But while this pattern may be universal, our awareness of silence differs dramatically acro

2、ss cultures.What one culture considers a confusing or awkward pause may be seen by others as a valuable moment of reflection and a sign of respect for what the last speaker has said. Research in Dutch (荷蘭語) and also in English found that when a silence in conversation stretches to four seconds, peop

3、le start to feel uneasy. In contrast, a separate study of business meetings found that Japanese people are happy with silences of 8.2 seconds nearly twice as long as in Americans meetings.In Japan, it is recognised that the best communication is when you dont speak at all. Its already a failure to u

4、nderstand each other by speaking because youre repairing that failure by using words.In the US, it may originate from the history of colonial (殖民地的) America as a crossroads of many different races. When you have a complex of difference, its hard to establish common understanding unless you talk and

5、theres understandably a kind of anxiety unless people are verbally engaged to establish a common life. This applies also to some extent to London.In contrast, when theres more homogeneity,_perhaps its easier for some kinds of silence to appear. For example, among your closest friends and family its

6、easier to sit in silence than with people youre less well acquainted with.語篇解讀：本文主要講述了談話中的沉默文化。盡管交談中出現(xiàn)停頓是普遍存在的，但我們對沉默的認識在不同的文化中有著巨大的差異。不同的文化中沉默時間不同，對于沉默的看法也不同。1Which of the following people might have the longest silence in conversation?AThe Dutch.BAmericans.CThe English.DThe Japanese.解析：選D細節(jié)理解題。根據(jù)第

7、二、三段內(nèi)容可知，日本人在談話中沉默時間最長。故選D。2What might the Japanese agree with in conversation?ASpeaking more gives the upper hand.BSpeak out what you have in your mind.CGreat minds think alike without words.DThe shorter talking silence, the better.解析：選C推理判斷題。根據(jù)第四段首句可知，在日本，一般認為最好的交流是一句話不說的時候。因此推斷日本人認為“偉大的心靈，無言而喻”。故

8、選C。3What can we learn from the text?AA foursecond silence in conversation is universal.BIts hard for Americans to reach a common agreement.CEnglish speakers are more talkative than Japanese speakers.DThe closer we and our family are, the easier the silence appears.解析：選D推理判斷題。根據(jù)文章最后一句可知，親密的人之間更容易出現(xiàn)沉默

9、，因此我們和家人越親密，沉默越容易出現(xiàn)。故選D。4What does the underlined word “homogeneity” in the last paragraph mean?ASimilarity.BContradiction.CDiversity.DMisunderstanding.解析：選A詞義猜測題。根據(jù)下文的舉例可知，越親密的人，越容易出現(xiàn)沉默，因此推斷畫線句表示相比而言，當有更多相似時，也許沉默更容易出現(xiàn)。故畫線詞意思與similarity意義相近。故選A。BPlant cloning has been an agricultural technique used

10、by farmers and gardeners for centuries. Grafting (嫁接) is a common form of plant cloning. Many plants in nature actually clone themselves and reproduce asexually (無性生殖地)Cloned plants are much more predictable than normal plants, so their yield (產(chǎn)量) is more reliable. Cloned plants also reproduce faste

11、r, limiting the amount of time between planting and harvesting. It is also often cheaper to produce seeds through cloning than through traditional methods. Plants can essentially be optimized so that farmers or individual growers always have the best seeds available. With higher yield at a faster ra

12、te, farms can produce more food for more people while decreasing overall costs.Cloning can be used to wipe out diseases that previously killed off entire fields of crops. This would make plants immune to the kinds of diseases that farmers and gardeners around the world fear each year. Crop failures

13、due to disease and virus could become a thing of the past. Also, plants that are near extinction can be brought back to life through cloning.Through cloning scientists can develop super fruits and vegetables of superior (更好的) nutritional quality. This could make for a healthier population overall. T

14、his has already been done through selective pollination (授粉), and genetic cloning could take it to the next level.By plant cloning we have a population of identical plants and all these plants equally suffer from the same diseases, but in nature the weak would die and the strong would survive. While

15、 there are some dangers to consider with plant cloning, there are plenty of benefits that could prove vital to the propagation (繁衍) of the human species.5The underlined word “optimized” in Paragraph 2 is closest in meaning to “_”AgrownBproducedCperfectedDexamined解析：選C詞義猜測題。根據(jù)“so that farmers or indi

16、vidual growers always have the best seeds available”可知，optimize與perfect的意思相近。6According to the text, cloned plants _.Ahave lower yield than normal plantsBneed less care from peopleCprevent various kinds of diseasesDhave a shorter growth cycle解析：選D細節(jié)理解題。從第二段中的“Cloned plants also reproduce faster, lim

17、iting the amount of time between planting and harvesting.”可知，克隆的植物的生長周期短。7What is the main purpose of the text?ATo warn the negative effects of plant cloning.BTo show different kinds of plant cloning.CTo predict the future of plant cloning.DTo introduce the advantages of plant cloning.解析：選D寫作目的題。文章的

18、第二、三、四段都是在介紹植物克隆的好處，所以本文的目的是介紹植物克隆的好處。CWe are all fascinated by mysteries. To some extent we love to expect strange phenomenon occurring before us. Here are some amazing unsolved mysteries.The Georgia GuidestonesOn one of the highest hilltops in Elbert County, Georgia stands a giant granite monument

19、 (花崗巖紀念碑). Carved in eight different languages on the four giant stones are 10 Guides.The origin of this strange monument is covered in mystery because no one knows the true identity of the man, or men, who constructed it. All we know is that in June 1979, a man identifying himself as RC.Christian a

