    抓住文章段落大意.概括中心思想寻找整篇文章的中心思想是建立在寻找具体段落中心的基础上的.各段落中心句的整体归纳便是文章的中心思想.在这个过程中.考生不能只依据只言片语.或光看文章的某些段落.而应观察全文的结构安排,理解文章浓墨重笔写的“重心 ,考虑文章的组织材料及支持性细节是服务于什么的,分析故事的发展结局都是围绕什么内容来表达的,最后用简明扼要的文字将文章的中心思想表达出来.如:There are three separate sources of danger in supplying energy by nuclear power. First, the radioactive material must travel from its place of production to the power station. Although the power stations themselves are strongly built, the containers used for the transport of the materials are not. Normally, only two methods of transport are in use, namely road or rail. Unfortunately, both of these may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.Second, there is the problem of waste. All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these wastes nonradioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the ground, or dropped into deserted mines, or sunk in the sea. However, these methods do not solve the problem, since an earthquake could easily break the containers.Third, there may occur the danger of a leak or an explosion at the power station. As with the other two dangers, this is not very likely, so it does not provide a serious objection to the nuclear program. However, it can happen.Separately, these three types of dangers are not a great cause for worry. Taken together, though, the probability of disaster is extremely high.Q: What is the passage about? A. Uses of nuclear power. B. Dangers from nuclear power.C. Public anger at nuclear power. D. Accidents caused by nuclear power.主题分析:第一段There are three separate sources of danger in supplying energy by nuclear power. 为文章的主题句.接着从三个方面论述主题:First-.Second-.Third- .段首第一句分别为各段的主题句.层次分明.结构清晰.最后一段进一步归纳全文大意:Dangers from nuclear power.故答案为B. 【查看更多】
