Question

ÔĶÁÀí½â ¡¡¡¡A Low£­Carbon Economy(LCE)or Low£­Fossil£­Fuel Economy(LFFE)is an economy which has a smallest output of greenhouse gas(GHG)release into the atmosphere, but specifically refers to the greenhouse gas CO2£®Recently, most of scientific and public opinion has come to the conclusion that there is such an accumulation of GHG(especially CO2)in the atmosphere due to human£­related activities that the climate is changing£®The over£­concentration of these gases is producing global warming that affects long£­term climate, with negative impacts on humanity in the foreseeable future£®Globally performed LCEs therefore, are proposed as a means to avoid catastrophic climate change, and as a forerunner to the more advanced, zero£­carbon society and renewable£­energy economy£® ¡¡¡¡Some nations are low£­carbon societies which are not heavily industrialized or populated£®In order to avoid climate change at any point in the future, all nations considered carbon£­thick societies and societies which are heavily populated, should become zero£­carbon societies and economies£®Several of these countries have promised to become ¡°low carbon¡± but not entirely zero carbon, and claim that release will be cut by 100£¥ by offsetting release rather than stopping all release£®In other words, some release will continue which will be offset, so they are not low£­release£® ¡¡¡¡Nations seek to become low£­carbon economies as part of a national global warming reductionstrategy£®A comprehensive strategy to manage global warming is carbon neutrality, geoengineering andadaptation to global warming£® ¡¡¡¡Nuclear power, or, the proposed strategies of carbon collection and storage(CCS)have been proposed as the primary means to achieve a LCE while continuing to exploit non£­renewable resources; there is concern, however, with the matter of spent£­nuclear£­fuel storage, security and the uncertainty of costs and time needed to successfully carry out CCS worldwide and with guarantees that the stored release will not leak into the atmosphere£®Alternatively, many have proposed renewable energy should be the main basis of a LCE, but, they have their associated problems of high£­cost and inefficiency; this is changing, however, since investment and production have been growing significantly in recent times£®Furthermore, regardless of the effect to the atmosphere by GHG releases, the growing issue of peak oil may also be reason enough for a change to a LCE£® [½âÌâµ¼Óï]ΪÁ˱£»¤»·¾³£¬½ÚÔ¼×ÊÔ´£¬ÎÒÃÇÓ¦¸ÃʵÐÐеÄÉú»î·½Ê½£¬Ò²¾ÍÊÇÎÄÕÂÖÐËù½éÉܵĵÍ̼Éú»î¡£ (1) Low£­carbon economy is encouraged for the following reasons except that ________£® [¡¡¡¡] A£® too much greenhouse gas CO2 is released B£® the over£­concentration of greenhouse gases is producing global warming C£® it can avoid catastrophic climate change D£® low carbon and zero carbon nations and societies claim for it (2) The underlined word in the first paragraph probably means ________£® [¡¡¡¡] A£® warning B£® pioneer C£® symbol D£® guide (3) According to the passage, which of the following is NOT true?
