Ⅵ.阅读理解
Let us consider what we can do for the food problem.
The simple way to increase food production，one might suppose，is to bring more land into farmland and put more people to work on it.
But it is proved in some developing countries that this will bring some problems.It will quickly make the soil poorer and destroy forest growth.Furthermore，the people there will always find they need more people to work on this land to produce more food.
During the past twenty years，some developing countries have increased a lot more farmland in their countries，but their populations have in the meantime grown faster，therefore，they are further behind than before.And their food increase has been gained at the cost of using up the rich lands.Many of the lands have become poor lands and are producing less food now.
Meanwhile，farming in the developed countries has produced much more food through improved technology.Since 1940，farmland has been reduced by 7 percent in the United States but cereal production has jumped by 60 percent.The increase in the corn output，thanks to hybrid corn，has been even greater.
The “secret”is to apply fertilizer，in scientific ways，of course.And compared to the developing countries，the populations in developed countries have increased just a little larger than twenty years ago.
On the whole，world population today is increasing at the speed higher than ever before.Every year the population is two percent larger，so that the 6,000,000,000 people on the earth today will present another 120,000,000 mouths to be fed by the time next year.It is a fearsome thought that this time tomorrow there will be about 330,000 persons added to this world population.
What can we do about the increase of population，or the lack of food to feed such a large，growing population？That's a very important problem before everyone on the earth，young or old，men or women.
1．In the author's opinion，________ seems to be the most serious problem today.
A．pollution
B．lack of food
C．poor farmland
D．the increase of world population
答案 B [细节理解题。本文主要讲述了如何解决世界上的粮食短缺问题，故选B。]
2．From the agriculture history in the US，we can conclude that ________.
A．the more population there is，the less food there is
B．the richer a country is, the richer it will become
- 6 -
C．science will be helpful in feeding the world population
D．developing countries cannot settle their food problem
答案 C [推理判断题。根据第五段可知，美国的耕地减少了百分之七，但是通过高科技，谷物产量却增加了百分之六十。]
3．The author seems to suggest that the food problem cannot be settled unless ______.
A．we stop getting more land into farmland
B．everyone realizes how serious the problem is
C．pollution is stopped
D．there is no more room for no more people
答案 B [推理判断题。根据最后一段中的“That's a very important problem before everyone on the earth，young or old，men or women.”可知，粮食短缺问题是世界上每一个人所面临的大问题。大家都应行动起来，共同应对这一难题。]
4．The best title for this passage should be “________”．
A．More people feed on less food
B．The population problem
C．How to deal with the food problem
D．Science and technology in food production
答案 C [主旨大意题。本文主要讲述了世界上的粮食短缺问题以及解决这一问题的途径。A项只提出了粮食短缺问题。B项离话题太远。D项只说明了科技在粮食问题上的作用。这三项都不全面。]
