World Population(世界人口)
World PopulationAccording to a recent report from the United Nations, the world population continues to grow. It is over 5 billion now. It could reach 8.4 billion in the year 2025.
But during the past 10 years or so, a large and rapid drop in the world's birth rate has taken place.Families generally are smaller now than they were a few years ago. It is happening in both developing and developed countries.
China is such a country that has already cut its rate of population growth by about one half since ! 970. Each Chinese family has no more than one child. And the hope is to reach a zero population growth rate by 2010.
Several countries in Europe already have a negative growth rate. Experts say that these countries 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 retirees.
世界人口
根據(jù)聯(lián)合國最近的報告：世界人口正持續(xù)增長。 現(xiàn)已超過50億。到2025年，這個數(shù)字會達到84之多，
但是在過去的大約10年中，世界范圍的出生率有了大量、迅速的下降。與幾年前相比，家庭成員越來越少，，發(fā)達國家和發(fā)展中國家都是如此。
中國正是一個這樣的國家，197()年至今。人口的增長率已經(jīng)大約減少為過去的二分之一。每個中國家庭只有一個孩子。到2010年的時候，有希望達到人口增長率為零
很多歐洲國家已經(jīng)出現(xiàn)人口負增長。 專家預測，這些國家將會在未來遭遇嚴重的勞動力不足。 而工作的人們將面臨比現(xiàn)在高得多的稅收以負擔日益增長的退休人口。
