The Coalition for the Homeless is an organization that seeks to address the needs of the homeless population in the United States．It is a network of offices, some of which provide food and houses for the homeless population．and some of which fight for the passing of laws that would give every American the right to a place to call home．According to the Coalition’s studies, of over two hundred million people living in the United States, up to three million are homeless—and the number is still growing since the late 1970s, fast rising house prices, large cuts in government supported housing programs, and economic recession have made it impossible for many Americans to meet housing costs．Sadly, this has resulted in a number of persons being forced to leave their homes and or unable to find new affordable homes．According to another research．families with children appear to be the fastest-growing part of the homeless population, making up 39% of it．The old idea of a homeless person, that of the single man who gets drunk all the time, is no longer true．A much larger part of the population now finds itself homeless．Even worse, once a person becomes homeless, he often finds it impossible to find a job, since most employers require anyone who wants a job from them to provide a home address on a job application

Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest.

Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes (纬度). To achieve giant size, a tree needs three things: the right place to establish its seedling, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees.

In some parts of the world, populations of big trees are dwindling(逐渐变少) because their seedlings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear.

Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. “During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic (新陈代谢) rate increases,” explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth.

The Clarks’ theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization(不稳定) of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions.

Besides, big trees face threats from elsewhere.

As we all know ,trees are important to our life. They provide us with food, wood and most importantly, oxygen. Now there is one more thing we can add to this list—blocking out harmful bacteria in water.

The discovery was made by some scientists and high school students who were seeking for a natural water filter(过滤器)—one that could help people in developing countries that don’t have access to modern water systems.

The researchers, led by Rohit Karnik, a professor ,decided to turn to trees for help because they were able to allow liquid to flow through while blocking out air bubbles(气泡）.

They began by cutting 1.5-inch-wide sections of tree bark from the branch of a white pine tree. The researchers then tested the wood’s filtering ability by pouring water containing red dye particles(染料颗粒)of different sizes through. To their surprise, they found it was effective in trapping all the particles. Encouraged, the team did another experiment, this time with water containing bacteria. Sure enough, the bark held back 99%of the bacteria, allowing only 1% to flow through.

Mr. Karnik said the bark was able to filter water containing much smaller particles. This means that it can be used to get rid of most of the bacteria. However, what troubles them is that tree bark cannot hold back viruses, which tend to be much smaller.

Though the experiment is successful, we must remember one thing—the bark only works when damp. This means that before this natural filter can be put to practical use, the researchers will have to figure out how to keep the bark damp, or find a way to keep the bark’s great filtering ability even when it’s dry.

But the study is not done. The researchers plan on testing other types of trees, including those flowering trees. They think those may be more effective in trapping smaller particles and even viruses.

1.How will the discovery affect the world?

A. No harmful bacteria will be found in water.

B. There will be no water pollution around the world.

C. More pine trees will be planted around the world.

D. Clean water will be more accessible in developing countries.

2.What problem troubles the researchers when using the trees bark as a water filter?

A. Viruses cannot be prevented.

B. Tree bark should be wet.

C. It’s hard to remove air bubbles.

D. Not all bacteria can be held back.

3.Why does the team plan to do other experiments?

A. To find other natural water filters.

B. To improve the filtering ability of other trees.

C. To find a way to keep the bark wet.

D. To test the filtering ability of other trees.

4.In which column of a newspaper can we read this text?

A. Culture.　　 B. Science.

C. Lifestyle.　　 D. Society.

From the beginning of human history, wild animals provided food, clothing and sometimes medicine for man. We may not depend as much on wild animals now. But we hear about them every day. Americans use the names of animals in many ways. Automobile manufacturers and gasoline companies especially like to use big cats to sell their products. They like lions, tigers and wildcats. When Americans say wildcat, they usually mean a lynx, an ocelot or a bobcat. All these cats attack quickly and fiercely. So wildcats represent something fast and fierce.

An early American use of the word wildcat was quite different. It was used to describe members of Congress who declared war on Britain in 1812. A magazine of that year said the wildcat congressmen went home. It said they were unable to face the responsibility of having involved their country in an unnecessary war.

Wildcat also has been used as a name for money in the 1800s. At that time, some states permitted banks to make their own money. One bank in the state of Michigan offered paper money with a picture of a wildcat on it. Some banks, however, did not have enough gold to support all the paper money they offered. So the money had little or no value. It was called a wildcat bill or a wildcat banknote. The banks who offered this money were called wildcat banks. A newspaper of the time said those were the days of wildcat money. It said a man might be rich in the morning and poor by night.

Wildcat then was also used for an oil well or gold mine that had almost no oil or gold in it. Dishonest developers would buy such property. Then they would sell it and leave town with the money. The buyers were left with worthless holes in the ground. Today, wildcat oil wells are in areas that are not known to have oil.

1.What is the main idea of the passage?

A. Wildcats and their stories.    B. Wildcats and their characters.

C. Varieties of animal species.    D. Relationship between animals and humans.

2. The underlined words "a lynx, an ocelot or a bobcat" in Paragraph 1 may refer to "__________".

A. gasoline companies       B. automobile manufacturers

C. brands of automobile                         D. names of wildcats

3.Which of the following would people like to have or trust according to the passage?

A. Wildcat congressmen.            B. Wildcat oil wells.

C. Wildcat banks.                D. Wildcat cars.

4.It can be inferred that during the days of wildcat money__________.

A. people couldn't buy anything with the money

B. people complained and suffered a lot

C. the rich invested too much on oil wells

D. people didn't know how to save money
