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.

The journey to the moon has been the first step toward future exploration(探险) in space. The distance between the moon and the earth is very short indeed when compared with the distances between the earth and the other planets. Mars, one of the nearest planets to the earth, is millions of miles away. Travelling to the planets will be mans next aim. Such travels will be more challenging than the trip to the moon and certainly more adventurous.
Recently, two American spaceships, Vikings 1 and 2 landed on Mars trying to discover whether there is any life on the planet. So far the signs of life on Mars has neither confirmed nor ruled out.(排除)
Russians have discovered that the surface of Venus（金星）is so hot that it is almost certain that there is no life there. Also the atmosphere of Venus is extremely dense and the pressure is nearly a hundred times greater than that of the earth’s atmosphere.
Scientists believe man may find planets which have the same conditions as those we have on the earth, but man should realize the earth will be his only home for a long time and begin to love and care about it.

5 . In the near future, IoT (Internet of Things) will drive huge innovation (革新) in the way our food is grown. Plants will have a “voice”, not a human voice, but a voice based on data that can tell people, computers, and machines when, for example, they are thirsty, or need more sun, medicine, etc.
Take vertical (垂直的) farms, for example. Farming is moving indoors where the growth of plants can be monitored and controlled. The facilities are built vertically, so growing areas can be put in piles. This greatly reduces the amount of land needed for farming.
From an IoT point of view, vertical farms are connected in two ways. First, small sensors (传感器) in the soil or connected to plants tell a control system exactly how much light, water, and nutrients are needed to grow the healthiest crops. Sensors will also tell vertical farmers when crops are nearing their peak for harvesting at just the right time to make sure it’s still fresh when it reaches its final destination.
Second, vertical farms will be connected to other networks and information systems, including databases that track local demand. For example, local restaurants may input when they need fresh food supplies. And vertical farmers could get that information so they know which crops to grow in what quantities. This type of IoT system would have been unimaginable a generation ago.
Today, vertical farms are being experimented. Yet, the numbers point to a bright future for the industry, especially as the world’s population continues to grow. For example, Green Sense Farms in Chicago is able to harvest crops 26 times a year using 85 percent less energy, one-tenth the water, and no pesticides. A side benefit of lower energy use is lower CO2 output of two tons per month, with the added benefit of creating 46 pounds of oxygen every day.

8 . 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.

9 . 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.

10 . Imagine being face-to-face with a woolly mammoth (猛犸象) . It would be quite a sight. Scientists believe it would tower above 11 feet tall and have a sloping back, a long, powerful trunk, and sharp, curved tusks that stretch up to 10 feet. Its thick hair would be up to three feet long. It would weigh six tons—about as heavy as a bus.
You’ve probably never seen a giant furry elephant before. Actually, you definitely haven’t. The species has been extinct for thousands of years.
But a few years from now, you might be able to see a woolly mammoth in person. Scientists believe they have the technology to recreate it.
A team of South Korean and Russian scientists plan to clone a woolly mammoth. How will they do it?
Several woolly mammoth bodies have already been discovered in Siberia, an icy region in Russia. The scientists plan to take cells from these frozen mammoths. In a laboratory, they’ll use them to create a new cluster (群) of cells called an embryo. The embryo will be placed into the womb of a living female elephant. That elephant will then give birth to a baby woolly mammoth.
The scientists believe the whole process will take five years. Many scientists and animal lovers can’t wait. It will be so exciting to be able to bring a creature that has been extinct for thousands of years back to life. People would travel from around the world for the chance to see a living woolly mammoth. By observing the way the creature looks and acts, scientists might make brand-new discoveries about the history of animal life.
Other experts aren’t so sure about the woolly mammoth project. One big question is what to do with a mammoth. The Earth has changed in the thousands of years since these animals roamed the planet. Where would the creature live, and would it be able to survive in today’s climate ? Some believe that the money being spent on the experiment could be better spent on other important scientific projects, such as fighting diseases.
But the South Korean and Russian scientists are sticking to their plan. They admit they have a big challenge ahead. There is no guarantee that they will succeed, but they’ re hopeful.
