A famous building in New York City is turning 100 years old. A year-long celebration is planned for Grand Central Terminal, which is usually called Grand Central station, the sixth most-visited place in the world.

The huge building has not changed much since it opened in February, 1913. About 750,000 people pass through Grand Central every day. Some just come to look at it, others to visit the stores. But most are there to catch the trains that enter and leave from the station. It is the largest train station in the world. There are 67 train tracks, all of them underground.

The main part of the building has large, arched windows, a jeweled four-sided clock and ticket windows. Grand Central has been seen in many movies through the years. Dan Brucker is with the New York Transit Authority, which operates the station. Dan Brucker has worked for the transit authority at Grand Central for 30 years. In all those years, he has not lost his interest in the building.

Justin Ferate, a historian, has been giving tours of Grand Central Station for 30 years. He says the station was designed to make travel a pleasure.

“Why people don't run into each other in Grand Central is simple: each block of stone in Grand Central is the length of your leg. Each block of stone in Grand Central is the length of your arm. Each block of stone is a different color, so it’s a checkerboard, based on you.”   

A ten-year-long fight against plans to build a huge office building over Grand Central in 1968 helped create the modern preservation（保护） movement. Now, no one would think of changing the beauty of the station.

The San Diego Zoo has been a lovely home for giant pandas since two of the black-and-white bears came to visit in 1987. This week there was snow in San Diego—well, at least for a lucky group of giant pandas.
Over 15 tons of snow was blown into the San Diego Zoo's panda area on Tuesday morning to give the endangered bears a chance to play. They would experience the snow just like living in their natural habitat.
The snow day was a first for Xiao Liwu whose name means "Little Gift." He was the sixth baby panda born to Bai Yun. Xiao Liwu was jumping on Mom, playing with her and getting used to being thrown in the snow by mama bear. Jennifer Becerra, San Diego Zoo keeper said, "He was really enjoying the snow and running around. I've never seen him so happy."
All the San Diego Zoo’s giant pandas are from China, as part of a long-term captive breeding(人工养殖) program. Four of Xiao Liwu's brothers have already been moved from California to China.
Today there are 44 giant pandas living in zoos outside of China, where the bears' only natural home is. As just 1,600 pandas are thought to be left in the wild, researchers insist that captive breeding is an important way to study and protect the endangered pandas. Not only because of the habitat loss from human activities and low reproductive rates(繁殖率), giant pandas' survival is also affected by climate change. A study showed that global warming could kill much of the bears' main food, bamboo, over the next century.
