B.A phenomenon is noted and explanations for it are presented.
C.A hypothesis is presented and arguments against it are cited.
D.A prognosis is made and evidence supporting it is discussed.答案：B解析：结构题。第四段第一句话意为For complicated reasons，American Indian poetry has basically been ignored by non-lndian cultures，这是一种现象。故本题选B。参考译文：大多数北美人对美国印第安人的文化和历史知之甚少，这是很不幸的事实。学者们研究了这些事实，但是他们还没有成功地让这些结论广为人知。因此，很少有人知道美国印第安人有叙事诗，在欧洲人到来之前的很长一段时间，他们表演戏剧，推行政治，进行交易。想要更全面地欣赏美国印第安人丰富文化的方式之一是去研究其诗歌，因为诗歌在任何文化中都是艺术最中心和最清晰的表达。对我们来说研究美国印第安人的诗歌尤其重要，因为诗歌可以创造一个背景，这个背景可以给予我们有关工艺、史前古器物和一些孤立的事实呈现整体表达，不管你愿意与否.这已经成功地让许多美国人注意到这些事实。一个关于美国印第安人诗歌的调查甚至揭示了一系列公然挑衅简单泛化诗歌的思想和技巧。然而，杰罗尔德·拉姆齐冒险做了概述，这一概述是为了让外行的读者至少能够感受到美国印第安人诗歌的样貌。总之，他写道，诗歌代表了“一种口头的、固化的、传统的和匿名的艺术形式”，它通过强调现实中“神话和神圣”部分的方式来呈现，“通过公共表演而繁荣起来……通过技艺高超演唱者演绎观众已然知道诗歌中所包含的个人故事”。并且，诗歌重视表演者，因为他们“有能力去探索他们的戏剧性的材料，并将他们(的故事)与漫长的岁月相结合”，而不是为了他们的“情节创作”。因为，诗歌属于具有高度种族中心主义的部落人民，对于他们的文化“我们仍然知之甚少”，因此“看起来更简洁、更神秘”。拉姆齐忽略了美国印第安人诗歌的另一个特色：功能性。无论是唱、吟诵或者背诵，无论是出于娱乐或作为任务的一部分(例如治愈病人或磨玉米)而进行的仪式上的表演，或者无论是个人背诵还是组队背诵，诗歌总是完全地融入到普通人的生活中。由于一些复杂的原因，美国印第安人的诗歌基本被非印第安人的文化给忽略了。肯尼斯·林肯写道，听不到美国印第安人的声音是因为“一部分是……部落混乱的悲剧，一部分是错译，一部分是关于文学的误解，还有一部分是对文化的不重视”。布莱恩·斯旺补充了一个解释：部落诗歌是口头的，而欧洲人抵达这个新世界的时候是带着“书写是首位”这种根深蒂固的信仰来的。结果，欧洲殖民者发现很难想象如果没有书面文字诗歌还能够存在。因此在欧洲人抵达这里之前的很长一段时间内，美国印第安人已经取得了一些成就，这些成就与欧洲所说的文学旗鼓相当。结果，欧洲人完全没有表达出美国印第安人诗歌的活力。 -

问答题◆Topic 11：On Bicycle Theft Questions for reference: 1) Is bicycle theft commonly seen on campus? 2) What are the causes for the theft? 3) What can universities you to stop such phenomenon?正确答案： 【参考答案】
Bicycle theft is very common on campus, which is immoral and illegal. And it is damaging to the academic image of the colleges and universities.

第10题：
问答题Practice 2 You should spend about 40 minutes on this task. Write about the following topic: Many people are busy with work and do not have enough time to spend with families and friends. Why does this happen? What are the effects of this on family life and society as a whole? You should write at least 250 words.正确答案： 【参考范文】
Imagine that you are in a car parked on the road during rush hour for more than one hour. You may be regretful for wasting such a long time and losing time to get together with family. This question will be the main topic of the following essay; besides, it will also tall about its effects at the same time.
As for those brief-case men and white collar, they have to cope with a lot of issues at work. And thus only leave their families a small amount of time. There are many reasons for this. Firstly, living in modern society, it is impossible to avoid the pressure from both inside and outside. In order to maintain a good public praise or just get a further promotion, people not only care about their own feelings but those of others’ as well. Secondly, the world is full of material stimulation, encouraging people to chase their happiness, materially. Without money, no one can live in society in his most-wanted way. In order to own a satisfactory living standard, they have no choice but work harder. Last but not least, the advances of modern technology enable people to communicate with each other without seeing each other. This is almost a tragedy for mankind. If we spend all our time on the Internet, we will lose so many traditional ways like face-to-face talking and body language.
Also, the influence of this issue should never be neglected for society: Cumulative stress from work becomes the potential health killer. People are easily infected with psychological illnesses like anxiety, eccentricity and insomnia. In addition, due to materialism and realism, society as a whole has easily become money-oriented, where people make judgments of achievements just according to the materials. Finally, over-dependence on telecommunication leads to the lack of recalling traditions and rethinking of the history and culture, which is a shame for civilized people.
Naturally, a profession is fundamental for all modern city dwellers without any question. However, the family is the ultimate destination for them indeed.解析： 暂无解析 -

问答题Read the passage carefully and answer Questions 1 to 5. Answer each question in a maximum of 10 words. Remember to write the answers on the Answer Sheet. In the United States today, many people want a college education. However, almost half of the people who go to college now do not attend a four-year college. Instead, they go to a community college. The community college offers a two-year course of study in a wide range of subjects. It prepares some young people to go on to a four-year college. It trains others for jobs in business, government, or industry. Some people choose a community college because of cost. The tuition for a semester at a community college can be less than half the cost of a semester at a four-year college. Also, since these colleges are located in large communities, their students can save money by living at home. Community colleges are also useful for people who have jobs and who do not have time for a traditional four-year college. Some of these people take night courses at community colleges. Others complete long-distance courses, in which they stay at home and use video-tapes, audiotapes, and the Internet. Community colleges also serve high school graduates who only achieved low grades. Many of these students would not be admitted to a four-year college. If they do well, they may go on to a four-year college. Today, the country’s 1,500 community colleges have more than 10 million students. These colleges are making it possible for more and more people to continue their education. Questions: 1．What is the passage mainly about? 2．What does theyin paragraph 1 refer to? 3．In which fields does a community college provide job training? 4．Why do people often prefer to go to a community college? 5．What does the word tuitionin paragraph 3 mean?正确答案：
1.(the advantages of)community college 本文主要介绍了与普通高校相比,社区学院的各项优点,如:开设课程广泛、学费低以及适合各类学生进修等。
2.half of the people who go to college now ”instead”表意思转折,前后共享一个主语。
3.business, government, or industry 第二段最后一句提到社区学院在商务,政府和工业领域为学生提供职能培训。
4.low cost 第三段提到许多人出于费用考虑选择社区学院,因为它的学费低于四年制高校的一半,并且因为离家近很多学生可以直接住在家里从而节省住宿费。这是community college区别于其他院校最大的地方。
5.cost 本段提到许多人出于cost考虑选择社区学院,并且由第二句话可推断tuition与cost是近义词。tuition学费。解析： 暂无解析 -
