“勇闯51区”——“地球人”的小欢聚

Events involving thousands of Earthlings answering an internet buzz about an invitation to “Storm Area 51” in the Nevada desert have been mostly festive. After a weekend of camping and partying, the Earthlings from around the globe headed home in peace.数千名“地球人”响应网络的号召,来到内华达州的沙漠地带参与“勇闯51区”的活动。历经一个周末的野营和派对后,参与者们平静地启程离开,在欢乐中宣告活动的收尾。Visitors hailed from France, Russia, Germany, Peru, Sweden, Australia and many U.S. states — in answer to the Internet post “Storm Area 51” in June suggesting that if enough people rushed a military base to "see them aliens" at 3 a.m. Sept. 20, authorities couldn't stop everyone. More than 2 million netizens clicked their interest, but in the end only a few thousand made the trip to the tiny Nevada desert city of Rachel, population about 50, a more than two-hour drive north of Las Vegas.专门为此次“行动”而来的游客来自世界各地,包括法国、俄罗斯、德国、秘鲁、瑞典、澳大利亚等等,当然还有美国多个州的爱好者——他们均是为了响应今年6月网上发起的“勇闯51区”的活动倡议,相约在9月20日凌晨3点在此处相约“外星人”;大家想当然地以为只要有够多的爱好者冲进该军事基地参与活动,军方便不会阻止。虽然超过200万的网民点击了“感兴趣”,但最终到场的只有数千人。据悉,要来到“据点”,参与者需要从拉斯维加斯驾车两个多小时,来到人口仅有50的雷切尔小镇。Did anyone find actual extraterrestrials or UFOs? Well, if you exclude the masked and costumed beings posing for photos and cavorting in the desert, then the answer is no. However, the participants felt a great sense of community. It started as a joke and turned out to be a joyous gathering to know each other.那么究竟有没有人看到“天外来客”或者“UFO”呢?要是你排除了现场那些游来荡去、精心打扮成外星人的爱好者,那么这个答案很显然是否定的。但是,对于参与者来说,这项活动本身就是一场外星人爱好者们欢聚的盛会。倡议提出之时便不是正儿八经的“勇闯”,而是参与者们彼此认识,沟通了解的绝佳机会。What on Earth is "Area 51"?那么,究竟什么是“51区”?For decades, Nevada's Area 51 Air Force facility has represented the eye of a conspiratorial hurricane that swirls around "evidence" that aliens exist and are hiding behind its walls. Books, TV shows, and films have tried to glimpse beyond its stark signs warning against trespassers.几十年来,内华达州的这座“51区”空军基地一直是被认为是研究“外星人”的秘密基地。大量的书籍、电视节目、电影等纷纷将关注的焦点投向它,试图透过其高高的围墙一探内部的究竟。What exactly goes on inside of Area 51 has led to decades of wild speculation. There are, of course, the alien conspiracies that galactic visitors are tucked away somewhere inside. There are plenty of rumors. Some even believe that the U.S. government filmed the 1969 moon landing in one of the base's hangars.“51区”内部究竟酝酿着什么,一直以来都引发着各种猜想。最引人注意的莫过于“外星人”一说,认为基地里藏有天外来客。谣言种种,难以求证。有些人甚至认为1969年美国登月实际上是在该区内部的某个摄影棚内拍摄完成的。For all the myths and legends, what's true is that Area 51 is real and still very active. There may not be aliens or a moon landing movie set inside those fences, but something is going on and only a select few are privy to what's happening further down that closely-monitored wind-swept Nevada road.在有关“51区”重重的神话和传闻之下,能够确定的是,它是真实存在的,且仍在活跃运行。在隔离区内或许没有外星人或者“假登月”的摄影棚,但是在这所荒凉地带的隔离区里,只有极少一部分人有权限能够进入,从事鲜为人知的工作。While the lore around Area 51 may be nothing more than imaginative fiction, that won't stop people from gawking just beyond those chain link fences. As aerospace historian Peter Merlin puts it, “at the most basic level, anytime you have something secret or forbidden, it's human nature, and you want to find out what it is.”尽管有关“51区”的传闻如幻想小说般不大可信,但依然阻止不了人们好奇的目光。就如航天历史学家彼得·梅林所说,“从根本上来看,只要是秘而不宣的事情,总是能自然而然地引起人们极大的好奇心,这其实是人性的一部分。”VOCABULARYEarthling: n. 地球人(常用于科幻小说中)extraterrestrial: n. 外星人;星外来客galactic: adj. 星系的lore: n. 传说;传闻

