In ancient Mexico there were many clearings in the forest. In each clearing was a village with fields of different crops around it. The Maya cut down trees with stone axes and planted seeds by digging holes in the ground with pointed sticks. A farmer was able to grow crops that produced food for several people. But not every Maya had to be a farmer. Some were cloth makers, builders, or priests. The Maya believed in many gods. The people built large temples to honor their gods. Skillful workers built cities around these temples. It was difficult to construct these cities, because they had no horses to carry the heavy stone needed. Workers had to carry the building materials themselves. Today, many of these ancient Mayan cities and temples are still standing. Measuring time was important to the Maya, so they developed a system for measuring it accurately. Farmers needed to know when to plant and harvest their crops. Mayan priests made a system to keep track of time. They wrote numbers as dots (...) and bars (- ). A dot was one and a bar was five. The Mayan priests studied planets. They made a calendar from what they learned. The year was divided into. 18 months of 20 days each with five days left over. The Mayan calendar was far more accurate than the European calendars of the time. Around the year 800, the Maya left their villages and beautiful cities, never to return. No one knows why. They may have died from an infectious disease. They may have left because the soil could no longer grow crops. Archaeologists are still trying to find the lost secrets of the Maya. They are still one of our greatest mysteries. This article may be taken from ______. A．a magazine B．a literature book C．an art book D．a historical book

In the field of marketing, consumer goods are classed according to the way in which they are purchased. The two main categories are convenience goods and shopping goods. Two lesser types are specialty goods and unsought goods. It must be emphasized that all of these types are based on the way shoppers think about products, not on the nature of the products themselves. What is regarded as a convenience item in France(wine, for example) may be a specialty goods in the United States. People do not spend a great deal of time shopping for such convenience items as groceries, newspapers, toothpaste, razor blades, aspirin, and candy. The buying of convenience goods may be done routinely, as some families buy groceries once a week. Such regularly purchased items are called staples. Sometimes convenience products are bought on impulse: someone has a sudden desire for an ice cream on a hot day. Or they may be purchased as emergency items. Shopping goods are items for which customers search. They compare prices, quality, and styles, and may visit a number of stores be fore making a decision. Buying an automobile is often done this way. Shopping goods fall into two classes: those that are perceived as basically the same and those that are regarded as different. Items that are looked upon as basically the same, include such things as home appliances, television sets, and automobiles. Having decided on the model desired, the customer, is primarily interested in getting the item at the most favorable price. Items regarded as inherently different include clothing, furniture, and dishes. Quality, style, and fashion will either take precedence over price, or they will not matter at all. Specialty goods have characteristics that impel customers to make special efforts to find them. Price may be no consideration at all. Specialty goods can include almost any kind of product. Normally, specialty goods have a brand name or other distinguishing characteristics. Unsought goods are items a consumer does not necessarily want or need or may not even know about. Promotion or advertising brings such goods to the consumer's attention. The product could be something new on the market as the Sony Walkman once was or it may be a fairly standard service, such as life insurance, for which most people will usually not bother shopping. A word processor can be looked on as satisfying a need rather than a want if ______. A．it is used at home to do paper work B．it is used by a writer to type a novel C．it becomes the only means to an end D．a writer does not want to use it
