题目列表(包括答案和解析)
Children can spend hours a day looking at computer screens and other digital devices. Some eye doctors say this leads to an increase in “computer vision syndrome(电脑视力综合症).”
Nathan Bonilla-Warford is an optometrist(验光师)in Tampa, Florida. He has seen an increase in problems in children. “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried,” he says.
Dr. Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or the computer or whatever taken away,” he explains.
He says another part of the problem is that people blink(眨眼)less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And so that can result in the front part of the eye drying and not staying protected like normal.”[来源:Z.xx.k.Com]
Eye doctors offer suggestions like following which is known as the 20/20/20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you’re using.
Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.
But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, from Children’s Hospital Boston, has not seen an increase in his practice. “While it is possible to develop fatigue looking at screens for a long period of time, there’s certainly no proof that it actually causes any damage(伤害)to the eyes.” he says.

What might the future be like? Here are some predictions(预言).
Returning home during the Spring Festival is difficult for many Chinese people. More than 2 billion people travel at the same time, making buying travel tickets and the journey difficult. But 28 years later, Spring Festival travel may not be a problem at all. China plans to build more railways and a fast transportation network that will serve 90% of the population by 2020. And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem.
Oil is running out faster than expected. But scientists have found something else for oil as fuel(燃料). Coal, natural gas, sun power, nuclear power(核能) and even water can take the place of oil as energy.

Life in 30 years will be 31 because many changes will take place, but what will the changes be?
The population is growing fast. There will be 32 people in the world and most of them will live longer than before. Computers will be 33 smaller and more useful, and there will be at least one in every home. And computer studies will be one of the important 34 in school.
People will work fewer hours than they are doing now, and they will have more free time for sports, watching TV and traveling. Traveling will be much cheaper and 35 . And more people will go to other countries 36 holidays.
There will be changes in our food, too. More land will be used for 37 new towns and houses. Then there will be less 38 for cows and sheep, so meat will be more expensive. Maybe people won’t eat it every day, they will eat more vegetables and fruit instead. Maybe people will be healthier.

Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet.
Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it. Technology will change the way we learn; schools will change as well; and we will learn something from the Internet.
