128. A sharp Increase in World Population 世界人口的激增

According to the figures given in the bar charts, it took the beginning of human life to the year 1830 for the population of the earth to reach one billion.

根據(jù)上述柱狀圖，我們可以看出，世界人口的第一個十億是從生命之初直到1830年。

That process took at least two million years. After that, the world population increased rapidly, adding up to two billion in 1930, while in 1960 the next billion was formed, only within 30 years. From then on the global population was on a crazy rise, amounting to 4 billion in 1975, with only 15 years afterwards.

該過程歷時兩百萬年。此后，世界人口迅速增長，1930年達(dá)到20億，而1960年則達(dá)到30億，期間只用了30年。此后的人口增速更加瘋狂。1975即達(dá)到40億，只用了15年。

Two reasons might be considered to account for these great changes in the world population. To begin with, with the development of science and technology in the field of medicine, the birth rate is continuously climbing. To make things worse, some countries, especially the developing countries, seldom take any birth control policy. On the other hand, the death rate is steadily declining because of the improved living standards.

世界人口增長速度的變化歸因于兩點：首先，隨著醫(yī)藥領(lǐng)域里的科技發(fā)展，人口出生率一直在攀升。更糟的是，有些國家，尤其是發(fā)展中國家，很少采取計劃生育政策。另一方面，隨著生活水平的提高，死亡率則呈下降趨勢。

In the future, we must take effective measures to control world population growth . Otherwise, the world would not be able to put up with the exploding population.

將來，我們應(yīng)該把人口增長限定在一定范圍內(nèi)，否則，地球?qū)o法承受爆炸的人口。
