欧盟将禁止一次性塑料制品

The European Commission is proposing a ban on around 10 single-use plastic items that it says account for approximately 70 percent of all garbage in the European Union's waters and beaches, including cutlery, straws, cotton buds, plates, some coffee cups, and stirrers.欧洲委员会近日起草了一份针对一次性塑料制品的禁令,包括塑料刀叉、吸管、棉签、餐盘、部分咖啡杯、搅拌棒等,而这些塑料据称占据了欧盟水域和沙滩漂浮垃圾中的7成。The legislation is not just about banning plastic products. It also wants to make plastic producers bear the cost of waste management and cleanup efforts, and it proposes that EU states must collect 90% of single-use plastic bottles by 2025 through new recycling programs.这项法令不仅仅是简单的“禁塑”,它还要求塑料厂商承担起塑料废物处理和清理的相关责任,法令还提议欧盟国家在2025年前通过新的垃圾循环计划,对90%的一次性塑料瓶进行回收再利用。The European Commission estimates that these rules, once fully implemented in 2030, could cost businesses over €3 billion per year. But they could also save consumers about €6.5 billion per year, create 30,000 jobs, and avoid €22 billion in environmental damage and cleanup costs. In all, the new legislation is beneficial for the economy in the long run.欧委会预计这一系列新法规将在2030年全面执行,可能造成企业每年30亿欧元的亏损。但与此同时,新法规每年能为消费者节约65亿欧元的支出,创造3万多个就业机会,减少220亿欧元的环保支出。所以总的来说,这项新法规在经济层面上是利大于弊的。Currently, the plastic reuse rate is frankly embarrassing compared to other products. While just 14 percent of all plastic used globally is collected for recycling, the rate for paper is 58 percent and the rate for iron and steel is around 90 percent. Scientists have concluded that the Great Pacific Garbage Patch, an area of the ocean where huge amounts of discarded plastic items eventually end up, has now grown to at least 87,000 tons of marine wildlife-killing waste.当前,塑料的再利用率比起其他材料要低得多。全世界只有14%的塑料得到了回收利用,而纸制品则达到了58%,钢铁的回收率更达到了90%。科学家目前得出结论,由洋流将海洋垃圾汇集在一起的“大太平洋垃圾带”,规模已经达到了惊人的8万7千吨以上,对海洋生物造成了严重的威胁。The ban doesn't mean that consumers in the EU will suddenly be unable to get these items; instead, products like plastic forks and knives with "readily available alternatives" would be replaced with products made from more environmentally friendly materials like bioplastics.这项禁令并不意味着欧盟的消费者会突然间买不到上述产品。相反,像塑料刀叉这种已经有“现成替代品”的产品将会被更多环境友好型的材料取代,例如可以轻松降解的生物塑料。"Europeans need to act together to tackle this problem," EU vice president Frans Timmermans said. "Today's proposals will reduce single use plastics on our supermarket shelves through a range of measures. We will ban some of these items, and substitute them with cleaner alternatives so people can still use their favourite products."欧盟委员会副主席Frans Timmermans说道,“欧洲需要携起手来共同应对塑料问题。今天的提议将通过一系列举措减少市场上流通的一次性塑料制品,我们在下达禁令的同时,也将用更加环保的材料进行替代,确保消费者能够继续使用他们喜爱的产品。”Vocabularycutlery: n. 刀叉stirrer: n. 搅拌器;搅拌棒bioplastic: n. 生物塑料

炎炎夏日中的冰爽美味

China has entered Toufu on July 17th, the first phase of Sanfu. In the Chinese lunar calendar, Sanfu refers to the hottest period of the year, which includes three phases, that is, Toufu, Zhongfu and Mofu. On the long, hot summer days, few people have a good appetite. Ice cream and fruit sound more refreshing than a bowl of hot noodles.7月17日我国正式进入“头伏”,也就是三伏天的第一阶段。在中国农历中,三伏天意味着一年中最热的一段日子,前中后分为“头伏”、“中伏”和“末伏”三个阶段。在漫长的炎炎夏日中,人们的胃口常常欠佳,这个时候,相比一碗热气腾腾的汤面,冰激凌和水果就显得更加诱人了。