Robots have a long history. The first one was made by a Greek inventor(希腊发明家). You may see robots in some movies. The robots in these movies are stronger,     1     and cleverer than people. In real life, most robots are used in factories. They do many     2    , difficult or boring jobs.

Some people can’t look     3     themselves and robots are used to help them. For example, some people can’t see, so many of these people use a dog     4     themselves move around. This dog is called a guide dog.     5     are making a robot to help them. In the future, robots might take the place of(代替) these guide dogs.

Robots are     6     used in hospitals. At one hospital, a robot     7     meals from the kitchen to the sick people’s rooms. It never loses its way     8     it has a map of the hospital in its computer systems(系统).

In the future, robots     9     in space. They can help     10     in a lot of different ways. But robots will never take the place of humans.

Life in the year 3044 is very different     1     life in the 21st century. We still do many of the things you did, but we do them     2    . For example, we now have e-friends to help us and keep us company. An e-friend is a machine that looks just like a person. It can walk and talk and can do almost everything we do. My e-friend is a lot like me and we have a lot of     3     together. She helps me with my homework and we often go     4    . She is able to take care of me if     5     happens, so I always feel     6     when we are together. She can also send me messages, just like the old-fashioned e-mail, and I can download information from her memory. It's great to have an e-friend—I am     7     lonely(寂寞的) and I always have someone to talk     8     .

I would like     9     you more about life in the year 3044, but I     10     send my e-friend to clean my room. Maybe one day I will be able to travel back in time and visit you.

Robots don’t seem new to people now. And they have a long     1    . The first robot was made by a Greek inventor. You may see robots in some     2    . The robots in these films are stronger, faster and     3     than people. In real life, most robots are used in factories. They are used to do many     4    , difficult or dangerous jobs. Some people can’t look     5     themselves and robots are used to help them. For example,     6     some people can’t see, they can use a dog to help themselves move around. This dog is     7     a guide dog. Scientists are trying to make a robot to help them. In the future, a robot dog may take the place of a guide dog.

Robots are also used in American hospitals. At a hospital, a robot     8     meals from the kitchen to the patients’rooms. It never loses     9     way because it has a map of the hospital in its computer system.

In the future, robots     10     can help us in different ways will work in space. But they will never take the place of humans.
