Chronic kidney disease， or CKD， is a quiet epidemic， many of the 19 million Americans estimated to have it don’t know they do. The kidneys lose their ability to filter waste out of the bloodstream so slowly that symptoms aren’t obvious until the organs are very damaged.(第3題答案相關句) End-stage kidney failure is rising fast， with 400，000 people requiring dialysis or transplant to survive， a toll that has doubled in each of the last two decades.
And while CKD patients often are terrified of having to go on dialysis， the hard truth is that most will die of heart disease before their kidney disintegrate to that point， something kidney specialists have recognized for several years but isn’t widely known. Indeed(的確，確實)， the new research(研究) is highlighted (使突出)in this months Archives of Internal Medicine with a call for (要求)doctors who care for heart patients to start rigorously (嚴格地)checking out (檢查)the kidneys， and for better care of (照顧， 檢查)early(早期的) kidney disease(疾病 ).
第4段最后一句說“《內科檔案》雜志號召為心臟病人治病的醫生要開始嚴格地檢查病人的腎”，因此D是答案。

A Levels(水平， 含量) of the protein(蛋白質) albumin(白蛋白) in the urine(尿).
B Levels of the white blood cells(白細胞) in the blood(血液).
C The rate(比率) at which kidneys filter(滲透) blood.
D. whether (是否)one is anemic(貧血的) or not
5.B. 利用問題句中出現的涉及到數字的細節信息結構(three markers of kidney function)作為答案線索， 同時關注備選項中的詞語/結構是否在答案線索結構所在的語句中， 或答案線索結構所在的周邊的語句中出現了：
And while CKD patients often are terrified of having to go on dialysis， the hard truth is that most will die of heart disease before their kidney disintegrate to that point， something kidney specialists have recognized for several years but isn’t widely known.(第4題答案相關句) Indeed， the new research is highlighted in this months Archives of Internal Medicine with a call for doctors who care for heart patients to start rigorously checking out the kidneys， and for better care of early kidney disease.
The link sounds logical. After all ， high blood pressure and diabetes are chief risk factors both chronic kidney disease and heart attacks. But the link goes beyond those risk factors， stresses McCullough; Once the kidneys begin to fail， something in turn accelerates disease， not just in the obviously sick or very old， but at what he calls "a shockingly age. " McCullough and colleagues tracked more than 37， 000 relatively young people -rage age 53 - who volunteered for a kidney screening. Three markers of kidney function were checked(檢查): The rate at which kidneys filter(滲透) blood， called (被稱為...的)the GFR or glomerular filtration rate" t; levels(含量) of the protein albumin (白蛋白)in the urine; and if they were anemic(貧血的). They also were asked about previously diagnosed heart disease.
The odds of having heart disease rose steadily as each of the striking markers were worsened. More striking was the death data. At this age， few deaths are people died during the study period. But those who had both CKD and known heart disease had a threefold increased risk of death in a mere 2 1/2 years， mostly from heart problems. “This study is very much a wake-up call，” McCullough says.
根據文章倒數第2段中第2句可以直接判定答案。 只有選項B沒有出現在該句中。
