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 t he 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.”

Everybody makes decisions in daily life. They can be as important as what you will do in the future or as simple as what you will eat for breakfast. Any decision could be the turning point of your life.

I made an important decision when I was in Junior 3.

Before I made that decision I wasn’t a good student. I didn’t listen to my parents or teachers, and my grades became poor. Then came the high school entrance exam.

At the turning point of my life, my mom wanted to have a conversation with me. I felt impatient but when I looked at her eyes, I felt I couldn’t refuse. Instead of asking me to study hard, to my surprise, Mom just asked what I wanted to do in the future. Without thinking too much, I just said I would like to study hard.

Mom smiled and asked again: “I asked: what do you WANT to do?”

I had never seriously thought about the question before. So, I kept silent.

“Whether you want to go on studying or enter the society,” she went on, “it is your own decision. It should be made by yourself, not anyone else, including me. ” After saying that, she had tears in her eyes.

For the first time in my life I was asked to make my own decision. I sat in my chair and thought about my life, my future and what kind of person I wanted to become.

It took me what seemed to be ages to make the biggest decision so far in my life—I wanted to be a man who makes a difference in the world. To achieve that, I needed to study hard.

The path to my future became clear to me. I didn’t act rebelliously(叛逆地) any more. With passion (激情) in my heart, I studied hard.

Now, I’m 17 and I’m in one of the best schools in my city, in one of the best classes at the school and I am one of the best students in the class.

Thanks to that decision, I have become what I am today.
