3 . What if we had the power to control time, instead of moving from the past to the present to the future? What if we could jump and travel through time in a machine? What if we could go wherever and whenever we pleased?
The mysterious puzzle of time has kept people debating its nature for hundreds of years. Science fiction writers have turned it into imaginative stories. Some scientists have even attempted to explain it using math, trying to make the dream of time travel come true.
Albert Einstein said that time and space are one thing called “spacetime.” He said there are three dimensions in space: height, width and depth. A scientist named Hermann Minkowski added time as a fourth dimension.
Einstein introduced two ideas that have led to theories about the possibility of time travel. The first is relativity. The idea of relativity is that the force of gravity causes space to bend, which causes time to twist. The second idea focuses on special relativity. The idea is that a traveler moving super-fast through flat spacetime will enter the future. Einstein considered time “relative” because it is measured based on where we are on Earth or in space.
Stephen Hawking believes that a time machine will never be built. If it were possible, he thinks we would already know. If a time machine could be built, how come no one from the future has invaded us?
The first science fiction story with this theme is The Clock That Went Backward by Edward P. Mitchell, which was published in 1881. Since then, thousands of books, films and television shows have explored the idea of time travel, in which some tools such as phones, watches, photographs and old books take travelers backward and forward.
Will time travel ever happen? Who knows? Most important is to keep your eyes open and have a sense of wonder.
1. What is the author’s purpose of writing the first paragraph?| A．To show time and space are connected. |
| B．To show people’s interest in time travel. |
| C．To draw readers’ attention to time travel. |
| D．To make people believe time travel is possible. |
| A．Time travel is possible in the future. |
| B．People can’t move faster than light. |
| C．Time travel is against scientific rules. |
| D．Spacetime is not a real thing in theory. |
| A．The first science fiction story. | B．Different works about time travel. |
| C．Edward P. Mitchell, the pioneer. | D．Some tools used in time travel. |
| A．Negative. | B．Approving. |
| C．Doubtful. | D．Hopeful. |
4 . If you think of the jobs that robots could never do, you would probably put doctors and teachers atop of the list. It’s easy to imagine robots and factory workers. But are we underestimating what robots can do?
In some cases, they already do better than doctors at diagnosing illness. Also, some patients might feel more comfortable sharing personal information with a machine than a person. Could there be a place for robots in education after all?
British education expert Anthony Seldom thinks so. He even has a date for the robot takeover of the classroom:2027. He forecasts that robots will do the main job of disseminating knowledge and teachers will be like helpers. Intelligent robots will read students’ faces, movements and even brain signals. Then they will pass the information on to each student in the way he or she can understand.
However, it’s not a popular opinion. Most people think it’s impossible that robots will have the ability to really connect with humans like another human can.
One thing is certain, though. A robot teacher is better than no teacher at all. In some parts of the world, there aren’t enough teachers and 9%-16% of children under the age of 14 don’t go to school. That problem could be partly solved by robots because the owners can teach anywhere.
Being a teacher is a difficult job and teachers often feel overworked. Perhaps the question is not “Will robots replace teachers?” but “How can’t robots help teachers?” Teachers spend a lot of time doing non-teaching work, including more than 1 hour a week marking homework. If robots could cut the time teachers spend marking homework and writing reports, teachers would have more time and energy for the parts of the job humans do best.

5 . Ever since the beginning of human civilization, we are trying to reduce manual efforts by making simple to extremely complex machines. The next step in the same process is robotics and automation. Robotics and automation is a field with abundant potential. It expands its scope from household applications to solving mysteries of the Universe to curing untreatable medical conditions.
Up until the beginning of 2020, robots of any kind are made up of nor-living materials. Recently scientists from the University of Vermont & Tufts University introduced Xenobots, which have opened a whole new Universe for this field. Xenobots are the world’s first living and self-healing microbots. These robots are designed with the help of computer-generated- evolutionary algorithm(算法). The living cells used for its creation are skin, heart and stem cell from the African frog embryos(胚胎).
These microbots are very basic in nature, made up entirely from the organic substance. They can move forward, turn around, spin in circles and flip over. They are smaller than a millimetre and can travel inside the human body. Just imagine the possibilities we will have, once scientist is able to teach Xenobots to do the desired task. One day they even might be able to fight cancer cells. They will be able to clear microplastics in the oceans and lots more.
But if these bots are a life form, why are we calling them robots? This is because scientists are designing them to move or work according to their wills. A certain arrangement for skin and heart cells in an Xenobot will make it move in a straight line, while a different arrangement of the same cells will be required to move them in circular motions.
Xenobots are positively a great step. Scientists are also calling them a brand new life form on the planet. The future is unseen but is undoubtedly full of countless possibilities.

7 . In 2015, a man named Nigel Richards memorized 386, 000 words in the entire French Scrabble Dictionary in just nine weeks. However, he does not speak French. Richards’ impressive feat is a useful example to show how artificial intelligence works — real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field.
The potential applications for AI are extremely exciting. Because AI can outperform humans at routine tasks — provided the task is in one field with a lot of data — it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.
But not every job will be replaced by AI. In fact, four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the complex, strategic jobs — executives, diplomats, economists — go well beyond the AI limitation of single-field and Big Data. Then there are the as-yet-unknown jobs that will be created by AI.
Are you worried that these three types of jobs won’t employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require compassion, trust and sympathy — which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children.
So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.

Each Solar Road Panel measures roughly 4 meters by 4 meters and contains a microprocessor (微处理器) that monitors and controls the panel, while communicating with neighboring panels and the vehicles traveling overhead. The inventors suggest that this provides a communications device every 4 meters on every road which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems. The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions (抓地力)
According to the inventors, the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop, or at any business that has paved Solar Road Panels in their parking lots.
The inventors say their Solar Roadway has many functions and advantages from main roads to driveways, parking lots, bike paths, sidewalks and runways. The Federal Highway Administration has given Brusaw ＄100,000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring .
