Gasoline (汽油) prices are getting higher and higher. The prices make it hard for drivers to afford the fuel. One group held a special event to display（展示）new kinds of cars .The new cars are different and they can run on many different kinds of fuels.

Some of these cars are called hybrids(混合动力). They can run on different kinds of fuels. One kind of them runs on a special fuel cell which is filled with a gas called hydrogen.

      The fuel cell cars are also better in another way. They give off no emissions（排放物）. They are very clean, and don't give off bad fumes when they are running.

One man who makes fuel cell cars is excited about the hydrogen fuel cell technology. He says we will never run out of the sources of the fuel, but we may run out of the oil. Once we use oil up, it will take millions of years for more oil to form. Since gasoline is made from oil, that could be a problem for companies that make traditional cars, and for drives. However, it won't be a problem for cars that run on fuel cells.

      Buses that run on hydrogen fuel cell power are being tested on the road. They could become a common form of transportation in the near future

    For many smart phone users, especially young people, scanning QR Codes（二维码）has become a new and convenient life style these days. In fact, the QR Code was created in Japan in 1994, but until 11 years later, it was first used in China. It soon became popular around the country.

    The population of the world is still going up and scientists are worried that there will not enough food for us in the middle of the century. One plant from Madagascar, the Kalanchoe fedtschenkoi, may help. It takes in carbon dioxide (二氧化碳) at night and it needs 10 times less water than food plants like rice. This means it can grow in the desert(沙漠).

    It is dangerous to eat this plant, but scientists can study two things about it: how it takes in carbon dioxide at night when other plants only do this during the day, and why it is so good at living in the desert. There will be less good land for growing food in the future because deserts are increase in size. There, growing plants will be more and more important.

    There is a possible way to take this research. To grow a desert plant to eat will be difficult, but it may be possible to use the genes(基因) from this plant and put them into food plants like beans or potatoes. And the food plants with the genes can grow in the desert. We hope the plant could be an answer to our future food.

    As is known to all of us, Beijing Opera is one of the most important opera styles in China. It is an art on the stage which has about 200 years' history. It is not only a treasure of the Chinese nation but also a cultural symbol of China. Similar to western operas, Beijing Opera is a combination of singing, dancing, martial arts, music and literature, so it is also called the "Oriental (东方的) Opera" by western people.

    Beijing Opera uses special imagery in creating the characters. All roles are divided according to sex, personality, age and profession and social status. Hangdang is the general term for role in Beijing Opera. There are four types of roles in Beijing Opera today. They are sheng, dan, jing and chou. The sheng is the male protagonist (主角), the dan the female protagonist, the jing (painted face) a male supporting role with a different characteristics, and chou (clown) a comic or negative figure. Each kind of role has their own face-painting and dressing to indicate their identities.

    The Opera's performance requires not only the gentle voice but also the proficiency (熟练) of martial actions. A successful opera actor must suffer from the tough practicing period. In the old time, the children of poor families were sent to the opera group in order to earn a living. While now, the real opera artists are well respected by opera lovers.

    Mei Lanfang, one of the most remarkable performing artists in Beijing Opera, was born in Beijing into a poor family. His life was bitter and he had no opportunity to go to school, so he went to the troupe (戏班子) when he was 8 years old to learn Beijing Opera. Mr. Mei was on the stage when he was 11 years old to perform the plays of Beijing Opera. He has been an opera actor for more than 50 years, performing hundreds of traditional plays and over 30 modern plays. He portrayed many bright and lifelike female figures on the stage and became the model in Chinese Beijing Opera and even within the entire artistic circle.
