 In modern hospitals, the most popular treatment for bacterial infection is antibiotics. While these medicines are generally highly effective in (41) the infection, one problem is that over a period of time bacteria begin to mutate—change their structure—in order to resist the antibiotics. (42) , as the human population consumes more antibiotics, the infection-producing (43) become stronger and more resistant to the drugs. Another reason for the increased consumption of antibiotics is that doctors often prescribe them to patients too (44) . Both doctors and patients prefer treatment providing fast relief, rather than (45) the body to battle the infection by itself. (46) unnecessary prescriptions are not the only source of antibiotics. They have been increasingly (47) on farms, where chickens and pigs are frequently fed antibiotics to combat disease.

 In any group of elderly people, it is common to see some women who are unable to stand completely upright. Their backs and heads are bent forward slightly, as if they were carrying a heavy load. This is usually a sign of a bone problem that has developed over a number of years, a problem called osteoporosis. Osteoporosis literally means porous bones—bones that are filled with tiny holes. Our bones are in a constant state of change, continuously broken down and rebuilt through the body’s chemical processes. Two kinds of cells are important in these processes: osteoclasts and osteoblasts. Osteoclasts renew the old bone by dissolving or reabsorbing it; this leaves an empty space. Osteoblasts then fill this empty space with new bone. When the rate of bone renewal doesn’t equal the rate of breakdown, bone loss results. When the bone loss becomes advanced, it is called osteoporosis. The bones don’t actually change shape with osteoporosis; rather, they become porous, and therefore are more likely to break. Often the first sign of osteoporosis is a bone fracture following a minor fall or accident.

 For thousands of years, Chinese artists have used a material called lacquer to prevent the surfaces of objects made of wood or other materials from being damaged. Many beautiful lacquer pieces can be found today in collections of Chinese art. The process of producing a lacquer piece, however, is both difficult and long. To begin with, the original object must be made, perhaps a wooden bowl or vase with a design carved in its surface. Meanwhile, farmers collect raw, liquid lacquer from lacquer trees, each of which can produce only a small amount. After enough lacquer has been collected, a lacquer artist must then clean it by passing it through cloth and also beat it in order to remove excess water. The original color of the lacquer is not attractive so the artist next adds some other material to change the color to red or black. Now, the artist can put the first of many layers of lacquer onto the surface of the object. After the first layer is dry, he must polish it and then apply the next layer. When the last layer has been applied, the object will not only be beautiful, but also safeguarded against damage.

One of the largest youth organizations in the world is the 4-H, an organization of clubs for young people between 9 and 19. The main purpose of 4-H is to provide young people with the practical skills and understanding they will need to become useful members of their communities. The four H’s stand for head, heart, hands, and health. When 4-H clubs first began in America in the early 1900s, members were mostly young people from rural areas. The focus was on farm projects, such as raising pigs and growing and canning food. Today over 75% of the club members come from towns, cities, and suburbs, and hundreds of projects exist, each adapted to its geographical area. While rural districts abound in conservation, forestry, and farm management projects, projects in urban areas often involve nutrition, health, automotive care, and money management. The 4-H program in America is a joint service of the U.S. Department of Agriculture, state universities, and county governments. Additional funding is provided by business firms and private organizations. Members of the clubs are guided by volunteer adult leaders and their teenage assistants. In the clubs, 4-H’ers learn about and work on solving serious problems that face their communities, issues like environmental protection and community safety. In addition to the 4-H clubs in the U.S. states and territories, more than eighty countries, including Taiwan, have adapted the 4-H idea to fit their own needs. In the less developed countries, many clubs offer courses in proper nutrition and in new farming technology.
