Trufa.For some reason unknown to them，Ole and Trufa had_16_all the rains and winds.But Ole and Trufa believed the answer_17_in the great love they bore one another.One leaf can do_18_for another when the wind blows，and the rain pours._19_，Ole encouraged Trufa at every opportunity.At times during cold and stormy nights，Ole would_20_，“My time has come，Trufa，but you hang on！”“What for？”Trufa asked.“Without you，my life is_21_.If you fall，I'll fall with you.”One day just as Trufa spoke these words，what they two had_22_all these months happeneda wind came up and tore Ole_23_from the branch.Soon Ole disappeared from sight and Trufa was left all alone on the tree.As long as it was still day，Trufa managed somehow to_24_her sorrow.But when it grew dark and cold，she_25_despair.Somehow she felt that the blame for all the leaves'_26_was laid on the tree.Leaves fell，but the trunk stood tall，and was_27_rooted in the earth.No wind，or rain could_28_it.One night，Trufa dozed off.The next morning，to her_29_she found that she was no longer_30_on the tree.The wind had blown her down while she was asleep.She_31_now that she wasn't just a leaf that_32_the wind，but that she was_33_of the universe.Next to her lay Ole，and they_34_each other with a love.This wasn't a love that depended on chance，but a love as powerful and_35_as the universe itself.【语篇解读】 文章主要讲述了两片叶子的爱情故事。16A.suffered BsurvivedCescaped Davoided解析文章一开始就提到了只有两片树叶还留在树上，因此此处用survive表示“幸免于，幸存”。suffer“遭受”；escape“逃脱，避开”；avoid“避免”均不符合语境。答案B17A.resulted BbroughtClay Dcame解析lie in在于。语境为“他们认为答案在于他们之间产生的爱”。答案C18A.little Bmuch Cfavor Dfew解析根据句意可知，在大风大雨中一片树叶能为另一片树叶所做的是很少的，故用little表示。答案A19A.But BStill CThough DOtherwise解析Ole仍然每次都鼓励着Trufa。still“仍然，还”。but表示转折，though表示让步，otherwise“否则”均不符合语境。答案A20A.complain BsayCrequest Dannounce解析根据上下文可知，这里是说“在寒冷的暴风雨的夜晚，Ole就会跟Trufa说”。答案B21A.regretful BsenselessCdifferent Dhappy解析没有你，“我”的生命就没有意义。senseless“无意义的”；regretful“后悔的，抱歉的”；different“不同的”；happy“高兴的”。答案B22A.expected BintendedCfeared Dimagined解析下文中提到一阵风吹来，Ole被吹掉了，这是两片叶子数月来一直害怕的事情。fear“害怕，畏惧”；expect“盼望”；intend“打算，企图”；imagine“想象，设想”。答案C23A.open Bactive Cloose Dalive解析从下文的“Soon Ole disappeared from sight”可知Ole被风从树上吹下来了。loose符合语境。答案C24A.appreciate BwinCafford Dbear解析两片赖以生存的叶子中的一片被风吹掉了，剩下的一片肯定是很难过的，但是在白天Trufa还是将难过埋藏在心里。答案D25A.stepped into Bcaught inCtook in Dsank into解析上文提到Trufa白天强忍悲痛，到了晚上变得非常绝望，故选sink into “渐渐进入(消极、不快等)状态”。答案D26A.fortunes BchangesCmisfortunes Dchances解析她感到落叶的不幸遭遇应该归咎于大树。misfortune“不幸”，此处指的是被大风吹落的不幸遭遇。fortune“幸运，运气”，change“改变”；chance“机会，机遇”。答案C27A.firmly BslightlyCdeeply Dtightly解析句意为“叶子虽然掉了，但是树干仍然高高耸立，根深深地扎在泥土中”。firmly“坚定地，稳固地”；slightly“轻微地，稍微”；deeply“深深地”；tightly“紧紧地”。答案A28A.upset BblowCtouch Dmake解析上文中提到“树干仍然高高耸立，根深深地扎在泥土中”，因此没有什么风雨能够吹倒大树。upset“使倾覆，碰倒，打翻”；blow“吹”；touch“接触，触摸”；make“制造”。答案A29A.delight BamazementCdisappointment Dsatisfaction解析从下文提到的“The wind had blown her down”，可知Trufa已经被风吹掉了，当她发现时肯定是惊讶的，故用amazement“惊愕，惊异”。delight“高兴，欣喜”；disappointment“失望”； satisfaction“满足，满意”。答案B30A.hanging BstayingCleaving Dsticking解析Trufa已经被风吹到了树下，因此她已经不在树上了。hang悬挂，符合题意。答案A31A.spoke BrememberedCconsidered Dknew解析本句说的是Trufa当时心里的想法，因此know“知道”符合题意。答案D32A.decided on Bheld onCconcentrated on Ddepended on解析语意为“她不仅仅是一片依靠风的叶子而是宇宙的一部分”。答案D33A.some Bany Cpart Done解析part of“的一部分”，意思为“她是宇宙的一部分”。答案C34A.presented BtreatedCprovided Dgreeted解析Ole与Trufa都从树上被吹落下来，他们见面之后当然要相互问候了，故选greet。答案D35A.pure Bbrief Cpermanent Dfree解析与宇宙一样的爱当然是强大的和持久的，故选permanent“永久的，持久的”。答案C第二部分：阅读理解(共20小题；每小题2分，满分40分)阅读下列短文，从每题所给的四个选项(A、B、C和D)中，选出最佳选项。