(2024浙江1月,C)
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.
1.What does the project aim to do
A.Conserve moisture in the soil. B.Prevent the formation of hailstones.
C.Forecast disastrous hailstorms. D.Investigate chemical use in farming.
2.Who are opposed to the project
A.Farmers in east-central Alberta. B.Managers of insurance companies.
C.Provincial government officials. D.Residents of Calgary and Edmonton.
3.Why does Dr. Doswell mention the tornadoes he saw in 1999
A.To compare different kinds of seeding methods.
B.To illustrate the development of big hailstorms.
C.To indicate a possible danger of cloud seeding.
D.To show the link between storms and moisture.
4.What can we infer from the last paragraph
A.Scientific studies have proved Stienwand right.
B.Private climate engineering is illegal in Canada.
C.The doubt about cloud seeding has disappeared.
D.Cloud-seeding companies will continue to exist.

◎语篇解读 本文是一篇说明文,主题语境是人与自然,主题语境内容是自然灾害与防范。文章主要介绍了加拿大艾伯塔省实施防雹项目,对于该项目人们态度不一。
1.B 本题为细节理解题。本题题干意为:这个项目的目标是什么 A.保护土壤里的水分;B.防止冰雹的形成;C.预测灾难性的雹暴;D.调查农业中的化学品使用情况。根据第一段中“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.(因此,自1996年以来,一组保险公司每年在艾伯塔省防雹项目上花费约200万美元。飞机在阴沉沉的风暴云泡中播撒一种化学物质,使小冰晶在变成危险的冰雹之前像雨一样落下。)”可知,这个项目的目标是防止冰雹的形成。故选B项。
2.A 本题为细节理解题。本题题干意为:谁反对这个项目 A.艾伯塔省中东部的农民;B.保险公司的经理;C.省政府官员;D.卡尔加里和埃德蒙顿的居民。根据第一段中“But farmers in east-central Alberta—downwind of the hail project flights—worry that precious moisture is being stolen from their thirsty land by the cloud seeding.(但是,在艾伯塔省中东部——冰雹项目飞行的顺风处——的农民们担心,宝贵的水分正被播云从他们干旱的土地上偷走。)”可知,艾伯塔省中东部的农民反对这个项目。故选A项。
3.C 本题为推理判断题。本题题干意为:为什么Doswell博士提到他在1999年看到的龙卷风 A.比较不同种类的播种方法;B.说明大雹暴的发展;C.表示播云可能带来的危险;D.显示暴风雨和水分之间的联系。根据倒数第二段“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 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.’(Chuck Doswell是一位刚刚从俄克拉何马大学退休的研究科学家,他对播云的安全性持怀疑态度。‘1999年,我在堪萨斯州目睹了由播种过的风暴云泡形成的重大龙卷风。’Doswell博士说。‘播云会制造致命风暴还是减少顺风处的水分 当然,没有人真正知道,但是播云还在继续。’)”可推知,Doswell博士提到他在1999年看到的龙卷风是为了提示播云可能带来的危险。故选C项。
4.D 本题为推理判断题。本题题干意为:从最后一段我们能推断出什么 A.科学研究证明Stienwand是对的;B.私人气候工程在加拿大是非法的;C.关于播云的疑虑已经消失;D.播云公司将继续存在。根据最后一段中“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.(由于缺乏有关其影响的科学证据,没有人成功地赢得对播云公司的诉讼。因此,私人气候工程可以在相对合法的安全条件下继续进行。)”可推知,从最后一段我们能推断出播云公司将继续存在。故选D项。
长难句
原句 But farmers in east-central Alberta—downwind of the hail project flights—worry that precious moisture is being stolen from their thirsty land by the cloud seeding.
分析 本句是一个主从复合句。本句的主干是farmers worry that...。that...cloud seeding是宾语从句。两个破折号之间的部分作插入语,解释说明east-central Alberta。
译文 但是,在艾伯塔省中东部——冰雹项目飞行的顺风处——的农民们担心,播云正在从他们干旱的土地上偷走宝贵的水分。
