Unit1EconomicsText A:Lead-in:omittedCritical reading and thinking:Task1:Body:Use the labor and skills behind the Thanksgiving weekend as examples to illustrate the concept of“the invisible hand”End:Echo the beginning,emphasizing we should be grateful to the miracle on this Thanksgiving Day and every dayTask2:1.It is not difficult at all to explain why grocery stores stock up on turkey before Thanksgiving.There seemsto be no miracle in it.2.The use of so many“and’s”helps to emphasize that a series of actions and all kinds of work are involved inthe sale of Thanksgiving turkey.3.Here“from above”means“from God”.The phrase is used to show that there is something wondrous andalmost inexplicable in the social order of freedom.Task3:Market has its own way of punishing business malpractice.For example,if a fast food chain sells contaminated food,nation-wide demand for their food will go down,along with their profit.When a company sells defective products,they have to deal with liability costs.Language building-up:Task1:1．1．饲料经销商；饲料批发商2．为他自己的收益而工作3．技能与劳动力4．制造塑料5．私人交易6．包装并定价7．无形之手2．1.pricedbor3.transactions4.gainbor;manufactured6.the invisible hand7.distributorTask2:1.Today,in millions of homes across the nation,God will be thanked for many gifts,for the feast on thetable and the company of loved ones,for health and good fortune in the year gone by,for peace privilege of having been born—or having become—American.(Line2,Para.1)2.And yet,isn't there something wondrous—something almost inexplicable—in the way your Thanksgivingweekend is made possible by the skill and labor of vast numbers of total strangers?(Line1,Para.4)3.…Thanksgiving Turkey,there would be one—or more likely,a few dozen—waiting.(Line3,Para.6) Task3:1.very many2.buying or selling3.a large group of4.more huge5.understand6.troubledText B:Critical reading and thinking:Task1:1.Considering that her boyfriend doesn’t even bother to choose a gift for her,the girl concludes that hedoesn’t love her.Therefore,she breaks off the relationship.In the case where the strength of affection is most in question,people care a lot about what is given as a gift.2.The following is one more example where the signaling theory can be applied:In the job market,anemployer may not know whether a candidate is qualified for a post or not.Very often,the candidate will show the employer education credentials,which can be used as a signal to the employer.Thus the information gap is narrowed.Task2:(以下所有表格题若未说明，顺序皆为从上到下，从左到右)Internet browser;Windows operating system;deter;entering the market and offering new products;cars today include many built-in products;monopoly;80;reliable;easier to use;severely limited;changing;competitors;low;Researching:The U.S.economy is a free market economy with some government regulation ad there has been a lasting debate about how much government regulation is necessary.Those who argue for less regulation claim that the free market itself will require business to protect consumers and provide good products or services and the interference from the government can do nothing but increase the cost of doing corporations are not concerned about the public’s interest,so regulation is indispensable.Interestingly, Adam Smith himself believed that government had an important role to play in economic life.For example, he believed that the government should enforce contracts and grant patents and copyrights.Text C:Task:每一个精明的一家之主都知道，如果买一样东西所花的钱比在家里自己生产所花的成本要小，那就永远不要尝试在家里生产。

The author suggests that the rise of the internet and social media has made it easier for non-English speakers to promote their languages and cultures.5. The author predicts that, as the number of English speakers decreases in proportion to non-English speakers, the dominance of English may decline.6. The author concludes that while English will likely remain an important language, it may no longer hold the same level of dominance in the future.Unit 2: Grammar and WritingPart A: Grammar1.

