课件40张PPT。【美文阅读】 US volunteer travels across country to help people in need 狄更斯曾说“世界上能为别人减轻负担的都不是庸庸碌碌之徒”。Drew Johnson用自己的行动向我们展现了一个普通的网页设计者助人为乐的伟大人格。He began his journey last October and is documenting his experiences on a blog.“I wanted to invite people along with me，and I think some of the best ways to do that is through pictures，video and writing.” When Nashville，Tennessee，was destroyed by flooding this year，he helped people remove ruins from their homes.He also lent a hand to refugees，including people from Burundi in East Africa. Today he is delivering free meals to the elderly in Maryland through a program called Meals on Wheels.Peggy Toole of Meals on Wheels says Johnson is a wonderful surprise.“Johnson does the dirty jobs some volunteers don't want to do.I wish there are more people like him putting a spotlight on how important it is to volunteer，to just help someone and to put yourself in somebody else's position.” “You can use your talents，your abilities in so many different areas out there to actually help people and make this world a better place，” Johnson said.【诱思导学】 1．What does the underlined word “it” in Paragraph 1 refer to ? _____ _____ 2．Why does Drew Johnson document his experiences on a blog? _____ _____【答案】 1.Johnson's intention to make a road trip to help people in need. 2.He wants to use this method to encourage more people to become volunteers.●教学目标 初步掌握本课文中的词汇，浅层次理解课文，了解相关的背景知识。 本课时主要是通过学生对学案所给出的内容的学习，了解本课文中所出现的词汇，初步了解课文以及相关的背景知识，对下一堂课对课文的全面理解起到一个铺垫作用。教师用书独具演示●教学地位 本单元是新高二的第一课，上好这一课至关重要，会给学生留下非常深刻的印象。高二是学生高中时期的重要阶段，而且此时的高中生正是富有理想和朝气的年龄，引导他们向伟人学习，树立远大理想，为报效祖国而努力学习。通过本节的教学，让学生了解伟人的生活和事迹，帮助学生培养探索、钻研、无畏的科学精神。俗话说“万事开头难”。那么就通过老师的智慧，开个好头吧。●新课导入建议 通过介绍科学家钱学森的事迹导入新课。让学生了解科学家的生活和工作 。 大家可能都知道一些钱学森的业绩和故事，让同学们自由发言，讲述最令他们感动和最值得他们学习的地方。最后老师做出总结。演示结束 Ⅰ.篇章结构 阅读P2的Reading部分，完成下列表格(每空不超过3个单词)【答案】 1.cause 2.Make a decision 3.Collect 4.Collect results 5.died 6.Analyse 7.Find supporting evidence 8.conclusion 9.polluted 10.blameⅡ.语篇理解 阅读P2的Reading部分，从每题所给的3个选项中选择最佳答案 1．What does the passage mainly talk about?
