探索“万物互联”的世界

郭逸纯 供稿Have you dreamed of having a smart home? Once you walk into your living room, the room identifies you and prepares everything from air conditioning to lightening for you according to a cloud-based profile of your preferences. Have a tiring day at work? The room knows it, and starts to play some soothing classical music to help you get relaxed. When you walk to the refrigerator, it not only tells you what are in it, but also tells you what's the perfect meal you can make with the stuff that you already have based on your mood and maybe even you weight loss plan.你是否幻想过拥有一个智能之家呢?你刚踏进家门,客厅便感知到你的归来,从空调到灯光,它立马根据你的云端偏好记录为你奉上一切。工作了一天身心疲惫?你的房间懂你——舒缓的古典音乐开始缓缓播放,帮你放松身心。当你向冰箱走去,它不仅告诉你有哪些食材,还能根据你的心情,甚至是你的减肥计划,告诉你这些食材能做出一份怎样的美味大餐。Maybe you have only read such things in science fictions, but they're now either already possible or on the brink of coming into being. Smart homes filled with connected products are loaded with possibilities to make our life easier, more convenient, and more comfortable. And all of these are based on what is called the Internet of Things.这种种场景也许你仅在科幻小说里领略过,但如今,其中有些“幻想”已经成为现实,有些也即将如愿以偿。许多互联智能家居产品为我们带来无限可能,让我们的生活更加简单、便利又舒适。而这一切都是建立在物联网技术的基础之上。The Internet of Things (IoT) is becoming an increasingly hot topic all around the world. It's a concept that has the potential to affect not only how we live but also how we work. But what exactly is IoT and what impact is it going to have on us?物联网正成为全球日益热门的一大话题,这一概念不仅有望影响我们的生活方式,也将改变我们的工作模式。那么,物联网究竟是何物?它又将给我们带来怎样的影响呢?Simply put, the IoT is a giant network of connected "things" (which also includes people). It's estimated that there will be 50 billion objects connected to the Internet by the year 2020. That means on average, each person will have six objects connected to the Internet. We are talking about a world blanketed with billions of sensors which can acquire real-time information from the physical objects in the real world and upload it to the Internet.简单来说,物联网就是一个将万物互联的巨大网络(这里的“物”也包括人)。截至2020年,预计将有500亿终端连网,也就是说,平均每人就可能拥有六件联网设备。那将是一个被无数传感器覆盖的世界,这些传感器能够从真实世界获取各个设备的实时数据,并上传至互联网。IoT can not only benefit our daily life, but also improve efficiency, productivity, and safety within the workplace. For example, if a machine in a factory goes down, connected sensors can immediately determine where the problem is occurring and trigger a repair request to an engineer. The IoT can also predict when a machine's life cycle is about to end, which takes a preventive maintenance approach to the next level by saving facility owners thousands of dollars on unwarranted repairs or replacements.物联网不仅能改善我们的日常生活,还能提高工作中的效率、生产力和安全性。比如,一家工厂中的某台机器出现故障,连网传感器能够立即识别出问题所在,并向工程师发送维修请求。物联网还能预测机器的使用寿命,以便帮助设备主人避免花费大量金钱进行不必要的维修或零件更换,从而将预防性检修水平提高到新的高度。On a broader scale, the IoT can also pave the way for a future of smart cities and affect almost everything in cities from lighting, parking, traffic and waste management to citizen engagement, safety and security. For example, sensors in city infrastructure can collect and exchange traffic data, and thus reduce road congestion and even avoid traffic accidents.从更广的层面来说,物联网还可以助力实现智慧城市,从照明、停车、交通、垃圾管理到市民参与、安全与防护,影响城市的方方面面。譬如,城市基础设施中安装的传感器可以收集并实现交通数据的交互,从而缓解道路拥挤,甚至避免交通事故。The IoT certainly opens the door to numerous opportunities but also to many challenges. Security is a big issue that is usually brought up. With billions of devices being connected together, what can people do to make sure that their information stays secure? Will someone be able to hack into your coffee maker and thereby get access to your entire network? Another issue that many companies are concerned about is how to deal with the massive amounts of data that all of these connected devices are going to produce. They have a long way to go to figure out a way to store, track, analyze and make good use of the vast amounts of data that will be generated.毋庸置疑,物联网打开了无数机会之门,但也带来了诸多挑战。安全问题就是人们常常提及的一个大问题。当成千上万的设备互联互通,人们如何确保自己的信息安全?会不会有人通过侵入你的咖啡机,进而侵入你的整个网络?令许多企业担忧的另一个问题是,如何处理这些互联设备产生的海量数据?要想出办法储存、追踪、分析这些数据并予以妥善应用,依然任重而道远。VOCABULARYon the brink of 濒临;临近blanket v. 覆盖preventive maintenance预防性维修,定期检修pave the way for 为……铺平道路hack into 非法侵入(计算机系统)