The dog, which had been lost for days, was finally found by its owner.4. The book, which was written by a famous author, was highly recommended by my teacher.5. The movie, which received rave reviews, won several awards at the film festival.Part B: WritingThe Impact of Technology on EducationTechnology has revolutionized the field of education, transforming the way students learn and teachers teach. From online learning platforms to interactive educational tools, technological advancements have opened up new possibilities in education.One significant impact of technology in education is the accessibility of information. With the internet, students now have access to a vast amount of knowledge at their fingertips. They can easily research and find information on any topic, enabling them to deepen their understanding and broaden their horizons. This accessibility of information has empowered students to take control of their own learning and pursue knowledge beyond the confines of the traditional classroom.Furthermore, technology has enhanced communication and collaboration in education. Online platforms, such as discussion forums and video conferencing tools, enable students to engage in virtual discussions and group projects. This enables students to connect with peers from different backgrounds and locations, facilitating the exchange of ideas and perspectives. Additionally, teachers can provide feedback and support to students in real-time through online platforms, promoting a more interactive and personalized learning experience.In addition to accessibility and communication, technology has also made learning more engaging and interactive. Interactive educational tools, such as virtual reality simulations and gamified learning platforms, can create immersive learning experiences that capture students' attention and foster active participation. These tools allow students to learn through hands-on experiences and experimentation, making the learning process more enjoyable and effective.However, it is important to acknowledge that technology in education also presents challenges. The digital divide, for example, refers to the unequal access to technology among different socio-economic groups. This disparity can hinder some students from fully benefiting from technological advancements in education. Moreover, concerns about privacy and online safety need to be addressed to ensure that students can learn in a secure and protected environment.In conclusion, technology has had a profound impact on education, revolutionizing the way students learn and teachers teach. It has made information more accessible, enhanced communication and collaboration, and made learning more engaging and interactive. While challenges exist, the potential of technology in education is immense, and it is crucial to continue exploring innovative ways to integrate technology into the classroom for the benefit of students worldwide.。

Unit11、Some factors that may lead to the complaint:·Neuron overload·Patients* high expectations·Mistrust and misunderstanding between the patient and the doctor2、Mrs. Osorio’s condition:·A 56-year-old woman·Somewhat overweight·Reasonably well-controlled diabetes and hypertension·Cholesterol on the high side without any medications for it·Not enough exercises she should take·Her bones a little thin on her last DEXA scan3、Good things:·Blood tests done·Glucose a little better·Her blood pressure a little better but not so great Bad things:·Cholesterol not so great·Her weight a little up·Her bones a little thin on her last DEXA scan 44、The situation:·The author was in a moderate state of panic: juggling so many thoughts aboutMrs. Osorio’s conditions and trying to resolve them all before the clock ran down.·Mrs. Osorio made a trivial request, not so important as compared to her conditions.and completely justified ·Mrs. Osorio seemed to care only about her “innocent —：the form signed by her doctor.—request”·The doctor tried to or at least pretended to pay attention to the patient whilecompleting documentation.5、Similarities:·In computer multitasking, a microprocessor actually performs only one task at a time. Like microprocessors, we human beings carft actually concentrate on two thoughts at the same exact time. Multitasking is just an illusion both in computersand human beings.Differences:·The concept of multitasking originated in computer science.·At best, human beings can juggle only a handful of thoughts in a multitasking manner, but computers can do much better.