Text 4 There have been rumors. There‘s been gossip. All Hollywood is shocked to learn that Calista Flockhart, star of Fox’s hit TV show Ally McBeal, is so thin. And we in the media are falling all over ourselves trying to figure out whether Flockhart has an eating disorder, especially now that she has denied it. Well, I‘m not playing the game. If the entertainment industry really cared about sending the wrong message on body image, it wouldn’t need so many slender celebrities in the first place. But the fact remains that 2 million Americans—most of them women and girls—do suffer from eating disorders. In the most extreme cases they literally starve themselves to death. And those who survive are at greater risk of developing brittle bones, life-threatening infections, kidney damage and heart problems. Fortunately, doctors have learned a lot over the past decade about what causes eating disorders and how to treat them. The numbers are shocking. Approximately 1 in 150 teenage girls in the U. S. falls victim to anorexia nervosa, broadly defined as the refusal to eat enough to maintain even a minimal body weight. Not so clear is how many more suffer from bulimia, in which they binge on food, eating perhaps two or three days‘ worth of meals in 30 minutes, then remove the excess by taking medicine to move the bowels or inducing vomiting. Nor does age necessarily protect you. Anorexia has been diagnosed in girls as young as eight. Most deaths from the condition occur in women over 45. Doctors used to think eating disorders were purely psychological. Now they realize there’s some problematic biology as well. In a study published in the Archives of General Psychiatry recently, researchers found abnormal levels of serotonin, a neurotransmitter in the brain, in women who had been free of bulimia for at least a year. That may help explain why drugs have allowed a lot of people to stop swallowing in large doses of food. Unfortunately, the pills don‘t work as well for denial of food. Nor do they offer a simple one-stop cure. Health-care workers must re-educate their patients in how to eat and think about food. How can you tell if someone you love has an eating disorder? “Bulimics will often leave evidence around as if they want to get caught.” Says Tamara Pryor, director of an eating-disorders clinic at the University of Kansas in Wichita. Anorexics, by contrast, are more likely to go through long periods of denial. 1. We can infer from the first paragraph that _____.[A] the media has mislead the public’s view of celebrities[B] there is much misunderstanding about eating disorders[C] body image concerns are an indication of eating disorders[D] the entertainment industry is combating eating disorders 2. The victims of eating disorders, more often than not, will _____.[A] starve themselves to death[B] suffer greatly from the complications[C] puzzle doctors in the years to come[D] recover completely with no aftereffects 3. The word “binge” (Line 3, Paragraph 3) most probably means _____.[A] eat excessively [B] refuse to eat[C] fail to digest [D] enjoy a good appetite 4. Bulimia is found to be _____.[A] related to the level, of serotonin[B] psychological rather than biological[C] identical with anorexia nervosa in the cure[D] a leading cause of death among middle-aged women 5. The way to find a person with eating disorders _____.[A] focuses on hidden symptoms[B] varies with type of the condition[C] is oriented at the victim‘s response[D] remains perplexing despite efforts made

答案1.C 2.B 3.A 4.A 5.B

总体分析本文主要介绍了两种饮食性疾患。

第一段:以一位明星的事例引出全文讨论的话题——饮食性疾患。

第二段至五段:介绍两种饮食性疾患(厌食症和暴食症)的危害、表现、治疗及判断方法。

试题精解1.从第一段我们可以推知_______.[A] 媒体误导了公众对名人的看法[B] 有很多关于饮食性疾患的误解[C] 对身体形象的关注是饮食性疾患的标志[D] 娱乐业正在对抗饮食性疾患[精解] 本题考查推理引申。第一段举了一位明星的例子,指出由于她过分消瘦,引起公众怀疑她患有饮食性疾患。由此可推出公众的怀疑是因为该明星对身体形象的过分关注,[C]项正确。该段末句用虚拟语气指出,“如果娱乐业真地担心在身体形象上传达错误的信息……”。言外之意是娱乐业在一定程度上误导了人们有关身体形象的看法。排除 [D]项,[A]项错在celebrity.[B]项无从推知,文章开始出现的rumors和gossip指的是公众对明星是否患病的猜测。

