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 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 (毁坏). 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.”

Wonder why you can get angry so easily while your friend smiles all the time? It’s probably because you both have different personalities(个性).
Personality is also about how people think, behave, and react (反应) to everything around them from day to day.
So what makes people think and behave in certain ways?
Part of the reason is that people are born like this. A baby gets its blood type, genes (基因) and other physical things when it’s still inside its mother. These things may help decide what the baby will be like.
But one’s personality doesn’t stop here. Family life, school learning and life experiences can also make you the person you are. This doesn’t mean it’s impossible to change your personality. You can always try to make yourself better. Don’t get too worried about your shortcomings (缺点). Just accept them. This is a good way to start making changes.
If you don’t know how to make friends, find out why. Is it because you’re too shy? Tell yourself to smile at people. Start talking to people using warm greetings.
Don’t give yourself a hard time about it all. It’s not easy to change lifelong habits in one night. Keep working at it. One day you’ll see that you can turn over a new leaf and be a new you!

Robby was 11 years old when his mother (a single mom) sent him to have his first piano lesson. I prefer that students begin at an earlier age, but Robby said that it had always been his mother’s 1 to hear him play the piano. So I 2 him as a student.
