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 getting this neurological
（神经病学的）disorder.
The only current means of diagnosing 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 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,Maryland."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.
Researchers discovered 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 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 govern 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 he cautioned that other promising tests for Alzheimer's
have been disappointing.

What is the relationship between Alzheimer's and dementia?
A:Dementia is one of the signs of Alzheimer's.
B:Alzheimer's is one of the causes of dementia.
C:They are two completely different diseases.
D:They are similar defects of the human brain.

参考答案

参考解析

解析：由文章第一段的内容可知，皮肤试验的最终目的在于“ultimately allow physicians to pre-dict who is at risk of getting this neurological disorder"，所以只有C项符合题意。
根据文章第二段的内容可知，痴呆病很难确诊，它的诊断是一个漫长且代价昂贵的过程，故D项正确。
由文章第四段最后一句“There is currently no known treatment for the disease.”可知，D 项的内容与此不符，故选D。
第五段中谈到了两者的关系："Alzheimer' s results from physiological changes … and that dementia may be the first noticeable effect of these changes…"，也就是说痴呆病是阿尔茨海默氏病的表现之一。
最后一段发言人谈到这一试验的前途时较为含蓄，只说试验如能证明有效自然是一大发展，但他同时提醒人们以前的试验看上去也很有前途，结果却令人失望。因此，只有C项符合题意。

考题共用题干第二篇As we have seen,the focus of medical care in our society has been shifting from curing disease to preventing disease一especially in terms of changing our many unhealthy behaviors,such as poor eating habits,smoking,and failure to exercise.The line of thought involved in this shift can be pursued further. Imagine a person who is about the right weight , but does not eat very nutritious（有营养的）foods , who feels OK but exercises only occasionally , who goes to work every day , but is not an outstanding worker,who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts,but sleeps a lot and often feels tired.This person is not ill.He may not even be at risk for any particular disease.But we can imagine that this person could be a lot healthier.The field of medicine has not traditionally distinguished between someone who is merely "not ill" and someone who is in excellent health and pays attention to the body's special needs.Both types have simply been called "well".In recent years,however,some health specialists have begun to apply the terms "well" and "weilness" only to those who are actively striving to maintain and improve their body's condition.Most importantly,perhaps,people who are well take active responsibility for all matters related to their health.Even people who have a physical disease or handicap（缺陷）may be "well" ,in this new sense,if they make an effort to maintain the best possible health they can in the face of their physical limitations."Wellness" may perhaps best be viewed not as a state that people can achieve,but as an ideal that people can strive for. People who are well are likely to be better able to resist disease and to fight disease when it strikes.And by focusing attention on healthy ways of living,the concept of weilness can have a beneficial impact on the way in which people face the challenges of daily life.The first paragraph implies that_________.A:good health is more than not being illB:sleeping a lot could be harmfulC:regular health checks are essential to keeping fitD:prevention is more difficult than care

考题共用题干第三篇Cheating is when a person misleads,deceives,or acts dishonestly on purpose.For kids,cheating may happen at school,at home,or while playing a sport.A new study finds that most high school students say they have cheated on tests and homework.This study showed that 89 percent said glancing at someone else's answers during a test was cheating,but 87 percent said they'd done that at least once.Also,94 percent said providing answers to someone during a test was cheating,but 74 percent admitted to doing it.Cheating can happen in a lot of different ways.You can do it by sneaking answers to a test,but it's also cheating to break the rules of a game or contest or to pretend something is yours when it isn't. When people cheat,it's not fair to other people,like the kids who studied for the test or who were the true winners of a game or contest. If students today want to cheat,they have a more insidious tool at their disposal:cellphones.More than one third of teens with cellphones admit to having stored information on them to look at during a test or texting friends about answers.Some kids cheat because they're busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can't pass the test without cheating. Even when there seems to be a "good reason"for cheating,cheating isn't a good idea. Kids who cheat may feel worried about getting caught.Whether they are caught or not,these kids may feel guilty,or embarrassed,or ashamed,or all three.Teachers can ban cell phones in exams and principals can suspend or expel students who cheat,but it's important to know if students continue to cheat they will have a lot of problems in the future.What do the statistics in the second paragraph indicate?A:Most students are honest.B:Cheating in school is a serious problem.C:In a test,providing answers to others is more serious than glancing at people's answers.D:Tests are difficult.

