Steve Jobs, co-founder and former CEO of US technology giant Apple, has died at the age of 56. Mr Jobs had announced he was suffering from cancer in 2004. Apple said he had been "the source of countless innovations（创新）that enrich and improve all of our lives" and had made the world "immeasurably（无法衡量的）better".
Tributes(赞美之辞) have been made by technology company bosses and world leaders, with US President Barack Obama saying the world had "lost a visionary（有远见卓识的人）". "Steve was among the greatest of American innovators —— brave enough to think differently, bold enough to believe he could change the world, and talented enough to do it," said Mr Obama.
A statement from Mr Jobs's family said they were with him when he died peacefully on Wednesday. "In his public life, Steve was known as a visionary; in his private life, he loved his family deeply," they said, requesting privacy and thanking those who had "shared their wishes and prayers" during his final year.
Apple said the company had "lost a visionary and creative genius(天才) and the world have lost an amazing human being". Tim Cook, who was made Apple's CEO after Mr Jobs stood down in August, said his predecessor had left behind "a company that only he could have built, and his spirit will forever be the foundation of Apple". Flags are being flown at half mast outside the Apple headquarters（总部） in Cupertino, California, while fans of the company have left tributes outside Apple shops around the world.
The heads of other leading technology companies have also paid tribute, including Microsoft boss Bill Gates, who said "For those of us lucky enough to get to work with him, it's been a great honour. I will miss Steve very much."
Facebook founder Mark Zuckerberg thanks Mr Jobs for "showing that what you build can change the world" while Sony Corp president and CEO Howard Stringer said: "The digital age has lost its leading light." South Korea's Samsung, which is involved in a case with Apple over patents(专利), admired Mr Jobs for his "Completely new and different changes to the IT industry".

　　Dear Mr Heppell,

　　I am Sabrina Akhtar studying in a high school and I've noticed that forests are disappearing(消失).

　　You know, forests are disappearing around the world each year. This is because of many different reasons including farming, tourisms pollution(污染), etc. If we stop doing these things, there will be a good future for people of tomorrow.

　　Now I'm writing to ask you to help stop forests from disappearing. You can help by getting shops to stop selling paper made from trees and changing to tree-free paper(paper not made from trees). This will help forests so much. There are many, many things we can do to help forests. If you would like to know more, please visit http://www.Rainforestweb.org/. By changing the little things, we can make a big difference.

　　If you would like to contact me, please see the above address or e-mail me at shazadinol@hotmail.co.uk.  Thank you for taking your time in reading this letter.

　　Yours sincerely,

　　Sabrina Akhtar
