Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use. This is especially true in agriculture, where sustainable development is often taken as the measure of progress without a proper appreciation of historical and cultural perspectives.
To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so. Medieval agriculture in northern Europe fed, clothed and sheltered a mainly rural society with a much lower population density than it is today. It had minimal effect on biodiversity, and any pollution it caused was typically localized. In terms of energy use and the nutrients captured in the product it was relatively inefficient.
Contrast this with farming since the start of the industrial revolution. Competition from overseas led farmers to specialize and increase yields. Throughout this period food became cheaper, safer and more reliable. However, these changes have also led to habitat loss and to reducing biodiversity.
All this means that agriculture in the 21st century will have to be very different from how it was in the 20th. This will require thorough thinking. For example, we need to move away from the idea that traditional practices are certainly more sustainable than new ones. We also need to abandon the notion that agriculture can be “zero impact”. The key will be to abandon the rather simple and static(稳定的)measures of sustainability, which centre on the need to maintain production without increasing damage. Instead we need a more dynamic interpretation, one that looks at the pros and cons of all the various way land is used. There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity. It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting. But we do not know whether lower carbon footprints will always be better for biodiversity.
What is important is recognizing that sustainable agriculture is not just about sustainable food production.

Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use．This is especially true in agriculture, where sustainable development is often taken as the sole measure of progress without a proper appreciation of historical and cultural perspectives．
To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so ．Medieval agriculture in northern Europe fed, clothed and sheltered a predominantly rural society with a much lower population density than it is today．It had minimal effect on biodiversity, and any pollution it brought about was typically localized．In terms of energy use and the nutrients captured in the product it was relatively inefficient．
Contrast this with farming since the start of the industrial revolution．Competition from overseas led farmers to specialize and increase yields．Throughout this period food became cheaper, safe and more reliable．However, these changes have also led to habitat loss and to diminishing biodiversity．
What’s more, demand for animal products in developing countries is growing so fast that meeting it will require an extra 300 million tons of grain a year by 2050，yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions．
All this means that agriculture in the 21st century will have to be very different from how it was in the 20th．This will require radical（激进的）thinking．For example, we need to move away from the idea that traditional practices are inevitably more sustainable than new ones．We also need to abandon the notion that agriculture can be “zero impact”．The key will be to abandon the rather simple and static measures of sustainability, which centre on the need to maintain production without increasing damage．Instead we need a more dynamic interpretation, one that looks at the pros and cons of all the various way land is used．There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity．It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting, but we do not know whether lower carbon footprints will always be better for biodiversity．

Most of us spend our lives seeking the natural world. To this end, we walk the dog, play golf, go fishing, sit in the garden, drink outside rather than inside the pub, have a picnic, live in the suburbs, go to the seaside, buy a weekend place in the country. The most popular free time activity in Britain is going for a walk. And when joggers (慢跑者) jog, they don’t run the streets. Every one of them automatically heads to the park or the river. It is my firm belief that not only do we all need nature, but we all seek nature, whether we know we are doing so or not.
But despite this, our children are growing up nature-deprived (丧失). I spent my boyhood climbing trees. These days, children are robbed of these ancient freedoms, due to problems like crime, traffic, the loss of the open spaces and strange new ideas about what is best for children, that is to say, things that can be bought, rather than things that can be found.
The truth is to be found elsewhere. A study in the US: families had moved to better housing and the children were assessed for ADHD (多动症). Those whose housing had more natural views showed an improvement of 19%; those who had the same improvement in material surroundings but no nice view improved just 4%.
A study in Sweden indicated that kindergarten children who could play in a natural environment had less illness and greater physical ability than children used only to a normal playground. A US study suggested that when a school gave children access to a natural environment, the entire school would do better in studies.
Another study found that children play differently in a natural environment. In playgrounds, children create a hierarchy (等级) based on physical abilities, with the tough ones taking the lead. But when a grassy area was planted with bushes, the children got much more into fantasy play, and the social hierarchy was now based on imagination and creativity.
Most bullying (恃强凌弱) is found in schools where there is a tarmac (柏油碎石) playground; the least bullying is in a natural area that the children are encouraged to explore. This reminds me unpleasantly of Sunnyhill School, with its hard tarmac, where I used to hang about in corners dreaming about wildlife.
But children are frequently discouraged from involvement with natural spaces, for health and safety reasons, for fear that they might get dirty or that they might cause damage. So, instead, the damage is done to the children themselves: not to their bodies but to their souls.
One of the great problems of modern childhood is ADHD, now increasingly and expensively treated with drugs. Yet one study after another indicates that contact with nature gives huge benefits to ADHD children. However, we spend money on drugs rather than on green places.
The life of old people is much better when they have access to nature. The most important for the growing population of old people is in quality rather than quantity of years. And study after study finds that a garden is the single most important thing in finding that quality.
In wider and more difficult areas of life, there is evidence to indicate that natural surroundings improve all kinds of things. Even problems with crime and aggressive behaviour are reduced when there is contact with the natural world.
Dr William Bird, researcher from the Royal Society for the Protection of Birds, states in his study, “A natural environment can reduce violent behaviour because its process helps reduce anger and behavior that people might regret later.” Wild places need encouraging for this reason, no matter how small their contribution.
We tend to think human beings are doing nature some kind of favor when we are protecting nature. The error here is far too deep: not only do humans need nature for themselves, but the very idea that humanity and the natural world are separable things is damaging.
Human beings are a species of animals. For seven million years we lived on the planet as part of nature. So we miss the natural world and long for contact with non-human life. Anyone who has patted a dog, stroked a cat, sat under a tree with a glass of beer, given or received a bunch of flowers or chosen to walk through the park on a nice day, understands that.
We need the wild world. It is necessary to our well-being, our health, our happiness. Without other living things around us we are less than human.

