The basic mathematical principles are clear.

Basic mathematics introduces the basic concepts of students' mathematics and the basic principles of difficult fields. These 30 wonderful courses are designed to help students understand how to prepare for arithmetic and algebra (algebra and transcendence).

The basic mathematics in this course covers every basic arithmetic aspect. They also study exponent, operation order and square root. In addition to learning how to perform various mathematical operations, students find out why these operations work, how specific mathematical problems involve other branches of mathematics, and how to use these operations almost.

It is relatively easy to transfer from basic mathematical concepts to more troublesome ones, which makes students' understanding of materials stable and clear. The opportunity to give students "meaningful" mathematics knowledge may be so terrible. They also help students prepare for college mathematics and overcome their worries about this amazing-completely understandable-field research.

At the end of the course, students can improve their understanding of basic mathematics. They will be able to get rid of these mysterious mathematics and study themselves more confidently than they thought. In addition, they will enhance their ability to accept new and exciting math problems.

Professor H. Siegel, praised as "the best math teacher in America" by Kentucky Education Television, is a loyal teacher and has great talent in explaining math concepts in a way that makes them look clear. From basic concrete ideas to more abstract questions, he is a master-learner of mathematics lectures, not so terrible.

Doctor of Mathematics Education. Dr Siegel of the University of Georgia teaches mathematics at Central Arizona University. His courses include all kinds of cosmetics and a lot of lessons for future primary school teachers.

If the course is not completely satisfactory to you, you can easily switch to other courses we offer. Or you can take the money back.

Peanuts are here.

After reading my article proudly, I looked around the room and found my classmates laughing and crying with them. I looked at the teacher's face in doubt. There is no choice, I will slowly report what I spent in the past, hoping to hide myself. "What makes everyone like this?"

Soon, I flashed back to the day when Miss Lancelot gave me the task. This is the first real conversation I have received from my new school. It seems simple: looking for information online and a man named George Washington. Because my idea comes from an ancient history teacher in my hometown, I have never heard of this name before. When I searched this guy's name, it was obvious that two people with the same name looked completely different! One invented hundreds of uses of peanuts, while other types of troops led the whole United States. I stared at the screen, not knowing which one my teacher was referring to. I called my grandfather for advice; Flip a coin The front is the commander, and the back is the peanut man. Ah! Tail, my report will be written by george washington carver, the great inventor of peanut butter.

A few weeks later, standing on this unfriendly quality, I was completely lost. Oh, I put the paper away, sat at the table and burned it to see what I had done wrong. When a classmate started his report, all this became clear. "My story is George Washington, who started the American Revolution." The whole world has become very! How do I know what she means, George Washington?

Obviously, my grades are terrible. Sad and fearless, I decided to turn things around. Miss Lancelot and I, but she insisted: there is no beginning; There is no new grade. I think such punishment is unreasonable, and I think I deserve a second chance. Therefore, in the rest of the school year, I devoted myself wholeheartedly to my work with enthusiasm. 10 months later, this opportunity showed that I found myself sitting in the principal's office, which was completely different from my grandfather's conversation now. I smiled and flashed back to the embarrassing moment. At the beginning of this year, I informed the headmaster that I chose to skip the sixth grade. Justice is sweet.

Decision making under pressure

A new analysis based on research shows that the way of acute stress will affect the strengths and weaknesses of our brain thinking, causing it to focus on happiness and ignore a decision that may have negative consequences.

Studies have shown that stress may change people's choices in a predictable way.

"Stress will affect the way people learn," Professor Marathi said. "People learn more from positive stress than negative results."

For example, two recent studies have observed how people learn to connect images (images), or reward and punish images. In an experiment, some participants first emphasized giving speeches and doing math problems in front of a group of audiences; Others emphasize putting their hands in ice water. In both cases, it is emphasized that compared with people who have never experienced stress, the subjects remember that the reward materials are more accurate and the punishment materials are not accurate enough.

