[单项选择]There are robots all around us. Some do very complicated jobs like flying airplanes and driving subway trains. And some do one simple job.
When an automatic washing machine is switched on, water pours in. The machine waits until the water is hot before washing the clothes. It does this by "feedback". Information about what is happening is "fed back" into the robot to tell it what to do next.

It was my six-year-old son’s winter break form school, and we were heading home from Fort Lauderdale after a weeklong trip. The flight was overbooked, and Delta, the airline, offered us $400 per person in credits to give up our seats and leave the next day. I had meetings in New York，So I had to get back. But that didn’t mean my husband and my son couldn’t stay. I took my nine-month-old and took off for home.
