1.  Read the passage and finish the exercises.

Today, robots come in all shapes and sizes. They can't complain, even if the work is heavy and dangerous. And they can work or play all day without getting bored. Unlike a human's arms, a robot's joints will never get stiff(僵硬的). The end of the arm can be fitted with devices(装置)to perform different tasks. Such an arm of these computer controlled industrial robots can work 24hours a day.

Robot pets are high-tech robots programmed to play. They can communicate with their owners and recognize their voices. Each one will develop a different "personality". They can be a lot of fun to play with, and they can also be helpful to people who are sick and can't look after a real animal. Many doctors believe that when a person is happy and laughing, their body recovers faster. A robot pet might be just what the doctor ordered.

NeCoRo is a robot cat that has been developed to be more than a toy. The robot uses sensors(传感器)that can detect movement and sound. It can even store helpful information in its memory. Its behavior changes over time, just like a real pet
