( A )My grandfather was a teacher. He was the headmaster of a school for boys 1 the age of thirteen and eighteen. He was very strict with the boys but kind 2 , because when I was young , he usually gave me nice things, told me interesting stories. But I believe that the boys at his school were 3 of him.At school, when he 4 a room full of noisy boys, there was 5 at once. When he looked at a boy, that boy 6 red in the face, and looked down at his shoes. If a boy didnt do his homework 7 and brought him his poor and careless work, my grandfather would pick up the boys book and threw it 8 the room, shouting, “Do it again and bring back tomorrow morning!” If the boy forgot to bring the work with him 9 time, he had to do it again and again, and yet again. My grandfather worked hard all his life. All the students had their love for him 10 they left his school.( )1. A. of B. between C. at D. by( )2.

One day while he was walking in the street, he felt 4 and went into a restaurant. When the waiter came, the Englishman 5 his mouth, put his fingers into it and took them out again and moved his lips.

And some do simple jobs.When an automatic（自动的）washing machine 2 , water goes in. The machine waits until the water is hot 3 washing the clothes. It does this by “feedback”（反馈）. Information about whats happening is “feed back” into the robot to tell it 4 next.Our eyes, ears and other senses（感官）are our feedback. They tell us 5 around us. So robots are like people in 6 ways. They work and they have feedback.But 7 robots look like people. Many are hidden away. Robots control the temperature of our house, our cookers, our hot water systems. We can set the controls to the temperature we want. The robot does 8 . Its feedback usually come from a thermostat（自动调温器）.One kind of thermostat is strip of metal, which bends（弯曲）when it gets hot. At the right temperature, it bends just enough 9 a switch. This turns off the heat. As the air around it gets 10 , the metal gets straight, and this turns the heat on again.( )1.
