重大版选修6 Unit 2 Troublesome Travelers reading（共35张PPT）

课件35张PPT。Troublesome TravelersWords reviewRead the explanation and speak out the word it explains.汉语是我们的母语，我们从学英语开始，就是用汉语来解释和记忆英语的。变“用汉语解释和记忆英语”为“用英语解释和记忆英语”。避免了将英语转换为另一种语言——汉语所带来的不便和时间耗费。不但提高了效率，而且久而久之，有可能在头脑中建立起两种思维系统，即在在汉语思维之外，还可以逐步建立起独立的英语思维系统。用英语解释和记忆英语，本身就是在学习和运用英语，对提高英语语感和英语的阅读理解能力和综合运用能力很有好处。是一举多得的好方法。真正做到了用英语品味英语，越品越有味；用英语理解英语，理解更准确。鉴于本环节初次尝试此种设置，可能有些学生对英语解释不能完全理解，为降低难度，英文解释后面可进一步演示中文解释，学生可再通过中文解释回顾早读课中已预习过的单词，进一步加深记忆。words reviewto keep something as it is, especially in order to prevent it from decaying or being damaged or destroyed; to conserve vt.保护，维护preservea result of a particular action or situation, often one which is bad or not convenient n.结果consequencecompletely, very much adv.彻底地，完全地thoroughlywhen you look at something carefully, or an official visit to a building or organization to check that everything is correct and legal vt.检查；视察inspection(of a person) not guilty of a particular crime, or having no knowledge of the unpleasant and evil things in life, or (of a thing) not intended to harm anyone adj.无罪的innocentIf people migrate, they travel in large numbers to a new place to live temporarily vi.移居国外migrateblame…on…
