While it may seem like everyone surfs the web these days, there is fine line between casually checking your social media pages and having a full blown Internet addiction. If you fear that you may lose interest in other aspects of your life because you prefer to be on the Internet, you may be on your way to an Internet addiction. {#blank#}1{#/blank#}

Admit you are at risk of an addiction.

    More and more people in the world are becoming addicted to the Internet. You are not the only one with this problem; it is becoming more and more common and more and more well known. {#blank#}2{#/blank#}.

Set aside limited time for computer use.

    Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed when you are not using it; {#blank#}3{#/blank#} If you have a desktop PC, try not to go near it or put something over it like a sheet.

Call people instead of sending instant messages or texts.

    If you are free on weekends, call friends and ask them to go outside. This will distract you from the computer. {#blank#}4{#/blank#}

Use an alarm clock or timer.

    Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get off the computer when the time is up. Alternatively create a shutdown timer on your desktop. {#blank#}5{#/blank#}.

A. Make a small list of what you want to do within that time.

B. When the computer is not looking at you, you are less likely to use it.

C. This can be programmed to shutdown your computer after the set time

D. Luckily, there are ways to avoid living your life in front of the computer.

E. This will stop you from using the Internet so often or going on to another page.

F. If you have a problem on weekdays, phone your friends or ask for help in person.

G. Do not be embarrassed; find others with the same problem and help each other beat it.

    In a natural disaster: a hurricane, flood, volcanic eruption, or other catastrophes. Minutes and even seconds of warning can make the difference between life and death. Because of this, scientists are working to use the latest technological advances to predict when and where disasters will happen. They are also studying how best to analyze and communicate this information once it is obtained.

    On September 29,1998, Hurricane Georges made landfall in Biloxi, Mississippi, after damaging Haiti, the Dominican Republic, Puerto Rico, and several islands of the Caribbean badly with heavy rains and winds up to 160 km per hour. Few people lost their lives along the Gulf Coast of the United States, although hundreds died in the Caribbean. This was a very different result, when a powerful Gulf Coast hurricane made an unexpected direct hit on Galveston, Texas, killing at least 6,000 people. Vastly improved hurricane warnings explain the different circumstances at either end of the 20th century—residents of Galveston had no advance warning that a storm was approaching, while residents of Biloxi had been warned days in advance, allowing for extensive safety precautions (预防).

    At the same time that people in Biloxi were thankful for the advance warning, some residents of New Orleans, Louisiana were less satisfied. A day before Georges made landfall, forecasters were predicting that the hurricane had a good chance of striking New Orleans. Emergency management officials must begin evacuations (疏散) well before a storm strikes. But evacuation costs money. The mayor of New Orleans estimated that his city's preparations for Georges cost more than 50 million. After Georges missed New Orleans, some residents questioned the value of the hurricane forecasts in the face of such high costs.

    The different views on the early warnings for Hurricane Georges show some of the complexities (复杂) related to predicting disasters. Disaster prediction is a process of providing scientific information to the government officials and other decision makers who must respond to those predictions.

    Hungary's capital sparkles(闪耀)in winter and it's a great place to see in the New Year. There's festive cheer on tap, with concerts, folk dancing and stalls selling wine or fruit brandy and traditional chimney cake outsides. New Year's Eve is celebrated with fireworks over the Danube(多瑙河), and it's worth booking one of the many river cruises(巡游)with dinner and DJs (free and open 24/7, but likely to be crowded).

    A four-night trip with Travel Republic costs £449 for a family (2 adults with 1 child under 6), departing Stansted on 28 December with Ryanair, with B&B accommodation at the central Atrium Budapest Hotel.

    For a slightly more cerebral(理智的)New Year's Eve, Stockholm is a smart choice. The main celebration is at Skansen, Sweden's oldest open-air museum. Enterainment starts at 8 p.m. with singing and dancing, and peaks with a recitation of the poem Ring Out. Evening tickets are £14 for adults (children under 6 go free), or there are new day and evening combination tickets (£16 adult/£5 child). On New Year's Day, early birds can try an introduction to ice skating (8 a.m. daily, £139).

