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 Americans’ need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and spring 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.In the 18th and early 19th centuries, passenger pigeons________.

Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn’t know at that time that 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 Earth Day.
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.According to Anderson, before 1970, Americans had little idea about ________.

Arriving in Sydney on his own from India, my husband, Rashid, stayed in a hotel for a short time while looking for a short time while looking for a house for me and our children.
During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.
He reported the case to the police and then sat there, lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.
Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can（垃圾桶）that had been left out on the footpath.
My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.
