24、lationB.或许正是我们的男女社会观念加深了女人比男人话多这一模式化印象，甚至导致这些不同沟通方式的出现。如果一个女人真的在别人说话时插嘴，她或许会被认为是话多，或许会为此受到批评，因为我们的文化-还有其他许多文化-如此教导女性：她们如果想要有女人味就必须文静。或许男性文化鼓励男孩和男人支配谈话并且更经常打断谈话，而且健谈和频繁打断话头的男性不会为此受到批评。研究性别对交流所产生的作用的专家们针对沟通模式和沟通风格方面的这些差异进行探究，以便了解在男女对话中为什么会产生误解。误解的产生常常是因为他们的对话风格和方式存在极大的差异。为了能学会更好地和异性交流，我们有必要认识这些差异。C. 1

31、ther, but their favorite games are very often quite different. Tannen and other researchers on this topic have found that young boys, say ages 8 though 12, tend to play outside the house rather than in the house, and they play in large groups that are hierarchically structured. A group of boys gener

32、ally has a leader who tells the other boys what to do and how to do it.

33、s well as salary differences between men and women belonging to the four categories listed in the table. First, for women who have a high school diploma, their average income is $18,648 a year while men with the same learning earn $26,766 a year. Next, women who graduate with an associate degree ear

34、n $24,849 a year on average while men with the same degree earn $32,349 a year. Then, women with a bachelors degree earn $29,284 a year and men with a bachelors degree earn $40,381 a year. Last, women with a masters degree earn $35,018 a year while men with the same degree earn more: $47,260 a year

35、on average. As we can see here, the more one learns, the more one earns. And this accounts for the fact that students all over the world are working hard for higher degrees.

Each bar represents a particular group of people with whom cellular phone users communicate. Starting from the first bar on the left, we

37、see that 73% of cellular phone users use their mobile phone to communicate with friends or family. Then, moving to the right, we see 48% of cellular phone users use their phone to communicate with their co-workers, 39% with other business associates, 31% with customers and 11% with others. As we can

38、 see, the cellular phone is most frequently used by people as a means of conveying personal or private messages.

39、and cost, the cellular phone will become more and more popular.Task 3 This is a pie chart showing how on-the-job communication time is spent. As we can see, 55% of peoples on-the-job communication time is spent on listening, 13.3% on reading, 8.4% on writing and 23% on speaking. We can easily see th

40、e importance of listening skills in the workplace as people spend more than half of their total on-the-job communication time listening to other people talking. They have to use their listening skills effectively while they are at meeting, having discussions, on the phone, or taking instructions. Th

41、e second most important communication skill is speaking. People at work often have to talk to others. For example, they have to talk to their boss, supervisors, colleagues and customers. Reading and writing skills are also important. In order to keep pace with the latest developments and up-to-date

42、information in ones field, one has to read extensively: books, journals, magazines, newspapers and information on the Internet. Writing is important at work as well. Jobs involving research papers, memos, reports, etc. all require effective writing skills. In fact, whatever kind of job one has, one

43、needs to be good at these four basic communication skills. Task 4This is a line graph showing the number of children aged 12 and under who were diagnosed with HIV and died of AIDS from 1985 to 1995.As we can see, during a ten-year period of time, the number of HIV-infected children rose from 250 in

44、1985 to 6,700 in 1995. In other words, the number of HIV-infected children under 12 increased by almost 3,000%, or nearly 30 times over a ten-year period of time and during the same period of time 3,811 children died of Aids. This is a heartbreaking fact, and in the majority of cases children acquir

45、e HIV from their infected mother during pregnancy, labour, delivery or, after birth, through breastfeeding. Also, a small number of children acquire HIV infection as a result of receiving unscreened infected blood or blood products.Therefore, the most effective way to reduce the number of children w

46、ho become infected with HIV is to prevent HIV infection in parents-to-be. This requires strengthening of family-planning service. Of course, health education is also very important. People need to know that children can become infected with HIV. At the same time more care and support should be given

47、 to the HIV-infected children so that they can live a longer and better life.Unit5Task 2 Vocabulary DevelopmentB enacted implement intractable impact fragile payoffs prosecuted accountable compliance pettyTask 3 TranslationB. 当前是一个信息即时交流的时代，要想掩盖恶行越来越难，因为眼下私人侦探、走漏政府内部信息的人、愤愤不平的竞争对手以及那些刨根问底的记者们都会把那些贪污

48、腐败的官员和奸商暴露出来。由于腐化堕落会断送事业前程，所以曝光是一种重要的威慑力量。仅去年一年，被丑闻拉下台的就有乌克兰总理、南非副总统、巴西执政党领袖、肯尼亚政府的几名地位显赫的部长以及美国众议院多数党领袖。但是要确保腐败丑闻不会像色情电视剧那样重复上演，就必须进行系统的变革。领导层的变革在诸如世界银行、经济合作与发展组织、联合国、透明国际以及国际商会等重点机构已经展开或者即将展开。改革后的新领导班子应该与非政府组织以及其他重要机构（如出口信贷机构、国际执法部门等）领导人携手合作，以便制定全面的反腐战略，就近期和中期行动达成共识。C. 1.
