What picture do you have of the future? Will life in the future be better, worse or the same as now? What do you hope about the future?
Futurologists (未来学家) predict that life will probably be very different in 2050 in all the fields of activity, from entertainment to technology. First of all, it seems that TV channels will have disappeared by 2050. Instead, people will choose a program from a 'menu' and a computer will send the program directly to the television. By 2050, music, films, programs, newspapers and books will come to us by computer.
In what concerns the environment, water will have become one of our most serious problems. Demand for water will increase ten times between now and 2050 and there could be serious shortages. Some futurologists predict that water could be the cause of war if we don't act now.
In transport, cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed of the cars and there won't be any accidents. Today many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination.
In the domain of technology, robots will have replaced people in factories. Many factories already use robots. Big companies prefer robots—they do not ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.
Last but not least, medicine technology will have conquered many diseases. Today scientists have discovered how to control genes. They have already produced clones of animals. By 2050, scientists will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. Scientists will be able to do these things—but should they?
We were on our way home from Houston one Saturday morning. We decided to stop at a local gas station to get coffee and something to snack on since it was a good hour and a half before we got home.
When we were done, we got back into our car and before I started it, we noticed a man standing outside in front of the building. He was a homeless man with worn clothes and it looked like he had gone in and gotten himself some coffee or something warm to drink since it was cold this time of the year. He must have not had enough money to get something to eat.
Then a dog walked up to the front of the building. I could tell she was a "she", because you could tell that she had baby dogs. She was terribly in need of something to eat and I felt so bad for her. I knew if she didn't eat soon, she and her baby dogs would not make it.
I and my wife sat there and looked at her. We noticed that people walked by and didn't even pet her, like most people do when they walk by an animal in front of a store. We still did not do anything. But the homeless man, who I thought did not buy himself anything to eat, went back into the store. And what he did brought tears to me and my wife. He had gone into the store and with what money he may have had, bought a can of dog food and fed that dog.
This story plays a great part in our lives. You see, that was Mother's Day weekend. And a lot of people forget that some animals are parents too.
It took a homeless man, to show me what I should have done. He made me a better man that day.
The new model is the highly interactive (互动的) learning model. We could also call it the conversational model, or the tutorial model. It is computer based, with the interaction between the students, or a small group of students, and learning programs are like the conversation between a student and a skilled tutor. Distance learning will be the main delivery method.
Student interaction with the learning material on the computer will use the student's natural language; it will seem like a conversation between a student and a human tutor. This is the key point of highly interactive, or conversational, learning units. Programs will ask questions in the student's native language, and respond reasonably to free-form student input. Multiple choice and pointing will seldom be used; they often do not allow individualization (个体化) of education.
An important aspect of this model is that the computer will frequently store information about the student, about problems and about how far individual students have progressed. These records will be used often within the programs. Thus when a student returns to the learning activity, the computer knows about that student and knows where to begin the new part.
Global education is critical for the future, to get rid of poverty, corruption (腐败), violence and war, to solve major problems such as the lack of drinkable water, and to insure a happy life for all. Education should no longer be limited to the wealthy of the world, but should be available to everyone.
In the new distance learning environment, learning can take place in markets, libraries, public buildings, learning centers, and homes. Gradually schools and universities will play a smaller role in learning, both because better learning can be delivered through such highly interactive material, and because such learning will be less costly for the individual student. Motivation (动机)is particularly important in a mastery-based distance learning, as the usual threats of traditional classrooms such as that of low grades are no longer possible.
Voice input will probably be the mode for this interaction. The new voice input systems from several companies are useful, cheap, and speaker independent in highly interactive learning. Keyboards may not be needed. Speech is a natural way for humans to communicate.
Students will work in small peer groups, about four. Other contacts with people, learning circles, will be possible, directly or electronically.
One of the most efficient ways to achieve peace and speed up economies (经济) is to provide girls with better education and more rights. Today, girls' lack of access (进入) to basic education is getting more serious when it comes to the use of digital (数码的) technology, leaving them far behind boys. And because the world is even more digital, those who lack basic internet skills will find it increasingly more difficult to take part in the formal economy, to get a quality education, and to have their voices heard.
Since 2013 the global gender gap (性别差异) in male and female access to the Internet has actually increased from 11 to 12 percent. Worse yet, women and girls living in the poorest countries are 31 percent less likely than men and boys to have access to the Internet. In developing countries, some 200 million fewer women than men own a mobile phone, the most common means of Internet access there. This digital divide is increasing, and should it continue at the present pace, it is projected that over 75 percent of women and girls will lack Internet access and digital skills.