Ice cream may be deemed as western dessert: the classic creamy texture is quite different from Chinese tastes. Actually, Chinese people have enjoyed "ice cream" in summer since ancient time. Here are some icy delicacies on summer days in ancient China and currently popular ones.冰激凌在我们印象中总是显得很西式:经典细腻的口感和我们东方的口味显得相距甚远。但实际上,中国的古人很早就开始享用那时的“冰激凌”了,接下来我们就来看一下古时和现在的一些夏日冰爽佳品。Icy Delicacy Favored by Royals and Nobles — Sushan 皇家风范的“酥山”Sushan is a dish that looks like crushed ice with milk and butter. Wang Lingran, a Chinese Tang Dynasty Poet, described how people made and enjoyed Sushan in his poem Ode to Su He Shan. According to the text, sugar was added to Sushan of different  shapes. Sometimes, Sushan was decorated with flowers and leaves to make it more beautiful.酥山看起来就像淋上牛奶和黄油的刨冰。在唐朝诗人王泠然的《苏合山赋》中详细讲了唐人制作、使用酥山的过程。酥山上加入糖,可将其变换为各种形态,辅以花朵和绿叶点缀,更显美丽诱人。His poem is cited by many scholars as evidence that Sushan is an early form of ice cream. However, only the royals and nobles were lucky enough to have large iceboxes to make this delicacy in summer.很多学者认为王泠然对酥山的描绘证明了其作为我国最早的“冰激凌”的起源,但是在那时,只有王公贵族在炎炎夏日才有这番待遇能够享受到冰凉美味的酥山。Simple, Refreshing Icy Treats简单、沁人的“冰”品Although there were no fridges in ancient times, iceboxes to store ice cubes in summer were very common in rich families by the Tang Dynasty.尽管古人没有冰箱,但发明出了储存冰块的冰盒,到了唐朝,这种器具已经在富贵人家中很普遍了。At that time, common people could only afford ice water and shaved ice. People could easily buy iced beverages on the street during the Song Dynasty. For the benefit of the community, some rich people even offered free ice water and medicine to people in need on the street for free in hot summer.但那时,普通人能享用到的“冰品”其实只有冰水和刨冰那么简单,在宋朝,冰镇饮料已经在大街小巷中普及。作为社会慈善的一部分,有些富人家还会在街上免费提供冰水和解暑药给需要的人。Mung beans and licorice were often added to ice water sold during the Song Dynasty to help prevent heat stroke.宋朝人喝的冰水中还常常加入绿豆和甘草,用来防止中暑。Resurrection from Brick-shaped Ice Cream to Fancy Sundaes从冰砖到圣代的华丽蜕变In recent years, classic Chinese brands of ice cream and popsicles are finding new ways to lure customers back, and here we see how Yimin, a time-honored Shanghai brand did the trick. 我国经典的冰糕品牌近年来不断探索新方法,吸引消费者的目光。上海的老字号益民食品厂,便是一个典型的例子。Speaking of Yimin's classic products, one has to mention its brick-shaped dessert which became one of the most popular ice cream after going on sale in the 1950s. Its popularity continued through the 1980s and 1990s, making it an important part of the childhood memory of several generations. Its size and shape resembled a soap bar. And consumers would dip it in soda water, mix it with cookies and fruits, or even use  it as a dressing for fruit salad after it melts.说到益民旗下的经典产品,不得不提那“光明冰砖”。自上世纪50年代问世以来,直到80、90年代,一直都是夏天最热门的冷饮之一,陪伴了好几代人走过了童年的夏天。冰砖的形状如一块肥皂,顾客买来不仅可以直接吃,还可以泡上苏打水,拌入曲奇饼干和水果,甚至还可以任其融化,倒在水果沙拉上吃,可谓是吃法繁多。However, in the new century, a large number of imported ice cream brands began to compete with domestic brands for more market share. In recent years, local brands eventually started to fight back after years of stagnation – including the creative "Tri-color Cup" and this year's new product: Durian Sundae. If these new delicious treats will offer you nostalgia as a bonus, why not give it a try?新世纪以来大量的外资冰激凌品牌涌入使得本土品牌的生存空间越来越小。在经历了多年的停滞不前后,近年国产品牌开始逐渐发力,推出了新款“三色杯”,今年还推出了创意满满的“榴莲圣代”。当浓醇的美味得以创新和延续,加上一丝清新的怀旧情怀,何尝不去尝试一下老字号的新产品呢?

