The number of buses, taxis and other transportations on Kenya’s roads is growing every day.
Now, the country’s first electric-powered motorbike is being made. The motorbike is designed（设计）to cut down on pollution. It’s much cheaper so that most of people can afford it.
Most motorbikes used in Kenya depend on gas as fuel（燃料）, but not this new motorbike. Its energy comes from sunlight.
Three university students developed the new motorbike. It receives the sun’s energy, stores it in batteries（蓄电池）and uses it to charge（充电）the electric motorbike.
Robert Achoge is one of the student inventors. “Our hope is that by the fifth year, we will be able to cover the whole Kenya with the electric motorbike in order to improve the environment and provide affordable transport.”
The students have set up a fueling station for the motorbikes in Nairobi. Riders can charge the motorbikes in the station. The small battery can run for 70 kilometers when they’re fully charged. Once the power is used up, the motorbike has to return to the fueling station while another charged battery is connected to the motorbike. The US African Development Foundation is providing some money for two solar-powered charging stations in the Kenyan port of Kisumu.
Each motorbike costs about $700. One motorbike rider says the new motorbike costs less to ride than motorbikes running on traditional fuel. “When talking about buying fuel, there is no need. It’s basically good for everyone. Even though you won’t carry quite a heavy load, you can go with it anywhere.”
A Nairobi dealership is selling the motorbikes. Businessman Kennedy Kusimba hopes they will become popular. “We also know they are more reliable, compared to the gas-powered motorbikes. They are more useful and they will last longer.”

It is often said that dogs are “man’s best friends”.
Wu Qi, a dog trainer in Shanghai, started the Paw for Heal (PFH) program in China about eight years ago. The program trains dogs for animal-assisted therapy (动物辅助治疗). These animals help old people feel quiet and less stressed.
In Shanghai, the dogs have been trained to help kids with autism (自闭症) who are easily scared by their environments. When the PFH dogs are around, they feel much better.
“She (my dog) makes me happy every day, and I think she can bring happiness to other people in need as well,” one of the pet owners Wang Lei said in a report by Sixth Tone.

【推荐2】There have been many disadvantages of wearing face masks (口罩). For example, it’s difficult to breathe and eat or drink something. However, recent research from the UK may have brought us good news: people look better with a face mask covering the lower half of their faces.
The first part of the research was carried out in February 2021, by which time the British people had become used to wearing masks since the pandemic (流行病) started. During the research, forty-three women were asked to give scores for the images of men’s faces without a mask, wearing a fashionable (时尚的) cloth mask, wearing a blue medical mask and partly covered with a black book.
These women said the men wearing fashionable cloth masks were more attractive (有魅力的) than the ones with no masks or whose faces were partly covered with black books. But the blue medical mask made the wearers look even better. This may be a blow to the producers of fashionable cloth masks.
“__________ When we see someone wearing a mask, we no longer think that person has an illness, and I need to stay away. Instead, we feel safer and less worried.” said Lewis, an expert from Cardiff University’s School of Psychology. Lewis said it was also possible that masks made people more attractive because they directed attention to the eyes. He said some other studies had found that covering the left or right side of a face also made people look more attractive, partly because the brain would imagine the missing parts and beautify of the whole face.
The results of the first part have been printed in the magazine Cognitive Research: Principles and Implications. The second part has been carried out, in which a group of men look at women in masks. It has yet to be printed but Lewis said the results were generally the same.

【推荐3】①Height is just one of the thousands of features your genes (基因) decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall too, but if you have questions about how tall you’re going to be, ask your doctor if he or she can help you find it out.
②But genes don’t decide everything. For example, eating an unhealthy diet can stop you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
③No doubt(怀疑) you’re wondering how fast you should grow. It depends. There’s no perfect or right answer. Generally speaking, kids grow about 6 centimeters a year between age 3 and the time when they start puberty (青春期) (when your body starts changing and becoming more grown up).
④Your doctor can know your growth these years. Two centimeters here and 2 inches there are not as important as the height you’re at now, how you’ve been growing up to this point, and what other changes your body may be going through.
⑤Don’t be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt (高峰) during puberty. The age for starting puberty is about 10 years old for girls and about 11 years old for boys. But it can be earlier or later—between 7 and 13 for girls and 9 and 15 for boys. You’ll usually begin to notice that you’re growing faster about a year or so after your body starts to show the first changes of puberty.

