The food we eat seems to have profound effects on our health. Although science has made enormous steps in making food more fit to eat, it has , atthe same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of cancer is related to the diet as well, especially cancer the colon . Different cultures are more prone to contract certain illnesses because of the food that is characteristic in these cultures. That food related to llness is not a new discovery. In 1945 , government researchers realized that itrates and nitrites, commonly used to preserve color in meats, and other food dditives, caused cancer. Yet, these carcinogenic additives remain in our food, nd it becomes more difficult all the time to know which things on the pack ging labels of processed food are helpful or harmful.The additives which we eat are not all so direct. Farmers often give penicillin to beef and poultry, and because of this, penicillin has been found in the milk of treated cows. Sometimes similar drugs are administered to animals not for medicinal purposes, but for financial reasons. The farmers are simply trying to fatten the animals in order to obtain a higher price on the market. Although the Food and Drug Administration (FDA) has tried repeatedly to controlthese procedures, the practices continue. 48. What is the main topic of the passage? A. Food and our health B Food and additives C. Food and cancer D Food and culture 49 All of the following statements are true EXCEPT_______. A Forty percent of cancer is caused by problems related to food. B Researchers have known about the potential danger of food additivesfor many years C. We eat some of the food additives directly and some indirectly D Drugs are always given to animals for medicinal purposes 50. Why do farmers give drugs to their animals? A. to speed up the growth of animals B To make theanimals fatter C to make the animals ’ meat fit to eat D To make the animals’ meat rich in nutrients 51. It can be inferred from the passage that_________. A scientist have made all the food fit to eat B only in recent years have people found that the food is related to one’s illness C all kinds of cancer are related to the diet D some additives are harmful to our health 52. The word “ this ”in the second sentence of paragraph 2 most probablyrefers to __________. A farmer B penicillin C beef and poultry D the fact that farmers often give penicillin to a beef

Passage 3 Questions 11 to 15 are based on the following passage: The idea of a special day to honor mothers was first put forward in America in 1907. two years later a woman, Mrs. John Bruce Dodd, in the state of Washington proposed a similar day to honor the head of the family—the father. Her mother died when she was very young, and her father brought her up. She loved her father very much. In response to Mrs. Dodd’s idea that same year—1909, the state governor of Washington proclaimed (宣布) the third Sunday in June Father’s Day. The idea was officially approved by President Woodrow Wilson in 1916. in 1924, President Calvin Coolidge recommended national observance of the occasion “to establish more intimate (亲密) relations between fathers and their children, and to impress upon fathers the full measure of their obligations.” The red or white rose is recognized as the official Father’s Day flower. Father’s Day took longer to establish on a national scale than Mother’s Day, but as the idea grained popularity, tradesmen and manufacturers began to see the commercial possibilities. They encouraged sons and daughters to honor their fathers with small thank-you presents, such as a tie or pair of socks, as well as by sending greeting cards. During the Second World War, American servicemen stationed in Britain began to request Father’s Day greeting cards to send home. This generated a response with British card publishers. Though at first the British public was slow to accept this rather artificial day, it’s now well celebrated in Britain on the third Sunday in June in much the same way as in America. Father’s Day seems to be much less important as occasion than the Mother’s Day. Not many of the children offer their fathers some presents. But the American fathers still think they are much better fated than the fathers of many other countries, who have not even a day for their sake in name only. 11. When did Father’s Day officially begin to have national popularity? A. 1907 B. 1909 C. 1916 D. 1924 12. Who first started the idea of holding the Father’s Day? A. Mrs. John Bruce Dodd B. Mrs. John Bruce’s Mother C. The government of Washington. D. Some businessmen. 13. What flower will be popular on Father’s Day? A. Lily B. Water Lily C. Red rose or white rose D. Sunflower. 14. Which statement is true, a according to this passage? A. It took even longer for Mother’s Day to gain national popularity. B. The businessmen helped to make Father’s Day popular. C. Father’s Day is only celebrated in America. D. Father’s Day is only a trick of the businessmen to make money. 15. What was the first reaction of the British publishing towards Father’s Day? A. They thought highly of it and accepted it at once. B. They just accepted it at once without any hesitation. C. They just thought it a joke. D. They thought it was too artificial and took a long time to accept.

Passage 4 Questions 16 to 20 are based on the following passage: The new global satellite communications systems will offer three kinds service, which may overlap in many different kinds of receivers. VOICE. Satellite telephones will be able to make calls from anywhere on the Earth to anywhere else. That could make them especially useful to remote, third world villages (some of which already use stationary satellite telephones), explorers and disaster-relief teams. Today’s mobile telephones depend on earth-bound transmitters, where technical standards vary from country to country. So business travelers cannot use their mobile phones on international trips. Satellite telephones would make that possible. MESSAGING. Satellite massagers have the same global coverage as satellite telephones, but carry text alone, which could be useful for those with laptop computers. Equipped with a small screen like today’s papers, satellite massagers will also receive short messages. TRACKING. Voice and messaging systems will also tell their users where they are to within a few hundred meters. Combined with the messaging service, the location service could help rescue teams to find stranded adventurers, the police to find stolen cars, exporters to follow the progress of cargoes, and haulage companies to check that drivers are not detouring the pub. America’s military Global Positioning System (GPS) satellite will provide better positioning information to anyone who has a receiver for their signals, but GPS does not carry messages, so such a receiver cannot be used on its own for tracking or rescue. By the mid-1990s, GPS receivers will be able to tell people where they are to within 70 meters anywhere in the world, and to within a meter or so in areas where the service is supplemented by ground-based transmitter. 16. Global satellite communications systems will be useful to . A. laptop computer users B. remote villages C. disaster-relief teams D. all above 17. Satellite telephone will make . A. business travelers use mobile phones on international trips B. possible calls from anywhere on earth to anywhere else C. explorers happy D. all above 18. Which of the following is true? A. The positioning precision of the voice system is better than that of GPS. B. The positioning precision of GPS is Better than that of the voice system. C. The positioning precision of the messaging system is better than of GPS. D. The positioning precision of voice system is better than that of the messaging system. 19. What can we say about the new global satellite communications systems? A. They are widely used. B. They are very helpful. C. They are costly. D. Both A and B. 20. Which of the following may be the best title for the passage? A. Global Satellite Communications B. New Voice and Messaging System C. New Generation Satellite D. Always in Touch