2.饮食性疾患的受害者经常会_____.[A] 把自己饿死 [B] 因并发症而备受痛苦[C] 在将来使医生感到迷惑 [D] 完全康复不留后遗症[精解] 本题考查事实细节。第二段主要论述了饮食性疾患的危害及治疗情况。由第三句可知,饮食性疾患的幸存者,患各种其他疾病的危险更大。[B]项正确,排除[D]项。由第二句中in the most extreme cases排除[A]项;由末句可知,医生已经掌握了大量关于饮食性疾患的信息,排除[C]项。

3.第三段第三行的单词“binge”可能的含义是_____.[A] 过量地吃 [B] 拒绝吃 [C] 消化不良 [D] 胃口很好[精解] 本题考查词义。该词语上文suffer from bulimia暗示它是一种疾病,下文对该词作出了进一步解释:三十分钟内吃掉两三天的饭量。因此[A]项正确。

4.暴食症被发现_____.[A] 和复合胺水平有关 [B] 是心理而非生理问题[C] 在治疗方法上和厌食症一样 [D] 是中年妇女死亡的主要原因[精解] 本题考查事实细节。由第四段第三句和第四句可知,研究发现复合胺有助于让许多人停止吞食大量的食物,即摆脱暴食症。因此[A]项正确。第三段首句指出,饮食性疾患(包括暴食症)也是生理问题,排除[B]项。第四段第五句指出,(治疗暴食症的)药物对于治疗厌食不起作用。排除[C]项。 [D]项文中未涉及,第三段末句提到,厌食症造成的死亡大多发生在45岁以上的妇女身上。

5.发现饮食性疾病患者的方式_____.[A] 集中在不明显的症状上 [B] 因患病类型而不同[C] 是针对病人的反应的 [D] 尽管作出了努力还是令人困惑[精解] 本题考查事实细节。第五段指出,暴食症常常会留下证据,而厌食症则更可能会长期地否认。因此[B]项正确。

核心词汇与超纲词汇(1)fall all over oneself 特别卖力,不遗余力(2)literally(ad.)照字面意义地;真正,完全;差不多,简直(3)fall victim(to sth.)受伤,受损,被害,如Many plants have fallen victim to the sudden frost(许多植物因突如其来的霜降冻伤了)。

(4)binge(n./v.)狂欢作乐,大吃大喝;~ on sth.,如She binges on chocalate when she‘s depressed(心情不好时她就使劲吃巧克力)。

(5)bowel(n.)肠,empty/move/open the ~s(排便);内部,the ~s of sth.内部最深处(6)induce(v.)劝诱,促使,导致,引起(7)vomit(n./v.)呕吐(物)

(8)problematic(a.)问题的,有疑问的(9)denial(n.)否认,否定;拒绝

全文翻译

一直有谣言。一直有闲言碎语。得知福克斯热门电视剧《甜心俏佳人》中的明星卡莉斯塔。弗洛克哈特如此瘦弱,整个好莱坞都很震惊。而我们在媒体中尽力弄清楚弗洛克哈特是否有饮食性疾患,特别是现在她自己对此予以否认。好吧,我不是在兜圈子。如果娱乐业真地担心在身体形象上传达错误的信息,那么首先就不需要这么多身材纤细的名人。

但是事实仍然是,两百万美国人,尤其是妇女和女孩确实有饮食性疾患。在最极端的情形下,她们真地把自己饿死。而那些幸存者出现骨质疏松、威胁生命的传染病、肾损伤和心脏问题的危险更大。幸运的是,过去十年中医生就造成饮食性疾患的原因和治疗方法已经获悉了大量信息。

数字是惊人的。几乎150个青春期的女孩中就有一个成为厌食症的受害者。厌食症广义上被定义为有意节食以维持最小的体重。不清楚还有多少人患有暴食症,这些人狂吃,三十分钟内可能要吃掉两三天的饭量,然后通过吃药帮助大便通畅或者催吐的方式来去处多余的食物。年龄也不一定可以保护你。连八岁的小女孩也被诊断患有厌食症。这种疾病造成的死亡大多发生在45岁以上的妇女身上。

