Recently, the Nandagang wetland in Hebei Province has become home to over 300 oriental white storks (东方白鹳), a species under first-class national protection. This number is three times that of the same period last year.
These birds, widely found in China, Japan and Korea in former times, are so rare and special that they are listed as endangered by the International Union for Conservation of Nature (世界自然保护联盟). Therefore, they have strict requirements for their living environment. Only wetlands with clean pools, and little pieces of land with large quantities of food and water can become their habitats.
This large, long-necked bird ranges in height from 60 cm to over 150 cm (2 to 5 feet). The feathers on the body are mainly pure white. The wings are wide and long. All or part of the head and upper neck may be featherless and brightly coloured.
Oriental white storks began to leave their breeding (繁殖) places from late September to early October, forming groups and travelling southward. Along the way, it’s necessary to choose suitable places to rest, and some places can rest for more than 40 days. They often gather in open areas like grasslands, lakes for activities. Most storks are found in groups except during the breeding season. They feed during the day. Most eat small animals caught in areas of water or fields that are not deep, such as small fish, frogs, insects and so on.

【推荐1】Making Friends with Ducks
In traditional pet stores, you can buy an animal to be your companion at home. But there’s a new kind of “pet store” where you can spend some time with animals and just walk away without taking any of them with you. What really matters is to be there.
My colleagues and I visited one of these stores in the Sanlitun neighborhood of Beijing. We were looking for Call ducks (柯尔鸭), a Dutch species of pet ducks. They are famous for their cute looks and their sky-high prices—one of them can easily cost a few thousand yuan. Since we were not planning to spend so much on a duck any time soon, visiting them in one of these places—what I'd call “mini-zoos”—seemed to be the perfect choice.
There were five Gall ducks at the store and we spent a good three hours with them. We learned a lot about the species.
Call ducks are not as obedient enough to follow what they are told to do as dogs, so playing with them takes a lot of chasing from our side and quacking (呱呱叫) from theirs. Also, don’t expect them to be house-trained—one of the ducks actually pooped (排便) while sitting on my lap. But none of this took the pleasure out of holding them in my hands and touching their full chests.
That’s the magic of animals—you are refreshed again.

【推荐2】A holiday on a mountain bike can be really exciting. As you ride along, problems are forgotten, and you can get healthy at the same time! It’s a great way to see the country and you can stop whenever to walk along the way. You’d be surprised how far you can travel in two weeks. When you go by bike you can take routes (线路) a car couldn’t, so you’ll find that your journey goes up and down hills, through forests and across valleys…much more interesting than a motorway! Like most sports, mountain biking isn’t dangerous but you should have the right equipment (装备). It’s important to wear a helmet and suitable clothing, and to choose a route that’s up to your health conditions. It’s also quite cheap, because once you’ve bought the bike (you can find good bargains in second-hand markets and on the Internet), very little extra money is needed, except for regular maintenance of the bike. Anyway, it’s always worth it!
Some technical (技术的) knowledge is useful, however, if you are thinking of doing a long journey. You should be prepared to make minor repairs. For example, you might have to change a tyre, or repair the brakes and there will be other small problems during a trip. Most of this knowledge can be found in a good bike repair book. Of course, if you don’t have these skills, it doesn’t mean you can’t go on any long trips. Perhaps you could go with someone who is good at mending things!
One other important piece of equipment is a First Aid kit. It’s more possible for you to get small cuts and bruises than major injuries, but even the best bike-riders fall off sometimes. It’s all part of the experience!

