　　A

　　Located in Pisa, the Leaning Tower of Pisa in Italy has become the sign of Italy. It is the third oldest structure in Pisa's Cathedral Square. There eight floors in the Leaning Tower of Pisa including observation deck at the top. The weight of the tower is about 14,500 metric tons. There are amazing facts of the Leaning Tower of Pisa that we will mention here.

　　The Leaning Tower of Pisa was not originally intended to lean, but because it was built on soft soils the tower gradually leaned to one side. Prior to its restoration(修复) from 1990 to 2001, the tower had a tilt(倾斜) of 5.5 degrees. Many people think that it will fall one day. Millions of tourists come to the lawns around the tower to take the classic photo pretending to hold up or knock down the tower.

　　It is said that you must visit the Leaning Tower of Pisa during the day. At night the shops are closed and it appears unimpressive. But, if you plan to visit on a full moon night, the tower will look charming. Mornings are the best time to beat the crowds. Summer in Pisa is very hot and wet, but you can expect rain in fall and winter.

　　Even though some people regard the tower to be an engineering failure owing to the tilt, the tower has acquired a special place in history. The tower has also been used for experiments by the famous Italian scientist named Galileo Galilei. He is believed to have thrown two balls of different mass from the tower to prove that their falling time is not related to their mass.

　　Now many young people are travelling around the world on their own, not because they have no one to travel with, but because they prefer to go alone.

　　Kristina Wegscheider from California first travelled alone when she was at college and believed that it was something everyone should do at least once in their life. She said, "It opens your mind to new things and pushes you out of your comfort zone." Wegscheider has visited 46 countries covering all seven continents.

In foreign countries, with no one to help you read a map, look after you if you get ill, or lend you money if your wallet is stolen, it is challenging. This is what drives young people to travel alone. It is seen as character building and a chance to prove that they can
