And the Precambrian was a main period of the growth of the continental crust. Therefore the origin, formation and evolution of the continental crust and their model are some of the most important problems to which earth scientists pay close attention.

前寒武纪还是大陆地壳生长的主要时期，大陆地壳的形成、成因、演化过程及其模式是地球科学家最关心的问题之一。

The results of the study indicate:(1) the stress, strain and velocity fields as well as the uplift rates of the model are consistent essentially with those of the prototype in nature;(2) the major driving force for intraplate tectonic deformation in central-eastern Asia results mainly from the compression of the Indian plate;(3) the existence of the RSBs, such as those of Tarim, Alxa, Ordos and Sichuan basin, is one of the basic origins for the development of large-scale compressional basins and the table-like uplift of the Qinghai-Tibet plateau;(4) The netlike plastic-flow in the lower lithosphere is faster than the displacement in the upper layer, controlling the tectonic stress and deformation fields in the upper crust;(5) the weakness layer distributed discontinuously in the middle crust influences the level of difference between the stress directions in the lower lithosphere and those in the seismogenic layer.

研究结果表明：(1)模型中的应力场、应变场、位移速度场和地表隆升速率，与自然条件下的实际状况基本相符；(2)中东亚板内构造变形的驱动力源主要来自印度板块的推挤作用；(3)塔里木、阿拉善、鄂尔多斯、四川盆地等相对稳定块体的存在是促成大型压性盆地形成和青藏高原平台式隆升的基本原因之一；(4)岩石圈下层的网状塑性流动超前于上层，控制上层的构造应力场和变形场；(5)中部地壳的非连续分布软弱层影响上、下层之间应力方向的差异程度。

Summing up these results, we think that the Yinmawanshan batholith came from the mixing, the fractional crystallization and the crust contamination of the enriched lithospheric mantle and the low crust magma.3、the time relationship between the Yinmawanshan batholith' formation and the tectonic extension The field observation and petrology have clearly showed that the Yinmawanshan batholith intruded in the forming period of the Liaonan metamorphic core complex, so this provided direct geological evidence to the viewpoint that the early Cretaceous magamatism of the eastern China developed in the extensionally tectonic setting.

还有一个证据来自对A型花岗岩的研究。A型花岗岩的年代学研究结果显示在东北的大兴安岭地区、张广才岭地区、本文研究区的辽东半岛，几乎所有的上述A型花岗岩都是在120-130 Ma期间形成的，与本文研究的饮马湾山I型花岗岩同时。地球化学资料还显示，这些花岗岩基本具有A1型非造山花岗岩的特点，充分反映了我国东部早白垩世的地质演化与伸展体制有关。根据上述资料我们推测，辽东半岛南部饮马湾山岩体形成时的我国东部由于受岩石圈减薄作用影响而使全区处于伸展构造体制。

5In the mantle—the thick shell of rock that lies between Earth's crust and its metallic core.Althougmath the hot rock of the mantle is a solid, under the tre-mendous pressure of the crust and

在gmat阅读理解中，假如一道题目的正确答案是a而我们错误的选择了 b，我们总会听到这样一种声音给我们讲题：你在看看原文，其实b和原文不对应，你在看看原文那个地方其实a就和原文对应，只是因为你没读懂。。。

The relationship between mantle fluid and U ore-forming was studied preliminarily,according to the results,the author considered theΣCO_2 of mineralizer and heat source came from mantle,which is because upwelling mantle forced by crustal extention and deep-seated faulting produced melt blending with lower crust,during this process,mantle provided the heat and releaseΣCO_2 to crust through outgassing.U mainly came from mantle-curst fluid formed by mantle-curst melt blending and the wall rock during fluid uplift.H_2O mainly generated from mantle fluid and the wall rock during mantle fluid uplift,and partly from atmospheric water in the late period of ore-forming.

初步探讨了地幔流体与铀成矿作用的关系，认为矿化剂∑CO_2和热源来源于地幔，是地壳拉张和深大断裂活动导致部分熔融地幔上涌，与下地壳产生壳幔混熔作用，在混熔过程中提供热量和向地壳&去气&释放∑CO_2；U主要来源于壳幔混熔形成的壳幔混合流体和流体上升途经的围岩；H_2O主要来源于地幔流体、地幔流体上升途经的围岩，在成矿晚期有部分来源于大气降水。

To study the deep faults of crust through geophysics not only provides proofs to further study of basic theories such as the crust evolution and continent formation, but also provides an important guidance to classifying tectonic units, analysing and predicting natural earthquake activities and studying different kinds of mineralisation.

利用地球物理研究地壳的深部构造，不仅为地壳的演化和大陆的形成等基础理论问题的深入研究提供证据，而且对划分大地构造单元、分析和预报天然地震的活动性以及研究各种矿产的成矿规律也具有十分重要的指导意义。

Since the Dabie orogenic belt was affected meanwhile by the delamination of post collision of Indo-Chinese epoch and the subduction toward EuraAsia continent of Izanagi plate, the upwelling of asthenosphere material supplied a lot thermal energy for crust, isobathythem ascented, this made middle and lower crust amphibolite and granulite facies metamorphic and large-scale free water-bearing system and large area migmatites and granites were formed.

在大别造山带印支期碰撞后所产生的拆沉作用和伊佐奈崎板块向欧亚板块的NWW向俯冲作用的共同影响下，软流圈物质上涌，为地壳输送大量的热能，等温面上升，使中下地壳发生角闪岩相或麻粒岩相变质作用和大规模含自由水体系的熔融，形成了大面积混合岩和花岗岩。

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.

交际能力和语法的关系应该是目标与途径的关系。
