Wang Yuheng is on a mission to protect the Antarctic. In February, after     1    (join) Greenpeace on the Antarctic ship tour, where he came face-to-face with wildlife in the region, he returned to China with the message     2     the area must be protected.

Wang is one of thousands of people in China, including Olympic athletes and movie stars, who have promised support     3     the creation of an Antarctic protection zone. “Two things I experienced in the Antarctic Ocean left a deep     4    (impress) on me,” Wang said. “The first was how seasick I     5    (feel) as giant waves crashed into our ship heavily. But as I lay on my back, I thought about how the penguins can swim at 36 kilometer per hour in those icy waters, and I couldn’t help but     6    (strike) by what a powerful animal the penguin is.”

In China, Wang became famous on the reality show “The Brain” when he amazed audiences with his ability     7    (recognize) one in hundreds of seemingly identical objects. Now, Wang is focusing his brainpower on a task with     8    (globe) importance—die creation of the largest protected area on Earth.

“The Antarctic is     9     only region in the world that has never been home to human civilization. It’s like the white space in an ink painting. We have a responsibility not to cause any     10    (far) damage,” Wang said.

Several mass extinction events have occurred in the course of our planet’s history. Scientists say that previously the     1     (reason) for extinction have varied, but human actions will be to blame for the sixth extinction which has already started to happen. It is clear that human activity negatively affects almost every natural thing on Earth from destroying different species of plants and animals     2     creating various types of greenhouse gases. In fact, species are being wiped out at a     3     (fast) rate now than any time in history.
