branch：Ole and 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.”O(jiān)ne 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.【語篇解讀】 文章主要講述了兩片葉子的愛情故事。16A.suffered BsurvivedCescaped Davoided解析文章一開始就提到了只有兩片樹葉還留在樹上，因此此處用survive表示“幸免于，幸存”。suffer“遭受”；escape“逃脫，避開”；avoid“避免”均不符合語境。答案B17A.resulted BbroughtClay Dcame解析lie in在于。語境為“他們認(rèn)為答案在于他們之間產(chǎn)生的愛”。答案C18A.little Bmuch Cfavor Dfew解析根據(jù)句意可知，在大風(fēng)大雨中一片樹葉能為另一片樹葉所做的是很少的，故用little表示。答案A19A.But BStill CThough DOtherwise解析Ole仍然每次都鼓勵(lì)著Trufa。still“仍然，還”。but表示轉(zhuǎn)折，though表示讓步，otherwise“否則”均不符合語境。答案A20A.complain BsayCrequest Dannounce解析根據(jù)上下文可知，這里是說“在寒冷的暴風(fēng)雨的夜晚，Ole就會(huì)跟Trufa說”。答案B21A.regretful BsenselessCdifferent Dhappy解析沒有你，“我”的生命就沒有意義。senseless“無意義的”；regretful“后悔的，抱歉的”；different“不同的”；happy“高興的”。答案B22A.expected BintendedCfeared Dimagined解析下文中提到一陣風(fēng)吹來，Ole被吹掉了，這是兩片葉子數(shù)月來一直害怕的事情。fear“害怕，畏懼”；expect“盼望”；intend“打算，企圖”；imagine“想象，設(shè)想”。答案C23A.open Bactive Cloose Dalive解析從下文的“Soon Ole disappeared from sight”可知Ole被風(fēng)從樹上吹下來了。loose符合語境。答案C24A.appreciate BwinCafford Dbear解析兩片賴以生存的葉子中的一片被風(fēng)吹掉了，剩下的一片肯定是很難過的，但是在白天Trufa還是將難過埋藏在心里。答案D25A.stepped into Bcaught inCtook in Dsank into解析上文提到Trufa白天強(qiáng)忍悲痛，到了晚上變得非常絕望，故選sink into “漸漸進(jìn)入(消極、不快等)狀態(tài)”。答案D26A.fortunes BchangesCmisfortunes Dchances解析她感到落葉的不幸遭遇應(yīng)該歸咎于大樹。misfortune“不幸”，此處指的是被大風(fēng)吹落的不幸遭遇。fortune“幸運(yùn)，運(yùn)氣”，change“改變”；chance“機(jī)會(huì)，機(jī)遇”。答案C27A.firmly BslightlyCdeeply Dtightly解析句意為“葉子雖然掉了，但是樹干仍然高高聳立，根深深地扎在泥土中”。firmly“堅(jiān)定地，穩(wěn)固地”；slightly“輕微地，稍微”；deeply“深深地”；tightly“緊緊地”。答案A28A.upset BblowCtouch Dmake解析上文中提到“樹干仍然高高聳立，根深深地扎在泥土中”，因此沒有什么風(fēng)雨能夠吹倒大樹。upset“使傾覆，碰倒，打翻”；blow“吹”；touch“接觸，觸摸”；make“制造”。答案A29A.delight BamazementCdisappointment Dsatisfaction解析從下文提到的“The wind had blown her down”，可知Trufa已經(jīng)被風(fēng)吹掉了，當(dāng)她發(fā)現(xiàn)時(shí)肯定是驚訝的，故用amazement“驚愕，驚異”。delight“高興，欣喜”；disappointment“失望”； satisfaction“滿足，滿意”。答案B30A.hanging BstayingCleaving Dsticking解析Trufa已經(jīng)被風(fēng)吹到了樹下，因此她已經(jīng)不在樹上了。hang懸掛，符合題意。答案A31A.spoke BrememberedCconsidered Dknew解析本句說的是Trufa當(dāng)時(shí)心里的想法，因此know“知道”符合題意。答案D32A.decided on Bheld onCconcentrated on Ddepended on解析語意為“她不僅僅是一片依靠風(fēng)的葉子而是宇宙的一部分”。答案D33A.some Bany Cpart Done解析part of“的一部分”，意思為“她是宇宙的一部分”。答案C34A.presented BtreatedCprovided Dgreeted解析Ole與Trufa都從樹上被吹落下來，他們見面之后當(dāng)然要相互問候了，故選greet。答案D35A.pure Bbrief Cpermanent Dfree解析與宇宙一樣的愛當(dāng)然是強(qiáng)大的和持久的，故選permanent“永久的，持久的”。答案C第二部分：閱讀理解(共20小題；每小題2分，滿分40分)閱讀下列短文，從每題所給的四個(gè)選項(xiàng)(A、B、C和D)中，選出最佳選項(xiàng)。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.【語篇解讀】 本文是一篇說明文，介紹了一些特別的植物靠捕食動(dòng)物獲得生長所需養(yǎng)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解析細(xì)節(jié)理解題。第一段指出，bladderworts能在1/50秒的時(shí)間內(nèi)捕獲一只小昆蟲，是植物中已知的捕獲動(dòng)物速度最快的，因此選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解析細(xì)節(jié)理解題。第二段說，一旦“陷阱門”將獵物關(guān)起來，類似于人胃里的那些消化酶就開始慢慢地消化它了，由此判斷D正確。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解析推理判斷題。