类型五　观点展示型 常见文体 判断标志 行文结构 主题句特点 说明文、议论文、夹叙夹议文 文中出现一个新观点，可能是一个大众的观点或某个人的观点，下文围绕该观点展开讨论 给出观点（新/旧观点）——展示观点、举例说明——评价解释 全文中心句可能为观点介绍句，通常位于第一段或第二段段首；也可能为解释评价句，通常为文章后半部分评价段落中心句 【典例】　（2024·1月浙江卷阅读C篇） 　　On September 7， 1991， the costliest hailstorm （雹暴） in Canadian history hit Calgary’s southern suburbs.As a result， since 1996 a group of insurance companies have spent about $2 million per year on the Alberta Hail Suppression Project.Airplanes seed threatening storm cells with a chemical to make small ice crystals fall as rain before they can grow into dangerous hailstones.But farmers in east-central Alberta — downwind of the hail project flights — worry that precious moisture （水分） is being stolen from their thirsty land by the cloud seeding. 　　Norman Stienwand， who farms in that area， has been addressing public meetings on this issue for years.“Basically， the provincial government is letting the insurance companies protect the Calgary-Edmonton urban area from hail，” Mr.Stienwand says， “but they’re increasing drought risk as far east as Saskatchewan.” 　　The Alberta hail project is managed by Terry Krauss， a cloud physicist who works for Weather Modification Inc.of Fargo， North Dakota.“We affect only a very small percentage of the total moisture in the air， so we cannot be causing drought，” Dr.Krauss says.“In fact， we may be helping increase the moisture downwind by creating wetter ground.” 　　One doubter about the safety of cloud seeding is Chuck Doswell， a research scientist who just retired from the University of Oklahoma.“In 1999， I personally saw significant tornadoes （龙卷风） form from a seeded storm cell in Kansas，” Dr.Doswell says.“Does cloud seeding create killer storms or reduce moisture downwind？ No one really knows， of course， but the seeding goes on.” 　　Given the degree of doubt， Mr.Stienwand suggests， “it would be wise to stop cloud seeding.” In practice， doubt has had the opposite effect.Due to the lack of scientific proof concerning their impacts， no one has succeeded in winning a lawsuit against cloud-seeding companies.Hence， private climate engineering can proceed in relative legal safety. 2 / 2 学科网（北京）股份有限公司 $
