     When we look to the east of Shanghai, we are sure to see a beautiful tower, especially in the evening

when the lights are on. That is the Oriental Pearl TV Tower.

     The Oriental Pearl TV Tower is 468 meters high, the tallest in Asia (亚洲) and the third in the world.

It weighs 125,000 tons. We know the weight of the Eiffel Tower in Paris is only 7,000 tons.

     The Oriental Pearl TV Tower can help broadcasting (广播) and TV transmission (转播). There are

six high-speed elevators (电梯) in the Tower. People can go up and have a beautiful view (视野) of

Shanghai.

     There are eleven steel (钢) balls in the Tower. They look like 11 beautiful "pearls" in the sky. The

lowest one is 68 meters high and the highest pearl is called the Space Cabin. It is 343 meters high. Going

up from the Space Cabin, we can reach the top of the tower. If you'd like to spend a night in the Tower,

there are eleven hotels, KTV rooms and a disco hall.
