The Population of My Hometown
三、任务型阅读。
The population problem may be the greatest one of the world today. The world's population is growing faster and faster. Two thousand years ago, there were only 250 million people on the earth. Four hundred years ago, the number was over 500 million. But at the beginning of the 20th century, the world's population was about 1,700 million. In 1970, the number was 3 ,600 million. In 1990, the number was five billion. A UN report said that the world population had passed six billion by the end of the 20th century. This was just ten years after it reached five billion. By October 31 , 2011 , with a new baby's birth , the world's population has reached 7 billion. But another billion is coming by 2025 , and the total will reach 10 billion before the end of the century.