·The more thoughts human beings juggle, the less human beings are able to attune fully to any given thought, but computers can do much better.6、·7 medical issues to consider·5 separate thoughts, at least, for each issue·7 x 5 = 35 thoughts·10 patients that afternoon·35 x 10 = 350 thoughts·5 residents under the authors supervision·4 patients seen by each resident·10 thoughts, at least, generated from each patient·5 x 4 x 10 = anther 200 thoughts·350 + 200 = 550 thoughts to be handled in total·If the doctor does a good job juggling 98% of the time, that still leaves about 10 thoughts that might get lost in the process.7、Possible solutions:·Computer-generated reminders·Case managers·Ancillary services·The simplest solution: timeUnit21、The author implies:? Peoples inadequate consciousness about the consequence of neglecting the re-emerging infectious diseases·Unjustifiability of peoples complacency about the prevention and control of theinfectious diseases·Unfinished war against infectious diseases2、Victory declarations:·Surgeon General William Stewart's hyperbolic statement of closing “the book on infectious disease”.·A string of impressive victories incurred by antibiotics and vaccines·The thought that the war against infectious diseases was almost overWhat followed ever since:·Appearance of new diseases such as AIDS and Ebola·Comeback of the old afflictions:? Diphtheria in the former Soviet Union? TB in urban centers like New York City? Rising Group A streptococcal conditions like scarlet fever·The fear of a powerful new flu strain sweeping the world3、Elaborate on the joined battle:·WHO established a new division devoted to worldwide surveillance and controlof emerging disease in October 1995.·CDC launched a prevention strategy in 1994.·Congress raised fund from $6.7 million in 1995 to $26 million in 1997.4、The borders are meaningless to pathogenic microbes, which can travel fromone country to another remote country in a very short time.5、TB:·Prisons and homeless shelters as ideal places for TB spread·Emerging of drug-resistant strain or even multi-drug-resistant strain·A ride on the HIV w^on by attacking the immunocompromisedGroup A strep:·A change in virulence·Mutation in the exterior of the bacteriumFlu:Constant changes in its coat (surface antigens) and resultant changes in its levelof virulence6、Examples:·Experiment in England is seeing the waning immunity because of no vaccination. ·Du e to poor vaccination efforts, the diphtheria situation in the former Soviet Union is serious. '? The vaccination rates are dropping in some American cities, and it will lead to more diphtheria and whooping cough.7、The four areas of focus:·The need for surveillance·Updated science capable of dealing with discoveries in the field·Appropriate prevention and control·Strong public health infrastructure8、The infectious diseases such as TB, flu, diphtheria and scarlet fever will never really go away, and the war against them will never end.Unit31、Terry's life before·She loved practicing Tae Kwon Do·She loved the surge of adrenaline that came with the controlled combat of tournaments.·She competed nationally, even won bronze medal in the trials for the Pan American Games.·She attended medical school, practiced as an internal medicine resident, and became an academic general internist.·She got married and got a son and a daughter.2、The symptoms of MS and autoimmune disease:·Loss of stamina and strength·Problems with balance·Bouts of horrific facial pain·Dips in visual acuity3、Terry did the following before she self-experimented:·She started injections.·She adopted many pharmacotherapies.·She began her own study of literature:? She read articles on websites such as PubMed.? She searched for articles testing new MS drugs in animal models.? She turned to articles concerning neurodegeneration of all types — dementia，Parkinson's disease, Huntington's disease, and Lou Gehrig's disease.? She relearned basic sciences such as cellular physiology, biochemistry, andneurophysiology.4、Approaches Terry mainly used:·Self-experimentation with various nutrients to slow neurodegeneration based on literature reports on animal models·Self-experimentation with neuromuscular electrical stimulation which is not an approved treatment for MS·Online search to identify the sources of micronutrients and having a new diet ·Reduction of food allergies and toxic load5、Cases mentioned in the text:·Increased mercury stores in the brains of people with dental fillings·High levels of the herbicide atrazine in private wells in Iowa·The strong association between pesticide exposure and neurodegeneration·The association of single nucleotide polymorphisms involving metabolism of sulfur and/or B vitamins·Inefficient clearing of toxins6、With 70% to 90% of the risk for diabetes, heart disease, cancer, andautoimmunity being due to environmental factors other than the genes, we cantake many health problems and the health care crisis under our control, for example, optimizing our nutrition and reducing our toxic load.Unit41、Two concepts:·Complementary medicine refers to the use of conventional therapies together with alternative treatments such as using acupuncture in addition to usual care to help lessen pain. Complementary and alternative medicine is shortened as CAM.