现代大学英语精读3第三版教学课件B3U51. 课程介绍本篇教学课件是现代大学英语精读3第三版教材中的第五课单元（Unit 5）的教学课件。
本课旨在帮助学生进一步掌握有关文化差异和交际技巧的知识，并提高他们的英语阅读和理解能力。
本课的主题是文化差异与语言交际，通过讲解和讨论相关话题，培养学生的跨文化交际意识和能力。
1.1 教学目标•了解不同文化背景下的交际差异•掌握谈论文化差异的词汇和表达方式•提高阅读技巧和理解能力•培养跨文化交际意识和能力1.2 教学内容•课文导入•词汇讲解•阅读理解•文化差异与交际技巧讨论•练习与巩固2. 课堂内容2.1 课文导入首先，我们将通过一个小故事来引入本节课的主题。
请看下面这个故事：Mr. Smith, an American businessman, went to China on a business trip. On the first day of his visit, he had a meeting withhis Chinese partners. During the meeting, Mr. Smith crossed his legs, showing the sole of his shoe to the Chinese partners. This action caused great offense to the Chinese partners, as showing the sole of one’s shoe is considered impolite in Chinese culture.通过这个故事，我们可以看到不同文化背景下的交际差异。
在中国文化中，露出鞋底是不礼貌的，而在美国文化中可能没有这样的问题。
这个例子揭示了文化差异对交际的影响。
2.2 词汇讲解在本节课中，我们将学习一些与文化差异和交际技巧相关的词汇和表达方式。
请看下面的表格：单词词性解释cultural adj.文化的difference n.差异、区别communication n.交流、沟通etiquette n.礼仪offend v.冒犯、得罪gesture n.手势misinterpret v.误解appropriate adj.适当的foreign adj.外国的respect n./v.尊重behavior n.行为custom n.习俗tradition n.传统adapt v.适应、调整misunderstand v.误解social adj.社交的interaction n.互动diplomatic adj.外交的sensitive adj.敏感的cultural adj.文化的language n.语言、表达方式custom n.风俗、习惯2.3 阅读理解现在，让我们阅读一篇与文化差异和交际技巧相关的短文，并回答以下问题：Cultural Differences in CommunicationWhen people from different cultures meet and communicate, there are often challenges and misunderstandings due to cultural differences. For example, in some cultures, it is common to maintain direct eye contact during a conversation as a sign of respect and attention, while in other cultures, avoiding eye contact is seen as a sign of respect. Thus, what is considered polite in one culture may be considered impolite in another.Another important aspect of cross-cultural communication is body language and gestures. Different cultures have different meanings behind certain gestures. For example, the。

(2)reflective通过用词来折射 ◎The nation that sent more than 9 million people to college on the GI Bill is now pricing a college education out of reach of its young people. Instead, we have spawned(造就)an unskilled, poorly educated class that requires extensive social support and contributes little to the economy.
To a kid, a savings account is just a black hole that swallows birthday checks.
Dragging Space and Time The results of two studies announced in early November 1997 provide unprecedented support for “frame-dragging,” a concept predicted by physicist Albert Einstein's general theory of relativity. Frame-dragging describes how massive objects actually distort space and time around themselves as they rotate. One of the studies examined frame-dragging around black holes, an example of which is shown here in an artist's conception.

Quotes from Rachel Carson
It is the public that is being asked to assume the risks that the insect controllers calculate. The public must decide whether it wishes to continue on the present road, and it can do so only when in full possession of the facts. We still talk in terms of conquest. We still haven't become mature enough to think of ourselves as only a tiny part of a vast and incredible universe. Man's attitude toward nature is today critically important simply because we have now acquired a fateful power to alter and destroy nature.

SENTENCES
Paragraph1: The town lay in the midst of prosperous farms, where, in spring, white clouds of bloom drifted above the green fields. 白色鲜花像云彩般漂浮在绿色的田野
Influence of Silent Spring
After the book was published, it attracted public attention.
During this period, the United States revised a series of laws to protect the environment, and established environmental protection agency.
Background of Silent Spring
In the 1950s,after World War II, American economy grew rapidly, with the development of industrialization and urbanization. At the same time, environmental pollution is becoming more and more serous.
DDT pesticide is widely used in agriculture. It does great harm to the environment and human beings
现代大学英语第三册第五课(Slient Spring)
Cultural Notes
The origin of the article
This fable was taken from Carson’s prophetic book: Silent Spring (1962), which was an expose of the long-term effects of pesticides upon our environment. She argued that we had entered the age of chemicals willy-nilly (不管愿 不愿意) without considering the totality of nature. Processes within nature were working to undo the very things we hoped to achieve using pesticides, thereby causing large-scale imbalances. To be precise, she urged us to better understand nature and to use its processes to our advantage without the use of pesticides.
Fortunately the American government responded to her revelations. John F.Kennedy in the White House, Stuart Udall at Interior, Hubert Humphrey in the Senate, and William O.Douglas in the Supreme Court-- proposed, implemented, and defended legislation that regulated industry, set standards, saved lives and changed the course of history. As Rev. John E.Gibbons pointed out, this book is the one with the greatest impact in the last century.
