六级口语：the increasing use of robots(机器人的使用)
With the fast development of high technology, people are using robots increasingly. Not only do many companies have robots, but more and more people can afford to buy robots, too. For example, in restaurants, robots can replace waiters to serve the guests. For common people who use robots in their households, robots can help clean the house, and even look after the kids. They can do quite a lot of things to entertain people, such as telling a story. But there are also some disadvantages of robots. For instance, they don’t have feelings. Therefore, even though robots can bring much convenience for people, they can never replace people.