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

VOA慢速:大学院校排名有啥用燕山大学 刘立军 编写 TRANSCRIPTLists that rate colleges and universities are very popular among parents and students in the United States. But are published lists the best way to choose the right school?The best known ranking is probably by the magazine U.S. News & World Report. On top of the magazine's list this year are schools known around the world. They include Princeton University in New Jersey, Harvard University in Massachusetts, Columbia University in New York City, The Massachusetts Institute of Technology (MIT) in Boston, The University of Chicago and Yale University in Connecticut.U.S. News & World Report published its first "America's Best Colleges" report in 1983. Since then, some educators have questioned the published rankings and how useful they are.A number of magazines publish lists of college rankings once every year. High school students use the lists as reference guides when considering where to continue their education. There are plenty of schools to choose from. Across the country, more than 4,000 colleges and universities offer undergraduate degree programs.Last month, Forbes published its college ratings for 2019. It listed 650 schools. That represents only about 15 percent of all U.S. institutions of higher learning.The magazine's top five are a little different from those of U.S. News & World Report. They are: Harvard University, Stanford University in California, Yale University, MIT and Princeton University.Like other lists, Forbes considers things like student satisfaction, how successful college graduates are and how much money they make. The magazine adds another important piece of information: how much debt students will owe after they graduate.We spoke with education experts and people whose job is to help high school students choose the right college. All of them said students and parents should look at more than just rankings because they do not tell the whole story about a school.Ray Anderson of Virginia is a former high school principal. He now works with a service called AGM-College Advisors. It provides guidance on higher education to students and their families.Anderson says what is most important to him is knowing what the student wants, likes and is capable of doing."The focus is on who you are, and then what schools match you," Anderson said, "not matching you to the school."Anderson told VOA the published rankings can help because they have valuable information about the schools.Jeffrey Stahl agrees that rankings have limited value. In his job as a counselor at Yorktown High School in Virginia, he talks with students about colleges.Stahl says choosing a college is a very personal decision. He said that the rankings "can be helpful," but some students place too much attention on the name of a school and its position in rankings."So much about the campus environment, students, professors, cannot be shown just by ranking," Stahl said. He suggests that families use the ranking information as a starting point. Then, they should widen their search, make their own list, and go see the colleges for themselves.But David Hawkins is critical of the college rankings. He is with the National Association for College Admission Counseling. He told VOA that rankings "are not mathematically proven to measure the quality of any single college, much less to provide comparisons between colleges."Hawkins said lower ranked schools may have difficulty getting students interested in their programs."As such," he said, "the rankings have been known to create ethical problems, as institutions misreport data or otherwise seek to manipulate their ranking." Like the other experts we spoke with, he said students must look past those ratings to a gain a more factual opinion about the schools for themselves.In July, U.S. News & World Report "de-ranked" five institutions from its list for misreporting information. Because of this, the magazine said, their ranking number was "higher than they otherwise would have been." The five included the well-known University of California at Berkeley.Hawkins noted that people overseas might think the rankings come from the U.S. government. That is not true, he notes. "We try to emphasize that these are commercial publications, rather than 'official' rankings of any sort."Richard DeMillo heads the Center for 21st Century Universities at the Georgia Institute of Technology. He also is a professor at Georgia Tech - a school that moved up 13 positions on Forbes' latest list.DeMillo says, while the higher rank is "nice, it does not matter." He believes that Forbes, U.S. News & World Report and other publications are providing a service, "if you ignore the ranking part of it."For example, he finds the information about all the study programs to be useful. The ratings sometimes list lesser-known schools that might be strong in a field of study that a student is interested in.All the experts VOA spoke with had similar advice for students looking for the right college. Go visit the school, talk to the admissions officers and talk with current students."There are so many hidden gems out there!" Jeffrey Stahl said. "Just because a college doesn't make the "list" doesn't mean it doesn't have great programs and resources!"I'm Anne Ball. And I'm Dorothy Gundy.Adapted from http://www.kekenet.com/broadcast/201909/594968.shtml VOCABULARY1. counselor n. 顾问2. even / much / still less: and certainly not 更不用说;更何况。例如:No explanation was offered, still less an apology. 连个解释都不给,就更不用说道歉了。3. ethical adj. connected with beliefs and principles about what is right and wrong (有关)道德的;伦理的。例如: ethical issues/standards/questions有关道德的问题;道德标准 / 问题 the ethical problems of human embryo research人类胚胎研究的伦理问题4. manipulate v. manipulate (sb. into sth./into doing sth.)

