A piece of equipment that uses the sun is a good way to dry food. The simplest solar dryer is called the direct has a cover made of clear glass or plastic. When the sun shines into the box， heat is produced. The heat is trapped inside the box and cannot escape back through the cover. The heat dries the food. The solar dryer works better if the sides of the box are black. This is because dark colors hold heat while light colors reflect it. One way to make the sides black is to use wood that has been blackened by fire. The box can be made of almost any material such as wood and metal. The surface on which the food is placed should permit air to enter from below and pass through to the food. A surface made of wires with small square openings works very well. You should use wire with the largest openings that do not allow the food to fall through. Air that es in from below the wire surface will also carry away water evaporated(蒸發(fā) )from the food as it dries. A direct dryer will dry most vegetables in two173。and173。one173。half to four hours at temperatures from 43℃ to 63℃. Fruits take longer ， from four to six hours at the same temperatures. Solar food drying is fast， safe and low173。cost. Solar dried food tastes delicious and looks good.

Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms. In fact, it is impossible to estimate the number of people in the world who have acquired an adequate(足夠的 ) working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation. The main reason for the widespread demand for English is its present173。day importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport munications, international conferences, and the spread of information over the radio and television works of many nations. It is a language of wider munication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal munication in such matters as government, merce, industry, law and education as well as for international munication and for entrance to the scientific and technological developments in the West. 32． What would be the best title for this passage?
