六、阅读与回答问题
Eight years ago, a one-week-old milu named Diandian was found near a lake, which looked too weak to survive. But now, she is the mother of three baby milu, thanks to the care at the East Dongting Lake National Nature Reserve.
On March 18 this year, Diandian gave birth to her youngest baby, named Sansan, meaning "three-three", as it is her third baby and was born in the third month of the year. Li, the president of a milu conservation association in Yueyang, took good care of Diandian and her baby. "As our country is paying more attention to environmental and wildlife protection, more people are aware that milu are state-protected animals," Li said.
Milu habitats, which are usually centred around water, are now free of fishing tools that once threatened (威胁) them. On May 27, a team of experts watched milu near Dongting Lake. It takes time and luck to meet and count them, especially when they live in the thick reeds (芦苇) that are 4 to 5 metres tall. The team leader, Song, first saw a milu when he was a student in 2009. Since then, he has helped protect the habitats at Dongting Lake. As the flood season is coming, Song and his team will go around the lake area day and night to save milu in trouble and provide feeding when needed.
With the improving environment around Dongting Lake, China's second-largest freshwater lake, the wetland has become the cover for wildlife again. "We will continue to protect these rare animals and their habitats," Song said.
