A、关闭所有的化工企业是不现实的，做法不可取；
B、用天然气取代民用燃煤，可以减少空气污染，做法可取；
C、污水先处理后排放，能防止水的污染．做法可取；
D、机动车辆的尾气污染是造成空气污染的主要原因之一，降低机动车辆的尾气污染．做法可取．
故选：A．

点评：
本题考点： 水资源的污染与防治；防治空气污染的措施．

考点点评： 环保问题已经引起了全球的重视，关于“三废”的处理问题和空气的污染问题，是中考的热点问题，当然垃圾处理也要考虑避免造成二次污染，化学上提倡绿色化学工艺，要从源头上杜绝污染．因此2008奥运会提出了“科技奥运、人文奥运、绿色奥运”的口号，提倡绿色化学，防止污染．

解题思路：（1）根据题中的叙述找出反应物、生成物书写方程式；
（2）首先列出方程式，根据题中的数据，列出比例关系进行求解．

（1）氢化钙和水反应生成氢氧化钙和氢气，故答案为：CaH₂+2H₂O=2H₂↑+Ca（OH）₂；
（2）875g氢化钙固体（含CaH₂96%）与足量水反应可生成
氢气的质量为X
CaH₂+2H₂O═2H₂↑+Ca（OH）₂
42 4
875g×96%x
[42/4]=[875×0•96/x]
x=80g
答：875g氢化钙固体（含CaH₂96%）与足量水反应可生成氢气的质量为80g．
故答案为：80g．

点评：
本题考点： 书写化学方程式、文字表达式、电离方程式；根据化学反应方程式的计算．

考点点评： 在解此类题时，首先根据题中的叙述书写方程式，然后根据方程式中的等量关系进行求解，需要注意代入方程式中的都是纯净物的质量．

平均每年绿地面的增加率是x
（1+x）（1+x）=1+44%
（1+x）² =1.44
1+x=1.2
x=0.2
x=20%
平均每年增加20%

B

热爱和自豪之情。

D

你好!这两个词汇虽然意思接近但并非重复,因为认可不一定就会支持,这就跟申办奥运会一个道理,2000年北京申办奥运会时,很多委员是认可北京的,但很多人最终还是选择了支持悉尼,所以只有“一致认可”+“广泛支持”才能获得申办……希望你能理解,谢谢!

解题思路：绿色化学，其核心是利用化学原理从源头上减少和消除工业生产对环境的污染；反应物的原子全部转化为期望的最终产物．绿色奥运是绿色化学的运用，利用新能源、节约用水等运用于奥运场馆的建设，符合绿色化学的理念．

A、将一些重污染工厂迁出市内，建立商业区或绿地，符合“绿色奥运”的理念，故不符合题意；
B、将烧汽油的汽车改造成烧清洁天然气的汽车，符合绿色奥运理念，故不符合题意；
C、兴建的大量体育馆充分利用太阳能或天然雨水，符合“绿色奥运”的理念，故不符合题意；
D、全北京市民努力学习外语，准备加入志愿者队伍，为奥运服务，与“绿色奥运”无关，故符合题意．
故选D．

点评：
本题考点： 防治空气污染的措施；常用燃料的使用与其对环境的影响．

考点点评： 本题考查绿色化学的理念，利用新能源等都符合绿色化学的理念．

病句为:北京申办奥运成功,我就萌发了学好外语,2008年去北京当个志愿者,为奥运服务.(不改变句子本身的意思)
改为:北京申办奥运成功,我就萌发了学好外语(的心愿),(到了)2008年去北京当个志愿者,为奥运服务.
病因:句子不通顺,缺少谓语

解题思路：空气污染的途径主要有两个：有害气体和粉尘．有害气体主要有一氧化碳、二氧化硫、二氧化氮等气体；粉尘主要指一些固体小颗粒．二氧化硫主要来源于煤、石油等化石燃料的燃烧，工厂排放的废气等，会引起酸雨，给农作物和建筑物造成很大的危害；因此我们采取的措施是：工厂废气经过处理后在排放；以自行车代替私家车；大量的植树造林；少放烟花爆竹等．

