Since the beginning of human evolution, men have migrated（迁移）across continents in search of food, shelter, safety, and comfortable weather. People still move for these reasons, but new reasons for human migration are arising, such as job relocation(重新安置) and overpopulation.

    Three million migrants are moving from poor countries to wealthier ones each year, and increasingly, their destination is a neighboring country in developing parts of the world. People are moving within the developing world for the same reasons as they migrate to wealthier nations. People from poor countries are going to less poor countries, fleeing wars and conflicts. They are also responding to population pressures because some countries are densely populated, and they often have high population growth. Those people need to go somewhere else.

    There are three main reasons why people move. The basic categories and percentages are as follows, according to the Current Population Surveys (CPS):

    Family-related reasons account for 26.3%, including changes in marital（婚姻的） status, establishing a household and other family reasons; work-related reasons 16.2%, including job transfer, retirement, and other job-related reasons; housing-related reasons 51.6%, including new and better houses, better neighborhood, cheaper housing and other housing reasons; the remaining 5.9% of other reasons are attending college, the change of climate and health reasons.

    Americans have been migrating south and west for decades in search of better job opportunities and warmer climates. They have also been moving to places a little far from cities, in search of bigger yards and houses, lower crime rates and better schools. In 1950, nearly a fifth of the population lived in the nation's 20 largest cities. In 2006, it was about one in ten. That's why many American people say, “Big Cities Shrink as People Move South, West.”

    Between March 2005 and March 2007, 73.4 million Americans moved. Fifty-six percent of these moves were within the same country. Twenty percent were between counties but in the same state. Nineteen percent were moves to a different state. Some families even went abroad.

Quiet Virtue: The Conscientious

    The everyday signs of conscientiousness (认真尽责)—being punctual, careful in doing work, self-disciplined, and scrupulous (一丝不苟的) in attending to responsibilities—are typical characteristics of the model organizational citizen, the people who keep things running as they should. They follow the rules, help out, and are concerned about the people they work with. It's the conscientious worker who helps newcomers or updates people who return after an absence, who gets to work on time and never abuses sick leaves, who always gets things done on deadline.

    Conscientiousness is a key to success in any field. In studies of job performance, outstanding effectiveness for almost all jobs, from semi-skilled labor to sales and management, depends on conscientiousness. It is particularly important for outstanding performance in jobs at the lower levels of an organization: the secretary whose message taking is perfect, the delivery truck driver who is always on time.

    Among sales representatives for a large American car manufacturer, those who were most conscientious had the largest volume of sales. Conscientiousness also offers a buffer (缓冲) against the threat of job loss in today's constantly changing market, because employees with this quality are among the most valued. For the sales representatives, their level of conscientiousness mattered almost as much as their sales in determining who stayed on.

    There is an air around highly conscientious people that makes them seem even better than they actually are. Their reputation for dependability influences managers' evaluations of their work, giving them higher evaluations than objective measures of their performance would predict.

    But conscientiousness in the absence of social skills can lead to problems. Since conscientious people demand so much of themselves, they can hold other people to their own standards, and so be overly judgmental when others don't show the same high levels of model behavior. Factory workers in Great Britain and the United States who were extremely conscientious, for example, tended to criticize co-workers even about failures that seemed unimportant to those they criticized, which damaged their relationships.

    When conscientiousness takes the form of living up to expectations, it can discourage creativity. In creative professions like art or advertising, openness to wild ideas and spontaneity (自发性) are scarce and in demand. Success in such occupations calls for a balance, however; without enough conscientiousness to follow through, people become mere dreamers, with nothing to show for their imaginativeness.

    A class teacher, in my opinion, plays an important role in a child's development.{#blank#}1{#/blank#} This year, she is moving to Class Three and I can't wait to see how things are going on.

    Last year, my daughter did not like her teacher at all. It was so bad that she did not look forward to school. It was a year full of trouble and that worries.

   This year, Miss Purity is gentle and humorous. It's hard not to like her.{#blank#}2{#/blank#}.

    She becomes an early bird. Last year, mornings were like a fight because I had to force Tasha to hurry up when she was preparing for school. I had to pull her out of bed, tell her to take breakfast and then drove her to school. But now, our mornings are like a party. She wakes up early, prepares everything at a high speed and then rushes to school to be with Miss Purity.

    She's happy. She enjoys school and school work and keeps talking about what they did at school when she comes home.

    She's responsible.{#blank#}3{#/blank#} But now she never forgets even her water bottle at school. She makes her bed and helps in the kitchen.

    Her diary is full of praises. The diary is the tool of communication between the teacher and the parents. Last year, her diary was always full of negative reports. One time, she poured water in a child's lunchbox, another time she threw another kid's textbook in the toilet.{#blank#}4{#/blank#} She's always volunteering to clean the blackboard, the teacher's chair and desk.

    {#blank#}5{#/blank#} Finishing her classwork was such a big problem. She had to do it at home. But now, she finished both the classwork and homework at school.