20、nnounced that he would build something to convey a message to mankind, but to date, no one knows who RC.Christian really was.Bermuda TriangleThe Bermuda Triangle is a triangular area of the Atlantic Ocean. Many planes, ships, and boats are said to have disappeared in this triangle without a trace, w

21、hich led to the belief that “supernatural” forces exist in this area of the sea.Could there truly be an unnatural force at work in this geographical triangle or are these disappearances merely coincidence? Either way, numerous people remain unwilling to step over the boundary line into the Devils Tr

22、iangle.Loch Ness MonsterThe Loch Ness Monster is a legendary animal that supposedly lives in the depths of Loch Ness, a long narrow lake located in rural Scotland.Stories concerning the monster date back to the 6th century AD. Over the years thousands have reported seeing a long neck appearing from

23、the water with a small head of an unknown creature. Pictures have even been taken of this “creature”， but most scientists refuse to believe any creature of this kind lives in the Loch Ness. So far, the evidence is inadequate, and the controversy continues.語篇解讀：本文是一篇說明文。文章主要介紹了世界上三大未解之謎，包括佐治亞州的巨石陣、百慕

24、大三角和尼斯湖水怪。8Why is the Georgia Guidestones mysterious?AIt is on one of the highest hilltops in Elbert County.BThere are eight different languages on the stones.CThe person who built it remains unknown.DR. C. Christian could convey a message to mankind.解析：選C細節(jié)理解題。根據(jù)The Georgia Guidestones部分第二段內(nèi)容可知，巨石陣

25、很神秘是因為沒有人知道是誰建造了它。故選C。9Why are people unwilling to enter the Bermuda Triangle?AIt is too remote from land.BThe chance of surviving is slim there.CThere are supernatural forces in the area.DAll transportations have disappeared there.解析：選B推理判斷題。根據(jù)Bermuda Triangle部分第一段第二句可知，在百慕大三角經(jīng)常有飛機、輪船和小船失蹤；由此可推知，在百

26、慕大三角人們幸存的可能性很小，所以許多人不愿意進入百慕大三角地帶。故選B。10What can we know about Loch Ness Monster?AIt existed in the 6th century AD.BIt is said to have a long neck and a large head.CIt has been living in Loch Ness Lake for a long time.DPeople havent reached an agreement on its existence.解析：選D細節(jié)理解題。根據(jù)最后一段第一句可知，關于水怪的故事

27、始于公元6世紀，并不是說水怪出現(xiàn)在公元6世紀，故排除A項；根據(jù)最后一段第二句中的“with a small head”可知，B項錯誤；根據(jù)最后一段倒數(shù)第二句可知，大多數(shù)科學家都不相信有這種水怪生活在尼斯湖中，故排除C項；根據(jù)最后一段最后一句可知，D項“人們對它的存在沒有達成一致意見”符合原文。故選D。.閱讀七選五Too often an inappropriate view gets around us that it is our physical conditions that make us happy or unhappy. As a consequence, physical con

28、ditions have been overstated._1_， that is, good standard of living, high goals that we want to obtain, surrounding ourselves with a nice house, nice car, nice clothes, etc. _2_. But many times once we obtain our goals and are surrounded by what we thought would make us happy, we are still unhappy.Al

29、so on the other end of the stick, many, many people are unhappy now, because they have not obtained their goals and _3_， which, consequently, adds to their dissatisfaction with life.So this is why so many people keep themselves for most of their lives in a state of “incompleteness” and unhappiness,

30、and this is why so many super successful people still arent happy. The reason is that _4_. They think that the Universe should give them what they want first and then theyll be happy. But that just puts a barrier in between them and happiness because of the way the Universe is set up.The message her

31、e is to understand that your desires tell you where you want to put your focus in your life, however, _5_. You make yourself happy from the inside out, not the outside in. Do not require certain conditions be met for your happiness, because it wont work anyway.AWe have different ways to get what rea

32、lly makes us happyBthey dont have what they want in lifeCWe set out to get happy by trying to control all the wonderful conditions around ourselvesDthey are never there to be found in lifeEthey should not control your happiness in this momentFWe may think this is the key to our happinessGthey dont r

33、ealize how to get happy語篇解讀：本文是一篇議論文。本文談論的是人們認為的幸福實際上并沒有給人們帶來幸福，作者就如何才能得到真正的幸福提出了自己的觀點。1選C根據(jù)上文中的“physical conditions”及下文中的“good standard of living .nice clothes”可知，C項“我們通過努力掌控我們身邊美好的物質(zhì)條件來獲取幸?！迸c上文相呼應，與“that is”后面的解釋也一致。故選C。2選F根據(jù)語境可知，很多時候當我們擁有了良好的生活標準，實現(xiàn)了我們想要的目標，擁有了漂亮的房子、車子、衣服時，我們可能就認為這是幸福的關鍵所在了。F項“我們

34、可能會認為這就是幸福的關鍵了”銜接上文，并與下文構成轉折，符合語境。故選F。3選B根據(jù)語境可知，此處分析了不快樂的人的心理。根據(jù)“because they have not obtained their goals”可知，許多人不快樂是因為沒有達到目標，and連接和前面并列的內(nèi)容。B項“他們沒有擁有生活中想要的”也是人們不快樂的原因，并且和下文聯(lián)系緊密。故選B。4選G上文提到，擁有了良好物質(zhì)條件的人仍然感到不幸福，沒有達到目標的人也感到不幸福，此處作者給出他們感到不幸福的理由，因為“他們沒有意識到如何獲得快樂”。由此可知，G項與上文銜接緊密。故選G。5選E上文提到，本文傳遞的信息就是要讓你明白，你的欲望會告訴你，在生活中要看重什么。由however可知，后面的內(nèi)容應與前面的敘述形成對比，所以E項“這時這些欲望不應該左右你的幸福感”符合語境。故選E。7
