More than three decades ago, Chu Hongjun, a young man from East China’s Shandong province, traveled to Northwest China’s Xinjiang Uygur autonomous region, 【小题1】 (throw) himself into wildlife research and protection work in Altay prefecture. Today, his 27-year-old daughter, Chu Wenwen, sticks to the faith of her father. More than that, she has 【小题2】 (successful) called on more than 1 million young people in making a joint effort to create a better living environment for the Mengxin beaver (海狸), the only beaver species living in China, 【小题3】 is only found along the Ulungur River in Altay.

The web-savvy (精通网络的) youngster has initiated a project to livestream, 24 hours a day, how the beavers live in the wild. Infrared (红外线) cameras 【小题4】 (fix) so that viewers can monitor the ecological circulation around those small habitats 【小题5】 (build) by the beavers. “We are the young generation that grew 【小题6】 amid the internet boom. Today, modern online communication tools and advanced 【小题7】 (equip) used for scientific research enable us to gather more people together in the pursuit of wildlife protection,” she says.

Additionally, Chu Wenwen is also willing to take parents and their children on field trips 【小题8】 (observe) beavers firsthand. She believes that if opportunities are provided for people to learn more about the animal, they’re 【小题9】 (likely) to take actions to protect it.

“We can bridge 【小题10】 gap between the public and the beavers,” she says.

Greenland sled dogs, a curly-tailed species native; to the fierce Arctic environment, could be the 【小题1】 (old) dog species , according to the first study that 【小题2】 (hold) to take a deep dive into the animals' genetic history. The sled dog branch of the family tree, 【小题3】 includes various types of huskies (爱斯基摩犬) , broke off from the rest 【小题4】 the dogs around 9,500 years ago, versus something like a labradoodle, which only 【小题5】 ( become) a breed in 1989.

Scientists know that dogs likely evolved from Eurasian wolves, but 【小题6】 (exact) when or where that transformation took place is a matter of great mystery. 【小题7】 (understand) the genetics of sled dogs better and their place in the world , scientists studied the gene of a dog from Siberia, dating to around 9,500 years ago.

“I was actually expecting that we would find some sort of pioneer of domestic dogs ,” says lead author Mikkel - Holger Sinding, a Ph. D. student at the University of Copenhagen in Denmark. Instead, he and 【小题8】 (he) colleagues found today's sled dogs and the Siberia dogs were from the same branch. “It means that all dogs must have diversified (多样化) earlier than this,” he says. That's a huge 【小题9】 (find), Sinding says, because it provides the first firm date for diversification in dogs” - in itself 【小题10】 important clue in the mystery of dog domestication (驯化)。

Freedom and Jeff

Freedom and I have been together 10 years this summer. She came in as a baby in 2011 with two 【小题1】 (break) wings, thin and dirty. We made the decision to give her a chance at life, so I took her to the vet's office. From then on, I was always around her. We had her in a huge dog carrier with the top off, and it was loaded up with shredded newspaper for her to lay in. I used to sit and talk to her, urging her to live, to fight and she would lay there looking at me with those big brown eyes. We also had to tube feed her for weeks. This went on for 4-6 weeks, and by then she still couldn't stand. It got to the point 【小题2】 the decision was made to euthanize (安乐死) her if she couldn't stand in a week.

She was going to be put down that Friday, and I was supposed to come in on that Thursday afternoon. I didn't want to go to the center that Thursday, 【小题3】 I couldn't bear the thought of her being euthanized, but I went anyway and when I walked in everyone was grinning from ear to ear. I went immediately back to her cage; and there she was, standing on her own, a big beautiful eagle. She was ready to live. I was just about in tears by then. That was a very good day. We knew she could never fly, so the director asked me to glove train her.

In the spring of 2013, I was diagnosed 【小题4】 non-Hodgkin’s lymphoma (淋巴瘤). I had stage 3, which is not good, so I wound up doing eight months of chemo (化疗). Lost the hair- the whole bit. I missed a lot of work. 【小题5】 I felt good enough, I would go to Sarvey and take Freedom out for walks. Freedom would also come to me in my dreams and help me fight the cancer. This happened time and time again.

Fast forward to November 2013, I went in for my last checkup. I was told that if the cancer was not all gone after eight rounds of chemo, then my last option was 【小题6】 stem cell transplant. I went in Monday, and 1 was told that all the cancer was gone. Amazing!

So the first thing I did was 【小题7】 (get) up to Sarvey and take the big girl out for a walk. It was misty and cold. I went to her flight, and we went out front to the top of the hill. I hadn’t said a word to Freedom, but somehow she knew. She looked at me and wrapped both her wings around me to where I could feel them 【小题8】 (press) in on my back, and she touched my nose with her mouth and 【小题9】 (stare) into my eyes, and we just stood there like that for I didn't know how long. That was a magic moment. We 【小题10】 (be) soulmates since she came in. This is a very special bird.
