阅读下面短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。

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.”

A well-known speaker started his talking by holding up a $20 bill.In the room of 200, he asked, "Who would like this $20 bill?"

Hands started going up.He said, "I am going to give this $20 to one of you, but first, let me do this." He began to crumple(弄皱) the 20 dollar note up.He then asked, "Who still wants it?" Still the hands were up in the air.

"Well," he replied, "what if I do this?" He dropped it on the ground and started to grind it into the floor with his shoe.He picked it up, now crumpled and dirty.

"Now, who still wants it?" Still the hands went into the air.

"My friends, you have all learned a very valuable lesson.No matter what I did to the money, you still wanted it because it did not decrease in value.It was still worth $20."

"Many times in our lives, we are dropped, crumpled, and ground into the dirt by the decisions we make and the circumstances that come our way.We feel as though we are worthless; but no matter what happened or what will happen, you will never lose your value." "Dirty or clean, crumpled or finely creased, you are still priceless to those who love you.The worth of our lives comes, not in what we do or who we know, but by ...WHO WE ARE."
