[Q]: Article: Roughly speaking, teachers in traditional education may feel that students are too young to know much about the world, and have to be told what to do most of the time. By contrast, open education offers teachers quite different feelings. Students are expected to be responsible for their own education--to discover subjects by themselves instead of being made to study them. This way of teaching allows the students to grow independently and to develop their own interests in many subjects. Some students who do badly in a traditional classroom will be happier in an open classroom and enjoy learning. They will not have to worry about grades or rules at all. However, many students won't do well in an open classroom. For these students, they will do little in school if there are too few rules. They will not make good use of open education, which is so different from traditional class, because they may have a problem getting used to making so many choices on their own. For them it is important to have some rules to direct them. They may worry about the rules even when there are no rules. In addition to that, some traditional teachers do not believe in open education and do not like it either. Since both of some good points and bad points of the open education have been explained clearly, you may have your own opinion on the issue. Personally, I think that the concept of open education is good only in theory. In actual fact, it may not work very well in a real class or school. I believe, most students, but of course not all students, need some structure in their classes. They may want and need to have rules. In some cases, they must be made to study some subjects. Many students are pleased to find subjects they have to study interesting. They would not study those subjects if they did not have to.
Question: Open education allows the students to _ .
Options: (A) grow as the educated (B) be responsible for their life (C) discover subjects outside class (D) develop their own interests

[Q]: Article: Duke Ellington is known as one of the most important composers of his time, and his work has been enjoyed for more than 80 years by music lovers all over the world. During his lifetime Ellington turned musical sounds into many compositions, mostly in the style known as jazz. The Early Years Edward Kennedy Ellington was born in 1899 in Washington, D. C. It wasn't until Ellington was a teenager that his interest in music grew. He taught himself to play the piano by listening to local piano players. Sometime around 1916 Ellington began playing the piano at high school parties. Ellington realized that he enjoyed entertaining people with his music. He soon became a very popular musician, playing at parties and other events in the Washington area. Young adults seemed especially delighted by the modern pieces he composed. Success in New York In 1923, when Ellington was almost 24 years old, he joined The Washingtonians, a five-piece group of musicians in Washington, and became the group's leader in early 1924. In 1927 Ellington and his orchestra won an engagement at Harlem's famous Cotton Club. For the next three years, his orchestra played at the Cotton Club nearly every night. The Influence of the Cotton Club Working at the Cotton Club encouraged Ellington's creativity. Since the shows changed every six months, he was challenged by the need to continually develop new material. He had to compose a wide variety of music to accompany the various acts in the Cotton Club shows and to adapt that music to the strengths and weaknesses of the players in his orchestra. By 1928 the popular nightspot began radio broadcasts. From the broadcasts Ellington and his orchestra gained a national reputation. On the Road As Ellington's popularity increased, he realized that his orchestra could do well on concert tours. They left the Cotton Club in 1931 and toured America and Europe almost continually for the next 43 years. In addition to touring, Ellington made recordings and continued to compose music. Duke Ellington played the piano, composed music, and led his famous orchestra for more than 50 years, until his death in 1974. Music lovers all over the world agree that the large quantity of music he created will be enjoyed for many years to come.

[Q]: Article: For years, children in the industrial areas of Europe and America seldom left their smoky cities to see the beauties of the countryside. This was not because the woods and fields were always far away, but because they were too far from the city to permit people to make a day trip between morning and nightfall. In 1907, a young German schoolmaster had an idea which changed this state of affairs. He decided to turn his little schoolhouse into a dormitory for the summer holidays. Anyone who brought his sleeping bag and cooking equipment along could stay there for a very small quantity of money. The idea was a success. A few years later, the schoolhouse was much too small to hold the many young people who wanted to stay there. As a result, a dormitory was set up in an old castle nearby. This was the first Youth Hostel. Today, young students and workers of every country can meet in the hostels and get to know each other. When young people arrive at a hostel, they have only to show their card of membership in a hostel organization in their own country. This card will permit them to use the facilities of hotels all over the world for a very low price. Often, at the evening meal, a group of boys and girls from various parts of the country or the world will happen to meet at the same hostel. They may put their food together and prepare a dinner with many kinds of dishes. Sometimes a program will be organized after the meal, with dances, songs, or short talks followed by a question period. One can learn a lot of things about other places, just by meeting people who come from those places. For this reason, a few weeks spent "hosteling" can be just as useful a part of one's education as classes in school.
