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 guard factories, warehouses（仓库）and museums at night.
The mobile robots will move around slowly on wheels. They will be able to detect（察觉，发现） people through walls and pick up sounds, such as breaking glass. They can be fixed with loud sirens 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 prevented from entering the area it moves.
One kind of mobile robot will be able to “sense” whether a chair or a box has been moved and go around it. This robot will also judge size well enough so that it won’t send an alarm 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 is hard to be stolen anyway. It weighs about 200 pounds.
U.S. companies pay almost $10 billion a year to protect their property with alarm systems and human guards. Mobile robots may be cheaper.

When I was seven years old, my mom was diagnosed（诊断）with cancer. The doctors told us my mom might be saved with operation. But it could also kill her. She chose to have it.
The day before the operation I was off school, and my mom planned the best day of my life, everything I loved at seven and everything that would put a smile on my face. The day began with her waking me up saying, “Kate, I have a surprise for you. Come and see.” The surprise was a doll I had wanted for the longest time. Throughout the day, she told me everything that she thought I would need to know to grow up and be a good person; she told me to be the best I could be and that I would always make her proud. We had a picnic in the park, and it was so cold that we moved to the car. The day was filled with laughter. For the first time in a long time I could see she was really happy. I would never forget her smile, or the way her eyes shone as if we were the same age. It was the best day of my life, and I will never forget the conversations we shared.
My mother managed to live through the operation. Now when I look back, I realize that the best day of my life could be her last and this could be the last day I would remember with her, the last one we shared. I also understand how unselfish a mother is.
