A
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 there and destroy forest growth. Further more, 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 farther 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 more food through improved technology. Since 1940, farmland has been reduced 7 percent in the United States but cereal (谷物) production has jumped 60 percent. The increase in the corn output, thanks to hybrid corn (杂交玉米), has been even greater.
The secret is 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 added to this world population some 360,000 persons.
What can we do about the increase of population，or the lack of food to feed such a large, increasing population? That is 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
答案与解析 D 由最终一段“What can we do about the increase of population ...”，及倒数其次段人口增长的几个数据可知。
2. To get enough food for the world population，________.
A. we should develop farming science and technology
B. we should get more land into farmland
C. developed countries should produce more food
D. developing countries should stop making forests into farmland
答案与解析 A 由第五段“Meanwhile，farming ... through improved technology.”可知。
3. From the agriculture history in 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
C. science will be helpful in feeding the world population
D. developing countries cannot settle their food problem
答案与解析 C 由倒数第四段“Since 1940 ... has been ... even greater.”及倒数第三段“The secret is scientific ways ...”可知。
4. 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 more people
答案与解析 B 文章最终一句“That is a very important problem before everyone on the earth ...”可知。
B
Polly Jones lived on a farm. She had lived there all her life，all twelve years of it. Her father, who managed the farm，had just lifted the potato crop. Prices were high; he wanted to sell the crop as quickly as he could.
Polly wandered over the rough field looking for the small potatoes that the pickers had accidentally missed. She found one，then another，then a handful. She was pleased. They were delicious once cooked. Then she caught sight of something else. It looked like a piece of colored stone. Polly picked it up and thought how pretty it was. She could see a pattern on it, a picture of a fish and a part of a leaf. She scraped the soil away around her feet and found that she was standing on what seemed to be a piece of pavement. Stuck to another piece of stone was something small and round like a button. She realized it was an old coin.
The field was busy the next morning though not with potato pickers. In front of the house where the farm machinery usually stood were several cars and a police van. A group of distinguishedlooking men and women had appeared the morning after her father's telephone call. The local television station had shown some pictures of the field with Polly pointing to the place where she had found her pavement. It was proved to be of Roman origin and was being described as the most exciting thing that had happened in the area since the end of the Second World War. In those days an American airbase had occupied the site of the potato field.
A week later about forty students arrived from the local university. That afternoon a truck with equipment arrived. The excavation (挖掘) was officially under way. Permission had been given and the “dig”， as it was called, was expected to last several months. Polly wondered how the everyday work of the farm would get done with so many strange people around and cars coming and going all day long. All the unusual activities had made the cows and sheep restless. Her father said their cows produced less milk.
Still, it was interesting and of great fun. They had let her keep the gold coin. From then on, Polly would always walk carefully over potato fields.
5. There were still potatoes in the field because the pickers ________.
A. had left them for Polly on purpose
B. thought they were too small
C. would pick them later
D. had failed to notice them
答案与解析 D 由其次段第一句“... looking for the small potatoes that the pickers had accidentally missed.”可知。
6. When Polly was looking for potatoes ________ caught her attention first.
A. a part of a leaf B. an old coin
C. a piece of pavement D. a button
答案与解析 C 由其次段“... and found that she was standing on what seemed to be a piece of pavement.”可知。
7. Why did the findings cause great excitement?
A. The coin was priceless.
B. An ancient Roman site was discovered.
C. Few old coins had been found since the War.
D. Such old coins had been found in American airbases.
答案与解析 B 由第三段“It was proved to be of Roman origin ...”可知。
8. How did the “dig” affect the life on the farm?
A. It brought the farmers wealth overnight.
B. It prevented Polly from attending class.
C. It attracted more farmers to the potato fields.
D. It reduced milk production.
答案与解析 D 由第四段最终一句“Her father said their cows produced less milk.”可知。双基限时练(五) Unit 2 Part Ⅱ

6．I remembered ________ (lock) the door before I left the office, but forgot to turn off the lights.
