答案

参考答案:D

解析:基于区域的景观过程和格局的关系,通过景观过程的分析和模拟,来判别对这些过程的健康与安全具有关键意义的景观格局。区域生态安全格局途径把景观过程作为通过克服空间阻力来实现景观控制和覆盖的过程。要有效地实现控制和覆盖,必须占领具有战略意义的关键性的景观元素、空间位置和联系。这种关键性元素、战略位置和联系所形成的格局就是区域生态安全格局,他们对维护和控制生态过程或其他水平过程具有异常重要的意义。根据景观过程之动态和趋势,判别和设计区域生态安全格局。不同安全水平上的安全格局为城乡建设决策者的景观改变提供了辩护策略。这些区域生态安全格局构成区域和城市的生态基础设施或潜在的生态基础设施。

In most languages, a greeting is usually followed by "small talk". Small talk means the little things we talk about at the start of a conversation. In English-speaking countries people often make small talk about the weather: "Nice day, isn't it?" "Terrible weather, isn't it?" But there is something special about small talk. It must be about something which both people have the same opinion about. The purpose of small. talk is to let both people agree on something. This makes meeting people easier and more comfortable. People usually agree about the weather, so it is a safe topic for small talk. But people often disagree about religion or politics so these are not suitable topics for small talk in English. The topics for small talk also depend on where the conversation is taking place. At football matches, people make small talk about the game they are watching: "Great game, isn't it?" At bus-stops, people may comment about the transport system: "The bus service is terrible, isn't it?"

Greetings and small talk are an important part of conversation in any language. The way people greet each other and the things they talk about, however, may be different from one language to another. This shows that there is much more to learn when we learn a language than just the vocabulary and the grammar of the language. We also have to learn the social behavior of the people who speak it.
