英语新闻的标题特点
新闻标题具有简洁、重点突出、语言新颖等特点.英语新闻标题主要运用省略、以符代字、头韵和尾韵、双关语等方法来实现这些要求.
1.省略的运用
在英语新闻的标题中,冠词、代词、be动词、名词所有格等不影响语句实际意思的词语通常被省略.例如,省略代词:China bans imports of DPRK raw minerals,aviation fuel exports (China bans its imports of DPRK raw minerals,aviation fuel exports) (Xinhua,2016-04-05)这里省略了代词“its”. 相似文献

批转、转发、印发性通知标题中的“关于”是可以省略的,因为“关于”不是公文标题所规定的三个组成部分之一.一般的公文标题之所以有“关于”,是为使语言表达符合语法规范,表达效果更好;批转、转发、印发性通知标题省略“关于”不违反语法规范,所以,为增强表达效果,在一定条件下应该是可以省略的.关于“关于”,当务之急不是应不应该省略,而是应该怎样省略的问题. 相似文献

科技语言中的省略 总被引：3，自引：2，他引：1
在科技文献中,常常可以见到各种各样的省略现象。例如,f(x)=x_1+…+x_k;将“微型电子计算机”称为“微机”等等。科技语言中的省略与文艺语言中的省略不同。在文艺语言中,省略主要作为一种修辞方式,而在科技语言中,省略则几乎是必不可少的表达手段。如果不使用省略,不仅文章繁琐,而且许多的情况及过程,如无限情况,无限过程无法表达;如果省略方法使用不当,则可能造成表达不清或出现歧义,因而对科技语言中的省略进行探讨,分清其类型,了解其规则,掌握其技巧具有现实意义。这一讨论既有助于科技语言表达规律的研究,又可为科技编辑审读文稿时提供一些检查方法,此外对于提高科技人员写作能力亦起积极作用。 相似文献

古今汉语都有省略现象,可是文言省略现象比现代文尤为突出,成为文言文的特色之一。句子某些词语的省略,从语法角度着眼,是有规律可寻的。能够掌握这种省略规律,遇到具体省略现象,将不至于感到迷惑。先看主语的省略。上句已出现主语,下语的主语便可省略,如“楚人为食,吴人及之;楚人奔,吴人食而从之”(《左传·定公四年》)中有(?)符号标明的主语“楚人”“吴人”就是承上文的“楚人”“吴人”而省。下句要出现主语,上句主语也可以省略,如“项王夜闻汉军四面皆楚歌,项王乃大惊曰:‘汉皆已得楚乎?是何楚人之多也!’”(《史记·项羽本纪》)中的上一句的“项王”就是蒙下一句的“项王”而省。还有,下一句的主语就是在上一句里充当宾语的那一个,这下一句的主语仍可以省略(这样更显得结构紧密),如“……触草木,草木皆死”(《捕蛇者说》)就 相似文献

Researchers theorize that modal expressions (e.g., can, may, could, and should) serve politeness functions in discourse, particularly in requests and refusals. This study sought to empirically determine whether requesters perceived refusals containing modal expressions as more polite than their non-modal counterparts. The results showed that refusals containing modal expressions are judged as more polite but they are mixed when examining whether refusals containing modal expressions are perceived as more effective than their non-modal counterparts. The discussion section addresses the implications of these findings for the study and creation of refusal messages. 相似文献

Matching Index Expressions for Information Retrieval 总被引：6，自引：0，他引：6
The INN system is a dynamic hypertext tool for searching and exploring the WWW. It uses a dynamically built ancillary layer to support easy interaction. This layer features the subexpressions of index expressions that are extracted from rendered documents. Currently, the INN system uses keyword based matching. The effectiveness of the INN system may be increased by using matching functions for index expressions. In the design of such functions, several constraints stemming from the INN must be taken into account. Important constraints are a limited response time and storage space, a focus on discriminating (different notions of) subexpressions for index expressions, and domain independency. With these contextual constraints in mind, several matching functions are designed and both theoretically and practically evaluated. 相似文献

Based on norm violation theory, we examined students' reactions to teachers' normative and nonnormative expressions of anger. College students ( N = 301 ) judged the appropriateness and intensity of teachers' anger in the classroom for four modes of expression: Distributive Aggression, Passive Aggression, Integrative Assertion, and Nonassertive Denial. Students rated both types of aggressive expressions as highly intense and inappropriate (or nonnormative), but assertive displays as appropriate and less intense. Additionally, aggressive expressions were negatively related to students' affect, whereas assertive expressions were positively related to affect. Findings extend norm violation theory by identifying how teacher anger should be expressed and when during the semester anger is more likely to be perceived as inappropriate. Moreover, this study illustrates how normative violations of anger are associated with negative evaluations of the teacher and course. 相似文献

Athletes’ expressions of dissent are largely unrecognized, which limits coaches’ abilities to manage their teams and athletes’ abilities to voice themselves effectively. This study considers athletes’ roles on their teams, sport type, and relationships with coaches and teammates as predictors of upward and lateral expressions of dissent. Results gathered from 273 former high school athletes revealed a complex pattern of social interaction, whereby starting status and relationships with teammates directly predicted upward dissent and athlete–coach relationships indirectly predicted upward dissent. In contrast, only athletes’ relationships with coaches predicted their expressions of lateral dissent. These findings suggest that in order to promote functional patterns of athlete dissent coaches must build quality relationships with athletes, as well as climates that facilitate cohesion among athletes. 相似文献
