Idema, a Dutch Sinologist（汉学家）, has served as the director of the Chinese Languages and Cultures Department at Leiden University of the Netherlands and was also director of Harvard's Fairbank Center for East Asian Research.He has studied ancient Chinese plays, novels and literature, and has authored or translated a number of influential books published in English and other languages.

    The 70-year-old Dutch Sinologist recalled his half-century-long romance with Chinese culture during a recent visit to Beijing.As a child,the vivid descriptions of China in Nobel and Pulitzer Prize-winner Pearl S.Buck's books sparked Idema's interest in the country.He later read classic Chinese literature and spent whole days pouring through works at the National Library of China.

    While many other experts on China focused on the country's economic transformation, Idema continued to study traditional Chinese literature."There were scholars studying law, religion and society, but not traditional Chinese literature,which was my personal interest," Idema explains.

    Finding reference books for his research,especially regional publications,used to be a huge challenge,and Idema used to spend a lot of time collecting books and other materials during visits to China.Now it is much more convenient with the Internet.

    Idema usually chooses less-known subjects for his research and tries to get firsthand materials.In recent years, he has devoted himself to translating Chinese folk tales and writing about Chinese folk society and folk culture.

    "Traditional Chinese culture is a passion.I have been studying it for 50 years and will continue to do so,"says the retired professor.

The Basics of Math—Made Clear

    Basic Math introduces students to the basic concepts of mathematics, as well as the fundamentals of more tricky areas. These 30 fantastic lectures are designed to provide students with an understanding of arithmetic and to prepare them for Algebra(代数) and beyond.

    The lessons in Basic Math cover every basic aspect of arithmetic. They also look into exponents(指数), the order of operations, and square roots. In addition to learning how to perform various mathematical operations, students discover why these operations work, how a particular mathematical topic relates to other branches of mathematics, and how these operations can be used practically.

    Basic Math starts from the relatively easier concepts and gradually moves on to the more troublesome ones, so as to allow for steady and sure understanding of the material by students. The lectures offer students the chance to “make sense” of mathematical knowledge that may have seemed so frightening. They also help students prepare for college mathematics and overcome their anxiety about this amazing—and completely understandable—field of study.

    By the conclusion of the course, students will have improved their understanding of basic math. They will be able to clear away the mystery(神秘性) of mathematics and face their studies with more confidence than they ever imagined. In addition, they will strengthen their ability to accept new and exciting mathematical challenges.

    Professor H. Siegel, honored by Kentucky Educational Television as “the best math teacher in America,” is a devoted teacher and has a gift for explaining mathematical concepts in ways that make them seem clear and obvious. From the basic concrete ideas to the more abstract problems, he is master in making math lectures learner-friendlier and less scary.

    With a PhD in Mathematics Education from Georgia State University, Dr. Siegel teaches mathematics at Central Arizona College. His courses include various make-up classes and a number of lectures for future primary school teachers.

    If the course fails to provide complete satisfaction to you, you can easily exchange it for any other course that we offer. Or you can get your money back.

In the latest beauty craze(狂热)sweeping social media in China，women--and even some men--are boasting that they are paper thin，by posting photographs of their waists behind a vertical(垂直)piece of A4 paper．To qualify，the waist must be entirely hidden by the paper．A piece of A4 paper is 8.3 by ll.7 inches，roughly the size of a sheet of American letter paper．

    With the A4 Waist，the trend is attracting hundreds of photographs and thousands of comments on Weibo and other social media networks like Weixin or WeChat．Being abnormally thin is a widespread standard of beauty for women，one that has been criticized as an unhealthy ideal of female attractiveness．

    The tiny waist has a long tradition in China，going back at least to King Ling of Chu，who ruled from 540 to 529 B．C．Many in China know the passage from the Book of Han，the history of the Western Han Dynasty：“The King of Chu loved a narrow waist．Many people at court starved to death．

    Several commentators have found the A4 trend disturbing．In a telephone interview，He Xiaobin，senior fashion features editor at the Chinese edition of GQ magazine，said，“I find it completely stupid．Everybody has a different frame and body shape．Using a single size to define all human beings and thinking you have created a new standard is foolish．''The A4 waist challenge annoyed him，saying that it allows certain people to gain bragging rights，while leaving others in depression．

    Luckily，some who do not qualify are turning to humor for comfort．Can they substitute a different paper size，such as A3，which is 11.7 inches across Or measure a body part besides the waist?