·Alternative medicine refers to healing treatments that are not part of conventional therapies —like acupuncture, massage therapy, or herbal medicine. They are called so because people used to consider practices like these outside the mainstream.2·TCM does not require advanced, complicated, and in most cases, expensivefacilities.·TCM employs needles, cups, coins, to mention but a few.·Most procedures and operations of TCM are noninvasive.·The substances used as medicine are raw herbs or abstracts from them, andthey are indeed all natural, from nature.·TCM has been practiced as long as the Chinese history, so the efficiency i s proven and ensured.·Ongoing research around the world on acupuncture, herbs, massage and Tai Chi have shed light on some of the theories and practices of TCM3、It may be used as an adjunct treatment, an alternative, or part of a comprehensive management program for a number of conditions: post-operativeand chemotherapy induced nausea and vomiting, post-operative dental pain, addiction, stroke rehabilitation, headache, menstrual cramps, tennis elbow, fibromyalgia, myofascial pain, osteoarthritis, low back pain, carpal tunnel syndrome, and asthma.4、A well-justified NO:·More intense research to uncover additional areas for the use of acupuncture ·Higher adoption of acupuncture as a common therapeutic modality not only in treatment but also in prevention of disease and promotion of wellness·Exploration and perfection of innovative methods of acupuncture point stimulation with technological advancement·Improved understanding of neuroscience and other aspects of human physiology and function by basic research on acupuncture·Greater interest by stakeholders·An increasing number of physician acupuncturists5、·Appropriate uses of herbs depend on proper guidance:? Proper TCM diagnosis of the zheng of the patient?Correct selection of the corresponding therapeutic strategies and principles that guide the choice of herbs and herbal formulas·Digression from either of the above guidence will lead to misuses of herbs, andwill result in complications in patient6、·Randomized controlled trialsAdvantages:?Elimination of the potential bias in the allocation of participants to the intervention group or control group? Tendency to produce comparable groups? Guaranteed validity of statistical tests of significanceLimitations:? Difficulty in generalizing the results obtained from the selected sampling to the population as a whole? A poor choice for research where temporal factors are anissue?Extremely heavy resources, requiring very large samplegroups? Quasi-experimentsAdvantages:? Control group comparisons possible?Reduced threats to external validity as natural environments do notsuffer the same problems of artificiality as compared to a well-controlledlaboratory setting.?Generalizations of the findings to be made about population since quasiexperiments are natural experimentsLimitations：? Potential for non-equivalent groups as quasi-experimental designs donot use random sampling in constructing experimental and controlgroups.?Potential for low internal validity as a result of not using random sampling methods to construct the experimental and control groups? Cohort studiesAdvantages:?Clear indication of the temporal sequence between exposure and outcome? Particular use for evaluating the effects of rare or unusual exposure? Ability to examine multiple outcomes of a single risk factorLimitations:? Larger, longer, and more expensive? Prone to certain types of bias? Not practical for rare outcomes? Case-control studiesAdvantages:? The only feasible method in the case of rare diseases and those with longperiods between exposure and outcome? Time and cost effective with relatively fewer subjects as compared to other observational methodsLimitations：? Unable to provide the same level of evidence as randomized controlled trialsas it is observational in nature? Difficult to establish the timeline of exposure to disease outcometrials? “N=1”Advantages? Easy to manage? InexpensiveLimitations：? Findings difficult to be generalized to the whole population? Weakest evidence due to the number of the subject7、? Synthesis of evidence is completely dependent on:? The completeness of the literature search (unavailable for foreign studies)? The accuracy of evaluation·There are situations in which no answer can be found for the questions of interest in RCTs and database analyses.·There's the requirement of using less stringent information rather than “hard data”8、·Assessment of the intrinsic value of traditional medicine in society·Research and education·Political, economic, and social factorsUnit51、·Dis-ease refers to the imbalance arising from：? Continuous stress? Pain? Hardships·Disease is a health crisis ascribable to various dis-eases.·Prompting elimination of dis-eases can alleviate some diseases.2、·Wellness is a state involving every aspect of our being: body, mind and spirit.·Manifestations of a healthy person:?

