答案

The Problem of Human Population
It has been estimated that a thousand years ago there were less than 400 million people on earth.  Today, however, the world’s population has amounted to 5,000 million.  What is worse, it keeps growing at a surprising speed.  If this trend continues, the world’s population will shoot up to 7,000 million by the year 2000.  This is what we call population explosion.The rapid development of science and technology is the main cause of population explosion.  We can see that the population has been growing at a tremendous speed since the Industrial and Agriculture Revolution in 1650, which raised the people’s standard of living, and the emergence of modern medicine in 1550, which lowered the people’s death rate.Population explosion will result in a lot of such problems as food shortage, housing shortage and unemployment.  It is time that we acted quickly to carry out the policy of birth control otherwise, man’s survival on the earth will be threatened.

解析

试题分析：这是一篇给材料作文，要求写一篇介绍中国人口问题的短文。题目中给出的材料较为详细，动笔前应根据材料内容组织语言，列出简单提纲，确定句子的时态，关键单词等问题。注意不要遗漏要点，问候可以适当表达自己的观点。通过阅读材料可知这篇短文时态问题比较复杂，注意时态与时间状语的搭配问题。写作中注意语义通顺，符合逻辑关系。上下文之间可以适当使用连接词。