This phenomenon may not be surprising to anyone who tries to resist eating cookies or smoking, although under pressure-at those moments, only happiness-related activities will appear in my mind. However, the research results further show that stress will have a dual impact. Not only are rewards easier to remember, but negative consequences are also easy to remember.

The study also found that the influence of stress on decision-making is different for men and women. Although both men and women tend to pay attention to the reward of results and less stress, their responses to risks are different in frequency.

When men emphasize the cold water task, they tend to take greater risks, while female subjects react in the opposite way during the experiment. In a tense situation, risky behavior may give you a lot. Men may do better, heavier and more cautious. However, women will win.

The decision to slow down this trend and become more cautious is risky, which may also help explain why women are less addicted than men: they may avoid risky choices more often and eventually become addicted.

wasteland

"In the wilderness (wilderness) is a preserved world." This is a famous saying that a writer thinks that one of the founders of environmental protection theory. Frequency is a borrowed mirror. There is a heated debate about environmental protection: whether to keep the core of the local wilderness.

As John Sullivan of England pointed out, in the wilderness of images, there is a powerful voice, untouched and beyond anything else. They say that the nature of many people is the most valuable price. The impulse to leave these video themes is not very strong, and the dangerous mining (development) brings such scenery (landscape) is real. Some of these wasteland also play the role of rain forest, for example, storing a lot of carbon. According to Mr. Suowen, these "ecosystem services" far outweigh the benefits of being protected from development.

Lee Lane, a visiting scholar at the Hudson Institute, holds the opposite view. He admitted that this wasteland provided useful services, such as water conservation. But he believes that this is not a reason to avoid all human existence, and in fact it is not a reason for commercial and industrial development. There are more people on the ground, and they reasonably and legally hope to live a better life, not just struggle for survival. Although the method of using resources has been improved, the demand for raw materials is still increasing, some of which are abundant in the wilderness. If they can use these wilderness areas without reducing services, the debate continues and there is no reason not to do so. Being touched is not a feature that deserves more attention than anything else.

I saw these ideas being further forwarded and influenced by other participants. One of the challenges is to show yourself. For me, in both cases, the question of spiritual value is a little more direct. There is a practical question whether the wilderness can be used harmlessly.

This is a theme that not only calls for free expression of emotions, but also guides rationality. In the process of protecting the world, where to enjoy the wilderness is obviously worthy of more serious consideration.

make over

Last year, researchers at the University of Michigan reported that in the past 10 years, college students' ability to sympathize with and understand others declined sharply. __7 1__ Nowadays, people spend more time alone and are less likely to join groups and clubs.

Jennifer released a joint project for teenagers, another explanation. Turn on the TV, you are bathed in news and reality shows, full of people's struggle, competition and general disrespect. __72__

There are good reasons not to follow those bad examples. Human beings are closely related to society. The researchers also found that understanding teenagers are more likely to have high self-esteem. Besides, compassion can cure loneliness, sadness, anxiety and fear.

Empathy is also a sign of a good leader. In fact, many top companies report that compassion is one of the most important things and they are looking for new managers. __74__ "Scholars are important. But if you don't have emotional intelligence, you won't succeed in your work or love life, "she said. "

What's the best way? What's your EQ? First, let your guard down and listen to others. __75__

To really develop singing skills, you'd better volunteer to go to a nursing home or hospital, join a community or team, have a diversified membership, enjoy a circle with your family, or spend time taking care of pets in an animal shelter.

A. Everyone is different, and the level of empathy varies from person to person.

Researchers say this may be because many people have replaced meeting time and watching TV.

C. "A person without empathy will have many opinions and endless conversations," Fried said.

D- What are the most examples of human learning process, but they are considerate.

The problem of empathy is to learn how to understand others-both, how they think and feel.

F. Good social skills-including empathy-are a kind of "emotional intelligence", which will help you live successfully in many fields.

G. an important part of building relationships with others is being treated by real people-compassion is decisive, and those relationships. ]

We also have to translate the college entrance examination papers. This is a lie. Probably not accurate. Please forgive me.