Now, primary students learn cooking at school. It has been discussed by teachers and parents. Some think that it is a useful skill for students, while others think it’s a waste of time. Some even think it’s just a show. But do they really understand cooking?
It’s been said that good cooking is an art form (形式). The truth is that it’s much more than that. When talking about different foods from all around the world, or cultures and histories of dishes, students are connected to the world and learning history and culture in a new field. When learning cooking, students measure (称量) materials from time to time, or find oil and water don’t usually mix. Students are also learning maths and science in practice.
The importance of failures (失败) in making food is as much as successes. Li Mei, 11, was crazy about the yummy cakes made by her father and wanted to make one on her own. But when taking her cake out, she was frustrated (沮丧的) to find that the cake was hard and black at the bottom. Her father told her when he was 13, he tried to make cakes, but wasted boxes of eggs. Then together with father, Li Mei found out what had gone wrong and succeeded in making one. Li Mei learned in the failure of cooking, and could be braver to face failures.
Besides the practical skills, cooking builds character (性格). It encourages kids to work with others. It also encourages them to be open to foods they might not have tried. Though being good to our health, carrots were hated by 12-year-old Xiao Lei. But he started to love them after he made a salad with them. By cooking, students put down their phones and work together with family members in the kitchen. By cooking, students form the habit of doing labor (劳动) work. As a part of labor education, cooking is a way to teach kids important 21st century skills, such as creativity and teamwork. If these skills aren’t taught to today’s students, they might hardly survive (生存) in the future.

【推荐1】Have you ever seen pandas that aren’t black-and-white? Scientists have found that there are brown-and-white pandas living in a mountain in China.
Scientists studied the genes (基因) of different pandas in the wild and they have found that pandas with brown-and-white coats are the result of changes in the natural environment. To understand what lies behind the special color, the scientists studied Qizai, a brown panda in Hanzhong. He is now the only brown panda in captivity (圈养).
When compared with hair from three black-and-white pandas, Qizai’s brownish coat had fewer and smaller melanosomes (黑素体). What’s more, the melanosomes were more likely to be differently shaped, the study team found. The scientists then collected genetic information about Qizai and pieced together his family tree.
The scientists studied the genetic information from Qizai’s family members and compared it with the genetic information from 12 black-and-white pandas from the Qinling Mountains and 17 black-and-white pandas from other places in China.
While none of Qizai’s family members had brown coats, the scientists were able to show that his parents and son all had one copy of the recessive trait (隐性特质) on a certain gene, while Qizai had two copies. The scientists then studied another 192 black-and-white pandas. The gene change causing the brown coats was only found in two pandas from the Qinling Mountains in Shaanxi, not Sichuan province, where most China’s pandas live.
It’s not clear what caused the genetic change. Scientists said it must be because of the environment of the Qinling Mountains, which is different from that of Sichuan. “For those who care about pandas, this is a great development,” said Wang, who worked in the mountains for 10 years. Wang said he was glad to see the scientists’ efforts in trying to work out this scientific question.

【推荐3】A record of 1,101 manatees (海牛) died in Florida last year, many from hunger. So last December, government wildlife experts thought up a plan to give food to the manatees. They decided to feed them green vegetables like lettuce and cabbage. Ron Mezich, an expert, said, “We’re making a difference.” So far, they have served up more than, 193,000 pounds of lettuce to hungry manatees. But as the weather is getting warm, the program is expected to end soon.
Manatees are huge sea animals that only eat sea grass and other plants that live in the sea. That’s one reason why they’re sometimes called “sea cows”. Since 1967, Florida’s manatees have been on the US government’s list of endangered animals. Most dangers to manatees come from humans. One of the biggest problems facing the animals are boats. Manatees are curious and fairly slow. That has led to thousands of manatees being hit or killed by boats. At one point, there were only about 2,000 manatees left in Florida. With protection, the number increased. In 2016, there were more than 6,000 manatees.
However, as sea grass began to disappear, the number of manatees keeps going down again. Warming seas with polluted water have created huge growths of algae (藻) on the ocean’s surface. The algae blocks the sunlight that allows the sea grass to grow. For example, in Indian River Lagoon, where manatees often go in the winter, about 90% of the sea grass beds there have died off. Long term, Florida will work to help restore (恢复) sea grass beds. But that will take time. Scientists still worry that hundreds more manatees could starve this winter.
