Computer programmer David Jones earns $35.000 a year designing new computer games, yet he cannot find a bank ready to let him have a credit card. Instead he has been told to wait another two years until he is 18. The 16-year-old works for a small firm in Liverpool where the problem of most young people of his age is finding a job. David's firm releases two new games for the fast growing computer market each month.

    But David's biggest headache is what to do with his money. Even though he earns a lot he cannot drive a car, take out a mortgage（抵押贷款）, or get credit cards. David got his job with the Liverpool-based company four months ago, a year after leaving school with six O-levels and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs”, he said. David spends some of his money on records and clothes and gives his mother 50 pounds a week. But most of his spare time is spent working.

    “Unfortunately, computing was not part of our studies at school”, he said “But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway.” David added, “I would like to earn a million and I suppose early retirement is a possibility. You never know when the market might disappear.”

    The world's population is more mobile (移动的)today than ever before. In 2010, more than 200 million people left their home countries to live in a new country. This is about 3 percent of the total world population. Some experts believe that number will swell to 400 million by 2050. Rates of immigration have remained strong for the last 300 years, but patterns of immigration have changed since World War II. The backgrounds and experiences of today's immigrants are different from those of the typical European immigrant of the nineteenth and early twentieth centuries. Contemporary immigrants range from unskilled laborers to highly skilled professionals, and they come from and go to countries all over the world.

    In the nineteenth century and until World War II, immigration was primarily in one direction- from the Old World to the New World. This is no longer the case. Countries such as Russia and China, which have long been, and continue to be, significant source countries, are now also destination countries. There is also considerable mobility inside regions, such as from one European country to another, or among the countries of the former Soviet Union.

    In spite of such differences, the push and pull factors for immigration remain essentially the same as they were 100 years ago. Most people move to another country because they want a better life. For the majority of immigrants, this means better economic conditions. As in past generations, a labor shortage in one country often draws workers from another country, especially if wages are significantly higher. In some small countries, for example, Qatar, United Arab Emirates, and Kuwait, there are more jobs than citizens. The demand for labor is so high that the majority of the population consists of foreign-born workers, ranging from highly skilled engineers and financial experts to domestic and construction workers.

    In traditional destination countries, such as the United States, however, labor needs have changed. Today, although there is still demand for unskilled labor, there is increasing demand for people with a high level of skill and education. The need for less skilled labor has shifted to other countries. As work on farms and in industry in the United States and Canada once drew workers from all over the world, now work in factories in Taiwan and south Korea attracts workers from Vietnam, the Philippines, and Cambodia.

    Most global immigration is legal: however, a large number of people also move across national borders illegally in pursuit of(寻找) employment. Experts estimate that about 15 to 20 percent of immigrants worldwide are in their new countries illegally. The United States has the largest number of these immigrants, followed by South Africa, with significant numbers also in Northern and Western Europe and Mexico. These immigrants face particular challenges because they often must hide from the authorities who might deport them back to their home countries. Their illegal status also means that employers may take advantage of them by forcing them to work longer hours and paying them less than the legal minimum wage.

    Although economics remains the most important motivation in all forms of immigrant, other factors are also important. Some people decide to leave their home countries because their actions or political beliefs make it dangerous for them to remain. Others choose to leave because their home country has become too dangerous and unstable, often because of war or political unrest. They wish to find a place that is secure for themselves and their families. Education is also a significant factor for many modern immigrants. They want to raise their children in a place where they can get a good education, which, in turn, they hope will provide them with better prospects for the future. Finally, family and community ties also play a role in immigration decisions. As in the past, once a group of people from one country establishes a community in a new country, more people from that country is likely to follow.

    The pattern, direction, and rate of immigration may change as the global economy changes. However, as long as life in a new country is more attractive than life in the old country, immigration will continue.

