摘要： It can be concluded from the passage that in the used car market, . A. used cars are generally cheap B. used cars are actually expensive C. used cars are actually brand new D. car buyers are willing to pay a high price for a used car B Certain animals and plants develop characteristics that help them deal with their environment better than others of their kind. This natural biological process is called adaptation. Among the superior characteristics developed through adaptation are those that may help in getting food or shelter, in providing protection, and in producing and protecting the young. That results in the gradual development of more and more organismsthat are better fitted to their environments. Each living thing is adapted to its way of life in a general way, but each is adapted especially to its own distinct class. A plant, for example, depends upon its roots to fix itself firmly and to absorb water and inorganic chemicals. It depends upon its green leaves for using the sun's energy to make food from inorganic chemicals. These are general adaptations, common to most plants. In addition, there are special adaptations that only certain kinds of plants have. Many animals have adaptations that help them escape from their enemies. Some insects are hidden by their body color or shape, and many look like a leaf or a little branch. The coats of deer are colored to mix with the surroundings. Many animals have the ability to remain completely still when an enemy is near. Organisms have a great variety of ways of adapting. They may adapt in their structure, function, and genetics; in their development and production of the young; and in other respects. An organism may create its won environment, as do warm-blooded mammals, which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather. Usually adaptations are an advantage, but sometimes an organism is so well adapted to a particular environment that, if conditions change, it finds it difficult or impossible to readapt to the new conditions.

Suppose that you, a college student of somewhat limited means, are in the market for a used pickup truck. The following ad in a local used car publication catches your eyes.

1993 Ford Ranger, bilk, 4WD,a/c,

AM/FM/cass., showroom condition.

Call 555-1234 after 5 p.m.

This is exactly the kind of vehicle you want, so you call to ask the price. The price you have mentioned over the phone is $2,000 lower than the Price for this model with this equipment listed in a used car guidebook. Instead of being ecstatic (happy), however, you are suspicious (怀疑的).

For many products, when you must pay less than the going rate, you believe you are getting a great deal. This is not necessarily the case for used cars or other durable goods (washing machines and television sets, for example) because with expensive products—or, what is essentially the same thing, products with high replacement costs—you must be particularly careful about getting a “lemon (柠檬),” or a product of substandard（低于标准）quality.

In addition to asking the price, the age of a car —or any other consumer durable—is a factor when you are trying to determine whether a seller is attempting to unload a lemon. While people hold off until they have put many thousands of a car that is “too new” as you would have a car that is “too good” a deal. In fact, you are probably willing to pay a high for a high quality used car. While this price would certainly be acceptable to the seller, the competitive market might not facilitate such trades.

A. a kind of fruit B. a kind of new car

C. a kind of expensive and high-quality car D. a product of inferior quality (劣质)
