Unit 6

     My invention is a robot. It took me about two years to make it, and it was made by hand. The robot is about 2 meters tall, and it is made of steel. My invention can help people do chores. It can sweep the floor, wash clothes and do the dishes. It's quite helpful, isn't it? You needn't worry you can't use it well, for it is very easy to use . What's more, it can even talk with you in English. And it is very environmentally friendly.All in all ,it'll make your life very convenient.

      That' s all. Thank you.
