generations of children to science.However，new research suggests that the story may be fiction④ instead of fact【2】． 【1】[标题赏析]本文标题以疑问句的形式呈现，紧扣文章内容，对富兰克林著名的风筝实验的真实性进行怀疑和求证，简明扼要地说明了本文要讨论的问题，点出了文章主旨；同时设置悬念，引起读者的阅读兴趣。 【2】句中that引导宾语从句，suggest在此意为“表明”，故从句使用陈述语气。 The well­known story is that the American Founding Father and scientist flew a kite during a storm in 1752【3】．At that time，there was much interest in electricity.People wanted to know if lightning was really produced by electricity or something else.Franklin was one of them.He raised the kite with a piece of string tied to⑤ it【4】．A metal⑥ key was attached⑦to the string.A flash of lightning hit the kite，and electricity was conducted⑧through the string to the key.Franklin then touched the key with his finger and got an electric shock⑨.This，he said，proved that lightning was a form of electricity. 【3】此处是that引导的表语从句。 【4】此处是“with＋宾语＋宾补”结构；因a piece of string与tie之间是逻辑上的动宾关系，所以用过去分词作宾补。 For many years，schools have taught the story of Franklin's lightning experiment.More than one generation of schoolchildren has【5】been amazed by his bravery⑩ and his scientific approach⑪ to looking for the truth.Franklin，along with⑫many other scientists，has inspired us and taught us that scientific experiments are important in order to establish the truth⑬ and to contribute⑭towards later scientific discoveries and inventions. 【5】此处属于“more than one＋可数名词单数”结构，意为“不止一个……”，其作主语时，谓语动词用单数形式。 [思考]课文中共出现了三处“more than one＋可数名词单数”作主语的句子，请找出其余两处并体会该语法特征。 However，neither the story nor the details of the experiment are entirely⑮ true【6】．Although it has been proved that Franklin's experiment took place⑯，more than one scientist has questioned what really happened.【7】The detail about the string and the key is true.But scientists all agree that if Franklin had actually touched the key，he would certainly have died from⑰ the electric shock【8】． 【6】“neither...nor...”意为“既不……，也不……”，连接并列主语时，谓语动词的人称和数遵循“就近一致”原则。 【7】此处Although引导让步状语从句；what really happened是what引导的宾语从句，what在从句中作主语。 【8】此处是虚拟条件句，表示与过去事实相反的情况。 Scientists often question accepted ideas⑱because they want to establish the facts.Some have even questioned the story about the apple that fell on Newton's head andled him to come up with⑲his theory of gravity⑳.In fact，more than one accounteq \o(○,\s\up8(21))suggests that while Newton was certainly inspired by a falling apple，there is no proofeq \o(○,\s\up8(22)) that it hit him on the head【9】． 【9】此处“that while...head”为that引导的宾语从句，该从句中又包含一个主从复合句。其中while引导让步状语从句；that it hit him on the head为同位语从句，解释说明proof的内容。 Admittedlyeq \o(○,\s\up8(23))，fiction is often more interesting than the truth.People have been more inspired by Franklin's spirit of scientific explorationeq \o(○,\s\up8(24))than by the facts themselves.But in science，facts should be proved by experiments and research，and we should not always believe everything we read or hear－even if it is a great story【10】． 【10】even if在此引导让步状语从句。 名师圈点 ①experiment/Ik'sperImənt/n.[C，U](科学)实验vi.做实验 ②lightning/'laItnIŋ/n.[U]闪电 a flash of lightning一道闪电 ③introduce vt.熟词生义 使初次了解，使尝试 introduce sb to sth使某人初次了解某事/物 ④fiction/'fIkʃ(ə)n/n.[C，U]虚构的事，想象的事；[U]小说 ⑤tie...to...将……系在……上 ⑥metal/'metl/n.[C，U]金属 ⑦attach/'ətætʃ/vt.系，绑；贴 ⑧conduct/kən'dʌkt/vt.传导(热、电等)

本杰明·富兰克林有关闪电的著名实验已引领一代又一代的儿童迈入科学世界。然而，新的研究表明，这一故事可能只是杜撰的，而非事实。 这位美国开国元勋兼科学家在1752年一场暴风雨中放风筝的故事可谓家喻户晓。在那时，人们对于电兴趣浓厚，想要知道闪电是否真的由电产生，还是另有源头。富兰克林就是其中之一。他在风筝上绑了一根绳子，然后将其放高。绳子上还绑着一把金属钥匙。一道闪电击中了风筝，电流通过绳子传导至钥匙上。随后富兰克林用手指触摸钥匙，感受到了电击。他说，这一实验证明闪电是电的一种形式。 很多年以来，学校都会讲授富兰克林的闪电实验的故事。数代学生都曾为他的勇敢和探索真理的科学方式而惊叹不已。富兰克林与许多其他科学家一样激励了我们，并教导我们科学实验对于推定真理和推动科学发现及发明而言都至关重要。 然而，不管是故事本身还是实验细节都并非完全属实。尽管已证实富兰克林进行了这一实验，不少科学家还是对真实的情形提出过质疑。绳子和钥匙相关的细节是真的，不过科学家们一致认为，如果富兰克林真的触摸了钥匙，他肯定会因触电而亡。 科学家经常会质疑已被人接受的观点，因为他们想要查明真相。一些科学家甚至曾质疑过苹果掉在牛顿头上而促使他提出了万有引力定律的故事。事实上，不少资料表明，虽然牛顿确实受到了掉落苹果的启发，但没有证据表明这个苹果砸在了他的头上。 诚然，虚构的故事往往比事实更有吸引力。人们从富兰克林的科学探索精神受到的启发远胜于事实本身。不过，在科学领域，事实应通过实验和研究证明，我们不能轻信读到或听到的任何事情——哪怕它是一个精彩的故事。 Ⅰ.重点单词 ●核心单词 1．　draft v. 起草，草拟 2．　experiment n.
