Smart robots may help children when they are recovering (恢复) from long-term illnesses in the hospital or at home. Those sick children may feel lonely without their classmates or friends around. Then the robots take the place of them at school. Through the robots, the children can hear what their teachers and friends say. More importantly, they feel less lonely while they are not at school.
A company made this kind of robot. It is called AVI. AVI goes to school for a child who is unable to leave home. And the child’s classmates must help the robot. They carry the robot between classes and put the robot on the child’s desk. It’s not difficult. At home, the child uses a computer or a phone to start the robot. Then the child uses the same computer or phone to control (控制) the robot. At school , the robot becomes the eyes,ears and mouth of the child. The best part is that the child can even join in classroom activities. The robot has speakers, microphones and cameras. Those things make communication easy.
AVI looks like a person. Scientists say this is important. The robot should be a friend of children. It can’t just be a small camera or let someone put it in a place. With AVI’s help, people think that children who can’t go to school will feel happier while they are at home.

【导语】本文主要讲了一种名为AVI的智能机器人可以代替因病无法上学的孩子去学校,通过远程控制让孩子参与课堂活动,从而减轻他们的孤独感。
26.推理判断题。根据“A company made this kind of robot. It is called AVI. AVI goes to school for a child who is unable to leave home.”可知,AVI是为因病无法上学的孩子设计的。C项中汤姆因脚受伤不能上学,可能需要AVI的帮助。故选C。
27.词句猜测题。根据“Those sick children may feel lonely without their classmates or friends around. Then the robots take the place of them at school.”可知,“them”指代前文的“那些生病的孩子”。故选A。
28.主旨大意题。第二段详细介绍了AVI如何工作:由同学搬运、孩子远程控制、参与课堂活动等,主要说明AVI如何帮助生病的孩子。故选B。
29.细节理解题。根据“…the child’s classmates must help the robot. They carry the robot between classes and put the robot on the child’s desk. It’s not difficult.”可知,同学们在课间休息时搬运机器人并放在桌上,这对他们来说并不困难,因此机器人AVI对学生们来说是易于搬运的。故选A。
30.主旨大意题。全文围绕AVI帮助因病缺席的孩子通过远程参与课堂来减轻孤独感展开,因此核心是“AVI能帮助一些孩子减少孤独”。故选C。
