4．The World Health Organization warns that millions of people are dying every year from indoor air pollution．Nearly three billion people are unable to use clean fuels and technologies for cooking，heating and lighting．
These findings show that the use of deadly fuels in inefficient stoves，space heaters or lights is to blame for many of these deaths．
WHO officials say indoor pollution leads to early deaths from stroke，heart and lung disease，childhood pneumonia and lung cancer．Women and girls are the main victims．These diseases can often result from the burning of solid fuels．These fuels include wood，coal，animal waste，crop waste and charcoal．
The United Nations found that more than 95percent of households in sub-Saharan Africa depend on solid fuels for cooking．It says huge populations in India，China and Latin American countries，such as Guatemala and Peru，also are at risk．
Nigel Brace is a professor of Public Health at the University of Liverpool．He says researchers are developing good cook-stoves and other equipment to burn fuels in a more efficient way．There are already multiple technologies available for use in clean fuels．There is really uite an effective and reasonably low-cost alcohol stove that is made by Dometic（a Sweden-based company）that is now being tested out．LPG （liquified petroleum gas）cook is obviously widely available and efforts are under way to make those efficient．Another interesting development is electric induction stoves（電磁爐）．WHO experts note some new，safe and low-cost technologies that could help are already available．In India，you can buy an induction stove for about 8.00．And in Africa you can buy a solar lamp for less than 1.00．
But，this，the agency says，is just a start．It is urging developing countries to use cleaner fuels and increase access to cleaner and more modern cooking and heating appliances．

分析 本文屬于記敘文閱讀，作者通過這篇文章向我們講述了世界衛生組織說，每年有數百萬人死于室內空氣污染，并列舉了一些例子，說明發展中國家的人死亡人數更多，如今研究人員正在開發清潔燃料．
解答 32．A 細節理解題，根據第二段These findings show that the use of deadly fuels in inefficient stoves，space heaters or lights is to blame for many of these deaths．可知室內空氣污染來自于可以致命的燃料，故選A．
33．C 推理判斷題，根據第三段Women and girls are the main victims．These diseases can often result from the burning of solid fuels．These fuels include wood，coal，animal waste，crop waste and charcoal．可知這一段是通過列舉的方式敘述的，故選C．
34．B 推理判斷題，根據第四段It says huge populations in India，China and Latin American countries，such as Guatemala and Peru，also are at risk．可知在中國，印度，和拉丁美洲的國家的人們存在風險，因此可以推斷大多數的死亡發生在發展中國家，故選B．
35．D 細節理解題，根據倒數第二段In India，you can buy an induction stove for about 8.00．And in Africa you can buy a solar lamp for less than 1.00．可知非洲的太陽能燈很便宜，故選D．
點評 考查學生的細節理解和推理判斷能力．做細節理解題時一定要找到文章中的原句，和題干進行比較，再做出正確選擇．在做推理判斷題時不要以個人的主觀想象代替文章的事實，要根據文章事實進行合乎邏輯的推理判斷．
