Palaeogeography is a branch of geosciences, which studies natural geographical features in the geological history. The research targets are the evolution history of oceans and continents, and the distribution and characteristics of the internal palaeogeographic units.

古地理学是研究地质历史时期自然地理特征的地质科学，其研究目标是海洋和陆地的变迁历史及其内部古地理单元的分布和特征。

Palaeogeography is a science which studies natural geographical features in the geological history and humankind history. It is of important theoretical and practical significance, and closely related with past and present geographical environments in which humankind lives.

古地理是研究地质历史时期和人类历史时期的自然地理特征的科学，有重要的地学理论意义和生产实践意义，还与人类赖以生存的古今地理坏境密切相关。

Geological archives in geological exploration organizations are the realest records of geological work history and are very precious historical material which objectively reflect geological work in various historical periods.

地勘单位的档案资源是地质工作历史的最真实的记录和珍贵的历史资料。它客观地反映了各个历史时期地质工作状况。

The south-north united tectonic environment and tectonic pattern does not exist. The east-west trend thrusting Nappe structure of Majiatan and Hengshanpu can not represent the whole western margin of Ordos. The attempt to solve the regional tectonic problem with simple tectonic pattern is against the geological theory, especially in the Helan Mountain region.(2) After the geochemical data analysis of Ruqigou basalt in Helan Mountain, the article illustrates that it belongs to continental rift basalt which appeared in the late-Triassic and early middle Jurassic. Meanwhile the article states that the region is located in the rift environment of an extension background and Rudigou is located in the central part of the rift.(3) The article illustrates that the western ridge of Helan Mountain used to be on a slope and topography slowly declines from west to east after analysis and demonstrations of the distribution under XiaoSongshan bedding fault. Through comprehensive analysis of the no-strong deformation and bedding fault features, the article states that the Xiaosongshan bedding fault used to be gravity slip detachment structure and it represents the extension from the east to the west. Based on the above and analysis and demonstrations of isotope age and track datting, the article illustrates that the ? characteristic of the east of the western ridge of Helan mountain being higher than the west is the result of its late tectonic reverse.(4) Through comparison between Rujigou region Mesozoic Era late Triassic period-early and middle Jurassic period deposit and that of Ordos Basin and the analysis of the late Triassic period extension and early -middle Jurassic Period deposit povenevance it sets forth that during the period, Rujigou region was part of a large deposit basin which was closer to the northern povenevance and farther from the western povenevance.

以马家滩和横山堡为代表的东西向逆冲推覆构造模式，在整个鄂尔多斯盆地西缘不具有全区统一性，那种试图用单一的构造模式解决本区构造问题的尝试，无疑是与地质实际相悖的，尤其是对贺兰山地区；(2)通过对贺兰山汝箕沟玄武岩地质地球化学测试分析，提出其为大陆裂谷玄武岩，其形成时代为晚三叠—早中侏罗世，并通过该玄武岩的稀土和微量元素的测试分析资料进行了多种判别分析，最终确定该区处于拉张背景下的裂谷环境，汝箕沟地区大致处于当时裂谷的中心部位；(3)通过对小松山断层面之下地层分布规律，结合其变形特征的分析论证，认为当时贺兰山西麓处于一个由东向西平缓抬高的斜坡环境，并通过小松山断层面之下地层的非强烈变形及顺层断层特征等的综合分析，认为贺兰山西麓的小松山断层原本是一重力滑覆断层，它代表了近东西向的拉张，在此基础上通过裂变径迹测试资料的分析论证对其做了进一步认定，目前贺兰山西麓东高西低的剖面特征是该区后期构造反转的结果；(4)通过对汝箕沟地区中生代晚三叠世—早中侏罗世沉积与鄂尔多斯盆地内部的对比、晚三叠世延长组及早中侏罗世沉积物源和水流向分析，认为该时期汝箕沟地区为一更靠近北部物源，而距西部物源明显较远的沉积环境，是一更大型沉积盆地的一部分。

Cave deposits a large number of clay-dong for the fish to add a big tourist attractions, very rare realistic, geological strange, stone flower, cloud basin, geese control, such as geological heritage landscape is the human nature has given the outstanding work, a strange male secluded insurance characterized include a variety of different periods of the cave sediments, has been spectacular.

洞底沉积大量泥土为鱼谷洞增添一大旅游特色，十分罕见逼真，地质奇特，石花、云盆、鹅管、地质遗迹等景观是大自然赋予人类的杰出作品，一雄险奇幽为特点，囊括了各种不同时期洞穴沉积物，令人叹为观止。

In the future period, the innovation and development of geologic work require more and more socialized service of geological samples, and on the other hand, the government and the public desiderate service of geo-science information.

今后时期，不仅地质工作的创新与发展，对实物地质资料社会化服务的需求程度越来越高，而且政府和公众也亟需地学信息服务。

Palaeontologists successfully obtained the essential information of palaeo-CO2 change form fossil plant leaves. This method has been recognized as one of the effective approaches for tracking paleo-CO2 information from geological record.

古生物学家通过对植物化石叶片的研究，成功地获取了地质历史时期古大气CO2浓度变化的信息，因而这一方法日益受到科学界的重视，被认为是从地质记录中获取古大气CO2浓度的最有效途径之一。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
