BE A GOOD TOURIST

Tourism can be both good and bad. Yes, it brings in money for the local economy and creates lots of jobs for locals, but it may also bring some problems.

Tourists have used paint, rocks, or even keys to write on the Luxor Temple in Egypt, the Colosseum in Rome, Stonehenge in the UK, memorial stones at the bottom of Qomolangma, and many, many other-places. Thousands of tourists sites are being destroyed by tourists who "love them to death". If you want to leave a mark on the world, do it by changing someone's life with kindness and love Pass kindness along to future generations, not destruction.

Another big problem in some places has been tourists disturbing the local people and For example, Chiang Mai University in Thailand and Yonsei University in South Korea have great numbers of tourists visiting their campuses and walking through their libraries and other public areas, taking pictures of students and disturbing their studies. I have three words for tourists like this: please be considerate.

The number of problems from tourists is endless: walking in large groups without considering others who need to walk by, crossing roads without observing local traffic laws, and many more. The only way to solve the issue of the terrible tourist is to make sure that you are not one! Remember, whenever you step outside your country's borders, you are representing your country to the rest of the world.

A. Just think from other aspects

B. When in Rome do as the Romans do.

C. Have fun in a way that does not disturb others

D. Be the best, kindest, most polite tourist possible

E. I have three words for people like this: please stop it.

F. One growing problem is tourists who want to prove that they have visited someplace

G. Some tourists wander around and take pictures of local people without asking for their permission.

The Amazing Spider Man

    Spider Man is a hero. People got to know the hero through the Spider Man movie series.

    Now, a new Spider Man movie is coming to our eyes. It has a new name called The Amazing Spider Man. A new director called Marc Webbis directed the movie and a new actor, Andrew Garfield, played Spider Man.

    The Amazing Spider Man is also about the story of Peter Parker, a high school student. His parents left him when he was a boy, and he was raised by his Uncle Ben and Aunt May. Like most teenagers, Peter is trying to figure out who he is and how he got to be the person he is today.

    As Peter finds a briefcase that belonged to his father, he begins to find out why his parents disappeared. The discovery of his father's secret will shape his destiny(命运)of becoming “Spider Man.”Peter will make his choices to use his powers and become a hero.

    Unlike the former one, the new movie focuses on Spider Man developing his abilities in high school, as well as discovering the mystery(秘密)of his parents, or at least what happened to his father.

    The movie is going to come out on July 3, 2012 in 3D.