AIf you travel to a new exhibit at the San Francisco Conservatory of Flowers，you will have chances to see some meat­eating plants.Take bladderworts，a kind of such plant，for example.They appear so small and grow in a quiet pond.But these are the fastest­known killers of the plant kingdom，able to capture a small insect in 1/50 of a second using a trap door!Once the trap door closes on the victim，the enzymes(酶)similar to those in the human stomach slowly digest the insect.When dinner is over，the plant opens the trap door and is ready to trap again.Meat­eating plants grow mostly in wet areas with soil that doesn't offer much food value.In such conditions，these amazing plants have developed insect traps to get their nutritional needs over thousands of years.North America has more such plants than any other continent.Generally speaking，the traps may have attractive appearance to fool the eye, like pitcher plants，which get their name because they look like beautiful pitchers (a container like a bottle) full of nectar(花蜜)The Asian pitcher plant，for example，has bright colors and an attractive half­closed lid.Curious insects are tempted to come close and take a sip，and then slide down the slippery(光滑的)slope to their deaths.Hair­like growths along the pitcher walls ensure that nothing can escape，and the digestive enzymes can get to work.A tiny insect can be digested in a few hours，but a fly takes a couple of days. Some of these pitchers are large enough to hold two gallons.Meat­eating plants only eat people in science fiction movies，but sometimes a bird or other small animals will discover that a pitcher plant isn't a good place to get a drink.【语篇解读】 本文是一篇说明文，介绍了一些特别的植物靠捕食动物获得生长所需养分的“食肉植物”。36From the first paragraph，we can know that bladderworts can_.Acapture 50 small insects in a secondBcapture an insect in the shortest timeCbe found floating on a quiet lakeDdigest an insect in 1/50 of a second解析细节理解题。第一段指出，bladderworts能在1/50秒的时间内捕获一只小昆虫，是植物中已知的捕获动物速度最快的，因此选B。答案B37If the trap door of a meat­eating plant is closed，the plant_.Ais fooling insects into taking a sipBis producing nectarCis tempting insects to come closeDis enjoying a dinner解析细节理解题。第二段说，一旦“陷阱门”将猎物关起来，类似于人胃里的那些消化酶就开始慢慢地消化它了，由此判断D正确。答案D38Meat­eating plants can grow in wet and poor soil because they_.Acan get nutrition from animalsBdon't need much food valueCcan make the most of such conditionsDhave developed digestive enzymes解析推理判断题。这些植物生长在潮湿贫瘠的土壤中，为获得生长所需的养分，在数千年的进化中，它们演化出了捕获昆虫的“陷阱”，由此推出它们主要从动物中获取养分，而不是从土壤中获取养分。答案A39Which of the following is the picture of the Asian pitcher plant?解析推理判断题。根据第四、五、六段可知亚洲捕虫草主要有这些特征：状如水瓶，颜色鲜亮，有半掩的盖子，综合此三项可知，只有A项最合适。答案ABResearchers from the University of North Carolina in Chapel Hill found that coral coverage in the Indo­Pacific­an area stretching from Indonesia's Sumatra island to French Polynesiadropped 20 percent in the past two decades.About 600 square miles of reefs have disappeared since the 1960s，the study found，and the losses were just as bad in Australia's well­protected Great Barrier Reef as they were in poorly managed marine reserves in the Philippines.“We found the loss of reef building corals was much more widespread and severe than previously thought，”said John Bruno，who conducted the study along with Elizabeth Selig.“Even the best managed reefs in the Indo­Pacific suffered significant coral loss over the past 20 years.”The study，which examined 6,000 surveys of more than 2,600 Indo­Pacific coral reefs done between 1968 and 2004，found the declines began earlier than previously estimated and mirror global trends.The United Nations has found close to a third of the world's corals have disappeared，and 60 percent are expected to be lost by 2030.The Indo­Pacific contains 75 percent of the world's coral reefs and provide a home for a wide range of marine plants and animals.They provide shelter for island communities and are key source of income，mostly from the benefits of fishing and tourism.“ Indo­Pacific reefs have played an important economic and cultural role in the region for hundreds of years and their continued decline could mean the loss of millions of dollars in fisheries and tourism，”Selig said in a statement.“It's like when everything in the forest is gone except for little twigs(小树)”【语篇解读】 本文是科普阅读。由于天气变暖、疾病和海岸开发等原因，世界上大量的珊瑚礁在消失，特别是在印度洋、太平洋地区。40What do we know about Great Barrier Reef from the passage?AIt is well­protected and in much better condition than elsewhere.BIt also suffers a bad coral loss though it is well­protected.CBecause it is well­protected，reefs have never disappeared.DIt is as badly managed as the marine reserves in the Philippines.