Answer 1

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.

試題分析：這是一篇給材料作文，要求寫一篇介紹中國人口問題的短文。題目中給出的材料較為詳細，動筆前應根據(jù)材料內容組織語言，列出簡單提綱，確定句子的時態(tài)，關鍵單詞等問題。注意不要遺漏要點，問候可以適當表達自己的觀點。通過閱讀材料可知這篇短文時態(tài)問題比較復雜，注意時態(tài)與時間狀語的搭配問題。寫作中注意語義通順，符合邏輯關系。上下文之間可以適當使用連接詞。
【亮點說明】這篇短文使用了大量的固定句式和短語，為文章增色不少. 如: It has been estimated that據(jù)估計……； What is worse,更糟的是；shoot up to飆升到；result in導致，結果是；It is time that該做某事了。學習中注意總結,牢記一些固定句式及短語,寫作時就可以適當引用,使文章的表達更有邏輯性,更富有條理.
