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 (先進(jìn)的) robot was almost certain to break down when it was damaged (毀壞). 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 (發(fā)動(dòng)機(jī)) and two sensors (傳感器) 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.”

1.Why do robots easily break down when they are damaged?

A．They cannot repair themselves.

B．The computer has changed a lot.

C．They have no computers inside.

D．The computer cannot work if the robot changes.

2.The new technology(技術(shù)) allows the robot to        .

A．keep working after being damaged

B．tell people where it is

C．do house work for humans

D．remember a lot of information

3.The underlined word “them” in Paragraph 5 refers to       .

A．sensors           B．robots            C．scientists          D．a(chǎn)rms and legs

4.How do the sensors in the robot work?

A．They can replace the computer when it’s broken.

B．They help the computer learn the robot’s condition.

C．They can find out where the damage comes from.

D．They can send signals to the person who uses the robot.

I love it at night. It’s peaceful. And when it cools down I sometimes do some ironing. I don’t really care for it. I work full-time and I am too busy for most housework. I remember the old woman who taught me to iron. I was about 15 and I had to get a job taking care of a woman to make a living. She had been an able-bodied, healthy woman until the accident that caused her to be paralyzed.
The woman sat in an electric wheelchair all day. She could only move her head and arms. She would tell me how to do things. She would teach me in great detail on the correct ways to do things. Her home was perfect and beautiful. She would follow me around in her electric wheelchair to make sure I did everything exactly right. I’m sure she had been a perfect homemaker. She would have me fold(折疊) everything, including socks. I would complain silently and wish terrible things on her. She taught me the right way to make the bed. I know sometimes she’d get frustrated(沮喪) and impatient with me. I knew she wanted to do it herself. But she never shouted or scolded. She only insisted I do it right. I didn’t like it much, but I did it.
Today I can iron pretty well. I know where to start on a shirt and the right way to do the trousers. Now when I think about it, I don’t think she is an old lady. I think she might have been about my age now. Anyway, when I iron, I think of her and silently thank her for all the things I learned.
【小題1】The writer used to take care of the lady because ________.
A．she wanted to learn to do housework
B．she was a friend of the lady’s
C．she had to earn some money
D．she couldn’t find a room to live in

A．destroyedB．deafC．seriously illD．unable to walk
【小題3】The little girl was ______ when the lady taught her how to do housework.
A．encouraged to learnB．unwilling to learn
C．delighted to learnD．recommended to learn

A．is still afraid of the ladyB．hates the strict lady

I didn’t think I had a passion(激情). I would sit in front of the TV all day, thinking about nothing but the next show. It was not long ago that I first learned how important having a passion is to life.
That day I went with my mum to drive my sister to the gym. I was bored. Then, as my mum stopped at a red light, someone on the side of the road caught my eye（吸引我的世界）. It was a man dressed in rags (衣衫襤褸). He was homeless. That didn’t interest me, for I had seen many like him before.
But in some ways he was different. This man was not sitting down with a sad expression(表情). He had a radio in his hand and was dancing happily to the music. The radio seemed to be the most precious(珍貴)thing he had.
“Mum, why does that man have a radio even thought（盡管） he’s homeless?” I asked.
“He bought it,” she replied. I was still unable to understand.
“But if he’s homeless, why doesn’t he use the money to buy food or clothes? He wasted it on something he doesn’t need.”
“Well, Sarah, sometimes food and clothes aren’t the most important things. We need happiness, too.”
The man must care too much about music to buy a radio instead of food clothes. I soon realized（意識到）that happiness is the key to life. Without it, there’s nothing to look forward to.
Since then I’ve never gone a day without thinking of what’s truly important. A home, a meal, clothes—these things are only part of the picture. What’s often forgotten is that we all need a pleasure, a light in a dark day. We all need a passion
