The world's first hydrogen-powered trains have begun running in Germany. They began carrying passengers Monday in Germany's northern Lower Saxony state. The new train will run 100-kilometer trips and can travel up to 140 kilometers an hour.
A French railroad company called Alstom built the two trains. Team in Germany and France cooperated on the project, which was supported by the German government. The new train model ,called the Coradia ilint, signals the beginning of efforts in Germany and other nations to move away from pollution-producing diesel(柴油) trains.
The Coradia iLint is designed to run on non-electrified train lines with low levels of noise.
It uses a process that combines hydrogen and oxygen to produce electrical power. If the system produces more energy than the train needs at that time, it can store the extra energy in batteries. The only emissions (排放物) are water and steam.
A single tank of hydrogen can run a Coradia iLint train for about 1,000 kilometers. This is very similar to the distance a diesel-powered train can run on with a single tank.
Hydrogen-powered trains cost more than diesel trains to build. But Alstom officials say the operating costs are much lower. The company plans to provide another 14 Coradia iLint trains to Lower Saxony by 2021.
The head of railroad operations in the area, Carmen Schwab, praised replacing diesel trains with hydrogen. She said the move was an important first step in using clean-burning technologies to reach climate protection goals.
Officials say the area's many wind turbines (涡轮机)will produce part of the energy to create the hydrogen to power the trains.
Alstom says several other European countries have also expressed interest in developing hydrogen train systems. France has already said it wants its first hydrogen train to be operating by 2022.

Being highly successful in any field is pretty rare. It takes a combination of natural talent, luck, determination, and plenty of outside support for someone to make it big in sports, entertainment, or business. But what if competing is all that matters to you, whether you are likely to succeed or not? This was the goal of Michael Eddie the Eagle Edwards, and that he reached that goal was an amazing achievement.
Born in the U.K. in 1963, Michael was an enthusiastic downhill skier whose dream was to compete for Britain in world-class competitions. He would have liked to represent his country in the 1984 Winter Olympics, but there were a large number of downhill competitors, and Edwards didn't qualify. Seeing his chance elsewhere, he switched to ski jumping. Ski jumping didn't cost nearly as much, and there was almost no competition for a place on the Britain team.
But number of hurdles (障碍)could have meant the end of Edwards' dream. He weighed more than most competitors, which put him at a disadvantage. He had no financial support for his training. Poor eyesight meant that he had to wear glasses under his goggles (护目镜)- not a good thing when they steamed up at high altitudes. But he couldn't let any of this discourage him. He saw himself as a true lover of the sport who simply wanted the chance to compete. Winning wasn't the point. Having the opportunity to try was all he cared about. And nothing could stop him from trying.
In the end, Edwards took 55th place in the 1987 World Championships. He then went on to the Calgary Olympics in 1988, where he finished last in both of his events. Many athletes would have been embarrassed by this result, but he is proud of his achievement to this day. His determination to fight against all the odds made him a global hero, and in 2016, the inspiring film Eddie the Eagle was made about his life.

Lebanese filmmaker Nadine Labaki has become the first female artist in the Arab world to be nominated (提名)for an Academy Award ,or Oscar.
Labaki directed the film Capernaum ,a film about a Syrian refugee (难民)boy and a Kenyan baby who live without parents on the streets of Beirut. It was nominated for best foreign language film.
Labaki wil1 be one of the few female directors to compete for an Oscar this year. She told the Associated press "I wish there were a lot more women filmmakers this year represented, nominated in the Oscars. But I am sure in a few years we won't be having this problem anymore."

We can't help but acknowledge that there is a fear of refugees in general around the world and there are these walls we are building, and this fear that keeps growing," Labaki said.

If you're looking to fully experience Africa's breathtaking scenery, and have an eye for adventure, then there's only one place to be. Here, inside Africa picks four of the best hikes from across the continent.
1.Kilimanjaro
Make it to the top of Tanzania's 5,895-meter Kilimanjaro, and you'll be standing at Africa's highest point. The mountain is Africa's most-visited hiking destination, attracting tens of thousands of tourists and adventures every year.
You don't have to a technical climber to climb Mount Kilimanjaro; you just need not be pretty physically fit. There are six routes to choose from difficulty, scenery and success. No special equipment
2.Atlas mountains
The High Atlas is an impressive mountainous range in central Morocco that hosts North Africa's highest peak. Mount Toubkal, at 4,165 meters. There's a variety of routes to follow during your climb but inexperienced climbers should note that the hike through the mountain's challenging zones is quite demanding.
3.Mount Kenya
A long-extinct volcano. Mount Kenya is Africa's second-highest peak, at 5,199 meters.
Lying just south of the equator, the mountain's deep valleys and diverse wildlife will guarantee you wonderful scenery and a fantastic hiking experience.
The climb, however, to the mountain's steep ice-capped peaks is quite challenging, making it the most technical, probably, in that East African area.
4.Mount Meru
Mount Meru may forever exist in the shadow of its neighbor, Kilimanjaro, but Tanzania's second-highest mountain (4,565 meters) has its own devotees.
It's less known, but Mount Meru is for the true enthusiast who wants to experience what very few people actually do.
Mount Meru is often used by mountaineers to accustom themselves before trying to conquer Kilimanjaro, or by those wanting a hike with the local Massai.

My name is John and I must share with you an event which took place on Flight 1553 out of DCA. My wife and I were traveling to Miami to celebrate an achievement for her and as you can imagine, we were looking forward to fun, sun and laughter.
We boarded the aircraft, without a care in the world. It was cold in Washington and we were ready for Florida.
Shortly after taking my seat, I began to feel sick. I knew something wasn’t right but just couldn't find out what was happening.Being a doctor and a stubborn man, I resisted efforts by my wife to call for assistance. As the aircraft began its departure roll, I lost consciousness for a short amount of time.
As I came around, I quickly realized a few things. Firstly, something very bad had happened to me. Secondly, the aircraft was too heavy with the fuel to go back home. Thirdly, my loss of consciousness had been so deep that I found myself out of control. So not only did I have a medical issue to deal with, but I also had to figure out how to deal with an embarrassing experience.
My wife gathered the crew as soon as it was safe to move about and I made my way to the washroom to attempt to clean up. I did my best and the flight crew members were so supportive, checking on me often and reassuring me that there was nothing to be embarrassed about.
It was their sympathy and support that helped me so much. During the flight they kept watching over me and I suddenly had a small group of nurses, bringing blankets, food, drinks and caring and smile. I was thankful to them.
Paragraph 1：
Upon landing, I remained in my seat, allowing other people to go first.
