抓住文章段落大意.概括中心思想尋找整篇文章的中心思想是建立在尋找具體段落中心的基礎上的.各段落中心句的整體歸納便是文章的中心思想.在這個過程中.考生不能只依據只言片語.或光看文章的某些段落.而應觀察全文的結構安排,理解文章濃墨重筆寫的“重心 ,考慮文章的組織材料及支持性細節是服務于什么的,分析故事的發展結局都是圍繞什么內容來表達的,最后用簡明扼要的文字將文章的中心思想表達出來.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.
