There now are about 4 billion of us on earth. That could reach 6 billion by the end of the century and 11 billion in a further 75 years. Experts have long been concerned about such a growth. Where will we find the food, water, jobs, houses, school and health care for all these people?A major new study shows that the situation may be changing.A large and rapid drop in the world’s birth rate has taken place during the past 10 years. Families generally are smaller now than they were a few years ago. It is happening in both developing and industrial nations.Researchers said they found a number of reasons for this. More men and women are waiting longer to get married and are using birth control devices and methods to prevent or delay pregnancy. More women are going to school or working at jobs away from home instead of having children. And more governments, especially in developing nations, now support family planning programs to reduce population grow.China is one of the nations that have made great progress in reducing its population growth. China has already cut its rate of population growth by about half since 1970.Each Chinese family is now urged to have no more than one child. And the hope is to reach a zero population growth with the total number of births equaling the total number of deaths by the year 2000.Several nations in Europe already have fewer births than deaths. Experts said that these nations could face a serious shortage of workers in the future. And the persons who are working could face much higher taxes to help support the growing number of retired people.1.

My friend was waiting for me when my plane landed at Kennedy Airport at three o’clock in the afternoon. The weather was very cold and it was snowing, but I was too excited to mind. From the airport, my friend and I took a taxi to my hotel. On the way, I saw the skyline of Manhattan for the first time and I stared in astonishment at the famous skyscrapers and their man-made beauty. My friend helped me unpack at the hotel and them left me because he had to go back to work. He promised to return the next day.Shortly after my friend had left, I went to a restaurant near the hotel to get something to eat. Because I couldn’t speak a word of English, I couldn’t tell the waiter what I wanted. I was very upset and started to make some gestures, but the waiter didn’t understand me. Finally, I ordered the same thing the man at the next table was eating. After dinner, I started to walk along Broadway until I came to Times Square with its movie theatres, neon lights, and huge crowds of people.I did not feel tired, so I continued to walk around the city.I wanted to see everything on my first day. I knew it was impossible, but I wanted to try.When I returned to the hotel, I was exhausted, but I couldn’t sleep because I kept hearing the fire and police sirens during the night.
