[不定项选择题]共用题干 More about Alzheimer's Disease
Scientists have developed skin tests that may be used in the future to identify people with Alzheimer's disease and may ultimately allow physicians to predict who is at risk of get-ting this neurological disorder.
The only current means of diagnosing the disease in a living patient is a long and expen-sive series of tests that eliminate every other cause of dementia.
“Since Aloes Alzheimer described the disease nearly a century ago,people have been trying to find a way to accurately diagnose it in its early stages,“said Patricia Grady,acting director of the National Institute of Neurological Disorders and Stroke in Bethesda,Mary-land."This discovery,if confirmed,could prove a big step forward in our efforts to deal with and understand the disease.”
Alzheimer's is the single greatest cause of mental deterioration in older people,affecting between 2.5 million and 4 million people in the United States alone. The devastating disorder gradually destroys memory and the ability to function,and eventually causes death. There is currently no known treatment for the disease.
Researches discovered that the skin cells of Alzheimer's patients have defects that inter-fere 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 results from physiological changes throughout the body,and that dementia may be the first noticeable effect 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 critical element.
One test developed by researches calls for growing skin cells in a laboratory culture and then testing them with an electrical detector to determine if the microscopic tunnels that govemn 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 development,but cautioned that other promising
tests for Alzheimer's have been disappointing. The passage indicates that Alzheimer's is a disease______.
A.common to people,old and young
B.not costly to be cured
C.easy to be handled
D.not easy to be diagnosed

[简答题]"If there were none of this playing at generosity in warfare, we should never go to war, except for something worth facing certain death for, as now. Then there would not be wars because Pavel Ivanitch had insulted Mihail Ivanitch. But if there is war as now, let it be really war. And then the intensity of warfare would be something quite different. All these Westphalians and Hessians Napoleon is leading against us would not have come to fight us in Russia, and we should not have gone to war in Austria and in Prussia without knowing what for. War is not a polite recreation, but the vilest thing in life, and we ought to understand that and not play at war. We ought to accept it sternly and solemnly as a fearful necessity. It all comes to this: have done with lying, and if it’s war, then it’s war and not a game, or else warfare is simply the favourite pastime of the idle and frivolous.... The military is the most honored calling. And what is war, what is needed for success in war, wha