川航奇迹备降

A Sichuan Airlines flight made an emergency landing in the southwest Chinese city of Chengdu on May 14th after a windshield on the right side of the jet's cockpit broke off. 5月14日,四川航空公司一架客机在高空巡航过程中驾驶室右侧舷窗突然爆裂,随后在成都紧急迫降。No passengers were injured in the incident but the pilot sitting in the right seat, who is usually the first officer, suffered scratches and a waist sprain. A cabin crew member was also injured in the descent. The cause of the incident is still under investigation.机上乘客没有受伤报告,但是靠近破损舷窗的副驾驶有多处擦伤以及腰部扭伤。此外还有一名乘务人员也在飞机下降中受伤。事故的原因仍然在调查之中。The flight, Sichuan Airlines 3U8633, left the central Chinese municipality of Chongqing on Monday morning and was bound for the Tibetan capital of Lhasa. According to flight tracking website FlightRadar24, the aircraft was an Airbus A319. A spokeswoman for Airbus said that the planemaker would provide all necessary support upon request by the CAAC and Sichuan Airlines.事发的航班是川航执飞的3U8633航班,当天早晨从重庆飞往西藏拉萨。根据航班跟踪网站FlightRadar24的数据,这架飞机的型号是空客A319。随后空客的一名发言人表示,他们将尽一切的努力,为民航总局以及川航提供技术上的帮助。Pictures showed the plane missing one of its cockpit windows and damage to its cockpit controls. Chinese social media users praised the pilots for landing the flight safely without incurring any passenger injuries and called them “heroes”.网上流传的图片中可以看到,飞机驾驶舱的一整块舷窗都已不见了踪影,机内的操控设备也严重受损。社交媒体上,群众纷纷为飞行员的英勇事迹点赞,他们在如此紧急和困难的条件下成功使飞机降落,把乘客安然无恙地送回地面,堪称奇迹。Incidents involving cracked windshields do happen on a regular basis due to occurrences such as bird or lightning strikes but ones involving entire windshields coming off are rare. It is also remarkable that the pilots managed to deal with the emergency as the temperature was as low as -40 degrees Celsius and the gushing wind disabled proper communication. 飞机舷窗破裂的事故偶有发生,通常是受到了飞鸟撞击和雷击,但是像这种整块舷窗破裂的情况还是十分少见的。本次事故中,舷窗破裂后驾驶舱的气压骤降,温度跌至零下四十多度,急速灌入的风几乎让通讯无法进行,即便如此机组仍然力挽狂澜,的确可以称之为“壮举”。Incidents Déjà vu 似曾相识的事故/199006Shortly after British Airways flight 5390 left Birmingham Airport in England for Málaga Airport in Spain on 10 June 1990, an improperly installed windscreen panel separated from its frame, causing the plane's captain to be blown partially out of the aircraft.

