IV. 阅读理解:

Farris Hassan, a 16-year-old high school student from Florida, decided to visit Iraq and left for the country on December 11th, 2005 alone, without having informed his parents.

After catching a connecting flight in Amsterdam, he arrived in Kuwait City on December 13th. He called his parents on the telephone and informed them of where he was and his intention to visit Iraq. This was the first time his parents learned of his plans. He then attempted to cross the Kuwait –Iraq border by taxi, because of tight security for the upcoming elections he was unable to pass though and spent a week in Beirut, Lebanon. Then on December 25th, he flew to Baghadad International Airport. Relatives picked him up from the airport and put him at a hotel known to frequently house American citizens.

He paid for the trip and made all the arrangements himself with money that he had saved up. The inspiration for his journey was the result of attending a class on “step into journalism” at his school. He was working on an assignment on the war in Iraq and he wished to experience his subject matter first-hand.

Hassan’s parents were born in Iraq, but he does not speak any Arabic, making him easily stand out as a foreigner in Iraq, where kidnappings(绑架)of Americans and violence are an everyday occurrence. His parents planned to take him to see Iraq once the war was over.

He turned in his assignment via e-mail and was due to be back home over the New Year’s Day weekend.
