Leading scientists have joined the growing chorus of concern （worry） about governments and companies rushing into producing biofuels （生物燃料） as a solution for global warming，saying that it could be harmful if they do not consider the long-term influence of what they are doing carefully．
It is necessary to build standards for the supply system of any green fuel project in order to make sure that there aren't any side effects on the environment and social structures．The report produced by the scientists expresses concern that many companies may not be fully aware of the possible disadvantages．
Production of crops （农作物），such as corn and soya beans，has increased greatly in the last few years as another eco-friendly choice to natural fuels，but environmental and human rights movement leaders are worried that this will lead to destruction （破坏） of rain forests．Food prices could also go up as there is increasing competition for crops as both food and sources of fuels．Last week，the UN warned that biofuels could have dangerous side effects and said that steps need to be taken to make sure that land chosen to grow biofuels does not damage the environment or social structures．There is already great concern about palm oil （棕榈油），which is used in many foods in addition to being an important biofuel，as rain forests are being cleared in some countries and people driven from their homes to plant more palms．
The report suggests that biofuels are not a solution for climate change but they can play their part as long as governments and companies manage the social and environment influence thoroughly．There should also be greater measures （措施） taken to increase the effectiveness and to reduce needs．
58．The underlined phrase"side effects"probably means___．
A．improving conditions
B．unwanted results
C．increasing influences
D．unchanged advantages
59．The third paragraph is mainly about___．
A．the danger of rain forests
B．the warning given by the UN
C．the green biofuels liked by people
D．the possible disadvantages of biofuels
60．What can we infer from the passage？___
A．The development of biofuels will probably influence people's daily life．
B．Greater measures should be taken to reduce the amount of biofuels．
C．Almost all the companies are worried about the future of biofuels．
D．Rain forests are being cleared to grow more palms as biofuels．
优质解答
58．B 词义猜测题，根据第二段It is necessary to build standards for the supply system of any green fuel project in order to make sure that there aren't any side effects on the environment and social structures可知应该为绿色燃料项目的供应体系建立标准，确保没有任何的副作用，由此可知"side effects"指的是我们不希望发生的结果，故选B．
59．D 细节理解题，根据第三段biofuels could have dangerous side effects and said that steps need to be taken to make sure that land chosen to grow biofuels does not damage the environment or social structures可知生物燃料可能对我们有副作用，我们需要采取措施来确保种植生物燃料的土地不破坏环境和社会结构，由此可知本段讲述的是生物燃料的缺点，故选D．
60．A 推理判断题，根据第三段Last week，the UN warned that biofuels could have dangerous side effects and said that steps need to be taken to make sure that land chosen to grow biofuels does not damage the environment or social structures．可知生物燃料可能对我们有副作用，我们需要采取措施来确保种植生物燃料的土地不破坏环境和社会结构，由此推知生物燃料的发展可能会影响人们的日常生活，故选A．
