What are you going to do if you are in a burning building？How will you escape？Do you know how to save yourself？ Please read the following passage.
    Escaping a fire is a serious matter. Knowing what to do during a fire can save you life. It is important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not lifts.
    From the lower floors of the buildings, we can use windows. We should learn the best way of leaving through windows with the least chance of serious injury.
    The second floor window is usually not very high from the ground. An average person, hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump out in a right way than to stay in a burning building.
Windows are also useful when you are waiting for help. Be sure to keep the door closed, or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may leaked（渗）into the room.
On a second or third floor, a person can escape through a window that open onto a roof. Then from the roof drop to the ground. Dropping onto cement（水泥）might end in injury. Bushes（灌木丛）and grass can help to break a fall.

    Do you know kind words and light music can help plants grow better? Many people talk and play music to their plants. And many people try very hard to protect their plants from loud noise, strong light and bad smell. That's not all. Some people are very careful about what they say or do in front of plants. They don't talk about unhappy things and won't beat a fly near their plants.

    Do plants have feelings? Many pupils think so. Even a few scientists think that plants have feelings. But most scientists don't agree. They don't think that plants call be happy, worried, angry, loving or afraid. They don't believe that a plant's feeling can be hurt.

    Professor Cleve Backster in America did an experiment and said that plants have feelings like human beings. He published an article in a magazine in 1968. People began to pay more attention to this topic since then.

    The Wandering Earth(流浪地球), China's first successful movie whose background is space, as shown on February 5. It is based on(基于)a short story of the same name by Liu Cixin, China's top  science—fiction writer.

    ⒈Capsule(太空舱)—a core(核心)element(要素)

    The space capsule used in the film has made the audience(观众)interested. "This was the first time anything like that was done, "said Wang Hong, the producer(制片人)of the movie. At first, the production(制作)team planned to use a small space capsule that had appeared in an earlier film, but found that it could not meet their needs for filming.

    ⒉Giant vehicles(巨大的车辆)—key to the film

    Giant vehicles are the key element in the film. Famous actors, Ng Man—tat and Wu Jing, said they could not even imagine what these vehicles would be like before filming, because the idea was far ahead of our time.

    The production team made about 10, 000 props(道具)to show the space better, including the giant vehicles.

    ⒊Saving planet itself

    In the film, the earth itself is pushed forward by 10, 000 giant

thrusters(推进器). It carries 3.5 billion people about 4.2 light years

through space in order to avoid destruction(破坏)by the dying sun.

In Liu's story, each thruster is 11, 000 meters in height.

    ⒋Amazing opening

    At the beginning of the film, it shows the environment and life in an

underground city—a big tree growing upside down, busy bookstores and snack bars and so on. There are also many snow scenes (片段)throughout the whole film.

    Cars make our lives more convenient. But they can also be a problem. For example, fossil fuel(化石燃料) cars mainly cause air pollution.

    To improve the environment, many countries are developing electric vehicles(EVs，电动车). Among them, China is taking a leading role and has created the world's largest EV market.

    Last year, over 40 percent of the 753，000 EVs sold in the world were sold in China, more than twice as large as the number sold in the United States.

    "Filling up a fossil fuel car with gas(汽油) is more expensive than charging(充电) an electric car, " said Wu Hao, who bought an electric car this year.

    However, there are still some problems. It can be hard to find charging piles(充电桩) and the cars can't go far before needing to be recharged.

    Some of these problems are being solved. In 2014, China had 31，000 charging piles. Now China has the world's largest EV charging network, with more than 167，000 charging piles in total.

    Developing EVs is one of many efforts that China has made to cut down pressure on its environment after the government promised to stop increases in carbon dioxide emissions(二氧化碳排放量) by 2030.

    "As China goes, so will the world's car industry，" the Wall Street Journal said. China has taken a leading role in the world's electric vehicle industry.
