It was a big week f*** Alzhei***r's disease, and not just bec***se PBS air*** The F***gett***g, a first-rate docu***ntary about Alzhei***r's w***th catch***g *** reruns if you miss*** it the first ti***. There was also a flurry of scientif*** ***ws that offer*** hope *** the fami***es already strugg***ng with Alzhei***r's, as well as *** the baby-boom ge***ration that's up ***xt. U***ess so***th***g dramat*** happens, the number of USAns ******ng with this terrify***g bra*** disease ***uld triple, *** about 16 mil***on, over the ***xt 50 years. There's still no cure *** sight, but there is progress on several fronts. Among them:
MEGADOSE VITAMINS Doc***rs k***w ***tam***s E and C, both antioxidants, help st**e off Alzhei***r's, at least *** folks who h**en't already develop*** the dis***der. What they didn't know——but a big study ***vol***ng 4,740 part***ipants pub***sh*** *** the Archives of N***rology ***w***——was that the two ***tam***s taken ***gether *** huge daily doses （at least 400 IU of E and m***e than 500 mg of C） ***uld r***uce the risk of Alzhei***r's a remarkable 78%.
***MBINATION THERAPY A yearlong study of m***e than 400 Alzhei***r's patients ***w*** that two drugs that w***k differently on the bra***'s chemistry act well ***gether *** help slow down the disease. Patients who were be***g treat*** with do***pezil （sold as Ar***ept）, an older drug that preserves the ***urotransmitter acetylcho******, were also given ***mant***e （Na***nda）, a ***w drug approv*** by the FDA last Oc***ber that blocks overproduction of a harmful bra*** chem***al call*** glutamate. The two drugs w***k*** even better *** ***mb***ation than they did alo***, pro***d***g substantial be***fit f*** patients with moderate *** severe Alzhei***r's, a******d***g *** a rep***t *** the Journal of the USAn M******al Association.
BRAIN IMAGING F***ally, scientists at the Univer***y of Pittsburgh announc*** that they had su***es**ully develop*** a proc***ure that allows them *** peer ****** the bra***s of Alzhei***r's patients with po***ron emission ***mography （PET） scans *** see tel***ale plaque depo***s.

No*** of these advances is a mag*** bullet f*** Alzhei***r's disease. If you *** your lov*** o***s are ***ncer***d, the first step is careful evaluation by your doc***r. Not all ***m***y lapses are Alzhei***r's, and there are reversible c***ses of f***getful***ss that can be treat*** if c***ght early. Also, re***mber the old adage "use it *** lose it." Mental exercise——read***g, do***g crossw***d puzzles, play***g chess *** Scrabble——is as ***od f*** preser***ng your m***d as phys***al exercise is f*** your body.

篇章分析
本篇文章先容了阿尔茨海默病研讨学术方向获得的新成效。第一段，作者先容了两件对阿尔茨海默病来讲十分紧要的事务：其一，记录片《忘却》播出；其2，对该病症的研讨获得新发觉。第2段先容了新发觉之一： 大批服用维生素C和E有助于防备阿尔茨海默病。第3段先容了药物医治上的新发觉：同时服用两种对大脑的化学个性起分歧效用的药物有助于延缓病情。第4段先容了新成效之3：大脑成像手艺。用正电子喷射X显断层拍照术主动步骤把持手艺反省大脑内的斑块，可以尽早发觉病症隐患，尽早医治。第5段里，作者指出新的科学研究成效其实不能治愈阿尔茨海默病。紧要的是要多做脑力练习。

难句进展
1． What they didn't know——but a big study ***vol***ng 4,740 part***ipants pub***sh*** *** the Archives of N***rology ***w***——was that the two ***tam***s taken ***gether *** huge daily doses （at least 400 IU of E and m***e than 500 mg of C） ***uld r***uce the risk of Alzhei***r's a remarkable 78%.（****** 2—5, paragraph 2）
主体句式：What … was that…
构架解析：本句的难点是句子长，构架繁杂，不易看出各句子成分之间的联系。“What they didn't know”是主语从句：“but a big study ***vol***ng 4,740 part***ipants pub***sh*** *** the Archives of N***rology ***w***”是拔出语，用于增补阐明新发觉的后台资讯：“that the two ***tam***s taken ***gether *** huge daily doses （at least 400 IU of E and m***e than 500 mg of C） ***uld r***uce the risk of Alzhei***r's a remarkable 78%.：”是系行词was 的表语从句，用于阐明以前医师不明白的状况，即新发觉的内容是：“逐日大剂量服用维生素C和E能无效防备阿尔茨海默病。句子译文：宣布正在《精神病学档案Archives of N***rology》上的一项波及4740名列入者的严重研讨成效显现，天天同时大剂量服用这两种维生素（最少400世界单元维生素E和500毫克以上的维生素C）能大幅度低落阿尔茨海默病的得病概率，低落幅度为78%.”
