record of the weather even further back.

It's clear that a tree would grow best in a climate with lots of sunlight and rainfall. It is also expected that little sunlight or rainfall would limit the growth of a tree. The change from a favorable (有利的) to an unfavorable climate can be reading the tree rings in tree trunk. To find out the weather of ten years ago，count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings，then we are sure that lots of sunny and rainy weather happened. If the rings are close together，then the climate was bad for the tree.

Studying tree rings is important not only for the history of the weather，but also for the history of man. In a place of New Mexico you can find only sand-no trees and no people. However，many centuries ago a lot of people lived there. They left suddenly. Why？

A scientist studied the dead tree rings which had grown there. He decided that the people had to leave because they had cut down all the trees. Trees were used to make fires and buildings. So, after the people cut down the trees，they had to move.

Law enforcement agencies are beginning to show interests in the effect of atmospheric conditions on behavior. Every year, the FBI's Uniform. Crime Reports provide break-downs of the crime rates by month and season of the year. Both monthly and seasonal variations are considered to reflect the varying influence of temperature, precipitation, humidity, length of daylight, and a number of other climatological factors.

Various studies find relationships between specific climatological conditions and crime. Rising temperature is generally accompanied by increase in aggression and violent crime. On the other hand, high humidity appears to reduce the incidence of physical activity and aggression. Rain, cloud cover, and other forms of inclement weather are associated with lower levels of property crimes and increased depression.

Our study showed that low humidity has the most widespread influence on all types of crime studied. The analysis also shows that as humidity increase the level of crime decreases. Temperature also has a great effect. Increasing temperature fails to influence the number of nighttime burglaries/larcenies, but it does increase the other crime categories. Burglaries/larcenies (day and night) and daytime assaults also tend to increase along with cloud cover. Except for wind speed and barometric pressure with regard to daytime assaults, the remaining weather factors have virtually no influence on the levels of crime.

Individuals who respond with criminal behavior. to weather change or weather extremes may be controllable by administering drugs that offset these influences. Electrical stimulation of pleasure centers in the brain may someday be a feasible countermeasure to aggressive stimuli due to increased temperature or other weather variables.

Changing or manipulating the weather is one possible means of attacking a weather crime interaction. This approach may not be feasible due to the many relationships between weather/ climate and the rotation of the earth. Minor changes may be possible such as regulation of rainfall of sky cover. On the other hand, temperature control may be impossible.

More research is needed to assess and clarify the relationship between crime and the various climatological factors. Once this is accomplished, it will be necessary to devise more accurate means of forecasting the weather, counteracting the effects of weather on human behavior, and controlling the environment, or identifying other approaches to the problem.

People are likely to be very active and aggressive

A．when it is rainy and cloudy.

B．as humidity increases.

C．when there is little moisture.

D．as temperature decreases.
