The Canadian red and white maple leaf (枫叶) flag is officially called the National Flag of Canada. The Canadian flag shows a stylized red maple leaf with 11 points on a white background, with red borders down each side. The Canadian flag is twice as long as it is wide. The white square containing the red maple leaf is the same width as the flag.

    The red and the white used in the National Flag of Canada were proclaimed the official colors of Canada in 1921 by King George Ⅴ. Although the maple leaf did not have its official status as a symbol of Canada until the announcement (宣告) of the national flag in 1965, it had historically been used as a Canadian symbol, and was used in 1860 in decorations for the visit of the Prince of Wales to Canada. The 11 points on the maple leaf have no special significance.

    In the early days，the Royal Union Flag，or the Union Jack, was still flown in British North America. In 1925 and again in 1946, the Canadian Prime Minister Mackenzie King tried to get a national flag of Canada adopted, but failed. In 1964，Prime Minister Lester Pearson appointed a 15-member, all-party committee to come up with a design for a new flag. The committee was given six weeks to complete its task.

    The committee studied 2,000 submitted(提交的) designs as well as 3,900 that had been gathered as a result of the 1946 committee's study. Those designs with a chance of being accepted were given to the full committee for further study.

    The suggestion of a red and white single maple leaf design for the Canadian flag came from George Stanley, a professor at the Royal Military College. After a heated discussion, they finally decided on his suggestion.

    When Steve Jobs was born on Febuary24,1955, in San Francisco , California, his unmarried mother decided to put him for adoption because she wanted a girl. So in the middle of the night, his mother called a lawyer named Paul Jobs and said, “We have an unexpected baby boy; do you want him?” But his mother told his future parents to promise that they would send Jobs to college. After Steve Jobs graduated from high school, he went to college but decided to drop out because it was so expensive that he had to sleep on the floor in his friends' rooms.

At 20, he and a friend(Steve Wozniak) started a company in a garage on April 1, 1976. Jobs named their company —-Apple in memory of a happy summer he had spent as an orchard (果园) in Oregon.

    After 10 years of hard time and failures, starting from two kids working in a garage, Apple computer eventually grew into a big company with over 4000 employees.

    At 30, Jobs , however, was fired from the company he co-founded. But after he had to leave the company, Apple was under heavy pressure from rival (对手) Microsoft and in 1996 posted billions of dollars in losses. Apple needed Steve Jobs and he was appointed as Apple' CEO in1997. Under his leadership, Apple returned to profitability and introduced new products such as the iPhone and the iPod.

    Steve Jobs once said, “Sometimes life hits you in the head with a brick, Don't lose faith. I'm convinced that the only thing that kept me going was that I loved what I did. You've got to find what you love. If you haven't found it yet, keep looking.

    Many people believe that language belongs to human beings. However, cats have developed a language not for each other, but for the human beings who have them as pets.

    When communicating with each other, cats “talk” with a system of signals. Their tails, rather than any kind of “speech”, act as an important way to express themselves. They also touch each other to express s their feelings. With other cats, they will use their voices only to express pain. Unbelievable, all of that changes when a human walks into the room. Cats use many different kinds of vocal (声音的) expressions when they communicate with a person. Since these vocal expressions are not used to communicate with other cats, it seems that cats developed this “language” to communicate with their human owners.

    This fact is shown more clearly when watching rooms that have only one cat and those with several cats. An only cat is usually very vocal, since the only creature(动物)around with whom the cat can communicate is its owner. Cats with other cats, though, are much quieter. If they want to have a conversation, they only need go to other cats and communicate in their natural way.

    Since cats learned to meow(喵喵叫)for the only purpose of communicating with human owners should take the time to learn what their different meows mean. If an owner knows, to name just a few examples, which meow means the cat is hungry, which means the cat wants to be petted, and which means the cat wants to have a little “conversation”, the relationship between cat and owner will be closer.

    How often do you exercise? A new study found that most kids aged 12 to 15 weren't getting enough physical activity. The results were based on about 800 kids. As part of the study, the kids tracked and reported on their own activity levels, and took physical exams.

    U. S. fitness guidelines suggest an hour or more of physical activity every day. According to the study, only 1 in 4 U.S. kids get enough physical activity.

    "It's certainly worrying to see that our kids have such a limited amount of physical activity each day," said Dr. Stephen Pont. He is an expert on children's health.

    Few kids in the study met the guidelines on physical activity that raises the heart rate and makes people breathe harder. Overall, about 25% said they got an hour of that kind of exercise every day. Kids also reported on which activities they did most often outside of school gym class--basketball for boys and running for girls.

    The study found that fat teenagers were less active than normal-weight girls and boys. Fat girls were slightly less active than normal-weight girls, but levels were similar among overweight and normal-weight boys. The study also said that the percent of fat children aged 2 to 19 was 17%, or about 12.5 million kids.

    "There's always room for improvement," said Tala Fakhouri, who was the leader of the study. She also said the results provide useful information to help with fitness campaigns such as Let's Move, which was initiated by Michelle Obama in 2010. To inspire kids to eat right and get in shape, Michelle visits schools and holds exercise events. She also calls on schools to offer regular gym classes.

    The study also found kids who get physical education at school may get better grades.

Many people influenced various aspects of my life, based on their personal characteristics, accomplishments, and values. I have been fortunate to have had numerous teachers and professors who I respect for their patience and intelligence. There are artists that have inspired me by their natural talents and original creativity. I value many political leaders, who have inspired me by their contributions to society, and their ability to change our futures. But of all the people I have known in my life, the person I admire most is my father.

As the youngest girl in my family, I always considered myself to be "Daddy's little girl". While I grew up, it always made me sad to see so many of my friends and neighbors without a father or father-like figure around. This helped me appreciate how my father always takes an interest in his children's lives. In every aspect of my life my father continuously pushes me to excel, so I could accomplish my work outstandingly among my people. Whenever I feel like giving up, or have a question or a concern, I know I can always call on him for advice. From him I have also learned that sometimes you have to put others' needs ahead of your own, but you should make sure you are not taken advantage of by others. His strength seems to be unbreakable during hard times, and he is extremely determined to accomplish anything he sets his mind on, no matter how tiny it is. I highly respect him for how he stands up for what he believes in, and will never back down. He is a very reserved man, but to everybody's surprise, he has a great sense of humor, and always knows how to put a smile on the faces of his wife, his children and his friends.

Living in his love and instruction, I am very proud of my father. He also professes how proud he is of his children, and is still there to support us in whatever we are involved in.
