     The traditional distinction between products that satisfy needs and those satisfy wants is no longer

adequate to describe classes of products. In today's prosperous societies, the distinction has become

unclear because so many wants have been turned into needs. A writer, for instance, can work with paper

and pencils. These are legal needs for the task. But the work can be done more quickly and efficiently

with a word processor. Thus a computer is soon viewed as a need rather than a want.

     In the field of marketing, consumer goods are classed according to the way in which they are

purchased. The two main classes are convenience goods and shopping goods. Two lesser types are

specialty goods and unsought (主动提供的) 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) should 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, 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 without enough thinking; someone has a sudden desire for an ice cream

sundae(圣代) 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 before making a decision. Buying an automobile is often done this way.

     Shopping goods fall into two classes; those that are recognized 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 essentially different

include clothing, furniture, and dishes. Quality, style and fashion will either take precedence(优先) over

price, or they will not matter at all.

1. It can be learned from the first paragraph that ______.

A. a writer needs a word processor

B. needs and wants can't be separated clearly

C. the way to distinguish the products is unimportant

D. a computer is a need rather than a want

2. The example of wine is used to illustrate that ______.

A. goods are classified differently in different countries

B. the types of the product lie on the people rather than its nature

C. Frenchmen often drink but Americans sometimes do

D. one product may belong to many types

3. Staples are items that ______.

A. are convenient to purchase

B. are purchased without enough thinking

C. people "want but don't need"

D. people are in constant need of

4. Shopping goods that are considered as basically the same are those that ______.

A. consumers don't care where to buy them

B. consumers spend much time searching for

C. satisfy similar needs of the consumer

D. can be found in nearly every shop
