More than three decades ago, Chu Hungnam young man from East China’s Shandon g 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 started a project to livestream (直播), 24 hours a day, how the beavers live in the wild. Infrared (红外线) cameras 【小题4】 (use) recently 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】 during 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 will be 【小题9】 (likely) to take action s to protect it.

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

On the northern tip of New Zealand's South Island, there is a long bar of sand【小题1】(call)Farewell Spit. The area is famous, but for a【小题2】(desire)reason. It's a hotspot of whale stranding(搁浅).Whales strand【小题3】(they)on beaches. Are these coastlines the whales’ graveyards?

In February, 2015, 200 pilot whales became stuck on the shore. It was the biggest stranding in the area in over a decade, according to local conversation team.【小题4】(rescue)spent hours trying to refloat them, but 100 died. Without the support of water, the weight of their bodies【小题5】(break)their muscles.

The【小题6】(remain)whales were watered and kept as comfortable as possible by volunteers equipped with buckets and spades. Sixty were eventually refloated, but soon stranded again. Members of the Public helped to refloat them【小题7】second time and now the whales【小题8】(believe)to be back at sea.

Beaches like Farewell Spit are perhaps the most places【小题9】whales can die. To all purposes, it seems as if the whales have killed themselves by swimming too close【小题10】the shore. So are beaches places in which whales go to die—or are there other graveyards that we don't know about? It's a mystery that has been around since ancient times.

Every autumn, millions of the North American monarch butterflies 【小题1】 (begin) a long and difficult journey. Somehow they manage to travel around 4,000 kilometres south and find their way to California or Mexico. However, until recently no one knew how they did this.

A team of scientists 【小题2】 (lead) by Professor Eli Shlizerman has now found the answer. They have found out that the monarch is able to tell the time of day. 【小题3】 uses its eyes to measure the position of the sun. These two pieces of information allow the butterfly 【小题4】 (determine) the way to go. Finally, it manages to reach the places where it will spend the winter.

【小题5】 (sad), human activity is the main reason 【小题6】 the number of monarch butterflies is falling. In many of the places where the butterfly can be found, people are destroying the 【小题7】 (nature) environment. They cut down trees and use chemicals that kill the plants that monarch caterpillars eat.

The research on the monarch’s behaviour has however led to a greater 【小题8】 (aware) of this creature. People have been working together to record its migration and make sure that there are enough plants for it to feed 【小题9】 . If this works, there may come a time when 【小题10】 number of monarch butterflies increases once again.
