Natural Medicines
Since earliest days,humans have used some kinds of medicines.We know this because humans have survived.Ancient treatments for injury and disease were successful enough to keep humans from dying out completely.
They were successful long before the time of modern medicine. Before the time of doctors with white coats and shiny（发亮的）instruments. Before the time of big hospitals with strange and wonderful equipment.
Many parts of the world still do not have university-educated doctors. Nor do they have expensive hospitals.Yet injuries are treated.And diseases are often cured.How?By ancient methods. By medicines that might seem mysterious , even magical（有魔力的）.Traditional medicines are neither mysterious nor magical,however.
Through the centuries , tribal（部落的）medicine men experimented with plants. They found
many useful chemicals in the plants.And scientists believe many of these traditional medicines
may provide the cure for some of today's most serious diseases.
Experts say almost 80% of the people in the world use plants for health care.These natural medicines are used not just because people have no other form of treatment. They are used because people trust them. In developed areas,few people think about the source of the medicines they buy in a store .Yet many widely-used medicines are from ancient sources,especially plants.
Some experts say more than 25%of modem medicines come,in one way or another,from nature.
Scientists have long known that nature is really a chemical factory. All living things contain chemicals that help them survive .So scientists' interest in traditional medicine is not new.But it has become an urgent concern.This is because the earth's supply of natural medicines may be dropping rapidly.
The passage indicates that ancient treatments for injury and disease were
A: much more successful than modem ones
B: successful enough for humans to survive
C: successful in all cases
D: of little help to humans

Early or Later Day Care
The British psychoanalyst John Bowiby maintains that separation from the parents during the sensitive "attachment"period from birth to three may scar a child's personality and predispose to emotional problems in later life.Some people have drawn the conclusion from Bowlby's work that children should not be subjected to day care before the age of three because of the parental separation it entails,and many people do believe this.But there are also arguments against such a strong conclusion.
Firstly,anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies.For example,in some tribal societies,such as the Ngoni,the father and mother of a child did not rear their infant alone-far from it.Secondly,common sense tells us that day care would not be so widespread today if parents,care-takers found children had problems with it.Statistical studies of this kind have not yet been carried out,and even if they were,the results would be certain to be complicated and controversial.Thirdly,in the last decade there have been a number of careful American studies of children in day care,and they have uniformly reported that day care had a neutral or slightly positive effect on children's development.But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.
But Bowlby's analysis raises the possibility that early day care has delayed effects.The possibility that such care might lead to,say,more mental illness or crime 15 or 20 years later can only be explored by the use of statistics.Whatever the long-term effects,parents sometimes find the immediate effects difficult to deal with.Children under three are likely to protest at leaving their parents and show unhappiness.At the age of three or three and a half almost all children find the transition to nursery easy,and this is undoubtedly why more and more parents make use of child care at this time.The matter,then,is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.
Which of the following is derivable from Bowiby's work?
A:Mothers should not send their children to day care centers before the age of three.
B:Day care nurseries have positive effects on a child's development.
C:A child sent to a day care center before the age of three may have emotional problems in later life.
D:Day care would not be so popular if it has noticeable negative effects on a child's personality.
