Urbanization

Until relatively recently, the vast majority of human beings lived and died without ever seeing a city. The first city was probably founded no more than 5,500 years ago. 1. In fact, nearly everyone lived on farms or in tiny rural villages. It was not until the 20th century that Great Britain became the first urban society in history—a society in which the majority of people live in cities and do not farm for a living.

Britain was only the beginning. 2. The process of urbanization—the migration of people from the countryside to the city—was the result of modernization, which has rapidly transformed how people live and where they live.

In 1990, fewer than 40% of Americans lived in urban areas. Today, over 82% of Americans live in cities.

Only about 2% live on farms. 3.

Large cities were impossible until agriculture became industrialized. Even in advanced agricultural societies, it took about ninety-five people on farms to feed five people in cities. 4. Until modern times, those living in cities were mainly the ruling elite(精英) and the servants, laborers and professionals who served them. Cities survived by taxing farmers and were limited in size by the amount of surplus food that the rural population produced and by the ability to move this surplus from farm to city.

Over the past two centuries, the Industrial Revolution has broken this balance between the city and the country. 5. Today, instead of needing ninety-five farmers to feed five city people, one American farmer is able to feed more than a hundred non-farmers.

A. That kept cities very small.

B. The rest live in small towns.

C. The effects of urban living on people should be considered.

D. Soon many other industrial nations become urban societies.

E. But even 200 years ago, only a few people could live in cities.

F. Modernization drew people to the cities and made farmers more productive.

G. Modern cities have destroyed social relations and the health of human beings.

It’s been a difficult year. My daughter, my dog and I lost our home. We’ve depended upon the kindness of others to provide temporary shelter.

1. At one point, I felt as though my daughter might be better off without me. If she were placed with a rich family, she would have a good life. I was unable to provide a good life for her. However, she never complains, although she has every right to. She went from having a beautifully decorated bedroom of her own, to having temporary shelter. 2.

I dug through the change at the bottom of my purse and bought her a lollipop at the store today. She’d had her eye on it the entire time we were in line to pay for our purchase. It was an old-fashioned one that cost $1.00.3. It was the end of the month and I only had $1.35 left to my name. However, she’d been such a good girl, and I really thought she deserved a special treat.

I reached into my purse and counted out enough for the lollipop. You would have thought I gave her the key to the magic kingdom! “Thank you, Mommy! You’re the best mommy!”4.

All at once, the cloud of despair that had hung over me lifted.5. I was ready to continue my journey, willing to face whatever challenges may lie ahead.

A.I really couldn’t afford it.

B.I became upset at my loss.

C.I could see tears shining in her eyes.

D.I wouldn’t have any money coming until the first of next month.

E.She screamed with joy as she hugged me with all her strength.

F.I knew without a doubt in that very instant that I was the family that my little girl needed.

G.She doesn’t complain that I can’t afford to give her the extra things she would love to have.

For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive (善于接受的) to such messages.

Scientists are using powerful radio telescope to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan (扫视) the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.

Of the 200 billion stars in the Milky Way galaxy (银河星系), scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.

However, many scientists wonder whether intelligent (有智力的) life exists on other planets. Some believe that twenty years of searching without any intelligible (可理解的) messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.

Other scientists believe that our search hasn’t been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family in only about five billion years old, our galaxy is about 20 billions years old. In that time, some scientists think it is likely that civilizations are much more advanced than ours. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.
