Scientists say life will be very different in 2050.First,there will be no TV channels (频道) . People will choose a programme (节目) from a computer and watch it on the television. We will get information on the computers only.

   Second, water will be a big problem. In many places, people won't have water to drink.

Third, cars will use new and clean fuels and they will go very fast. There will be a computer in every car. And computers will control the cars and there won't be any accidents (事故) .

Going Green

Green is no longer just a color. It is a new way of thinking about the world and a way of living your life. It's catching on all over the world. More and more people decide to "go green" because they know that we only have one planet to live on. We won't be able to live on it much longer if we keep wasting energy, and destroying(破坏) our home with air, land, and water pollution.

"Green Living" means:

    Understanding that your choices affect(影响) not just you, but everybody everywhere.

    Understanding that your choices affect not just today, but the future.

Understanding that when we talk about "saving the planet" or "saving the environment," we are actually talking about saving ourselves!

You may be thinking: "Hey, I'm just one person, on a planet with billions. I can't really make a difference." Well, have you ever seen a group of people do "the wave(波浪)"? It always starts off with one or two people, jumping up and down like crazy. Soon thousands of people are joining in. "Going green" is just like that. It starts with small, simple actions. It can soon build into a wave that will change the whole planet and lead us all to healthier, happier lives.

    Many students have already shared with us their efforts to help the environment:

Gabrielle, 12, writes, "I have helped my community plant a garden and I ride my bike or skateboard to school."

Kaitlyn, 10, says, "Lots of paper towels are thrown away, so I use a reusable cloth towel to dry my hands instead."

"I always recycle(重复利用)" says Natalie, 13. "You can call me a recycler! I always look at the bottom of things. I want to see whether they have the little sign that tells you it can be recycled. So I almost recycle everything!"

Now it's your turn to think about how you can "go green". Make important choices and take actions to improve the environment right around you and the health of the whole world.

    When some plates(板块)of the Earth move suddenly, an earthquake happens. Many earthquakes begin under the sea. Earthquakes may happen anywhere on the Earth. They often happen near the mountains.

    During an earthquake, the shakings make rocks rise suddenly and even crack(断裂) open. Houses fall down. People are killed or hurt, and sometimes the whole villages or cities are destroyed.

    Can we do something to keep ourselves safe from earthquakes? Scientists have studied earthquakes and made maps that show the “earthquake belt（带）”. In area of these belts, it's possible for earthquakes to happen. In these areas we should build strong houses to fight against earthquakes.

    In the future, Scientists will be able to tell when and where an earthquake will attack before it happens. They can also tell people what to do and how to deal with it.

    Paulina Cortes is a teacher in San Jose, California. One day, she handed out masks (面罩) to farm workers in Lodi. She volunteered to do this because the air quality (空气质量) is still poor after a big fire.

    "I just got home and feel really tired now. Today I spent my day in Lodi handing out masks to farm workers," she wrote on the Internet. "I raised some money. Then I drove through San Jose and all the way to Salinas to buy enough masks I needed. This is important. The story here isn't that I handed out masks; it's that there are hundreds of people who are working in dangerous environments with no protection (防护). And no one even knows about it."

    Paulina also put some photos on the Internet, and they were picked up by the news. Many people were surprised at the news, and they knew what happened to those farm workers for the first time.

    The next day, Paulina added, "I traveled through Lodi and Stockton not just to hand out masks, but to help the farm workers understand the pollution. In Lodi yesterday the workers were picking fruit in such dangerous environments. None of them even knew this. Not too far from our homes, hundreds of people are working in these environments. I will buy more masks and send them to a Stockton farm worker. He helped me hand out masks yesterday."

    Thank you, Paulina, for caring and trying to make a difference.