对猫咪不再过敏

Good news for cat lovers who can't stop sneezing around their furry friends: researchers have developed a potential new cat allergy vaccine.喜欢“撸猫”却饱受过敏困扰的朋友们,好消息来啦!研究人员研发了一种新的疫苗,能够显著降低猫咪的致敏水平,让爱猫一族都能抱上毛茸茸的可爱猫咪。The preliminary study showed that the vaccine called "HypoPet" is able to target and neutralize the major cat allergen "Fel d 1" — a cat protein that's secreted into a cat's saliva and tears, as well as found on the animal's pelt — that causes humans' allergic reactions. The researchers reported that the vaccine is "well-tolerated".初步研究结果表明,这款名为“HypoPet”的疫苗能够中和宠物猫身上含有的过敏原“Fel d 1”蛋白。该蛋白存在于猫咪的唾液和泪液以及全身的毛发中,而此物质便是导致人类过敏的罪魁祸首。研究人员表示,该疫苗当前在猫咪身上“耐受良好”。But unlike most vaccines, the shot is for the cat — not its human owners. In other words, the vaccine immunizes cats "against their own major allergen, Fel d 1," according to the study.和大多数的疫苗不同,这款疫苗的接种对象不是猫的主人,而是猫咪。换句话说,该疫苗让猫咪具备“抵抗自身Fel d 1过敏原”的免疫能力。The vaccine would help millions of pet owners who are allergic to their animals. The proteins found in a pet's dander, skin flakes, saliva and urine can cause an allergic reaction, like sniffling, sneezing, itchiness and watery eyes, or aggravate asthma symptoms in some people.这款疫苗将使数百万对宠物过敏的主人受益。宠物的毛发、皮屑、唾液和尿液中含有的过敏原常常会导致易敏人群发生过敏反应,轻者会出现打喷嚏、皮肤瘙痒和眼睛流泪等症状,重者则会加重哮喘。The vaccine has the potential to lead to a lower allergenic cat, and the benefits of that are two-fold. Both human subjects and animals could profit from this treatment because allergic cat owners would reduce their risk of developing chronic diseases, such as asthma, and become more tolerant of their cats, which therefore could stay in the households and not need to be relinquished to animal shelters.这款疫苗能够降低猫的致敏性,带来双重好处:无论是猫的主人还是猫咪都能从中获益,猫主人患上诸如哮喘等慢性病的风险降低,从而增加对猫咪的容忍度,改变猫咪被遗弃或被送往动物收容所的命运。However, more research is still needed — including with human subjects — and it will be a while before the vaccine is available. In the meantime, you can help keep sneezing and watery eyes at bay by keeping pets out of your bedroom. Professionals also recommend using a double or micro-filter bag in the vacuum to reduce the amount of pet allergen in carpeting, which can end up in the air you breathe, and use HEPA air cleaners, which help remove allergenic particles from the air so you can breathe easier.然而,此疫苗上市仍需时日,在正式推出前还需要进一步研究,包括其对人类的潜在影响。在此期间,宠物主可以通过防止猫咪进入卧室活动来减少过敏反应。专家还推荐,在清洁地毯时,在吸尘器内安装双重尘袋或者微滤尘袋,从而减少空气中的宠物过敏原。此外,使用带有HEPA滤网的空气净化器,也能过滤空气中的致敏微粒,让呼吸更为通畅。VOCABULARYpreliminary: adj. 初步的allergen: n. 过敏原pelt: n. (动物的)毛皮relinquish: v. 放弃

