Divers in Budapest, Hungary has spent the last few weeks exploring the depth of what may be one of the biggest underground lakes in the world. The huge subterranean thermal lake was discovered in early 2008 and in a cave complex below a Turkish bath. A tunnel has been built to give greater access to the lake and the Hungarian government is reportedly considering opening the area to the public.
It is special because it is active, in the Budapest under the sea, a lot of caves. Seven big caves and three dozen smaller one(s). Together is 40 kilometers long. Sometimes it's very beautiful precipitations: gypsum, aragonite, calcite, baryte crystals. But all the other cave(s) are inactive and dry.
Budapest has built above the maze of the largely unexplored caves, filled with hot thermal water. The heat from that water helps heat the Turkish baths. The government plans to allow the researchers full access to the site prior to making any major decisions about public access and officials are planning to apply to have the cave system declared as a UNESCO World Heritage Site.

初二英语听力：Youth青春
Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and suppleknees; it is a matter of the will, a quality of the imagination, a vigor of the emotions;it is the freshness of the deep springs of life.
青春不是年华，而是心境;青春不是桃面、丹唇、柔膝，而是深沉的意志，恢宏的想象，炙热的恋情;青春是生命的深泉在涌流。
Youth means a temperamental predominance of courage over timidity of the appetite, for adventure over the love of ease. This often exists in a man of sixty more than a body of twenty. Nobody grows old merely by a number of years. We grow old by deserting our ideals.
青春气贯长虹，勇锐盖过怯弱，进取压倒苟安。如此锐气， 二十后生而有之，六旬男子则更多见。年岁有加，并非垂老，理想丢弃，方堕暮年。
Years may wrinkle the skin, but to give up enthusiasm wrinkles the soul.Worry, fear, self-distrust bows the heart and turns the spirit back to dust.
岁月悠悠，衰微只及肌肤;热忱抛却，颓废必致灵魂。忧烦，惶恐，丧失自信，定使心灵扭曲，意气如灰。
Whether sixty or sixteen, there is in every human being's heart the lure of wonder, the unfailingchild-like appetite of what's next, and the joy of the game of living. In the center of your heart and my heart there is a wireless station; so long as it receives messages of beauty, hope, cheer, courage and power from men and from the Infinite, so long are you young.
无论年届花甲，拟或二八芳龄，心中皆有生命之欢乐，奇迹
之诱惑，孩童般天真久盛不衰。人人心中皆有一台天线，只要你从天上人间接受美好、希望、欢乐、勇气和力量的信号，你就青春永驻，风华常存。
When the aerials are down, and your spirit is covered with snows of cynicism and the ice ofpessimism, then you are grown old, even at twenty, but as long as your aerials are up, to catch the waves of optimism, there is hope you may die young at eighty.
