Directed by Employment--Embody the Feature of Higher Vocational English Teaching

With the rapid development of economic globalization,the communication in the field of economy,technology and culture has become more frequent between China and the international market.When companies and enterprises hire employees,they expect the graduates can both acquire professional skills and fluent English communication ability.In other words,they need elites who have higher quality and who can use English to communicate,negotiate and cooperate with foreigners in their professional fields.The central task of vocational colleges is to offer education for employment in the new era.So English teachers in vocational colleges face a more realistic problem,that is,how to make English teaching facilitate students’mastery of professional knowledge and adapt to the era’s development.     

A STUDY ON THE THEORY AND METHOD OF URBAN LAND EVALUATION GEOLOGY-ECONOMY

Over Long time,the coordination between land use and geological environments is neglected in urban construction.As a result,a huge sum of loss raised from the problems of geological environments occurs in many city. Because the influence of geological environments is neglected in pricing land,the price of urban land is not reasonable, which has influenced developing of land resource.The reasons resulting in above-mentioned problems are as follows;(1)the limitation of the geoiogical environments to land use is ignored;(2)the professional knowledge on the information of geological environments is a barrier for the planning and management of urban land to use;(3)it has not been resolved theoretically and practically how the information of geological environments can be transformed into the economic information which can be made easy to use of by the personnel in nongeologic fields. The approaches to solve the problems are that great attention must be paid not only to the limitation and influence of geologic

NEW DEVELOPMENTS IN REGIONAL STREAM SEDIMENTGEOCHEMICAL SURVEY FOR PLATINUM-GROUP ELEMENT

Over the past several years a multidiseipljnary study of the geochemical exploration of the platinum group elements (PGE) has been under way at the China.The new geochemical exploration techniques "using Pt,Pd metUometry to search PGE ores" was developed.The platinum and Palladium were taken as the direct pathfinder elements in this survey. As the PGE generally are present at low levels in the geochemical exploration samples,development work on analytical techniques was an essential part of this study. The Pr,Pd and Au elements in geochemical samples are dissolved by HCI-H_2O_2 using wet method, then adding SnCl_2 to the solution,the complex ions of Pt,Pd and Au will be formed.In the acid medium, these complex ions of Pt,Pd and Au can be adsorbed by activated charcoal.Their recovery rate has reached more than 95％. The ash content rate of the processed activated charcoal was very low. After separate and concentration,Pt, Pd and Au in 10g sample is only 0.3rug ashing,so the ratio of concentration is ove

GENETIC MINERALOGY AND METALLOGENiC PROSPECTIVE PROGNOSITC OF XIAYINGFANG GOLD—POLYMETALLIC ORE DEPOSIT,CHINA

The Xiayingfang gold-po|ymetallic ore deposit is located in the northeast edge of the Longxumen Mesozoic fault basin in the northern margin of the North China platform.The Archean plagioclase-hornblende gneiss, proterozoic sedimentary rocks and Mesozoic volcanic-sedimentaryrocks widely spread over the area.The gold-polymetallic mineralization is generally related to Xiayingfang granitoid body that consists of early formed diorite-porphyrite,granite-porphyry,with copper mineralization and last formed rhyoporhyry. The rhyoporphyry has the close relationship to crypto-explosive breccia and to gold mineralization in time and genesis. The quartz-sericitization is the main alteration and is closely related to the gold mineralization. The K-feldsparation develops at early periods and occurs inside quartz-sericitization zone. The prominent ore mineral is merely pyrite, the secondary are chalcopyrite, galena, sphelarite, clinoedrite, magnetite, as well as native gold, and the minor minerals are molybdenite, natur     

Stretching of Word Meaning in Semantic Changes

Part Ⅰ Language faithfully reflects the spirit of the age. As soiecity develops,new ideas are being conceived.and expressed by the people. Language, asthe carrier for the eagerest people who communicate, with each other, is toexpress new ideas, new processes, and new products. To meet the needs, alanguage can do three things:to form a new word, to borrow a word fromother languages, or add new meanings to established words. Of the threeways, the simplest one is to have old words taken in additional mean-ing. When a word losses its old meaning and comes to refer to something     

FROM GEOLOGICAL MOVEMENT TO GLOBE''''S MOVEMENT

The geological movement(1959) summarized the form of expression of thebasic contradictions in geoscientific objects of study, and it point out that one movement should in dependent the several other movements. Mr.considered, at a meeting on the problems of scientific philosophy in 1959,that the Geological Movement expressed the existing modeof inorganic Substances or mineral substances in individual celestial body. He said, further more,that the Geological Movement was the synthesis of several kind of movements, which is mechanistic movement, physical movement, chemical movement and biological movement.The Geological Movement was the result of considering the modern objects of geology and it showed the new developing achievements of geoscientific philosophy in this first century.     

