1 . “May 17, 2157
Dear diary,
Today, Tommy found a real book!...”
“What’s it about?” Margie asked.
“School.” replied Tommy, turning the yellow pages.
“Why would anyone write about school? I hope they can take my geography teacher away.”
“It’s not our school. This is the old sort that they had centuries ago.”
“Anyway, they had a teacher.” Margie said, reading the book over his shoulder.
“Sure, they had a teacher, but it wasn’t a regular teacher. It was a man.”
“A man? How could a man be a teacher?”
“Well, he just told the boys and girls things and gave them assignments and asked them questions.”
“A man isn’t smart enough.”
“Sure, he is. My father knows as much as my teacher.”
Margie wasn’t prepared to argue about that. She said, “I wouldn’t want a strange man in my house to teach me.”
Tommy laughed. “The teachers didn’t live in the house. They had a special building and all the kids went there.”
“And all the kids learned the same thing?”
“Sure, if they were the same age.”
“But my mother says a teacher has to be adjusted to fit the mind of each boy and girl it teaches and that each kid has to be taught differently.”
“If you don’t like it, you don’t have to read the book.”
“I didn’t say I didn’t like it,” Margie said quickly.
They weren’t even half-finished when Margie’s mother called, “Margie! School!”
“Not yet, Mamma.”
“Now!” said Mrs. Jones.
Margie said to Tommy, “Can I read the book some more with you after school?”
“Maybe,” Tommy said.
Margie went into the schoolroom, right next to her bedroom, and the mechanical teacher was on waiting for her.
The screen was lit up, and it said, “Please insert yesterday’s assignments in the proper slot.”
Margie was still thinking about the old schools they had when her grandfather’s grandfather was a little boy. All the kids from the whole neighborhood came, laughing and shouting in the schoolyard, sitting together in the schoolroom, going home together at the end of the day. They learned the same things, so they could help one another on the assignments and discussed them.
And the teachers were people…

I have seen amazing things.
My first visit was to a space station considered the most modern in space. Described as an enormous round plate, it spins slowly in space to imitate the pull of the earth’s gravity. Inside was an exhibition of the most up-to-date inventions of the 31st century. A guide showed us around along a moveable path.
Guide: Good morning to all our visitors from 2008. First we’re going to examine one of the latest forms of communication among our space citizens! Messages can now be sent using a “thoughtpad”. You place the metal band over your head, clear your mind, press the sending button, think your message and the next instant it’s sent. It’s stored on the “thoughtpad” of the receiver. It’s quick, efficient and environmentally friendly. The only limitation is if the user does not think his or her message clearly, an unclear message may be sent. But we cannot blame the tools for the faults of the user, can we?
During the explanation I looked at the pair of small objects called “thoughtpad” on a table. They just looked like metal ribbon. So ordinary but so powerful! While I was observing them, the path moved us on.
Guide: And now ladies and gentlemen, we are in the “environment area”. People used to collect waste in dustbins. Then the rubbish was sent to be buried or burned, am I right?（We nodded.）Well, now there’s a system where the waste is disposed of using the principles of ecology. A giant machine, always greedy for more, swallows all the waste available. The rubbish is turned into several grades of useful material, such as “fertilizer” for the fields and “soil” for deserts. Nothing is wasted, and everything, even plastic bags is recycled. A great idea, isn’t it?
I stared at the moving of the waste machine, absorbed by its efficiency. But again we moved on.
Part 1
Our third stop shows the changes that have happened to work practices. Manufacturing no longer takes place on earth but on space stations like this one.