    Book it Ryanair, Norwegian and SAS fly to Stockholm from several UK airports.

    The land of fire and ice lives up to its name on New Year's Eve, when about 90 bonfires(篝火)are lit across the country. Some bonfires are accompanied by Icelandic singing; most start about 8 p.m. and finish by 10 p.m., which can be a good time to see the northern lights. After the fires, everyone goes home to watch Áramótaskaup, a TV show that has been running on 31 December since 1966. But that doesn't mean the party is over just before midnight, they all come back out to let off an astonishing amount of fireworks, with profits going to Icelandic Search and Rescue Association, which does life-saving work, and is run by volunteers and is a cause close to most Icelanders' hearts.

    Book it Wow Air and Wizz Air, easyJet and Icelandair fly to Reykjavik from several UK cities.

    When a leafy plant is under attack, it doesn't sit quietly. Back in 1983, two scientists, Jack Schultz and Ian Baldwin, reported that young maple trees getting bitten by insects send out a particular smell that neighboring plants can get. These chemicals come from the injured parts of the plant and seem to be an alarm. What the plants pump through the air is a mixture of chemicals known as volatile organic compounds, VOCs for short.

    Scientists have found that all kinds of plants give out VOCs when being attacked. It's a plant's way of crying out. But is anyone listening? Apparently. Because we can watch the neighbors react.

    Some plants pump out smelly chemicals to keep insects away. But others do double duty. They pump out perfumes designed to attract different insects who are natural enemies to the attackers. Once they arrive, the tables are turned. The attacker who was lunching now becomes lunch.

    In study after study, it appears that these chemical conversations help the neighbors. The damage is usually more serious on the first plant, but the neighbors, relatively speaking, stay safer because they heard the alarm and knew what to do.

    Does this mean that plants talk to each other? Scientists don't know. Maybe the first plant just made a cry of pain or was sending a message to its own branches, and so, in effect, was talking to itself. Perhaps the neighbors just happened to "overhear" the cry. So information was exchanged, but it wasn't a true, intentional back and forth.

    Charles Darwin, over 150 years ago, imagined a world far busier, noisier and more intimate (亲密的) than the world we can see and hear. Our senses are weak. There's a whole lot going on.

    The earliest known copy of Leonardo da Vinci's Mona Lisa—thought to have been painted at the same time as the original masterpiece—has been discovered at the Prado Museum in Madrid, Spain. The work offers art-lovers an attractive clue to what the model for the world's most famous painting really looked like. Controllers of the museum found the picture hidden beneath layers of paints during restoration work on a picture initially thought to have been a later replica(exact copy) of the Mona Lisa.

    The restored version shows the same woman that Leonardo depicted (描画), against a landscape similar to that shown in the background of the original, which now hangs in the Louvre in Paris. And while the features of Leonardo's Mona Lisa have been dulled by centuries of dirt and layers of cracked paints—which are unlikely ever to be removed—in the recently-rediscovered copy, she appears fresher-faced and younger than her better-known "twin".

    News of the find was revealed at a meeting at London's National Gallery, linked to its "Leonardo da Vinci: Painter at the Court of Milan" exhibition. "This sensational (轰动的) find will transform our understanding of the world's most famous picture," the Art Newspaper reported, adding that the clues found on the Madrid version suggest that the original and the copy were begun at the same time and painted next to each other, as the work went on.

    Miguel Falomir, manager of Italian painting at the Prado, told reporters that expert analysis suggested a strong link between Leonardo and the artist who painted the copy. "The painting was done in the painter's own workshop," he said. "It is absolutely consistent with Leonardo's work, but Leonardo didn't actually do any work on it himself."