A. Here are the changes in my daughter.

B. Now she began to share her snacks with those who did not have anything.

C. Every year when my daughter moves to a new class, I have a usual big worry—her new class teacher.

D. Her diary was good.

E. She has a good class teacher.

F. She used to be careless and forgetful.

G. She does well in school.

    Questions to Ask Before Getting Your Child a Cellphone

    At what age should you get your child a cellphone？{#blank#}1{#/blank#}However，before you decide to add your child to your family plan，ask yourself these questions.

    {#blank#}2{#/blank#}

    If you and your child are not often apart beyond school hours，a cellphone may not be a serious necessity，but if he is independent or involved in extracurricular (课外的) activities outside your home，a cellphone could be useful，especially during emergencies as a convenient means of communication with you.

    Does your child understand the cost?

    Make sure your child understands the cost of having a cellphone.{#blank#}3{#/blank#} Some options to help control costs include prepaid and postpaid phones，setting a monthly budget for your child.

    How can you keep your child's phone usage safe and under control?

    Before you get your child a phone，you should discuss what it can be used for，rules he is expected to follow，and consequences if he fails to follow them.{#blank#}4{#/blank#}

    {#blank#}5{#/blank#}If you prefer to take an extra step towards monitoring his phone use，these application programs allow you to track your child's mobile activity.

A．Who needs a cellphone?

B．How can you determine whether or not to buy a cellphone for your child?

C．Also be sure that he can be trusted to stay within his limits from month to month.

D．You ask your child to make use of his cellphone for learning.

E．Also, educate yourself on what social media apps are popular with teens.

F．According to Pew Research Center, the average age is between 12 and 13.

G．For example, is the phone only to be used to call family, or can it be used socially?

    Why do some people feel obliged to do the craziest things, while most of us are happy to sit on the sofa and watch their exploits on TV? Robin Styles ponders(考虑)this question.

    Generally, we love to watch someone's bravery and drama--a single person against the wilds of nature, testing their endurance beyond belief. And our pleasure is greater because we live a comfortable and increasingly risk-free life, where the greatest test of endurance is getting to work through the rush hour. {#blank#}1{#/blank#}However, there are countless ways to test the limits of your endurance, if you should wish to do so, by attempting something unpleasant, uncomfortable or just plain dangerous.

    American Lynne Cox swims in sub-zero temperatures through the planet's most dangerous oceans wearing only a swimsuit--for fun! According to Lynne, there is always something driving her on. At age 9, when she was swimming in an outdoor pool one day, a violent storm blew up, but she refused to get out of the pool. Something make her carry on. Then she realized that, as the water got colder and rougher, she was actually getting faster and warmer, and she was really enjoying it. At age 14, she broke her first endurance record. Years later, experts discovered that Lynne has a totally even layer of body fat, like a seal. {#blank#}2{#/blank#}

    The famous British explorer, Sir Ranulph Fiennes, has led many major expeditions (远征) in the extreme cold, including walking right round the Arctic Circle. He has also led expeditions in the extreme heat, and discovered the Lost City of Ubar in the Omani desert. {#blank#}3{#/blank#}Sir Fiennes has said, "If I am getting sick, I find a very powerful way of conquering it is to know that my father would have definitely done it."

    {#blank#}4{#/blank#}There is probably no such thing as a "normal" adventurer. Unsurprisingly, risk-takers tend to be single-minded and unusually determined people who hate the stability and routine that most people prefer. They tend to take risks for the "fun" of it. The excitement becomes addictive, and they want more and more of it. Ordinary life seems boring in comparison.

A. She is perfectly made for doing what she does, it seems.

B. Adventurers are clearly different from the rest of us.

C What she did was really beyond our imagination.

D. It seems that many adventurers spend their lives trying to live up to the image of a parent.

E. And most of us would prefer it to remain that way.

F. Many adventurers have amazed the world with their extraordinary skills.

My students and I were ready for a challenge — a trip to Costa Rica. As we were waiting at the airport, we talked about our hopes and fears for our ten-day trip. My students worried about homesickness and felt uneasy with their homestay families. But strange foods or meeting new people didn't concern me. What terrified me was the best part of the trip — a zip lining (滑缆绳) flight over the jungle valley bordering Arenal Volcano. I made a secret pact (协议) with myself to find an excuse to get out of it at the last minute.

    When the fateful day arrived, we got to the peak to enjoy the breathtaking view of the volcano. When seeing the activity, my students raised a cheerful shout. How I wished I had had the same feeling as them. However, I was afraid of heights.

    My student Eileen sidled up to me. Her face was pale. "I'm scared," she whispered. "Will you stay back with me?" Here was my chance! I could get out of zip lining and still save face!

    "I'm scared, too," I said quietly.

    "Yeah," she said. "I thought you would be the right person to ask because you are really white, and you are sweating." Her words woke me up, and something clicked into place. If I couldn't step outside of my comfort zone, how could I ask the kids to do so?

    "Maybe we should give it a try," I said. I felt a little sick, but I couldn't believe my body was actually moving toward the launch point.

    "Come on," I said.

    "OK," she agreed.

    Eileen zipped past me, screaming with fear or delight, which I was not sure of. Once she was across, I followed. The attempt was not as terrible as I had thought. From that moment on, I knew there was nothing to fear as long as I walked out of my comfort zone and had a try.