Because earthquakes happen without warning, it’s important to take measures now to prepare. Because you don’t know where you will be when an earthquake happens, prepare some supplies for your home, workplace, and car.
1. Water
A person needs at least 1/2 gallon(加仑) of water daily just for drinking. Store at least 1 gallon of water per person per day and be prepared for a 72-hour period. It is suggested that you buy bottled water. Keep bottled water in its original container and do not open it until you need to use it. Also, do check the “use by” date.
2. Food
It’s always a practical idea to keep a supply of non-perishable(不易腐烂的) food on hand. Have an enough supply of canned food, powdered milk, dried fruits, non-salted nuts and canned juices for at least 72 hours.
3. Torch(手电筒) and spare batteries (电池)
Keep a torch beside your bed, at your place of work, and in your car. Do not use matches or candles after an earthquake until you are sure that no gas leaks(泄露).Prepare a battery-powered radio and spare batteries. Most telephones will be out of order, so radios will be your best source of information.
4. Clothes
If you live in a cold place, you must think about warmth. You might not have heat after an earthquake. Think about your clothing and bedding supplies.
1.Why should people prepare themselves for an earthquake?
A. Because earthquakes can be known before they happen.
B. Because earthquakes take place without warning.
C. Because earthquakes usually take place in the neighborhood.
D. Because it’s people’s daily work to prepare the earthquakes.
2.You should prepare all of the following except ______.
A. powdered milk B. fresh vegetables C. dried fruits D. canned juices
3.According to the article we know that ______.
A. we need to prepare some supplies only at home
B. a telephone is the most important prepared thing
C. after earthquakes you’d better use torch first but not matches
D. clothes are used to protect your head
4.If you live in a cold place, you should prepare _______.
A. some warm clothes and bedding supplies B. some hot water
C. some batteries D. some torches
In 1883, an imaginative engineer named John Roebling decided to build a spectacular bridge connecting New York with Long Island. However, bridge building experts throughout the world thought that this was a pipe dream. It was not practical. It had never been done before.
But Roebling refused to listen to them. He thought about the bridge day and night and he knew deep in his heart that it could be done. After much discussion and persuasion he convinced his son Washington, who was a promising engineer himself, that the bridge in fact could be built.
Working together for the first time, the father and son developed concepts of how it could be accomplished. With great excitement, they hired their crew and began to build their dream bridge.
The project started well, but several months after it began, a tragic accident on the site took the life of John Roebling. Washington was so seriously injured that he was never able to walk, talk or even move again.
"We told them so", "Crazy men and their crazy dreams", "It's foolish to chase wild visions", the critics said and most thought the project should be scrapped since the Roeblings were the only ones who knew how the bridge could be built. In spite of his handicap Washington still had a burning desire to complete the bridge and his mind was still as sharp as ever.
Washington's wife tried to inspire and pass on her husband's enthusiasm to some of his friends, but they were too daunted by the task. As he lay in his hospital room, an idea suddenly hit him. All he could do was move one finger and he decided to make the best use of it. By moving this finger and tapping it on his wife's arm, he slowly developed a code to communicate with her. Then he used this method to tell his wife what the engineers should do. It seemed crazy but the project was under way again. For 13 years Washington tapped out his instructions with his finger on his wife's arm, until the bridge was finally completed.
Today the spectacular Brooklyn Bridge stands in all its glory as a tribute to the triumph of one man's spirit and his determination not to be defeated by circumstances.
_ What did most people think about Roebling's idea to build the bridge?
A. It would never become a reality. B. Washington was not experienced enough.
C. It would take a lot of time. D. Finding the money would be impossible.
_The underlined word `daunted' (para. 6) is closest in meaning to '______'.
A. unpleasant B. scared C. amazed D. determined
_ Which of the following shows the correct order of the events that happened in the story?
a. Roebling convinced his son.
b. Washington found a new way to communicate.
c. They hired the crew.
d. The bridge was completed.
e. Roebling wanted to build a bridge.
f. There was a tragic accident.
A. e, a, c, f, d, b B. e, a, f, b, c, d C. e, f, a, b, c, d D. e, a, c, f, b, d
_ What can we learn about Washington's wife?
A. She knew sign language very well.
B. She was devoted to her husband.
C. She developed a code to communicate with her husband.
D. She helped her husband design the plan.
_ What does the story tell us?
