The United States has always been a country of many cultures. Before Europeans came to North America, many groups of Native Americans lived here. Different Native American groups had different cultures. The first Europeans in the United States were from England and Holland, but immigrants came from all European countries. Many people also immigrated from Asia and Africa. Sadly, many Africans were brought to the United States as slaves. Many immigrants come from Latin America too. Today, the United States has people from more cultures than ever.

    In the 19th century, people spoke of the United States as a “melting pot.” People thought that all immigrates should forget their native cultures and languages and become English-speaking Americans. They felt that people should assimilate-join American culture. However, not everyone wanted to assimilate completely. Many people tried to keep parts of their cultures, such as foods, customs, and languages. However, their children often forgot their parents' or grandparents' language. But most Americans, even those whose families have been here a long time, can tell the countries their relatives came from. And of course, new immigrants take great pride in their curare and language.

    For all of these reasons, melting pot is no longer a good way to describe the United States. Instead, people now call the United States a “salad bowl.” They say salad bowl because in a salad, you can still see all of the individual parts (lettuce, tomato, and so on), but all the different parts mixed together and begin to take on the flavor of one another.

A handsome middle-aged man walked quietly into the cafe and sat down. Before he ordered, he couldn't help but noticed a group of younger men at the table next to him. It was obvious they were making fun of something about him and it wasn't until he remembered he was wearing a small pink ribbon (丝带) on the lapel (翻领) of his suit that he became aware of what the joke was all about.

    The man pretended not to notice it, but the whisper and laughter began to get to him. He looked one of the rude young men straight into the eye, placed his hand beneath (在…下方) the ribbon and asked, “This?”

    With that the young men all began to laugh out loud. The man he spoke to said, “Hey, sorry, man, but we were just commenting on how pretty your little pink ribbon looks against your blue jacket!”

The middle-aged man calmly invited the joker to come over to his table, and politely seated him. As uncomfortable as he was, the young guy had to, not really sure why. In a soft voice, the middle-aged man said, “I wear this ribbon to bring awareness about breast cancer. I wear it in my mother's honor.”

     “Oh, sorry. She died of breast cancer?”

“No, she didn't. She's alive and well. But her breasts nourished (抚养，滋养) me as a baby, and were a soft resting place for my head when I was scared or lonely as a little boy. I'm very grateful for my mother's breasts, and her health.”

     “Umm,” the young replied, “yeah.”

     “And I wear this ribbon to honor my wife,” the man continued.

“And she's okay, too?” the young guy asked.

“Oh, yes. She's fine. Her breasts have been a great source of loving pleasure for both of us, and with them she nurtured (养育，培育) and nourished our daughter 23 years ago. I'm grateful for my wife's breasts, and her health.”

     “Uh, huh. And I guess you wear it to honor your daughter, also?”

“No. It's too late to honor my daughter by wearing it now……”

Shaken and ashamed, the young guy said, “Oh, I'm so sorry, mister.”

“So, in my daughter's memory, too, I proudly wear this little ribbon, which allows mo the opportunity to enlighten (启发，教导) others. And here…” With this, he reached in his pocket and handed the young roan a little pink ribbon. The young guy looked at it, slowly raised his head and asked, “……?”

    How much weight a baby gains during its first month could determine its IQ, new research found. The study found that children who gain more weight, and whose heads grow quickly during the first month of life, tend to have a higher IQ when they start school.

    Researchers at the University of Adelaide, in Australia studied 13, 800 children who were born at full-term. They found that those who put on 40% of their birth weight in the first four weeks had an IQ 1.5 points higher than those who only put on 15% of their birth weight. Those who experienced the biggest growth in head circumference(头围) also had the highest IQs by the age of six.

    "Head circumference is an indicator of brain volume, so a greater increase in head circumference in a newly-born baby suggests more rapid brain growth, "says the author of the study, Dr. Lisa Smithers. She added, "Overall, newly-born children who grew faster in the first four weeks had higher IQ scores later in life. Those children who gained the most weight scored especially high on the verbal IQ at age 6. This may be because neural (神经的) structures for the verbal IQ develop earlier in life, which means the rapid weight gain during the first month could be having a direct cognitive benefit for the children."