There are many causes of the digital gender gap. They include girls' exclusion (排斥) from basic education, from specific technology education and high costs of mobile phones and Internet access.
Indeed, one of the so-called reasons why girls may be discouraged from learning how to access and use digital technology is also a groundless one—that girls are simply not good at using technology.
Without the help of the government, most of the benefits of technological change will be enjoyed only by men, exacerbating gender inequality.
How to Ensure Safety During a Holiday?
Start by selecting the right airline—you can check out a list of all airlines around the world and their safety records on the Aviation Safety Network. Selecting the right airline is a vital first step.
Bear in mind that there will be general panic and other people will try to reach it as well.
In an emergency evacuation, you must leave all personal belongings behind. Carry-on bags will slow your exit and create a hazard for you and others.
Don't wait for others to move; many will be overcome by fear.
Put together a comprehensive first aid kit to take with you and make sure it is tailored to the environments in which you are going to be travelling.
When you first arrive at your hotel be sure to keep your luggage with you at all times. Many people have their luggage stolen when checking in or checking out of their hotel.
Keep your wits about you and watch out for people standing too close or who appear to be listening in on your conversations. If they see you later on in the restaurant or by the pool, they will know your room is unoccupied.
Never accept a room on the ground floor, as these are the easiest for criminals from outside to break into.
A. That way you will know exactly what's in it and where to find each item.
B. If travelling alone in a taxi, always sit directly behind the driver.
C. Get yourself out regardless of what others are doing.
D. Make yourself familiar with your nearest exit and make it clear how you will get there in an emergency.
E. Don't rely on the hotel staff to keep it safe.
F. They might be trying to find out which room you are in and whether you are travelling alone.
G. As soon as you check into your room, test that the door lock and the deadlock are working.
Years ago when I volunteered at a homeless shelter, I talked with a boy, Albert. He said he liked my1. "Do you want to see mine?" he said,2his leg. He was barefoot. He said he'd been meaning to pick up a pair but hadn't gotten one. I felt a3feeling in my stomach.
A few days later I was at home helping to4my daughter. I smiled when I5the socks over her feet. At that moment, Albert flashed in my6.
At noon, I went to a department store and7a shopping cart with socks—nothing8, just white cotton men's socks.
The next morning, I drove to the Palisades Park, which is a common overnight destination for9individuals. I grabbed one of the10from my trunk and walked across the grass. It was dark out. It was a beautiful feeling to11before the sun and most living things.
I headed for a group of three men. Two were asleep and the third was digging through his shopping cart. It was loaded with plastic bottles and some clothes, and a few books—most12, everything he owned in this world. As I walked toward him, he turned and13me, perhaps questioning my intention.
"I thought you might14some new socks," I told him, handing him a pair. He looked15at first but took them, smiled and said, "Thank you." I gave two more16for his partners.

"Remember, your father is only one year (old) than you." That was Mum's usual excuse when Dad said the wrong things or did something (fool).
Dad quitted drinking exactly one year before I was born. He joined a group of other people. He said they (stop) drinking, too. I loved my dad I hated the way his weekly meetings took him away me. It seemed that they were more (importance) to him than I was. But with my birthday coming up I thought Dad would make an exception. "Can't you miss it just this time? Saturday is my birthday!" I begged him but (refuse). He said "I am chairing the meeting this Saturday. We will have your party on Sunday."
Saturday evening I sat on my bed, (feel) sorry for myself. Dad started to leave, then paused and said, "Why not come with me together tonight? It's an open meeting. All are welcome." would I do at a meeting? But maybe I needed to see why something Dad did every week mattered so much.
After we arrived, Dad announced the theme of the meeting was going to be gratitude. He told his story about giving up smoking. Later, a man(call) Dave also told his story. Only then did I know it was Dad that saved his life from drinking. Showing up week after week and meeting with people, Dad was changing lives. Shame washed over me.

My sister saw a lovely cup when we are shopping the other day. She liked it at once. Then she bent down and picked up to look at a price on it. As she did this, lots of tea splashed on his T-shirt! I had to try hardly not to laugh at her shocked face! My sister wanted go out of the shop as fast as she could when a shop assistant came over to us. It was turned out to be her own cup, that she'd left on the shelf by mistake. The assistant was clearly as embarrassing as my sister, for I just thought it was funny!
