The application of conjunction can achieve cohesion. However, according to the definition of register and genre, it is hard to find the total or completed function of these conjunctions in press release. The reason why this kind of phenomenon comes cross should be discussed in this paper. For doing this research, the researcher chooses one discourse which was found at www. globaleducationfirst.com as the material and select the conjunction out to prove the function of connection in application. As a kind of research, the aim or target is more important because as all paper goes, the purpose should be concentrated on. Why a style like news broadcasting or press release has so little conjunction functions as, for example, addition, means and, or contradictive but, however, and yet, or condition/f and so on. Some of them functions as internal, but others external. Whether it is the deliberate consideration or free formation by the editor is finally should be discussed, and from this point of view, conjunction' s function in press release reaches the target of cohesion展开更多

We studied 36 cultivars or lines which had been preserved in Tea Germplasm Garden of Fujian. The contents of catechins in spring tea shoots, summer tea shoots and autumn tea shoots in 36 varieties and lines were analyzed by HPLC. Analysis of these tea varieties and lines revealed that the catechins contained in the tea shoots in different seasons are highly variable. The content of ester-catechins in spring and summer tea shoots was higher than that of autumn, while non-ester-catechins did not showed the same characteristic. The content of EGCG showed an extremely significant positive correlation with T1 (T1 = EGC + EGCG + GCG + EGC), an extremely significant negative correlation with DL-C, the content of EGC showed the same characteristic. Among them, 10 cultivars with less bitterness and astringency index (the annual average bitterness and astringency index 〈 8.0) were considered good candidates as important breeding materials tbr tea infusion quality improvement.展开更多
