UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 Lin's quick wit helped make him famous as a master of humour.Once，❼having been invited to dinner at a university，he was put on the spot when the president suddenly asked him to give a speech.Thinking on his feet，Lin started to tell a story about a cruel Roman emperor who tried to feed a man to wild animals.First came a lion.The man whispered something in the lion's ear，❽after which the lion shook its head and walked away unhappily．❾Then along came a tiger.Again，the man whispered in the tiger's ear.The tiger looked shocked UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 and hurried away.“What did you say to my animals？” said the emperor，astonished.“I told them they had to make a speech after eating me for dinner.” Lin's audience roared with laughter.With this little joke，Lin was able to make people laugh，while gently telling off the president. UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 ❼having been invited 是现在分词的完成时的被动式，主语与invite之间为被动关系，且动作invite发生在谓语动词之前。 ❽“介词(after)＋which”引导非限制性定语从句。 ❾本句为完全倒装结构。 形容词作状语，说明主语的心理状态。 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 Both Twain and Lin understood that humour isn't just about laughter，but is a way of life and a tool that can be used to illuminate the world．Lin even created an equation to explain this concept：Reality＋Dreams＋Humour＝Wisdom.Living and working with others can sometimes be complicated，and humour makes this easier.Sharing jokes and laughing together can bring individuals and even communities together.Indeed，some may argue that our need for humour is almost as great as our need for water and air.In the words of Mark Twain，“Humor is mankind's greatest blessing”． UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 that引导定语从句，修饰a tool。 动名词短语作主语。 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 ◆难词注解 ①essential adj.极其重要的，必不可少的 ②thousands of 数以千计的 ③medieval adj.中世纪的，中古时期的 ④be filled with ...充满……的 ⑤entertain v．使快乐 ⑥throw light on使……更容易理解；阐明 ⑦emotive adj.使情绪激动的 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 ⑧close to 接近，靠近 ⑨be remembered for ...因……而著名 ※be remembered as ...作为……而著名 ⑩combine ...with ... 把……和……结合起来 ⑪mischievous adj.调皮的，淘气的 ⑫classic adj.经典的 ⑬cross out划去 ⑭be known for ...因……而出名 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 ⑮remark n．言论；意见，评论 ⑯interaction n．交流 ⑰for instance＝for example例如 ⑱barber n．男理发师 ⑲shave n．刮脸，刮胡子 ⑳fellow n．男人；家伙 lecture v．讲课；演讲 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 brand of humour 某种类型的幽默 ※brand n．品牌，牌子 bilingual adj.会说两种语言的；双语的 concept n．概念，观念 in this way 用这种方式 put sb.on the spot (故意提出难以回答或尴尬的问题)使某人难堪 ※spot n．地点，处所 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 think on one's feet 思路敏捷，反应迅速 cruel adj.残忍的 feed ...to ...把……喂给…… ※ feed ...with/on ...用……喂…… whisper v．悄声说，低语 roar v．哄笑，大笑 gently adv.温和地；轻柔地 tell off 斥责，责骂 a way of life一种生活方式 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 illuminate v．照亮，照明 equation n．等式，方程式 complicated adj.难处理的；难懂的 argue that ...主张/认为…… in the words of sb.＝in one's words 用某人的话来说 blessing n．幸事，幸运，福气 UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 Ⅱ.文本理解 ►主旨大意 This passage is mainly about Mark Twain and Lin Yutang's attitude towards ______． humour UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 ►文章架构 essential funny witty brand wit life illuminate UNIT 1　SCIENCE AND SCIENTISTS 高中英语　选择性必修　第二册　R 返回导航 ►细节探究 1．According to Paragraph 2，what is Mark Twain's special writing style？(　　) A．Easy.