But university officials are starting to see a sharp drop in Chinese students.Several universities have reported drops of 20 percent or more this autumn at the start of a new school term.To get more international students, some schools are advertising in other countries and working to keep the number of Chinese students they have.U.S. colleges and universities need the money paid by students from China and other countries. International students usually pay the whole tuition amount, unlike American students, many of whom ask for financial aid.University officials and observers say there are several reasons for the falling numbers of Chinese students. They include trade conflicts and political tensions between China and the United States. There also is increasing competition for college students, visa issues and the growth of China's higher education system.At Bentley University in Massachusetts, the number of new Chinese students arriving for graduate level work dropped from 110 last autumn to 70. As a result, Bentley officials are wondering whether all of its graduate programs can survive."I wouldn't describe it as catastrophically bad," said the university's president, Alison Davis-Blake. She added that the university has tried to get more students from other countries as well as from inside the United States.Large decreases in Chinese students also have been reported this autumn at the University of Vermont, which reported a 23 percent decrease. The University of Nebraska-Lincoln had a 20 percent decrease.China sends more students to study in the United States than any other country. Its 363,000 students represent more than 30 percent of all international students at U.S. universities.Parents and students in China share concerns with those in other countries about American gun violence as well as immigration issues. In May, the group NAFSA: Association of International Educators identified two main reasons for falling numbers of international students who want to study in the United States: the difficulty of getting a visa, and the social and political environment in the United States.But there are also problems that affect only Chinese students. The Trump administration has accused China of stealing U.S. intellectual property. It is looking very closely at Chinese students who ask for visas to study robotics, flight and high-tech manufacturing.In June, China warned students and other visitors to the United States about possible difficulties in getting U.S. visas.Xiong Xiong is an electrical engineering student at Beijing Jiaotong University. He said he hopes to study at a U.S. university. But he is worried about the visa process, so he plans to ask to study in Britain. "I'm concerned my visa will be affected," he said.Brad Farnsworth is vice president for international global engagement at the American Council on Education. He said that his recent travels in China suggest the claims of economic espionage are making some students think they are not welcome."The concern is a Chinese student will be met with animosity about why they are in the United States," he said.International students add an estimated $39 billion to the U.S. economy.Normally, over 5,000 Chinese students are in the colleges of engineering and business at the University of Illinois. The university recently took an insurance policy that will pay it $60 million if the money from Chinese students drops by 20 percent.Lehigh University in Pennsylvania announced this month it has agreed to pay a recruiter to help bring in more students from India. It also has been taking more interest in African countries south of the Sahara Desert, said Lehigh's Cheryl Matherly.Like many other American universities, Lehigh has begun sending employees to Beijing and Shanghai to meet with Chinese students and their parents. The employees want to ease Chinese fears about studying in the U.S. and show that their university wants Chinese students.I'm Jonathan Evans.Adapted from http://www.kekenet.com/broadcast/201909/595669.shtml VOCABULARY1. catastrophe n. a sudden event that causes many people to suffer 灾难;灾祸;横祸。例如:Early warnings of rising water levels prevented another major catastrophe. 提前发出的洪水水位上涨警报防止了又一次的重大灾害。2. espionage n.

