摘要: The author writes the passage mainly . A. to remind people of negative effects of juice B. to call on people to drink more juice C. to help people learn more about fruit and juice D. to persuade people to avoid junk juice containing various fruits B The earliest type of medicine in most cultures was the use of plants and animal parts. There is no actual record of when the use of plants for medical purposes first started, although the first generally accepted use of plants as healing medicine was described in the cave paintings discovered in France, which have been dated back to between 25000-13000 BC. The practice of medicine developed gradually, and separately, in ancient China, Egypt, India, Greece, Persia and elsewhere. Medicine as it is practiced now developed largely in the late 18th century and early 19th century in England, Germany and France, thanks to advances in chemistry as well as laboratory techniques and equipment. The new `scientific’ medicine (whose results are testable and repeatable) replaced medicine in earlier times, which was based on herbalism. The modern era really began with Robert Koch’s discoveries around 1880 of the transmission of disease by bacteria, and then the discovery of antibiotics thereafter. The 20th century witnessed major advances in the treatment of infectious diseases in western societies. The medical world is now developing medicine that targets one particular disease process. Thus medicine is being developed to reduce the side effects to the greatest degree and to treat cancer and long-term problems such as high cholesterol. Today’s medicine has evolved over thousands of years as each generation used and expanded the knowledge of earlier times. This will continue to happen, and it is impossible to say how medicine will develop over the next hundred years. Our understanding of human genomewill lead to fresh treatments and new discoveries may open the door to unimaginable advances in medicine.

Fruit or juice, which is nutritionally superior? This is almost the same as the age-old question: The chicken or the egg, which came first?

  Usually, juicers remove the juice and some pulp (果肉) from fruits and/or vegetables. It takes a lot of fruit to make a container of juice. We do get all of the vitamins, minerals, beneficial plant chemicals and carbohydrates in juice out of a whole fruit. But we do not get much of the fiber, the part that aids our digestive process, fills us up, and may help protect us against heart diseases and certain cancers.

  However, you may be surprised to discover that some juices actually contain more necessary nutrients (营养). For example, apples are not a good source of vitamin C, but many types of apple juice are fortified with vitamin C.

  Juice typically has more calories than fresh fruit due to added sugar and less fiber. If calories are your primary concern, choose fresh fruit over juice and use water to quench your thirst. You can also look for low-calorie cranberry juice, typically sweetened with sugar substitute. We do not feel as filled up from juice because it does not contain any fiber. For many people, drinking a caloric beverage (饮料), such as juice, is not as satisfying as eating the same amount of calories in food. For those of us who need to increase caloric intake (such as athletes, children, or teens) juice is a GREAT choice.

    Kids love the taste of pure fruit juice, and parents love it because it is a healthy source of nutrients. But avoid junk fruit beverages which are mistaken for juice blends that contain various fruits like grape, apple and pear. These juices do not have the natural levels of vital nutrients that 100 percent pure juices like orange juice provide.

56. According to the passage, you’d better have _______ to help prevent heart disease.

    A. fruit         B. juice         C. calories       D. minerals

57. What can we learn from this passage?

    A. We can get out of fruit all the nutrients which aid our digestive process.

    B. We can hardly determine which provides more nutrients, juice or fruit.

    C. People may prefer juice to food in taking in the same amount of calories.

    D. If you want more calories, fruit might be your better choice.

58. The underlined word “blends” in Paragraph5 probably means “______”.

    A. containers B. products C. substitutes D. mixtures

59. The author writes the passage mainly _______.

    A. to remind people of negative effects of juice

    B. to call on people to drink more juice

    C. to help people learn more about fruit and juice

    D. to persuade people to avoid junk juice containing various fruits
