Ecological criticism is produced in the nineteen seventies a theory of literary criticism. In the early 70's publication of the" survival Drama : literary ecology" in one book, American scholar Joseph Smith, Kerr puts forward " literary ecology" ( Literary Ecology ) is a term, advocates should explore the literature revealed by human and other relationships between species, should be careful and sincerely look and explore the literature on human behavior and the influence of the natural environment. In 1978, William Lu Keer in" Iowa review" Ninth issue entitled" literature and Ecology: an experimental" article, first used the " ecological criticism" ( ecocriticiam ) of this concept, consider ecology and ecological concepts relevant to use literature research in. Thereafter. The rapid development of ecological criticism, and aroused the extensive attention. To 90 time, ecological criticism has gradually become a theory of literary criticism theory.At present, the academic concept of ecological criticism which is widely used in American literature and the environment of Professor Cherry 's glotfelty under the definition of ecological criticism," is the study of the relationship between literature and the physical environment, ... ... According to the center of the earth for staff to study literature". The former can be regarded as the object of ecological criticism, literature and the physical environment ( NATURAL ) relationship as the object of study; the latter is intended to illustrate the research method," take the earth as the center to study literature" can be understood as the station in the earth's ecological standpoint to study literature, discussing the relation between man and nature, creation more ecological literature, arouse people to protect the ecological environment consciousness, so as to construct a more reasonable ecological philosophy.Ecological criticism in post modern context, belongs to the modern criticism and theory, by the deconstruction thought influence, it challenges, expose, criticizing the" logos centralism", digestion, subversion of the traditional. Ecological criticism against the" logos centralism" performance "of anthropocentrism". "The human center principle" is the mainstream western philosophy since the modern cultural values," Modernity" is one of the important features of. It is with person and nature of the binary opposition between the two as the premise, claims that man is the master of nature, the center of the world, has the supreme right; nature is human rule, control object, nature as" others" no" intrinsic value". " Talent is everything of value subject, is the creator of all values and commitment". This is an absolute" Anthropocentrism" values, it will be in the world extremely elevated position, emphasize the subjectivity of man, serious and screwy person and natural ecological relationship between reasonable. Such values in human productivity level is not high, the human activities are not sufficient to constitute a great threat to natural history has played a positive role, promoting the progress of human civilization. Then, latter-day since the Renaissance, there has been Bacon's" command nature", Descartes " to become the master of nature and the ruler" and Kant's" human is the nature of the lawmakers" and so on" doctrine of human center" the outstanding expression of thought, it also shows that the modern" Anthropocentrism" thought formation.

真理总是掌握在少数人手里的

中东国家大幅度提高石油价格.
C肯定不对,资本主义世界的无产阶级贫困是长期存在问题,而且当时资本主义世界推行福利国家政策,所以C不对,应该是B.
那么为什么中东国家要大幅度提高石油价格呢?
石油作为一种重要的能源,自70年代起开始取代煤炭,成为世界能源消费的主要部分.石油的生产和消费极不平衡,美国、欧洲和日本所生产的石油不到全球总产量的20%,其石油消费量却占全球总消费量的70%,不得不大量依靠进口,石油价格的变动直接影响全球经济的表现.
中东国家是主要的石油生产国,1960年9月,第三世界石油生产国建立了石油输出国组织（OPEC）,致力于改变长期形成的油价过低的不合理局面.70年代起,OPEC成员国通过参股和收归国有等措施,逐步掌握了自己的石油资源.
70年代初美元汇率下调,西方工业国的制成品价格相应上涨,由于石油贸易以美元计价结算,石油出口收入跟随美元汇率持续下降,石油生产国蒙受重大损失.1973年10月中东战争爆发后,OPEC成员国一方面加快石油生产国有化进程,另一方面大幅度提高石油价格,石油价格从此前的每桶3.01美元提高到1974年1月的11.65美元.1979年1月,OPEC再度提高油价,把每桶原油定价调整为14.327美元,到1981年10月,国际市场油价上升到每桶34美元.
石油价格的大幅度上升对世界经济产生了重大影响,尤其是严重依赖石油进口的经济体遭受了严重的外部冲击,国际金融市场主要货币汇率的灵活调整为这些经济体吸收这种外部冲击提供了可能.持续三年的石油危机对发达国家的经济造成了严重的冲击.在这场危机中,美国的工业生产下降了14%,日本的工业生产下降了20%以上,从而触发了第二次世界大战之后最严重的全球经济危机.

