解析:

1. D。study 意為“研究”，根據(jù)下文，這是指對未來20年地球上的情況變化所作的研究。

2. B。與后面的人口增長，環(huán)境污染等聯(lián)系起來看，在2010年地球上的狀況(picture)將會令人不愉快(unpleasant)。

3. C。因為人口繼續(xù)增長，所以世界會越來越擁擠(crowded)。

4. D。指人口數(shù)目的多用large，不用small。指人口達到某一數(shù)目用“as large as + 數(shù)詞”。

5. A。從現(xiàn)狀來看，人口增長快的國家多為發(fā)展但不發(fā)達的國家；而城市人口急劇增長的則是一些發(fā)展中的國家(developing countries)。

6. B。前面提到了兩個城市，故此空只能填each。neither具有否定意義，不合句意，不能插入謂語之中。

7. C。相臨幾句是講糧食增長問題，故選increase“增長”。

8. B。前后兩句具有轉(zhuǎn)折意義：農(nóng)民所生產(chǎn)的糧食將比1985多90%，但多數(shù)增產(chǎn)糧食的國家是已經(jīng)有足夠糧食供人們生活的國家。

9. A。already 意為“已經(jīng)”，由下句可知：是指已經(jīng)有足夠糧食供人們生活的國家。

10. D。expect意為“預(yù)計”，句意為：在亞洲南部的國家預(yù)計增產(chǎn)幅度不大。

11. A。由changing farms into deserts可知：不當農(nóng)業(yè)生產(chǎn)方式毀壞(destroy)了大片生產(chǎn)糧食的土地。

12. B。由于擴建城市，修建房屋，必然侵占大量農(nóng)田，故選lost(失去)。

13. A。由burn coal and oil必然排放大量煙霧，可推知：此處指空氣污染(air pollution)

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

15. D。此句意為：專家說地球到2010年的狀況可能會不好。

16. C。exist 意為“存在”。由上下文可知：環(huán)境正遭受污染和破壞，專家們只是想保存今天的狀況。

17. A。settle the problems 意為“解決問題”。

18. B。still 意為“還有”，加強語氣。句意為：現(xiàn)在還有時間給世界各國制定行動計劃。

19. C。work out a plan 意為“制定計劃”。

20. D。句意為：專家們警告說等待太長的時間作出決定將會極大地減少成功的機會。
