In some parts of the world, saying something in a direct manner to a superior is regarded as rude or disrespectful. However, in other places it’s a sign of efficiency, regardless of the seniority of 43 person who you’re speaking to. When 44 (work) with colleagues, partners and clients from other parts of the world, you should spend some time researching the communication norms of their cultures. In this way, you’ll have more context information in understanding the physical and verbal communication cues 45 differ from your own. Being culturally aware means being more 46 (knowledge) about different parts of the world. Show employees you value their diversity by acknowledging and celebrating it. If your business has employees from several different countries, get them 47 (mark) their homeland on a large map in the common room. It’s 48 (probable) a great conversation-starter and a starting point for learning about other cultures. 六、阅读理解 TED is a non-profit organization devoted to Ideas Worth Spreading. It started up in 1984 as a conference bringing together people from three worlds of Technology, Entertainment and Design. Since then it has stepped into more and more fields. It includes two annual conferences — the TED Conference on the North American West Coast each spring, and the TED Global Conference in Edinburgh, the UK each summer, which bring together the world’s most excellent thinkers and doers, who are invited to give the talk of their lives in 18 minutes or less. On ted. com, we make the best talks and performances from TED and partners available to the world, for free. More than 3,000 TED talks are now available, with more to be added each week, which cover almost all topics from science to business to global issues in more than 110 languages. They really help share ideas in communities around the world. We believe in the power of ideas to change attitudes, lives and eventually, the world. So we’re building here a clearinghouse (信息交流中心) that offers free knowledge and inspiration from the world’s most inspired thinkers, and also a community of curious souls to engage with ideas and each other. Have an idea? We want to hear from you. Today, TED is best thought of as a global community. It’s a community welcoming people from every field and culture who seek a deeper understanding of the world. Want to follow TED?

In a bowl of salad, all the ingredients are mixed together. 52 Together, however, the ingredients make up a unity. All the ingredients of a salad contribute to the finished product. They may be covered with the same dressing (调味酱), but the green vegetables, tomatoes and cooked corn can all be seen for what they are. From this point of view, America is very much like a salad bowl where individual ethnic groups mix together, yet maintain their cultural uniqueness. People may work together during the day at similar jobs and in the same companies, but at night they may return to their ethnic groups where their own individual culture directs their way of life. 53 Each ethnic group has its own special customs, language, food and traditions to protect and defend. This idea of the salad bowl is referred to as cultural diversity; that is, American society is a collection of various cultures living together in harmony within one country. 54 Here, society is like one large pot of soup. All cultural aspects are mixed together, sacrificing their original identity and keeping a bit of what they were to become a new reality. The longer the soup is cooked, the better the taste and the more likely it will be for the mixture to dissolve. In this sense, America can surely be seen as a melting pot where people from all over the world come to live and work together forming one nation. There are dozens of shared symbols. 55 In such a culture, symbols like the flag and the nation’s official song serve to break down the walls which separate ethnic groups. Whether a salad bowl or a melting pot, America can be best described as a mixture of both. 56 A．Both are correct depending on one’s point of view. B．They never lose their shapes, colours or tastes. C．This is why there is so much diversity within America. D．In other words, America is a nation where there is unity in diversity. E．Thus, one needs to abandon one’s culture to be considered “American”. F．They serve to develop the various ethnic groups to create a new American culture. G．The other theory, which is also used to describe American society, is the melting pot. $分层作业 Unit 4 Period 2 Using language 目 录 A组 巩固过关 B组 能力进阶 C组 思维拔高 1、 将下列单词短语翻译为英文 4 / 8 学科网（北京）股份有限公司 【答案】 1. in favour of 2. pull down 3. face to face 4. pave the way for 5. reclaim land 6. beyond doubt 7. have a significant impact on 8. pop up 9. as if 10. turn…into… 二、根据句意及汉语提示写出单词。 【答案】 11．cast 12．minorities 13．clumsy 14．considerate 15．ignore 16．harmonious 17．joint 18．minority 19．harmonious 20．harmonious 三、用方框内所给单词的正确形式填空。 【答案】 21．amateur 22．randomly 23．harmonious 24．samples 25．submits 26．guidance 27．correspond 28．facilitate 29．surgery 30．blank 四、补全句子 【答案】 31．It is requested that anyone who wants to attend the course (should) register 32．It is known to all 33．It is/was obvious that 34．this is the first time that you have been in a foreign country，to have trouble in adapting yourself to the life here 35．occurred to 36．It is known that 37．to protect/conserve 38．It　 五、语法填空 【答案】 39．cultural 40．are shown 41．as 42．honesty 43．the 44．working 45．that/which 46．knowledgeable 47．to mark 48．probably 六、阅读理解 【答案】49．A 50．A 51．B 【分析】本文是说明文。介绍了一个致力于传播有价值的思想的非营利性组织TED，它让人们对世界有更深层次的理解，呼吁人们加入这个全球社区。 【详解】1. 细节理解题。根据第一段中的“which bring together the world's most excellent thinkers and doers, who are invited to give the talk of their lives（它把世界上最优秀的思想家和实干家聚集在一起，他们被邀请来谈论他们的生活）”可知，伟大的思想家和实干家会在TED的两场年度会议中发表演讲。故选A。 2.细节理解题。根据第一段中的“TED is a non-profit organization devoted to Ideas Worth Spreading（TED是一个致力于值得传播的想法的非营利性组织。）”可知，TED致力于传播有价值的思想。故选A。 3.推理判断题。根据文章第四段中的“It's a community welcoming people from every field and culture who seek a deeper understanding of the world（它是一个欢迎来自每个领域和文化的那些寻求对世界有更深层次了解的人的社区。）”可知，通过TED这个全球社区，人们可以对世界有更深层次的理解，由此可知，作者认为TED是有益的。故选B。 七、七选五 【答案】52．B 53．C 54．G 55．F 56．D 【导语】本文是一篇说明文。有人说美国社会就像一碗沙拉，所有的原料都混合在一起，但各种原料却没有因此失去自己的特色，即我们能看到不同种类的文化组成了现在的美国社会。另一些人则认为它是一个大熔炉，所有的文化都被混合在一起，牺牲了它们原来的身份，保留了一些它们本来的样子，成为一个新的现实。而作者认为，美国最好被描述为两者的混合体。 【详解】52．空后句“Together, however, the ingredients make up a unity.
