我们以剑七Test 1,Passage 2为例,在这篇文章中,E段首句“At the outset of the new millennium,however,the way resource planners think about water is beginning to change。”Change一词对应i选项中的revision,都是表示改变,剩下的选项没有相关的意思,因此可以通过首句确定段落大意为i.Scientists'call for a revision of policy.F段首句”Fortunately–and unexpectedly-the demand for water is not rising as rapidly as some predicted。”unecpectedly对应选项ix中的surprising,not rising对应downward trend,很容易看出答案为ix.A surprising downward trend in demand for water。G段同理,首句“What explains this remarkable turn of events?”即此段要解释这样一种现象的原因,很容易看到ii中的同意转换词explanation。而D段首句“The consequence of our water policies extend beyond jeopardizing human health。”很明显是在总结上一段的段落大意,即承上启下,这时我们可以通过这句来验证上一个段落的大意,并从剩下的内容中去寻找段落大意。B段虽然给出了答案,但我们还是可以来自己分析一下,B段开头给出的都是新时期我们面临的种种问题,而后一句“Nearly one fifth of all the electricity generated worldwide is produced by turbines spun by the power of falling water。”为我们指出了这些问题是被如何解决的,即对应Headings中的iii.How a global challenge was met。
因此以后在做list of headings类题目是,一定要仔细看段落的首句,二句以及末句,争取通过这三句话弄清段落大意。
