According to Tian,Li,Zhao,and Lu,(2007),“In recent years,robots are more and more important for humans,and they supply the best service for the lives of people.” Because it has many advantages,such as improving work efficiency and reducing casualties.To begin with,robot can work for a long time without having a rest.However,when people work for a long time,they have to take a break rather than keep on working.Moreover,according to Yarnasaki,Igarashi,Matsuno,(2004),“robot reduce casualties in some dangerous environments.” Without the help of robot,people have to go work in dangerous environment.Hence,robot play a significant role in people is lives.

According to Tian,Li,Zhao,and Lu,(2007),“In recent years,robots are more and more important for humans,and they supply the best service for the lives of people.” Because it has many advantages,such as improving work efficiency and reducing casual
robots become more and more important to human,and they supply the best services for the lives of people
没有和其他东西对比的比较级应该是变化型的,要用become
human 可去掉s 因为用humans时一般是和动物或其他种类对比
services 要加s 因为服务不是单一的
something is important to somebody某物对某人很重要
it is important for somebody to do something,做某事对某人很重要
Because it has many advantages,such as improving work efficiency and reducing casualties.这句话没有因果关系,应去除because,此外,前面都用robots 我觉得这里则应该用there are many advantages to use them 更好
机器工作其实也需要休息,这叫机械设备调整期所以用robot can work for a long time with little rest这里只是建议,可以不改原句.
最后一句
robots play a significant role in people’s lives

human去s,environment去s,robot加s,is变's
