Many companies use guards and expensive alarm systems to protect their property(财产)。 Soon a new kind of protection will be used- robots. Engineers have been working on the first mobile robots for businesses. The robots will patrol(巡逻) factories, warehoues(仓库),and museums at night.
The mobile robots will move around slowly on wheels. They will be able to detect people through walls and pick up sounds, such as breaking glass. They can be fixed with lound sirens(警笛) to frighten thieves, or radios to signal police or guards.
To protect a building, a robot will have to move around without knocking into the walls. Information about the building will have to be stored in the robot’s small, built-in computer. A floor map could be programmed into the computer’s memory, for example.
A mobile robot will not be able to do everything. Unlike human guards, it will not be able to climb stairs, open doors, or move along rough ground. It won’t be able to tell the difference between friends and enemies. Because of that, people will have to be barred from the area it patrols.
One kind of mobile robot will be able to “sense” whether a chair or box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alam if a cat crosses the room. And if someone tries to steal this robot, it will sound a loud, painful siren. The three-foot-tall robot will be hard to steal anyway. It will weigh about 200 pounds.

Music can be a great power (力量) to change people’s lives. Regina del Carmen Sanchez, 14, always believes this. The girl from Kansas City, US, leads a hard life. She lives in a small house with her mom and grandparents. Her mom gets a very low pay.
But it doesn’t stop Sanchez’s love of music. She wrote her first song Keep Your Head Up when she was 12. It described the bad situation(情况) at her home, but it also sent the message of hope: “My house is old and poor, but it beats (胜过) being homeless… Love yourself and never give up. You’ll see a better life if you keep your head up…”
It took Sanchez several months to finish the song. Sometimes during a break in class, when lyrics (歌词) came into her head, “I would have to write them down right then,” she told the local newspaper The Kansas City Star.
Jeremy Lillig was a spokesman for Bright Futures, a charity fund. When he saw the video of the song, he was moved. He shared it through social media (社交媒体). The fund has provided money for poor students in Kansas City.
Now Sanchez often plays the song in public. “I want to help people understand what is happening in the world in an easy way,” she said.There are people in Sanchez’s family.

Many years ago,when I was working as a volunteer(志愿者)at a hospital, I got to know a little girl named Lisa. The poor little girl had a very serious disease and was dying. The doctor had done his best but no medicine really worked. The only chance to save her seemed to be a bloodtransfusion(输血)from her five-year-old brother. The little boy had the same disease before and had developed the antibodies(抗体)to fight the illness.
The doctor talked to the little boy about what they planned to do, and asked him if he would be willing(愿意的)to give his blood to his sister. I saw him hesitate(迟疑)for a moment. He took a deep breath and said, “Yes, I’ll do it if it can save Lisa.”
As the transfusion was going on, the little boy lay quietly in bed next to his sister. He 1ooked at her and smiled all the time. When everything was done and the colour returned to his sister’s face, his smile disappeared and he looked a little afraid. He 1ooked up at the doctor and asked, “Will I start to die now?”