    When Veronika Scott was a student at the College for Creative Studies in Detroit, Michigan, she received a task to “design to fill a need.” She dreamed up an idea for overcoats that would double as sleeping bags, made 25 of them, and handed them out to people living in shelters on an abandoned city playground. While her efforts were greeted mostly with enthusiasm from those braving Detroit's cold winters, one woman voiced dissatisfaction. “We don't need coats; we need jobs,” she told Veronika. Then she had her second inspiration.

    After graduating from college in 2012, Veronika founded the Empowerment Plan, a nonprofit organization. She hired two homeless women to sew the coats and paid them with donations she received through her blog. Now, the Empowerment Plan employs about 20 people and has produced more than 10,000 coats and distributed them in 30 states, Canada, and elsewhere abroad.

    “We don't require previous employment,” Veronika says. “We're looking for people who are motivated.” The Empowerment Plan provides free classes and lends money to those who qualify. Nearly all the employees eventually move into permanent housing, and some go on to jobs in the auto industry and construction.

    Veronika has bettered the coat's design by making its outer layer of a lightweight material that resists air, wind, and water and its inner layer of a material that stores body heat. Still, Veronika is less focused on the coats than on the workers who make them. “At the end of the day,” she says, “the coat is a vehicle for us to employ people.”   

    Inside Out is one of my favorite Disney / Pixar movies. The story is about a young girl named Riley who moves from Minnesota to San Francisco with her family and how she deals with her emotions (情感) through the move. These five emotions in Riley's brain are Joy, Fear, Anger, Disgust (厌恶) and Sadness. These emotions play a very important role in her life. I can understand because I am an 11-year-old girl and I am very in touch with my emotions and pre-teen feelings.

    The film is extremely beautiful and you couldn't ask for better direction from Pete Doctor. The use of the right colors for the characters is great. For example, Joy is yellow, Sadness is blue, Disgust is green, Fear is purple and Anger of course is red. Sadness plays a main role in the story and it makes me wonder why we are told not to be sad. I think it's important to be sad when the time comes. The end of the movie pretty much got me and the whole audience (观众) (families, couples and even elderly people) in tears and I cried very hard.

    I recommend (推荐) this movie for anyone from 8 to 18 because it has enough joy in it for younger kids to like it even though it does have some sad moments. I believe that adults will like it too. And I give it 4 out of 5 stars because it connects to an older audience even though it is designed for a younger audience. I think younger children can see this, but a parent would have to explain some things to them after the movie.

Humans aren't the only animals that move to music. Parrots have been known to do it. And now rats have been observed bopping their heads in time with the tunes of Mozart, Lady Gaga, Michael Jackson and others, according to a new paper from the University of Tokyo. What's more, the rats seems to respond to the same beats that get humans' feet tapping (轻跺). 

The researchers played a sonata by Mozart for lab rats at different variations of the original speed. Wireless sensors on the rats' bodies tracked their movements. Meanwhile, 20 human participants were involved and listened to the same music through headphones equipped with motion sensors. 

It was observed that the rats' head movements were the most obvious when the music played at its normal speed, which was around 132bpm (beats per minute). The same was true for human participants. The researchers then changed to some pop songs such as Lady Gaga's "Born This Way" and Michael Jackson's "Beat It". As with Mozart's, rats moved their heads along the rhythm of pop songs, similar to how people do, at about 120 to 140bpm. 

The study showed that both rats and humans moved their heads along to the beat in a similar rhythm. The level of head bopping from both humans and rats decreased as the music sped up. The study suggests that there is something similar about the way human and rat brains respond to rhythms, but rats do not match their motions to the beat like humans do. Humans can predict the timing of a beat and move predictably to it. 

Aniruddh Patel, a psychologist who studies brain response to music, says humans and parrots respond to beats with big, voluntary movements such as head shaking, dancing or foot tapping. Patel also stresses that this study does not show that rats have the same emotional associations with music as humans do. Yet he believes it could help reveal how humans and some other animals developed a sense of rhythm.
