Schooling and Education
It is commonly believed in the United States that school is where people go to get an education.Nevertheless, it has been said that today children interrupt their education to go to school.The distinction between schooling and education implied by this remark is important.Education is much more open-ended and all-inclusive than schooling.Education knows no bounds.It can take place anywhere, whether in the shower or in the job, whether in a kitchen or on a tractor.It includes both the formal learning that takes place in schools and the whole universe of informal learning.The agents of education can range from a revered grandparent to the people debating politics on the radio, from a child to a distinguished scientist.
Whereas schooling has a certain predictability, education quite often produces surprises.A chance conversation with a stranger may lead a person to discover how little is known of other religions.People are engaged in education from infancy on.Education,then,is a very broad, inclusive term.It is a lifelong process, a process that starts long before the start of school, and one that should be an integral part of one’s entire life.Schooling, on the other hand, is a specific, formalized process, whose general pattern varies little from one setting to the next.
Throughout a country, children arrive at school at approximately the same time, take assigned seats, are taught by an adult, use similar textbooks, do homework, take exams, and so on.The slices of reality that are to be learned, whether they are the alphabet or an understanding of the workings of government, have usually been limited by the boundaries of the subject being taught.For example, high school students know that they are not likely to find out in their classes the truth about political problems in their communities or what the newest filmmakers are experimenting with. There are definite conditions surrounding the formalized process of schooling.

Car Crime
1 A million motorists leave their cars filled up with petrol and with the keys in the ignition every day.The cars are sitting in petrol stations while drivers pay for their fuel.The Automobile Association (AA) has discovered that cars are left unattended for an average three minutes and sometimes longer as drivers buy drinks, sweets, cigarettes and other consumer items.With payment of credit cards becoming more and more common, it is not unusual for a driver to be out of his car for as long as six minutes, providing the car theft with a golden opportunity.
2.For more than ten years there has been a big rise in car crime than in most other types of crimes.An average of more than two cars a minute are broken into or stolen in the UK.Car crime accounts for almost a third of all reported offenses with no signs that the trend is slowing down.
3.Although there are highly professional criminals involved in car theft, almost 90 percent of car theft is committed by the opportunists.Amateur thieves are aided by our own carelessness.The AA recommends locking up whenever you leave the car and for however short a period.A partially open sunroof or window is a further come-on to thieves.
4.There are many other traps to avoid.The AA has found little awareness among drivers about safe parking.Most motorists questioned made no efforts to avoid parking in quiet spots—just the places thieves’ love.The A A advises drives to park in places with people around-thieves don’t like audiences.
A.Safe parking
B.Increase in car theft
C.Opportunities for non-professionals
D.Anti-theft organizations
E.Drivers’ carelessness: a factor in promoting car stealing
F.Car stealing mostly by professional criminals

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 modern 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.

Hacking
People tend to think of computers as isolated machines, working away all by themselves.Some do—personal computer without an outside link, like someone’s hideaway (隐蔽的) cabin in the woods. But just as most of homes are tied to a community by streets, bus routes and electric lines, computers that exchange intelligence are part of a community—local, national and even global network joined by telephone connections.
The computer network is a creation of the electric age, but it is based on old-fashioned trust.It cannot work without trust. A rogue loose (为所欲为的无赖) in a computer system called hacker (黑客) is worse than a thief entering your house.He could go through anyone’s electronic mail or add to, change, distort or delete anything in the information stored in the computer’s memory.He could even take control of the entire system by placing his own instructions in the software that runs it.He could shut the computer down whenever he wished, and no one could stop him. Then he could program the computer to erase any sign of his ever having been there.
Hacking, our electronic-age term for computer break-in, is more and more in the news-brainy kids vandalizing university records, even pranking (胡闹) about in supposedly safeguarded systems.To those who understand how computer networks are increasingly regulating life in the late 20th century, these are not laughing matters.A potential for disaster is building; A dissatisfied former insurance-company employee wipes out information from payroll (工资表) files.A student sends out a “virus“ , a secret and destructive command, over a national network.The virus copies itself at lightning speed, jamming the entire network—thousands of academic, commercial and government computer systems.Such disastrous cases have already occurred.Now exists the possibility of terrorism by computer.Spoiling a system responsible for air-traffic control at a busy airport, or knocking out the telephones of a major city, is a relatively easy way to spread panic.Yet neither business nor government has done enough to toughen its defenses against attack.For one thing, such defenses are expensive; for another, they may interrupt communication—the main reason for using computers in the first place.