5 . Government intelligence agencies have a plan to build computers that store information inside DNA and other organic molecules（分子）.
Intelligence Advanced Research Projects Activity（IARPA）announced plans to develop tabletop-sized machines that can store and retrieve（取回）data from large batches of polymers — a term that refers to a wide variety of long，string-like molecules. Polymers can store data in individual atoms or groups of atoms.
The project is an attempt to solve a basic problem of the modern era:the vast and growing costs of data storage. Datacenters around the world sucked up 416. 2 terawatt hours of electricity in 2016. That's about 3 percent of the global supply，and it accounts for 2 percent of global greenhouse gas emissions.
A 2016 paper found that DNA，in particular，could store computer information more densely，require less energy，and survive higher and lower temperatures than conventional hard drives. The authors of that paper reported on the successes of prototype（雏形）DNA computers that used the genetic molecules for both long-term storage and random access memory（RAM）.
But no one has yet figured out how to handle DNA data storage on large scales.
IARPA officials said the new effort, called Molecular Information Storage, will be broken up into three periods:a two-year program to figure out how to store data in DNA or other molecules at high speed,a two-year program to figure out how to retrieve that data at high speed, and a two-year effort to develop an operating system that can run on that DNA.
Many of the technologies IARPA wants to develop are untested at these scales, so it's unclear how far away that proposed tabletop device really is.

6 . From self-driving cars to carebots for elderly people，the rapid development in technology has long represented a possible threat（威胁）to many jobs normally performed by people. But experts now believe that almost 50 percent of occupations（职业）existing today will be completely unnecessary by 2025 as artificial intelligence（AI）continues to change businesses.
“The next fifteen years will see a change in how we work，and a change will necessarily take place in how we plan and think about workplaces，”said Peter Andrew，director of Workplace Strategy for CBRE Asia Pacific. A growing number of jobs in the future will require creative intelligence，social skills and the ability to use artificial intelligence.
The report is based on interviews with 200 experts，business leaders and young people from Asia Pacific，Europe and North America. It shows that in the US technology already destroys more jobs than it creates. But the report states，“Losing occupations does not necessarily mean losing jobs—just changing what people do.”Growth in new jobs could occur as much，according to the research.“The growth of companies that have the speed and technological knowledge will directly challenge big companies，”it states.
A report by Pew Research Center found 52 percent of experts in artificial intelligence and robotics were optimistic about the future and believed there would still be enough jobs in the next few years.“The optimists pictured a future in which robots do not take the place of more jobs than they create，”according to Aaron Smith，the report’s co-author.
“Technology will continue to affect jobs，but more jobs seem likely to be created. Although there have always been people out of work，when we reach a few billion people there will be billions of jobs. There is no shortage of things that need to be done and that will not change，”Microsoft’s Jonathan Grudin told researchers.

7 . The United Arab Emirates (UAE) is mostly a desert. However, this has not stopped the country from creating great building projects. On September 26, UAE officials announced another ambitious project — Mars Science City. Expansive deserts and miles of coastline provide plenty of options for safe rocket launches (发射). And its position on the Earth makes it especially appealing as the spin of the Earth provides an extra push, meaning less fuel is needed to get payloads into orbit. All these seem to make it possible.
The Mars City Project, designed by Bjarke Ingels Group, or BIG, will provide a realistic model to simulate (模仿) living on the surface of Mars, the red planet. It is part of the UAE’s Mars 2117 Project to lead the global race to land humans on Mars and be the first to build a settlement there. Sheikh Mohammed bin Rashid, Prime Minister and ruler of Dubai, says, “The UAE seeks international support to develop technologies that benefit humans, and lay the foundation of a better future for more generations to come.”
Built outside Dubai, the 1.9 million square feet city is expected to cost $135 million. It will consist of several dome-shaped laboratories, similar to the ones imagined for the first Mars settlers. Scientists from around the word will be invited to conduct research to come up with methods to create food, water and energy, using techniques which can be copied onto the red planet. The living spaces, where the researchers can live for up to a year, will simulate the planet’s conditions as much as possible.
The research city will also include a museum featuring famous space achievements to help educate and inspire children to undertake space exploration and discovery. To discover whether the construction method works on Mars, the museum’s walls will be 3D printed using the sand from the nearby desert. Now, if they would only add some living quarters for the general public to experience life on Mars without leaving Earth, life would be perfect.
