血型与性格的关系是人们津津乐道的话题,但这种关联性此前并未得到学术上的充分论证。韩国一项最新研究结果显示,O型血的人比较外向,而A型血的人相对内向。韩国联合通讯社9月21日报道,韩国延世大学研究人员刘圣益和孙荣宇在综合分析以往的血型类型学研究成果后认为,A型血的人逻辑性较强,并且比较稳重,而B型血与其他血型相比比较感性。刘圣益说,比起A型和AB型,B型血的人比较外向;但与O型相比,B型血相对内向。两名研究者强调,一个人的性格取决于各种遗传特性和环境因素的综合作用,不能盲目根据血型判断性格类型。

     Leading investors have joined the growing chorus of concern about governments and companies

rushing into producing biofuels as a solution for global warming, saying that many involved in the sector

could be jeopardizing future profits if they do not consider the longterm impact of what they are doing

carefully.

     It is essential to build sustainability criteria into the supply chain of any green fuel project in order to

ensure that there is no adverse effect on the surrounding environment and social structures.The report

produced by the investors expresses concern that many companies may not be fully aware of the potential pitfalls in the biofuel sector.

     Production of corn and soya beans has increased dramatically in the last years as an ecofriendly

alternative to fossil fuels but environmental and human rights campaigners are worried that this will lead to

destruction of rain forests.Food prices could also go up as there is increased competition for crops as both foodstuffs and sources of fuel.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 converted to grow biofuels does not damage

the environment or cause civil unrest.There is already great concern about palm oil, 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 create palm oil plantations.

     An analyst and author of the investors'report says that biofuels are not a cure for climate change but

they can play their part as long as governments and companies manage the social and enviromental

impacts thoroughly.There should also be greater measures taken to increase efficiency and to reduce

demand.
