This study was carried out to investigate the influence of topic type on the quality of topic sentence. The participants, 150 college students at three different proficiency levels, were asked to write both on a private topic and a public topic. The results show that the participants on the whole wrote better on the public topic, and their proficiencies can be differentiated by the quality of their topic sentences. The public topic was conducive to the production of complete English discourse structures, as well as the generation of informative and predictive topic sentences. Moreover, the results also reveal the dynamic nature of contrastive rhetoric展开更多

The dynamics of growth and thickening of the cultivars Independence, Nectagrand 2, Aureliogrand, Fantasy, Kassiopeia and Caldessi 2000 grafted on seedling rootstock （Elbert） and clonal GF-677 have been studied in the second year of nursery. The aim of the study was to investigate the growth characteristics of the introduced cultivars of nectarines grafted on traditional seedling rootstock （Elbert） and GF-677. At the beginning of the vegetation period of the seed cultivar rootstock （Elbert） has strong growth and thickening of the stem. The dynamics of growth and thickening of the stem depend on the used rootstock and cultivar. The obtained planting material corresponds to the existing quality standards.展开更多
