四、阅读理解。
Among all the natural wonders in the world, Lake Baikal in Russia always impresses me the most. It is not just a lake, but a miracle created by nature, full of unique beauty and secrets.
Lake Baikal is one of the oldest lakes on Earth, with a history of about 25 million years. It is also the deepest freshwater lake in the world, reaching a depth of 1,637 meters. The lake lies in the shape of a crescent moon, and its water is so clear that you can see small fish swimming freely under the surface. In summer, the lake looks like a huge blue mirror, reflecting the green mountains around it. In winter, the lake freezes, and the ice becomes as thick as 60 centimeters, creating a world of white and blue.
What makes Lake Baikal really special is its rich ecosystem. It is home to over 1,700 species of plants and animals, and two-thirds of them can’t be found anywhere else in the world. For example, the Baikal seal is a unique animal that only lives here. The lake also provides clean water for millions of people nearby and helps regulate the local climate.
People from all over the world come to visit Lake Baikal every year. They enjoy the beautiful scenery, take a boat trip on the lake, or walk along the shore. But more importantly, they come to feel the power of nature. Standing by the lake, you will realize how small humans are compared to nature.
Lake Baikal is a precious gift from nature. It is our duty to protect it. We should stop polluting the water and avoid damaging the ecosystem. Only in this way can we keep this natural wonder beautiful for future generations.