第八届教学大赛二等奖刘颖授课

“每一次经历都是生活给予的宝贵经验,是成长的必然。”★参赛感言★对于初登讲台两年的我来说,有幸参加“外教社杯”全国高校外语教学大赛是一次难得的锻炼,是一次宝贵的经历,更是一次痛并快乐着的成长。从校内选拔赛到北京赛区的决赛和总决赛,我怀着“初生牛犊”的精神,一路走来还算顺利,并且幸运地获得了参加全国决赛的机会。然而,随着比赛的推进,我越来越多地发现了自己的问题和不足。对于抽到的文本如何处理?准备做成什么课?亮点在哪儿?活动和课堂怎么组织?在20分钟内如何有效、有趣地调动完全陌生的学生?这些问题都让我寝食不安。同时,我也发现年轻的我在很多方面都还非常稚嫩,不论是对于职业英语职业性的把握,对英语语言本身的理解和感悟,还是对于高职英语课堂的掌控和组织。好在,我身后有一个温暖的集体,不论是北京电子科技职业学院和基础学院外语教学部的领导、同事们,还是北京市大学英语研究会高职分会的专家们,都给了我很多帮助、鼓励和支持,让我有勇气去更大的舞台上展示自己,向更多的优秀教师学习。在此,我要向他们表示衷心的感谢!准备和参加全国决赛是值得我铭记的经历。紧张的三天赛程,我看到了其他省、市、地区的高职英语教师们的风采。他们的钻研、专注、创新、热情和专业,他们对于学生、教材和课堂的掌控值得我不断模仿、学习。而在比赛过程中,专家评委们犀利的提问和精准的点评都让我记忆犹新。犹记颁奖典礼上李力教授对所有英语教师提出的两点建议:一是要不断地提高自己的英语素养;二是要跳出固定思维、不断创新。这两点对我来说真是振聋发聩。虽刚登上讲台不久,但在备赛的过程中我依然感觉到自己陷入了某种“固定模式”的怪圈,不想或不敢去创新。可是只有当一个老师的思想、观念、知识一直是新鲜的,她的课堂才是充满活力和吸引力的。此外,作为一名英语老师,听说读写等英语语言能力不是问题,然而语言素养是否到位却是我之前没有做过太多思考的问题。要成为一名合格的英语老师,提升自己的专业水平和职业素养,一刻也不可懈怠。最后,十分感谢上海外语教育出版社给外语教师提供这样的机会和平台,让我们可以和全国各地的同行交流,相互学习,共同探讨高职英语教学规律、交流教学经验。衷心祝福“外教社杯”全国高校外语教学大赛越办越好!授课点评专家:陈明娟教授刘颖老师语言能力强,口语流利,思维清晰,表达清楚,上课激情四射,仪态自然大方,自信且具亲和力。本节课的教学特色可归结为:目标设定清晰,节奏掌控恰当;教学过程流畅,教学气氛轻松;教学内容清晰,驾驭课堂能力强。刘颖老师的教学设计与实施均较为成功。教学中师生互动频繁,教学风格自如放松,学生保持着较高的学习热情。刘老师讲授的课文是 “Ice road truckers”,她设定了三个教学目标,即知识层面的掌握关键词汇和词组,技能层面的学会概括文章大意、表达个人观点,情感层面的学会团队合作。三个教学目标基本都在本堂课中得以实现。刘老师把本堂课设定为 extensive reading,用“What is the coolest job in your mind?”开讲,通过引发学生讨论、给出不同回答,引出本课 ice road truckers这个主题。刘老师对文章的处理进行了精心设计,充分考虑了高职学生的特点,设计多样的练习形式,创设有效的学习环境,充分调动学生的学习积极性,体现了以学生为中心的课堂教学思想。在处理文章第一、第二段时,刘老师让学生带着 “What do ice road truckers do?”“Is their work important?”“Why or why not?”等问题阅读,并用加拿大地图形象地介绍加拿大北部的地理位置和严峻气候,以帮助学生了解背景知识,熟悉 ice road truckers 这一职业及其重要性。在处理第三、第四、第五段时,刘老师把学生分成不同的小组,每一组分别围绕 why dangerous、how to ensure safety、what qualities等三个方面讨论不同的段落,培养学生的概括能力。在讨论阶段,刘老师充分调动学生的积极性,和学生一起讨论为什么有人愿意从事 ice road trucker的工作,并从四个方面帮助学生对这一工作进行描述,使学生学会如何描述工作。最为出彩的是最后一部分,刘老师以文章最后一段中 Dianne Rowland企图阻止其丈夫放弃 ice road trucker的工作为情景,要求学生设计对话并表演。学生代表表现出色,给评委留下深刻印象。整堂课自然流畅,刘老师机智灵活,善于鼓励学生,善于调动学生的积极性,能充分利用板书、纸条、视频等增加课程的可视性和形象性,也能不时给予学生指导和帮助,课堂效果好,目标实现得好。但本堂课仍然存在一些不足:1.刘老师上课充满激情,声音洪亮,但略显夸张,有表演的痕迹。2.对于关键词汇和词组的解释和强调不够,知识层面目标的实现略为不足。3.缺乏对文章长句和难句的强调和解释。

第八届教学大赛二等奖姚素华授课