解析细节理解题。从第三段可知，在澳大利亚的大堡礁、珊瑚礁也在消失，情况跟菲律宾的一样糟糕。答案B41We can infer from the passage that_.Athe Indo­Pacific has the largest coral coverageBreefs only began to disappear in the 1960sCcoral loss has only happened in some parts of the worldDhuman factors play an important role in coral loss解析推理判断题。从文章第一段的介绍可知，珊瑚礁的消失与三个因素有关，而气候变暖和海岸开发都有人为因素在里面。答案D42In what way are coral reefs important?AMany marine plants and animals live in them.BThey can be used as building materials.CMany marine plants and animals feed on them.DThey provide shelter for island residents.解析细节理解题。文章倒数第二段第一句说明，珊瑚礁为很多海洋动植物提供了“家”。答案ACHow much rain has fallen on the earth in the past？Man has not always kept weather records.Because scientists need a way to learn about past rainfall，they study the tree rings.A tree's trunk(树干)grows bigger each year.Under its bark(树皮)，a tree adds a layer of new wood each year it lives.If you look at a tree stump(树桩)，you can see the layers which are called annual rings.On some trees，all of the rings are of the same width.But the ponderosa pine(美国黄松)that grows in the American southwest have rings in different width.The soil in the southwest is dry.The pines depend on rainfall for water.In a year of good rainfall，they form wide rings.In a dry year，they form narrow ones.Scientists don't have to cut down a pine tree to study its rings.With a special tool，they can remove a narrow piece of wood from the trunk without harming the tree.Then they look at the width of each ring to see how much rain fell in the year it formed.Some pines are hundreds of years old and have hundreds of rings.These rings form an annual record of past rainfall in the southwest.【语篇解读】 本文主要讲了树的年轮。43We could infer from the story that_.Aa tree grows faster when it has a lot of waterBscientists can cut down trees to study tree ringsCpine trees form wide rings every yearDthe ponderosa pine grows in the southwest解析推理判断题。由第三段第四、五、六句可知答案为A。答案A44A tree grows a new layer of wood_.Aeach week Bwhenever it rainsCevery year Devery season解析细节理解题。由第二段第一句可得到答案。答案C45All in all，this story is about_.Awhy the tree trunks grow biggerBscientists study tree ringsCtrees that lived hundreds of years agoDthe ponderosa pine in the southwest解析推理判断题。本文主要讲述了树的年轮和科学家对它的研究。答案B46Why do the scientists study the width of the tree rings?AThey want to know how big the tree will grow.BScientists want to move the pine trees.CThe trees depend on rainfall for water.DThe rings tell them how much rain has fallen.解析推理判断题。见全文最后一句。答案DDHidden in our subconsciousness(潜意识) is a perfect mental picture.We see ourselves on a long trip that goes across the continent.We are traveling by train.Out of the windows，we think in the passing scene of cars on nearby highways，of children waving at a crossing，of cattle feeding on a distant hillside，of smoke pouring from a power plant，or row upon row of corn and wheat，of flat lands and valleys，of mountains and rolling hills，of city skylines and village halls.But uppermost in our minds is the final destination.On a certain day at a certain hour，we will pull into the station.Bands will be playing and flags waving.Once we get there，so many wonderful dreams will come true and the pieces of our lives will fit together like a completed jigsaw(拼图玩具) puzzle.How restlessly we pace the aisles(通道)，condemning the minutes for loiteringwaiting，waiting，waiting for the station.“When we reach the station，that will be it！” we cry，“When I'm 38.” “When I buy a new 450SL Mercdes Benz！” “When I put the last kid through college.” “When I have paid off！” “When I get a promotion.” “When I reach the age of retirement，I shall live happily ever after！”Sooner or later，we must realize there is no station，no one place to arrive at once and for all.The true joy of life is the trip.The station is only a dream.It constantly outdistances us.