题目

阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。Recovering strength andmovement after an injury often involves physical therapy(治疗). Physical therapists help patients with brainor bone injuries regain control of their muscles. Exercising muscles plays animportant part in the restoration process. Therapists use balls and boards toimprove balance, stretchy bands to increase strength and other exercises.But a Polish technologycompany Egzotech has developed a robot called Luna, to make those exercisesinteractive. Luna can help therapists choose the best exercises for their patients.The robot also provides therapists with information about their patients'progress.Luna uses electromyography,or EMG, to identify electrical currents as patients bendtheir arms or legs.Michal Mikulski is the chief executive officer of Egzotech. He saysdetectingmuscle tension not immediately visible to the human eye can help therapistsdesignbetter exercises."We reach a certainstage of disease development when the muscle tension is not even visible. Butthese signals can still be seen on our machines. Luna is still able to detectthem. And based on that, when the brain sends a signal to the muscle to flex(紧绷), even though we don't see it, Luna is stillable to detect it. It detects these signals and causes the movement of the limb(肢), as if it were performed naturally."Luna can also make therapyfun for children who often get bored with repeated movements. Luna permits themto play games without knowing that they are exercising their muscles."Sometimes it is a spacecraft,sometimes shooting balls, sometimes flying a dragon. In, any case, a childwants to win a game, wants to compete, but in fact they are exercising."Luna is just an originalmodel. But Egzotech expects to have other robots ready for sale later this year. （1） What's the function of paragraph l? A . To introduce the topic of the text. B . To explain how exercising muscles works.
