要生成现今栖居在地球上的生物需要亿万年的时间──在这漫长的时间里，生物不断发展进化，种类越变越多，达到一种同其环境相适应、相平衡的状态。而环境一丝不苟地塑造和引导它所供养的生物，这环境既包含有利生物生长的成分，又包含有害的成分。某些岩石放射出危险的射线；即便在一切生物从中取得能量的日光中，也包含有伤害力的短波射线。经过一定的时间──不是过了若干年，而是过了千百年，生物适应了环境，达到了平衡。时间是最基本的因素。但在现代世界里人们没有时间去适应世界的急速变化。
伴随着人类急躁轻率的步伐胜过了自然界稳健的步履，事物很快发生变化，新情况急剧不断地产生。如今辐射已不仅仅是地球上出现生命之前便存在的岩石隐秘射线、宇宙射线以及太阳紫外线，它更是人类拨弄原子的奇异产物。同样，逼迫生物与之适应的化学物质不再只是从岩石上冲刷出来由河流带入海洋的钙、二氧化硅、铜以及其它矿物质，它们还有人类聪明才智所创造的人工合成物，在实验室里配制而成，在自然界找不到与它们相似的东西。
下列说法不正确的一项是（）
A.人类对环境的改变令人不安
B.人类无法适应环境变化
C.人类的急躁轻率使新情况不断产生
D.人类随着环境的变化而变化。
在过去的四分之一世纪里，这种力量不仅增大到了令人不安的程度，而且其性质也发生了变化。这句话中“这种力量”具体是指什么？（）A．人类改变大自然
B．人类改造大自然
C．人类善待大自然
D．人类影响大自然
对文意的理解，正确的一项是（） A、人类对环境最可怕的破坏是用危险甚至致命的物质对空气、土地、河流和海洋的污染。这种污染多是无法救治的。
B、如今地球上幅射岩石隐秘射线、宇宙射线以及太阳紫外线，逼迫生物与之适应的化学物质有钙、二氧化硅、铜以及其它矿物质。
C、人类所导致的环境污染不仅是已经侵入到生物组织之中，改变了“生物的根本性质”，更为严重的是存在于生物赖以生存的世界。
D、化学药品是导致环境污染的元凶之一，但因其广泛应用大大提高了农作物的产量，正为人们所推崇。

Judging from countless media reports in newspapers from coast to coast, it would surely seem that we have finally got a handle on the Nation’s crime problem. The most recent FBI release of crime statistics for 1995 revealed a welcome drop in violent crime, including an 8 per cent decline in homicide. (46. After four straight years of lower crime levels, some crime experts and law enforcement officials have even dared boldly to suggest that we’re winning the war against crime.)
Though recent trends are encouraging, at least superficially, there is little time to celebrate these successes. It is doubtful that today’s improving crime picture will last for very long. Most likely, this is the calm before the crime storm. (47. While many police officials can legitimately feel gratified about the arrested crime rate — better that it be down than up — there is much more to the great crime drop story.) Hidden beneath the overall drop in homicide and other violent crime is a soaring rate of mayhem among teenagers.
(48. There are actually two crime trends ongoing in America — one for the young and one for the mature, which are moving in opposite directions.) Since 1990, for example, the rate of homicide committed by adults, ages 25 and older, has declined 18 per cent as the baby boomers matured well past their crime prime years. At the same time, however, the homicide rate by teenagers, ages 14 to 17, has increased 22 per cent. Even more alarming and tragic is that over the past decade, the homicide rate at the hands of teenagers has nearly tripled, increasing 172 percent from 1985 to 1994.
Therefore, while the overall U.S. homicide rate has indeed declined in recent years, the rate of juvenile murder continues to grow, unabated by the spread of community policing, increased incarceration, and a variety of other popular crime-fighting strategies. (49. In the overall crime mix, the sharp decline in crime among the large adult population has eclipsed the rising crime rate among the relatively small population of teens.)
Trends in age-specific violent arrest rates for homicide, rape, robbery, and aggravated assault confirm the patterns found in homicide statistics. Teenagers now exceed all age groups, even young adults, in their absolute rate of arrest for violent crime overall. Conventional wisdom in criminology — that young adults generally represent the most violence-prone group—apparently needs to be modified in light of these disturbing changes.
The causes of the surge in youth violence since the mid-1980s reach, of course, well beyond demographics. (50. There have been tremendous changes in the social context of crime over the past decade, which explain why this generation of youth—the young and the ruthless—is more violent than others before it.) Our youngsters have more dangerous drugs in their bodies, more deadly weapons in their hands, and a seemingly more casual attitude about violence. It is clear that too many teenagers in this country, particularly those in urban areas, are plagued with idleness and even hopelessness.
