They have a deep knowledge of human in the past. They usually like to study maps and to read stories about people’s lives.

A person must be educated and develop skills to be a history teacher. A history teacher must have a college degree.     2    . Teachers must be able to communicate well. They must know how to present information to their students and how to manage a classroom. They also need to enjoy working with young people.

Students who want to be history teachers can begin to gain the skills they need while they are still in high school. They can take social studies courses. They can help classmates with schoolwork. They can work. ,with young children. These activities help students prepare for their college studies.

    3    . These courses help beginning teachers learn how to work with students. In their last year of college, students in teaching programs act as student teachers. As student teachers, they may work in junior high or high school classrooms. Skilled history teachers watch them and help them.

    4    . These documents show that a person has been educated for a job. States usually require teachers to pass one or more exams before they receive their licenses.

A new teacher can find a job in many ways. Schools often post job advertisements at colleges or on the Internet.

What we do there largely determines our standard of living and our status to a considerable extent. It is sometimes said that because leisure has become more important, the injustices of work can be pushed into a comer, and that because most work is pretty intolerable, the people who do it should compensate for its boredom, frustrations and humiliations by concentrating their hopes on the other parts of their lives. For the foreseeable future, however, the material and psychological rewards which work can provide will continue to play a vital part in determining the satisfaction that life can offer.

Yet only a small minority can control the pace at which they work or the conditions where their work is done; only for a small minority does work offer scope for creativity, imagination or initiative.

Inequality at work is still one of the most glaring（明显的）forms of inequality in our society. We cannot hope to solve the more obvious problems of industrial life, many of which arise from the frustrations created by inequality at work, unless we handle it determinedly.

The most glaring inequality is that between managers and the rest. For most managers, work is an opportunity and a challenge. Their jobs engage their interest and allow them to develop their abilities. They are constantly learning. They are able to exercise responsibility. They have a considerable degree of control over their own and others' working lives. Most important of all, they have opportunities to initiate. By contrast, for most manual workers, work is a boring, dull, even painful experience. They spend all their working lives in intolerable conditions. The majority have little control over their work. It provides them with no opportunity for personal development. Many jobs are so routine that workers feel themselves to be mere cogs （齿轮）in the bureaucratic machine. As a direct consequence of their work experience, many workers feel alienated （疏远）from their work and their firm.

【推荐2】Laughter Yoga(瑜伽) is one form of yoga. Madan Kataria, a doctor in Mumbai, India invented it. He believed that people had forgotten how to really laugh. Through his research he made an interesting discovery. The human mind does not know the difference between forced laughter and real laughter. Forced laughter can also lead to a feeling of happiness.

And then Kataria had the idea for a group of people who would laugh together. He gathered a few of his friends together. They met in a public park in Mumbai. That small group grew and grew! And this is how people began to do Laughter Yoga. People doing Laughter Yoga usually meet together in a Laughter Club. Kataria’s friends formed the first Laughter Club in 1995.

Today, there’re over 5,000 Laughter Clubs in 53 countries. But what exactly do people do in a Laughter Club? People in Laughter Yoga meetings usually do a series of exercises. The exercises include body movement, correct breathing, and of course, laughter! At the beginning of the meeting, people may have to force themselves to laugh. But by the end, everyone is usually laughing in a real way! Each meeting is a little different. But there are common exercises groups may do.

Experts say that the exercises help blood move around the body faster. They also say that Laughter Yoga helps people deal with the bad things in their lives. They say that a person may go into a Laughter Club meeting feeling sad, angry, or worried. But then, people act happy. After a time, forced laughter becomes real laughter. This is one reason why people may enjoy laughter Yoga so much.

【推荐3】Charles Darwin found inspiration for his theory of evolution in birds’ beaks, giant tortoise shells — and language. “The survival of certain favored words in the struggle for existence is natural selection,” he wrote in The Descent of Man in 1871．

Language gradually shifts over time. Much research examines how social and environmental factors influence language change, but ignores the forces of human cognitive selection that fix certain words into the lexicon (词汇表). For an extensive new study published recently, scientists investigated just that.

In an experiment like a game of telephone, thousands of participants read English-language stories and rewrote them to be read by other participants, who then rewrote them for others. Only certain words from the first stories survived in the final versions. Researchers analyzed the word types speakers consistently favored, theorizing that such preferences drive language change over time. The scientists also separately analyzed two large collections of English historical texts from the past two centuries, containing more than 40 billion words — again seeing only certain types survive.

The end result shows three properties that give words an “evolutionary advantage” by helping them stick in the brain: First, words typically acquired at an early age (such as “hand,” “uncle”or “today”) are stabler. Next, concrete words linger (逗留) better than abstract ones: “dog” persists longer than “animal,” which persists longer than “organism.” Lastly, emotionally exciting words — whether negative or positive — tend to endure.

Early language-evolution models assumed that language becomes increasingly complex over time. But Fritz Breithaupt, a cognitive scientist, says the new study supports a more recent theory that language ultimately gets more efficient and easier to understand. Still, as the study notes, “the English language is not baby talk.” Breithaupt explains: “Yes, we shift toward simple language, but then we also grab complex language that we need.” New words that address the complexities of modern life may somewhat balance out this shift.

Columbia University linguist McWhorter more or less agrees with the study’s results about evolutionary advantages within language. He questions, however, implications regarding the overall efficiency of English — a language which contains things like “needlessly complex” grammatical traces.
