Over 300 sample texts produced by intermediate learners were collected from a test and some regular after-class assignments for English writing courses. Each participant completed two writing tasks, one argumentative and the other narrative. Results show that genre type has a significant impact on L2 syntactic complexity. Genre effect is found stronger with timed writing tasks. L2 holistic ratings show correlation with syntactic complexity on the different measure(s) depending on genre type and planning conditions. Regression analyses reveal that for timed writing tasks, clausal density(clauses per sentence) is a reliable predictor for holistic assessment on intermediate EFL learners’ writing quality. It is found to account for 6% of the score variance for timed writing and 10% for timed argumentative writing. Genre is evidenced to be related to EFL writing holistic ratings. Closer examination indicates that while syntactic complexity is predictive of holistic writing scores for argumentative writing, it does not correlate with holistic scores for narrative writing. Other linguistic features rather than syntactic complexity may be accountable. Overall, the study lends support to genre effect in the relationship between syntactic complexity and L2 writing quality holistic rating.展开更多

He excelled in this era with his trend of magic realism. The Shadow Lines is a story told by a nameless narrator in recollection. It＇s a non linear tale told as if putting together the pieces of a jigsaw puzzle in the memory of the narrator. This style of writing is both unique and captivating; unfolding ideas together as time and space coalesce and helping the narrator understand his past better. Revolving around the theme of nationalism in an increasingly globalized world, Ghosh questions the real meaning of political freedom and the borders which virtually seem to both establish and separate. The novel traverses through almost seventy years through the memories of people, which the narrator recollects and narrates, giving their viewpoint along with his own. Though the novel is based largely in Kolkata, Dhaka, and London, it seems to echo the sentiments of whole Southeast Asia, with lucid overtones of Independence and the pangs of Partition.展开更多

In fact, he was one of the most important figures who created a few of theories and also were good at film creation in the film history of over years. He was not only an outstanding master-level film director, but also film theorist who created rich thoughts to the world. He often discussed the film theories with intercommnnity by taking his own works such as Bronenosets Potyomkin for an example, and simultaneously connected paintings （especially the Oriental painting）, music, literature and others with new arts in the writing of theories, so that the construction of his own film theories was accomplished. The focus of this paper is the later consideration of Sergei Eisenstein on the film works structure. Also, his theoretical system and contemporary significance are rethought by studying a series of thoughts such as ＂works structure＂ , ＂dynamic characteristics＂ , ＂logarithmic spiral＂ , ＂golden section＂ and ＂passionate structure＂ .展开更多

The effects of seven factors, which are substrate temperature, sputtering atmosphere, working pressure, sputtering power, annealing temperature, negative bias voltage and sputtering time, on Hall mobility, transmittance and surface roughness are studied through orthogonal experiments. The results show that the effects of working pressure, substrate temperature and sputtering atmosphere on performance of films are the most prominent. According to the experimental results and discussion, relatively reasonable process parameters are obtained, which are working pressure of 0.35 Pa, substrate temperature of 200 ℃, sputtering atmosphere of Ar, sputtering power of 125 W, sputtering time of 30 min, negative bias voltage of 0 V and annealing temperature of 300 ℃.展开更多