“Relish(appreciate) the moment” is a good motto，actually it isn't the burdens of today that drive man mad.It is the regret over yesterday and the fear of tomorrow.Regret and fear are twin thieves who rob us of today.So stop pacing the aisles and counting the miles.Instead，climb more mountains，eat more ice cream，swim more rivers，watch more sunsets，laugh more and cry less.Life must be lived as we go along.Then the station will come soon enough.【语篇解读】 人生如旅行，重要的是旅行的过程和途中的风景，而不是目的地。不要懊悔过去，也不要恐惧未来，要好好珍惜和享受现在。47Why does the author describe the mental picture?ATo lead us into a perfect world.BTo let people enjoy the scenery.CTo introduce an actual trip of his.DTo compare it to our life's journey.解析推理判断题。在第一段，作者详细描述了我们潜意识中在旅行途中看到的美景，但接下来两段描述了现实生活中我们注重目的地的事实，由此可知作者描述这幅心灵图像是为了将现实旅行与其对比。答案D48How do people feel when they're on their trip?APuzzled. BHappy. CRelaxed. DImpatient.解析推理判断题。根据第二段“How restlessly we pace the aisles(通道).”可以了解人们经过通道时的那种焦躁不安的情绪，故选D。puzzled“迷惑的”；happy“高兴的”；relaxed“放松的”。答案D49What does the author mean by “Regret and fear are twin thieves who rob us of today” in Paragraph 5?ARegret and fear are responsible for the loss of today.BWe must be careful of the two thieves：regret and fear.CRegret and fear stop us from enjoying our present life.DWe're frequently challenged by the two：regret and fear.解析句子理解题。根据倒数第二段中“It is the regret over yesterday and the fear of tomorrow”可知，对过去的懊悔和对未来的恐惧使得人们无法享受现在，故C项最佳。答案C50Why does the author write the passage?ATo teach us a good lesson.BTo tell us the right attitude to life.CTo advise us to forget our worries.DTo stop us wandering along the aisles.解析写作意图题。作者试图告诉人们要树立正确的人生观，不要懊悔过去，也不要恐惧未来，要好好珍惜和享受现在。答案BEUK residents take over 40m holidays abroad and more than 100m overnight stays in this country each year.Choices made about where to go，how to get there and what to do while there can either benefit or harm the environment.While on holidayMany of the things you can do to be greener on holiday will be the same things you can do at homebut there are also some extra things too，like avoiding gifts made from endangered species.Here are some suggestions：·Making the most of locally produced food and drink，and local activities and attractions will support people in the area you are visiting and reduce the need for further environmental impact from transport；·Switching off any air conditioning，heating and lights when you're not using your accommodation will help reduce climate change effects；·Try not to waste watersome countries suffer from water shortages and saving water can help avoid damage to natural habitats.Endangered speciesSome gifts and foods available in some countries can be made from endangered plants or animals，for example，animal skins，ivory，orchids，caviar，or coral.Check before you buy，but if in doubt avoid animal and plant gifts.More details of the types of products to avoid and illegal trade hotspots can be found on the Souvenir Alert webpage.Making a positive contribution to the place you are visitingThere are ways in which your holiday can help support local people and the environment：·There are many opportunities to volunteer and help with projects that conserve and improve habitats and nature reserves；·When you are away，or if you are looking for somewhere to visit in the UK，you can support projects or attractions which protect wildlife，such as nature reserves and conservation projects.【语篇解读】 本文是应用文。文章介绍在海外旅行时，怎样保护环境，选择绿色活动。51If given a title to the passage，a best possible one would be_.ATravel Abroad：Don't Harm the EnvironmentBHolidays：Greener choicesCHolidays Abroad：What to Do and What Not to DoDTravel Abroad：Minimise Environmental Impact解析主旨大意题。第一段中“在海外旅行时，怎样保护环境”Choices made about where to go，how to get there and what to do while there can either benefit or harm the environment是本文的主题句。答案B52The Souvenir Alert webpage gives you information about_.Asouvenirs availableBforbidden souvenirsCwhere to trade souvenirsDall types of products解析细节理解题。B项forbidden souvenirs与原文中“非法旅游纪念品”交易的含义最接近。答案B53What can you do to help reduce climate change effects?ADon't waste water.BMake the most of locally produced food and drink.CSave electricity.DDon't go around too much.解析细节理解题。从第一部分第二条Switchi
