70年代以来，一些发达国家将重污染工业转到发展中国家．关于这一现象的说法，正确的是（　　）

Since the 70's, the US Chinese community has had the tremendous change Most remarkable is many comes from mainland Chinese not Duan Yongru the US, makes the American Chinese people's population to increase suddenly Along with the Chinese people population swift and violent increase with the Chinese race quality distinct enhancement, the Chinese people economy prospers day by day It is reported, from 1986, the American Chinese people economy leapt to head of the entire American national minority, leads to the date lineage, Han Yi and so on other descendants The American Chinese people family yearly average income has surpassed the American Caucasian family. At present, one group of Chinese people entrepreneurs enjoy the certain prestige in the American economy More encouraging is, in recent years US emitted one group of well-known people of Chinese descent scientists and technicians Their technical achievement has brought to the international scientific and technical circles attention and the admire Simultaneously Chinese people's political status distinct enhancement, steps in the American political circle person more and more many. 1. China successfully has carried on reform and open policy, has caused the giant echo in the world 2. In fact, that local peace is destructed, is precisely they evenly fords creates 3. West implementation big development strategy, speeds up the mid-west area the development, is China steps to the modernization third step of strategic target important deployment

解题思路：（1）高铁酸根（FeO₄^2-）在pH值为10～11时非常稳定，所以电解质溶液应该呈碱性；
（2）Fe电极反应式为Fe-6e^-+8OH^-═FeO₄^2-+4H₂O，C电极上氢离子放电；
（3）铁失电子和氢氧根离子反应生成高铁酸根离子．

（1）高铁酸根（FeO₄^2-）在pH值为10～11时非常稳定，当pH＜7.5时，稳定性明显下降，分解放出氧气，所以电解质溶液应该呈碱性，故选A；
（2）Fe电极反应式为Fe-6e^-+8OH^-═FeO₄^2-+4H₂O，C电极上氢离子放电生成氢气，所以看到的现象是铁电极附近溶液变为紫红色，石墨电极上有无色气体生成，铁电极变细，故答案为：铁电极附近溶液变为紫红色，石墨电极上有无色气体生成，铁电极变细；
（3）铁失电子和氢氧根离子反应生成高铁酸根离子，电极反应式为Fe+8OH^--6e^-=FeO₄^2-+4H₂O，故答案为：Fe+8OH^--6e^-=FeO₄^2-+4H₂O．

点评：
本题考点： 原电池和电解池的工作原理．

考点点评： 本题以制备高铁酸钾为载体考查了电解池原理，注意：活泼金属作阳极时，阳极上金属失电子而电解质溶液中阴离子失电子，阳极电极反应式的书写是学习难点，题目难度中等．

Since the 70's of the 20th century,the solar energy science and technology has progressed by leaps and bounds,the solar energy use changes with each new day,discussed shallowly the current solar energy technology utilization survey,the solar energy use's new product,introduced our country achievement and overseas some developed country solar energy utilization survey which obtains in the solar energy utilization aspect finally to solar energy technological progress forecast.

Since l970s, from the perspective of pragmatics of politeness phenomena have done a lot of research, published many thoughtful research results, this paper puts forward some wealthy effect of politeness theory. So far, the research of politeness is the most influential strange based on conversational maxims put forward with the politeness principle and brown and based on the face of the concept of levinson conversational implication "face management theory" or "face preservation theory". In discussing pragmatics concept, richie special emphasis on the function of context, but the politeness principle and pragmatic hierarchy is out of context, the key lies in the discourse of propositional content and expressions. He thinks discourse content by loss and whist decision, but the words of expression is refers to direct language and indirect language. This paper argues that propositional content and expression way at most can only decide language politeness, cannot decide discourse polite. Politeness is absolute, language from the context, do not have communicative price: discourse politeness is relative and dependent upon context, with communication value. Discourse polite absoluteness is opposite; Discourse polite relativity is absolute.
Pragmatic distance principle can be reasonably explain language use phenomenon, and solved the pragmatic circles long exist some fuzzy theoretical question, because mutual communication between the pragmatic distance, they are not necessarily the same in concrete communication process is sometimes polite (i.e. no manners or impolite). Politeness is communication between the two words of pragmatic distance is based on. Pragmatic distance principle that language manners in specific communication is also very important. Communication with a certain topic with the other communication, sensation and infers the with each other between the pragmatic intimate degree low, then language is necessary, but not polite particularly important. Discourse polite pragmatic distance principle requires us to best use polite language, so that the most effectively completed the current communication tasks. This paper is the tenet of lies
1.2 pragmatic distance characteristics
Discourse polite pragmatic distance principle, there are two basic concepts, Pragmatic distance and discourse polite. So-called pragmatic distance, refers to the communicators in specific events, with the aid of communication special language expression expression of each other's intimate degree. Any communicative behavior which used in the discourse are reflects communication between the two sides pragmatic distance. Pragmatic distance can be divided into former pragmatic distance and pragmatic application distance. Former pragmatic distance is communication occurs before by the communicator between presumption of perception and the pragmatic distance, Communicative language using distance is to point to in specific communication events in expressing the pragmatic to each other at a distance.
Pragmatic distance has two basic characteristics: changeability and can be the co ultation sex. So-called variability, refers to the pragmatic distance is constantly changing and not constant. Even in particular communication process, pragmatic distance rarely in constant state. So-called can the co ultation sex, refers to the pragmatic distance in verbal communication is can have a mutual communication consultation. Variability and co ultation sex pragmatic distance of distinctive features -- pragmatic distance and interpersonal relations and social distance between differences
