5 . One day, you might be ordering your favorite pizza from a robot.Researchers at a university in Pittsburgh, Pennsylvania, are working on creating a pizza-making robot.
“Robots are basically preprogrammed to repeat the same actions over and over,” says David Held, a robot expert from Carnegie Mellon University, and one of the members of a pizza-making team.But making pizza has challenges.For instance, the flour (面粉) will become squishy when meeting water, with a shape that can change in many ways.Also, pizza-making requires many steps—such as rolling and cutting—and several tools, including a rolling, a knife and so on.In what order should the steps be done? Which tools should be picked, and when? “If you need to do a cooking task, there are several levels that you have to reason about,” Held says.Once people get the hang of it, “We don’t even need to think about exactly how we’re doing it- it sort of just happens.But robots can’t really “understand what to do on their own”.
To start, the team used a computer to consider how a robot could lift, fatten, gather, move and cut dough (生面团).The method has two levels of robotic reasoning: one that thinks how it should approach the overall task, and the other that thinks how it should move its “hands” to perform each action.The result was better than with the usual programming techniques.“We got a little bit closer to the right shape than the former methods,” Held says.“‘But there’s still a lot of room for improvement.”
For now, people will continue to make pizza the old-fashioned way: with their own hands.Sill, a pizza-making robot is a good goal.And if a robot could deal with dough, it could also work with other objects that can change shapes.“You can imagine robots helping in hospitals, or robots that clean up toys in day cares,” Held says.“The general goal is to eventually have robots that can help with whatever the task may be.”
1. What does the underlined word “squishy” in paragraph 2 mean?A.Soft. | B.Dirty. | C.Plain. | D.Precious. |
A.Separating flour from water. |
B.Doing all the steps in order. |
C.Using several tools at once. |
D.Repeating the same actions. |
A.Methods of moving a pizza. |
B.Problems with pizza making. |
C.Improvements to the pizza robot. |
D.Suggestions on how to make pizza. |
A.They will help humans in different fields. |
B.They will replace humans to do all the work. |
C.They will do better than humans in day cares. |
D.They will do whatever task as well as humans. |

7 . Life will probably be very different in 2050. First of all, it seems that TV channels will have vanished by 2050. Instead, people will choose a programme from a “menu” and a computer will send the programme directly to the television. By 2050, music, films, programmes, newspapers and books will come to us in the similar way.
In many places, agriculture is developing quickly and people are growing fruit and vegetables for export. This uses a lot of water. Therefore, there could be serious shortages of water. Some scientist predict that water could be the cause of wars if we don’t act now.
In the future, cars will run on new, clean fuels (燃料) and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Also, by 2050, space planes will fly people from Los Angeles to Tokyo in just two hours.
Some big companies now prefer to use robots that do not ask for pay rises or go on strike, and work 24 hours a day. They are also easy to control. And they never argue with people. They can be easily used in a variety of places — factories, schools, offices, hospitals, shops and homes.
Scientists will have discovered how to control genes (基因). Scientists have already produced clones (克隆) of animals. By 2050, scientists will be able to produce clones of people and decide how they look and how they behave. Scientists will be able to do these things, but should they?
1. Which of the following best explains “vanished” underlined in paragraph 1?A.Settled. | B.Spread. | C.Disappeared. | D.Decreased. |
A.Robots can work in different places. |
B.Robots have much to be improved. |
C.Robots work for humans for free. |
D.Robots have many advantages. |
A.He probably disagrees with the idea of human cloning. |
B.He is looking forward to using of cloning technology. |
C.The scientists have already discovered how to control genes. |
D.The scientists will face many difficulties of controlling genes. |
A.High-tech Cars | B.Life in the Future |

10 . What is the future of AI (人工智能)? Will it be a good thing? We asked four students what they think.
Liu Lei | I think AI will be more useful in our future lives. It’s now used in many fields, like phones and medicine. No one really knows what will happen if machines become smarter than humans. However, I’m sure AI will help us solve many problems. |
Xu Lu | I’m worried that people create something that can be better than themselves. In the near future, AI will develop at a high speed. Humans may be replaced (取代) because AI robots will do a lot of work instead of people. |
Zhao Mingming | I really think that Al will change the way we work, the way we live, and the way we think. Imagine if we could put a CPU into our brains! Soon we’ll be able to improve our math and memory. How exciting! |
Molly | Think of what’s happening now. Some robots are used to kill animals. So I think AI will be very dangerous for humans, too. We need to be careful about what we ask machines to do. |
A.Because humans are smarter than AI. |
B.Because AI robots will do lots of human jobs. |
C.Because humans will put a CPU into our brains. |
D.Because we can’t improve our math and memory. |
A.AI will be more useful for people. | B.AI will be less useful for people. |
C.AI will be dangerous for people. | D.AI will be important for people. |
A.Liu Lei and Xu Lu | B.Liu Lei and Zhao Mingming |
C.Xu Lu and Molly | D.Zhao Mingming and Molly |
