Birds are the only animals with feathers, although some other animals, such as insects and bats, also have wings.Nearly all birds can fly, and even flightless birds, such as ostriches (鸵鸟), penguins, evolved from flying ancestors.

Birds are found worldwide in many habitats.They can fly over some of the highest mountains on earth as well as both of the earth’s poles, dive through water to depths of more than 250m, and occupy habitats with the most extreme climates on the planet, including arctic tundra (冻土地带) and the Sahara Desert.Certain kinds of seabirds are commonly seen over the open ocean thousands of kilometers from the nearest land, but all birds must come ashore to raise their young.

Highly developed animals, birds are sensitive and responsive, colorful and graceful, with habits that excite interest and inquiry.People have long been fascinated by birds, in part because birds are found in the same habitats in which humans live.And like people, most species of birds are active during daylight hours.Humans find inspiration in birds’ capacity for flight and in their musical calls.Humans also find birds useful---their flesh and eggs for food, their feathers for warmth, and their companionship.Perhaps a key basis for our friendliness with birds is the similarity of our sensory worlds: Both birds and humans rely more heavily on hearing and color vision than on smell.Birds are useful indicators of the quality of the environment, because the health of bird populations mirrors the health of our environment.The rapid decline in birds populations and the accelerating extinction rates of birds in the world’s forests, grassland, wetlands, and islands are therefore reasons for great concern.

The Peppered Moth, a kind of insect(昆虫), is found in England. It is light brown in colour and likes to settle(栖息) on trees which are also light brown. This makes the moth difficult to be seen and birds are less likely to notice and eat it.
But with the development of industry(工业) , smoke from factories began to reach the trees where the moth settled. It made the trees blacker. Then something very strange took place: in industrial areas, the Peppered Moth began to change colour. It became darker as well. Though the change took several years, some scientists soon notice that newly-born moths were a little darker than usual.
A scientist with the name Kettlewell decided to make a careful study of this phenomenon(现象). He marked some of the light moths and some of the darker ones, and set them free in the woods near Bermingham, an industrial city. Later, he recaptured(重新捕获) as many as the marked moths as possible. The results were as follows.

 
light moths
darker moths
Moths set free
201
601
moths recaptured
34(16%)
206(34%)
Kettlewell's research (研究) was done in the early 1950s. Soon afterwards Britain introduced new laws to reduce smoke and factory pollution.
Can you imagine what would happen to the Peppered Moth as the air became cleaner again?
【小题1】The Peppered Moth began to change its colour in industrial areas because         .
A.it itself liked to
B.it could be like the colour of its living-place

【小题2】From the results of Kettlewell's research, we can see that       .
A.many more of the light moths were killed or eaten
B.more than one-fifth of the light moths was not killed
C.three times as many dark moths were kept safe as light ones
D.more dark moths were killed in industrial areas
【小题3】As the air became cleaner,        .
A.the number of the light moths became larger
B.the total number of the light moths remained unchanged
C.there were more of the darker moths and fewer of the light ones

Secondhand smoke isn’t just a health threat to people.It can also hurt dogs and cats,veterinarians say.
According to the Centers for Disease Control and Prevention,more than 126 million Americans who don't smoke are exposed to secondhand smoke in their homes,vehicles,workplaces,and public places.This exposure causes thousands of lung cancer and heart disease deaths among nonsmokers every year,according to the California Environmental Protection Agency.
“Making the leap from the effects of secondhand smoke on humans to their effects on pets isn't a big one,” says veterinarian (兽医专家) Carolynn MacAllister of Oklahoma State University.
“There have been a number of scientific papers recently that have reported the significant health threat secondhand smoke poses to pets,” MacAllister said.“Secondhand smoke has been associated with oral cancer and lymphoma in cats,lung and nasal cancer in dogs,as well as lung cancer in birds.”
Studies have also shown that dogs living in a smoking household are susceptible to cancers of the nose and sinus area,particularly if they are a long-nosed breed,because their noses have a greater surface area that is exposed to carcinogens and a greater area for them to accumulate.Dogs affected with nasal cancer normally don't survive for more than one year.
“Short and medium-nosed dogs are more susceptible to lung cancer,because their shorter nasal passage aren't as effective at accumulating the inhaled secondhand smoke carcinogens,” MacAllister said.“This results in more carcinogens (致癌物质) reaching the lungs.”
Birds are also at risk for lung cancer,as well as pneumonia,because their respiratory systems are hypersensitive to any type of air pollutant.
To help prevent animals from being adversely affected by smoking,pet owners who smoke should have a designated smoking area that is separated from the home or stop smoking altogether,MacAllister said.