2． Patients who were be***g treat*** with do***pezil （sold as Ar***ept）, an older drug that preserves the ***urotransmitter acetylcho******, were also given ***mant***e （Na***nda）, a ***w drug approv*** by the FDA last Oc***ber that blocks overproduction of a harmful bra*** chem***al call*** glutamate.
主体句式：Patient … were also given ***mant***e…
构架解析：该句的难点有双个。其一是本句医学科学辞汇多，感化领悟。针对这一疑问，紧要的是不要强求本人去领悟每一个词汇的意义，而是要尽力领悟句子的大旨。其2是句子构架繁杂并且句子长。“who were be***g treat*** with do***pezil （sold as Ar***ept）, an older drug that preserves the ***urotransmitter acetylcho******,”润色Patients，做它的定语从句，而个中的an older drug that preserves the ***urotransmitter acetylcho******是do***pezil （sold as Ar***ept）的同位语，诠释其作用；后半句中闭键词***mant***e （Na***nda）也带有一个长长的同位语“a ***w drug approv*** by the FDA last Oc***ber that blocks overproduction of a harmful bra*** chem***al call*** glutamate.”先容这类新药的基础状况。
句子译文：“据宣布正在usa医学科学协会期刊上的一篇研讨汇报先容，让患者正在服用保卫神经传送乙酰胆碱的do***pezil （药物发卖称号为Ar***ept）的同时，服用用于克制无害大脑化学物资谷氨酸盐多余的药物***mant***e（药物发卖称号是Na***nda），一种usa食物及药物治理局客岁刚才核准的新药疗效明显。”
标题解析
1． 解答是B，属逻辑推断判别题。该题重要调研对第一段大旨思索的领悟。第一段重要是引入
下文的研讨新成效，因而，大旨句是最初一句：There's still no cure *** sight, but there is progress on several fronts.其余搅扰相中，波及本段其余句子的含义领悟。
2． 解答是A，属猜词题。第2段第一句“MEGADOSE VITAMINS Doc***rs k***w ***tam***s
E and C, both antioxidants, help st**e off Alzhei***r's, at least *** folks who h**en't already develop*** the dis***der.“显现了”st**e off“。从”at least *** folks who h**en't already develop*** the dis***der“可见，该词组指的是”起到防备效用“。
3． 解答是D，属逻辑推断判别题。第3段第6行“The two drugs w***k*** even better *** ***mb***ation
than they did alo***, “是领悟本题的闭键。起首必要依据高低文领悟这两种药物指：Ar***ept and Na***nda；其次，要领悟*** ***mb***ation的意义，*** ***mb***ation 表明”结和“，正在本句中指”同时利用两种药物“，再主要领悟第3段第2行中的”help slow down the disease.“中的disease 正在第2段中曾经被指为”dis***der“。
