  American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like. 

Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard.

  Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students' résumés look better to employers if they list a few extracurricular activities.

  Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower-income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives.

  Movies about college life usually have characters that are extreme in some way: super athletic, super intelligent, super wealthy, super glamorous, etC. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all.

  So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you.

A. not high

B. unlimited

        The Roman alphabet took thousands of years to develop, from the picture writing of the ancient Egyptians through modifications by Phoenicians, Greek, Romans, and others. Yet in just a dozen years, one man, Sequoyah, invented an alphabet for the Cherokee people. Bom in eastern Tennessee, Sequoyah was a hunter and a silversmith in his youth, as well as an able interpreter who knew Spanish, French and English.

        Sequoyah wanted his people to have the secret of the “talking leaves” as he called his books of white people, and so he set out to design a written form of Cherokee. His chief aim was to record his people’s ancient tribal customs. He began by designing pictographs for every word in the Cherokee vocabulary. Reputedly his wife, angry with him for his neglect of garden and house, burned his notes, and he had to start over. This time, having concluded that picture-writing was cumbersome, he made symbols for the sounds of Cherokee language. Eventually he refined his system to eighty-five characters, which he borrowed from the Roman, Greek, and Hebrew alphabets. He presented this system to the Cherokee General Council in 1821, and it was wholeheartedly approved. The response was phenomenal. Cherokees who had stmggled for months to leam English lettering school picked up the new system in days. Several books were printed in Cherokee, and in 1828, a newspaper, the Cherokee Phoenix, was first published in the new alphabet. Sequoyah was acclaimed by his people.

         In his later life, Sequoyah dedicated himself to the general advancement of his people. He went to Washington, D.C, as a representative of the Western tribes. He helped settled bitter differences among Cherokee after their forced movement by the federal government to the Oklahoma territory in the 1930s. He died in Mexico in 1843 while searching for groups of lost Cherokee. A statue of Sequoyah represents Oklahoma in the Statuary Hall in the Capitol building of Washington, DC. However, he is probably chiefly remembered today because Sequoias, the giant redwood trees of California, are named of him.

In the final version of the Cherokee alphabet system, each of the characters represents a

A. picture

B. sound

C. word

D. thought