    Previous studies have shown the association between early postnatal (产后的) diet and the IQ, but this is the first study of its kind to focus on the IQ benefits of rapid weight gain in the first month of life. Dr. Lisa Smithers says the study further highlights the need for successful feeding of newly-born babies." We know that many mothers have difficulty establishing breastfeeding in the first week of their babies' life,” Dr. Lisa Smithers said.

    "The findings of our study suggest that if babies are having feeding problems, there needs to be early intervention(干预) in the management of that feeding."

    Author Avi, winner of a Newbery Award, a Scott O'Dell Historical Fiction Award, and several Boston Globe-Horn Book Awards, may have seen his first children's book published in 1970, but that doesn't mean he's lost his talent for connecting with young fans.

    The American writer, born in 1937, agrees that getting involved with his readers is one of the key reasons he keeps writing, and that he's been fortunate enough to hear directly from readers about the impact (影响) his books have had. “I have been touched many times by readers who find some special connection between their lives and something I have written: the Danish girl who read something of mine in Danish, and struggled to communicate that in her poor English; the autistic (自闭症的) boy who somehow found something meaningful about my books that reached his own inner life; the women who have told me how important The True Confessions of Charlotte Doyle was to them when growing up."

    Beyond his fans' questions about the characters he's created, the writer's most commonly heard question may be about his own use of the single name “Avi." “As a young adult, I was a reader of French literature, which has that one name tradition: Moliere, Racine, Anouilh, Gide, and so on," he explains. “Avi was given to me by my twin sister when we were very young children, and it stuck. Then my family discouraged me from taking up writing as a career because they considered my writing poor. By using Avi, I was showing my determination to them."

    Although he believes－and has the awards to show－that his writing skills have improved, writing still doesn't come easily to him, despite having over sixty books to his credit. “I never studied writing in any formal sense. I taught myself to write by reading, and by imitating what I was reading," he says.

    The writing task may be tough, but the payoff is big. “To create, share, and support the gift of reading and literature, is to give young people the gift of many worlds, within and without," Avi states.

    Li Hua is currently studying at Cambridge, UK. She has bought a bicycle and is worried about security. Her friend, Kate, found this article and sent it to her.

    Introduction

    A lot of crime is against bicycles. About 150, 000 bicycles are stolen every year and most are never found. You can prevent this happening by following a few careful steps.

    Basic Security

    Do not leave your bicycle in out-of-the-way places. Always lock your bicycle when youleave. Secure it to lampposts or trees. Take off smaller parts and take them with you, for example lights and saddlesleave（车座）.

    Locks

    Get a good lock. There are many different types in the shops. Buy one that has been tested against attack. Ask for a recommendation from a bike shop.

    Marking

    Security marking your bike can act as a deterrent to a thief. It can also help the police find your bicycle. It should be clearly written and include your postcode and your house or flat number. This will provide a simple way to identify your bicycle.

    Registration (登记)

    There are a number of security companies who will help mark your bicycle for you. They will then put your registration number and personal details on their computer database. Then if your bicycle is found it will be easy to contact you.

    Finally

    Keep a record of the bicycle yourself: its maker, model and registration number. You can even take a photograph of it. This will prove the bicycle belongs to you.

    What would you like to be when you grow up? A teacher? A doctor? An astronaut? What do you need to do to achieve your dream job?

    Perhaps you think that studying well and then going on to work hard will get you the successful career you want. We are constantly taught that our hard work will eventually pay off.

    But a government survey has shown that hard work is not the only thing that will help you to move up the ladder. Two thirds of people believe that who you know matters more than what you know when it comes to social activity. So are the connections that you have more important than your education?

    Seventy-six percent of the people in the survey believed that family background is important in influencing your chances of success. They believe that if you are privileged from birth, you are more likely to have a successful career, especially if your family is wealthy.

    Even if you don't have a privileged background, the people you know can still make a difference to your career. Networking is a skill which is encouraged by many career advisers. Some companies run networking workshops to try and encourage staff to meet other people, to communicate and build relationships. It's a valuable skill.

    But the survey also showed something quite interesting. Although most people believed that networks are more important than education, many people put their own career success down to talent, rather than background. 41% of the people said that their parents' income had influenced their life, but at the same time, another 41% believed that they had achieved their own success.

    So which is more important, what you know or who you know? It seems that by working hard and making lots of connections, the answer may be that both are very important.
