 阅读理解The Jiangxi government have taken some measures to protect finless porpoises (江豚) which are also called the "smiling angel". This kind of animals are facing serious changes in their living environment because Poyang Lake—China's largest freshwater lake has entered the dry season 100 days earlier.A Yangtze finless porpoise was first seen in Poyang Lake, Jiangxi Province in 2018. The number of this animal has decreased to 1,012 in 2017, with 457 living in Poyang Lake. However, as the water level fell to less than 12 meters in August, the lake entered this year's dry season the earliest since records began in 1951.Last weekend, a traveler to the shoreline of Poyang Lake, posted a video showing the dead body of a finless porpoise on a dry riverbed. The other six finless porpoises have been found dead during the past five years. Zhou Wei, a science writer, said: "The reduction of water makes the finless porpoises swim to the deep water of the lake." This situation has increased the propoises' risk of hitting by boats working on the lake." Extremely dry weather will also affect the reproduction (繁殖) of fish in the following year, which may result in a food shortage. He told that the propoises give birth in spring and autumn, so now it is an important period to feed newborns.Wang Liang, who was from the Agriculture and Rural Affairs of Jiangxi said that the province had released a total of 200 million fish and crabs into the water to enrich the food supply. Meanwhile, "More than 2,000 volunteers have been invited to protect and rescue the species," he added. （1） What happened to the Poyang Lake in Jiangxi? A . The dry season of the lake came earlier.
