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 ill
B:sleeping a lot could be harmful
C:regular health checks are essential to keeping fit
D:prevention is more difficult than care

Millions of Americans lie awake at night counting sheep, or have a stiff drink or pop an allergy pill, hoping it will make them drowsy. But experts agree all that self-medicating is a bad idea, and the causes of chronic insomnia remain mysterious.
Almost a third of adults have trouble sleeping, and about 10 percent have symptoms of daytime impairment that signal true insomnia. Sufferers readily cite the resulting problems: walking around in a fog, as memory and other cognitive functions slowly. Dozing off at the wheel or at work. Depression. Lack of energy. But for all the complaints, scientists know surprisingly little about what causes chronic insomnia, its health consequences and how best to treat it, a panel of specialists brought together by the National Institutes of Health concluded Wednesday.
Two things are clear, the panel found: Chronic insomnia is a major public health problem. And too many people are using unproven therapies, even while there are a few treatments that do work.
Among the panel′ s findings: Cognitive/behavioral therapy--a psychology-based treatment that trains people to reduce anxiety and take other sleep-promoting steps--is very effective, and doesn′t cause side effects. But it can be hard to find health providers trained in the techniques. Insomniacs should check with board-certified sleep specialists and psychologists.
Newer prescription sleep pills called Sonata, Ambien and Lunesta work without many of the side-effect concerns of older agents known as benzodiazepines (苯二氮类镇静药). One study of Lunesta showed effectiveness with six months of use, but more research on long-term use of all three is needed, as chronic insomnia can linger for years.
The most commonly used treatments are alcohol and over-the-counter sedating antihistamines (抗组胺剂) like Benadryl. Alcohol use actually disrupts quality sleep, and antihistamines can cause
lingering daytime sedation and other cognitive problems.
The most common prescription insomnia medicine is an older, sedating antidepressant called trazodone, even though there′s no good evidence that it offers more than a two-week benefit, and it comes with side effects.
One of most effective ways to deal with choric insomnia is __________.

A.to have a stiff drink
B.to pop an allergy pill
C.to sleep and get up early
D.cognitive/behavioral therapy

I′ve often wondered how exactly sleep, or lack of it, can have such an awful effect on our bodies and, guess what, how much we sleep switches good genes on and bad genes off.
In the first half of 2013, the Sleep Research Centre at the University of Surrey found a direct link between hours spent sleeping and genes. Every cell in our bodies carries genetic instructions in our DNA that act as a kind of operating handbook. However, each cell only "reads" the part of this handbook it needs at any given moment.
Can sleep affect how a gene reads instructions It′s a question asked by Professor Derk-Jan Dijk at the University of Surrey. He set up an experiment and asked his volunteers to spend a week sleeping around seven and a half hours to eight hours a night and the next sleeping six and a half to seven hours.
Blood samples were taken each week to compare which genes in blood cells were being used during the long and short nights. The results were rather surprising. Several hundred genes changed in the amount they were being used, including some that are linked to heart disease, cancer, and Type 2 diabetes. Genes to do with cell repair and replacement were used much less.
Sleep restriction (six and a half to seven hours a night) changed 380 genes. Of these,220 genes were down regulated (their power was reduced), while 160 were up regulated (their power was increased). Those affected included body-clock genes which are linked to diabetes. One of the most downgraded genes is that which has a role in controlling insulin and is linked to diabetes and insomnia. The most upgraded gene is linked to heart disease.
So changing sleep by tiny amounts can upgrade or downgrade genes that can influence our health and the diseases we suffer from when we sleep too little.
The important message is that getting close to eight hours of sleep a night can make a dramatic difference to our health in just a few days through the way it looks after our genes.

Which of the following can be inferred from the findings of the sleep research 查看材料

A.When there is a sleep restriction, genes to do with cell repair and replacement function less.
B.In a sleep, several hundred genes change in the amount. The more changes, the worse results.
C.When genes are up regulated, they do good to health; when genes arc down regulated, they do harm to health.
D.Eight hours of sleep a day can be beneficial to our health in that it looks after our genes.

Questions 7 1~75 refer to the following information.
Family caregivers of seniors should be cognizant of stress as it relates to their loved ones. Knowing the signs and detecting them early can help seniors learn to recognize stress factors and to take steps to alleviate the effects stress can cause. Activities such as yoga, walking and other physical exercises designed for seniors are great tension relievers. Many seniors enjoy the benefits of tai chi classes geared to their physical abilities. The Mayo Clinic supports this gentle form of martial arts as a way to relieve stress and help other health-related conditions.
Some seniors are unable to participate in physical activities, but there are other ways to reduce stress. Eating a healthy, well-balanced diet and getting a good night's sleep can keep stress at bay. Joining a non-physical group activities, such as a bridge club or volunteering, offers socialization and a chance to clear the mind of daily responsibilities. There are also local agencies that can help with tasks that might cause undue stress for seniors. Respite care organizations can help with housework or grocery shopping. Religious organizations often have groups who can assist seniors with yard work or other strenuous tasks around the home.
The fact that stress is a part of life does not mean that overwhelming stress is a burden seniors have to shoulder all alone. With help, seniors can combat stress and its negative effects. Spend time helping seniors determine what burdens they face. Help them plan ways suited to their lifestyles that are not only fun but that can minimize the pressures stress can cause. By doing so, the quality of life seniors experience can increase, further paving the way for them to lead independent lives within the comfort of their own homes.

What kind of physical activities may NOT help seniors relieve tension?

A. Yoga
B. Walking
C. Martial arts

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.

Millions of Americans lie awake at night counting sheep, or have a stiff drink or pop an allergy pill, hoping it will make them drowsy. But experts agree all that self-medicating is a bad idea, and the causes of chronic insomnia remain mysterious.
Almost a third of adults have trouble sleeping, and about 10 percent have symptoms of daytime impairment that signal true insomnia. Sufferers readily cite the resulting problems: walking around in a fog, as memory and other cognitive functions slowly. Dozing off at the wheel or at work. Depression. Lack of energy. But for all the complaints, scientists know surprisingly little about what causes chronic insomnia, its health consequences and how best to treat it, a panel of specialists brought together by the National Institutes of Health concluded Wednesday.
Two things are clear, the panel found: Chronic insomnia is a major public health problem. And too many people are using unproven therapies, even while there are a few treatments that do work.
Among the panel′ s findings: Cognitive/behavioral therapy--a psychology-based treatment that trains people to reduce anxiety and take other sleep-promoting steps--is very effective, and doesn′t cause side effects. But it can be hard to find health providers trained in the techniques. Insomniacs should check with board-certified sleep specialists and psychologists.
Newer prescription sleep pills called Sonata, Ambien and Lunesta work without many of the side-effect concerns of older agents known as benzodiazepines (苯二氮类镇静药). One study of Lunesta showed effectiveness with six months of use, but more research on long-term use of all three is needed, as chronic insomnia can linger for years.
The most commonly used treatments are alcohol and over-the-counter sedating antihistamines (抗组胺剂) like Benadryl. Alcohol use actually disrupts quality sleep, and antihistamines can cause
lingering daytime sedation and other cognitive problems.
The most common prescription insomnia medicine is an older, sedating antidepressant called trazodone, even though there′s no good evidence that it offers more than a two-week benefit, and it comes with side effects.
Which of the following symptoms does NOT belong to insomnia?

A.Walking around in a fog.
B.Lack of energy.
C.Nap irregularly.
D.Cognitive functions loss.
