Now a roboticist at the University of Southern California in Los Angeles. Maja Mataris is leading a team that programs machines called socially assistive robots. Matari wants her team’s robots to help people who have diseases or physical disabilities. For example, a person with Alzheimer’s disease, which causes problems with memory and brain function, might need help with mental exercises. A person trying to regain the use of an arm after a stroke might need encouragement to keep doing helpful exercises. Because there are not enough people to provide all of the help that’s needed, Matari says,“Technology has to step in.”

In one study, Matari’s team tested a robot with people recovering from a stroke. A stroke is caused by a broken blood vessel in the brain or a blood clot that prevents blood from flowing to the brain Small regions of cells die during a stroke. So afterward part of the body, like an arm, may become weak or numb. A patient has to keep exercising that arm to recover. Those exercises can be difficult and unpleasant, however.

Matari and her colleagues programmed a knee-high robot to ask a patient to perform an exercise and to then monitor the patient’s movements. If the person actively used his or her arm, this robot would say encouraging things.

The team tested the robot with six people actually recovering from a stroke. Patients tended to perform their exercise longer and follow instructions better when the robot was present than with no prompting.

Next, the researchers tested whether the robot’s personally affected how people responded to it. The robot could be directed to move in close, speak loudly and make forceful statements, such as“You can do it!”Other times, the researchers would program the robot to act more shyly. At these times, the robot kept a bit of a distance and softly offered gentle suggestions, such as“I know it’s hard, but remember it’s for your own good.”

ri and her team are developing robots that could be used widely              .

A.  in medical fields           B. in learning and teaching

C. in saving people’s lives    D. in helping people out of trouble

saying “Technology has to step in”, Matari probably means     .

A. the robots can take the place of human beings.

B. the robots have to be used to help the disabilities

C. technology has developed rapidly    

D technology has entered our daily life

rding to the team’s study, the knee-high robot    .

A. could keep blood vessel from breaking

B. benefited the person with a stoke a lot

C. set a good example to the serious patients

 D. forced the patients to do some tiring things

could unhealthy people keep exercising for a longer time than usual?
