Article: If you were walking around a supermarket and saw a woman with a shaved head, a ring through her nose, a tattoo design on her arm and she has a small child in her shopping _ , what would your opinion be? Do you think this kind of body decoration is attractive or ugly? Different people have different ideas. The following are some examples of body decoration from around the world. In many parts of Africa, it is thought that an attractive girl should have really shinny skin. On Bali, a little island in Indonesia, they believe that a beautiful woman or handsome man must have perfectly straight, flat teeth. The Balinese believe that teeth with pointed edges make you look like an ugly wild animal. So when a girl or boy becomes a teenager, he or she is taken to a special person in their village who will file off teeth points to make them smooth and flat. There is no anesthetic and this tooth filing is really painful. It is a kind of test. If you can stand it without screaming or crying too much, then you are thought ready to become an adult. In Myanmar, there is a small group of people who are called the "Papaung". They believe that a woman can only be really beautiful if she has a long neck. I mean a VERY long neck. Now you might think that you are either born with a long or short neck and that there's nothing whatever you can do about it. But you would be wrong! At around the age of 5, a Papaung girl has heavy metal rings fitted around her neck, tightly between the chin and shoulders. Each year more rings are added and very, very slowly their weight pushes the shoulders down, in this way making the neck look longer. A Papaung woman will wear her neck rings all her life, never once taking them off. So now I'm sure you will all agree that different people have different ideas about what is beautiful.

Options: (A) a person with straight, flat teeth looks ugly (B) a person with sharp teeth looks ugly (C) a teenager's teeth points must be filed off with anesthetic (D) no one will scream or cry when having his teeth points filed off

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

Article: In the Caucasus region of Russia, nearly 50 out of every 100,000 people live to celebrate their 100th birthday, and many don't stop at 100! By comparison, in America only 3 people in 100,000 reach 100. But these Russian old people aren't alone. The Pakistanis, who live high in the Himalaya Mountains, and the Ecuadorans of the Andes Mountains seem to share the secret of long life, too. These people remain healthy in body and spirit despite the passage of time. While many older persons in industrial societies become weak and ill in their 60s and 70s, some Caucasians aged 100 to 140, work in the fields beside their great-great-grandchildren. Even the idea of aging is foreign to them. When asked "at what age does youth end?"most of these old people had no answer. Several replied, "Well, perhaps at age 80." What accounts for this ability to survive to such old age, and to survive so well?First of all, hard physical work is a way of life for all of these long-lived people. They begin their long days of physical labor as children and never seem to stop. For example, Mr . Rustam Mamedov is 142 years of age. His wife is 116 years old. They have been married for 90 years. Mr. Mamedov has no intention of retiring from his life as a farmer. "Why?What else would I do?"he asks. All these people get healthful rewards from the environment in which they work. They all come from mountainous regions. They live and work at elevations of 1,660 to 1,000 meters above sea level. The air has less oxygen and is pollution-free. This reduced-oxygen environment makes the heart and blood vessel system stronger. Another factor that may contribute to the good health of these people is their isolation. To a great extent, they are separated from the pressures and worries of industrial society. Inherited factors also play some role. Most of the longest-lived people had parents and grandparents who also reached very old ages. Good family genes may, therefore, be one factor in living longer.
Question: The example of Mr. and Mrs. Mamedov implies that some Caucasians aged 100 to 140 _ .
Options: (A) become weak and hopeless (B) are too old to work in the fields (C) benefit from physical work (D) are still working in the fields
C