考题共用题干第一篇ObesityObesity refers to the medical condition characterized by storage of excess body fat. The human body naturally stores fat tissue under the skin and around organs and joints.Fat is critical for good health because it is a source of energy when the body lacks the energy necessary to sustain life processes,and it provides insulation and protection for internal organs.But too much fat in the body is associated with a variety of health problems.Most physicians use the body mass index(BMI)to determine desirable weights.BMI is calculated as weight divided by height and people with a BMI of 27 or above are considered obese.Weight-height tables,such as those published by the Metropolitan Life Insurance Company,are also used as general measures of desirable weight ranges.These tables assign a range of weights for a particular height.For example,a man of 1.8m has a desirable range of 66 to 83 kg,with an average of 75 kg. A woman who is 1.6 m has a desirable range between 53 and 70 kg,with an average of 62 kg.The BMI and weight-height tables only provide rough estimates of desirable weights and scientists recognize that many other factors besides height affect weight. Weight alone may not be an indicator of fat,as in the case of a body-builder who may have a high BMI because of a high percentage of muscle tissue,which weighs more than fat. Likewise,a person with a sedentary lifestyle may be within a desirable weight range but have excess fat tissue.Obesity increases the risk of developing disease.According to some estimates,almost 70 percent of heart disease cases are linked to excess body fat,and obese people are more than twice as likely to develop high blood pressure.Obese women are at nearly twice the risk for developing breast cancer,and all obese people have an estimated 42 percent higher chance of developing colon cancer. The risk of medical complications particularly heart disease increases when body fat is distributed around the waist,especially in the abdomen.This type of upper body fat distribution is more common in men than in women.The social and psychological problems experienced by obese people are also formidable.Stereotypes about"fat"people are often translated into discriminatory practices in education,employment, and social relationships.The consequences of being obese in a world where people had better be "thin"are especially severe for women,whose appearances are often judged against and ideal of exaggerated slimness.According to this article,fat people may be_________.A:looked down upon by othersB:welcomed by othersC:considered severely illD:thought of having special problems

The human body naturally stores fat tissue under the skin and around organs and joints.Fat is critical for good health because it is a source of energy when the body lacks the energy necessary to sustain life processes,and it provides insulation and protection for internal organs.But too much fat in the body is associated with a variety of health problems.Most physicians use the body mass index(BMI)to determine desirable weights.BMI is calculated as weight divided by height and people with a BMI of 27 or above are considered obese.Weight-height tables,such as those published by the Metropolitan Life Insurance Company,are also used as general measures of desirable weight ranges.These tables assign a range of weights for a particular height.For example,a man of 1.8m has a desirable range of 66 to 83 kg,with an average of 75 kg. A woman who is 1.6 m has a desirable range between 53 and 70 kg,with an average of 62 kg.The BMI and weight-height tables only provide rough estimates of desirable weights and scientists recognize that many other factors besides height affect weight. Weight alone may not be an indicator of fat,as in the case of a body-builder who may have a high BMI because of a high percentage of muscle tissue,which weighs more than fat. Likewise,a person with a sedentary lifestyle may be within a desirable weight range but have excess fat tissue.Obesity increases the risk of developing disease.According to some estimates,almost 70 percent of heart disease cases are linked to excess body fat,and obese people are more than twice as likely to develop high blood pressure.Obese women are at nearly twice the risk for developing breast cancer,and all obese people have an estimated 42 percent higher chance of developing colon cancer. The risk of medical complications particularly heart disease increases when body fat is distributed around the waist,especially in the abdomen.This type of upper body fat distribution is more common in men than in women.The social and psychological problems experienced by obese people are also formidable.Stereotypes about"fat"people are often translated into discriminatory practices in education,employment, and social relationships.The consequences of being obese in a world where people had better be "thin"are especially severe for women,whose appearances are often judged against and ideal of exaggerated slimness.A heavy man ________.A:certainly has a lot of fat in himB:usually has a sedentary lifestyleC:certainly has a lot muscle in himD:may have muscle tissue that weighs more than fat

考题共用题干第一篇More About Alzheimer' s DiseaseScientists 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 getting this neurological （神经病学的）disorder.The only current means of diagnosing 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 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,Maryland."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.Researchers discovered 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 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 govern 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 he 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 youngB:not costly to be curedC:easy to be handledD:not easy to be diagnosed
