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.

Tips for Chinese Students Studying Abroad
As living conditions in China are getting better, parents who want their children to have a bright future invest large sums of money to send their children to study abroad. However, there are countless difficulties that students have to face and solve when they study abroad. Therefore it is necessary for Chinese overseas students to be aware of certain things to which they must pay attention.
{#blank#}1{#/blank#}
Safety issues before and after studying abroad have been one of the focuses of parents. However, all experts consider psychological preparation as the most important thing for students studying abroad to consider. They believe that students must have a clear picture of their position and know that they are going abroad to study and receive training and not for leisure. And they should not have the opinion that everything abroad is good and all things from China are bad. Students should prepare themselves for the differences.

Chinese students have got accustomed to the domestic exam-oriented education style that is completely different from the more open foreign education mode. They will face changes in the educational system while studying abroad. So students should learn about the differences between the domestic and foreign education styles and try to find more solutions to adjusting to the open education in order to be well prepared for their overseas studies both mentally and practically.

Students should ask related teachers to help make plans consistent with their practical condition. There should be both macro and detailed learning plans. Macro learning plans require students to hold on to the primary direction of their overseas studies and detailed learning plans require them to arrange learning content for each course and semester. After the plan is made, they should strictly keep to them. Otherwise, the plan will have no effect.

As Chinese students are not familiar with the place and people, and have no relatives by their sides, the first feeling they will feel is loneliness, which makes it especially important to learn to develop relationships with people around them. They may meet all kinds of fascinating people abroad. They should go out of their way to be friendly and strike up conversations. The most important thing is to pluck up enough courage to open your mouth and talk with others. Foreigners really like children of this kind and are willing to help them.

Foreign children are used to learning by themselves in or after class, but Chinese children are used to teacher-centered education. Guided and supervised by parents and teachers, Chinese students don't have much learning space. They may score high in exams, but they may lack independent learning skills and tend to be in a state of passive learning. So the most basic thing that children need to know is that studying abroad requires that they should adapt to overseas studies as soon as possible and try their best to learn actively and independently.
