Article: Most cultures have a feast or festival of light. Each culture celebrates this festival in a different way. The Jewish Festival of Light is called Hanukkah. It usually takes place in December. The story of why Hanukkah is celebrated is very old. It is told that a long time ago, Jewish people called the Macabees were at war with a country called Syria. On the day that the Macabees won the war, they cleaned up their holy place, which is called a temple, because the Syrian people had been living there. They wanted to light their holy lamps to say thank you for the end of the year, but found only a very small amount of oil left over to do that. The Macabees lit the lamps anyway, thinking that they would soon go out. The lamps kept burning for eight days! The Jewish people celebrate Hanukkah every year by lighting a candlestick that has eight candleholders. Every night a new candle is lit so that on the eighth night, all eight candles stand together. Presents are given at this time and money is given to the poor. The Christmas story is not quite as old as the Hanukkah story, but it is also very old. Christmas is the time when Christians around the world celebrate the birth of Jesus Christ. It is believed that Christ was born in a stable. On the night of his birth, angels, shepherds and three wise men visited him. The wise men brought gifts with them. This is a happy and busy time of the year. Homes are decorated with Christmas trees and decorations. It is a time for being with the family. Families travel long distances to gather at Christmas. Lots of lights are put up everywhere. This is to show that Jesus is the"Light of the world"who came to bring peace to all people. Lanterns are another form of light. In China, the Lantern Festival goes back to the Han Dynasty. One emperor heard that Buddhist monks would light lanterns to _ Buddha on the 15th day of the 1st lunar month;so he also ordered to light lanterns in the imperial palace and temples to show respect to Buddha on the day. Later, the rite developed into a grand festival among common people. During the festival, parks become a sea of lanterns. Sometimes streets are blocked off and lanterns are put down on each side to make a hallway of lanterns. People also hang lanterns in their gardens, outside their houses or on boats. It is believed that the lanterns will guide visitors and the spirits of ancestors to the celebrations. The Lantern Festival is a time for families to reunite.

Despite the different languages, travel across Europe has never been so simple. Just five years ago, if you wanted to visit Germany in the north and Spain in the south in one trip, you had to wait for weeks to apply for different visas from the two countries. You also needed a calculator because both countries had different money. Today, with a Schengen Visa issued by any member country, you can travel across 15 European countries without stopping. Since 2002, within most of the EU, there is now just one type of money called the Euro. The Euro was designed to be the only money in the EU, and already makes it easier to shop around. If you drive, your driving license and car insurance policy are valid in the other European countries. And you can use your mobile phone everywhere. All the countries in the continent are melting into a united Europe under the EU. For Europeans and visitors, the result is that it is more convenient to travel back and forth between the different countries.

Article: By now, we are all aware that social media has had a tremendous influence on our culture, in business, on the world-at-large. Social media websites revolutionized the way people communicate and socialize on the Web. However, aside from seeing your friends' new baby on Facebook, or reading about Justin Bieber's latest conflict with the law on Twitter, what are some of the real influences? Social networks offer the opportunity for people to re-connect with their old friends and acquaintances, make new friends, share ideas and pictures, and many other activities. Users can keep pace with the latest global and local developments, and participate in campaigns and activities of their choice. Professionals use social media sites like LinkedIn to enhance their career and business development. Students can work together with their peers to improve their academic and communication skills. Unfortunately, there are a few downsides too to social networking. If you are not careful, immoral people can target you for cyber bullying and disturbance on social sites. School children, young girls, and women can fall victim to online attacks which can create tension and suffering. If you are a victim of cyber bullying, do not take it lying down, but try to take appropriate legal action against the attacker. Many companies have blocked social networks as addicted employees can distract themselves on such sites, instead of focusing on work.

Also, what you carelessly post on the Net can come back to trouble you. Revealing( ) personal information on social sites can make users vulnerable to crimes like identity theft, stalking, etc. Many companies perform a background check on the Web before hiring an employee.

The same holds true for our relationships too, as our loved ones and friends may get to know if we post something undesirable on social networks. Social media has its advantages and drawbacks as each coin has two sides. It is up to each user to use social sites wisely to enhance their professional and social life, and exercise caution to ensure they do not fall victim to online dangers.
