Some of us students are still afraid to sleep alone. But my robot(机器人) can help. It can read stories and sing songs to your when you go to bed. You can have a nice sleep every night with it.

I’d like to make a robot cleaner. Our parents are very busy with work, but they still have to do some housework when they get back home. A robot cleaner can help with the housework a lot. Then Mom and Dad can play or talk with us. Isn’t it great?

All robots should be able to protect their owners. My robot is as powerful as the famous hero, Robocop. But it is much smaller. It looks like a student. We go to school together every day. But when there is an emergency(紧急情况), it will protect us students and fight against the bad guys at once.

I often feel lonely, so my robot will be very friendly and kind. It can know your feelings and react like your friends. I will also let the robot read, so it knows a lot and can teach us about right and wrong, just like our parents. In a word, with my robot, you won’t feel lonely any more.
