    Throughout the world, clothing has many uses. It is used to provide protection from the elements. It is also worn to prevent others from seeing specific parts of one's body. However, the parts of the body that must be covered vary widely throughout the world. Some clothing is worn to

provide supernatural protection. Wearing a lucky shirt to take an exam is calling for supernatural assistance.

    People in all cultures use clothing and other forms of bodily decoration to communicate status,intentions and other messages. In North America, we dress differently for business and various leisure activities. North American women usually are much more knowledgeable of and concerned

With little difference in messages communicated by clothes than men. At times, this leads to silly mistakes of interpretation（解释） of female intentions on the part of men. Of course. clothing styles also are intended to communicate messages to members of the same gender（性别）．

    Long before we are near enouth to talk to someone, their appearance tells their gender, age,economic class. and often even intentions. We begin to recognize the important cultural clues at an early age. The vocabulary of dress that we learn includes not only items of clothing but also

hairstyles, jewelry, and other body decoration. In most cultures, however, the same style of dress communicates different messages depending on the age, gender. and physical appearance of the individual wearing it.

   Putting on certain types of clothing can change your behavior and the behavior of others towards you. This can be the case with a doctor's white lab coat, or an army uniform. Most uniforms are clearly symbolic so that they can rapidly and unmistakably communicate status. For instance. the

strange hairstyle and clothing of the English "punks" are essential aspects of their uniforms.

   There are many forms of body decoration other than clothes that are used around the world to send messages. These include body and hair paint, and even body deformation. When doctors put braces on teeth, they are actually doing the same thing - deforming or reforming a part of the body

to make it more attractive.

1．_______

Humanity uses a little less than half the water available worldwide．Yet occurrences of shortages and droughts are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies．Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis．

2．_______

But that doesn’t have to be the outcome．Water shortages do not have to trouble the world----if we start valuing water more than we have in the past．Just as we began to appreciate petroleum more after the 1970s oil crisis, today we must start looking at water from a fresh economic perspective．We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want．

3．_______

Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value．This means charging a fee for the water itself as well as for the supply costs．

4．_______

Governments should also protect this resource by providing water in more economically and environmentally sound ways．For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions（凹地） and pumping it to nearby cropland．

5．________

No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use．Rather than spread control among hundreds of even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate water policy．

With the development of Internet, ________ communication is done by regular mail.
