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.

    The entire house was lit with lights. It was Meera's wedding the next day. Seema walked to her daughter's bedroom. Meera was not there, so she left the envelope on Meera's bed and went away. When Meera came back after a bath downstairs, her eyes fell on the envelope. She picked it up and opened it Sitting on the bed, she started to read it：

    My darling daughter, I'm so happy for my darling is getting marked! To such a good man! At the same time, I'm a little worried, too. The reason? You're going to a new house where everything is going to be new: the people, relationships and surroundings. Yes, you're smart and Vinod will be there with you to help, but I have a few things to say:

    Accept Vinous parents as your parents. Remember that your mother-in-law will have her own understanding about you. So it's up to you give her a good impression.

    Earn respect from family members. If that means changing yourself a little bit and adapting to their customs, just do it. It will help you to settle into your new home.

    Never compare your mothers home and their home. It may not be appreciated.

    The kitchen is one place where small fights can appear. Ifs your mother-in-law s kingdom, so ask her permission if you want to cook something. If she offers help, accept it. This Ml help in building trust between you. Similarly, offer her your help when she s busy cooking. Thus, a new relationship -will be born: one of respect and understanding.

    Finally, respect your husband, as he's your life partner. Remember that a marriage re-quires trust, love and compromise (妥协).

    I could have sat with you and told you, but I felt that writing all this down would make you understand better and I'm sure you'll give your whole heart to this relationship. Remember that both Papa and I are here for you always.

Love,

Ma

    You probably know who Marie Curie was, but you may not have heard of Rachel Carson. Of the outstanding ladies listed below, who do you think was the most important woman of the past 100 years?

    Jane Addams (1860-1935)

    Anyone who has ever been helped by a social worker has Jane Addams to thank. Addams helped the poor and worked for peace. She encouraged a sense of community by creating shelters and promoting education and services for people in need. In 1931, Addams became the first American woman to win the Nobel Peace Prize.

    Rachel Carson (1907-1964)

    If it weren't for Rachel Carson, the environmental movement might not exist today. Her popular 1962 book Silent Spring raised awareness of the dangers of pollution and the harmful effects of chemicals on humans and on the world's lakes and oceans.

    Sandra Day O'Connor (1930-present)

    When Sandra Day O'Connor finished third in her class at Stanford Law School, in 1952, she could not find work at a law firm because she was a woman. She became an Arizona state senator (参议员) and, in 1981, the first woman to join the U.S. Supreme Court. O'Connor gave the deciding vote in many important cases during her 24 years on the top court.

    Rosa Parks (1913-2005)

    On December 1,1955, in Montgomery, Alabama, Rosa Parks would not give up her seat on a bus to a white passenger. Her simple act landed Parks in prison. But it also set off the Montgomery bus boycott. It lasted for more than a year, and kicked off the civil-rights movement. “The only tired I was, was tired of giving in,” said Parks.

    The dangers of drowsy (昏昏欲睡) driving have been widely known. Now several companies have developed face-tracking technology that can tell when drivers become dangerously sleepy.

    Here is how it might work: A camera in your car monitors your facial expression, compares it to a database of expressions and determines if you are likely sleepy or distracted. The car then alerts you to pay attention or pull over.

    Affectiva has developed emotion recognition technology that aims to detect when people are just starting to get tired. The idea is to catch the warning signs before drowsiness really strikes. "Actually, when someone is drowsy, that is too late." Gabi, vice president of Affectiva said. "What if you can see trends in someone's face about five minutes before they become sleepy?" Affectiva's program can recognize seven different emotions and 15 facial expressions. Its standards were developed by sifting (筛选) through a database of 4 million faces from 75 counties, said Zijderveld. She suggested that carmakers could coordinate (协调) the program's facial recognition data with oral reminders, such as sound warnings, or (nonverbal) alerts, like a change of temperature and vibrations (continuous slight shaking movements).

    Eyeris is another company working in facial analytics. Modar Alaoui, the company's CEO, said that its software detects "eye openness" in addition to other facial indicators. The software can also read head position, which may indicate when someone begins to nod off.

    These technologies aren't the first attempt to fight drowsiness behind the wheel. Inventors came up with the similar device "sleeper beeper" to prevent sleep in cars back in 1983. The sleeper beeper was attached to a driver's ear and would issue a noisy warning when the driver's head nodded past a certain point. But the latest software would intervene (干涉) earlier and more effectively.

The next time you attend a social function or go to a place where people meet and interact, take note of the number of people who have adopted the same gestures and posture—the way you sit or stand--of the person with whom they are talking. This "carbon copying" is a means by which one person tells the other that he is in agreement with his ideas and attitudes. By this method, one is non-verbally (非语言的) saying to the other, "As you can see, I think the same as you, so I will copy your posture and gesture."

    This unconscious (无意识地) mimicry is quite interesting to observe. Take, for example, the two men standing at the hotel bar. They have mirrored each other's gestures and it is reasonable to assume that they are discussing a topic upon which they have the same thoughts and feelings. If one man uncrosses his arms and legs or stands on the other foot, the other will follow. If one puts his hand in his pocket the other will copy and this mimicry will continue for as long as the two men are in agreement.

    This copying also occurs among good friends or people of the same social position and it is common to see married couples walk, stand, sit and move in very similar ways. People who are strangers, however, try hard to avoid holding mutual(相互的) positions. The significance of carbon copying can be one of the most important non-verbal lessons we can learn, for this is one way that others tell us that they agree with us or like us. It is also a way for us to tell others that we like them, by simply copying their gestures.

    If an employer wishes to develop immediate friendliness and create a relaxing atmosphere with an employee, he needs to copy the employee's posture to achieve the end. Similarly, an up-and-coming employee may be seen copying his boss's gestures in an attempt to show agreement. Using the knowledge, it is possible to influence a face-to-face encounter by copying the positive gestures and postures of the other person. This has the effect of putting the other person in a receptive and relaxed frame of mind and he can "see" that you understand his point of view.