【推荐1】AlphaGo has become famous all over the world after it beat South Korea’s top Go (围棋) player Lee Sedol in March, 2017. In the past, people thought computer programs couldn’t beat them in Go games. But AlphaGo did it. Google DeepMind in London developed it to play the board game Go.
In October, the latest AlphaGo came out on the Internet. Its name is “Master”. Then it beat some top Go players, including Park Jung-hwan from South Korea, Iyama from Japan and Ke Jie from China. “I was surprised,” Ke said after three games, “because it took every move almost within five seconds. It’s impossible that ‘Master’ is controlled by a person.” Aja Huang, the programmer of the company, said, “In the past few days, we have checked if it worked well during some online games. And we are still working hard to improve AlphaGo.”
AlphaGo is an example of artificial intelligence (人工智能)—AI. Scientists are now trying to use AI to do many things, such as driving cars and writing stories. Some people worry that the development of AI may mean the end of humans. But the CEO of the company doesn’t think so. “This isn’t about a competition between humans and AI. The development of AI provides humans with another way to discover new knowledge.” Demis Hassabis said.

【推荐3】Imagine this: you and your friend are on a video call. He or she picks up a book, and you feel like you’re holding the book as well. You can shake hands or give your friend a high five, even though you’re not in the same place.
A pair of special gloves might make this possible. Researchers at the University of New South Wales, Australia, have made gloves that can recreate the sense of touch. They call this haptic device (触觉装置) a “soft skin (皮肤) stretch device” (SSD).
The SSD works like this: One person’s gloves create 3D force signals when they touch something. The signals are sent to the other person’s gloves, which vibrate (震动) to create the same force that the first person is experiencing. This allows the second person to experience the same sense of touch.
The SSD allows you to feel force, vibration and motion (移动). “It is like wearing a second skin,” said Thanh Nho Do, one of the researchers who created the gloves.
Haptic technology is already being widely used. For example, the trackpads (触控板) in laptops use vibration to make it feel like you’re using a real mouse. However, it is difficult to recreate the sense of touch in virtual (虚拟的) environments or remotely (远程地), according to Mai Thanh Thai, lead researcher of the SSD project. The SSD is special because it is highly sensitive even when it is used continuously. This makes it feel more real.
The SSD could be used in medical practice. Two doctors in separate places could work together during an operation—one touches the patient’s organs (器官) with the SSD while the other doctor feels the same feelings and completes the actual operation.
1. What does “SSD” refer to?| A．A video chat app. | B．A pair of special gloves. |

Bear Grylls
His name is Bear Grylls, and he was the host of Discovery Channel’s famous TV show, Man vs Wild. In the show, he was left in faraway areas in order to show survival (生存的) skills. Millions of viewers watched, breathless, as he climbed terribly dangerous mountains, performed amazing ice climbing, and ran through a forest fire.
Grylls continues to shine with both his amazing shows and charity (慈善) work. And he has set up his own company, Bear Grylls’ Survival Academy, where everyone can learn survival skills from him and his highly trained team.
Recently, Grylls founded Young Survivors – training courses for teenagers, including survival skills and adventure tasks designed to teach the basic rules of outdoor survival self-rescue. Those who complete the course are given a Young Survivors Award. Skills taught include how to build and light a fire, how to tell directions in both day and night, putting up a protection building, bad weather survival and so on. The key focus of the course is getting young survivors back in touch with nature and away from technology.
In Grylls’ own words: “The thing I love about Young Survivor Course is that it is designed to put young adults in just the kind of challenging, character-building and practical situations that help consider them as adults. So often, young adults can feel almost over-protected and are stopped from experiencing some of the best things in life – but the Young Survivor Award will challenge and empower them in an unbelievable fun environment.”

【推荐3】Many people say that they are working too many hours. They don’t have enough time to relax or to stay with their family.
Work hours are different from one country to another. In France, people spend about 1, 646 hours a year at work. In Japan, however, people work about 2, 159 hours a year. That means a Japanese worker works 513 more hours a year than a French worker.
Why do people work so many hours? Some people work extra hours because they want to make more money. However, many companies don’t pay overtime. Their workers don’t get more pay for more work. Some people think it’s their duty to work more hours. Some are afraid of losing their jobs if they don’t work more hours.
Many people say that their vacations are too short. In France, people get five weeks of paid vacation a year. In Germany, they get four to six weeks, and in the United States, two weeks. One study shows fewer than half of workers used all their vacation days. In Great Britain, there is a saying, “All work and no play makes Jack a dull boy.” If that is true, there must be a lot of dull people in the world.
