The need to feed a growing population is putting much pressure on the world's supply of water. With 97% of the world's water too salty to be drunk or used in agriculture, the worldwide supply of water needs careful management, especially in agriculture. Although the idea of a water shortage(短缺)seems strange to someone fortunate enough to live in a high rainfall country, many of the world's agricultural industries experience constant water shortages.
Although dams can be built to store water for agricultural use in dry areas and dry seasons, the costs of water redistribution(重新分配)are very high. Not only is there the cost of the engineering itself, but there is also an environmental cost to be considered. Where valleys(山谷)are flooded to create dams, houses are lost and wildlife homes destroyed. Besides, water may flow easily through pipes to fields, but it cannot be transported from one side of the world to the other. Each country must therefore rely on the management of its own water to supply its farming requirements.
This is particularly troubling for countries with agricultural industries in areas dependent on irrigation (灌溉). In Texas, farmers' overuse of irrigation water has resulted in a 25% reduction of the water stores. In the Central Valley area of southwestern USA, a huge water engineering project provided water for farming in dry valleys, but much of the water use has been poorly managed.
Saudi Arabia's attempts to grow wheat in desert areas have seen the pumping of huge quantities of irrigation water from underground reserves. Because there is no rainfall in these areas, such reserves can only decrease, and it is believed that fifty years of pumping will see them run dry.

高三英语阅读理解困难题查看答案及解析
As the world’s population grows, farmers will need to produce more and more food. And large farms are increasingly using precision farming to increase yields (产量), reduce waste, and reduce the economic and security risks that inevitably accompany agricultural uncertainty.
Traditional farming relies on managing entire fields—making decisions related to planting, harvesting, irrigating, and applying pesticides and fertilizer (农药和化肥)—based on regional conditions and historical data. Precision farming, by contrast, combines sensors, robots, GPS, mapping tools and data-analytics software to customize(量身定制)the care that plants receive without increasing labor. Robot-mounted sensors and camera-equipped drones (无人机) wirelessly send images and data on individual plants to a computer, which looks for signs of health and stress. Farmers receive the feedback in real time and then deliver water, pesticide or fertilizer in adjusted doses(剂量)to only the areas that need it. The technology can also help farmers decide when to plant and harvest crops.
As a result, precision farming can improve time management, reduce water and chemical use, and produce healthier crops and higher yields—all of which benefit farmers’ bottom lines and conserve resources while reducing chemical runoff.
Many small businesses are developing new software, sensors, and other tools for precision farming, as are large companies such as Monsanto, John Deere, Bayer, Dow and DuPont. The U.S. Department of Agriculture, NASA and the National Oceanic and Atmospheric Administration all support precision farming, and many colleges now offer course work on the topic.
In a related development, seed producers are applying technology to improve plant characteristics. By following individual plants over time and analyzing which ones flourish in different conditions, companies can relate the plants’ response to their environments with their genomics (基因组学). That information, in turn, allows the companies to produce seed varieties that will grow well in specific soil and weather conditions. This advanced technology may also help to improve crop nutrition.
Farmers do not universally welcome precision agriculture for various reasons, such as high equipment costs and lack of access to the Internet. The technology may bring great challenges to experienced farmers who are not good at computers. And large systems will also be beyond the reach of many small farming operations in developing nations. But less expensive, simpler systems could potentially be applied. For others, though, cost savings in the long run may reduce the financial concerns. And however reticent some farmers may be to adopt new technology, the next generation of farmers are likely to warm to the approach.
1.Precision farming differs from traditional farming partly because it ________.
A. guarantees high yields with more labor
B. relies on regional conditions and historical data
C. offers plenty of water, pesticides and fertilizer
D. provides real time information about target crops
2.About precision farming, we can learn that________.
A. the government holds a cautious attitude
B. it draws positive responses from businesses
C. seed producers have already made huge profits
D. large systems will soon be built in developing nations
3.The underlined word “reticent” in the last paragraph probably means ________.
A. disappointed B. confused
C. unwilling D. shocked
4.What is the best title for the passage?
A. Precision Farming Increases Crop Yields
B. More Challenges Faced by Modern Farmers
C. Development of Farming Systems in the U.S.
D. Traditional Farming is Gradually Disappearing
高三英语阅读理解困难题查看答案及解析
The world has a fast growing population and people need more land for houses, factories, highways, and so on. The farmland is decreasing with each passing day. How to meet the need of feeding the growing population? One way is to introduce some high-output gene into a crop to enable it to produce more. Biologists over the years have discovered genes which can raise output of the crops, resist pests, improve taste, etc.
However, in many western countries there is widespread concern over the safety of“Genetically Modified”(GM) (转基因) foods, because they think there may be serious problems of environment, health, safety, morality and so on.
As a scientist I must admit GM foods involve great risks to humans. In fact in Europe they’re called “Frankenstein foods” by many. Frankenstein is a character in a novel. He was a very clever scientist. He created a monster(怪物), which eventually killed him.
Soybeans can be made into many foods. However, it’s hard to trace them. Therefore, it’s very important we have to make sure the soybean, if genetically modified, is free from any poisonous matter harmful to human beings. For this we need very good testing. We do have some testing on some animals, but no completely satisfactory testing has ever been made so far. They’re entirely new, and their problems are entirely unknown. It takes time to develop persuasive tests to know whether they’re harmful to us or not.
We may not be able to tell what may happen if we take GM foods. Some of them may be resistant to antibiotics (抗生素). Then many of the medicines we have today will have no effect on people eating GM foods.
A more likely case is the GM foods may contain genes some people are allergic to.
GM products have already come into our lives but most people even know nothing about it.
At least we have to be clear about what we are eating. The China Consumers Association is calling for labeling (标注) on GM foods so that consumers will know before they buy them.
1.The chief purpose of developing GM foods is to_______.
A. feed the fast growing population
B. make the foods much cheaper
C. make the foods much tastier
D. kill pests on the crops
2.From the passage we can infer that _____.
A. many Europeans reject GM foods
B. GM foods are very popular in Europe
C. Frankenstein foods can make people clever
D. Frankenstein was a scientist creating GM foods
3.The underlined phrase “trace them” in Paragraph 4 probably means“ ”.
A. find their market B. raise their quality
C. find their origins D. enjoy their taste
4.Which of the following is TRUE about GM foods?
A. The testing shows GM soybean foods are free from poisonous matter.
B. Sometimes consumers can hardly tell GM soybeans from natural ones.
C. GM foods prove to be safe to humans after some testing on animals.
D. GM foods problems have been known after testing on animals.
5.What can we learn from the passage?
A. GM foods make antibiotics fail to function properly.
B. People eating GM foods will suffer from food allergies.
C. As GM foods are safe at present, they’re certainly safe later on.
D. People should be informed of which foods are GM foods.

