anne, our first daughter, came into the world when I was a junior majoring in biology in college. It was challenging to balance classes, work schedules, and being a mom. But I got it through, finding moments of delight along the way. On the nights when I was at home, I’d read my class notes out loud with my daughter. She’d respond by asking questions, such as “Mom, what are bacteria?” It helped us both learn.
After I graduated, I knew that I would need a Ph.D. to land the kind of job I wanted. I arrived in New York feeling more than the usual new⁃grad⁃student anxiety. I also suffered from a more personal fear that I was selfish—my decision to invigorate my career was going to have long⁃term negative impacts on my kids.
Over the past year, though, I’ve started to let go of some of the worry. I’ve realized that not only have we adapted to our new situation, but things are getting better. My husband has landed a job that he is happy with. Anne has dreamed of becoming a marine biologist. Recently, while driving past the cancer institute I work at, Anne said, “Thinking about people having cancer is so sad, but I feel better knowing that you are researching it to help.”
Navigating academia as a young mother is hard, but it’s also rewarding. My kids are learning to look at the world through the lens of science, and watching their mom succeed inspires them. I look forward to seeing them follow in my footsteps, whatever path they choose.

【推荐3】When I was three years old, I couldn’t speak. It was a strange reality that none of the doctors I visited could understand.
One day, I was shadowing (跟随) my mother. She found herself looking in a mirror, and through it our eyes met. She began to speak to me through the reflection, and I slowly began to mimic (模仿) her mouth’s movements until I formed a word.
It turned out I’m deaf in my left ear, and have a slight problem in my right. Being hard of hearing has been difficult, but I’ve never lived in a state of self-hating sorrow. Imagine being able to shut out all sound as you lay your head down to sleep by simply rolling over onto one side. That’s my reality when I sleep on my “good ear”, and it makes me feel like a superhero sometimes.
People call my deaf side my “bad ear”, but when I wear my hearing aid, I have access to a range of features that some other deaf people don’t. In cinemas, for example, with one click of a button I can enjoy a whole film as though it were whispered to me from the mouths of the actors.
Owning a hearing aid hasn’t always felt good, however. On the first day I got my aid, when I was eight, I took it to school for show-and-tell. As I explained how it worked to my classmates, a boy yelled out, “Aren’t those for old men?” At that moment, I felt different. It took a long time for me to get over that sense of being so unlike my peers.
But it’s not just school kids who can make us deaf and hard-of-hearing people feel like burdens. Every video on social media that lacks subtitles (字幕), for example, means an entire community of deaf people is unable to enjoy it. Completely deaf people are excluded from enjoying many movies too, as subtitles in cinemas are almost impossible to find.
And with hearing aids costing around $2,500 each, it can be hard for many people to afford to be able to listen to the things that others take for granted. As for me, I can listen to music, enjoy films, and catch conversations—I’m lucky. I’m deaf, but I can still hear everything. I’ve been blessed with wonderful life experiences, and I am human. And when it comes to sleeping, I’m even superhuman.