There also is (Q7) increasing competition for college students, (Q8) visa issues and the growth of China's higher education system.At Bentley University in Massachusetts, the number of new Chinese students arriving for graduate level work dropped from 110 last autumn to 70. As a result, Bentley officials are wondering whether all of its (Q9) graduate programs can survive."I wouldn't describe it as catastrophically bad," said the university's president, Alison Davis-Blake. She added that the university has tried to (Q10) get more students from other countries as well as from inside the United States.Large decreases in Chinese students also have been reported this autumn at the University of Vermont, which reported a 23 percent decrease. The University of Nebraska-Lincoln had a 20 percent decrease.China sends more students to study in the United States than any other country. Its 363,000 students represent more than (Q11) 30 percent of all international students at U.S. universities.Parents and students in China share concerns with those in other countries about (Q12) American gun violence as well as (Q13) immigration issues. In May, the group NAFSA: Association of International Educators identified two main reasons for falling numbers of international students who want to study in the United States: the difficulty of (Q14) getting a visa, and the (Q15) social and political environment in the United States.But there are also problems that affect only Chinese students. The Trump administration has accused China of stealing U.S. (Q16) intellectual property. It is looking very closely at Chinese students who ask for visas to study robotics, flight and high-tech manufacturing.In June, China warned students and other visitors to the United States about possible difficulties in (Q17) getting U.S. visas.Xiong Xiong is an electrical engineering student at Beijing Jiaotong University. He said he hopes to study at a U.S. university. But he is worried about the visa process, so he plans to ask to study in Britain. "I'm concerned my visa will be affected," he said.Brad Farnsworth is vice president for international global engagement at the American Council on Education. He said that his recent travels in China suggest the claims of economic espionage are making some students think they are not welcome."The concern is a Chinese student will be met with animosity about why they are in the United States," he said.International students add an estimated $39 billion to the U.S. economy.Normally, over 5,000 Chinese students are in the colleges of (Q18) engineering and business at the University of Illinois. The university recently took an insurance policy that will pay it $60 million if the money from Chinese students drops by 20 percent.Lehigh University in Pennsylvania announced this month it has agreed to pay a (Q19) recruiter to help bring in more students from India. It also has been taking more interest in African countries south of the Sahara Desert, said Lehigh's Cheryl Matherly.Like many other American universities, Lehigh has begun sending employees to Beijing and Shanghai to meet with Chinese students and their parents. The employees want to (Q20) ease Chinese fears about studying in the U.S. and show that their university wants Chinese students.I'm Jonathan Evans.

VOA慢速:智能手机数据或将拯救母亲和孩子生命燕山大学 刘立军 编写 TRANSCRIPTA new project in India and Uganda is aimed at helping health workers save the lives of mothers and babies with information from electronic devices.The $100 million project is funded by the Rockefeller Foundation, the World Health Organization, UNICEF, the World Bank and other groups. 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. The group is providing $60 million of the $100 million total cost. Shah said the plan is to give health workers low-cost tools to help them gather the information they need to help communities and families most at risk.The project will provide tools such as real-time risk maps to help health workers reach mothers and children. Workers also will be able to study non-health data on climate or social media patterns to predict and prepare for local disease outbreaks or health emergencies.Shah told Reuters, "A few years ago, these community health workers had no real technology, today the vast majority of them have smartphones with data and software technologies in their hands - and with those, we can help them do their work better."A U.N. report published last week stated that more women and newborn babies survive now than ever before. But, the report said that a baby or a pregnant woman still dies every 11 seconds somewhere in the world.Deaths of mothers are nearly 50 times higher for women in sub-Saharan Africa than in wealthy countries. The report also found that babies in Sub-Saharan Africa are 10 times more likely to die in their first month of life.I'm Jonathan Evans.Adapted from http://www.kekenet.com/broadcast/201909/595691.shtml VOCABULARY1. premature adj.

第九届教学大赛商务英语专业组一等奖褚凌云说课

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

第九届教学大赛商务英语专业组二等奖罗睿授课

授课点评:总体表现评价:罗睿老师口语流利,对所讲授内容比较熟悉,能够较好地回答提问评委的提问;对整个单元有一个粗略的教学目标、教学内容和教学方法设计,并且在授课过程有所体现;有教学方法(team-based learning),并能将此方法落实在具体授课中。但是,将教学目标分business level, language level 和ability level来概述,显得比较空洞。比如,business level的目标是“assess the business background”,language level是听说读写和语法,这些都是比较宽泛不具体的教学目标。具体表现评价:课堂组织比较有条理,给出的指令比较清晰;如视频2:30-2:50,能清晰地引导学生看具体哪一页的文本,并且告诉学生具体的教学流程有四部分构成,这样处理能让学生对接下来的授课安排有个总体认识。在授课过程,能针对所布置的任务进行个别指导,如视频中6:30-8:54,在布置完每一组(包括教师自己)的阅读任务后,能够逐一指导并和学生确认阅读任务。在视频4:06-5:00中使用“面子”视频,有新意,但插入该视频的时间节点有点突兀,和前后的授课内容逻辑上有点不顺;此外,未能充分利用好该视频,仅从视频中总结出什么是“面子”,但未能抓住视频中男孩没有脱鞋这个细节进行拓展。建议:授课语速和节奏可以适当放慢一些,从容一些。教学方法中提到案例教学法,但没有充分利用好D& G这个案例。如果能将这个案例作为课后讨论作业,让学生分析这个案例,讨论“面子”的重要性,则效果会更佳,也能真正体现案例教学法的效果。点评专家:郭桂航教授
