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

Cycling or Running?

Aerobic (有氧) exercise is an effective tool to assist with fat loss. It can be fun and help build up your body. Running and cycling, for example, are both good for you. 1. Read on and make an informed decision.

Metabolic (代谢) Level

At the metabolic level, fast running beats fast cycling. There is also the fact that when you’re riding downhill, you’re essentially at rest because you’re coasting. Not so with running. 2. You’re also getting more of a total body workout with running than you get with cycling.

Difficulty Of Adoption

You could ride a bike for hours. With no pounding on your joints, you can go far and fast. Now compare that to taking up running. The first few times you try running, you will breathe heavily, wondering why on earth you’re putting yourself through such suffering. It takes enormous determination for most people to become runners. 3.

Racing

Foot races are popular the world over. There are 5Ks, 10Ks, half and full and ultra-marathons. Any decent-sized city will have your choice of races. 4. It forces you to train and pushes you to get better. Contrarily，it’s harder to find many races for cycling.

Convenience

In terms of convenience, running can’t match cycling. You will reach a specific destination way faster on a bike than by running. It’s also easier for carrying things on a bike.

5. Both cycling and running have something to offer. It’s about analyzing their respective advantages and deciding what’s right for you.

A.Truth be told, there is no winner.

Companies can increase the money with which they run their business in a number of ways. One way is borrowing money, and another way is buying things with the agreement that payment would be made later. There are also other processes for providing money for use by a company. Two of these processes are described here.

One process the company may use is to issue bonds(债券). Bonds are a special kind of promissory note. They are issued in different values, in the forms of money used in different countries, such as the pound in England or the euro in Europe. These bonds can easily be sold again to other people or to other companies. The company that issues the bonds promises to pay a particular amount of money as interest regularly for a certain period of time. This continues until when the company has to pay back the principal(本金) of the bond. Payments of principal and interest must be made on time whether the company has been earning money or not. If these payments are not made on time, it means that the company has not done what it agreed to do and can be sued(控告，起诉).

Another process companies may use is to issue other forms of promissory notes called stocks(股票). Bonds and stocks are opposite methods of providing money for a company. The people who buy stocks provide money that is earned and take part in deciding how the company will conduct its business. They must also take part in the losses. The people who own stocks receive dividends only after the company has paid all of its debts to the people who own bonds. On the other hand, the persons who own bonds have no right, according to the law, to help decide how the company will handle its business, unless it is bankrupt or in danger of becoming so.

1. Which of the following statement is not the way for companies to increase their capital?

A. Borrowing money.                                   B. Buying materials without paying.

C. Issuing bonds                                       D. Issuing stocks

2 As to bonds, we know from the passage that ________.

A. they are cheques like bank notes

B. the company only pays back the principal

C. they are issued in the forms of money

D. if a company is bankrupt, it needn’t pay back the interest

3. According to this passage, who have the legal control over the decisions of the business?

A. Stockholders                                          B. Bondholders

C. The government                                       D. The workers in the company

4. It can be inferred from this passage that ________.

A. to issue bonds is a better way than to issue stocks

B. stockholders can sue the company when it is bankrupt

C. bondholders have the same rights as stockholders

D. investing in stocks has more risk than in bonds
