1 . Who has no regrets about things done in the past? Wouldn’t it be nice if, somehow, we could go back to change a couple of bad decisions? This sounds like science fiction.
The laws of physics prohibit traveling back in time for many reasons. If we did travel back in time and changed the course of events, we would be altering the course of history. An example often cited is the grandfather’s paradox (悖论): If your grandfather died when he was still a high school student, he wouldn’t have met your grandmother and your father and you wouldn’t exist.
Putting humans or consciousness traveling back in time aside for the moment, is there anything in science even similar? Surprisingly, yes. At the level of quantum particles (量子粒子), there is something called Wheeler’s delayed-choice experiments that show that actions in the present can influence the past. The experiments use something called the wave-particle duality (波粒二象性) of light and of matter. The fact that the physical nature of quantum objects is undetermined until it is measured. In other words, this means that a particle of light or of matter can behave either as a wave (spreading out in space) or as a particle (staying together) depending on the measuring devices. Long and ongoing discussions about the nature of quantum physics are still trying to work out what this actually means. Do our minds determine the nature of physical reality?
Should we offer food for thought for the future or the past? Unfortunately, these experiments say very little about how we could interfere with the past in events relevant to the human scale. Better to think carefully about decisions than to try to fix them backwards.

How will our continuously growing population affect our way of life, our environment, even our planet? No matter how you look at it, we will face
However,
3 . What will the future school look like is difficult to make clear, but most experts agree that the school will be electronic in the future.
“Present-day schools will no longer exist in the next century,” says a report in The Age. “At that time, future schools will become community-style centers, which run seven days a week, 24 hours a day.” At the same time,computers will surely become a central part of the school in the future.
According to The Age, the distant learning will be popular and students will listen to teachers on computers. Going into classrooms on their computers, students will study at any time, which is very easy for them. However, it is necessary for students to go to the actual school in order to develop some social skills.
The Seashore Primary School is an imaginary school in the future created by the Education Department of Australia. At this school, all the teachers and students have laptop computers. Teachers check messages and call students back on a special telephone system and students use telephones to search for information or speak to their experts who teach their lessons. Besides, all the lessons are related to all sorts of subjects and all the students have their own learning plans created by teachers.
As one headmaster says, a laptop computer is students' library. data storage as well as the bridge to a wider world. Technology has changed the emphasis of future learning. Thus, we'll pay more attention to the learning of kids rather than the teaching.

5 . What do you use your fridge for: It can not only keep your food cold, but also make ice and freeze food. But in the future smart fridges may do much more than you can think. They may tell you what food is inside, what food you need, what food is healthy for you, and even shop for you, too!
Some companies are making online fridges which have a computer screen on the door. And it can be very useful that the computer is linked to a supermarket through the Internet. For example, when you finish your orange juice, you can put the empty juice carton (纸盒包装) near the computer screen. The computer reads the bar code on the juice carton. Then it orders more orange juice from the supermarket. You can also use the computer screen to order other things from the supermarket. The computer screen has a series of things that are in the store. You can choose what you need. The supermarket will send the food to your home.
Companies are making other kinds of “smart” appliances (电器), too. There is a new kind of microwave oven (微波炉) which has a computer memory. It can remember 365 different cookbooks. There is also a smart mixer that can remember cookbooks. Even it can test ingredients for you!
Of course, sometimes these smart appliances don’t work. When they do, they will tell you. And then they can call someone to fix them, too!
1. Your fridges can do the following things except .A.keep food warm | B.make ice |

C.The mixer can test ingredients for you. |
D.The mixer can help you clean the kitchen. |
A.Online fridges have a computer screen on the door. |
B.Fridges of the future will order food from the supermarket. |
C.Smart appliances, like online fridges, can be very helpful. |
D.People won’t have to go to supermarkets to buy food in the future. |
6 . Up until a few decades ago, our expectation of the future were largely positive. Science and technology would cure all the ills of humanity, leading to lives of satisfaction and opportunity for all.
Now the utopia (乌托邦) has grown unfashionable, as we have gained deeper appreciation of the range of threats facing us, from natural disasters to deadly flu to climate change. You might even be tempted to assume that human beings have little future to look forward to.
But such negative attitude doesn’t make sense. The fossil record shows that many species have existed for millions of years- so why shouldn’t we? Take broader look at our species’ place in the universe, and it becomes clear that we have an excellent chance of surviving for tens, if not hundreds, of thousands of years.
So what does our deep future hold? Perhaps it may be easier to think about the question in long time periods than about the more immediate future. The potential evolution of today’s technology, and its social consequences, is astonishingly complicated, and it’s’ perhaps best left to science fiction writers and futurologists (未来学家) to explore the many possibilities we can merely imagine. That’s one reason why we have launched Arc, a new publication dedicated to the near future.
But take a longer view and there is a surprising amount that we can say with considerable assurance. As so often, the past holds the key to the future: we have now identified enough of the long-term patterns shaping the history of the planet, and our species, to make evidence-based forecasts about the situations in which our future generations will find themselves.
This makes the negative predictions of our future seem more likely to be temporary and unreliable. To be sure, the future is not all rosy. But we are now knowledgeable enough to reduce many of the risks that threatened the existence of earlier humans, and to prevent the lot of those to come.
1. What used to inspire our expectation of the future?A.Our desire for lives of satisfaction. |
B.Our faith in science and technology. |
C.Our awareness of potential risks. |
D.Our belief in equal opportunity. |
A.Are limits the range of futurological studies. |
B.Technology offers solutions to social problem. |
C.The interest in science fiction is on the rise. |
D.Our near future is comparatively hard to predict. |

9 .
News anchors(主播) must have been reluctant to read out the following news: Xin Xiaomeng began working as the world’s first female artificial(人工的) intelligence news anchor at Xinhua News Agency on Sunday, three months after a male robot joined the profession.
Unlike previous news robots though, Xin does not read news like a cold machine; she reads it almost like a human being. The muscles on her face stretch and relax-and her reactions change-as she continues reading. That’s why many news anchors were worried: Will AI replace us in the near future?
To find the answer, we have to analyse the technologies that support Xin at her job. Three key technologies are used to support Xin. First, samples of human voices are collected and synthesized (合成). This is followed by the collection and synthesis of human muscle movement samples. And third the voices and movements are married in a way that when the Al news anchor reads, the micro -electric motors behind her face move to make her expressions seem more human.
Yet we need a thorough knowledge of deep leaning technology to make a robot imitate a person’s voice. The developer needs to collect tens of thousands of pieces of pronunciations, input them Into the machine and match them with the text or the Al to lean and read. The process for imitating facial movements is similar. The developer has to analyse the movements of the 53 muscles in the human face, make a model set from the collected data for the AI news anchor to lean, and imitate the movements of facial muscles via programs
Both the technologies used to make Xin’s performance impressive are mature. The real difficulty lies in the third -the technology to match the pronunciations with facial movements so that Xin expressions vary according to the content of the news report. In fact, Xins expressions don' t always change according to the content. As a result, her expressions look anything but human. Actually. AI is still no match for human qualities.
