In some science fiction movies, evil robots refuse to die, no matter how hard people fight back.

    Now science fiction has become science fact. For the first time, scientists have made a robot that can take a beating (挨打) and keep on going. Scientists from Cornell University made the robot, which looks like a spider with four legs.

    Until now, even the most advanced (先进的) robot was almost certain to break down when it was damaged. That is because its computer inside simply doesn't know how to make the machine work after its shape has changed.

    To deal with this problem, the scientists put eight motors (发动机) and two sensors (传感器) that read how the machine is working. They all give signals to the machine's software. Using this information, the computer can then figure out the machine's shape at any moment.

    The new technology is a big advance in robot-making, scientists say, and it's far from scary. It may someday help scientists create better artificial (假的) arms and legs and give new freedom to people who lose them. It might also help scientists understand how people and animals figure out their own sense of place in space.

    “It has been difficult to design robots that can work well when the environment changes or when it's damaged,” says Olaf Sporns of Indiana University in US. “With this work, we are nearer to solving this problem.”

    RIVER DOLPHIN RUNNING OUT OF TIME

The Yangtze dolphin is the only kind of dolphin that lives in freshwater all its life. Scientists say that the finless freshwater dolphin that has lived in the Yangtze River for over 20 million years, will die out in 15 years. It's in danger of disappearing forever.

    Dangers:

    Dredging(挖掘) of their habitat

    Heavy boat traffic in the Yangtze River

    Insecticide(杀虫剂) and mercury(汞)

What is hope? Bernadette Russell, who wrote the book How to be Hopeful, says, "Hope, on one hand, is the knowledge that things can get better. {#blank#}2{#/blank#}" Russell speaks of people who have got over very difficult moments, such as firefighters (消防员). Once one firefighter said, "{#blank#}3{#/blank#}" explains Russell.

However, hope is also about taking action. "From winning the World War II to people traveling thousands of miles away to build a new home, there is a long history of taking actions with hope," says Russell. {#blank#}4{#/blank#} Scientists say that having hope in difficult moments can help you worry less, feel calmer and improve your feelings.

How to be hopeful? Being disappointed and feeling bad are part of life. If it's possible to see hope in those moments, you should. If it isn't, don't worry. Try to keep eyes on good things. For example, you can't change the fact that someone is bad to you. {#blank#}5{#/blank#} Even in the most terrible situations, you can decide what you say and do to each other.
