Teaching College English by Metacognitive Strategies

In an information society,the English knowledge in capacity for college students has gradually been improved and its range is alsoenlarged.If teachers overlook summing up the knowledge which the students have gained and improving their skills in English,it will behard for students to learn English well.In educational circles people often say"teaching method isn’t fixed ",but it is of the same view togive students some basic regularity,let students have enough abilities and make knowledge which the students have gained assimilate and sys-tematize etc.Facing medical college students’tasks are arduous and the students often seem at a loss.In English lessons,it is necessary forteachers to help students find out some basic laws,give students enough skills and methods,let students sum up and classify knowledge whichis scattered,disorderly,bit by bit and even fragmented.     

The Application of CALL in Higher Vocational College

In recent years,with the rapid development of the informational,the digital and audio-visual technology,multimedia technology and its application have also entered a new development era in people’s life,especially in the academic field.In China,Computer Assisted Language Learning(CALL) has a far-reaching influence on the reforming and modernization of the education,and has brought about a new revolution in foreign language teaching and learning.The study,by means of a self-designed questionnaire,conducted a survey of the application of CALL with 120 English majors and 30 English teachers in a certain higher vocational college which the author works in.The study hopes that,with the help of the technological advantages of CALL and the rich on-line information resources via computers,the students’ study could be carried out in a more effective and convenient way.The results of statistical analysis revealed that,the majority of the students and teachers hold a positive attitude toward CALL application in language teaching and learning,though they have reported some weaknesses of CALL.According to the analysis,the paper attempts to discuss the advantages and the disadvantages of multimedia technology in English teaching and suggests several proposals to better the use of CALL.     

Motive in Learning English

Many people,men and women,old and young,are now leaming English by different means.Different people have different motives,and they will get different results in leaming English.Motive is very important in leaming English.     

Problems in English Education in China

Learning a language is mainly aimed at communication.But how many students even the college students can express themselves smoothly and understand others clearly in an English-only environment? Maybe a few students can meet the standard.This means that many problems exist in English teaching in China.Having gone through many books and websites related to English education,I have found many problems,and I hope I can figure out some solutions.     

A Description of Oral Errors for English Speaking Learners in Technical Colleges

Technical college students often commit different oral errors in their English learning. The type of students’spoken English errors is analyzed in this paper and the common errors are classified into four groups: phonological errors, lexical errors, grammatical errors and pragmatic errors. The result shows that lexical errors and grammatical errors are more common for learners from technical colleges.     

How to Stimulate College Students' English Learning Motivation

Motivation to language learning is a complex set of variables including effort, desire to achieve goals, as well as attitudes toward the learning of the language. Individuals' motivation to second-language learning also includes their motivation orientations, interest in the second language, attitudes toward the second-language group, attitudes toward the second-language learning situations and second-language anxiety. Based on the basic theories and approaches, teaching activities are part of motivation in English classes. The teacher of language should have a good influence on students and develop students' keen interest in study in order to strengthen their intrinsic motivation, and set up some new goals for students to pursue and give the feedback to reinforce their inner drive and confidence. Thus, students will become major conductors, make full use of their potentials and enhance their study results.     

Effective College English Vocabulary Teaching

There are over two million modern English words, thus English becomes a language with the largest vocabulary in the world. Moreover, English vocabulary is constantly being renewed and enlarged with the development of the society and advancement of science and technology. So vocabulary development becomes language learners’ top priority. Unfortunately, learning English words by rote can’t guarantee that students will have a large vocabulary, let alone enable students to make practical use of the words they h...     