医生过去认为饮食性疾患只是心理上的问题,但现在他们意识到也有一些生理上的问题。最近在《普通精神病学纪要》发表的研究中,研究者在摆脱暴食症至少一年的妇女中发现非正常水平的复合胺(一种大脑中的神经传递素)。这也许有助于解释为什么药物让许多人停止吞食大量的食物。不幸的是,这些药物对于治疗厌食不起作用。而且它们也不提供简单的一次性治疗。医护工作者必须在如何饮食及如何看待食物方面重新教育他们的病人。

怎样判断你所爱的人患有饮食性疾患呢?威奇塔州堪萨斯大学饮食性疾患门诊部主任塔玛拉。派亚说,“暴食症常常会留下证据就好像他们想被抓获一样”。相反,厌食症则更可能会长期地予以否认。

Part B Directions:In the following article, some sentences have been removed. For Questions 41-45, choose the most suitable one from the lish A-G to fit into each of the numbered blank. There are two extra choices that do not fit in any of the gaps. Mark your answers on ANSWER SHEET 1. (10 points)

Rain forest structure is distinct from most other forest types because of its many layers of vegetation, referred to as strata. The lowest stratum is the understory, composed of palms, herbaceous plants (such as wild ginger), and tree seedlings and saplings. (41) _____________. Many have deep red coloring on the underside of their leaves to capture some of the scarce light that does manage to reach the forest understory. This red coloring enables understory plants to absorb light of different wavelengths than do the plants with rich, green-foliaged canopy, the umbrella-shaped upper structure of trees. Above the forest floor but below the canopy are one or more midstory strata, made up of woody plants, such as large shrubs and midsized trees. The overstory is the canopy, in which the tree crowns form a continuous layer that captures the major part of the rainwater and sunlight hitting the forest. The height of the canopy varies from region to region and forest to forest, ranging from 20 to 50 m (65 to 165 ft)。 (42) ____________. Researchers use hot air balloons, cables, catwalks, towers, sophisticated tree-climbing gear, and even robots to study the millions of plants and animals that make their home high up in the forest canopy. Canopy researchers also use huge cranes that are dropped into the heart of the forest by helicopters. Suspended from the crane‘s long, movable arm is a large cabin that functions as a mobile treetop laboratory. Moving from tree to tree, forest researchers collect specimens, conduct experiments, and observe life in the canopy frontier. The highest stratum of the rain forest is made up of the emergent trees, those individuals that stick up above the forest canopy. Emergents, which do not form a continuous layer, are usually the giants of the forest, reaching heights of 35 to 70 m (115 to 230 ft) or more, and trunk sizes of over 2 m (6.6 ft) in diameter. (43) _____________. However, these trees tend to be so large that they collectively account for the vast majority of the woody mass, or biomass, of the forest. The nicely ordered strata of the rain forest, including the continuous layer of the canopy, are regularly disturbed by naturally occurring events, such as falling trees. Trees in a rain forest canopy are often interconnected by vines, and a falling tree may pull as well as push other trees down with it, producing a domino effect of falling trees. The resulting opening in the forest canopy enables light to pour onto the forest floor. (44) _________________. Other natural disturbances create even larger openings in the forest canopies. For example, along the hurricane belt in the Caribbean and the typhoon belt along the western Pacific, some forests are substantially altered when high winds and storms blow down hundreds of trees every few decades. (45) _________________. Scientists have found that these natural disturbances and the subsequent forest regeneration are a vital process that leads to healthy and diverse forests.[A] New plants and animals then move into the area and begin to grow.[B] Just 2 percent of the sunlight goes through the many layers of leaves and branches above, so understory plant species have developed special traits to cope with low light levels.[C] On a smaller scale, large mammals, such as elephants, regularly destroy rain forest vegetation in the Congo River Basin in Africa.[D] An understory of shorter trees and a lacework of woody vines, or lianas, produce a forest of such complex internal architecture that many animals, including some sizable ones, rarely or never descend to the ground.[E] Less than one percent of the trees in the forest reside in the canopy and emergent layers.[F] Because more light penetrates the canopy, however, the vegetation of the understory and forest floor is better developed than in the tropics.[G] The rich, green canopy is teeming with life, and forest researchers have developed ingenious methods for accessing this mysterious ecosystem.