　　Dear :
　　Today, when the Olympic flame Ranran up, the people of the world's attention once again followed the attention Accor hundred years ago we could not help but recall the history of Zhuang King. 100 years after the world's people have once again gathered in this ancient culture and a sense of the land. This is friendship, peace, is fair and just competition in the sport of origin.
　　Then these 100 years, this great sport in the world and the source of transmission in the minds of people. The previous Olympic flame lit are accompanied by an atmosphere of unity and fraternity. The best of dazzling opening ceremony, the choice of tense moments, soul-stirring scene of the competition, large-scale Olympic event, the sweet green exotic scenery and warm hospitality of the people around, making the Olympics this term as the world's people are attention, love Nodal.
　　I even indulged in the glittering gold medal that light and lofty honor. I sincerely to the motherland and the people who brought all this glorious glory of the athletes who are proud of, more deeply for those who pay a lot of hard sweat and failed to obtain the medals to the athletes feel sorry about. Although there is only one gold medal, but they are heroes in my heart. As the opening ceremony of the Athens scene. The main lights off, the seats between the fluorescent light as bright as the star, a symbol of our star athletes such as focusing the Athens Olympics. I always close your eyes and recall the magnificent scene, they make this beautiful evening, I study them is an example.
　　Speaking of the Olympic Games, I still like to watch swimming and badminton, not only because these two are my strengths, but also because it from my life recently. I think one difficulty before swimming Society, and those athletes have to swim in just a few minutes of time travel a few hundred meters away, I do not know how many young reach of ordinary people have to pay unimaginable efforts, the number of flows difficult Sweat. The story behind the gold medal we may never countless. But we will not forget their names.
　　Now I am most excited and looking forward to the forthcoming 2008 in the capital of China - Beijing, convened the 29th session of the Games. I have long been the standard and the flag of the Olympic Games logo posted on the Qiangtou. I firmly believe that the people of the world it would be a gathering of the most memorable, a green and beautiful, culture and tradition of fairness and friendliness of the event, once this term to bring the Olympic Games even more far-reaching event. I would like to achieve this aim and to study hard and learn history, English and cultural practices, the future for the Beijing Olympics, let the world see a warm, civilized, beautiful, advanced Chinese.
　　I love the Olympics, and I look forward to the Olympics.

　　2008 Beijing Olympic Games will be full of wisdom; green.
　　2008 in Beijing, earthshaking changes have taken place: a Zhuangzhuang skyscrapers拔地而起; one of the wide road leading to all directions. World-class stadium, hotel, waiting for foreign friends visit. Piaozhuo the colored flags everywhere; has a wide variety of flowers of the open men, women and children singing and dancing…… ah, Beijing, the sea became joy.

　　Dear:
　　the year of 2008 is getting closer and closer to us. We need to take actions from now on to prepare for the game. What we need to do most is to work on our disadvantages and shortcomings. As a student of Senior high, I can do my own part. Although I can’t transform our city into more a beautiful place on my own, I can help Beijing in small ways and encourage our classmates and people around me to follow my lead.
　　Let me take the environment for example, the atmosphere around Beijing is quite disappointing, factories and cars keep giving off exhausts into the air, we can hardly see the blue sky with our naked eyes, because the sky is covered with a thick layer of harmful substances. The sky is gray instead of blue. To our delight, the government has passed some laws of protecting the air, and we can do something useful, too. For example, whenever we go out for a long distance, ride the bike or take the buses and subways instead of taxis. You may not have a clue how it works. Of course doing that only by one person is far from enough, but we can let more people do that together. In that case the result may be more than we bargained for.
　　Another thing we need to work on is our English skills. Teachers and parents often put great emphasis on our English skills especially listening and speaking. I want to be a volunteer in 2008, to be an interpreter. For now, I must do something helpful to improve my spoken English. Rome isn’t build in a day, so is English. It can’t be improved in a day or two. It takes time and energy. There are no shortcuts to improve your spoken English; the most productive way is to grab all opportunities around you to open your mouth. For instance, taking part in all kinds of English contests is a good way, you can meet some excellent contestants, and you can share the experience of learning and some good method of learning. I will keep participating in all English activities to polish up my English. I’m sure by the year of 2008, I will be able to master English well just as my mother tongue.
　　All in all, I’m sure that Beijing Olympic Games will be one of the most successful Games in history. I believe our long-cherished dream will be fulfilled in a perfect way!

　　2008年奥运会和我
　　2008年离我们越来越近了,我们必须从现在开始采取行动,来为奥运会做准备.我们最需要做的,是克服缺点和改进不足之处.作为一名高中生,我们可以做我们力所能及的事情.虽然我不能光靠我自身的力量把这座城市妆点得更美丽,但我可以用自己的方式,来改变北京并且鼓励我的同学们和我周围的人和我一起做.
　　让我以环境为例,北京周围的大气环境比较令人失望,工厂和汽车不断地向空中排放废气,我们几乎用肉眼看不到蓝色的天空了.因为天空被一层厚厚的有害物质所覆盖, 天空成了灰色,而不是蓝色.令我们高兴的是,政府已经出台一些保护大气环境的相关法规.我们呢,也可以做一些有用的事情.比如说,每当我们要出远门的时候,骑自行车或乘坐公交车和地铁来代替出租车.你可能不知道这会有什么用.当然,只靠一个人的力量是远远不够的,但是我们可以让更多的人一起去做. 这样的话,结果才有可能收效显著.
　　我们需要做的另一件事,是提高我们的英语水平.老师和家长总是着重强调要提高我们的英语能力,尤其是听力和口语方面,在2008年,我想成为一名志愿者,做一名口语翻译.现在我必须做一些有助于提高我口语的事情.“罗马非一日建成”,英语也不可以在一、两天内得到提高.它需要花费很多的时间和精力,在提高口语方面,没有捷径可走,最有效的方式就是抓住身边的机会开口讲英语.比如：参加各种英语竞赛是一种很好的方式.你会遇到些非常优秀的选手,与他们交流学习体会,借鉴好的学习方法.我将继续参加各类英语活动,来提高我的口语能力.我相信在2008年,我将会像掌握母语一样熟练掌握英语.
　　总之,我相信,2008北京奥运会将是有史以来最出色的奥运会之一,我坚信,我们长时间以来的梦想会以完美的方式得以实现
