37、 of 1893,the Great Galveston Hurricane of 1900 and the Labor Day Hurricane of 1935 to name a few.The practice of using more memorable names didnt begin until 1950.It was when Atlantic tropical hurricanes received official names,although they still werent human ones.2So the 1950 season featured such

38、strangely named storms as Hurricane Dog,Hurricane Easy and Hurricane Love.3The same list of names was recycled every year,so the 19501952 seasons each featured a Hurricane Able through at least Hurricane Fox.That became confusing,so in 1953 the U.S.National Hurricane Center began using female human

39、names,which proved far more successful.Not only did it make storm identification easier,but it helped authorities and news outlets spread warnings.4The first hurricane names were often inspired by forecasters wives,but in 1979 mens names were added to the mix The World Meteorological Organization no

40、w monitors the master list of names,which alternates between male and females six lists are rotated annually in the Atlantic.So the 2015 names will be used again in 2021.5Seventy-eight Atlantic hurricane names have been retired since 1954,including 29 since 2000.A.Besides,it helped the public pay at

41、tention to them.B.These names were chosen from some familiar words.C.This naming rule,however,had an obvious weakness.D.These names of retired hurricanes are silly or unreasonable.E.But when a hurricane is bad enough,its name can be retired.F.They were usually based on the place or time of year they

42、 made landfall.G.It is also easier to use names when we have more than one storm to track.【文章大意】这是一篇说明文。文章介绍了几种给飓风命名的方式。1.【解析】F。由下一句“1893年的海岛飓风,1900年的加尔维斯顿大飓风和1935年的劳动节飓风等等。”可知,这些飓风都是根据时间或地点来命名的,承接下文,F选项“它们通常是根据它们一年中登陆的地点或时间来确定的。”切题。故选F项。2.【解析】B。由上两句“使用更容易记住的名字的做法直到1950年才开始。那是大西洋热带飓风正式命名的时候,尽管它们还不是人

43、类的名字。”和下一句“所以1950年的季节有这样命名奇怪的风暴,如飓风狗,飓风易和飓风爱。”可知,飓风狗,飓风易和飓风爱(Dog、Easy和Love很熟悉常见)都是选用熟悉的词命名的,承接上下文,B选项“这些名字是从一些熟悉的词中选出来的。”切题。故选B项。3.【解析】C。由下三句“每年都会重复使用相同的名称列表,所以1950至1952年的每一季都至少有一次“飓风能”和“飓风福克斯”。这让人很困惑,因此1953年美国国家飓风中心开始使用女性人名,这一做法被证明是成功的。它不仅使识别飓风更加容易,而且帮助当局和新闻机构传播警报。”可知,选用熟悉的词给飓风命名,会产生有“许多相同名字飓风”的弱点,

44、这让人们很困惑,这不利于识别飓风和发出警报,所以才出现了用女性人名命名的方式(有利于识别飓风和发出警报),承接下文,C选项“然而,这个命名规则有一个明显的弱点。”切题。故选C项。4.【解析】A。由上一句“它不仅使识别飓风更加容易,而且帮助当局和新闻机构传播警报。”可知,上下两句讲飓风用女性人名命名的好处,上下两句是顺承递进关系,承接上文,A选项“此外,它也有助于公众关注它们。”切题。故选A项。5.【解析】E。由下一句“自1954年以来,已有78个大西洋飓风名称被注销,其中29个是2000年以来的。”可知,承接下文,E选项“但是当飓风够糟糕的时候,它的名字可以注销。”切题;该选项中的retired对应下文的retired,同词复现。故选E项。
