This study aims to provide guidance on the syntactic features that L2 learners can employ, as well as suggest which features they should focus on in English academic writing. To achieve this, all samples were analyzed for rhetorical moves using Hyland’s five-rhetorical move model. Additionally, all sentences were evaluated for syntactic complexity, considering measures such as global, clausal and phrasal complexity. The findings reveal that expert writers exhibit a more balanced use of syntactic complexity across moves, effectively fulfilling the rhetorical objectives of abstracts. On the other hand, MA students tend to rely excessively on embedded structures and dependent clauses in an attempt to increase complexity. The implications of these findings for academic writing research, pedagogy, and assessment are thoroughly discussed.展开更多

In the 1990s runoff of Tangnaihai Hydrologic Station of the Huanghe River experienced a serious decrease, which had attracted considerable attention. Climate changes have important impact on the water resources availability. From the view of water cycling, runoff coefficients are important indexes of water resources in a particular catchment. Kalinin baseflow separation technique was improved based on the characteristics of precipitation and streamflow. After the separation of runoff coefficient (R/P), baseflow coefficient (Br/P) and direct runoff coefficient (Dr/P) were estimated. Statistic analyses were applied to assessing the impact of precipitation and temperature on runoff coefficients (including Dr/P, Br/P and R/P). The results show that in the source regions of the Huanghe River, mean annual baseflow coefficient was higher than mean annual direct runoff coefficient. Annual runoff coefficients were in direct proportion to annual precipitation and in inverse proportion to annual mean temperature. The decrease of runoff coefficients in the 1990s was closely related to the decrease in precipitation and increase in temperature in the same period. Over different sub-basins of the source regions of the Huanghe River, runoff coefficients responded differently to precipitation and temperature. In the area above Jimai Hydrologic Station where annual mean temperature is -3.9℃, temperature is the main factor influencing the runoff coefficients. Runoff coefficients were in inverse relation to temperature, and precipitation had nearly no impact on runoff coefficients. In subbasin between Jimai and Maqu Hydrologic Station Dr/P was mainly affected by precipitation while R/P and Br/P were both significantly influenced by precipitation and temperature. In the area between Maqu and Tangnaihai hydrologic stations all the three runoff coefficients increased with the rising of annual precipitation, while direct runoff coefficient was inversely proportional to temperature. In the source regions of the Huanghe River with the increase of average annual temperature, the impacts of temperature on runoff coefficients become insignificant.展开更多

It is very popular because of the big size, bright color, various shape, and long period of bloom. New species should be cultivated in order to meet the consumers' need of asking for the new. Among the technologies of cultivating new species of flowers, mutagenic breeding is a shortcut. This study treated corm bud of G. hybridus Hort with EMS of different consistency. Then M1 after treated was analyzed by RAPD. The result showed that EMS was a very effective mutagenic agent for the corm bud of G. hybridus Hort. With the increase of consistency, the mutagenic range increased first, then decreased, among which 0.6% EMS treatment had the biggest influence. However, with the same EMS consistency, there was not close relevancy between the amount of mutagenic agent and the divergence of plant's genomes, which offered a molecular basis for selecting plants with good mutation.展开更多

Based on Rogers' learner-centered humanistic teaching approach which emphasizes students' involvement and experiences in learning, EFMH puts students and their practice in a central place. After four-year exploration and operation, the Forum has developed from a small-scaled embryo into an internationalized, standardized and professionalized event, having produced fruitful outcomes. It is expected that the success of EFMH will provide inspiring experiences and enlightenments for higher medical education in terms of academic English teaching and teachers' responsibilities to foster high-quality medical students.展开更多

Methods: Prospective nonrandomized controlled trial was used. A total of 105 patients(210 eyes) were divided into three groups according to the type of IOLs: ZA9003(35 patients, 70 eyes), MCX11 ASP(35 patients, 70 eyes) or HQ-201HEP(35 patients, 70 eyes). The main outcome was scores of Catquest nine-item short-form questionnaire. Additional outcome was best corrected visual acuities, spherical aberration(SA) and total higher-order aberrations(HOAs). Results: The global score was significantly lower in the spherical IOL group than the aspherical IOL group of-020 μm SA(P < 0.05) and the aspherical IOL group of-027 μm SA(P < 0.05), and no significant difference was found in the global score between the aspherical IOL group of-020 μm SA than the aspherical IOL group of-027 μm SA(P > 0.05). Significant differences were also found in question 2, question 5, question 6 and question 8 between the spherical IOLs and the aspherical IOLs. Conclusion: Implantation of an aspherical IOL could improve vision-related quality of life compared with a spherical IOL. However, there were no statistically significant differences in vision-related quality of life between aspheric IOLs with different negative spherical aberrations.展开更多

The permittivity, resonant frequency and dielectric loss of the composites have been measured under vertical stress and temperature, and the variety of the material properties under pressure and temperature could also be obtained. The pressure and temperature stability of the composites have been assessed through experiments. The data of these two types of composites indicated that the stability of 1-342 composite with pressure was better than that of 1-3 composite, and two composites have almost the same dielectric stability with temperature. However, 1-3-2 composite showed slower frequency variation than 1-3 composite.展开更多

She writes like a social realist, but when she is confronted with taking a position, she often opts for reconciliation or even escapism. Gaskell's ambivalent attitude towards social classes is brought to the forefront in Mary Barton (1847), which she originally entitled John Barton. The change of the title has led to critical argument that the novel is an artistic failure, and the shift from a political novel with a clear social purpose to a domestic romance which covers up social discontent is too unprepared and comes across as a fantasy on the part of the novelist. This peculiar structure of the novel reveals the limitation of Gaskell's social vision as a novelist. In North and South (1852), Gaskell presents the precarious situation of workers and their tense relations with industrialists in a more balanced way by giving more attention to the thinking and perspective of the employers, a narrative perspective far different from her treatment in Mary Barton which adopts the view of the working poor. The on-going social mobility and the shift of social gravity from the aristocracy to the mercantile, a historical reality which Matthew Arnold clearly delineates in Culture and Anarchy, are truthfully observed and represented by Gaskell and her representation of this new ruler class marks her progressive social view, expressing her optimistic belief in England's progress towards an industrial future. In an interval of seven years between the publications of the two novels in question, Gaskell's social vision had matured into critical realism.展开更多

The participants in this study were 32 intermediate senior students of Shiraz Azad University majoring in English translation. The Word Associates Test (WAT) (Read, 1993) was used to measure their depth of vocabulary knowledge and lexical inferencing strategy questionnaire which was part of Schmitt (1997), vocabulary learning strategies as well as a reading passage (Haastrup, 1999), cited in Nassaji (2004), were used to determine their lexical inferencing strategy use and success. Results indicate that: (1) Those who have stronger depth of vocabulary knowledge use certain strategies more frequently than those who have weaker depth of vocabulary knowledge; (2) The students with stronger depth of vocabulary knowledge make more effective use of certain types of lexical inferencing strategies. These findings support the importance of depth dimension of vocabulary knowledge and the role it plays in guessing the meaning of unknown words.展开更多
