The world's first hydrogen-powered train...

    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.

1.Why did Germany build the new trains?

A. To replace diesel trains.

B. To carry more passengers.

C. To make traveling much easier.

D. To develop friendship with France.

2.What is one advantage of the Coradia iLint?

A. It runs without making any noise.

B. It doesn't use electrical power.

C. It costs much less to run.

D. It is cheaper to make it.

3.It can be concluded that hydrogen trains________.

A. are widely used

B. are environmentally friendly

C. can stop air pollution

D. can produce water and oxygen

4.What might be the best title for the text?

A. Saving Natural Resources

B. Efforts to Reduce Emissions

    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.

1.What is the purpose of the first paragraph?

A. To add some background information.

B. To uncover the secret of success.

C. To expect an answer from readers.

D. To introduce the topic.

2.Why did Michael Edwards choose ski jumping?

A. It took less skill.

B. The equipment was cheaper.

C. There was little competition.

D. It was easy to win the championship.

3.After the Calgary Olympics, Edwards _________.

A. felt he had reached his goal

B. was embarrassed by his results

C. switched to film making

D. was glad it was over

4.What made Michael Edwards outstanding?

A. His determination to win.

B. His enthusiasm for the sport.

C. His attitude towards the Olympics.

D. His ability to overcome physical disabilities.

    DNA analysis has revealed family relationships between more than 10 generations of Stone Age people at megalithic (巨石的) tombs in Ireland and Sweden.

The evidence suggests that megaliths, prehistoric large stone structures, sometimes acted as graves for family groups in northwestern Europe thousands of years ago. The latest findings throw new light on the origins and social structure of the groups that built megaliths in this region—a history that has long been hidden in mystery.

For their study, the international team of researchers analyzed the genomes—the complete set of genetic material in a cell—of 24 Stone Age individuals from five megalithic burial sites in Ireland, Scotland and Gotland, a large Swedish island in the Baltic Sea.

This analysis showed that many of the individuals buried at each megalith, who all lived between  3,800 B.C. and 2,600 B.C.,  according  to  radiocarbon-dating  of  their  remains,  were closely related via family ties.

The results also showed that the individuals buried at the megaliths were related to Neolithic farmers in northern and western Europe but genetically distinct from other hunter-gatherers. This was particularly noticeable at the Ansarve site on the island of Gotland.

“The people buried in the Ansarve tomb are remarkably different on a genetic level compared to the individuals dug out from hunter-gather contexts, showing that the burial tradition in this megalithic tomb, which lasted for over 700 years, was performed by distinct groups with roots in the European Neolithic expansion,” Magdalena Fraser, co-first author from Uppsala University, said in the statement.

1.What’s the significance of the new findings?

A. It reveals the family ties between people in Ireland and Sweden.

B. It implies that many people buried in the tombs were closely related.

C. It indicates the long-hidden mystery concerning DNA analysis.

D. It suggests that the megaliths became tombs thousands of years ago.

2.How did the researchers reach their findings?

A. By interviewing individuals. B. By travelling to different regions.

C. By analyzing genes. D. By studying the burial sites.

3.Which is true according to the latest findings?

A. Some people buried in the tombs were related to farmers.

B. Few people buried in the tombs were genetically different.

C. All the people buried at megaliths had family relationships.

D. People buried in the Ansarve tomb were dug out 700 years later.

4.What’s the main idea of this passage?

A. Megaliths served as tombs thousands of years ago.

B. People buried at the megaliths were recently analyzed.

C. Latest findings shed light on a mystery about burials.

D. Stone-Age people in Ireland and Sweden had close ties.

    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.

1.What do we know about Kilimanjaro?

A. It's comparatively easy to climb.

B. It's Africa's second highest mountain.

C. Its six routes are equally difficult.

D. It lies to the east of Tanzania.

2.Why do mountaineers climb Mount Meru first before they do Kilimanjaro?
