15、 D．a(chǎn)voided 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　B 17．A.resulted B．brought C．lay D．came 解析　lie in在于。語境為“他們認為答案在于他們之間產(chǎn)生的愛”。 答案　C 18．A.little B．much C．favor D．few 解析　根據(jù)句意可知，在大風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　

16、A 19．A.But B．Still C．Though D．Otherwise 解析　Ole仍然每次都鼓勵著Trufa。still“仍然，還”。but表示轉折，though表示讓步，otherwise“否則”均不符合語境。 答案　A 20．A.complain B．say C．request D．a(chǎn)nnounce 解析　根據(jù)上下文可知，這里是說“在寒冷的暴風雨的夜晚，Ole就會跟Trufa說……”。 答案　B 21．A.regretful B．senseless C．different D．happy 解析　沒

17、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　B 22．A.expected B．intended C．feared D．imagined 解析　下文中提到一陣風吹來，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，設想”。 答案　C 23．A.open B．a(chǎn)ctive C．loose D．a(chǎn)live 解析　從

18、下文的“Soon Ole disappeared from sight”可知Ole被風從樹上吹下來了。loose符合語境。 答案　C 24．A.appreciate B．win C．a(chǎn)fford D．bear 解析　兩片賴以生存的葉子中的一片被風吹掉了，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　D 25．A.stepped into B．caught in C．took in D．sank into 解析　上文提到Trufa白天強忍悲痛，到了晚上變得非常絕望，故選sink into “漸漸進入(

19、消極、不快等)狀態(tài)”。 答案　D 26．A.fortunes B．changes C．misfortunes D．chances 解析　她感到落葉的不幸遭遇應該歸咎于大樹。misfortune“不幸”，此處指的是被大風吹落的不幸遭遇。fortune“幸運，運氣”，change“改變”；chance“機會，機遇”。 答案　C 27．A.firmly B．slightly C．deeply D．tightly 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“堅定地，穩(wěn)固地”；sligh

20、tly“輕微地，稍微”；deeply“深深地”；tightly“緊緊地”。 答案　A 28．A.upset B．blow C．touch D．make 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　A 29．A.delight B．a(chǎn)mazement C．disappointment D．satisfaction 解析　從下文提到的“The wind had blown her

21、 down”，可知Trufa已經(jīng)被風吹掉了，當她發(fā)現(xiàn)時肯定是驚訝的，故用amazement“驚愕，驚異”。delight“高興，欣喜”；disappointment“失望”； satisfaction“滿足，滿意”。 答案　B 30．A.hanging B．staying C．leaving D．sticking 解析　Trufa已經(jīng)被風吹到了樹下，因此她已經(jīng)不在樹上了。hang懸掛，符合題意。 答案　A 31．A.spoke B．remembered C．considered D．knew 解析　本句說的是Trufa當時心里

22、的想法，因此know“知道”符合題意。 答案　D 32．A.decided on B．held on C．concentrated on D．depended on 解析　語意為“她不僅僅是一片依靠風的葉子而是宇宙的一部分”。 答案　D 33．A.some B．a(chǎn)ny C．part D．one 解析　part of“……的一部分”，意思為“她是宇宙的一部分”。 答案　C 34．A.presented B．treated C．provided D．greeted 解析　Ole與Trufa都從樹上被吹落下來，他們見面之后當然要

23、相互問候了，故選greet。 答案　D 35．A.pure B．brief C．permanent D．free 解析　與宇宙一樣的愛當然是強大的和持久的，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，從每題所給的四個選項(A、B、C和D)中，選出最佳選項。 A If you travel to a new exhibit at the San Francisco Conservatory of Flowers，you will have chances to see some meat

24、­eating 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 en

25、zymes(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 develop

26、ed 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 cont

27、ainer 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

28、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

29、 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——靠捕食動物獲得生長所需養(yǎng)分的“食肉植物”。 36．From the first paragraph，we can know that bladderworts can________. A．capture 50 small insects in a second B．capture an insect in the shortest

30、time C．be found floating on a quiet lake D．digest an insect in 1/50 of a second 解析　細節(jié)理解題。第一段指出，bladderworts能在1/50秒的時間內捕獲一只小昆蟲，是植物中已知的捕獲動物速度最快的，因此選B。 答案　B 37．If the trap door of a meat­eating plant is closed，the plant________. A．is fooling insects into taking a sip B．is producing ne

31、ctar C．is tempting insects to come close D．is enjoying a dinner 解析　細節(jié)理解題。第二段說，一旦“陷阱門”將獵物關起來，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　D 38．Meat­eating plants can grow in wet and poor soil because they________. A．can get nutrition from animals B．don't need much food value C．can make

32、the most of such conditions D．have 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物中獲取養(yǎng)分，而不是從土壤中獲取養(yǎng)分。 答案　A 39．Which 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，綜合此三項可知，只有A

33、項最合適。 答案　A B Researchers 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 Polynesia—dropped 20 percent in the past two decades. About 600 square miles of reefs have dis

34、appeared 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 thoug

35、ht，”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，fo

36、und 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 pro

37、vide 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 t

38、heir 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)。 40．What do we know about Great Barri

39、er Reef from the passage? A．It is well­protected and in much better condition than elsewhere. B．It also suffers a bad coral loss though it is well­protected. C．Because it is well­protected，reefs have never disappeared. D．It is as badly managed as the marine reserves in the Phi

42、 shelter for island residents. 解析　細節(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植物提供了“家”。 答案　A C How 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 e

43、ach 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 di

44、fferent 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

45、 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。 43．We could in

49、推理判斷題。見全文最后一句。 答案　D D Hidden in our subconsciousness(潛意識) 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 fe

50、eding 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

51、 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 loitering—waiting，waiting，waiting for the stat

52、ion. “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 m

53、ust 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

54、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 wi

55、ll 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。 47．Why does the author describe the mental picture? A．To lead us into a perfect world. B．To let people enjoy the scenery. C．To introduce an actual trip of his. D．To compare it to our life's journey. 解

56、析　推理判斷題。在第一段，作者詳細描述了我們潛意識中在旅行途中看到的美景，但接下來兩段描述了現(xiàn)實生活中我們注重目的地的事實，由此可知作者描述這幅心靈圖像是為了將現(xiàn)實旅行與其對比。 答案　D 48．How do people feel when they're on their trip? A．Puzzled. B．Happy. C．Relaxed. D．Impatient. 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)過通道時的那種焦躁不安的情緒，故選D。puzzled“迷惑的”

57、；happy“高興的”；relaxed“放松的”。 答案　D 49．What does the author mean by “Regret and fear are twin thieves who rob us of today” in Paragraph 5? A．Regret and fear are responsible for the loss of today. B．We must be careful of the two thieves：regret and fear. C．Regret and fear stop us from enjoying our

58、present life. D．We'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項最佳。 答案　C 50．Why does the author write the passage? A．To teach us a good lesson. B．To tell us the right attit

59、ude to life. C．To advise us to forget our worries. D．To 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　B E UK residents take over 40m holidays abroad and more than 100m overnight stays in this country each year.Choices made about where to go，ho
