Franklin’s Experiment: How much is true? para. 1 Benjamin Franklin's famous experiment with lightning has introduced generations of children to science. However, new research suggests that the story may be fiction instead of fact. suggest “暗示、表明 ”(infer/indicate/imply/suggest推理判断题) suggest用法小结 1 表“建议” I suggested putting off the sports meeting. She suggested that the class meeting (should) not be held on Saturday. 2 表“提出” He suggested a different plan to his boss. 3 表“暗示、表明 ” The decision suggested that he might bringhis family. 4 用于主语从句It is suggested that... 后面表示具体建议的表语从句、同位语从句都应 用should+动词原形，should可以省略。 instead of与instead 易混词(组) 用法 例句 instead of 介词短语，后面一般接名词(短语)、代词、动名词(短语)作宾语 Instead of being annoyed, he seemed quite pleased. instead 副词，单独使用 Mr Wang is ill.

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 to it. A metal key was attached to the string. A flash of lightning hit the kite, and electricity was conducted through the string to the key. Franklin then touched the key with his finger and got an electric shock. This, he said, proved that lightning was a form of electricity. fly-flew-flown tie … to … 把……系在……上 tie n. 领带（tie a tie 打领带） 1 The weather tied him to the house. 2 Tie the horse to the tree.

More than one generation of schoolchildren has been amazed by his bravery and his scientific approach to looking for the truth. Franklin, along with many other scientists, has inspired us and taught us that scientific experiments are important in order to establish the truth and to contribute towards later scientific discoveries and inventions. ① More than one generation of schoolchildren has been amazed by his bravery and his scientific approach to looking for the truth. ② ..., more than one scientist has questioned what really happened. ③ In fact, more than one account suggests that while Newton was certainly inspired by a falling apple, ... “more than one+单数名词”意为“不止一个”,作主语时，谓语动词的单复数要从形式一致角度考虑，通常用单数。 along with 使用的是就远原则， 谓语动词与前面 主语一致。表示“与……一道，与……一起，共同， 连同，和；作伴；随着 ” in addition to together with rather than including along with besides but except as well as para. 4 However, neither the story nor the details of the experiment are entirely true. Although it has been proved that Franklin’ s experiment took place/happened(vi), more than one scientist has questioned what really happened. 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 from the electric shock. die from/die of However, neither the story nor the details of the experiment are entirely true. neither ... nor... 既不……也不…… 当neither...nor...连接两个主语时，谓语动词单复数应遵循“就近原则”。 neither...or... not only...but also... there be... para. 5 Scientists often question accepted ideas 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 with his theory of gravity. In fact, more than one account suggests that while Newton was certainly inspired by a falling apple, there is no proof that it hit him on the head. fall-fell-fallen give sb. an account of 向某人描述…… on account of 由于…… take account of =take …into account 考虑到，顾及 open/close an account 开立/结清账户 e.g. I hope my teacher will take account of the fact that I was ill just before the exams when she marks my paper.

People have been more inspired by Franklin’ s spirit of scientific exploration than by the facts themselves. But in science, facts should be proved by experiments and research, and we should not always believe everything (that) we read or hear — even if it is a great story. $$