4 K high frequency pulse tube cryocooler used for terahertz space application

Terahertz(THz) frequency region, defined from0.1 to 10 THz, is an important frequency band for radio astronomy and atmospheric science. As NbN Superconductor-Insulator-Superconductor(SIS) mixers used for terahertz detection, which are studied by the Purple Mountain Observatory(PMO), Chinese Academy of Sciences(CAS), work at 8–10 K, and require condition of micro vibrations, its astronomical observation in aerospace is limited by suitable refrigeration method. 4 K high frequency pulse tube cryocooler developed by Key Laboratory of Space Energy Conversion Technologies(SECT), Technical Institute of Physics and Chemistry(TIPC), CAS, offers an opportunity for the application of SIS mixers. This article introduces the progress of the two-stage high frequency pulse tube cryocooler researched by TIPC. The cryocooler has reached a no load temperature of 4.5 K which is the lowest temperature for this kind of cryocooler reported so far. The successful coupling between the THz component and the high frequency pulse tube cryocooler lays a solid foundation for space detection in the terahertz band.     

On the Functions of Euphemism in Social Communication

In the process of social linguistic communication, due to the different circumstances and conditions, people can not express certain things clearly in a direct way when they come across something painful, unpleasant, disgusted and even embarrassing. Instead, they have to use some vague, implicit, mild and euphemistic expressions, so as to achieve the purpose of expressing feelings and exchanging ideas and thoughts in an appropriate and light atmosphere. This paper tries to deal with the application of euphemisms in various fields, thereby reveal some main functions of euphemism, i.e. avoidance function, politeness function, gloss-over function and disguise function.     

Research and design of the main equipments and structure of Xiangjiaba shiplift

The type of pinion and rack vertical shiplifts has been developed in recent a couple of years in the construction of dams. But the design methods and methodologies have rarely been discussed in literature. The Xiangjiaba shiplift is the second shiplift of this type following the Three Gorges shiplift. Being aimed at the technological rationality of the design in synthetically considering security, economy and applicability, this paper presents the research results of some vital issues relating the design of the Xiangjiaba shiplift, including the determination of design water depth of ship chamber based on fluid numeral computation and physical model test, the optimum design of general layout of main equipments and the civil structure of the Xiangjiaba shiplift, the finite element method （FEM） analysis of stress, vibration modes and the buckling of ship chamber, antiseismic research and the design of structures and mechanisms of the shiplift and the optimum design of driving mechanisms. This research provides the theoretical basis for the design of the Xiangjiaba shiplift. The design principles and research methods are valuable for the design of the same type of shiplifts.     

Anomalous top-quark coupling effects in rare B and K decays

The Large Hadron Collider at CERN is performing direct searches for top-quark anomalous flavor-changing neutral current （FCNC） processes. However, these processes may be correlated closely with the low-energy rare B and K meson decays. In this paper, we review the anomalous top-quark coupling effects in these low-energy flavor transitions, summarize the flavor constraints and discuss their implications for direct detection of top-FCNC processes at the Large Hadron Collider.     

Distribution and origin of high magnetic anomalies at Luobusa Ophiolite in Southern Tibet

The Luobusa Ophiolite,Southern Tibet,lies in the eastern portion of Indus–Yarlung Zangbo suture zone that separates Eurasia from the Indian continent.An aeromagnetic reconnaissance survey has revealed an EWtrending Yarlung Zangbo River aeromagnetic anomaly zone,and it is considered to be caused mainly by the Indus–Yarlung Zangbo Ophiolite.The Luobusa Ophiolite reflects the eastern portion of the Yarlung Zangbo River aeromagnetic anomaly zone.Conventionally,the ultramafic rock in the Luobusa Ophiolite is considered as the origin of the high magnetic anomalies.However,results from the surface magnetic survey and the magnetic susceptibility measurements from drill cores indicate that the high magnetic anomalies are distributed inhomogeneously in the Luobusa Ophiolite.In some cases,the susceptibility exhibits more than 30 times difference between two sides of the same sample.A fact emerged that the susceptibility of dunite with serpentinization is higher than that of fresh dunite,harzburgite and chromite when we analyzed the measurement results.In order to understand the origin of the high magnetic anomalies,we measured the density and susceptibility of 17 samples,microscopic and electron probe analyses have been performed as well.The result indicates the presence of dunite with serpentinization containing an abundant of micro-fissures filled with magnetite.Olivine has a susceptibility of about 2.7–351(910-5SI),pyroxene about 16–320,and chromite about200–800.All these units feature relatively low susceptibility in ultramafic rock,and only the magnetite is characterized by a high susceptibility of about 200,000(910-5SI).Based on these observations,we conclude that the precipitation of magnetite in the process of serpentinization of the olivine caused by the geological process in the Luobusa Ophiolite is the origin of high magnetic anomalies.     

