Nowadays, we can find robots easily around us. Some do very complicated jobs like flying airplanes and driving subway trains. Others do simple and tiring jobs. When an automatic ( 自動(dòng) 的 )washing machine is turned on, water pours in. The machine waits until the water is warm enough for washing clothes. It does this by “feedback”( 反 饋 ). Information about what is happening is feedback into the robot to tell what to do next. Our eyes, ears and other senses are our feedback. They tell us what is going on around us. So robots are like human beings in two ways. They work and they have feedback.

In some ways robots are better than human beings. They work quickly and do not make mistakes. They do not get bored doing the same job over and over again. And they never get tired. So robots are very useful in factories. They can be taught to do many different jobs. But some people show their worries that robots will take the place of human beings. 500 men and 500 women are interviewed about their worries.

1.In what ways are robots like humans?

2.What are the advantages(優(yōu)點(diǎn)) of robots? (at least two examples)

3.How many men showed their worries about robots in the interview?

4.What percent of people worry that there may be fewer chances for people?

5.Do you think robots will be able to take humans place? Why or why not?

When I was a little child, my mom sometimes liked to make breakfast food for dinner. And I remember one night she made breakfast after a long hard day at work.

That evening, my mom placed a plate of eggs, sausage and very burned (完全烤焦的) cookies in front of my dad. I remembered waiting to see if anyone would say anything. But all my dad did was to reach for his cookie, smile at my mom and ask me how my day was at school. I didn't remember what I told him that night. But I did remember watching him eat bite of that cookie!

When I got up from the table that evening, I remembered hearing my mom say sorry to my dad for burning the cookies. And I'll never forget what he said, “Dear, I love burned cookies.”

Late that night, I went to kiss Dad goodnight. And I asked him if he really did like his cookies burned. He gave me a big hug and said, “Your mom had a hard day at work today, and she's very tired. Besides, a little burned cookie never hurt anyone!”
