I'm very optimistic about the future. I believe that robots will do more things, which can make life easier. Especially in the medical service, tiny robots will repair the damaged DNA and attack cancer cells, so that we can live longer beyond imagination. Unless the technology improves, we can't always  keep healthy. In the hospital where I work, there is a robot can do surgery. It has more flexible fingers and rapid reations, and it never feels tired. I belive we will conquer cancer with the technology developing. Life will be better in the future.

I'm very optimistic about the future. I believe that robots will do more things which people are not capable of. These will can make life easier. Especially in the medical service, tiny robots will go into one’s cells to repair his damaged DNA and attack cancer cells, so that we(wa) may live longer beyond our imagination. Without the advancement of modern medical treatments, we can't always keep healthy. In the hospital I work, there is a robot can do surgery. It has more flexible fingers and joints rapid joint relations(reations), and it never feels tired because the only thing it needs is electricity. I believe we will conquer cancer in the coming decades with the technology developing. Life will be better in the future.
