1 . China’s new bullet train is now the world’s fastest land vehicle (交通工具) China Rail-way Rolling Stock Corporation showed the production version of its magnetic levitation (磁悬浮) bullet train in Qingdao on Tuesday. State media says the train has a top speed of 373 mph. That speed doesn’t just make it the fastest train in the world, but makes it the fastest land vehicle. The bullet train is able to travel at such high speeds because of magnetic levitation. The technology uses electro-magnetic force to levitate the body of the vehicle less than two inches from the rails and drive it forward along the tracks. By riding on a cushion of air, friction (摩擦力) is completely reduced, allowing it to travel faster than traditional trains where wheels and rails are constantly in contact. Although China has made use of the technology for a couple decades now, it’s only ever been used at very limited areas.
China Railway says its bullet train will greatly help cut down travel time. At top speedy the vehicle will be able to complete the 754-mile trip between Beijing and Shanghai in just two and a half hours. That same trip takes just over three hours by plane, five and a half hours by current high-speed rail options or 12 hours by car. That could make the train an especially attractive travel option for business travelers in the country. It’s unclear when the new bullet train will go into operation. The vehicle that the company showed off on Tuesday is the finished article.
Of course, the train’s record might not stand for long. The Central Japan Railway Company is testing a maglev train. It will be able to top out at 375 mph, according to New Atlas. But that isn’t expected to be shown in public until 2027 at the earliest. That gives China Railway Rolling Stock Corporation plenty of time to refine and upgrade its bullet train and push its top speed even higher.

7 . Movies about the future often show people travelling around in flying cars. Last Tuesday, that vision came a step closer to reality for a Japanese company called SkyDrive, as it showed off its new flying car, the SD-03, in action. The small car flew around for four minutes, staying about 1-2 meters off the ground.
The SD-03 is powered by batteries and has 8 motors, which lift it straight off the ground. What made this test flight special was that a pilot was on board. Toraohiro Fukuzawa, who leads SkyDrive,said, “Of the world’s over 100 flying car projects, only a handful have succeeded with a person on board.”
Many groups worldwide are working to develop flying cars. Some governments, including Japan’s, are supporting the idea, hoping that in the future, flying cars will be useful for short trips like taxi rides in cities. Flying cars could also help reach places that can’t be reached by road.
What happens when a motor fails? If flying cars are crossing a city, an accident could hurt not just people in the car, but people on the ground, too. That’s why the SD-03 has eight motors—as backups.
Some people believe flying cars reduce traffic jams. But new systems will be needed to help control traffic in the air. With many cars flying around, these systems would be too complicated to be managed in real time by humans. Besides, flying cars are expensive. When it’s ready, SkyDrive’s flying car is expected to sell for between $300,000 and $500,000.
However, people who believe in flying cars point out that cars and airplanes faced challenges at first, too. With time, many of the big problems were solved. By 2050, Mr. Fukuzawa hopes people will be able to fly anywhere inside Tokyo in just 10 minutes. “I think flying cars will become normal in the near future.” he says.

9 . The e-bike industry is exploding around the world as people adopt the idea of an environmentally-friendly alternative for the daily trips and a way to enjoy the outdoors. Creative minds are introducing e-bike innovations like creative new body styles. Evie Bee, a woodworker, model maker and university student, has combined her passions into a unique and beautiful wooden e-bike she calls Electraply.
The design was inspired by Bee’s love for the motorcycles of the past and the desire to honour and continue this design classic through a modern interpretation.
Electraply is composed primarily of materials of a sustainably sourced tree-poplar ply, which is the inspiration for the name. The use of wood threatened to make the bike too heavy, but Bee used poplar ply for the central frame (框架) so it was no heavier than an ordinary e-bike.
For the original bike, Bee collected the forks from an old jump bike. The decision resulted in the use of V-brakes (刹车) in the design. She says it’s not ideal but works for now, admitting, “The forks shall certainly be the first thing I upgrade once I have the money.” There are safety features to balance the system; the front brake is wired to the motor, causing it to turn off when the brakes are pressed.
Unlike most e-bikes, Bee didn’t try to hide the battery. In fact, she put it front and center. She explained, “The bike design was inspired by motorbikes, which have their gas tanks (油箱) visible. I wanted to carry this through into my own design, but change the gas tank for a battery!”
Bee is currently working on developing a Kickstarter campaign for Electraply with hopes of mass-producing and marketing it at some point. For those interested in working from the knowledge she’s developed in the process, she’s written two e-books she has posted on her website. One covers the design process for creating the bike, while the second details the construction process of turning the design into a real-life functioning e-bike.

10 . I believe that people should stop texting while driving because it not only endangers themselves but others around them. Family members, friends and strangers can be hurt by a simple mistake; their lives can be overturned(倾覆) completely.
Before I participated in the Thumb Wars campaign, I used to put sticky(粘的) notes inside my car to advise any person that was within it not to text while driving. I posted a quote on my social pages that said, “Drive now text later.” The message especially caught my dad’s attention. Since he is on the road about three out of the seven days of the week, we are all worried about his safety. He decided to never use his phone while driving. When it comes to informing other people about the dangers of texting while driving, I usually bring up conversations about driving which then lead me to lecture them on why they shouldn't text while driving. Thumb Wars has given me a new way and opportunity to prevent people from texting while driving.
The era we live in today is all about technology, and there is always the urge to text. Thumb Wars is an inspirational campaign that fights against that. What I was trying to achieve was to not only change my life, but also try to influence the lives of others for the better. I believe that I can make people realize the consequences of texting while driving. They all know that it is not worth it and could change someone's life instantly. I believe that if there were more campaigns like Thumb Wars there would be fewer accidents because more people would be aware of the effects of texting while driving.
All a person needs is inspiration and efforts to avoid texting while driving. Thumb Wars is a good channel, which makes it the ideal campaign to help with others and make a difference in this world.
