Ⅰ.阅读理解 Human demands fr natural resurces have dubled in less than 50 years and are nw beynd what the earth can prvide,a reprt warned.If humans carry n like this,we will need tw earths by 2030.The ppulatin f wildlife has fallen by 60% in thirty years. The reprt said British peple are cnsuming (消耗) far mre than the earth can deal with.If everyne lived such a lifestyle,humans wuld need 2.75 planets t survive.Peple are nw living lifestyles which wuld require 1.5 planets,thugh there are great differences between rich and pr natins.
Researchers studied the glbal change in land use and water cnsumptin.The UK cmes the 31st in a list f cuntries based n “eclgical ftprint (生态足迹)” that measures hw much land and sea each persn needs t prduce the resurces they cnsume and t absrb (吸收) the wastes.The UK has fallen dwn frm the 15th place in the last reprt tw years ag t the 31st place,but the WWF believes it is an increase in ther cuntries’ effrts rather than a reductin in the UK’s use f resurces.
Ireland has the 10th highest eclgical ftprint,while the United Arab Emirates,Qatar,Denmark,Belgium and the US are the five wrst cuntries fr ver-cnsumptin f resurces.The study suggests if the expected glbal ppulatin f 9.2 billin in 2050 were t eat a Malaysian diet,1.3 planets wuld be needed but if everyne were t eat an Italian diet,humans wuld need almst tw planets.Thse cuntries that can prvide the highest quality f life using the lwest amunt f resurces will nt nly serve the glbal interest,but will be the leaders in a resurce-limited wrld.语篇导读:本文为一篇说明文,讲述人类在透支地球的资源。阅读本文有利于培养学生的环境保护意识。
