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.
The newly developed skin tests may be used in the future to allow doctors to________.
A:cure those with Alzheimer's disease
B:discover the cause of Alzheimer's disease
C:predict who might get Alzheimer's disease
D:find the consequences of Alzheimer's disease

Parkinson's Disease
1 Parkinson's disease affects the way you move.It happens when there is a problem with certain nerve
cells in the brain. Normally , these nerve cells make an important chemical called dopamine（多巴胺）. Dopa-
mine sends signals to the part of your brain that controls movement.It lets your muscles move smoothly and
do what you want them to do.When you have Parkinson's,these nerve cells break down.Then you no longer
have enough dopamine,and you have trouble moving the way you want to.
2 No one knows for sure what makes these nerve cells break down.But scientists are doing a lot of re-
search to look for the answer. They are studying many possible causes,including aging and poisons in the en-
vironment.Abnormal genes seem to lead to Parkinson's disease in some people.But so far,there is not enough
proof to show that it is always inherited.
3 Tremor（颤抖）may be the first symptom you notice.It is one of the most common signs of the
disease,although not everyone has it.Tremor often starts in just one arm or leg or only on one side of the
body.It may be worse when you are awake but not moving the affected arm or leg. It may get better when you
move the limb or when you are asleep.In time,Parkinson's affects muscles all through your body,so it can
lead to problems like trouble swallowing or constipation（便秘）.In the later stages of the disease , a person
with Parkinson's may have a fixed or blank expression,trouble speaking,and other problems.Some people
also have a decrease in mental skills.
4 At this time,there is no cure for Parkinson's disease.But there are several types of medicines that
can control the symptoms and make the disease easier to live with.You may not even need treatment if your
symptoms are mild.Your doctor may wait to prescribe medicines until your symptoms start to get in the way of
your daily life.Your doctor will adjust your medicines as your symptoms get worse.You may need to take
several medicines to get the best results.

Intelligence一a Changed View
1.Intelligence was believed to be a fixed entity,some faculty of the mind that we all possess and which determines in some way the extent of our achievements.its value therefore,was as a predictor of children's future learning.If they differed markedly in their ability to learn complex tasks, then it was clearly necessary to educate them differently and the need for different types of school and even different ability groups within school was obvious.Intelligence tests could be used for streaming children according to ability at an early age,and at 11 these tests were superior to measures of attainment for selecting children for different types of secondary education.
2.Today,we are beginning to think differently. In the last few years,research has thrown doubt on the view that innate intelligence can ever be measured and on the very nature of intelligence itself. There is considerable evidence now which shows the great influence of environment both on achievement and intelligence.Children with poor home backgrounds not only do less well in their school work and intelligence tests but their performance tends to deteriorate gradually compared with that of their more fortunate classmates.
3.There are evidences that support the view that we have to distinguish between genetic intelligence and observed intelligence.Any deficiency in the appropriate genes will restrict development no matter how stimulating the environment. We cannot observe and measure innate intelligence,whereas we can observe and measure the effects of the interaction of whatever is inherited with whatever stimulation has been received from the environment. Researches have been investigating what happens in this interaction.
4.Two major findings have emerged from these researches.Firstly,the greater part of the development of observed intelligence occurs in the earliest years of life.It is estimated that 50 percent of measurable intelligence at age 17 is already predictable by the age of four. Secondly,the most important factors in the environment are language and psychological aspects of the parent-child relationship.Much of the difference in measured intelligence between "privileged" and "disadvantaged" children may be due to the latter's lack of appropriate verbal stimulation and the poverty of their perceptual experiences.
5.These research findings have led to a revision in our understanding of the nature of intelligence.Instead of it being some largely inherited fixed power of the mind,we now see it as a set of development skills with which a person copes with any environment. These skills have to be learned and,indeed,one of them is learning how to learn.
6.The modern ideas concerning the nature of intelligence are bound to have some effect on our school system. In one respect a change is already occurring. With the move toward comprehensive education and the development of unstreamed classes,fewer children will be given the label "low IQ"which must inevitably condemn a child in his own,if not society's eyes. The idea that we can teach children to be intelligent in the same way that we can teach them reading or arithmetic is accepted by more and more people.
It was once believed_________,and thus we can tell how successful he/she will be in the future according to his/her intelligence.
A:born to be more intelligent or less intelligent
B:have a better chance to develop his intelligence
C:taught to be more intelligent
D:that intelligence was something a baby was born with
E:and because of the lack of communication with his classmates
F: and partly has to do with a child's living environment

1.All research to date on body image shows that women are much more critical of their appearance than men and much less likely to admire what they see in the mirror. Up to 8 out of 10 women are dissatisfied with their reflection,and more than half may see a distorted image.
2.Men looking in the mirror are more likely to be either pleased with what they see or indifferent. Research shows that men generally have a much more positive body-image than women一if anything,they may tend to over-estimate their attractiveness.Some men looking in the mirror may literally not see the flaws in their appearance.
3.Why are women too much more self-critical than men?Because women are judged on their appearance more than men,and standards of female beauty are considerably higher and more inflexible.Women are continually bombarded with images of the inflexible.Women are continually bombarded with images of the"ideal"face.And constant exposure to idealized images of female beauty on TV,magazines and billboards makes exceptional good looks seem normal and anything short of perfection seem abnormal and ugly.It has been estimated that young women now see more images of outstandingly beautiful women in one day than our mothers saw throughout their entire adolescence.
4.Also,most women are trying to achieve the impossible:standards of female beauty have in fact become progressively more unrealistic during the last century.In 1917,the physically perfect woman was about 5 feet 4 inches tall and weighed nearly 10 stone（约140磅）.Even 25 years ago, top models and beauty queens weighed only 8% less than the average woman,now they weigh 23% less.The current media ideal for women is achievable by less than 5% of the female population一and that's just in terms of weight and size.If you want the ideal shape,face,etc, it's probably more like 1%.
