The majority of people make an assumption that the human brain learns all by itself. But the truth is that to some extent, we can train ourselves to be better learners.

These kinds of learning behaviours are called "active learning". Here are a bunch of guidelines to become active learners.

Follow the outer voice

We all have two voices. Our inner voice expresses our personal opinions, while the outer voice handles others' opinions. Although our inner voice can be useful, it can also block us from learning. If we pay too much attention to it, we risk missing important information while learning. Instead, active learners are open-minded and focus on what the speaker/writer is saying, not on what their brain is saying.  

Debate with the inner voice

If we find it a struggle to control our inner voice, we can disagree with it as most active learners do. When our inner voice tells us a speaker/writer is wrong, think about why the speaker/writer may be right. If not, at least we have "listened to" another viewpoint.

Ask questions

One of the easiest ways to promote active learning is to ask questions. When we obtain information from someone, from books or the Internet, ask a series of questions about the topic.  In short, we should never stop being curious.

Seek the truth

Active learners make an attempt to question the world around them and get to the truth deep within each idea. Even when an idea sounds insane, there may be an aspect of it rooted in truth. No matter how crazy it seems, we will increase our chance of learning something.

Many people let learning opportunities slip because they ignore what is said because of who the speaker/writer is. But active learners don't judge people on the basis of first impressions. Instead, they separate the message from the messenger.

A. Concentrate your attention on the message itself.

B. Form opinions based on first impressions of messengers.

C. In this manner, they are in a better position to make decisions.

D. I suggest doing a number of things to actively take part in our learning.

E. Be flexible in our opinions and we might end up agreeing with the speaker/writer after all.

F. For example, we can stay active in the learning process and reflect on what we have learnt.

G. The answers will lead us to further learning and help us gain a deeper understanding of the topic.

If this year's turkey seems over salty, blame your brain.

The question of when saltiness becomes too salty is decided by a special set of neurons (神经元) in the front of the brain while a separate set of neurons in the back of the brain adjusts your appetite for salt, which the researchers showed in a series of experiments on mice.

"We are happy to drink sodas, sports drinks, and even tap water that contain a little salt. But if you imagine a very high concentration of sodium like ocean water, you really hate it. "says Yuki Oka, an author of the study and a professor of biology at Caltech. This hatred to super salty foods and drinks holds unless your body is really low on salt something that's pretty rare in people these days.

But experiments with mice found that when salt levels drop sharply, the tolerance for salty water goes up. The reason for this change involves at least two different interactions between the body and brain. When the sodium in the bloodstream begins to fall below healthy levels, a set of neurons in the back of the brain respond by dialing up an animal's desire for salt. Meanwhile. a different set of neurons in the front of the brain monitors the saltiness of any food or water the mice are consuming. And usually, these neurons will set an upper limit on saltiness. But when salt levels get extremely low, the body sends a signal that is superior to these salt-limiting neurons, which allows mice to tolerate the saltiness of sea water.

The new study also found evidence that the brain cells involved in salt tolerance respond to hormone-like substances called prostaglandins. These substances, which circulate in the bloodstream, are best known for their role in causing inflammation, fever, and pain. Now it's becoming increasingly clear that they also play a role in altering salt tolerance.

"Wars were fought over salt just a few centuries ago, and at least one previous effort failed badly, for a simple reason- awful taste. "says Stephen Liberles, a professor and Howard Hughes Medical Institute investigator at Harvard Medical School. So finding a better option may require more than just research on how the brain monitors salt intake. "Scientists also need to understand how that substitute will interact with our taste sense.

Classical Chinese furniture — a desk, a cabinet or any other fine piece of furniture and often out of precious wood —impresses us with its delicate shape. The secret of its graceful form is less visible and lies in its complicated sunmao(榫卯)system, which allows the various components to be assembled neatly without glue or nails.

Suzhou, a scenic and peaceful city in Jiangsu, a province long known for its wealth, developed its own tradition of classical furniture design over the centuries. Examples of the Suzhou-style furniture are currently on display as part of Oriental Wisdom in Sun Mao, a group exhibition at the Prince Kung's Palace Museum in Beijing.

Running until Sunday, the show demonstrates the way that the complex sunmao technique has been used in making furniture, as well as the variations that developed in different parts of the country. Also on display are models of different kinds, as well as the components of two chairs, which are disassembled and laid out to give museum goers a clear view of the inner structure of classical furniture.

The Suzhou style flowered during the Ming Dynasty(1368-1644), and once dominated the market in Jiangnan, the southern region along the lower reaches of the Yangtze River. It integrated input from the intellectual class, who put their ideals regarding living spaces and spiritual harbors into its design. According to Xu Jianping, one of the inheritors of classical furniture design in the city, the Suzhou style presents beauty in the same delicate way the city does, and represents the life philosophy of its people to achieve "refinement through careful calculations".

Guangzhou style furniture is normally made out of tropical hardwood, and its forms and decorative patterns show the influence of European furniture styles resulting from Guangzhou's history as an international trade port. The Beijing style, which is more splendid, incorporates aesthetic(美学)and stylistic elements from both Suzhou and Guangzhou.

"While the Suzhou style is light in weight and elegant in outline, furniture in the Beijing style is more magnificent, as it used to be made for royalty and aristocracy. "Xu says. "Ultimately, people live with their furniture, so the principle of quality furniture is that it should be appropriate to the space. "

With graduation time around the comer, it's a bitter-sweet moment for everyone involved.