答案41.B 42.G 43.E 44.A 45.C

总体分析本文是一篇介绍热带雨林植被的科普性文章。

第一段:介绍下层植被的构成与特点以及中层植被的构成。

第二段:介绍最上层的新生树木层的特点。

第三、四段:分析指出自然干扰因素对森林的影响。

[A] 新的动植物会搬到这些地方并开始生长。

[B] 下层植被形成了适应低光强的特性。

[C] 有些大的哺乳动物通常会破坏非洲刚果河盆地的热带雨林植被。

[D] 下层植被和藤蔓植物形成了具有相当复杂的内部体系的森林。

[E] 生长在冠层和新生树木层的树较少。

[F] 由于阳光穿透冠层使下层植被和森林地表植被生长得更好。

[G] 研究者已经找到了评估森林冠层的独创的方法。

试题精解41.[精解] 本题考查的知识点是:段落内一致性原则+上下文的衔接本题空格出现在第一段中。上文提到热带雨林结构中的最低层是下层植被。下文提到,下层植被的植物叶子呈深红色,从而能够获取到达下层植被的少量的光。由此可见,上下文都围绕“下层植被”展开论述。出现关键词“understory”的选项有[B]、[D]和[F]。但是,[D]出现了上下文没有的新信息:“藤蔓植物”。[F]中出现了“冠层(canopy)”,但从下文即第一段倒数第二句对canopy一词的定义可知,它应在下文中第一次出现。由此排除[D]和[F]项。[B]强调下层植被适应低光强的特性,其中“低光强”与下文“获取少量的光”、“吸收不同波长的光”等内容相呼应。

42.[精解] 本题考查的知识点是:段落内一致性原则+上下文的衔接本题空格出现在第二段中。上文介绍了冠层的功能与高度。下文的内容可概括为:研究人员使用各种各样的手段对冠层进行研究。由此可见,上下文都围绕“冠层”展开论述。出现了关键词“canopy”的选项是[E]、[F]和[G]。[E]中出现了上下文没有的新信息:“新生树木层”,破坏了段落的一致性,该信息实际上到第三段第二句才首次出现。[F]中出现了逻辑词however,但从内容上看,上文与[F]项并不构成转折关系。而且[F]强调的是冠层与下层植被和森林地表植被的关系,与下文也无法衔接。[G]只涉及“冠层”和“研究者”的内容,与上下文都实现了很好的衔接。

43.[精解] 本题考查的知识点是:上下文的衔接+词语的呼应本题空格出现在第三段中。上文介绍了在热带雨林最上层的新生树木的特点。下文只有一句话,其中出现了表转折的逻辑词however和代词these trees.从文章结构看,第一至三段已经依次介绍了热带雨林的下层、中层、冠层和最上层,因此本题空格处不应该再回过去只谈论下层或冠层。与上文内容能很好衔接的只有[E],它直接提到了“新生树木层”;而且它的内容与下文也能构成转折,即,虽然树较少,但是都很粗壮。

44.[精解] 本题考查的知识点是:上下文的衔接本题空格出现在第四段末。上文介绍了雨林中连续的的树层可能遭到的破坏及影响。下文即第五段首句提到,其他的自然干扰会造成冠层更大的空隙。由此可知,上下文论述的是自然干扰对树层的影响。根据段落一致原则,空格处应延续上文的内容。[A]和上文能够衔接,其中the area指代上文中the forest floor.[C]有一定的干扰性,其中destroy一词与上文disturb呼应,但是从内容看,“非洲刚果河盆地的热带雨林植被”无法与上文“连续的树层”衔接。[D]虽然重现了上文的词语vines,但其内容与上下文毫无关联。[F]干扰性最大,其中从句“由于更多的阳光穿透森林冠层”与上文衔接非常紧密,但是主句内容与上下文都无法衔接,而且出现了新信息“in the tropics”。

