A group of highly endangered Yangtze finless porpoises (江豚) was recently seen in the Yangtze River in the area of Wuhan, Hubei province, 【小题1】may be a result of China’s 10-year ban on fishing in the river at the beginning of the year 2020, less interference (干扰) from human 【小题2】(activity) or an increase in food availability.

Recorded in a short video by a local resident, the rare appearance 【小题3】(attract) attention online on the right day.

The finless porpoise 【小题4】the Baiji dolphin (Yangtze River dolphin), both members of the cetacea family and the only two aquatic mammals (水栖哺乳动物) in the river, were officially considered as “critically endangered” and placed on the red list of the 【小题5】(threaten) species by the International Union for Conservation of Nature in 2013.

Among the very few porpoise species, the Yangtze finless porpoise is the only one 【小题6】(live) in freshwater, according to Zhang Xianfeng, an aquatic wildlife researcher at the Institute of Hydrobiology of the Chinese Academy of Sciences. 【小题7】(it) small size and cute “smile” make it a much-loved animal in China and beyond.

“Rising water levels during the flood season together with the fishing ban 【小题8】(probable) contribute to this rare animal’s appearance, given that sandbanks 【小题9】(cover) by water and more water plants are available for fish. Without 【小题10】(interrupt) from human beings, the finless porpoise might be more active,” Zhang said.

Known as the ＂Guardian of Dogs＂ in Zhengzhou, Henan Province, Zhou Yusong has spent the last 8 years rescuing homeless dogs and 【小题1】 (offer)them a home.

It all started in 2008 【小题2】 Zhou Yusong noticed an injured homeless dog by the side of a road. It had been hit by a car and was struggling 【小题3】 his life, but everyone just ignored it. Unable 【小题4】(do) the same, he took it to a nearby pet hospital. After saving the animal’s life, he took it to a dog shelter, as he had no way of taking care of it 【小题5】(him), in his small apartment. 【小题6】(shock) by the large number of homeless dogs already at the shelter, he became more involved in trying to make their lives easier.

Zhou Yusong convinced one of his 【小题7】(friend) to invest 800,000 yuan in a new animal rescue center. He 【小题8】(agree), and let Zhou in charge of running it. The animal lover was happy to do it, and 【小题9】 (actual) quit his job so he could devote all his time to caring for the dogs.

According to xwtoutiao, Zhou Yusong 【小题10】(rescue) over 700 homeless dogs in the last 8 years.

“The adults and babies in the heard are all in good health,” said Chen Fei, 【小题2】 (direct) of the National Forestry and Grassland Administration’s Asian Elephant Research Center.
