Water is one of the most important natural resources in the world.Everywhere, water use is

Water is one of the most important natural resources in the world.

Everywhere, water use is【61】. Humans already use fifty-four percent of all the【62】 water in rivers, lakes and underground. There are some estimates that this【63】will reach seventy percent by 2005.

Fresh water is necessary for life on Earth. People need water for【64】activities and to produce food. Water also is important for energy production and health of Earth's environmental systems.

The United Nations is organizing a【65】of events to increase concern【66】water issues. UN officials have【67】2003 the International Year of Fresh Water. A goal of the【68】is to build support for policies to use water more【69】.

Another goal is to get more people to use water in a way【70】will not hurt environment. The world population is more than six-thousand-million people. More than one-thousand-million【71】safe drinking water. More than two-thousand-million【72】 from diseases【73】to dirty water. And, more than two-thousand-million live without waste-treatment systems.

Water was one of the issues discussed at the UN Millennium Summit two years ago. Leaders said they would work to【74】the number of people without safe drinking water in half by 2015.

Nitin Desai directs the UN Office for Economic and Social Affairs. He says success【75】 these goals will require major changes in the ways people use water.

Next month, the World Water Forum will meet in Kyoto, Japan. Officials plan to【76】the first UN report【77】world water development. This report will examine the world's water problems.【78】it will offer suggestions on ways to meet future water demands. Experts say international reaction【79】the UN report will be an important test of the political desire to solve the water【80】.

Most dictionaries will tell you a number of【21】about a language. There are three things in
particular that【22】important. These three things are spelling, pronunciation, and meanings.

The first and most obvious thing is that a dictionary will【23】you the spelling of a word. If you' re not sure about the spelling of a word, you can try to find the correct spelling in a dictionary. Words are listed in alphabetical order--a, b, c, and so on .For example, on a dictionary page the word "poor" p, o, o, r--comes before "poverty"--p, o, v, e, r, t, y and the word "poverty" comes【24】the word "power'--p, o, w, e, r. The words are always given in alphabetical Order.

The second thing a dictionary will tell you is【25】. Most dictionaries give the pronunciation of a word in a special kind of alphabet. This special alphabet is called a phonetic, or sound alphabet. The phonetic spelling will tell you generally【26】a word is pronounced. There are a few different phonetic alphabets. Many dictionaries use the International Phonetic Alphabet to show pronunciation.

The【27】thing a dictionary will tell you is the meanings of words. You can【28】a word and find out what it means. Many words have more than one meaning, and a good dictionary will ex plain all of the word' s meanings. For example, in English the common word" get" has over 20 different meanings. The meaning, of course,【29】the sentence in which the word' is used.

These three things--spelling, pronunciation, and meanings--are some of the important【30】that you learn from dictionaries.

Fifty years ago, most people lived in rural areas. But the world has changed. In the near
future, more than half of all people will live in cities for the first time in history.

City life is not always a bad thing, but many experts worry about this process of urbanization (城市化 ). A new report says that process is having a huge effect on human health and the quality of the environment. Of the three billion people who live in cities now, the report says, about one billion live in unplanned settlements. These are areas of poverty, slums that generally lack basic services like clean water, or even permanent housing. More than 60 million people are added to cities and surrounding areas each year, mostly in slums in developing countries. The international community has been too slow to recognize the growth of urban poverty. Policy makers need to increase investments in education, health care and other areas.

The report talks about some successful efforts by local governments and community groups. For example, it says in Columbia, engineers have created a bus system that has helped reduce air pollution and improve quality of life.

The link between urban poverty and the environment is serious, but governments also need to consider why people are moving out of rural areas. Climate changes, droughts, floods—there are many reasons forcing people to leave their farm land.

The two issues of poverty reduction and the environment have existed side by side, but rarely have they connected—until now. Governments are starting to understand that environmental collapse is not a natural cost of economic development. Instead, it is hurting the possibility for growth.

The main idea of the passage is about ______.

A.urbanization and its effects

B.a huge effect of human

C.economic development

D.the environment

At picnics, ants are pests. But they have their uses. In industries such as mining, farming and forestry, they can help gauge the health of the environment by just crawling around and being antsy.

It has been recognized for decades that ants—which are highly sensitive to ecological change—can provide a near-percent barometer of the state of an ecosystem. Only certain species, for instance, will continue to thrive at a forest site that has been cleared of trees. (41) And still others will move in and take up residence.

By looking at which species populate a deforested area, scientists can determine how "stressed" the land is. (42) Ants are used simply because they are so common and comprise so many species.

Where mine sites are being restored, for example, some ant species will recolonize the stripped land more quickly than others. (43) Australian mining company Capricorn Coal Management has been successfully using ant surveys for years to determine the rate of recovery of land that it is replanting near its German Creek mine in Queensland.

Ant surveys also have been used with mine-site recovery projects in Africa and Brazil, where warm climates encourage dense and diverse ant populations. "We found it worked extremely well there," says Jonathan Majer, a professor of environmental biology. Yet the surveys are perfectly suited to climates throughout Asia, he says, because ants are so common throughout the region. As Majer puts it: "That's the great thing about ants."

Ant surveys are so highly-regarded as ecological indicators that governments worldwide accept their results when assessing the environmental impact of mining and tree harvesting. (44)

Why not? Because many companies can't afford the expense or the laboratory time needed to sift results for a comprehensive survey. The cost stems, also, from the scarcity of ant specialists. (45)

[A] This allowed scientists to gauge the pace and progress of the ecological recovery.

[B] Yet in other businesses, such as farming and property development, ant surveys aren't used widely.

[C] Employing those people are expensive.

[D] They do this by sorting the ants, counting their numbers and comparing the results with those of earlier surveys.

[E] The evolution of ant species may have a strong impact on our ecosystem.

[F] Others will die out for lack of food.

[G] Gretaceous ants shared a couple of wasp-like traits together with modern ant-like characteristics.
