8．In a world with limited land，water and other natural resources （资源），the harm from the traditional business model is on the rise．Actually，the past decades has seen more and more forests disappearing and globe becoming increasingly warm．People now realize that this unhealthy situation must be changed，and that we must be able to develop in sustainable （可持续的） ways．That means growth with low carbon or development of sustainable products．In other words，we should keep the earth healthy while using its supply of natural resources．
Today，sustainable development is a proper trend in many countries．According to a recent study，the global market for low-carbon energy will become three times bigger over the next decades．China，for example，has set its mind on leading that market，hoping to seize chances in the new round of the global energy revolution．It is now tryuing hard to make full use of wind and solar energy，and is spending a huge amount of money making electric cars and high-speed trains．In addition，we are also seeing great growth in the global markets for sustainable products such as palm oil （棕榈油），which is produced without cutting down valuable rainforest．In recent years the markets for sustainable products have grown by more than 50%．
Governments can fully develop the potential of these new markets．First，they can set high targets for reducing carbon emissions （排放） and targets for saving and reusing energy．Besides，stronger arrangement of public resources like forests can also help to speed up the development．Finally，governments can avoid the huge expenses that are taking us in the wrong direction，and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one．
The major challenge of this century is to find ways to meet the needs of growing population within the limits if this single planet．That is no small task，but it offers abundant new chances for sustainable product industries．
41．The traditional business model is humful because of all the following EXCEPT thatD．
A．It makes the world warmer
B．it consumes natural resources
C．it brings severe damage to forests
D．it makes growth hard to continue
42．What can we infer from Paragraph 2？C
A．China lacks wind and solar energy．
B．China is the leader of the low-carbon market．
C．High-speed trains are a low-carbon development．
D．Palm oil is made at the cost of valuable forests．
43．To full develop the low-carbon markets，government canD．
A．cut public expenses
B．forbid carbon emission
C．develop public resources
D．encourage energy conservation
44．We can learn from the last paragraph that businesses have many chances toA．
A．develop sustainable products
B．explore new natural resources
C．make full use of natural resources
D．deal with the major challenge
45．What is the main purpose og the passage？D
A．To introduce a new business model．

分析 在这个土地、水和其它自然资源都有限的世界，来自传统商业模式的危害正在呈上升趋势．实际上，在过去几十年里已经看到有越来越多的森林消失，地球急剧变暖．现在人们认识到，这种不良的状况必须改变，而且我们必须采取某些可持续的方式发展．这意味着要增长低碳或可持续产品的发展，换句话说，我们在使用自然资源的同时应该让地球保持良好状态．
今天，可持续发展在许多国家是一个合理的趋势．根据最近的一项研究显示，在未来的几十年里，全球低碳能源的市场将扩大三倍．例如，中国已下定决心去引领市场，在这次全球能源革新中抓住机会．现在正在努力充分利用风能和太阳能，正在花巨资制造和使用电动汽车和高速列车．此外，我们可以看到全球市场上可持续产品的巨大增长，例如，在没有削减宝贵雨林的情况下制造的棕榈油．近年来，市场上可持续产品的增长已超过50%．
政府能够充分开发潜在的新市场．首先，他们能设立降低碳排放的目标，以及节约能源和再利用能源的目标．此外，采取强制措施加速发展像森林这样的公共资源．最后，政府可以避免我们错误的进行巨大消费，指导其中的一些消费从传统模式向可持续模式加速转变．
本世纪最主要的挑战是在我们这个唯一的星球限制内寻找方法满足正急剧增长的人口的需求．这绝非小任务，它要为可持续发展工业提供充足的新机会．
解答 答案；
41．D 推理判断题． 根据第一段 Actually，the past decades has seen more and more forests disappearing and globe becoming increasingly warm 实际上，在过去几十年里已经看到有越来越多的森林消失，地球急剧变暖．"可知，A．B．C表述的内容是正确的；故选D
42．C 细节推理题 通读第二段可知，根据"China，for example，has set its mind on leading that market中国已下定决心去引领市场"并不是说"B．中国是低碳市场的领导者"；根据"It is now tryuing hard to make full use of wind and solar energy（中国）现在正在努力充分利用风能和太阳能"可知，并没有说"中国缺少风能和太阳能"故A不正确；根据"In addition，we are also seeing great growth in the global markets for…without cutting down valuable rainforest．此外，我们可以看到全球市场上可持续产品的巨大增长，例如，在没有削减宝贵雨林的情况下制造的棕榈油，"可知，"D．制造的棕榈油是以珍贵的森林为代价的．"是不正确的．故选C
43．D 细节理解题 根据第三段"Governments can fully develop the potential of these new markets．First，they can set high targets for reducing carbon emissions…政府能够充分开发潜在的新市场．首先，他们能设立降低碳排放的目标，以及节约能源和再利用能源的目标…"可知，"D．鼓励节能"和文中意思相符，故选D
44．A主旨大意题 通读最后一段可知，本段主要讲述了本世纪主要的挑战要为可持续发展工业提供充足的新机会．故选A
45．D 主旨大意题．通读全文可知，第一段是本文的中心段，它表达了传统的商业模式带来的危害，因此需要转变商业模式，增长低碳或可持续产品的发展．"D．提倡可持续发展"故选 D．
