be an optimist (乐观者), a leader, and an active person who enjoys life, people and excitement.Do you prefer grays and blues？ Then you are probably quiet, shy and you would rather follow than lead.You tend to be a pessimist.At least, this is what psychologists (心理学家)tell us, and they should know, because they have been seriously study ing the meaning of color preference, as well as the effect that colors have on human beings.They tell us among other facts, that we do not choose our favorite color as we grow up — we are born with our preference.If you happen to love brown, you did so,as soon as you opened your eyes, or at least as soon as you could see clearly.

Color does influence our moods (情绪)― there is no doubt about it.A yellow room makes most people feel more cheerful and more relaxed than a dark green one; and a red dress bri ngs warmth and cheer to the saddest winter day.On the other hand, black is depressing.A black bridge over the Thames River, near London, used to be the scene of more suicides than any other bridge in the area — until it was repainted green.The number of suicide attempts immediately fell sharply; perhaps it would have fallen even more if the bridge had been done in pink or baby blue.

Light and bright colors make people not only happier but also more active.It is an established fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or gray.

Passage Two

Questions 26 to 30 are based on the following passage.

Certain animals and plants develop characteristics(特性)that help them cope with their environment better than others of their kind. This natural biological process is called adaptation(适应性). 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 evolution of more and more organisms that 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 for adapting. They may adapt in their structure，function，and genetics(遗传素质)；in their development and production of the young；and in other respects. An organism may create its own 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.