“Shanghai, I came. I conquered. The experience will be engraved in my memory forever. Thank you all, my beloved friends and colleagues. The prize is for us!”★参赛感言★有幸代表广东省参加此次全国性的比赛,实为教学经历上的里程碑。感谢外教社搭建这样一个平台,感谢评委老师们精彩的提问和点评,感谢广东交通职业技术学院基础部朱东华主任和教研室张彦杰主任的全力支持和用心指导,感谢去年广东参赛选手陈海涛老师以及各位同窗好友的帮助。在此次盛事中,广东赛区还荣获了最佳组织奖,获得了一赛双赢的好成绩!作为一名普通的英语教师,我的工作就是让学生在课堂中尽可能多学知识并掌握学知识的方法,通过英语更多了解外面的世界,更好地提高自身的人文素养。一直以来,我都尽己所能地备好课、上好课,积极与学生交流,了解他们的想法,设计出适合他们的水平、兴趣和目标的教学活动。在备赛的两个月中,我几乎每天都在为之奋斗,这个过程可谓“痛并快乐着”。我研读了“外语教学网”微信公众号的“教学风采”栏目以及每年外教社出版的大赛相关书籍,分析了往届优秀获奖选手的现场授课和即兴说课,对比赛流程和评委风格进行了了解,积累了大量学习笔记。在得知进入全国总决赛之后,我便将赛场上所有可能出现的问题罗列出来,虚心请教在去年国赛中荣获二等奖的陈海涛老师。陈老师经验丰富,对我的问题一一作了回答,对我进行了耐心的指导。离国赛还有两周时开始网上选题,我所抽到的题目是全球PwC主席有关上海作为智慧城市之未来的一篇演讲。文章术语众多,语句复杂,信息量大。现场授课仅有20分钟,如何简洁、清晰地把教学重点完整、连贯地呈现出来是个考验。为此,我先对整篇文章的主线和背景进行了全面而细致的梳理,不放过任何一个单词,又与研究生同学和同事们讨论文章内容和教学思路,思学生所想,教学生所需,集思广益,反复推敲。然后进行全文翻译润色,不断修改课件和授课稿。最后,和学生进行教学演练,继续完善教学思路。特此感谢朱主任和张老师,二位在观摩演练之后提出很多宝贵的建议,让我受益匪浅。在两周的准备过程中,我侧重于全国决赛授课环节的准备,而对总决赛的说课环节有所忽略,因此在说课环节倍感压力,未能像在省赛中那样稳定、自如地发挥,略感遗憾。但人生就是惊喜与遗憾的交织,不是吗?当前大学英语正面临着重要改革,其重要性被逐渐削弱。我想起在一次全国性的教学培训中,主讲人问了在场各位老师一个问题:“大学英语课堂最终能带给学生什么?”有些老师说“英语知识”,有些老师说“考试技巧”。我当时的想法是,让学生通过英语了解和学习国外先进的知识和技术,这与主讲老师的想法不谋而合——“增强我国的综合国力”。推行“一带一路”使我们国家对复合型人才的需求日益急迫,再高水平的翻译人员也无法替代专业技术人士去解决技术层面上的问题。这也是我在宝洁公司担任越洋培训翻译中的深刻感受。希望大学英语课堂能为高职高专学子在成为复合型技术人才的道路上做好铺垫。以上便是个人在此次教学比赛以及大学英语教学中的一点体会。再次感谢外教社和广交院提供宝贵的机会,让我得以在教学的道路上越走越远、越走越深、越走越广。授课点评专家:曾用强教授姚素华老师讲授的课文是“ Shanghai's future as a connected, smart city”。她首先以一张学生熟悉的“双十一”宣传画引入 online shopping这一概念,继而引出现代中国的新四大发明: online shopping、online payment、high-speed rail、shared bike,以此导入主题“ Shanghai's future as a connected, smart city”。大约两分钟的导入之后,姚老师介绍了教学目标:掌握文章大意、学习课文中的词语及构词法(以 -ity为后缀的派生词)、分析并概括上海是如何成为一座真正的智慧城市的。姚老师用自我陈述的方式介绍了课文中提到的几项现代技术,然后要求学生完成阅读理解练习(填空题),最后与学生边讨论边对答案,并引出课文中的重点词语,着重讲解了后缀 -it的用法,比如 mobile → mobility、connect → connectivity等。姚老师的教学设计重点在课文分析。她首先向学生介绍了课文分析的框架: topic ─ illustration ─ example ─ ending,然后基于这个框架分析了课文的三大部分(分别介绍 improved health、smart business和mobile technology等三大领域),教学方法采用“问答+填空”。姚老师最后应用思维导图概括了课文的讲解,给予学生很直观的感受。姚老师的这一环节的教学比较成功:引导学生如何学习(课文分析的框架)、指导学生完成学习(互动+训练)、教导学生概括学习(思维导图)。姚老师以角色扮演来结束本课的教学:学生带她的爷爷逛上海,介绍上海生活中的现代技术的应用,让爷爷打开眼界。角色扮演是一种很好的教学形式,让学生有身临其境的感觉,容易激发学生真实的语言产出。但有点遗憾的是,在本节课中,学生类似的真实语言产出有点少,大多数时候学生只是在做练习,然后对答案。姚老师的教学特征可以概括为“平实”:首先,在整个教学过程中,她对待学生很“平和”,总是面带微笑,语音、语调也是不急不慢,一点也不做作;其次,她的教学设计很“平常”,遵循了常规的“导入——讲解(从课文到语言点)——概括——布置作业”;最后,她的教学组织很“平稳”,设计了贴近学生实际水平的练习,每个教学环节之间的衔接很自然、顺畅,时间把控得比较合理。“平实”的教学风格有时候会给人一种“缺乏激情,创新不足”的感觉,所以我的建议是:保持自己的“平实”风格,通过训练方式的“创新”,激发学生的“激情”。也就是说,在今后的教学中,增加让学生主动参与的、互动性强的训练方式(如角色扮演、仿真任务等),最大化激发学生真实的语言产出。

