1 . 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, loop and travel through time in a machine? What if we could go wherever and whenever we pleased?
This ability would allow us to witness historic wonders, change decisions and see people from the past. We could right wrongs and stop wars from starting.
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. This math tries to make the dream of time travel come true.
The scientist Albert Einstein said that time and space are one thing. He called it “spacetime.” Einstein said that 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 is a famous scientist. He 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.

2 . Want to get your package delivered via robots? Now there’s an app for that. If you live in Washington D.C., or Redwood, you may have glimpsed a small, boxy robot rolling along a local sidewalk, minding its own business, but attracting the attention of many curious onlookers.
The autonomous machines were part of a pilot program last year by Starship Technologies focusing on delivering meals from local restaurants in dozens of cities around the world. This week, the company unveiled plans to broaden its delivery service beyond food to include package, a move that led it to declare itself “the world’s first robot package delivery service”. The next time you order food, this cute robot might roll up to deliver it. The package delivery service is not available to everyone yet.
The wheeled robots have a top speed of 4mph and can detect obstacles from 30 feet away. “The robot can operate through anything,” Nick Handrick, head of operations for Starship’s D.C. office, sad, “If you had something in the way-a stick –it’s able to climb sticks.”
To sign up for the service, which costs a little more than $10 per month, customers need to download the company’s app. Customers then create a “Starship Delivery Address”, a unique address inside a Starship facility, where they can have package sent from places such as Amazon.com. Once a package is delivered to the Starship address, customers receive a text notification that allows them to schedule a home delivery via robot. The robots are opened by customers via a mobile phone code.
Barriers exist for robotic ground delivery, with many states requiring that humans be in control of delivery robots. Those regulations haven’t stopped Starship Technologies from accumulating experience on streets around the globe ahead of the company’s latest launch. The company says its robots have covered more than 125,000 miles in more than 100 cities in 20 countries.

3 . Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and younglooking. In 2035, medical technology is better than ever. Many people at your age could live to 150, so at 40, you're not old at all. And your parents just had an antiaging (抗衰老的) treatment. Now, all three of you look the same age!
You say to your shirt, "Turn red." It changes from blue to red. In 2035, "smart clothes" contain particles (粒子) much smaller than the cells in your body. The particles can be programmed (编程) to change your clothes' color or pattern.
You walk into the kitchen. You pick up the milk, but a voice says, "You shouldn't drink that!" Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.
It's time to go to work. In 2035, cars drive themselves. Just tell your "smart car" where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology" is all around you.
So will all these things come true? "For new technology to succeed," says scientist Andrew Zolli, "It has to be so much better that it replaces what we have already." The Internet is one example—what will be the next?

I often imagine what my life will be like in the future._______________________________
__________________________________________________________________________
I visited my aunt in a countryside near the city last week. I was surprising to see that great changes had been taken place in the countryside. Take my aunt’s family for example. We supply preciously trees and flowers to the stores in the cities and have over ten workers working for themselves. Their family’s income reached as much 100,000 yuan last year. Not only did they have a house, a car and computers, they can also afford a trip abroad every year. When asking what else they needed most, they said that they wanted to learn a few English so that they could do business with foreigners directly. To their delighted, my cousin can use that he has learned from university to help them with overseas trade.
7 . Let us suppose it is now about A.D. 2060. Let’s make believe (假设;虚构) it is about sixty years from now. Of course, things have changed and life is very different.
Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air-conditioned, naturally. In order that everyone can enjoy the beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is provided for entertainment (娱乐) of young and old.
What are people eating now? People are still eating food. They haven’t yet started to take on heir (继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many foods now come in pill form, and the food that goes into the pill continues to come mainly from green plants.
Since there are several times as many people in the world today as there were a hundred years ago, most of our planet’s surface has to be filled. The deserts are irrigated with water and crops are no longer destroyed by pests. The harvest is always good.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible to run the farm by just pushing a few buttons now and then.
People are now largely vegetarians (素食者). You see, as the number of people increases, the number of animals decreases. Therefore, the people have to be vegetarians and we are healthier both in our bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get rid of diseases. No one has to be ill any more.
Such would be our life in 2060.