Lesson 1Question:1. Why did John Koshak decide to stay although he knew the hurricane would be bad? For the following reasons: For one thing, the house was 23 feet above sea level; for another,he was unwilling to abandon his home.2. How did the man prepare for the hurricane? Why was a generator necessary? They filled bathtubs and pails. Besides, they checked out batteries for portable radio and flashlights, and fuel for the lantern. A generator was necessary because John's father wired several light bulbs to it and prepared a connection to the refrigerator.3. What made it impossible for the Koshak to escape?It was impossible for the Koshers to escape both by car and on foot. The car's electrical system had been killed by water. Meanwhile, the water became too deep for them to escape on foot.4. Why did John Koshak feel a crushing guilt?Because he blamed himself for underestimating the power of the hurricane and then endangering the whole family by his wrong decision not to flee safer inland.5. Why did Grandma Koshak ask children to be sing?A: Because she knew how frightened the children were and wanted to boost their spirit.6. What was a hurricane party? What happened to the party gores?A hurricane party was the one that was held by several vacationers to enjoy the spectacle of the hurricane with a clear and broad view in the fancy Richelieu Apartments from where they believed they would be safe. Richelieu Apartments were smashed apart by the hurricane and 26 people perished.7. What did Grandma Koshak mean when she said," We lost practically all our possessions, but the family came through it. When I think of that, I realize we lost nothing important?"She meant that human lives are more important than material possessions.8. How did the community of Gulfport act after Hurricane Camille was over?They managed to make their lives return to normal and began rebuilding their community without any delay.Paraphrase:1. We're elevated 23 feet.Our house is 23 feet above sea level.2. The place has been here since 1915, and no hurricane has ever bothered it. The house was built in 1915 and since then no hurricane has done any damage to it.3. We can batten down and ride it out.We can prepare ourselves for the hurricane and manage to survive it without much damage.4. The generator was doused, and the lights went out.Water got into the generator, and it didn't work. As a result, the lights were put out.5. Everybody out the back door to the cars!Everybody go out though the back door and get into the cars.6. The electrical system had been killed by water.The electrical system in the cars had been destroyed by water.7. John watched the water lap at the steps, and felt a crushing guilt.When John watched the water inch its way up the steps, he felt a strong sense o f guilt because he blamed himself for understanding the ferocity of Camille and endangering the whole family by making the wrong decision not flee inland. 8. Get us through this mess, will you?Oh, god! Please help us to get through the danger situation.9. She carried on alone for a few bars, then her voice trailed away.She sang a few words alone and then her voice gradually grew dimmer and stopped .10. Janis had just one delayed reaction.Janis didn't show her fear on the spot during the hurricane, but she revealed h er emotions caused by the hurricane several nights after the hurricane by getti ng up in the middle of the night, going outside and crying softly.翻译：1. But, like thousands of others in the coastal communities, John was reluctant to abandon his home unless the family---his wife, Janis, and their seven children, aged 3 to 11--- was clearly endangered. 但是，和沿海地区其他成千上万的人一样，约翰不愿舍弃自己的家园，除非他的家人—自己的家人贾妮斯以及他们的7个孩子，大的11岁，小的才3岁—明显处于危险之中。

Teaching Procedures1.Deciding on a topicTask 1Answers may vary.Task 21 No, because they all seem like a subject rather than a topic, a subject which cannot be addressed even by a whole book, let alone by a1500-wordessay.2Each of them can be broken down into various and more specific aspects. For example, cancer can be classified into breast cancer, lung cancer, liver cancer and so on. Breast cancer can have such specific topics for research as causes for breast cancer, effects of breast cancer and prevention or diagnosis of breast cancer.3 Actually the topics of each field are endless. Take breast cancer for example, we can have the topics like:Why Women Suffer from Breast Cancer More Than Men?A New Way to Find Breast TumorsSome Risks of Getting Breast Cancer in Daily LifeBreast Cancer and Its Direct Biological ImpactBreast Cancer—the Symptoms & DiagnosisBreastfeeding and Breast CancerTask 31 Text 1 illustrates how hackers or unauthorized users use one way or another to get inside a computer, while Text2 describes the various electronic threats a computer may face.2 Both focus on the vulnerability of a computer.3 Text 1 analyzes the ways of computer hackers, while Text 2 describes security problems of a computer.4 Text 1: The way hackers “get inside” a computerText 2: Electronic threats a computer facesYes, I think they are interesting, important, manageable and adequate.Task 41Lecture1:Ten Commandments of Computer EthicsLecture 2:How to Deal with Computer HackersLecture 3:How I Begin to Develop Computer Applications2Answersmay vary.Task 5Answers may vary.2 Formulating a research questionTask 1Text 3Research question 1: How many types of cloud services are there and what are they?
