问答题5. Zoning laws regulate the development of a region's land and are specifically focused on what structures can be built in various places. For the most part, zoning laws are designed to prevent incompatible structures, such as factories and schools, from being built alongside one another. Thus urban areas have many different zones. Among them are residential zones for housing and schools, business zones for offices, stores, and shopping malls, green zones for parks and recreation, and industrial zones for factories and other manufacturing centers. The zones provide benefits for their communities in a variety of ways. One is that they preserve the property value of private land. For instance, homeowners prefer to live in regions which only have houses and schools and have small numbers of stores and office buildings. A person's home would lose much of its value if a large factory were suddenly erected across the street from it. The homeowner would consequently have trouble selling the house, which is something zoning laws prevent from happening. Zoning laws further help maintain the integrity and safety of neighborhoods by preventing certain types of entertainment establishments from being built in residential zones. Most cities, as an example, do not permit nightclubs and bars to be opened near schools and housing areas. Zoning laws additionally preserve green lands in urban regions. Therefore, parks and recreation zones are safe from being developed for purposes that would destroy their natural beauty. A third benefit of zoning laws is that they maintain the historical integrity of communities which are in danger of being developed for new, yet incompatible, purposes. In that way, they can enable neighborhoods with historical structures of significance to avoid being transformed into industrial or entertainment districts that can bring ruination to the older buildings.

问答题5. The mountain yellow-legged frog was once common in the Sierra Nevada Mountains in Southern California, yet its numbers are in such steep decline today that it has been placed on the endangered species list. The reason for its decline has been attributed to three different factors, all of which have combined to devastate the mountain yellow-legged frog population. The first problem has to do with the introduction of trout into the lakes and streams in the Sierra Nevada Mountains in the late nineteenth century, which disturbed the balance in the ecosystem there. Trout were a nonnative species in that region, and they quickly grew in numbers, primarily by feeding on mountain yellow-legged frog tadpoles and juveniles. Prior to the introduction of the trout, the frogs had no aquatic predators, so it was not instinctive for them to flee from the trout. A second problem involves the various pesticides that have been utilized to kill pests both on trees and farmland for many years. During periods of rain or snow, the pesticides combine with the water and enter the local water system. They have therefore contaminated the water and wound up killing large numbers of frogs. Examinations of dead frogs have shown that many of them contained excessive amounts of pesticides in their bodies when they died. A third problem that has affected the environment in which the frog lives is the growth of a deadly fungus in the region. This fungus attacks adult frogs and destroys the keratin in their bodies. Keratin comprises a signification portion of the skeletons and teeth of frogs, so their entire bodies become weakened and result in the frogs dying. Some frogs die as quickly as two weeks after becoming infected with the fungus. Directions You have 20 minutes to plan and write your response.