45.[精解] 本题考查的知识点是:段落内一致性原则+上下文的衔接本题空格出现在第五段中。上文提到对森林造成影响的自然干扰因素并举例说明。下文指出科学家发现自然干扰因素对森林的形成很关键。由此可知,整个第五段围绕“自然干扰因素对森林的影响”展开论述。符合这一主题的只有[C],它衔接上文,继续举例说明自然干扰因素对森林的影响。

核心词汇或超纲词汇(1)strata(n.)(stratum的复数形式)层,岩层,地层,社会阶层(2)understory(n.)(=underwood)林下叶层,下层植物(3)foliaged(a.)叶饰的,有很多叶子的(4)canopy(n.)天篷,遮篷,苍穹(5)emergent(a.)新兴的,处于发展初期的 emerge(v.)出现(6)vines (n.) 藤,蔓(7)domino (n.)骨牌,多米诺骨牌(8)regeneration (n.)再生,重建

全文翻译热带雨林的结构有别于其它大部分森林类型,原因就在于它有很多的植被层,称之为树层。最低层是下层植被,由棕榈树、草本植物(如野姜花)、树苗和小树构成。仅有2%的阳光可以透过上面众多的叶层和枝层,所以下层植被形成了适应低光强的特性。[B] 许多植物的叶子下侧呈深红色,以便获取能够到达森林下层植被的少量的光。这种红颜色使下层植被比起那些有很多绿色叶子组成的冠层(即,树的伞状上层结构)的植被更能吸收不同波长的光。在森林地表以上冠层以下是一个或多个中间层,由灌木丛和中等大小的树木等木本植物组成。

冠层就是森林的上层,其中树冠形成连续不断的层面并获取到达森林的大部分雨水和阳光。冠层的高度因地区和森林的不同而不同,范围在20-50米(65-105英尺)之间。这个浓郁的绿色森林冠层焕发着勃勃生机,森林研究者已经找到了评估这个神秘的生态系统的一些独创的方法。[G] 研究人员使用热气球、电缆、狭窄过道、铁塔、精密的爬树设备,甚至使用机器人来研究数百万种把巢筑在高高的冠层上的动植物。冠层研究者们还使用大型的起重机,通过直升飞机将它们安置在森林的中心地带。悬挂在起重机长长的活动臂上的是一个较大的屋子,作为一个移动的树冠实验室使用。通过在树与树之间移动,研究者们收集样本、进行实验并且在冠层最边缘处观察生命。

热带雨林的最上层由新生的树木组成,那些独立的树在冠层上部竖起。这些新生的树木没有形成一个连续层,但它们通常是森林的“巨人”,高度可达35-70米(115-230英尺)或者更高,树干的直径也有两米多(6.6英尺)。但是,森林中不到1%的树生长在冠层和新生树木层。[E] 尽管如此,这些树一般都很粗壮,因此构成了森林中大部分的树木或生物物质。

雨林中排列有序的树层,包括连续的树冠层,经常遭到诸如树木倒塌这样的自然事件的破坏。雨林冠层的树木通常由藤蔓彼此相连,因此倒下的树木可能把其他的树都拽起和推倒,造成了一种树木倒塌的“多米诺”效应。结果,森林冠层出现的缺口使阳光能够照射到森林地表上来。然后,新的动植物会搬到这些地方并开始生长。[A]其他的自然干扰造成了森林冠层更大的空隙。例如,沿加勒比海飓风带和沿西太平洋的台风带,每几十年狂风和暴雨就会摧毁成百计的树木,因此一些森林就完全地改变了。在小范围内,一些大的哺乳动物,如大象,通常会破坏非洲刚果河盆地的热带雨林植被。[C]科学家已经发现这些自然干扰和后来的森林再生是一个至关重要的过程,这个过程形成了茂盛的、形形色色的森林。
