【解析】文章讲述的是人口迅速增长带来的一系列问题，号召我们一定要尽快采取行动。

1.study 意为“研究”，根据下文，这是指对未来20年地球上的情况变化所作的研究。

2.与后面的人口增长，环境污染等联系起来看，在2010年地球上的状况(picture)将会令人不愉快(unpleasant)。

3.因为人口继续增长，所以世界会越来越拥挤(crowded)。

4.指人口数目的多用large，不用small。指人口达到某一数目用“as large as + 数词”。

5.从现状来看，人口增长快的国家多为发展但不发达的国家；而城市人口急剧增长的则是一些发展中的国家(developing countries)。

6.前面提到了两个城市，故此空只能填each。neither具有否定意义，不合句意，不能插入谓语之中。

7.相临几句是讲粮食增长问题，故选increase“增长”。

8.前后两句具有转折意义：农民所生产的粮食将比1985多90%，但多数增产粮食的国家是已经有足够粮食供人们生活的国家。

9.already 意为“已经”，由下句可知：是指已经有足够粮食供人们生活的国家。

10.expect意为“预计”，句意为：在亚洲南部的国家预计增产幅度不大。

11.由changing farms into deserts可知：不当农业生产方式毁坏(destroy)了大片生产粮食的土地。

12.由于扩建城市，修建房屋，必然侵占大量农田，故选lost(失去)。

13.由burn coal and oil必然排放大量烟雾，可推知：此处指空气污染(air pollution)

14.由more and more trees are cut down可推知：此处指森林(forests)可能消失。

15.此句意为：专家说地球到2010年的状况可能会不好。

16.exist 意为“存在”。由上下文可知：环境正遭受污染和破坏，专家们只是想保存今天的状况。

17.settle the problems 意为“解决问题”。

18.still 意为“还有”，加强语气。句意为：现在还有时间给世界各国制定行动计划。

19.work out a plan 意为“制定计划”。

20.句意为：专家们警告说等待太长的时间作出决定将会极大地减少成功的机会来源：
