The Nobel Prize is a series of awards given to people excelling (胜出) in scientific,  literary and social fields. The Nobel Prizes have been awarded annually since 1901 to those who stand out in their field of expert knowledge or skill，and specifically those who make great progress in the advancement of these fields. The best known prize is the Nobel Peace Prize，but there are also awards for physics，chemistry，medicine and literature. Nobel Prize nominees arenˈt told about their nomination(提名)，only the winners are announced publicly. Winners are announced every October and the ceremony is in December. Each prize is made up of a medal，a personal diploma and a cash award of 10 million Swedish kronor(1.4 million US dollars)．

If you want to win one of these awards，you must stand out in your field and earn the

nomination. Therefore，first focus your studies in one of the Nobel Prize fields. The categories are peace，physics，chemistry，physiology，economics and literature. Get a background education in one of these fields.

Then find a world problem and try to solve it. Curing diseases，discovering new things or

even just attempting to fix a problem may attract the attention of a Nobel nominator. Find one issue you think you can solve and work on that. It may take years before your work gets anywhere，but you should stay focused and work toward a solution.

Network(沟通)with others in your field. Since you canˈt nominate yourself for a Nobel Prize，you must make other people know your work. Attend conferences and write articles to newspapers and magazines about your work. The more you make your work known，the better your chances of earning a nomination. If your work gets the attention of a Nobel Prize nominator，he or she may nominate you.

Ignore frustration. It can take years or even decades for your work to gain recognition，so

donˈt give up if you havenˈt won a prize. In some scientific categories the Nobel Prize selection

committee actually delays giving a prize for several years，just in case a theory is discredited(不足信的). Keep at your work and realize that even if you donˈt win a Nobel Prize youˈll still be doing the world some good.

MARTIN Luther King Day fell on Janthis year, the third Monday in January. It would just have been a one-day holiday for me had I not taken part in the march held near St. Louis Park to support equality (平等) for African Americans.

It was four o’clock in the afternoon when Bridget, my host mother, and I arrived at the local church where the march started. Hundreds of people had already gathered together for the march. Among them there were not only African Americans, but also large numbers of supporters from many different backgrounds. There were black boys playing the saxophone (萨克斯管) and drums, white girls holding up banners (横幅), old couples in “Black Lives Matter” T-shirts and priests (神父) from the church in white robes (长袍). Some of them were Catholic (天主教徒), some were not, yet they all came together to support what they thought was right and just.

This march was full of positive energy and high spirits. It started when a young black lady of about years old from the local church sang a song and the group joined in. Whistles (口哨) and timbrels (手鼓) could be heard along with the singing and clapping.

For a moment, I felt shocked and confused. I used to think of the fight for equal rights as a hard struggle, but these people showed the world their optimism (乐观) with smiles and music. I couldn’t help joining them, saying from the bottom of my heart that black lives matter. While we were marching, the passers-by waved hands at us, gave us thumbs-up, and some cars even made noise with their horns (号角) to support us. Bridget and I left the march about ten minutes later, but it was said to last over half an hour.

The march is only one of the many examples that show how much Americans care about human equality. High school students are asked to read books like To Kill a Mockingbird to learn about the lives of African Americans. My host parents even chose my host brother’s school because of the children of many different backgrounds that go there. Human equality has indeed become common sense in Americans’ daily lives and education.

Doctor Seuss was the name used by Theodor Seuss Geisel, who was famous because of the books he wrote for children. They combine funny words, funny pictures, and social opinion.

Theodor Geisel was born in Springfield, Massachusetts in 1904. After graduating from Dartmouth College in 1924, he spent a year studying literature(文学) at Oxford University in England. When he returned to the United States in 1927, he hoped to become a writer of serious literature. But the economic depression(经济萧条) in the United States delayed his dreams of becoming a serious writer. In 1937, he wrote his first book for children, which is called “And To Think I Saw It on Mulberry Street.” However, a number of publishers refused to accept it. They said it was too different from ordinary books. A friend finally published it. Soon other successful books followed. Over the years he wrote more than forty children’s books, which were fun to read. Yet his books sometimes dealt with serious subjects including equality, responsibility and protecting the environment.

Doctor Seuss had a strong desire to help children. In 1954, Life magazine published a report about school children who could not read. The report said many children’s books were not interesting. Reading the report, Doctor Seuss decided to write books that were interesting and easy to read. To make his book easy to read, he used words with the same ending sound, like fish and wish.

In 1957, Dr. Seuss wrote “The Cat in the Hat”, in which he used less than two hundred twenty-five words. This was the number of words a six-year-old should be able to read. The book was an immediate success. Children loved it. Their parents loved it, too. Today many adults say it is still one of the stories they like best. The success of the book made him want to write more books for children. He started a series called Beginner Books, which remain well liked among children today.

In 1984, Mr. Geisel won a Pulitzer Prize for children’s literature. At that time he had been writing children’s books for almost fifty years. He was honored for the education and enjoyment his books provided American children and their parents, and his influence remains through the books he wrote.  Experts say his books helped change the way American children learned to read.
