47、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 37．A.resulted B．brought C．lay D．came 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　C 38．A.little B．much C．favor D．few 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　A 39．A.But

48、 B．Still C．Though D．Otherwise 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　A 40．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(fēng)雨的夜晚，Ole就會(huì)跟Trufa說……”。 答案　B 41．A.regretful B．senseless C．different D．happy 解析　沒有你，“我”的生命就沒

49、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 42．A.expected B．intended C．feared D．imagined 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　C 43．A.open B．a(chǎn)ctive C．loose D．a(chǎn)live 解析　從下文的“Soon Ol

51、nes B．changes C．misfortunes D．chances 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　C 47．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(jiān)定地，穩(wěn)固地”；slightly“輕微地，稍微”；deeply“深深地”；tightly“緊緊地”。 答案　A 48．A.u

52、pset 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(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　A 49．A.delight B．a(chǎn)mazement C．disappointment D．satisfaction 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”；disa

53、ppointment“失望”； satisfaction“滿足，滿意”。 答案　B 50．A.hanging B．staying C．leaving D．sticking 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　A 51．A.spoke B．remembered C．considered D．knew 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　D 52．A.decided on B．held on C．concentrated on D．depended on

54、 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　D 53．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 54．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(dāng)然要相互問候了，故選greet。 答案　D 55．A.pure B．brief C．permanent D．

A．capture 50 small insects in a second B．capture an insect in the shortest time C．be found floating on a quiet lake D．digest an insect in 1/50 of a second 解析　細(xì)節(jié)理解題。

62、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　B 57．If the trap door of a meateating plant is closed，the plant________.

A．can get nutrition from animals B．dont need much food value C．can make 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(jìn)化中，它們演化出了捕獲昆蟲的“

64、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　A 59．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(xiàng)可知，只有A項(xiàng)最合適。 答案　A B Researchers from the University of North Carolina in Chapel Hill found that coral coverage in the IndoPaci
