The man behind this notion, Jack Maple, is a dandy who affects dark glasses, homburgs(翘边帽)and two-toe shoes; yet he has become something of a legend in America’s police departments. For some years, starting in New York and moving on to high-crime spots such as New Orleans and Philadelphia, he and his business partner, John Linder have marketed a two-tier system for cutting crime.First, police departments have to sort themselves out: root out corruption, streamline their bureaucracy, and make more contact with the public. Second, they have to adopt a computer system called Comstat which helps them to analyze statistics of all major crimes. These are constantly keyed into the computer, which then displays where and when they have occurred on a color-coded map, enabling the police to monitor crime trends as they happen and to spot high-crime areas. In New York, Comstat’s statistical maps are analyzed each week at a meeting of the city’s police chief and precinct captains.Messrs Maple and Linder ( "specialists in crime-reduction services" ) have no doubt that their system is a main contributor to the drop in crime. When they introduced it in New Orleans in January 1997, violent crime dropped by 22 % in a year; when they merely started working informally with the police department in Newark, New Jersey, violent crime fell by 13%. Police departments are now lining up to pay as much as $50,000 a month for these two men to put them straight.Probably all these new policies and bits of technical wizardry, added together, have made a big difference to crime. But there remain anomalies that cannot be explained, such as the fact that crime in Washington D.C. , has fallen as fast as anywhere, although the police department has been corrupt and hopeless and, in large stretches of the city, neither police nor residents seem disposed to fight the criminals in their midst.The more important reason for the fall in crime rates, many say, is a much less sophisticated one. It is a fact that crime rates have dropped as the imprisonment rate soared. In 1997 the national incarceration rate, at 645 per 100,000 people was more than double the rate in 1985, and the number of inmates in city and county jails rose by 9.4%, almost double its annual average increase since 1990. Surely some criminologists argue, one set of figures is the cause of the other. It is precise because more people are being sent to prison, they claim that crime rates are falling. A 1993 study by the National Academy of Sciences actually concluded that the tripling of the prison population between 1975 and 1989 had lowered violent crime by 10-15%.Yet cause and effect may not be so obviously linked. To begin with, the sale and possession of drugs are not counted by the FBI in its crime index, which is limited to violent crimes and crimes against property. Yet drug offences account for more than a third of the recent increase in the number of those jailed; since 1980, the incarceration rate for drug arrests has increased by 1,000%. And although about three-quarters of those going to prison for drug offences have committed other crimes as well, there is not yet a crystal-clear connection between filling the jails with drug-pushers and a decline in the rate of violent crime. Again, though national figures are suggestive, local ones diverge: the places where crime has dropped most sharply( such as New York City)are not always the places where incarceration has risen fastest. The meaning of the word "anomalies" in the second line of 4th paragraph is ().

Every year there are reports of people dying as the result of extremely hot weather. Many of the victims are old persons, whose hearts or breathing systems decline. But many die from lack of water.Water is necessary for life and good health. We often forget this fact when we think about the other building blocks of life such as vitamins, minerals and proteins. We can live for many days without eating, but two or three days without water usually leads to death.The human body may look solid, but most of it is water. New born babies are as much as 85% water. Women are about 65% water and men about 75%. Women usually have less water than men because women, in general, have more fat cells, and fat cells hold less water than other kinds of cells.Water does many different things to keep us healthy. It carries hormones, antibodies and foods through the body, and carries away waste materials. That is why different parts of the body contain different amounts of water. For example, blood is 83% water, muscles are 75% water, the brain is 74%, and bones are 25%.Water is also necessary for cooling the body under hot weather and when we are working hard or exercising, water carries body heat tO the surface of the skin, where the heat is lost through perspiration. Researchers say cool liquids cool us faster than warm liquids, because cold liquids take up more heat inside the body and carry it away faster. They say, however, that cold sweet drinks do not work well because the sugar slows the liquid from getting into the blood-stream.Researchers also note that fat ceils block body heat from escaping quickly. Fat cells under the skin act like warm clothing to keep body heat inside. This is why overweight people have a more easy time staying cool than thin people.The body loses water every day through perspiration and urine. If we lose too much, we will become sick. A 10% drop in body water can cause the blood system to fail. A 15%～20% drop usually leads to death. To replace what is lost, health experts say growing persons should drink about 2 liters of liquids each day, and more in hot weather. They say we can also get some of the water we need in the foods we eat. Most fruits and vegetables are more than 80% water. Meats are 50%-60% water. And even bread is about 33% water. Water may be one of the most simple of all chemical substances, but it is the most important substance that we put into our bodies. Water is a kind of chemical substance.