    Welcome to your future life!

    You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150, so at 40, you're not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of look the same age!

    You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change clothes' color or pattern.

    You walk into the kitchen. You pick up the milk, but a voice says,“ You shouldn't drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.

    It's time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.

    So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli ,”it has to be so much better that it replaces what we have already.” The Internet is one example—what will be the next?

    Some of the best research on daily experience is rooted in rates of positive and negative interactions, which has proved that being blindly positive or negative can cause others to be frustrated or annoyed or to simply tune out.

    Over the last two decades, scientists have made remarkable predictions simply by watching people interact with one another and then scoring the conversations based on the rate of positive and negative interactions. Researchers have used the findings to predict everything from the likelihood that a couple will divorce to the chances of a work team with high customer satisfaction and productivity levels.

    More recent research helps explain why these brief exchanges matter so much. When you experience negative emotions as a result of criticism or rejection, for example, your body produces higher levels of the stress hormone, which shuts down much of your thinking and activates (激活) conflict and defense mechanisms (机制). You assume that situations are worse than they actually are.

    When you experience a positive interaction, it activates a very different response. Positive exchanges increase your body's production of oxytocin, a feel-good that increases your ability to communicate with, cooperate with and trust others. But the effects of a positive occurrence are less dramatic and lasting than they are for a negative one.

    We need at least three to five positive interactions to outweigh every one negative exchange. Bad moments simply outweigh good ones. Whether you're having a conversation, keep this simple short cut in mind: At least 80 percent of your conversations should be focused on what's going right.

    Workplaces, for example, often see this. During performance reviews, managers routinely spend 80 percent of their time on weaknesses and “areas for improvement”. They spend roughly 20 percent of the time on strengths and positive aspects. Any time you have discussions with a person or group, spend the vast majority of the time talking about what is working, and use the remaining time to address weaknesses.

    Recently．I've been following a simple rule that is helping me crush procrastination(拖延症)and making it easier for me to stick to good habits at the same time{#blank#}1{#/blank#} There are two parts to the 2-Minute Rule…

    Part 1—If it takes less than two minutes，then do it now．

{#blank#}2{#/blank#} For example，washing your dishes immediately after your meal，tossing the laundry in the washing machine，taking out the garbage，sending that email，and so on．

    If a task takes less than two minutes to complete，then follow the rule and do it right now．

    Part 2—When you start a new habit，it should take less than two minutes to do．

    Can all of your goals be accomplished in less than two minutes? Obviously not．But，every goal can be started in 2 minutes or less{#blank#}3{#/blank#}

    It might sound like this strategy is too basic for grand life goals，but I beg to differ．The 2-Minute Rule works for big goals as well as small goals because of the inertia(惯性)of life{#blank#}4{#/blank#} I love the 2-Minute Rule because it embraces the idea that all sorts of good things happen once you get started．

    The most important part of any new habit is getting started—not just the first time，but each time．It's not about performance，it's about consistently taking action．

    I can't guarantee whether or not the 2-Minute Rule will work for you{#blank#}5{#/blank#} Anyone can spare the next 120 seconds．Use this time to get one thing done．Go．

A．I call this little strategy the“2-Minute Rule”．

B．And that's the purpose behind this little rule．

C．Here's what you need to know to stop procrastinating．

D．Once you start doing something，it's easier to continue doing it．

E．But，I can guarantee that it will never work if you never try it．

F．The goal is to make it easier for you to get started on the things you should be doing．

G．It's surprising how many things we put off that we could get done in two minutes or less．
