Color use in nature
Nature is very colorful, full of different hues（色调）that delight the eye. What makes these colors and why do they exist?
Causes of Colors in Nature
Colors in nature are formed in two ways. Pigments, like the melanin in skin and many animal furs, produce most blacks, browns, reds and yellows. Most plants are green due to chlorophyll（叶绿素）. Other colors are caused by structure, like many greens, blues, and whites. Blue bird’s feathers actually contain black pigment, but their structure causes them to appear blue. The scattering of light by tiny dust particles in the air, viewed against the black background of space, makes the sky look blue too.
Color Use in Plants
Color has a great effect on the survival of plants and animals. Flowers have bright hues and patterns to attract insects. These insects move from one flower to another, making sure seeds are produced. Bees can see colors we cannot, i.e. ultraviolet, and follow these patterns of stripes or dots to the inside of the flower.  
Not only flowers but also fruits use color for the good of the plant. An unripe fruit mixes in with the leaves, but ripe berries contrast, becoming more appealing to the creatures who eat them. Birds are especially drawn to red fruit, and in turn help the plant by broadcasting its seeds.
Camouflage（伪装）in Nature
Many colors and patterns camouflage animals who want to avoid enemies. Some animals have damaging shapes to break up their outline, so an enemy will not recognize them. The eye, a very recognizable animal characteristic, is often disguised by a black stripe or patch. Light color below makes up for the shadow on the underside of many fish, amphibians and mammals.
Some animals even change colors to better camouflage themselves, seasonally like the snowshoe hare.
Warning Coloration and Mimicry（动态伪装）
Warning colors make an animal more visible rather than hidden. These usually indicate a negative aspect of the animal, like the bad taste of a monarch butterfly, smelly smell or painful bite of a bee. Usually black and a contrasting color (white, yellow, orange or red) form a striking pattern in these creatures, and frighten their enemies away. Nature is tricky, though, and sometimes harmless creatures pretend the patterns of harmful ones to scare off animals living on meat too.  
Social Coloration in Nature
Sometimes coloration is important socially. Male birds, typically more colorful, defend their territories and attract females. Eggs may use color and pattern to remain hidden. When they hatch, parents feed the nestlings when they see the bright pattern in their gaping mouths.
Taking a closer look at nature throws light on how color is used in marvelous ways!

Animal Conservation

Many animal and plant species have become extinct（灭绝的）and many more are in critical danger. Finding ways to protect the earth's wildlife and conserve（保护）the natural world they inhabit（居住）is now more important than ever.

Dodo

The Dodo is a classic example of how human caused damage to the earth's biology. The flightless Dodo was native to the Island of Mauritius in the Indian Ocean. It lived off fruit fallen from the island's trees and lived unthreatened until humans arrived in 1505. The easily controlled bird became a source of food for sailors and was attacked by animals introduced to the island by humans such as pigs, monkeys and rats. The population of Dodos rapidly decreased and last one was killed in 1681.

Rhinos

The Rhino (犀牛) horn is a highly prized item for Asian medicine. This has led to the animal being hunted in its natural habitat. Once widespread in Africa and Eurasia, most rhinos now live in protected natural parks and reserves（保护区）. Their numbers have rapidly decreased in the last 50 years, and the animals remain under constant threat from poachers（偷猎者）.

The Giant Panda

The future of the World Wildlife Fund's symbol is far from certain. As few as 1000 remain in the wild． The Chinese government has set up 33 panda reserves to protect these beautiful animals and made poaching them punishable with 20 years in prison. However, The panda's distinct black and white patched coat fetches a high price on the black market and determined poachers still pose（造成）one of the most serious threats to the animals continued existence.

Whales

The International Whaling Commission is fighting to ensure the survival of the whale species. Despite the fact that one-third the world's oceans have been declared whale sanctuaries（保护区）, 7 out of 13 whale species remain endangered． Hunted for their rich supply of oil, their numbers have decreased to just 300. Collisions（碰撞）with ships, poisonous pollution and being caught in fishing nets are other major causes of whale deaths.

Tigers

The last 100 years has seen a 95% reduction in the numbers of remaining tigers to between 5000 and 7000 and The Bali, Javan, and Caspian tigers are already extinct. The South China tiger is precariously close to disappearing, with only 20 to 30 still alive. Like the Rhino horn, tigers’ bones and organs are sought after for traditional Chinese medicines. These items are traded illegally along with tiger skins.

It implies that _______.

       A．The Dodo lacked the ability to protect itself from other animals

       B．Sailors to the Island of Mauritius lived mainly on the Dodo

       C．The Dodo used to be a strong animal that liked fighting.

       D． The Dodo, pigs, monkeys and rats were the natives to the Island of Mauritius

Which group of the following animals has already ceased to exist according to the text?

       A．The Dodo, Rhino and Giant Panda． 

       B．The Rhino, Whale and South China Tiger.

       C．The Rhino, Panda, Whale and Tiger. 

       D． The Dodo and the Bali, Javan, and Caspian tigers.

______ can serve as a cure for certain diseases.

       A．The whale’s rich oil

       B．The panda's black and white patched coat

       C．The Rhino horn and tigers’ bones and organs

       D． The Dodo’s delicious meat

Which of the following statements is NOT true?

       A．The number of South China tigers has reached crisis point.

       B．Many animals are threatened with extinction as a result of human activity.

       C．People hunt for the endangered animals for high profit.

       D． The Whale is the representing mark for the World Wildlife Fund．

Many animal lovers would like to do more to help animals, but aren’t sure where to start or feel like they just don’t have the time. The good news is that there are many simple things you can do to help protect animals.

Think twice before you decide

The decisions you make when it comes to eating meat or other animal products can go a long way toward stopping the killing of animals. Consider eating a vegetarian（素食的） diet. If you aren’t ready to make this change, there are still things you can do. Do not buy animal products from companies known to use practices that go against the law such as using drugs to increase milk production in cows.

Help get the word out

Getting the word out about the problems faced by animals can be as easy as putting up a notice on your car. Also, talk to your friends and family members about important issues that are related to animals. Give some simple advice to a friend with a new pet about the serious pet over-population problem we’re facing. Turn to some books on the subject if you are not so clear about the advice you give your friend.

Write a letter

We’ve all heard the saying, “ The pen is more powerful than the sword”. Put this idea to the protection of animals. If a company has practices or rules that are harmful to animals, write them a letter to let them know you are angry about them, and that you won’t buy their products until they make some changes. Write letters to state and local legislators（立法者） to let them know how important it is that they support legislation that protects animals. Make them know that their actions will have a great effect on your vote.

Be more loving

If you’re considering adding a dog or a cat to your family, think about getting one from a homeless-animal house rather than buying a pet. There are many wonderful animals just waiting for a home. By taking back an animal from there, you will be helping in the fight against pet over-population, as well as giving your money to those who are responsible for taking care of pitiful animals.

Let your actions be an example to others

It may sound simple ,but one of the best ways to help animals is to let your actions speak to the world. You should do the following things first by yourself: Treat all living creatures with respect. Care about your pets and look after them well. Avoid (避免)entertainment places that use animals to perform. Support legislation （立法）that protects animals. All of these things set an example for others to follow.