不可取.因为采用高烟囱只是将烟和废气排在了高空大气层中,同样是排在了大气层中,对大气层的污染也是同样的,不能从根本上解决这一问题,所以此方法不可取.

In the 1970s, bills, currency in stocks, bonds, the basic financial instruments on the basis of derived financial derivatives rise, innovation. Because it has extensive in small and avoid the risk of financial leverage, has become a financial risk evasion field, and seek hedging speculative yields important tool, which has caused a series of shocked the world's financial crisis. Therefore, the development of financial derivatives caused extensive concern of the world. And how to record, measurement, analysis and supervision of financial derivatives of the risks and benefits of accounting problems become financial accounting theory and practice research focus.
This article mainly from the financial derivatives, the accounting information disclosure of accounting measurement and three facing financial derivatives accounting problems are discussed. From the first derivatives, combined with the feature of concept and criteria for research institutions, must develop traditional accounting theory of assets and liabilities of the definition of financial derivatives, solve the problem discussed, belonging to the financial derivatives accounting issues lays the foundation. Then based on international accounting standards board and the financial accounting standards board related provisions of the introduction and analysis, puts forward the financial derivatives in accounting recognition in principle to insist on the initial confirmation, follow-up confirmation and termination of three steps that in accounting measurement attribute, insist on financial derivatives are fair value measurement attribute of the related. In addition, this paper studies the derivative products report information disclosure. Finally, according to the facts, how to effective implementation of financial derivatives in accounting Suggestions or thinking.
Keywords: financial derivatives, accounting, and accounting measurement confirmation, the information disclosure

解题思路：1、肺炎双球菌转化实验包括格里菲斯体外转化实验和艾弗里体内转化实验，其中格里菲斯体内转化实验证明S型细菌中存在某种“转化因子”，能将R型细菌转化成S型细菌；艾弗里体外转化实验证明DNA是遗传物质．
2、特异性免疫包括体液免疫和细胞免疫，其具体过程如下：

（1）S型细菌中存在某种“转化因子”，能将部分R型细菌转化成S型细菌，因此，在实验4中死亡的小鼠中能够分离出S型和R型细菌．
（2）S型细菌的特点：含有多糖类的荚膜、有毒性、菌落光滑，而R型细菌的特点：无多糖类的荚膜、无毒性、菌落粗糙．因此，除了用上述注射法，通过观察小鼠的生活情况来判断R型和S型细菌外，你还可以通过显微镜下观察细菌有无荚膜或在固体培养基中培养，观察菌落特征，若表面光滑，则为S型；若菌落表面粗糙，则为R型细菌．
（3）绘图时需要注意：①曲线的初始数量应为0，体现转化从无到有的过程；②S型细菌种群将呈现“S”型增长；③S型细菌的曲线应先于R型细菌曲线开始增长，且最后数量要高于R型细菌．如图：

（4）该实验的结论是：S型细菌中存在着某种“转化因子”，能将R型细菌转化为S型细菌．
（5）实验3小鼠注射过程加热杀死的S型细菌，而加热杀死的S型细菌相当于疫苗，刺激小鼠产生大量的抗体和记忆细胞，因此一段时间后，给实验3中的小鼠再次注射S型细菌，该小鼠存活．
故答案为：
（1）S型和R型
（2）显微镜下观察细菌有无荚膜或在固体培养基中培养，观察菌落特征，若表面光滑，则为S型；若菌落表面粗糙，则为R型
（3）如图
绘图时需要注意：①S型细菌种群将呈现“S”型增长；②曲线的初始数量应为0，体现转化从无到有的过程；③S型细菌的曲线应先于R型细菌曲线开始增长，且最后数量要高于R型细菌．
（4）S型细菌中存在着转化因子
（5）存活　加热杀死的S型细菌相当于疫苗，刺激小鼠产生大量的抗体和记忆细胞

ABCD

这得看语境,你光这么问我怎么知道用那种说法更通顺.
如果是,“20世纪70年代的那些人”,一般直接说 the seventies
如果是,“在20世纪70年代的时候”,
若是口语就直接说“In nineteen seventies“,
书面的话,”In the seventh decade of last century"或者“In the seventh decade of twenty century,"只是一般没有这么说话的
其实最常见的直接说1970s就好了

可以这样翻译