高三英语阅读理解中等难度题查看答案及解析
There is much more to growing up in a bilingual(双语的) family than learning two languages, and the cultural influences from both cultures are just as important.
In July we had a curious incident that shows the slight differences between cultures. My son has already changed a few of his baby teeth and since we lived in Italy we decided to go with the Italian version(版本) of the Tooth Fairy, which is not a fairy(仙女) but a little mouse. So last year when he lost his first tooth we had a visit from the little mouse who took the tooth away and left a rather good amount of coins --- when he lost the second tooth a few days later, however, the amount was significantly less! That in itself caused quite a few questions, but the real questions started when in July during a visit to the UK another tooth left my son’s mouth in Tooth Fairy land! The grandparents made a real problem out of it --- it was their first grandson’s tooth they got to say Goodbye to, so it was Tooth Fairy and rather generous, too!
The Qs & As
Son: Mum, how is the little mouse going to smell my tooth all this way? (as the story goes the little mouse smells a milk tooth and comes to collect it)
Me: No dear, it won’t! We are in England now so the Tooth Fairy will come.
Son: Oh, is she stronger than the little mouse? (I knew where this was going)
Me: She is very strong, and she is magic.
Son: What does the Tooth Fairy bring? (straight to the point)
Me: I am not sure. We’ll find out maybe a nice message.
Son: So is the little mouse coming too?
Me: No, it won’t make it all the way from Italy.
Son: But why don’t they have little mice in England?
Me: Because here the Tooth Fairy collects all baby teeth and she’s too fast, so the little mouse would always get there late.
Son: Oh!?
1.Italian kids are supposed to believe ________ will come and collect the milk teeth.
A. a little mouse
B. Tooth Fairy
C. their parents
D. the grandparents
2.The author thought Tooth Fairy would be rather generous because ________.
A. Italian parents often give much money for their kids’ lost baby teeth[
B. she knew Tooth Fairy was more generous than the little mouse
C. she knew the grandparents would give her son a big gift
D. English people are usually more generous than Italians
3.Hearing “Oh, is she stronger than the little mouse?”, the author knew her son was actually worried about ________.
A. the tooth fairy’s health
B. the little mouse’s coming
C. the amount of coins he could get
D. the story his grandparents know
4.By telling this story, the author intends to say it’s important to _________ in a bilingual family.
A. make kids know the folk stories
B. help kids choose one of the cultures
C. teach kids two languages
D. keep the balance of both cultures

The beet (甜菜) is a tasty root vegetable that does not require much work to grow. People think of beets as being always dark red,but they can also be pink,yellow or white. Beets are high in nutrients,and both the root and the tops can be eaten. The leaves make good salads when the plants are young,and the greens can be cooked when the plants are older. Beets grow best in full sun and in loose soil that is not too wet.
Remove stones from the soil while preparing the ground,and test it before adding fertilizer Beet seeds can be planted as soon as the soil can be worked at the start of the growing season. Planting them every two or three weeks will provide a continuous harvest into the fall. A beet seed is a fruit containing several seeds. Overcrowding the plants will mean that the roots cannot spread out and grow,so thin the beets by removing the smaller ones and using them as greens.
A specialist named Cindy Haynes says little or no fertilizer is needed in rich soils. Once the seeds are planted,however,she suggests covering the soil to protect it from the rain and during dry periods. She also suggests putting a fence around the plants to keep away rabbits and deer. She says the only work beets need once they have been thinned is weeding and, when the weather is dry,a weekly watering. For best results,beets should be picked when the roots are two and one-half centimeters around. Larger beets can be tough,and have to be cooked for a long time. Beets can be eaten in many ways.
60.What is the second paragraph mainly about?
A. How to test the soil. B. How to plant beets
C. When to harvest beets. D. When to plant beets.
61.Smaller beets are often removed in order to________.
A. give other beets space to grow B. add more fertilizer to the soil
C. plant new seeds D. use the green,young leaves in salads
62.What may the next part of the last paragraph be about?
A. When to pick beets. B. How to eat beets.
C. The uses of beets. D. The taste of larger beets.
63.The passage is most probably from a(n)________.
A. gardening book B. education magazine C. science report D. entertainment magazine
