     A cancer-stricken British teenage girl said Thursday she had been moved by messages of

support from around the world after writing an online "Bucket List" of things she wanted to do

before dying.

     Alice Pyne, l5, created an Internet blog in which she described her fight against a cancer of

the white blood cells. " I've been fighting cancer for almost four years and now l know that the

cancer is gaining on me and it doesn't look like I'm going to win this one," she wrote.

     For her list, the teenager took inspiration from the 2007 film "The Bucket List", in which two

terminally ill (患绝症的) men, played by Morgan Freeman and Jack Nicholson, draw up a list

of things they wish to do before they die.

up to be a bone marrow donor (骨髓捐赠者), swimming with sharks, meeting boy band Take

That and getting a purple iPad computer.

most talked about subjects on Twitter.

     "Oh dear and I thought that I was just doing a little blog for a few friends!" she wrote after her

site attracted huge attention. "Thank you so much for all your lovely messages to me."

     Pyne, who lives with her family in the northwest English town of Ulverston, revealed (透露) the