On Differences between Chinese and Western Dietary Cultures From Ang Lee’s Work Eat Drink Man Woman

Diet is one of the necessities in our life, and even in the existence or development. Because of the differences between Chinese and western geographies, cultures, climate features, and ideologies, Chinese and western dietary cultures are totally different. This paper tries to explain the differences between Chinese and the western dietary cultures from the aspects of dietary forms and dietary concepts on the basis of Ang Lee’s work Eat Drink Man Woman, in order to show the dietary culture’s contrast and clashes under two different backgrounds.     

ON WUDANG GEOLOGY IN THE SOUTHERN QINLING OROGEN,NW HUBEI,CHINA

Wudang area is located in south part of the east segment of the gigantic latitudinal Kunlun-Qinling Tectonic System, which is called southern Qinling Orogen tectonically, between the N.China(or Sino-Korea) paraplatform and S. China (or Yangtze) paraplatform. The pre ponderating rocks in this area, mcta-sediments, recta-volcanic or volcanoclastic rocks, were once namedas"Wudang Schists"( Li Jie ＆ Zhu Sen, 1930) and called "the Wudang Group" lately. Since 1960s, the definition of the Wudang Group has been accepted gradually, but the intergroup sequence has not been adopted unanimously. The argument on the Wudang geology concentrates on rock sequence of the Group and tectonic frame, which is whether the sediments overlay the volcanic rocks or the later is up, and shows whether an antielinorium frame or monoclinic frame.In this paper, therefore, we are trying to reveal some key problems which show the Wudang Geology and tectonic evolution history.

A STUDY ON ECONOMY EVALUATION ON THE PROFIT AND LOSS OF GEOLOGIC ENVIRONMENTAL QUALITY ABOUT GEOLOGIC ENVIRONMENTAL EXPLOITATION PROJECT

The problems of environmental geology refer to the geologic phenomena, incidents or accidents arising from action of environmental geology. The action is mainly the mutual influence between human activity and geologic environment. When human activity is uncoordinated with objective laws of the geologic environment, the problems of environmental geology or economic loss would occur.Therefore,the level and the changing orientation of geologic environmental quality are relative to the types of human activity,particularly relative to human intentional-activities of geologic environmental exploitation project. The geologic environment fitting to mining may not fit to urban construction,and fitting to water conservancy and hydroelectric projects may not fit to communication,and so on.Economy evaluation on the profit and loss of geologic environmental quality is exactly to depict the level of the profit and loss of geologic environmental quality about geologic environmental exploitation projects and the feasibi

THE COMPOSITION AND TREND ANALYSIS OF DISPLACEMENTS FOR SPACE AND TIME ON THE LARGE-SCALE LANDSLIDES

The long-term quantitative monitoring for slope displacements is one of the important means of the middle-term or short-term forecast for landslide and the analysis on the sliding properties.Because of the differences of slope's boundary condition and the changes of many affecting factors such as the physical dynamic properties of slope-body,the stress field in it,ect,the monitoring displacement values of a slope are generally composed of creep deformation, compressive deformation and whole sliding deformation.The first and second displacements,which belong to local deformation,reflect the acting by the local stress,and the third displacement,which results from the acting of slope's overall stress field, represents the overall-trend displacement.Therefore, it is very significant that the whole-trend displacement is analyzed and judged correctly and systematically to the slope's stability evaluation and the forecast for landslide. This paper, using the long-term monitoring data of displacement of Xintan s     

GEOCHEMISTRY ON GENESIS OF XIAYINGFANG GRANITE—PORPHYRY IN NORTHEASTERN HEBEI,CHINA

Xiayingfang rock body occurs in Xinglong-Kuancheng arcuate folded area of Yanshan platform fold zone of eastern Yinshan-Yanshan east-west tectonic zone and is a small Yanshan-period composite stock that outcrops about 0.65 km~2. This permissive rock-body is closely controlled by the hinge belt of a regional asymmetric fold.The magma uptruded along the decollement plane between the layers and was eventually located in the pitching end of the fold due to the effect of the EW and NNE faults. The pitching direction of the stock is consistent with that of the anticlinal hinge, that is, it pitches towards SWW with 600--83~ plunging angle. Its wallrock strata includes Archaeozoic, Middle Proterozoic and Mesozoic erathems. The major rocktypes are adamellite-porphyry, moyrite-porphyry and alkali-feldspar granite-porphyry as well as rhyolite-porphyry and crypoexplosive breccia. Potassium feldspar is of higher order degree and fall into microcline-orthoclase series; plagioclase An=25-35; biotite is magnesian; acces
