After a year at sea, 16-year-old Laura Dekker can finally say, "Mission accomplished！"Last month, she finished a daring trip around the world aboard her 38-foot boat, Guppy. Dekker, who is from the Netherlands, traveled more than 30,000 miles all by herself. She is the youngest person ever to sail around the globe alone.

Dekker had wanted to take on this challenge when she was even younger. She first tried to set sail at the age of 13, but a court in the Netherlands stopped her. They said that she was too young to make such a risky trip by herself. But Dekker insisted she had the navigation skills and patience of an adult sailor.

She finally started on August 21, 2010. During her trip, Dekker battled loneliness, storms, and worries about pirates. But she also got to surf, scuba dive, and started a new hobby: playing the flute. Although Dekker didn't spend all of her time at sea—she stopped at ports along the way—she did spend her 16th birthday on the open ocean. To celebrate, she ate doughnuts for breakfast.

But Dekker didn't sail into the record books. Guinness World Record and the World Sailing Speed Record Council no longer recognize records for "youngest" sailors. They dropped the category in 2009 to discourage children from attempting such dangerous feats(壮举). But that didn't stop Dekker, who was born on a yacht(大游艇) during a seven-year world voyage undertaken by her parents.

Dekker doesn't mind that she won't hold an official record. She says it was a personal goal, and she is happy she achieved it.

"I am not disappointed at all that Guinness World Records won't recognize my attempt, "Dekker wrote on her website, "I did not start on my trip to achieve any record. I did it just for myself."

I'm a booklover but like sharing my love for books！So I've been bought books constantly. Finishing reading one book，I placed it in my school so that some of my schoolmate can enjoy themselves when reading it. I especial like placing it on a stone table in the little garden that students might have time to take a rest. I was delighted when I saw the card left on the table to say thanks the other day. And from the card，I knew my book turned out of to be a birthday gift for a strange girl. It was so lovely find out that my book could bring anyone pleasure！
