This report talks(单三) about the present and future robot.Recently,we can see robots(用复数,因为你这里不是特指一个机器人) on movies,but we rarely see them in our real life.Scientists think robots can become a part of our life in the future.Robots can (instead是副词,这里用动词)replace human to do some hard works(复数) and challenge works,and robots work faster(fast比较级不要加more) and higher(应该也是比较级) efficiency.But robots have a serious problem,they can be used like weapons.We can give languages(复数) and skills to robots,but we can not give cultures to robots.Now scientists are doing some work to ensure that the robot will not do (do harm to)harm to human.I hope robot will appear in our life.
