Before Chu Wenwen stepped on the stage of this year's a Biodiversity Conference opening plenary (开幕式) on Oct. 11 and gave a speech, she     1    (practice) hundreds of times in front of a beaver (河狸) nest. Chu's beloved “audience” is a state-protected beaver,     2    is only found along Ulungur River in Xinjiang.

    3     the youth representative to the 15th meeting of the Conference, Chu shared her story of protecting endangered beavers and called on l million post-1990 s to join her efforts. “With our joint efforts, the number of beaver nests     4     (increase) from 162 to 190 over the past four years.” Chu said at the meeting.

Known as the “Beaver Princess”, Chu lives a life surrounded by wild animals. When she was 7, she got a camera from her father, an animal conservationist (保护者), and developed     5     deep love for these creatures. That's     6    she chose to return home after     7     (graduate) from Beijing Forestry University in 2017 and follow in her father's footsteps.

In 2018, Chu initiated the “beaver canteen “program. To raise money for it, she posted videos showing how beavers build dams and how she rescued wild animals. Now, Chu is working on a new program called the Beavers' Ark, a hospital for     8    (injure) wild animals. Earlier this year, she took care of a poisoned vulture (秃鹰) carefully until it was     9     (full) recovered.

“We think what we have done is     10    (meaning). We will continue to encourage more people, especially the youth, to participate in nature conversation,” Chu said.

Mirror, Mirror, on the Wall:

Can Animals Recognize Their Reflection at All?

Daniel Povinelli was in high school when he first read about an experiment published in 1970. It left a deep impression     1     him as it showed that chimpanzees, rather than monkeys, can recognize themselves in mirrors. All it took was a simple mirror    2     (reveal) that our close chimpanzee relatives are self-aware.

This famous mirror self-recognition experiment was conducted in the 1960s by scientist Gordon Gallup, Jr. No such tests had been done before     3     people had long observed animals interacting with mirrors. In this experiment, the chimps originally tried to attack the image in the mirror. But after a couple of days, they began using the mirror to examine parts of their bodies such as their teeth. He then anesthetized(使麻醉) them and put red dye on their face. The chimps later woke up and reacted to the unexpected mirror image as if they     4     understand that the marks were on their own faces. In Gallup’s view, passing this test proved that the chimps had self-awareness, which was an evolutionary leap     5     (make) only by humans and their close relatives and led to empathy and higher-level thinking.

Though convinced at first, Povinelli now holds a different view on what animals may be doing after spending years     6     (commit) himself to studying mirrors and higher-order consciousness for years. He holds that animals may have a     7     (complicated) sense of their own body’s movement than we imagine. With that kind of physical self-concept, a chimp could use a mirror as a tool to examine its body. But that wouldn’t indicate anything about the richness of the animal’s inner life. Recent research also shows monkeys can actually learn to perform this skill, if they     8     (give) the proper training.

Povinelli says people     9     live with cats and dogs tend to project their own understanding of the world onto their pets. Since they can’t directly ask     10     their pets are experiencing, their projection is very likely to be wrong.