让“少年的你”远离霸凌伤害

郭逸纯 供稿Last month, a long-awaited Chinese youth drama Better Days hit cinemas across China. The film tells a story about how the two teenagers Nian and Bei’s fates were changed by a school bullying incident. Nian, a high school student single-mindedly preparing for the college entrance examination, fell victim to brutal school bullying and has since then got into big trouble. Fate brought her together with a punk Bei who promised to protect her. But unfortunately, the two were then embroiled in a murder investigation which drastically changed their life.十月,一部令人期待已久的青春片《少年的你》在中国各大影院火热上映。影片讲述了陈念和小北两位少年因一起校园暴力事件而发生命运转变的故事。陈念是一名高中生,原本一心一意备战高考的她,却不幸遭受恶劣的校园霸凌,陷入种种困境。就在这时,她偶然遇见了一位名叫小北的小混混,小北答应暗中保护她免受欺凌,但没想到,两位少年接着又卷入一件谋杀案中,两人的人生轨迹从此彻底改变。This film has not only won a huge box office success since its debut, but also brought the issue of school bullying to the public’s attention. School violence and bullying are major problems worldwide. According to a report published by UNESCO earlier this year, almost one in three students has been bullied by their peers at school at least once in the past month before the release of the report.该片一经上映便创造了票房佳绩,同时,影片也引发了公众对校园霸凌的关注。校园暴力和校园霸凌在世界范围内都屡见不鲜。联合国教科文组织2019年发布的一份报告显示,就在该报告发布前的一个月内,就有近三分之一的学生至少遭受过一次校园霸凌。Violence and bullying can leave a lasting scar on the victims and have a profound negative impact on their daily life, mental health and academic performance. Students who are frequently bullied may feel it difficult to trust in people around them and build friendly relationships with others. As a result, they are more likely to feel like an outsider at school and thus become isolated and depressed. Haunted by the bullying experience, students may suffer nightmares and be distracted in class. In worse case scenarios, they may play truant, drop out of school or even contemplate suicide. According to a study, many victims still live under the shadow of bullying in their childhood after they grow up. The study suggests that the victims of bullying who are described as “low in self-esteem and unpopular with peers” are more likely to smoke regularly, suffer from alcohol or drug abuse, or develop a psychiatric disorder after growing into adults.暴力和霸凌往往给受害者的心灵留下难以愈合的创伤,严重影响着他们的日常生活、心理健康和学业表现。频遭霸凌的学生往往难以信任他人,结交朋友,这让他们越发觉得自己在学校里格格不入,从而渐渐地变得性格孤僻、郁郁寡欢。身受欺凌的不幸遭遇萦绕在这些受害学生的心头,可能导致他们深陷梦魇,在课堂上分心走神。更糟糕的是,他们还可能选择逃课、辍学甚至企图自杀。一项研究表明,很多儿时遭受校园霸凌的受害者长大后仍未走出这段阴影,这些在人们看来自卑而不受欢迎的受害者在长大成人后,往往更容易养成抽烟、酗酒和吸毒的习惯,甚至可能身患精神疾病。To protect juveniles from school violence and bullying, parents, schools and governments should make joint efforts. Many young bullies are unaware of the devastating consequences of their manipulative and aggressive behaviors because their parents and teachers fail to discipline them and teach them to distinguish between right and wrong. At the same time, some bullies may be victims of certain emotional problems themselves because of their violent or neglectful parents. Therefore, parents and teachers should shoulder responsibility to teach children moral values and empathy as their role models and pay more attention to children’s psychological well-being. Besides, legislation should be in place to safeguard children’s rights and prevent juvenile delinquency. On October 26, a revised draft law on the protection of minors required schools to establish effective mechanisms to prevent school bullying and listed some specific measures to deal with this problem.家长、学校和政府应当协力保护青少年免受暴力和校园霸凌毒害。很多校园“小恶霸”并不知道他们盛气凌人、肆意摆布他人的行为会造成怎样严峻的后果,这是因为家长和老师对他们缺乏管教,没有教导他们学会辨别是非。另外,一些“小恶霸”或许自身也是受害者,他们在父母长期的家庭暴力或疏于关心中也遭受着某些情感问题。因此,家长和老师应当担起责任,言传身教,培养孩子形成良好的道德观和同理心,并且更多地关注孩子的心理健康。另外,国家应完善相关法律保护未成年人的合法权益,防止青少年犯罪。10月26日,一部关于保护未成年人的法律修订草案引发社会关注,修订草案中要求学校建立霸凌预防制度,并提出了解决校园霸凌问题的具体措施。No child is born to be a vicious bully and no child should be left under the shadow of violence. With the intervention of families, schools and governments, we are sure to put an end to school violence and bullying and promise every child a better day.没有哪个孩子生来就是凶狠的“小恶霸”,也没有哪个孩子理应生活在暴力的阴影之下。相信在家庭、学校和政府的共同努力下,“少年的你”终将远离校园霸凌,从而拥抱更美好的明天。VOCABULARYsingle-minded adj. 一心一意的,专心致志的embroil v. 使卷入,使陷入(embroil sb. in sth.)manipulative adj. 摆布他人的juvenile delinquency 青少年犯罪minor n. 未成年人

Officials plan to extend the project to a total of 10 countries. The goal is to prevent the premature deaths of 6 million women and children by 2030.Raj Shah is president of the Rockefeller Foundation, which leads the project.

