In 1901, the citizens of Colorado Springs in the USA decided to collect everyday items and to seal (密封) them in a steel box. The box was marked “To be opened after midnight, December 31st , AD2000”, and was stored in the Colorado College library.
One hundred years later, on the appointed day, 300 people gathered to watch the opening of the box. Many in the crowd were the descendants (后代) of people who had placed things inside the box.
When the box was opened after midnight, the contents were in very good condition. There were newspapers, photographs, diaries, name cards, family trees, books and dozens of letters, including one written by Theodore Roosevelt, who became the President of the USA later that year. One of Roosevelt's friends lived in Colorado Springs at that time.
Many of the letters were addressed to their descendants. They describe the hopes that people of 1901 had for the people of the next century. At that time, Colorado Springs had just a few thousand residents, Now nearly half a million people live there.
Colorado College Library has scanned the material and put them on a website. Cecil Muller, whose grandfather had placed a collection of postcards in the box, said that the time capsule was a great treasure. “This is a
wonderful educational resource. We can learn so much about our history,” he said. “I never knew my grandfather, but now I feel very close to him.” In April 2001, a committee filled the time capsule with items from modem Colorado Springs and resealed it for another hundred years. 81. According to the passage, when was the box opened? (no more than 5words) _____________________________
82. What did many of the letters in the box talk about? (no more than 5words) _______________________________.
83. What does the “time capsule” refer to according to the context in the passage? (no more than 12)
