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.

You'll find it hard to move the way you want to__________.
A:what affects muscles all through your body
B:if there isn't enough dopamine in your body
C:which cannot be cured yet
D:which may be the first symptom you notice
E:if you have a fixed or blank expression

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.

Which of the following statements about the Alzheimer's disease is NOT true?
A:It was so named because Alois Alzheimer first described it.
B:It is the greatest cause of mental deterioration in older people.
C:It can gradually destroy memory and eventually cause death.
D:There are many ways to deal with and cure the disease now.

Depression

Everyone occasionally feels blue or sad.But these feelings are usually short-lived and pass within a couple of days.Depression is a common but serious illness.
Major depression prevents a person from functioning normally.It interferes with a person's ability to work,sleep,study,eat,and enjoy once-pleasurable activities.Minor depression is character-ized by having symptoms for 2 weeks or longer that do not meet full criteria for major depression. Without treatment,people with minor depression are at high risk for developing major depressive disorder.
The severity,frequency,and duration of symptoms vary depending on the individual and his or her particular illness.They include persistent sad,anxious,feelings of hopelessness,guilt,worth-lessness,or helplessness,loss of interest in activities or hobbies once-pleasurable,fatigue and decreased energy,difficulty in concentrating,remembering details,and making decisions,insomnia, early-morning wakefulness,or excessive sleeping,suicide attempts.
Depression also may occur with other serious medical illnesses such as heart disease,stroke, cancer,HI V/AIDS,diabetes,and Parkinson's disease.
Depression is related to a combination of genetic,biological,environmental,and psychological factors.Research indicates that depressive illnesses are disorders of the brain.Brain-imaging tech-nologies,such as magnetic resonance imaging(MRI),have shown that the brains of people who have depression look different than those of people without depression.Some types of depression tend to run in families.In addition,trauma,loss of a loved one,a difficult relationship,or any stressful situation may trigger a depressive episode.
Biological,life cycle,hormonal,and psychosocial factors that women experience may be related to women's higher depression rate.For example,women are especially vulnerable to developing postpartum depression after giving birth.Besides,during the transition into menopause,some women experience an increased risk for depression.It is still unclear,though,why some women faced with enormous challenges develop depression,while others with similar challenges do not.

If a person suffers from minor depression,he may have________.
A:feelings of guilt or worthlessness
B:developing postpartum depression after giving birth
C:going through a transition into menopause
D:symptoms for 2 weeks that is slightly different from major depression
E:his family member has depression too
F: heart disease,stroke,cancer,HIV/AIDS,diabetes,and Parkinson's disease

We live in a moment packed with new possibilities,and we've never been better equipped to seize them.The problem is that many of us don't feel it.If this is the best time to be alive,it certainly hasn't becn the easiest.This upheaval has created winners:among owners ofcapital;among entrepreneurs who have grown into new markets;and among individuals whose skills,acumen or luck helps them to navigate this tangle.But it has also created losers:among pensioners and homeowners whose savings were destroyed by unforeseen financial risks;among workers whose jobs are now being done overseas by people escaping from poverty;among those whose jobs stayed onshore but are being replaced by machines;among farmers whose crops are failing because of climate change;among citizens in countries where a small elite are siphoning the benefits of global integration into offshore bank accounts.

Depression

Everyone occasionally feels blue or sad.But these feelings are usually short-lived and pass within a couple of days.Depression is a common but serious illness.
Major depression prevents a person from functioning normally.It interferes with a person's ability to work,sleep,study,eat,and enjoy once-pleasurable activities.Minor depression is character-ized by having symptoms for 2 weeks or longer that do not meet full criteria for major depression. Without treatment,people with minor depression are at high risk for developing major depressive disorder.
The severity,frequency,and duration of symptoms vary depending on the individual and his or her particular illness.They include persistent sad,anxious,feelings of hopelessness,guilt,worth-lessness,or helplessness,loss of interest in activities or hobbies once-pleasurable,fatigue and decreased energy,difficulty in concentrating,remembering details,and making decisions,insomnia, early-morning wakefulness,or excessive sleeping,suicide attempts.
Depression also may occur with other serious medical illnesses such as heart disease,stroke, cancer,HI V/AIDS,diabetes,and Parkinson's disease.
Depression is related to a combination of genetic,biological,environmental,and psychological factors.Research indicates that depressive illnesses are disorders of the brain.Brain-imaging tech-nologies,such as magnetic resonance imaging(MRI),have shown that the brains of people who have depression look different than those of people without depression.Some types of depression tend to run in families.In addition,trauma,loss of a loved one,a difficult relationship,or any stressful situation may trigger a depressive episode.
Biological,life cycle,hormonal,and psychosocial factors that women experience may be related to women's higher depression rate.For example,women are especially vulnerable to developing postpartum depression after giving birth.Besides,during the transition into menopause,some women experience an increased risk for depression.It is still unclear,though,why some women faced with enormous challenges develop depression,while others with similar challenges do not.

The symptoms of depression,besides fatigue,may include__________.
A:feelings of guilt or worthlessness
B:developing postpartum depression after giving birth
C:going through a transition into menopause
D:symptoms for 2 weeks that is slightly different from major depression
E:his family member has depression too
F: heart disease,stroke,cancer,HIV/AIDS,diabetes,and Parkinson's disease