Leaving school with style

It was inevitable that I would leave my school in London where I had spent most of my time. That day, we wore something a bit different from our usual suits and uniform and we all sat down and watched a high-light video of the last two years, including inspirational messages from our teachers and some funny photos. Two weeks later, we attended our school prom(毕业舞会), where we could dance and say a final goodbye to our teachers and friends.

Coming out strong

The graduation ceremony is one of the most memorable parts of school life in Kazakhstan. At the official farewell, teachers and parents expressed their wishes for our future and cracked some jokes about the graduates. Then students danced "the last waltz at school". One or two days later, the graduating students went to the after-party event, involving fresh air, camping and having cozy chats by campfire. There is a tendency not to spend money on after-parties. Instead, many choose to give it to charities.

Filled with traditions

There are many traditions in the graduation ceremony in the United States. On the graduation ceremony day, four hundred of us sat on the football field and listened to speeches before we got to "walk"—went up for our diplomas and shook hands with the principal. We were dressed in formal clothing, went out for dinners and then danced the night away. There was usually an after-party at some-one's house.

I was a single parent of four small children, working at a low-paid job. Money was always tight, but we had a roof over heads, food on the table, clothes on our backs, and if not a lot, always enough. Not knowing we were poor, my kids just thought I was serious. I had always been glad about it.

It was Christmas time, and although there wasn't money for a lot of gifts, we planned to celebrate with a family party. But the big excitement for the kids was the fun of Christmas shopping.

They planned weeks ahead of time, asking each other what they wanted for Christmas. Fortunately, I had saved $100 for presents to share by all five of us.

The big day arrived. I gave each kid a twenty-dollar bill and reminded them to look for gifts of about four dollars each. Then everyone scattered(散开). We had two hours to shop; then we would meet back at the gate.

On the way home, everyone was in high Christmas spirits, except my younger daughter Ginger who was unusually quiet. She had only one small, flat bag with a few candies. I was so angry, but I controlled myself and didn't say anything until we got home. I called her into my bedroom and closed the door, ready to be angry again. This was what she told me:

"I was looking around thinking of what to buy, and I stopped to read the little cards on the ‘Giving Trees'. One was for a little girl, four years old, and all she wanted for Christmas was a doll. So I took the card off the tree and bought the doll for her. We have so much but she doesn't have anything."

I gathered all the other kids and shared with them what Ginger had done.

……

According to my proposal, we all headed for the child welfare home nearby.

It is often challenging for teachers to make learning fun for students. If traditional methods of learning fail to capture students' attention, why not try a (create),approach?

One option is to provide students  opportunities to teach each other When children are given the  (responsible) for their own learning or the learning of others, they (encourage) to thoroughly understand the material  (make) opportunities for students to teach each other, teachers can assign each student  topic and ask them to prepare a lesson on that topic Once prepared, students can present the material (base) on their topic in front of the class.

Another approach is to have students work in pairs or small groups. Rather than immediately (seek) help from the teacher, students are required to rely on each other to solve any problems they encounter.

 (final), teachers can assign group projects to students,  will allow them to cooperate with their classmates, discuss problems together and make learning more enjoyable. When learning becomes engaging, students become more interested in it.

The Spring Festival is the most important festival for Chinese. This year, I decided to participate in all the activities organized for 1  students to celebrate the Spring Festival 

The preparation began a month ago, 2  our rooms with Spring Festival couplets(对联) and New Year paintings Later we 3  an activity to write Spring Festival couplets When I saw my teacher bring a special kind of pen, I became 4  to know what it was called In addition, we were going to use a brush to 5  Chinese characters on red paper Besides, there was another 6  thing called ink After 7  the tools needed for Spring Festival couplets, we started our 8  journey The teacher taught us how to hold a writing brush I tried to hold it, 9  it in the ink, and start writing carefully, but the 10  of the pen was too soft and I couldn't 11  it at all I was disappointed but I did not give up I carefully studied the teacher's 12  After several attempts , I wrote a line of words At this time, I found that my sleeves(袖子) were already filled with ink as I was too focused on13 .

Even so, I was very happy, because I felt that I had learned the 14 of writing calligraphy, that is, to hold the pen in the correct 15  Then I realized sometimes I have to experience something in order to understand it.

When you go on vacation next time, make sure to take lots of pictures of the wildlife you see. These photos can help save different types of wildlife because of a new field called" imageomics ". I mageomics uses computers to study pictures of wildlife and learn information from them.

Until recently, scientists didn't have the technology to analyze(分析) the data in wildlife photos. But now, machine learning and computer vision are helping researchers unlock valuable information hidden in these images.

There are platforms where people can share their wildlife photos, like eBird, iNaturalist and Wildbook. These platforms help scientists keep track of different species and create databases. If you have rare(稀有的) photos of wildlife, it's a good idea to share them on these platforms.

Scientists have limited time and resources to study all endangered wildlife in the world. By using artificial intelligence(人工智能) to analyze public photos, we can learn more about different species and their behaviors. This technology can even help us find things in photos that humans might miss.

It's important to use the collected information responsibly and protect it from poachers(偷猎者). If we do that, imageomics can not only help save wildlife but also contribute to other fields like medicine and agriculture.
