Many critics worry about violence on television, most out of fear that it stimulates viewers to violent or aggressive acts. Our research, however, indicates that the consequences of experiencing TV's symbolic world of violence may be much more far-reaching. We have found that people who watch a lot of TV see the real world as more dangerous and frightening than those who watch very little. Heavy viewers are less trustful of their fellow citizens, and more fearful of the real world. Since most TV "action-adventure" dramas occur in urban settings, the fear they inspire may contribute to the current flee of the middle class from our cities. The fear may also bring increasing demands for police protection, and election of law-and-order politicians. While none of us is completely dependent upon television for our view of the world, neither have many of us had the opportunity to observe the reality of police stations, courtrooms, corporate board rooms, or hospital operating rooms. Although critics complain about the fixed characters and plots of TV dramas, many viewers look on them as representative of the real world. Anyone who questions that statement should read the 250,000 letters, most containing requests for medical advice, sent by viewers to "Marcus Welby, M.D." --a popular TV drama series about a doctor-- during the first five years of his practice on TV. Violence on television leads viewers to regard the real world as more dangerous than it really is, which must also influence the way people behave. When asked, "Can most people be trusted?" the heavy viewers were 35 percent more likely to choose "Can't be too careful." Victims, like criminals, must learn their proper roles, and televised violence may perform the teaching function all too well. Instead of worrying only about whether television violence causes individual displays of aggression in the real world, we should also be concerned about social reality. Passive acceptance of violence in the face of injustice may result from far greater social concern... Which of the following is NOT among the consequences of watching TV too much? A) Distrusting people around. B) Moving into rural areas. C) Turning to the police for protection. D) Holding more elections.

Sometimes successful health campaigns can have quite unexpected reactions. The years of warnings about skin cancer mean that Britons are happy to cover themselves in sunscreen or stay out of the sun altogether, but it also means that most of us are not getting enough vitamin D. Scientists announced yesterday that Britons need to increase to three times the amount of vitamin D they get per day. They called on food producers to fortify their products with more of the vitamin and suggested people should consider taking supplements  to keep levels up. They also suggested getting out in the sun for short periods more often, but they warned against "sun bingeing". The government does not publish official advice on the amount of vitamin D people should take due to a lack of research, says Dr Birgit Teucher of the Institute for Food Research. But in the US, the government recommends 5 micrograms a day. By that count, Dr Birgit Teucher said that around 90% of Britons between 19 and 64 would be lacking in the vitamin because they only took around 3 micrograms a day. Vitamin D is important for absorption of calcium by the body, which is needed for healthy teeth and bones. A lack of it can lead to serious diseases in both children and adults. The vitamin can be found in some foods but it can also be obtained from chemicals in the skin reacting to sunlight. Dr Barbara Boucher said adults should get 5 to 25 micrograms a day. Shortage of vitamin D may be linked to diseases such as muscle weakness, high blood pressure and rickets . Dr Birgit Teucher gave several reasons for the lack among Britons. Increasing numbers of office-based jobs mean a lack of exposure to the sun; and the rise of becoming overweight means that vitamin D--which is fat soluble is increasingly stored in body fat, where it cannot be accessed readily. Professor Brian Wharton of the Institute of Child Health said that children in particular needed to have enough vitamin D to prevent rickets. Professor Graham Bentham, an environmental scientist at the... From the passage, we can conclude  _  . A) the babies who were only breast--fed certainly need to take vitamin D supplements B) a large quantity of vitamin D stored in body fat is the primary reason for being overweight C) the sunlight can produce adequate vitamin D that the body needs all year round D) vitamin D is vital for the body to absorb calcium needed for healthy teeth and bones

A new study has found evidence of aggressive   behavior in children who drink four or more servings of soft drinks every day. Information for the study came from the mothers of 3,000 5-year-olds. Researchers asked the women to keep a record of how many servings of soft drinks their children drank over a two-month period. They were also asked to complete a checklist of their children's behavior. The researchers have found that 43 percent of the children drink at least one daily serving of soda, and 4 percent of the youngsters have even four or more sodas to drink every day. Shakira Suglia, a famous expert, says they've found that children who drink the most soda are more than twice as likely as those who drink no soda to show signs of aggression. "For the children who consume four or more soft drinks per day, we see more _ behaviors, which make them hard to get along well with others." The aggressive behaviors include destroying possessions belonging to others, taking part in fights and physically attacking people. The researchers have determined the link after considering factors like the child's age and sex. They have also considered other possible influence, such as whether the boys and girls are eating sweets or giving fruit drinks on a normal day. In addition, the researchers have examined parenting styles and other social conditions that may be taking place in the home. Researches are trying to find why young children who drink a lot of soda have behavior problems. An ingredient often found in soft drinks is caffeine, which helps to make people feel energetic. Doctor Suglia suggests that caffeine could cause the 5-year-olds to be more aggressive. Earlier studies of adults have found the highest sugar levels in those who carry weapons   and show signs of negative social behavior. What section of a newspaper is the passage probably taken from? A) Scientific Technology B) Science Fictions C) Social News D) Health Report

The Marches were a happy family. Poverty, hard work, and even the fact that Father March was away with the Union armies could not down the spirits of Meg, Jo, Amy, and Marmee, as the March girls called their mother. The March sisters tried to be good but had their share of faults. Pretty Meg was often displeased with the schoolchildren she taught; boyish Jo was easy to become angry; golden-haired schoolgirl Amy liked to show up; but Beth, who kept the house, was loving and gentle always. The happy days passed and darkness came when a telegram arrived for Mrs. March. "Your husband is very ill," it said, "come at once." The girl tried to be brave when their mother left for the front. They waited and prayed. Little Beth got scarlet fever   when she was taking care of the sick neighbor. She became very ill but began to recover by the time Marmee was back. When Father came home from the front and at that joyful Christmas dinner they were once more all together. Three years later the March girls had grown into young womanhood. Meg became Mrs. Brooke, and after a few family troubles got used to her new state happily. Jo had found pleasure in her literary efforts. Amy had grown into a young lady with a talent for design and an even greater one for society. But Beth had never fully regained her health, and her family watched her with love and anxiety. Amy was asked to go and stay in Europe with a relative of the Marches. Jo went to New York and became successful in her writing and had the satisfaction of seeing her work published there. But at home the bitterest blow was yet to fall. Beth had known for some time that she couldn't live much longer to be with the family and in the spring time she died. News came from Europe that Amy and Laurie, the grandson of a wealthy neighbor, had planned to be married soon. Now Jo became ever more successful in her writing and got married to Professor Bhaer and soon afterwards founded a school for boys. And so the little women had grown up and lived happily with their children,... It can be inferred from the passage that the March family had   _  . A) both happiness and sadness B) wealthy neighbors C) more girls than boys D) a lot of rich relatives