"My son died in the hospital when we found out that he had been binge drinking and he died from alcohol poisoning, from the effects of alcohol poisoning. I was home from work and then I was literally grieving and laying on a couch and I couldn’t do anything." Each year in the U.S. more than 1,800 college students between the ages of 18 and 24 die from alcohol-related injuries including motor vehicle crashes, the National Survey on Drug Use and Health reports. Despite the potential risks taking the edge off stress is why some students say they drink.Definitely for students at least nowadays a lot of it is stress, students like to work hard, play hard mentality. And they after a long week of classes and overachieving, they want to head to the bar, head to the club, head to their friends house and drink. But experts disagree that drinking relieves stress. So there is a misperception a lot of students will say that they drink to relieve stress. But in fact the studies and literature show that when students are drinking it actually increases stress in their lives.Mitchell urges for stricter alcohol policies at colleges. We encourage colleges to adopt policies that reduce the access to alcohol that send the message to students that alcohol and excessive alcohol use are not a normal part of your college experience. Ciammetti who now runs a non-profit to educate young people about the harms of binge drinking admits that as a parent she should have been more vigilant of her son’s activities. "What I do believe is that as a parent now when if anybody asks me I say go into their rooms, go into their college dorms and go see what is there. Now looking back I would do anything I could to get Christian back. And it’s too late.

VOA慢速:吃巧克力能改善视力吗燕山大学 刘立军 编写 TRANSCRIPTResearchers have sad news for chocolate lovers. They found that eating dark chocolate does not improve people's eyesight as had been thought.An earlier report suggested that some aspects of eyesight improved within one or two hours of eating chocolate. The new study found no changes in vision or blood flow after volunteers ate about 20 grams of dark chocolate. Both studies, however, involved only a small number of test subjects.With two similar-sized tests producing opposite results, "more research is needed," said the organizers of the latest study. The lead researcher was Jacob Siedlecki of Ludwig-Maximilians-University in Munich, Germany.Additional testing with larger sample sizes would be needed to rule in or out possible long-term benefits," the researchers wrote. Their report appears in the medical publication JAMA Ophthalmology.The reason for suspecting dark chocolate might help with vision is that the sweet treat has plenty of flavonoids, which are antioxidants.Antioxidants are man-made or natural substances that may prevent or delay some forms of cell damage. Studies have shown that foods with high levels of antioxidants can reduce the risk of an age-related vision problem called macular degeneration.To see if the earlier study on chocolate could be repeated, Siedlecki and his team found 22 healthy volunteers, ages 20 to 62, who had good eyesight.The volunteers were asked to eat either a 20-gram piece of dark chocolate or a 7.5-gram piece of milk chocolate. The piece of dark chocolate contained 400 milligrams of flavanoids, while the milk chocolate had about 5 milligrams of flavanoids.Volunteers' eyes were examined with a relatively new, high-tech scanner that shows blood vessels in detail. The volunteers were tested before they ate the chocolate and again two hours later.Siedlecki's team was looking for signs that the chocolate had enlarged blood vessels in the eye. This means volunteers were getting better blood flow.Volunteers were also given low-technology vision tests similar to the ones used in the earlier chocolate study.A week after the test, the people who got dark chocolate the first time were given milk chocolate, and those who had milk chocolate the first time were given dark chocolate.The researchers said they found no difference in either test when volunteers ate dark chocolate or milk chocolate.Doctor Gareth Lema was a little sad to read the latest findings. "I like chocolate," he explained.While the new study failed to show any health benefit to eating a single piece of chocolate, "that doesn't mean eating it over the long term isn't beneficial," said Lema. He works at the New York Eye and Ear Infirmary of Mount Sinai in New York City."Neither study really showed that if you eat a piece of chocolate, you'll have (great) vision," Lema added.Doctor Jay Chhablani agreed."Someone has to do a long-term study comparing dark chocolate to milk chocolate," he said. Chhablani is an associate professor of ophthalmology at the University of Pittsburgh School of Medicine.Both men know it will be easy to find volunteers.I'm Susan Shand.Adapted from http://www.kekenet.com/broadcast/201910/596151.shtml VOCABULARY1. ophthalmology n.