這些植物生長在潮濕貧瘠的土壤中，為獲得生長所需的養(yǎng)分，在數(shù)千年的進(jìn)化中，它們演化出了捕獲昆蟲的“陷阱”，由此推出它們主要從動(dòng)物中獲取養(yǎng)分，而不是從土壤中獲取養(yǎng)分。答案A39Which of the following is the picture of the Asian pitcher plant?解析推理判斷題。根據(jù)第四、五、六段可知亞洲捕蟲草主要有這些特征：狀如水瓶，顏色鮮亮，有半掩的蓋子，綜合此三項(xiàng)可知，只有A項(xiàng)最合適。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(小樹)”【語篇解讀】 本文是科普閱讀。由于天氣變暖、疾病和海岸開發(fā)等原因，世界上大量的珊瑚礁在消失，特別是在印度洋、太平洋地區(qū)。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.解析細(xì)節(jié)理解題。從第三段可知，在澳大利亞的大堡礁、珊瑚礁也在消失，情況跟菲律賓的一樣糟糕。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解析推理判斷題。從文章第一段的介紹可知，珊瑚礁的消失與三個(gè)因素有關(guān)，而氣候變暖和海岸開發(fā)都有人為因素在里面。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.解析細(xì)節(jié)理解題。文章倒數(shù)第二段第一句說明，珊瑚礁為很多海洋動(dòng)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(樹干)grows bigger each year.Under its bark(樹皮)，a tree adds a layer of new wood each year it lives.If you look at a tree stump(樹樁)，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(美國黃松)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.【語篇解讀】 本文主要講了樹的年輪。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解析推理判斷題。由第三段第四、五、六句可知答案為A。答案A44A tree grows a new layer of wood_.Aeach week Bwhenever it rainsCevery year Devery season解析細(xì)節(jié)理解題。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解析推理判斷題。本文主要講述了樹的年輪和科學(xué)家對它的研究。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.解析推理判斷題。見全文最后一句。答案DDHidden in our subconsciousness(潛意識(shí)) 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(拼圖玩具) 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.【語篇解讀】 人生如旅行，重要的是旅行的過程和途中的風(fēng)景，而不是目的地。不要懊悔過去，也不要恐懼未來，要好好珍惜和享受現(xiàn)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.解析推理判斷題。在第一段，作者詳細(xì)描述了我們潛意識(shí)中在旅行途中看到的美景，但接下來兩段描述了現(xiàn)實(shí)生活中我們注重目的地的事實(shí)，由此可知作者描述這幅心靈圖像是為了將現(xiàn)實(shí)旅行與其對比。答案D48How do people feel when they're on their trip?APuzzled. BHappy. CRelaxed. DImpatient.解析推理判斷題。根據(jù)第二段“How restlessly we pace the aisles(通道).”可以了解人們經(jīng)過通道時(shí)的那種焦躁不安的情緒，故選D。puzzled“迷惑的”；happy“高興的”；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.解析句子理解題。根據(jù)倒數(shù)第二段中“It is the regret over yesterday and the fear of tomorrow”可知，對過去的懊悔和對未來的恐懼使得人們無法享受現(xiàn)在，故C項(xiàng)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.解析寫作意圖題。作者試圖告訴人們要樹立正確的人生觀，不要懊悔過去，也不要恐懼未來，要好好珍惜和享受現(xiàn)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.【語篇解讀】 本文是應(yīng)用文。文章介紹在海外旅行時(shí)，怎樣保護(hù)環(huán)境，選擇綠色活動(dòng)。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解析主旨大意題。第一段中“在海外旅行時(shí)，怎樣保護(hù)環(huán)境”Choices made about where to go，how to get there and what to do while there can either benefit or harm the environment是本文的主題句。答案B52The Souvenir Alert webpage gives you information about_.Asouvenirs availableBforbidden souvenirsCwhere to trade souvenirsDall types of products解析細(xì)節(jié)理解題。B項(xiàng)forbidden souvenirs與原文中“非法旅游紀(jì)念品”交易的含義最接近。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.解析細(xì)節(jié)理解題。從第一部分第二條Switchi
