英文小作文：

I like to fiddle around with my new toy, a robot that can move its head and arms and even speak to me. I can program it to do different tasks, like cleaning my room or fetching my books, and it always does what I ask it to do. But what I like most about it is that it is always ready to play with me, even when I am feeling sad or upset. It is a great way to relieve stress and have fun at the same time. I hope one day I can have a real robot friend like it.
