When Goldie Nejat began developing robots in 2005, she spent much of her time knocking on doors to let people know how her robots worked but few showed interest, "But now, it's different," Says Nejat, "People calling from around the world ask when my robots are going to be ready." Nejať's robots are designed to fill an increasing need: care-giving for the old. The population of the people over age 80 will be 426 million in 2050, three times larger than that now.

Such robots could be especially useful for patients with Alzheimer's disease (老年痴呆症 ). They can help with everyday activities from preparing food to reminding(提醒) the patients of taking their medicine. They can also play games with patients to keep them active.

Some have worried that care-giving robots might reduce (减少 ) human interaction (互动) and cause more humans to lose their jobs. "But the aim is to support human care, not to take the place of it" says Brian Scassellati. He has tested robots with different patients, and found that daily interaction with robots can help children with autism spectrum disorder(自闭障碍症) improve social skills.

As a field grows, scientists aim to understand human-robot relationships better. Do robots offer advantages because they don't have feelings and don't give opinions? Will patients lose interest?

"One thing is clear," Scassellati says, "Robots can provide care for the customers and the need for that will increase in the future. "

1.Nejat's robots are designed to________.

A.work in the factory B.make phone calls

C.take care of the old D.knock on doors

C.what the old people can do D.what the old people think of the robots

4.According to Scassellati, we can infer that Nejat's robots ________.

A.will have feelings soon B.can take the place of humans

C.should be produced more D.won't give their own opinions

Nexi is one of a new generation of robots. It moves on wheels and can pick up objects. But robots like Nexi are more than just entertaining toys.

Nexi, a social robot created by scientists at the Massachusetts Institute of Technology (MIT) , can express human emotions. Roboticists at MIT call Nexi a "social robot". A social robot is a robot that can communicate like a human. Nexi can look sad, mad, and even bored. Some social robots can also "read" our facial expressions. Roboticists believe that it won't be long before we have social robots in our homes, helping us live better lives.

Autom is another social robot developed at MIT. Autom is a robot health coach. It has a screen where you enter information about what food you ate that day or how much you exercised. Autom has a face with eyes that move. It speaks with a synthesized voice. Autom gives you advice about your diet and exercise and drives you to do better.

In a test, Autom helped people lose weight better than other ways of recording diet information. Roboticists think this is because Autom used facial expressions and words of encouragement. In other words, Autom communicated like a real person. In fact, many people who used Autom gave the robot a new name and talked to it. When robots use human expressions and body language, people reply to them a lot like they reply to people.
