基于语料库的中英报刊新闻标题语言特征研究

使用语料库方法从词汇和句法两个层面对比分析中英报刊新闻标题的语言特征,结果发现,尽管中英报刊新闻标题语言特征在总体上是相似的,但在具体的语言使用上仍存在许多差异。中国报刊英语新闻标题中大量出现的本土化词汇,在一定程度上反映了中国新闻英语的本土化倾向。     

基于3～6岁儿童生理特点的童装结构设计

3～6岁儿童正处于幼儿阶段,也是生长发育的关键时期.这一时期,儿童表现出活泼好动、行走稳健以及跑跳相对稳健的特点.因此,在这一时期的童装设计过程中,应充分考虑儿童的生长发育情况,生产出来的服装要具有穿着舒适性,有利于儿童的生长发育,更受家长的欢迎.     

基于语料库的广告英语语言特色分析

基于自建广告英语语料库,采用语料库统计方法分析了广告英语在词汇、句法和修辞等方面的语言特色。分析结果表明广告英语语句简单直接,采用大量褒义形容词、创新生造词和错拼词,并结合多种修辞手法,提升了广告本身的推销能力。     

基于益智功能的3~6岁儿童针织服装研究

介绍了3~6岁儿童的服装在身体发育、增长知识、培养想象力以及发展思维能力方面的益智功能。针对3~6岁儿童在色彩、图形、图案、附加物装饰4个方面的偏好进行试验,尝试性地提出了基于益智的3~6岁儿童针织服装设计的观点,并对3~6岁儿童益智针织服装的设计要素进行分析。结果表明:鲜艳自然的颜色,比较复杂且有玩赏性和熟悉感的图案,简洁大方的附加物装饰设计更有利于3~6岁儿童健康聪明地成长。     

基于语料库的服装英语语言特征及汉译研究

为了实现服装用语准确翻译,促进服饰文化传播,建立服装英语单语语料库,选取通用英语语料库作为参照,从词汇和句法两个方面对服装英语文本特征进行分析。发现服装英语文本用词丰富,存在一定量纯科技词汇和半科技词汇,名词化结构多,被动句和长句多。根据文本特征,探究其汉译策略,得出如下结论：从词汇来看,翻译纯科技词汇,需参照标准译文;对于半科技词汇,合理引申,查找求证;名词化结构可译成动词或四字格。从句法来看,对于被动句,可采用以下4种译法：变换主语、译成无主语句、增加逻辑主语以及使用“由、给、受、让、得以、加以”等词表达被动意义。对于长句的翻译,主要原则是打破关系找顺序,主要策略是分离重组。     

3～6岁儿童上体体型数据分析

近年来人们生活水平显著提高,儿童生长发育较早,当今儿童体型与以前的同龄儿童体型相比发生了明显变化。儿童体型的变化影响童装的设计生产。以石家庄地区3～6岁学龄前儿童为研究对象,采用接触式的测量方法获取大量与服装有关的部位的体型数据,并运用数理统计软件对数据进行分析,分析当今儿童体型特征,并与国标进行比较。     

3-6岁儿童体能训练的思考

3-6岁是儿童进入小学学习的关键时期,也是儿童体能发展的基础时期。有研究证明我国儿童体质呈现下降趋势,具有"软-肌肉软,力量差;硬-韧带硬,柔韧性差;笨-动作笨,灵敏能力差;晕-前庭耳蜗神经晕,平衡差"等特点[1],针对这些特点,本文对3-6岁儿童体能训练进行了思考。希望能对儿童体能训练计划的制定提供帮助。研究结果表明:在进行儿童体能训练时,应重视儿童生理和心理特点,重视核心肌肉群的训练,应以核心力量稳定性训练为主;重视柔韧训练;重视平衡觉的训练,应以翻滚类动作为主;重视灵敏训练。     

3-6岁儿童的合理营养

一、3-6岁儿童的生理特点3-6岁儿童身长和体重的增长相对来说比婴儿时期减慢,但四肢的增长比例却加快,体形逐渐变得细长(6岁儿童的腿长可占身长的44.6%),2岁以后的幼儿平均每年约增体重1-2公斤。学龄前儿童骨骼的化学成分与成人相比,骨胶多,钙盐少,因而骨的弹性大,硬度小,受压时,易弯曲变形,钙是构成骨骼的主要成分,需要充足供应,3-6岁幼儿处于长牙及换牙时期,乳儿从6个月开始出牙,20个乳牙最晚到2-3岁时出齐。6-7岁左右萌出恒牙,虽然最初的一个恒牙在6岁左右开始长出,但它的钙化过程却早在出牙前已经开始,因此及早地注意补充钙质和维生素D是非常重要的。学龄前儿童胃肠消化功能尚未发育完善,如胃的蠕动能力较弱,胃腺数目较少,胃腺分泌的消化酸度低,消化酶的含量比成人少,消化食物的能力较弱,应     

Challenges to the peer influence paradigm: results for 12-13 year olds from six European countries from the European Smoking Prevention Framework Approach study

Objective

To examine whether smoking onset in young adolescents is predicted by peer or parental smoking.

Design

Longitudinal design with one pretest and one follow‐up at 12 months.

Setting

Schools in Finland, Denmark, the Netherlands, the United Kingdom, Spain and Portugal.

Participants

7102 randomly selected adolescents from six countries. Mean age was 12.78 years.

Main outcome measures

Smoking behaviour of adolescents, peers and parents.

Results

No support was found for peer smoking as an important predictor of smoking onset in most countries. Support was found for the selection paradigm, implying that adolescents choose friends with similar smoking behaviour. Support for the impact of parents on adolescent behaviour and the choice of friends was also found.

Conclusions

Smoking uptake in this age cohort may be more strongly influenced by personal and parental influences than initially believed. Hence, social inoculation programmes teaching youngsters to resist the pressures to smoke may be less appropriate if youngsters have a positive attitude towards smoking, associate smoking with various advantages and look for peers with similar values. For this group attitudes towards smoking may thus guide future friend selection.

Sensory panel consistency during development of a vocabulary for warmed-over flavour

A sensory vocabulary of 20 terms each with a corresponding reference material was developed over 7 sessions using pork patties derived from the meat of carriers and non-carriers of the RN⁻ gene. Patties were oven-cooked at 150 and 170°C and chill-stored for up to 5 days to facilitate warmed-over flavour development. Generalised Procrustes Analysis (GPA) was used to investigate sensory terms and their individual use by panellists over the sessions. GPA explained variance indicated that the final vocabulary displayed a similar amount of information to that of the initial vocabulary of 42 terms. Individual panellists scale use was found to converge over the sessions. Panel agreement on many odour and flavour terms appeared to be enhanced as term synonyms were removed in vocabulary development. Sample discriminability decreased from sessions 1–4, where term concepts were verbally communicated to the panel. Term reference introduction in session 5 caused a levelling in sample discriminability and a reduction in agreement, most likely related to perceptual confusion. Subsequently, references enhanced both discriminability and agreement. Thus, it may be more useful to introduce reference materials earlier, if not in the first session, of the vocabulary development process.