第九届教学大赛商务英语专业组一等奖余静授课

授课点评:余静老师的教学设计比较完整,包括1)课前准备(小组项目、模拟电视采访);2)课堂教学(课文精讲、重点词汇联系、微型调研等);3)课外作业(教材自带作业、用学到的新词写总结、采访录像等);4)效果评估(诊断性测试、总结性测试、同学评估等)四个环节,形式多样,内容丰富,有利于多方面调动学生积极性和多角度训练学生的商务英语能力。授课中,余静教态自然,英语流利,语音语调总体准确,与商务有关的知识与技能了解较多,有较强的课堂掌控和应变能力,展现了一名商务英语教师的良好素质。余静在授课中善于运用多媒体。比如,她展示文艺复兴初期和晚期的两幅油画,要求学生通过比较找出差别。她还用动态的几何图形来描述贸易、科技和艺术在文艺复兴中的互动作用,取得了较好的教学效果。不过,有些比喻似乎解读过度。比如,她说贸易加上科技和艺术,文艺复兴就有了三角形的稳定(视频7’00”)。实际上,课文作者强调贸易这个因素,是为了说明文艺复兴起因的多样性,而不是稳定性。实际上,余静后来(视频17’30”)在布置作业时,还让学生试用(四)方形、五边形来形容人生、商业模式的多样性,这同前面强调稳定性在逻辑上就矛盾了。其他选手的授课重点是英语,而余静把商务和英语结合起来讲,体现了商务英语教师的特色,对此应予以充分肯定和鼓励。不过在授课中,有时低估了讲清某些复杂过程所需的时间。比如,也许是时间紧迫,她对bill of exchange在中世纪的运作方式的解释(视频11’50”)过于简略,且与PPT上的定义不相吻合,容易造成理解困难甚至误解。在回答评委提问时,余静理解准确,反应迅速,表达清晰,回答切题。总而言之,作为一名年轻的商务英语教师,余静在授课中展现出比较突出的专业素质,有很大的发展潜力。点评专家:陈准民教授

说课点评:该选手开始说课时显得有些紧张,说话不很流畅。尽管如此,选手对说课的内容把握得还不错。她首先介绍该课用四节课完成。之后,借助板书,选手将教学目标展示得很清楚(1’16’’)。目标中包含了语言要点、对课文篇章的主旨和结构的掌握、学习商务英语写作技能及提高批评性思维能力。该选手继续借助板书,将教学过程介绍得有条不紊(2’37’’);其教学过程分为四个部分:背景知识介绍、课文分析、学生活动(聚焦提高批判性思维能力)、总结及作业布置。说课伊始,很有必要将教学的目标和教学过程及教学内容告诉学生。该选手这方面做得很好。紧接着选手介绍其教学方法(3’49’’):交际教学法和任务型教学法交替使用。她对这两种教学法做了阐释,并与教学目标中的“提高学生批判性思维能力”结合起来。这符合教学逻辑,使得教学过程中的每个环节有机地关联起来了。介绍完了教学目标之后,选手开始介绍上课的具体内容。刚开始选手阐释得不太流畅,出现一些不该有的停顿(5’9’’),这说明选手在备课时对说课的内容把握得不是很好。不过,在分析课文篇章时选手表现得还不错,她做到了迅速、清楚、准确地传递相关信息。在接下去的说课过程中,选手基本表现自然,对课文的主旨用一句话高度概括出来了。选手较详细地阐述了课文中商务英语语言的教学内容和方法(6’40’’),通过让学生利用语料库或其他方法去获得课文中一些关键的商务英语语汇的理解;通过真实的例子,让学生学会理解和使用课文中的语汇。这是一种行之有效的教学方法,调动了学生的积极性。不过,在课堂教学过程中不宜让学生花太多时间去完成该项任务。选手最好能在阐释教学方法过程中说明这一点。在说课的最后一部分,即说课的重点部分时(7’22’),该选手较之前面说课表现得更自然、更熟练。为了提高学生的批判性思维能力,选手计划给学生提供与课文相关的案例,要求他们对案例进行分析研究以帮助学生提高批判性思维能力。该选手在最后的讲解及后面布置课后作业时仍然能将课文的主旨和课文中的一些具体内容,如“商务会议”、“商务谈判”结合起来,并要求学生对比分析一些国家do business的特点(8’50’’),这既训练了学生的独立思维能力,又将学生的课后作业与课文的主题紧密结合起来了,使该选手说课的逻辑结构更为合理。选手在回答评委问题的环节中(10’11’’)表现较好,能抓住评委问题的关键给予较为合理的回答,尤其在回答第二个问题“Negotiators may not be the decision-makers”时,选手反应迅速、条理清楚,能自圆其说。总体看来,该选手的说课较之其决赛中的讲课略微逊色,显得有些紧张,有时过多地依赖准备的笔记。不过,在说课的最后几分钟,选手表现自然些。尽管如此,该选手在说课过程中基本做到了脉络清晰、内容翔实、解释到位、逻辑合理。如果该选手在说课过程中借助几张PPT展示,结合适当的板书,能更好地展示说课的内容,可以收到更佳的说课效果。点评专家:翁凤翔教授
