3 . There are hundreds of great national nature reserves in China. Now feast your eyes on the following amazing ones.
Qinghai Lake National Nature ReserveQinghai Lake, China’s largest saltwater lake in Qinghai Province, is a key body of water for lots of animals and birds. As an important stopover, migratory birds (候鸟) would rest in this area during their movement trip every year. The reserve became a national nature reserve in the year of 1997.
Bayanbulak National Nature ReserveThe only Bayanbulak Wetland, in Xinjiang Uygur Autonomous Region, is at the foot of Tianshan Mountains, which makes itself suitable for migratory birds. Bayanbulak means “rich spring water” in Mongolian, meaning that the area is rich in water. Every year, swans (天鹅) from different places fly here for nesting, which became a national swan reserve in 1986.
Rongcheng Swan National Nature ReserveAs one of the largest wintering places for swans in China, this reserve in Shandong Province mainly protects whooper swans (大天鹅), which make it different from other nature reserves. In 2007, it was changed into a national nature reserve. Now every year, thousands of whooper swans arrive here to spend the winter, making it an important resting and wintering place for themselves.
Sanya Coral Reef (珊瑚礁) National Marine Nature ReserveThis reserve focuses on protecting coral reefs and their living environment in Sanya City, Hainan Province. In 1990, it became a national nature reserve. This reserve is on the coast, so the area of the reserve has good water quality and many kinds of creatures,

4 . Family dynamics in the animal kingdom are as different as the animals themselves. In the animal world, there are advantages to be gained from being part of an extended family.
Chimpanzees
Chimpanzees are the world’s largest living primates. These creatures are peace-loving and may live together for a lifetime. The dominant male has many wives who may stay with him for most of their lives, which can cause everyday conflicts. It is the male who settles the conflicts by a warning stare or hitting the back of the offenders’ heads.
Elephants
Females stick together in the elephant world, living in herds under a stateswoman. The experience and knowledge of this elder one, who may be 60-years-old, are of great benefit. She will remember, for example,the location of water holes and seasonal food supplies. In times of danger, the group bunches around the young and it is the stateswoman who decides whether to flee or confront the threat.
Lions
Lions are the only cats to live in a large family group, guarded by a pair of powerful males. Family life is relatively harmonious and baby lions may be fed by any mother with milk, so orphaned babies do not starve. Males live in the wilderness for some years before seeking their own pride by challenging resident males in a bloody battle. The male lion protects his pride from other males and enemies.
Ostriches (鸵鸟)
Ostriches travel in bands of 10-50 individuals, the most remarkable birds being the eight-foot-tall males. The largest birds in the world, ostriches cannot fly, but run fast. The wives of the male ostrich all put their eggs in the same nest. A primary female will then join the male to hatch (孵化) the eggs and she will push away other eggs on the outside to ensure her own are in the middle.

5 . Last week, Chicago became the first city in the US to join the “Lights Out Plan”. People turned off the lights in the city’s tallest buildings, so that thousands of birds could get to their winter homes. Every year in autumn, some birds fly over Chicago on their way to the south, and come back the next spring.
Lights mean danger to birds. Birds find their way by looking at the stars in the sky. Lights in tall buildings are so bright that birds may mistake them as stars. This means they cannot find the right way to go home.
This month, about 300 types of birds are flying over Chicago to go back to the south to live through the cold winter. Birds fly to warmer places for a few reasons. Many birds cannot live in the cold, so they fly to warmer places. But there are other reasons, too. Birds need to look for food in the south. Another reason is that they want to have baby birds. Many birds like to have their baby birds in the same “house” they lived in last year, so they fly back there.
There are about 9,000 kinds of birds in the world, and about 600 kinds of birds migrate. Some birds can fly a very long way. Sometimes they fly to other countries. We have fewer birds today because there are fewer places for birds.

Milo is a rescue dog, adopted by 20-year-old Makayla Swift. But Milo the beagle is also a rescuer. One morning in November 2021, Swift opened her front door in Silver Spring, Maryland, and Milo took off running. Milo ran to the house across the street. He seemed unsatisfied with this house, so he ran to the one next door, Swift on his tail. He started scratching on the front door and Swift was thinking, “Why is he literally trying to break into her house?” She was embarrassed. Not everyone wants a strange dog on their property. But as she tried to drag Milo away, she could hear a sound coming through an open upstairs window. It was a voice yelling “Help!”
Hours earlier, around 4 a.m., 85-year-old Sherry Starr had risen from her bed. All of a sudden, standing there between the toilet and the tub, she slipped. She went down-hard-on the tile floor, and got stuck. Starr was scared of dying there. Her best bet, she decided, was to listen for the letter carrier in the afternoon and scream like the devils.

8 . If you’re a fan of nature shows, you’ve probably heard of the bombardier beetle (放屁虫). When disturbed, this weaponized insect can release boiling hot toxic chemicals from its end, a response that even the hungriest predators (捕食者) find highly off-putting.
But what if that predator is so quick that the beetle doesn’t have time to make its defense before it gets eaten? Turns out, the explosion is also effective when exploded from the inside. A new study shows that the beetles can use their chemical weapons to escape from the belly of the toad (蟾蜍) that ate them. They accomplish this Jonah-like feat by using their chemicals to encourage the toads to vomit (呕吐) them back up. The finding is served up in the journal Biology Letters.
Researchers collected 37 beetles and 37 toads from a forest in Central Japan. Some of the toads, those of the species Japonicas, share their habitat with the bombardier beetles. Others, the Torrenticola, inhabit the nearby streams and don’t normally encounter these beetles.
Back in the lab, the researchers paired off their collected specimens and each toad was allowed to swallow a single beetle. And then came the fireworks. As the authors note in their paper: “an explosion was audible inside each toad”, which means that somewhere in the belly, the beetles dropped their bombs.
What happened next depended on the participants. About 35 percent of the Japonicas toads, vomited the beetles. While 58 percent of the Torrenticola toads gave the researchers valuable feedback, literally— they vomited, too.
As for the beetles, the larger ones were more likely to make it back out. The lucky ones escaped in under 15 minutes. And those less fortunate were in there up to an hour and a half. And all 16 vomited beetles returned alive and were able to walk away. Fifteen of them were still kicking two weeks later. And one survived to tell his tale for another a year and a half.
