I think that the world will be an easy place to live in. We1have machines and robots and they will2us do all the3jobs, and we don't have to do things4washing dishes and5the beds, though we won't have any dishes at all. Maybe we will just throw the dishes away after each meal. I6that doctors will be able to7us alive8a long time.

Mr. Green made a robot. He could say only one sentence“There is no doubt(疑问)about it. ”The robot always repeated the same words when you spoke to him.
One day Mr. Green needed lots of money and he took the robot to the market to sell him. “Who will buy my robot? He is very smart, ”he shouted. “Twenty thousand dollars for my robot! ”
A man was surprised that he was asking for so much money. “Is it different? ”Instead of asking Mr. Green why he wanted so much money, he decided to speak to the robot.
“Are you worth(值)twenty thousand dollars? ”he asked the robot. “There is no doubt about it. ”answered the robot.
The man liked the robot's answer so much that he bought him and carried him home. But very soon he found that the robot could say nothing else. He was sorry he bought the robot. He stood in front of the robot and said, “How foolish(愚蠢的)I was to throw so much money away! ”“There is no doubt about it, ”said the robot.
We live in the “computer age”. Today, it is more and more ifor us to use computers. We use them at w, and we also use them at home. Adults use computers and cuse computers, too. We often use the mouse to run all the work.
Slowly, you may fpainful and numb(麻木的)in your hand, your wrist, your shoulder, and your neck. What's wwith you? The mouse is eating your body fyour hand to all. Some researchers explain that we feel painful bwe often repeat the same action—click(点击). So we feel ulittle by little.

Mars is the planet most like Earth. 3. Flying to Mars is a difficult task for humans.
There is an experiment with the name “Mars 500”in Russia. Six volunteers take part in the experiment. They come from China, Russia, France and Italy. They won't go to outer space. They will stay in small modules(太空舱)on the ground for 520 days. It's just like a real space journey(旅程).
In the modules, they will experience a lot: flying to Mars, working on Mars and flying back. During the long “journey”, the volunteers can only eat space food. They can shower every 10 days. They can call their friends or families. 4. Anyone of them can quit(退出)if he doesn't feel well. This experiment helps scientists know how well humans will be on a long journey to Mars.
Wang Yue, 26, from China, is the youngest of the volunteers. He is a teacher at the China Astronaut Research and Training Center in Beijing.
