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
C. World's First Hydrogen Trains
D. A New Way to Make Electricity

The world's first hydrogen-powered superyacht (超级游艇)could be taken to the waters in the not too distant future. Dutch yacht-design company Sinot has launched a model for a wonderful concept that seems to develop the superyacht industry in a more eco-friendly direction.
Created in cooperation with Lateral Naval Architects, Aqua measures 112 meters and will be powered entirely by liquid hydrogen and fuel-cell technology, which essentially means water will be its only emission. The superyacht, which has state-of-the-art facilities, is to operate at a top speed of 17 knots (节), with a range of 3, 750 nautical miles.
"For the development of Aqua, we combine inspiration from the lifestyle of a forward- looking owner and cutting-edge technology in the 112-meter superyacht, "Designer Sander Si-not said in a statement shortly before a detailed model of Aqua was revealed at the Monaco Yacht Show in September. He added, "Our challenge is to use fully operational liquid hydrogen and fuel cells in a true superyacht that is not only groundbreaking in technology, but also in aesthetics (美感)。"
Aqua's technology system will rely on two 28-ton vacuum isolated tanks. The energy will then be submitted to the switchboard and distributed, in order to provide power for travelling and hotel services.
The outside and inside design for Aqua, which took developers five months to design, was almost as impressive as its technology system. Aqua will have a yoga space, a swimming platform and a beach deck close to the waterline.
While it's just a design concept at the moment and there are no exact plans to roll Aqua out, according to Sinot, the pioneering design clearly prefigures the superyachts of tomorrow. Earlier this year Latvia's Latitude Yachts announced plans for the Valkyrie Project, a massive superyacht that would span 229 meters, making it the largest in the world。
1.What is Aqua special about?
A.Its steaming distance.
B.Its hotel services.
C.Its energy materials.
D.Its modern facilities.
2.What's the biggest difficulty of constructing Aqua?
A.Poor financial support from the government.
B.The technological problems of dealing with power.
C.The difficulty of designing its whole aesthetics.
D.Lack of resources to produce the components.
3.What can be inferred about Aqua?
A.It will look like a real hotel.
B.It will be created in Dutch.
C.It will open a new era of superyacht.
D.It will be the largest in the world.
4.What is the author's purpose in writing the text?
A.To advertise a superyacht.
B.To show a new technology.
C.To tell us a green travel style.
D.To introduce a superyacht model.

Scientists in Mexico have just begun a new study of one of the world’s biggest pyramids: the Pyramid of the Sun, north of Mexico City. They’re putting lots of small, high-tech machines under the pyramid to try to unlock some of its secrets. For thousands of years, people have tried to uncover the secrets of the pyramids.
The people who built the pyramids made lots of secret doors and rooms to stop robbers from finding the treasures inside. However, there always have been some smart thieves in history. Now, almost all of Egypt’s pyramids have been robbed, including the Great Pyramid of Khufu, which is the largest pyramid in the world. It is the only one of the ancient wonders of the world that is still standing.
In AD 820, an Arab king named Abdullah AL Manum got a group of workers to dig their way into the Great Pyramid and have a look. Inside the pyramid, they found three rooms --- the Queen’s Chamber, the Grand Gallery and the King’s Chamber. But to their surprise, the men didn’t find the treasures they wanted. The Queen’s and King’s Chambers were both empty! Where were the King’s mummy and his treasures? Had someone already taken them away? The huge stone doors at the pyramid’s entrance were still closed when AL Manum’s men went inside. How had the thieves got in and out?
Since then, many people have gone inside the Great Pyramid to have a look or to try to take things. But still, no other chambers or walkways have been found.
In 2002, an American team made the most recent visit to the Great Pyramid. Scientists sent a robot into the pyramid, but they only found a mysterious locked stone door.
1.The first two paragraphs were written to show that ________.
A.the Pyramid of the Sun is an unusual historic building
B.ancient Egyptian emperors were cruel
C.construction workers led a hard life in ancient Egypt
D.the secrets of the pyramids remain to be uncovered
2.What is the purpose of making some secret doors to the pyramids?
A.To try to unlock some of its secrets.
B.To stop robbers from finding the treasures inside.
C.To refuse some visitors all over the world into it.
D.To tell the truth to the people in the future.
3.Which of the following is NOT true to the Great Pyramid of Khufu?
A.It is the largest pyramid in the world.
B.It is the only one of the ancient wonders that is still standing.
C.Abdullah AL Manum took the King’s mummy and his treasures away.

Some developed countries in the world have begun to shorten working hours. Japan, on the other hand, has been in the culture of overwork. The problem is so severe that the country has even created a term for it: karoshi, which means death by overwork from stress-induced illnesses or severe depression. If the system of four-day workweek is tested in Japan, what will happen?
A growing number of smaller companies are adopting a four-day workweek. Now the results of a recent trial at Microsoft (MSFT) suggest it could work even for the biggest businesses.
The company introduced a program this summer in Japan called the “Work Life Choice Challenge,” which shut down its offices every Friday in August and gave all employees an extra day off each week.
The results were promising: While the amount of time spent on work was cut dramatically, productivity — measured by sales per employee — went up by almost 40% compared to the same period the previous year, the company said in a statement last week.
In addition to reducing working hours, managers urged the staff to cut down on the time they spent in meetings and responding to emails.
They suggested that meetings should last no longer than 30 minutes. Employees were also encouraged to cut down on meetings altogether by using an online messaging app (Microsoft’s, of course).
The effects were widespread. More than 90% of Microsoft’s 2,280 employees in Japan later said they were impacted by the new measures, according to the company. By shutting down earlier each week, the company was also able to save on other resources, such as electricity.
1.Why is the idea four-day workweek tested in Japan?
A.Because overwork has caused serious problems.
B.Because the offices must be shut down on Friday.
C.Because the staff can get extra days to rest easily.
D.Because smaller companies have taken the measure.
2.What’s the result of adopting a four-day workweek?
A.It is a waste of energy.
B.The workers earned less money.
C.The working efficiency increases greatly.
D.Japan’s unemployment rate is barely rising.
3.How can the time the staff spent on meetings be reduced?
A.By cancelling meetings.
B.By using emails to respond.
C.By cutting down working hours.
D.By using a certain online messaging app.
4.What is the staff’s attitude to the new measures?
A.Supportive. B.Negative. C.Critical. D.Indifferent.
