Question

閱讀下面的材料，然后根據材料內容回答問題。
What is to blame（歸咎于） for the smog (霧霾) hitting China? The question that has bothered people for a long time got an answer recently.
According to Wang Yuesi, a researcher at the Chinese Academy of Sciences (CAS), about 40 percent of PM2.5 pollutants in Beijing are the result of coal (煤炭) burning, from both local and outside the city.
Surrounded by Hebei, a major area for coal burning, about 20 percent of Beijing’s pollutants come from outside the city. And we know there are many steel(鋼鐵) factories in Hebei, too. According to the CAS, each year Beijing burns 23 million tons of coal while Tianjin burns more than 70 million tons and Hebei a huge 270 million tons.
“Coal burning is a primary source of sulfur oxide (SO2, 二氧化硫) which is the primary cause of PM2.5,” said Wang.
The report of the CAS says that in the Jingjinji area (Beijing, Tianjin and Hebei), coal burning is responsible(負責任的) for 9 percent of primary particles (顆粒) that make up PM2.5. The coal burning also emits (排放) 69 percent of the total SO2 and 47 percent of nitrogen oxide (氮氧化物), which will greatly concentrate (加強濃度) the PM2.5 particles in the air.
According to the air pollution plan, the Jingjinji area should reduce（減少） its PM2.5 concentration by 25 percent by 2017 from 2012 levels. To meet the standards, the report suggests great cuts in coal use in the area.
“This is a very great goal but it is achievable with cooperation（合作） between cities instead of cities working on their own,” said Wang.

Answer 1

小題1:（It is the result of） Coal burning.
小題2:Yes, we can.
小題3:SO2./Sulfur oxide.
小題4:Because it is a major area for coal burning and there are many steel factories there.
小題5:Wang Yuesi.

試題分析：本文通過中國科學院院士王躍思的一篇，關于北京霧霾天氣的產生原因分析報告引入。接著介紹了霧霾天氣中含有害成份，以及如何去處理這種現象的產生，并且提出解決辦法及建議。最后要求每個城市都要進行合作，在合作中去共同治理環境。
小題1:細節理解題。問題：在北京引起霧霾的主要原因是什么？分析原文：about 40 percent of PM2.5 pollutants in Beijing are the result of coal (煤炭) burning, from both local and outside the city.句意：北京約40%的PM2.5污染是煤炭燃燒的結果，這包括從本地和周圍的城市過來的。明確指出了產生這種天氣的主要原因。故填：（It is the result of） Coal burning.
小題2:細節理解題。問題：通過城市之間的合作能解決這個問題嗎？分析原文：This is a very great goal but it is achievable with cooperation（合作） between cities instead of cities working on their own。句意：這是一個偉大的目標，通過城市之間的合作是可以完成環境治理的。從這句話中體現出了答案是肯定的回答。故填：Yes, we can.
小題3:細節理解題。問題：引起PM2.5的主要原因是什么? 分析原文：“Coal burning is a primary source of sulfur oxide (SO2, 二氧化硫) which is the primary cause of PM2.5. 句意：燒煤后的污染物的主要成份是二氧化硫。故填：SO2./Sulfur oxide.
小題4:細節理解題。問題：為什么河北會有很多PM2.5污染?分析原文：we know there are many steel(鋼鐵) factories in Hebei. 句意：我們知道有很多鋼鐵工廠在河北。聯系上下文PM值的產生是煤炭燃燒的結果，而這些鋼鐵廠，每天都要燃燒大量的煤。故填：Because it is a major area for coal burning and there are many steel factories there.
小題5:細節理解題。問題：中科院的誰宣布調查結果?分析原文：According to Wang Yuesi, a researcher at the Chinese Academy of Sciences (CAS)句意：中國科學院研究員王躍思的一份報告。從而明確宣布人的姓名。故填：Wang Yuesi.
