We can see how the product life cycle works by looking at the introduction of instant(速溶) coffee.When it was introduced, most people did not like it as well as "regular" coffee, and it took several years to gain general acceptance(introduction stage).At one point, though, instant coffee grew rapidly in popularity, and many brands were introduced(stage of rapid growth).After a while, people became attached to one brand and sales leveled off(stage of maturity).Sales went into a slight decrease when freeze-dried coffees were introduced(stage of decline).
The importance of the product life cycle to marketers is this: Different stages in the product life cycle call for different strategies.The goal is to extend product life so that sales and profits do not drop.One strategy is called market modification.It means that marketing managers look for new users and market sections.Did you know, for example, that the backpacks that so many students carry today were originally designed for the soldiers?
Market modification also means searching for increased usage among present customers or going for a different market, such as senior citizens.A marketer may re-position the product to appeal to new market sections.
Another product extension strategy is called product modification.It involves changing product quality, features, or style to attract new users or more usage from present users.American auto manufacturers are using quality improvement as one way to regain world markets.Note, also, how auto manufacturers once changed styles eagerly from year to year to keep demand from falling.

Millions of years ago dinosaurs (恐龙) lived on the earth. In the days of dinosaurs the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry. and the forests there died. Then dinosaurs could not find enough to eat. This must be one reason why dinosaurs died out.
We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs. There may be other reasons that we don’t know about yet. Scientists are trying to make more discoveries about dinosaurs.
Dinosaurs were of many sizes and shapes (形状). Some were as small as chickens, while some were about 90 feet long.
There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animal’s footprints (足迹) that fight did take place.
