Read the passage of the Dead Sea and choose the right answers. ( 2 * 5 = 1 0 points ) 阅读有关死海的文章,选择正确答案。 The Dead Sea is not a sea. It is a big lake in the Jordan Valley( 约旦河谷 ). It is near the city of Jericho( 耶利哥 ). The river Jordan runs into the Dead Sea. It comes from the north. The lake is 400 meters below sea-level. The sun is hot there. The water is salty. Fish cannot live in the salty water and plants cannot grow near it. People cannot swim well in the Dead Sea. But they can float on the water. In the picture, a woman is floating on the lake. She is reading a piece of newspaper. The water is very blue and the air is clear. In winter people come to the lake. They sit in the sunshine or bath in the warm water.
