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．

Are you an optimist? Do you look at your glass and see it as half full? Do you believe that every cloud has a silver lining and that things generally turn out for the best? Do you believe that if something is meant to be, it will be? If you reply “yes” to all of these questions, then you are an optimist. You probably are enthusiastic, cheerful and outgoing. You may be successful at work and in love.

But you may be misguided because things don’t turn out for the best. You may believe that when one door closes another one opens (for example, you may fail to obtain a new job; another chance will come around soon). Wrong. When one door closes, another door slams (砰然关上) in your face. That’s bitter reality.

Now a book has been published which confirms what pessimists (悲观者) have suspected all along. It’s called The Positive Power of Defensive Pessimism. Its author argues that defensive pessimism can lead to positive results. Defensive pessimism is a strategy used to manage fear, anxiety and worry. Defensive pessimists prepare for the things by setting low outcomes for themselves. They carefully consider everything that may go wrong and plan for ways to handle these problems. And this gives them a sense of control. Lawrence Sanno, a psychology professor, says, “What’s interesting about defensive pessimists is that they tend to be very successful people, so their low opinion of the situation’s outcomes is not realistic. They use it to motivate themselves to perform better.”

So far, so good. This is not rocket science. Defensive pessimists prepare carefully and consider what might go wrong, whether at work, on date or even in a sports game. It makes sense to have a back-up plan. There are many sayings in English urging caution. For example, “Don’t put all your eggs in one basket.” And “Don’t count your chickens until they hatch.” To have a confident and optimistic approach to life’s problems is good. But listen to what Woody Alien, the American comedian says, “Confidence is what you have before you understand the problem.”

There are pros and cons to being an optimist and a pessimist. Don’t feel bad if you see the glass half empty. You are a realist. But lighten up and hook up with someone who sees the same glass half full.

1.What’s the passage mainly about?

A. A book that has recently been published.

B. How to become successful in life.

C. The dangers of being too optimistic.

D. The benefits of defensive pessimism.

2.The underlined sentence “This is not rocket science” (Para. 4) means __________.

A. it’s not a dangerous thing to do

B. it is quite simple to understand

C. the cost is not so high

D. there is no real proof

3.Which of the following English expressions would a defensive pessimist believe?

A. Don’t put all your eggs in one basket.

C. Whatever will be, will be.

D. Every cloud has a silver lining.

4.The writer would probably describe himself as __________.

A. an optimist B. a defeatist C. a realist D. a scientist
