Questions 31 to 35 are based on the following passage. In a rapidly changing world there is a growing awareness that we are facing major problems. In spite of all the economic growth of the last forty years, the gap between the richest 1.5 billion and the majority of the world’s people is actually growing, with over a billion people in deep poverty and many hundreds of millions more living on the margins( 边缘 ). Moreover, as the world’s population passes the 7 billion mark, it is obvious that we are fast approaching the limits f the global environment to cope with human activity. Responding to challenges such as climate change and food insecurity are just two of the key issues of our time. In such an era – of an increasingly divided world --- the need for gradual social change is obvious. Indeed, unless we can adapt creatively, prospects for a peaceful and stable world will rapidly fade. This is where Network tries to make a difference. It approaches these issues in a spirit of optimism and commitment and seeks continuously to support creative thinking and enterprising( 大胆的 ) projects. It often identifies those ideas that really do look ahead but find it difficult to get support from ordinary sources. The 2010s will be the decade that does much to determine how peaceful the world will be for the next half century. We have the ability to work towards a more sustainable( 可持续的 ) and liberated society but it will require creativity and courage – and financial support. Prophecy is sometimes defined as “suggesting the possible”, as positive thinking and action for a better world. That is where Network comes in.
