Hair Care
Whether the hair is long or short,it must be regularly brushed and regularly washed.For greasy（油性的）hair , especially if the owner lives in a town , it may be necessary to wash the head every four to five days.Those with a dry hair can usually go a little longer,but this is a matter for the individual to decide.
As for style,this must be studied according to what is the latest fashion and also to suit the individual at different times of her life.If a woman is not able to go to hairdresser very often,it is important that she chooses a style she can easily manage for herself,and this nearly always means that the first cut must be very standard. The same applies to permanent waving（烫发）.I think that this should be carried out three or four times a year,so that the hair never gets out of hand.
One thing would be remembered though,that is,whatever you apply to the head can have some effect upon the skin and therefore anything strong should be used with care.Or you may use milder products.
Young people who has spots or skin troubles on their face should take particular care to ensure that the hair is both clean and does not come into contact with the affected piece of skin.Hair is very difficult to keep completely clean and therefore anyone running their hands through their hair and afterwards touching their face,or letting their hair fall over their faces,might spread in- fection from one place to another.
Good hair does a lot to the effect of a face,so if you want to look charming,please start with your hair.

To prevent the hair from infecting the skin,we'd better______.
A: keep the hair completely clean
B: wash the hair very often
C: have hair cut four times a year
D: avoid combing the hair with our hands

Sunbath and Skin Cancer
In the summer,millions of Americans will offer up their bodies to the sun rays.A tan mndi-cates health and beauty,and most sun worshippers will sacrifice a lot to achieve it,including themselves.
With each hour, the sun's ultraviolet radiation (紫外线）produces irreversible（不可逆的） damage,hastening the development of unsightly wrinkles.And with each year on the beach or roof-top,the sunbather increases his risk of getting skin cancer. Skin cancer is by far the most common form of cancer. An estimated 400,000 new cases will be detected this year in the United States, and almost all of them can be blamed on over-exposure to the sun.
Fortunately,most of these cancers are highly curable .But they can he disfiguring and take time to treat. For that reason,sun worshippers should treat deity with a good deal of awe（敬畏）. Sunburn,of course,is the initial hazard posed by UV radiation.Prolonged exposure to UV,howev-er , interferes with the production of collagen fibers（胶原纤维）in the dermis（真皮层）, causing the skin to lose elasticity（弹性）and creating premature wrinkles. Further deterioration（恶化）of the dermis deprives the epidermis（表皮层）of nutrition and causes it to become thin and dry.
Cancer is UV's final result.Shortwave radiant energy,especially from the UV-B band,breaks the strands（股、缕）of DNA. Enzymes（酶）work constantly to rearrange the DNA into proper Se-quence,but with repeated UV exposure,the repair process may eventually break down.Then the mutant（变异的）DNA may produce a colony of cancer cells. But skin cancer may be avoided with a good dose of common sense.People with fair skin and blue eyes who burn easily stand the high-est risk .Special danger spots are the parts of the body most constantly exposed to the sun,such as the cheeks , nose , lower lip and the ears. People who have already developed precancerous（癌变前的）lesions（伤害）or had one skin-cancer growth stand a greatly increased chance of developing others.
Dermatologists（皮肤科医生）recommend avoiding the sun when it is most intense between 11 a.m.and 3 p.m.Anyone who insists on sunbathing should use a good sun screen.These lotions and salves（药膏）contain chemicals that block out the burning UVB radiation while permitting the tanning rays to reach the skin.

The last paragraph of the passage mainly discusses_______.
A: the treatment of the skin cancer
B: the prevention of the skin cancer
C: the parts of the body where cancer is most likely to develop
D: the lotions that work best in fighting against the skin cancer

Physician-assisted Suicide

1.The Supreme Court's decisions on physician-assisted suicide carry important implications forhow medicine seeks to relieve dying patients of pain and suffering.
2.Although it ruled that there is no constitutional right to physician-assisted suicide,the Court in effect supported the medical principle of"double effect,"a centuries-old moral principle holding that an action having two effects一a good one that is intended and a harmful one that is foreseen一is permissible if the actor intends only the good effect.
3.Doctors have used that principle in recent years to justify using high dose of morphine to control terminally ill patients' pain,even though increasing dosages will eventually kill the patient.
4.Nancy Dubler,director of Montefiore Medical Center,contends that the principle will shield doctors who until now have very,very strongly insisted that they could not give patients sufficient medication to control their pain if that might hasten death.
5.George Annas,chair of the health law department at Boston University,maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose,the doctor has done nothingillegal even if the patient uses the drug to hasten death."It's like surgery,"he says."We don't callthose deaths homicides because the doctors didn't intend to kill their patients,although they risked their death.If you're a physician,you can risk your patient's suicide as long as you don't intend theirsuicide."On another level,many in the medical community acknowledge that the assisted-suicide debate has been fueled in part by the despair of patients for whom modern medicine has prolonged the physical agony of dying.
6.Just three weeks before the Court's ruling on physician-assisted suicide,the National Academy of Science(NAS)released a two-volume report,Approaching Death:Improving Care atthe End of Life.It identifies the under-treatment of pain and the aggressive use of"ineffectual and forced medical procedures that may prolong and even dishonor the period of dying" as the twin problems of end-of-life care.
7. The profession is taking steps to require young doctors to train in hospices（临终关怀医院）, to test knowledge of aggressive pain management therapies,to develop a Medicare billing code for hospital-based care,and to develop new standards for assessing and treating pain at the end of life. Annas says lawyers can play a key role in insisting that these well-meaning medical initiatives trans-late into better care.

A:Doctors' Practice of the Principle
B:The Effects of Modern Medicine to Their Illness
C:The Decision of Physician-assisted Suicide
