As the audience got larger, thetechnology got better. Television sets became more reliable through the 1960s. The reception (接收效果)improved. The picture improved. The major networks started broadcastingprograms in color.

    Even greater improvements were comingaccording to Sanford Brown, who wrote an article for the Post in 1967.Surprisingly, just about every prediction he made in the article became areality. For example: All sets in the not-distant future will be colorinstruments. He also predicted that TV sets would become smaller, simpler, morereliable and less expensive and may forever put the TV repairman out of work.Smaller sets do not, of course, mean smaller screens. TV engineers expectscreens to get much bigger. However, today's 3-D TV is even farther away, if it's coming at all. There is some doubt whether the public would be eager topay for it, in view of people's cold reception given to 3-D movies.

    But the technology with the greatestpotential, according to Brown, was cable television (有线电视), whichwas still in its early stages then. As he predicted, the future of cabletelevision was highly interactive (互动的). It wasn't cable television that gaveAmericans their electronic connection to the world, however. It was theInternet. He even foresaw the future office: using picture phones, big-screentelevisions for conferences, and computers providing information at the touchof a button.

    Brown ever said, “The future oftelevision is no longer a question of what we can invent. It's a question ofwhat we want.”

    For those who are tired doing the laundry, Samsung has found an answer: a washing machine that can tell you when your laundry is done via a smartphone app(application).

    Strange though it may seem — “my wife already does that” was a common response among attendees viewing the device when it was introduced at the Consumer Electronics Show (CES) this week — Samsung is just one of many appliance makers racing to install (安装) a large number of internet-connected features in machines in an effort to make them “smart”.

    Last year, it was a refrigerator that tweeted. This year, it's Wi-Fi-enabled laundry machines and fridges that can tell you when your groceries are going bad.

    The washers and dryers, available starting in the spring, connect to any smartphone through a downloadable application. The phone can then be used as a remote control, so the machines can be turned on and off while their owners are at work or on the bus.

    Samsung says it's not just something new — the app connection actually has some practical uses.

     “If you started to dry clothes in the morning and forgot to take them out, you can go to your phone and restart your dryer for the time when come home, so your clothes are refreshed and ready to go,” said spokesperson Amy Schmidt.

    The company also says that with electricity rate(电价)varying depending on the time of day, more control over when the machines are used can help save money.

    Perhaps, but what they will probably really accomplish is what all good technologies do —enable laziness. Rather than getting up to check on whether the laundry is done, users will instead monitor it on their phones while watching TV.

    The Maldives faces the threat of extinction from rising sea levels, but the government said on Thursday it was looking to the future with plans to build homes and a golf course that can float.

An increase in sea levels of just 18 to 59 centimeters would make the Maldives — a nation of a number of tiny coral islands in the Indian Ocean — not suitable for humans to live in by 2100, the UN's climate change experts have warned.

    President Mohamed Nasheed has declared a fight for survival, and last month he signed a deal with a Dutch company to study suggestions for a floating structure that could support a conference centre, homes and an 18-hole golf course.

    The company, Dutch Docklands, is currently building floating developments in the Netherlands and Dubai. Its website said it undertook projects that make “land from water by providing large-scale floating constructions to create similar conditions as on land”.

    The Maldives began to work on an artificial island known as the Hulhumale near the crowded capital island of Male in 1997 and more than 30,000 people have been settled there in order to ease crowdedness. The city, which has a population of 100,000, is already protected from rising sea levels by a 30-million-dollar sea wall, and the government is considering increasingly imaginative ways to fight climate change.

    Nasheed, who held the world's first underwater cabinet (内阁) meeting in October to highlight his people's serious and difficult situation, has even spoken of buying land elsewhere in the world to enable Maldivians to relocate if their homes are completely covered.

    He has also promised to turn his nation into a model for the rest of the world by becoming “carbon neutral (碳中和)” by 2020. His plan involves ending fossil fuel use and powering all vehicles and buildings from “green” sources such as burning coconut husks.

    In the summer of 1848, in Guatemala, a man called Ambrosio Tut went out into the jungle, as he did almost every day. Tut was a gum collector, looking for gum in the jungle. To do this, he had to climb the trees. One day, he got to the top of one tree and something caught his eye. He looked out across the trees and saw the tops of some old buildings.

    Tut didn't really know what he had seen but he knew it was something special. He ran to tell the local governor excitedly, and together they walked into the jungle. There they found Tikal, the city that the Mayans had built, many hundreds of years before. The two men saw pyramids, squares and houses.

    For a long time before that day, local people had known that somewhere in the jungle there was an old Mayan city. But no one had seen it for centuries. Between 200 and 900 AD, the city of Tikal had ben the centre of Mayan civilisation in the area, but then the Mayas let it—nobody knows why! After 1000 AD, the jungle began to cover it. And then people forgot that it was there.

    Seven years before Tut found Tikal, two British explorers had gone to Guatemala and had written a report about Mayan treasures in the jungle—but they hadn't mentioned Tikal. Even earlier than this, local Indians had told people about a great city hidden in the trees, but no one had listened to them. So they lost the chance to find the treasure. Now the lost city had been found again, and people went there immediately to see it.

    Knowing a little first aid could be life-saving if you see someone lying unconscious.

    Too often people don't do anything because they think they will kill the patient, but by learning simple rules you could make the difference between life and death.

    First, you need to find out if they're unconscious, asleep or drunk, by squeezing the skin between their neck and shoulder and shouting. If there is no response at all, you need to establish if they are dead or just unconscious—sometimes it's very difficult to tell the difference.

    Open the airway by placing one hand on their forehead and gently tilting the head back while lifting the chin.

    If there are no signs of life—no obvious pulse and their chest is not going up and down—call an ambulance and then start cardiopulmonary resuscitation (CPR) (心脏复苏) to maintain (获得) a flow of oxygenated blood to the brain and heart.

    Do this by pushing up and down on the centre of the chest, with your hands interlocked together, constantly until an ambulance arrives.

    Push at a rate of 100 beats a minute. You can't harm them doing this and might just save a life.

    There are many places to go on safari (观赏野生动物) in Africa, but riding a horse through the flooded waters of Botswana's Okavango Delta must rank as one of the world's most exciting wildlife journeys.

    Several safari camps operate as the base for this adventure, providing unique rides twice a day to explore deep into the delta. The camps have excellent horses, professional guides and lots of support workers. They have a reputation for providing a great riding experience.

    The morning ride, when the guides take you to beautiful, shallow lakes full of water lilies, tends to be more active. It is unlike any other riding experience. With rainbows forming in the splashing water around you and the sound of huge drops of water bouncing off your body and face, it is truly exciting. You are very likely to come across large wild animals, too. On horseback it is possible to get quite close to elephants, giraffes and many other animals. The sense of excitement and tension levels rise suddenly though, as does your heart rate, as you move closer to them.

    In the evening, rides are usually at a more relaxed and unhurried pace, with golden light streaming across the grassy delta and the animals coming out to eat and drink. Sedate though they are, rides at this time of day are still very impressive. As the sun's rays pass through the dust kicked up by the horses, the romance of Africa comes to life.

    Back at the camp you can kick off your boots and enjoy excellent food and wine. Looking back on your day, you will find it hard to deny that a horseback safari is as close as you will ever come to answering the call of the wild.
