1 . Passenger pigeons (旅鸽) once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群) so large that they darkened the sky for hours.

It was calculated that when its population reached its highest point, there were more than 3 billion passenger pigeons—a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.

Sadly the abundance of passenger pigeons may have been their undoing. Where the birds were most abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.

By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by American’s need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and storms contributed to their decline. Soon the great flocks were gone, never to be seen again.

In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1, 1914.

2 . Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many， many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

Twenty –five years ago, there were hardly any education programs for environment. Today, it’s hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” says Bruce Anderson.

1. According to Anderson, before 1970, Americans had little idea about ___.

A．the social movement	B．recycling techniques

C．They have lowered their CO levels in forty cities.

D．They have reduced pollution through effective measures.

C．Green living	D．CO reduction

3 . 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
There are thousands of coral reefs (珊瑚礁) in the world; Unfortunately, however, they are now in serious danger. More than one-third are in such bad shape that they could die within ten years.    1    Here are the three main causes discovered.
The first cause is pollution on land. The pollutants run with rainwater into rivers and streams, which carry the poisons into the ocean.    2    So they will be easily infected (感染) with diseases.
    3    Higher ocean temperatures kill the important food source (来源) for the coral—the algae, the tiny greenish-gold water plants that live on coral.    4    This process has happened more and more frequently in recent years.
The last factor contributing to the disappearance of coral reefs is people. People sometimes crash into reefs with their boats, breaking off large blocks of coral.    5    Moreover, some people even break coral off to collect for souvenirs since it is so colorful and pretty.

A．Global warming is another reason.

B．Many might not even last that long!

C．Divers who walk on reefs can also do serious damage.

D．Reefs provide a home for 25% of the fish in the ocean.

E．Chemicals from the poisons kill reefs or make them weak.

F．Steps must be taken now to stop over-fishing and pollution of the oceans.

G．When the algae die, the coral loses its color and it also dies in the end.

4 . Going green seems to be fad (时尚) for a lot of people these days. Whether that is good or bad, we can’t really say, but for the two of us, going green is not a fad but a lifestyle.

On April 22,2011,we decided to be green every single day for an entire year. This meant doing 365 different things, and it also meant challenging ourselves to go green beyond the easy things. Rather than recycle and reduce our energy, we had to think of 365 different things to do and this was no easy task.

With the idea of going green every single day a year, Our Green Year started. My wife and I decided to educate people about how they could go green in their lives and hoped we could show people all green things that could be done to help the environment. We wanted to push the message that every little bit helps.

Over the course of Our Green Year, we completely changed our lifestyles. We now shop at organic (有机的) stores. We consume less meat, choosing green food. We have greatly reduced our buying we don’t need. We have given away half of what we owned through websites. Our home is kept clean by vinegar and lemon juice, with no chemical cleaners. We make our own butter, enjoying the smell of home-made fresh bread. In our home office anyone caught doing something ungreen might be punished.

Our minds have been changed by Our Green Year. We are grateful for the chance to have been able to go green and educate others. We believe that we do have the power to change things and help our planets.

5 . Sam, a dog, was left behind in Colorado while his owners, Mr. And Mrs. Green moved to Southern California. They did not give the dog up. They found him a very nice home before they moved. They would have let Sam accompany them, but they were afraid the dog’s presence would make it difficult for them to rent a house when they reached their destination.
The Green family lived in Colorado for less than a year. Before that, they had lived in the same neighborhood in California to which they returned. So Sam had been there before, but only for a short time when he was young.
Several months after the Greens left Colorado, after they were comfortably settled back in California, they heard a scratch at the door. They couldn’t imagine who might be there. It never occurred to them that it might be Sam, because they were sure he was happily set up with his new family back in Colorado. When they opened the door, the Greens saw a dirty, tired dog with very hurting feet. The animal looked a little bit like Sam, but no one could believe that Sam could have walked 840 miles on his own. The tired dog spent the night under the family car. The next day, when he was more rested, he performed some of his old tricks. The Greens knew they had their own dog back.

7 . Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately：the air you breathe.

Previous studies have linked high exposure (暴露) to environmental pollution to an increased risk of heart problems，but two analyses now show that poor air quality can lead to heart attack or stroke (中风) within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物) were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA)considers to be of “moderate” (良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

1. The text mainly discusses the relationship between ________.

A．heart problems and air quality

B．heart problems and exercising

C．heart problems and smoking

D．heart problems and fatty food

2. The underlined word “modest” in Paragraph 3 most probably means ________.

A．relatively high	B．extremely low
C．relatively low	D．extremely high

3. What can we learn from the text?

A．Eating fatty food has immediate effects on your heart.

B．The EPA conducted many studies on air quality.

C．Moderate air quality is more harmful than smoking.

D．Stricter regulations on pollutants should be made.

4. The author's purpose of writing the text is most likely to ________.

A．inform	B．persuade
C．describe	D．entertain

8 . There are 132 rooms, 32 bathrooms, and 6 floors to accommodate all the people who live in, work in, and visit the White House. There are also 412 doors, 147 windows, 28 fireplaces, 7 staircases, and 3 lifts.
At various times in history, the White House has been known as the “President’s Palace”, the “President’s House”, and the “Executive Mansion”. President Theodore Roosevelt officially gave the White House its current name in 1901.
The White House receives approximately 6,000 visitors a day.
With five full-time chefs, the White House kitchen is able to serve as many as 140 guests and hors d’oeuvres (开胃菜) to more than 1,000 people.

9 . One moment it was quiet and calm in the forest, the next, the air was charged with tension. The elephant had heard the distant alarm calls of animals and her mood suddenly changed. I urged the elephant deeper into the forest. We sounded like a forest fire-crackling, snapping, trailblazing. But through all the noise came a sharp warning cry. The elephant stopped and we heard it again — the tell-tale call of a spotted deer.

I looked quickly around the shadows of the forest. Rays of sunlight shone through tree branches, beneath which the patchwork (交错) of green plants and shadows-within-shadows would make tiger stripes (条纹) look more attractive. Apart from an occasional noise from the elephant’s stomach, the forest was silent.

Gradually, the tension slipped from our bodies. The elephant seized a nearby branch and put it into her mouth. I reached forward and gently moved my hand over the elephant’s neck; there was a soft part, free of wrinkles and hairs, behind her ear.

This was my fourth time to sense the aura of the forest in Corbett, although I saw no tigers in the end. Located at the foot of the Himalayan mountains, Corbett is home to about 135 Bengal tigers, but the forest seemed to be guarding their whereabouts(出没处), a silent reminder of their secrecy and rarity. Still, I was happy enough touching the elephant behind the ear. If I had so desperately wanted to see a tiger, I could have gone to a zoo. After all, spotting tigers merely confirms their beauty; tracking them can make you aware of something more.

When I was a child, I hoped to live in the city. I think I would be happy there. Now I am living in a city , but I miss my home in countryside. There the air is clean or the mountains are green. Unfortunately, on the development of industrialization, the environment has been polluted. Lots of studies have been shown that global warming has already become a very seriously problem. The airs we breathe in is getting dirtier and dirtier. Much rare animals are dying out . We must found ways to protect your environment. If we fail to do so , we‘ll live to regret it .