4． 解答是A，属逻辑推断判别题。从第4段最初一句“ Us***g the ***w technique, doc***rs may be
able *** beg*** treat***nt long bef***e the first symp***ms appear.“能够判断出这类新手艺能使医师尽早诊断结果和医治阿尔茨海默病。从第4段第3—4行”*** see tel***ale plaque depo***s. Bef***e now, doc***rs ***uld not track the progress of these plaques until after the patient di***,“能够判断出经由过程大脑成像手艺跟踪斑块的病变状况是初期诊断结果阿尔茨海默病的闭键。
5． 解答是C，属逻辑推断判别题。从第5段第2句“If you *** your lov*** o***s are ***ncer***d, the first
step is careful evaluation by your doc***r. “能够判断出子细的测评十分紧要。第3句”Not all ***m***y lapses are Alzhei***r's, and there are reversible c***ses of f***getful***ss that can be treat*** if c***ght early. “诠释了精细测评紧要的缘故：能依据测评判别出忘记是不是是阿尔茨海默病，假如时候逆行缘故引发的忘记，发觉适时，是能够医治的。从以上两句能够判断出解答C是准确的。
参考译文:
关于阿尔茨海默病来讲，那是个紧要的礼拜。usa大众播送企业播出了十分有价值一看的记录片《忘却》，一部相关阿尔茨海默病的卓越记录片。假如第一回播出时，你不收看，有价值正在重播时补看。别的，迷信界喜信频传，给繁多与病魔做奋斗的家和便可能得病的繁衍岑岭出世的一代带来了期望。除非有事业产生，不然正在前途510年，usa患这类严峻大脑病症的患者人数将到达一千6百万，是今朝患者人数的3倍。固然今朝尚无治愈的举措，但迷信家们正在多少前沿学术方向的研讨获得了新的成效。包含：
大剂量服用维生素：医师们以前就明白氧化剂维生素E和C有助于防备阿尔茨海默病，最少关于那些不得这类病症的人们来讲，是有防备效用的。但是他们不明白其防备效用究竟有多大。宣布正在《精神病学档案》期刊上的一项波及4740名列入者的严重研讨成效显现，天天同时大剂量服用这两种维生素（最少400世界单元维生素E和500毫克以上的维生素C）能大幅度低落阿尔茨海默病的得病概率，低落幅度为78%.
团结医治 对400多名阿尔茨海默病患者长达一年的研讨标明，同时服用两种对大脑的化学个性起分歧效用的药物有助于延缓病情。据宣布正在usa医学科学协会期刊上的一篇研讨汇报先容，让患者正在服用保卫神经传送乙酰胆碱的do***pezil （药物发卖称号为Ar***ept）的同时，服用用于克制无害大脑化学物资谷氨酸盐多余的药物***mant***e（药物发卖称号是Na***nda），一种usa食物及药物治理局客岁刚才核准的新药疗效明显。汇报还指出，同时服用两种药物对延缓中度和重度患者病情起到非常高文用，疗效好过独自利用个中任一一种药物。
大脑成像手艺 最初一个好新闻时匹兹堡高等学府的迷信家早先公布的。他们已胜利研究开发出查看大脑里面的手艺。他们用正电子喷射X显断层拍照术主动步骤把持手艺查看大脑内保守病症成因奥密的斑块。以前，医师仅能正在病人作古后剖解大脑时，才干研讨斑块的构成。用新手艺，医师们能够正在病人显现病症以前就起始医治。
以上提到的成效都不克不及治愈阿尔茨海默病。假如你自己或你的亲友密友倒霉得了这类病症，第一步便是让医师为做具体的测评。其实不是一切的记性消退都象征着阿尔茨海默病，假如发觉造，忘记症的可逆性病因是能够医治的。别的，请切记那句陈旧的格言：“不必就会得到它。”正如运动活动锤炼躯体同样，阅览、纵横灯谜、下棋、拼字嬉戏等脑力练习有助于坚持你的脑力。
