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(chǔ)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(gè)過(guò)程中.考生不能只依據(jù)只言片語(yǔ).或光看文章的某些段落.而應(yīng)觀察全文的結(jié)構(gòu)安排,理解文章濃墨重筆寫(xiě)的“重心 ,考慮文章的組織材料及支持性細(xì)節(jié)是服務(wù)于什么的,分析故事的發(fā)展結(jié)局都是圍繞什么內(nèi)容來(lái)表達(dá)的,最后用簡(jiǎn)明扼要的文字將文章的中心思想表達(dá)出來(lái).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.主題分析:第一段There are three separate sources of danger in supplying energy by nuclear power. 為文章的主題句.接著從三個(gè)方面論述主題:First-.Second-.Third- .段首第一句分別為各段的主題句.層次分明.結(jié)構(gòu)清晰.最后一段進(jìn)一步歸納全文大意:Dangers from nuclear power.故答案為B. 【查看更多】