VOA常速:经常完全眨眼有助于避免干眼病燕山大学 刘立军 编写 TRANSCRIPTKids are addicted to cell phones, tablets, anything with electronic screens. The problem is it’s bad for their eyes.What we’re beginning to see is now with the use particularly of screens, the digital screens, tablets, smart phones that actually even children are reporting dry eyes.Tears contain oil. In this YouTube video, the doctor is pointing out the oil glands that are in the eyelid.The tear film on the front of your eyes is there all the time, not just when you cry. It’s less than a tenth of the thickness of a human hair, but without it, you wouldn’t see at all.With kids spending more time in front of a screen, for pleasure and for school, many may be at risk without knowing it. When you concentrate very hard on a task, such as on a computer screen, you blink less and also instead of fully blinking, you partially blink. And so what’s happening is damage is being done to the front of the eye.Tears aren’t being produced. They evaporate and leave behind the salty content of the tear which can do further damage to your eyes. But now there is an app to diagnose dry eyes. At this demonstration in London, the app asks users to answer simple questions to determine how long they can comfortably stare at a computer screen without blinking. We’re actually using the technology but that could cause problems if you use a lot of it to actually help us with the diagnosis.Those who try the app are then tested for dry eye. But doctors say even if you don’t have the app, make sure to blink fully, and blink often whenever you’re in front of a tablet or computer screen and remind your children to do the same.Carol Pearson, VOA News.Adapted from http://www.kekenet.com/broadcast/201808/562227.shtml VOCABULARY1. gland n. an organ in a person's or an animal's body that produces a substance for the body to use.
