不唯一
Possible version:
Last week I saw wonderful performances by robots at the Science and Technology Exhibition. It was the intelligent robot whose name was Tony that impressed me most. It was 1 meter high and weighed 45 kilograms. It could take the place of humans to do some dangerous tasks. Besides, it could do all the housework, including washing dishes and cleaning the windows and many other kinds of things. Surprisingly, all these would be done easily and automatically. What’s more, not only could it look after patients, but also it could take good care of little children.
Certainly robots bring us much convenience, but they can’t take the place of humans in all aspects of our life. No matter how clever robots are, they are made by humans and they just follow the instructions given to them. Therefore, robots will never completely replace humans.