Observations of thermospheric vector wind over Yellow River Station during auroral substorm events

Strong disturbances associated with auroral substorms originate from the ionosphere-magnetosphere owing to the effects of the solar wind, and the wind field in the ionosphere is related to such substorm activity. Here, we describe the analysis of four auroral substorm events, for which we employed an all-sky Fabry-Perot interferometer to observe the two-dimensional horizontal wind field and combined the results with data from an all-sky charge-coupled device imager, a fluxgate magnetometer installed at Yellow River Station, and the Super Dual Auroral Radar Network. The results demonstrate that, during auroral substorms, the vector wind field is related closely to variations in the ion drift and geomagnetic field. Moreover, we observed a changing wind field of approximately 300 rn/s in response to variations in the electric and magnetic fields （likely caused by ion drag） and a disturbance of about 200 m/s that we attribute to the interaction of Joule heating and ion drag.

Phytolith carbon sequestration in bamboos of different ecotypes: a case study in China

Occlusion of carbon （C） within phytoliths （PhytOC） is becoming one of the most promising terrestrial C sequestration mechanisms. This study explored the production of PhytOC within 35 bamboo species belonging to three ecotypes using methods of microwave digestion. The aim of this study is to explore the present and potential C sequestration rate within phytoliths of bamboo species from three ecotypes. PhytOC content in bamboos of three ecotypes ranges from 0.07 % to 0.42 %. The mean PhytOC production flux decreases as： clustered bamboo （0.050 ± 0.016 t CO2 ha^-1 a^-1） ≈ mixed bamboo （0.049 ± 0.016 t CO2 ha^-1 a^-l） 〉 scattered bamboo （0.038 ± 0.020 t CO2 ha^-1 a^-1）. The phytolith carbon sequestration in Chinese bamboo is estimated to be 0.293±0.127 Tg （1 Tg = 1012 g） CO2 a^-1; approximately 75 %, 3 %, and 22 % of which is contributed from scattered, mixed and clustered bamboo, respectively. Taking the PhytOC production flux of 0.18 ± 0.12 t CO2 ha^-1 a^-1 and current annual area increasing rate of 3 %, global bamboo phytoliths would sequester 11.9 ± 7.9 Tg CO2 a^-1 by 2050. Consequently, bamboo forests have significant potential to mitigate the increasing concentration of atmospheric CO2 by maximizing PhytOC production flux and expanding bamboos.     

On the Translation of Individualism

In China,individualism is translated into ＂个人主义＂,whereas in western culture,the connotation of individualism doesn＇t equal to ＂个人主义＂ in China.Individualism is the soul of western culture which consists of the core part of western civilization,however,when interpreted into Chinese,individualism represents selfish.It is obvious that individualism is turned from positive into negative.The paper attempts at the proper translation and proves into the equivalence theory to find the reason.     

ZnO nanofluids – A potential antibacterial agent

In this work, ZnO nanofluids were produced by a medium mill with a pH value of about 7.2 and characterized by Nano-Sizer and SEM. After milling, ZnO nanofluids were formed with an average particle size of -198.4 nm. The ZnO nanofluids used for testing were stored for different periods （ 1 -, 90- and 120-day） and kept in different conditions （under the light and in the dark）. The antibacterial activities of these ZnO nanofluids were evaluated by estimating the reduction ratio of the bacteria treated with ZnO. The results showed that the ZnO nanofluid stored for 120 days under the light had the best antibacterial behavior against Escherichia coli DH5α. SEM images suggest that an interaction between the ZnO particles and the E. coli bacteria cells caused by electrostatic forces might be a mechanism.
