Causes for Juvenile Delinquency
Juvenile Delinquency refers to criminal acts committed by children or teenagers, specifically anyone below the age of eighteen. These crimes hurt society and the children themselves.
There are many factors that cause juvenile delinquency. Some children want to test their parents'or society's limits. Sometimes juvenile crimes happen because of a lack of rules and supervision. For example, many times children commit crimes after school and while their parents are at work.
Additionally, mental illness and substance abuse are main factors. 15-20% of juveniles convicted of crimes have serious mental illnesses, when the range of mental illnesses widens， the percentages increase to 30-90%. Also, many people believe, a child's environment and family are greatly related to their juvenile delinquency record. For example, the dynamics of a family can affect a child's delinquency rate. Poverty level is another factor.
Finally, another cause could be the relationships a child grows in school or outside of school. A positive or negative friendship can influence the chances of children becoming delinquents. Peer pressure is also at play. Relationships and friendships can lead to gangs, these are major factors in violent crimes among teens. These are just some of the causes of juvenile delinquency.

Droplets and ice crystals behave somewhat like dust in the air made visible in a shaft(束) of sunlight. To the casual observer, dust seems to act in a totally random fashion, moving about wildly without fixed direction. But in fact dust particles are much larger than water droplets and they finally fall. The cloud droplet of average size is only 1/2,500 inch in diameter. (78)It is so small that it would take sixteen hours to fall half a mile in perfectly still air, and it does not fall out of moving air at all. Only when the droplet grows to a diameter of 1/125 inch or larger can it fall form. the cloud. The average raindrop contains a million times as much water as a tiny cloud droplet. The growth of a cloud droplet to a size large enough to fall out is the cause of rain.
What is the main topic of the passage？
A．The mechanics of rain.
B．The climate of North America.
C．How gravity affects air current.
D．Types of clouds.
？？？？？？You might think that “global warming” means nothing more than a rise in the world’s temperature. But rising sea levers caused by it have resulted in the first evacuation of an island nation -the citizens of Tuvalu will have it leave their homeland.？？？？
？？？？During the 20th century, sea level rose ？？8-12 inches. As a result, Tuvalu has experienced lowland flooding of salt water that has polluted the country’s drinking water.？？
？？Paani Laupepa, a Tuvaluan government official, reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years. Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.？？
？？Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol,an international agreement calling for industrialized nations to reduce their green house gas emissions（导致温室效应的气体排放）,which are a main cause of global warming. “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years.” Laupepa told the BBC.？？
？？Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries.？？
？？Tuvalu is not the only country that is vulnerable （易受影响的）to rising sea levels. Maumoon Gayoon, president of the Maldives, told the United Nations that global warming has made his country of 311,000 an “endangered nation”.
？？The text is mainly about_________.？？？？
A.rapid changes in earth’s temperature

According to scientists，the DIRECT cause of more and fiercer storms is__________.A.greenhouse gas emissions in industrialized nations
B.higher surface water temperatures of the sea
C.continuous global warming
D.rising sea levels
One important cause of the generation gap is the opportunity that young people have to choose their own ways of life.In a more traditional society, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and like, and often to continue the family jobs.In our society, young people often travel great distances for their education, move out of the family at an early age, marry or live with people whom their parents have never met, and choose jobs different from those of their parents.
In our society, parents often expect their children to do better than they did, to find better jobs, to make more money and to do all the things that they were unable to do.Often, that is another cause of the gap between them.Often, they discover that they have very little in common with each other.
Finally, the speed at which changes take place in our society is the third cause of the gap between the generations.In a traditional culture, senior people are valued for their knowledge, but in our society the knowledge of a lifetime may become out of date.The young and the old seem to live in two very different worlds, separated by different skills and abilities.No doubt, the generation gap will continue in American life for some time to come.
