However，new research suggests that the story may be fiction④ instead of fact　[1]． [1]此处是that引导宾语从句。suggest 在此处意为“暗示，表明”，从句中需使用陈述语气。 2．The well­known story is that the American Founding Father and scientist flew a kite⑤during a storm in 1752　[2]．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 kit with a piece of string tied to⑥it　[3]．A metal⑦ key was attached⑧to the string.A flash of lightning hit the kite，and electricity was conducted ⑨through the string to the key. Franklin then touched the key with his finger and got an electric shock⑩.This，he said，proved that lightning was a form of electricity. [2]此处是that引导表语从句。 [3]此处是“with＋宾语＋宾语补助语”的结构，a piece of string与tied to之间为被动关系。 3．For many years，schools have taught the story of Franklin's lightning experiment. More than one generation of school children has　[4]been amazed by⑪ his bravery⑫ and his scientific⑬ approach⑭ to looking for the truth.Franklin，along with ⑮ many other scientists，has inspired us and taught us that scientific experiments are important in order to establish⑯ the truth and to contribute⑰ towards later scientific discoveries and inventions. [4]此处是“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。 4.However，neither the story nor the details of the experiment are entirely⑱ true　[5]．Although it has been proved that Franklin's experiment took place⑲， more than one scientist has questioned what really happened　[6]．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 from⑳ the electric shock　[7]． [5]neither...nor...意为“既不……也不……”，连接并列主语时，谓语动词应遵循就近一致原则。 [6]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。 [7]此处是虚拟条件句，表示与过去事实相反的情况。 5．Scientists often question accepted ideaseq \o(○,\s\up3(21)) because they want to establish the facts.Some have even questioned the story about the apple that fell on Newton's head and led him to come up witheq \o(○,\s\up3(22)) his theory of gravityeq \o(○,\s\up3(23)).In fact，more than one accounteq \o(○,\s\up3(24)) suggests that while Newton was certainly inspired by a falling apple，there is no proofeq \o(○,\s\up3(25)) that it hit him on the head　[8]. [8]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。 6．Admittedlyeq \o(○,\s\up3(26))，fiction is often more interesting than the truth. People have been more inspired by Franklin's spirit of scientific explorationeq \o(○,\s\up3(27)) 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　[9]． [9]此处even if引导让步状语从句。 参考译文 富兰克林的实验： 有多少是真的？ 1．本杰明·富兰克林有关闪电的著名实验使几代儿童初次了解了科学。然而，新的研究表明，这一故事可能只是杜撰，而非事实。 2．这位美国制宪元勋兼科学家在1752年的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还是其他东西产生的。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。一道闪电击中风筝，电通过绳子传导至钥匙上。随后富兰克林用手指触摸钥匙，遭到了电击。他说，这证明闪电是电的一种形式。 3．很多年以来，学校都会讲授富兰克林的闪电实验。几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，并教会我们无论是为了证实真相，还是为了促成日后的科学发现和发明，科学实验都很重要。 4.然而，这个故事以及实验的细节都不完全真实。尽管有人证明富兰克林进行了这一实验，但不止一位科学家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。 5．科学家经常会质疑已为人接受的观点，因为他们想要查明真相。甚至有人曾质疑过苹果掉在牛顿头上而促使他提出了重力理论的故事。事实上，不少记述表明牛顿确实受到了掉落苹果的启发，但没有证据显示苹果砸在了他的头上。 6．不可否认的是，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——哪怕是个了不起的故事。 Ⅰ.Reading for main idea 　What is the text mainly about?
