Farming is moving indoors, where the sun never shines, where rainfall is irrelevant (無關(guān)的) and where the climate is always right. The perfect crop field could be inside a windowless building with controlled light, temperature，humidity，air quality and nutrition. It could be in a New York high- rise or a complex （建筑群） in the Saudi desert. It may be an answer to the world’s food problems.
The world already is having trouble feeding itself. Half the people on Earth live in cities, and nearly half of those – about 3 billion – are hungry or ill–fed. Food prices, currently increasing, are badly affected by dryness, floods and the cost of energy required to plant, harvest and transport it. And prices will only get more unstable. Climate change makes long-term crop planning uncertain. Farmers in many parts of the world already are using water available to the last drop. And the world is getting more crowded: by mid-century, the global population will grow from 6.8 billion to 9 billion.
To feed so many people may require expanding farmland at the expense of forests and wilderness, or finding ways to greatly increase crop output.
Gertjan Meeuws and three other Dutch bioengineers grow vegetables and house plants in closed and regulated environments. In their research station, water flows into the pans when needed, and the temperature is kept constant. Lights go on and off, creating “day” and “night”, but according to the rhythm of the plant.
Meeuws says a building of 100 square meters and layers of plants could provide a daily diet of 200 grams of fresh fruit and vegetables for the entire population of Ken Bosch, about 140,000 people. Their idea isn’t to grow foods that require much space, like corn or potatoes.
Sunlight is not only unnecessary but can be harmful. Plants need only specific wavelengths of light to grow. Their growth rate is three times faster than under greenhouse conditions. They use about 90 percent less water than outdoor agriculture. And city farming means producing food near the consumer, so there’s on need to transport it long distances.
【小題1】According to the text, Gertjan Meeuws’ farming _______.

A．can be used for corn production
B．is much like greenhouse farming
C．is adaptable to any environment
D．uses more water than outdoor farming
【小題2】What is the second paragraph mainly about ?

America is growing older. Fifty - eight years ago, only 4 out of every 100 people in the United States were 65 or older. To day, 10 out of every 100 Americans are over 65. The aging of the population will affect（影響）American society in many ways—education, medicine, and business. Quietly, the graying of America has made us a very different society—one in which people have a quite different idea of what kind of behavior（行為） is suitable（合適）at various , ages.
　　A person s age no longer tells you anything about his/her social position, marriage or health. There’s no longer a particular year in which one goes to school or goes to work or gets married or starts a family. The social clock that kept us on time and told us when to go to school, get a job, or stop working isn’t as strong as it used to be. It doesn’t surprise us to hear of a 29 - year - old university president or a 35 - year -old grandmother, or a 70 year - old man who has become a father for the first time. Public ideas are changing.
　　Many people say, “I am much younger than my mother— or my father— was at my age. ”No one says“Act your age” any more. We’ve stopped looking with surprise at older people who act in youthful ways.
【小題1】It can be learnt from the text that the aging of the population in America ________ .

A．has made people feel younger
B．has changed people’s social position
C．has changed people’s understanding of age
D．has slowed down the country’s social development
【小題2】The underlined word “one” refers to ________ .
A．a(chǎn) societyB．America
C．a(chǎn) placeD．population
【小題3】“Act your age” means people should ________ .
A．be active when they are old
B．do the right thing at the right age
C．show respect for their parents young or old
D．take more physical exercise suitable to their age
【小題4】If a 25 - year - old man becomes general manager of a big firm, the writer of the text would most probably consider it ________ .
A．normalB．wonderful
C．unbelievableD．unreasonable

科目：高中英語 來源：2010年高考英語試題分類匯編——故事類閱讀理解 題型：閱讀理解


I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?” He looked perturbed (不安).“Do you want to try it first?" he said. It didn't quite sound like a question. "Do I need to?" I replied. "There's nothing wrong with it?" This made him look a bit insulted and I started to feel bad. "No, no. But you should try it," he said encouragingly." Compare it with the others. "
I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.
But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant seemed a sincere man. So I let him take out my chosen camera from the cupboard, show how it took excellent pictures of my fellow shoppers... and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well.
Why do we think that new options (選擇) still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.
1. The shop assistant insisted that the writer should __ .
A. try the camera to see if there was anything wrong with it
B. compare the camera he had chosen with the others
C. get more information about different companies
D. trust him and stop asking questions
2. What does the writer mean by "it would be worth half what I paid for it"  (Paragraph 2) ?
A. He should get a 50% discount.
B. The price of the camera was unreasonably high.
C. The quality of the camera was not good.
D. The camera would soon fall in value.
3. The writer decided to try the model he had chosen because he __ .
A. knew very little about it
B. didn't trust the shop assistant
C. wanted to make sure the one he chose would be the best
D. had a special interest in taking pictures of his fellow shoppers
4. It can be inferred from the passage that in the writer's opinion, __
A. people waste too much money on cameras
B. cameras have become an important part of our daily life
C. we don't actually need so many choices when buying a product
D. famous companies care more about profit than quality
