①Choosing seating in the classroom can have an influence on a students performance (表现), a study suggests.

②Researchers from Sheffield Hallam University in the UK did a survey on students' seating positions in a classroom. Here are the results.

③The more prepared and hard-working students sit in front rows. They almost always score higher on exams. Perhaps, the front row is the perfect position for students who have trouble concentrating (集中注意力). Also, sitting closer to the front of the classroom does have an influence on the student-teacher relationship, which is connected with greater performance.. According to a study in2018, the Grade Point Average (平均成绩) decreased (下降) by 0.1 point for every row further back students sit.

④Still, some students prefer the middle rows. Dr. Robert Wallace, a member of the National Education Association, thinks of choosing to sit in the middle of the classroom as one of the worst decisions a student can make. "In a classroom, a teacher's eyes often go to the front and the back of the classroom. They don't look at the centre of the classroom very often or with the same amount of attention" said Dr. Robert Wallace.

⑤If neither the front nor the middle is suitable for a student, there can only be one way out: the back. The back row would have the lowest value. That's where students are more likely (有可能的) to chat, play video games or do some other things. However, things are not always what they seem. There are also some good students who work hard in the back row.

China, with Four Great Inventions, in ancient times, has once again showed its ability to change the world with its “new four great inventions”: high-speed railways, electronic payments, shared bicycles and online shopping.

The four innovative ways of life are most popular among young people, according to a survey by the Belt and Road-Research Institute(一带一路研究院) of Beijing Foreign Studies University.

“The ‘new four great inventions’ are all related to China’s high-tech (高科技), which made the lives of people easier in China,” said Wu Hao, the director of Beijing Foreign Studies University.

“My wallet is no longer in use. I can buy and eat whatever I want simply with my phone,” said Lin Jinlong, a foreign student from Cambodia, adding that “Even pancake sellers are using Alipay (mobile payment). We can also order food at home, which is super convenient. If I were at home in Cambodia, I would have to go outdoors.”

As a big fan of bicycles, he also showed his love for China’s shared bicycles, saying that “shared bikes are bringing cycling (骑单车) back to people’s lives---and they are making public transport(公共交通) more convenient and less crowded, and encouraging people to be more active.”

Rebacca Fannin, the founder of Silicon Dragon(硅谷之龙), noted that China is beginning to lead in innovation in some ways.

“It is increasingly clear that China is inventing and no longer copying western ideas. It is also increasingly clear that China is leading in many ways such as social messaging app WeChat,” she said.

That year, I was a Junior 2 student. Falling off the stairs hurt me in the head. Almost everyone thought I was dead. But they were wrong. However, it was difficult to get back to normal life. I had to leave school and learn everything, walking, talking, and yes, maths.

To help me with that task, Mrs. Pillar volunteered to come to the hospital and later to my house once a week. We began with basic maths skills. As time passed by, I made progress.

I remember very vividly how she came to my home on Sundays, sat with me at the kitchen table and threw different coins on the table. She asked me to show her 38 cents, 17 cents, 63 cents. It was challenging, but she also made it fun.

After a year and a half, I had progressed a lot, both in body and mind, to return to school. Seven years later, I graduated from the University of Texas at the top of my class.

As years went by, I always kept in touch with Mrs. Pillar. Unluckily, one day my parents told me that Mrs. Pillar had been in hospital because she suffered a stroke (中风).

Now it was my turn to help her. Mrs. Pillar lay in bed, unable to speak or know anybody around. I pulled some coins out of my pocket, dropped them on her bed, and asked her to show me 12 cents. The nurse thought that my action was very strange until one day Mrs. Pillar smiled happily as I began working with—just as she had worked with me years before. She made progress every day and was moved out of ICU (重症监护室) and finally out of hospital.

One day, I called to wish her a happy New Year. She spoke into the phone excitedly, “Happy New Year to you and your family, Michael. Thank you for everything you’ve done for me.”

Mrs. Pillar was one of my Junior 2 teachers, but she taught me so much more about life than only maths.

It Is Never Too Early to Think—and Communicate—like a Scientist

Who is a scientist and what is his job? A chemist doing experiments? A geologist out studying rocks? When most people think about science, they imagine characters making discoveries or finding cures (治疗方法)for new diseases. However, these leave out an extremely important part of the scientific process: communicating—sharing the results of that work.

Imagine if someone discovered something important about a disease. Other scientists need to understand the work well enough to use these new developments to make even more discoveries in the future. The public, too, needs to understand how these discoveries might influence their lives. But none of this will be possible if the work is not shared. Being a scientist goes far beyond the moment of discovery.

Without clear communication, scientists would not be able to use the work that has already been done. So how do scientists tell others about the work that they have done? How do they make sure that everything that they share is as clear and correct as possible?

Researchers publish their work in scientific journals(期刊).These journals can be read by other researchers around the world. It is very important for these journals, and for the scientists who read them, to make sure that the research included is as correct as possible. In order to do that, articles given to scientific journals before publication first go through a process called peer review. Other scientists who do research in areas related to the work in an article are asked to read through it. Scientists also provide feedback to the writers. They bring up new questions the writer may not have considered, recognize limitations to the results being described, and also make sure that no mistakes were made during the process.

Frontiers for Young Minds is a scientific journal written for—and reviewed by young people. All of the articles in it are based on works already published in a peer reviewed scientific journal. However, while scientists are good at making sure that articles are understandable for other scientists, there are no better experts to make sure that something can be understood by young people than the young people themselves. By working together with an experts young reviewers read the article to see if any part of the article is hard to understands make it clear why the experiment was done in the way it was done and check whether the figures (数据)clearly explain the point of the article.

Basically, these young reviewers learn to think like scientists. It is never too early to start! Ask questions, learn new things, and don't forget the importance of communicating your findings.
