 More about Alzheimer's Disease

Scientists have developed skin tests that may be used in the future to identify people with Alzheimer's diseasel and may ultimately allow physicians to predict 51 is at risk of getting this neurological disorder.

The only current means of 52 the disease in a living patient is a long and expensive series of tests that eliminate every other cause of dementia.

"Since Alois Alzheimer described the 53 nearly a century , people have been trying to find a way to 54 diagnose it in its early stages, " said Patricia Grady, acting director of the National Institute of Neurological Disorders and Stroke in Bethesda, Maryland. "This discovery, if 55 , could prove a big step forward in our efforts to deal with and understand the disease. "

Alzheimer's is the single greatest 56 of mental deterioration in older people, affecting between 2.5 million and 4 million people in the United States 57. The devastating disorder gradually destroys memory and the ability to function, and eventually causes death. There is currently no known 58 for the disease.

Researches 59 that the skin cells of Alzheimer's patients have defects that interfere with their ability to regulate the flow of potassium in and out of the cells. The fact that the cell defects are present in the skin suggests that Alzheimer's 60 from physiological changes throughout the body, and that dementia may be the first noticeable 61 of these changes as the defects affect the cells in the brain, scientists said.

The flow of potassium is especially critical in cells responsible for memory formation. The scientists also found two other defects that affect the cells' supply of calcium, another 62 element.

One test developed by researches calls 63 growing skin cells in a laboratory culture and then testing them with an electrical detector to determine if the microscopic tunnels that 64 the flow of potassium are open. Open potassium channels create a unique electrical signature.

A spokesman for the Alzheimer's Association said that if the validity of the diagnostic test can be proven it would be an important 65, but cautioned that other promising tests for Aizheimer's have been disappointing.

  答案與解析

51.D。本題考查關係代詞。題幹:科學家們發現,採用面板化驗的方法可以判斷病人是否患有老年痴呆症,並且最終有助於醫生預測__________有患上這種神經功能紊亂性疾病的危險。此處是“預測”的賓語從句,而該從句缺少主語,所以用who引導。因此該題答案為D。

52.D。本題考查語義線索。題幹:要 __________ 一個病人是否患有這類疾病,目前唯一的方法是進行一系列長期而昂貴的測試,以排除導致痴呆的其他病因。四個選項分別代入後,只有diagnose the disease(診斷疾病)比較符合語境,所以該題答案為D。

【考點延伸】fight for/against sth為……而戰/為反對……而戰

53.C。本題考查語義線索。題幹:自從艾洛伊斯•阿爾茨海默記載了這個__________以後,近一百年來人們一直在努力尋找能夠在早期階段就能__________診斷出這種疾病的方法……本文討論的早老性痴呆症,因而是記載了這個疾病以來,所以該題答案為C。

54.B。本題考查語義線索。題幹:自從艾洛伊斯•阿爾茨海默記載了這個疾病以後,近一百年來人們一直在努力尋找能夠在早期階段就能__________診斷出這種疾病的方法……四個選項分別代入,顯然是尋求精確診斷的方法,所以該題的答案為B。

55.C。本題考查語義線索。題幹:這個發現如果__________,將會意味著我們在治療和了解這種病症方面前進了一大步。上文提到近一百年來人們一直在努力尋找能夠精確診斷的方’法,所以一旦該發現得到證實,將使一大進步,所以該題的.答案為C。

56.A。本題考查語義線索。題幹:早老性痴呆是導致老年人大腦功能退化的唯一的重要。早老性痴呆與大腦退化有著直接的聯絡,而不僅僅只是影響因素,所以選擇reason比較符合語境

57.D。本題考查語義線索。題幹:早老性痴呆是導致老年人大腦功能退化的唯一的重要原因。在美國,就有約250萬到400萬人患有這種疾病。四個選項分別代入後,僅僅在美國比較符合邏輯,突出早老性痴呆的嚴重性,所以該題答案為D,其他三個都與語境不搭。

58.C。本題考查語義線索。題幹:目前,對這種病仍然沒有已知的。四個選項分別代入後,結合上下文可知是沒有已知的治療方法,所以該題答案為C,其他三個都與語境不搭。

59.A。本題考查語義線索。題幹:研究者早老性痴呆症患者的面板細胞有缺損,這種缺損會影響人體對出入於細胞的鉀的流量的調控。四個選項分別代入後,結合上下文可知研究者發現了早老性痴呆症患者的面板細胞有缺損的症狀,所以該題答案為A,其他三個都與語境不搭。

60.C。本題考查語義和固定搭配。題幹:科學家認為面板細胞有缺損這個事實表明,早老性痴呆人體全身的生理變化,並且大腦細胞受損帶來的變化所產生的最為明顯的就是痴呆。四個選項都可以跟後面的介詞from搭配,其中keep from意為“阻止,抑制”,break from意為“決裂,掙脫”,result from意為“起因於,由……造成”,translate…from…意為“從……翻譯為……”,但是語境是分析早老性痴呆的原因,所以result from比較符合語境,因而答案為C。

【考點延伸】resultin(導致);be causedby(由……引起);bring about(因此,產生)

61.A。此處考查語義線索。題幹:科學家認為面板細胞有缺損這個事實表明,早老性痴呆由人體全身的生理變化所引起,並且這種受損大腦細胞時,這種變化所產生的最為明顯的影響就是痴呆。四個選項分別代入後,此處就是分析受損細所帶來的影響,因此affect(影響)比較符合此處的語境,其他三個選項跟語境不搭。

62.D。這裡考查語義和並列結構。題幹:鉀的流量對於與記憶密切相關的細胞至關重要。科學家還發現還有兩種細胞的缺損會影響細胞中鈣的含量。鈣也是一種元素。從“also”可知前後的分句之間為並列關係,討論的是細胞的缺損會帶來鉀和鈣的流失,由此可知此處也應填入critical一詞,與上一句相照應。

63.c。此處是考查固定搭配。題幹:研究者進行的面板測試中有一種在實驗室環境中培養面板細胞。call與選項中的四個詞都可以組成固定搭配,其中call at意為“拜訪,訪問”,call out意為“喚起,大聲喊”,call for意為“要求”,call of意為“邀……同去”,但是隻有call for符合語境,所以該題答案為C。

【考點延伸】call off(取消,刪除);call up(召集)

64.D。此處考查語義線索。題幹:研究者進行的面板測試中有一種要求在實驗室環境中培養面板細胞,然後使用檢電器進行測試,檢查鉀量的極微小管道是否暢通。四個選項分別代入後,可知微小管道的主要功能就是來控制鉀量,因而該題的正確答案為D。

65.C。此處考查語義線索。題幹:早老性痴呆研究協會的一名發言人說,這種診斷性測試如果得到證實,將是一個重要的__________。根據語境,如果診斷性測試得到證實,就會給早老性痴呆的診治提供幫助,所以這是一個重要的進步,因此該題的答案為C。
