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 about Mrs. 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.·Mrs. Osorio seemed to care only about her “innocent —and completely justified —request”：the form signed by her doctor.·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 computers and 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 the infectious 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 control of 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 from one 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 level of 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, and neurophysiology.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 can take 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, expensive facilities.·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, and they 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-operative and 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, and will 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 long periods 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 trials as it is observational in nature» Difficult to establish the timeline of exposure to disease outcome• “N=1” trialsAdvantages» 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:» Energy and vitality» A certain zip in gait» A warm feeling of peace of heart seen through behavior3、·Constant messages, positive and negative，are sent to our mind about the health of our body.·Physical symptoms are suppressed by people who go through life on automatic pilot.·Being well equals to being disease- or illness-free in the minds of them.·They confused wellness with an absence of symptoms.4、·People's minds are infected by spin:» Half-truth» Fearful fictions» Blatant deceit: some as a form of self-deceit·Spin is a result of unconscious living.·The kind of falseness is pandemic.5·Our body intelligence is suppressed or dormant from a lack of use.·There are tremendous amount of stress on a daily basis.·Our bodies are easily ignored for years because of a lack of recreation time. ·Limiting, self-defeating and even self-destructive behaviors undermine our wellbeing and keep them from achieving our full potential.6·We grow more reluctant to take risks.·We lose the ability to feel and acknowledge our deepest feelings and the courage to speak our truth.·We continue to deny and repress our feelings to protect ourselves.·Fear, denial and disconnection from our bodies and feelings become an unconscious, self-protective habit, a kind of default response to life.7·A multi-faceted process:» Looking for roots of and resolutions for the issues in different dimensions» Building our wellness toolbox slowly» Picturing our whole state of being·Attention to the little stuff:» Examining our lives honestly and setting clear intentions to change» Striving to maintain a balance of our mind, body and spirit» Taking small steps in the way to perceive and resolve conflict8·Try to awaken and evolve in order to live more consciously.·Get in touch with our genuine feelings and emotions.·Come to terms with the toxic emotions1、In the past, most people died at home. But now, more and more people are caredin hospitals and nursing homes at their end of life, which of course brings a new set of questions to consider.2、·Sixty-four years old with a history of congestive heart failure·Deciding to do everything medically possible to extend his life·Availability of around-the-clock medical services and a full range of treatment choices, tests, and other medical care·Relaxed visiting hours, and personal items from home3、Availability of around-the-clock medical resources, including doctors, nurses, andfacility.4、·Taking on a job which is big physically, emotionally, and financially·Hiring a home nurse for additional help·Arranging for services (such as visiting nurses) and special equipment (like a hospital bed or bedside commode)5、·Health insurance·Planning by a professional, such as a hospital discharge plaimer or a social worker·Help from local governmental agencies·Doctor's supervision at home6、·Traditionally, it is only about symptom care.·Recently, it is a comprehensive approach to improving the quality of life for people who are living with potentially fatal diseases.·Stopping treatment specifically aimed at curing an illness equals discontinuing all treatment.·Choosing a hospice is a permanent decision.Unit71、·A dying patient·Decision whether to withdraw life-support machines and medication and start comfort measures·The family's refusal to make any decision or withdraw any treatments2、·The doctor as exclusive decision-maker·The patient as participant with little say in the final choice3、·Respect for the patient, especially the patient s autonomy·Patient-centered care·The patient as decision-maker based on the information provided by the doctor 4、·Patients are forced to make decisions they never want to.·Patients, at least a large majority of them, prefer their doctors to make final decisions.·Shifting responsibility of decision-making to patients will bring about more stress to patients and their families, especially when the best option for the patient is uncertain.5、Doctors are very much cautious about committing some kind of ethicaltransgression.6、·Shouldering responsibility together with the patient may be better than having the patient make decisions on their own.·Balancing between paternalism and respect for patients autonomy constitutes a large part of medical practice.Unit81、·Research:An activity to test hypothesis, to permit conclusions to be drawn, and thereby to develop or contribute to generalizable knowledge·Practice:Interventions solely to enhance the well-being of an individual patient or client and that have a reasonable expectation of success·Blurred distinction:» Cooccurrence of research and practice like in research designed to evaluate a therapy» Notable departures from standard practice being called “experimental” with the terms “experimenta l”and “research” carelessly defined2、·Autonomy：Individuals treated as autonomous agents .·Protection:Persons with diminished autonomy entitled to protection·A case in point:Prisoners involved in research3·“Do no harm” as the primary principle·Maximization of possible benefits and minimization of possible harms . ·Balance between benefits and potential risks involved in every step of seeding the benefits4、·“Do no harm” as a fundamental principle of medical ethics·Extension of it to the realm of research by Claude Bernard·Benefits and risks as a set “duet” in both medical practice and research5、·Unreasonable denial of entitled benefit and unduly imposed burden：Enrolment of patients in new drug trial: Who should be enrolled and who should not?·Equal treatment of equals:Determining factors of equality: age, sex, severity of the condition, financial status, social status6、·Definition:The opportunity to choose what shall or shall not happen to them ·Application:» A process rather than signing a written form» Adequate information as the premise» A well-informed decision as the expected result7、·Requirements for consent as entailed by the principle of respect for persons ·Risk/benefit assessment as entailed by the principle of beneficence·More requirements of fairness as entailed by the principle of justice: » At the individual level: fairness» At the social level: distinction between classes。

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。

(完整版)学术英语(医学)课后问题答案
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:? Energy and vitality? A certain zip in gait? A warm feeling of peace of heart seen through behavior3、·Constant messages, positive and negative，are sent to our mind about the health of our body.·Physical symptoms are suppressed by people who go through life on automatic pilot.·Being well equals to being disease- or illness-free in the minds of them.·They confused wellness with an absence of symptoms.4、·People's minds are infected by spin:? Half-truth? Fearful fictions? Blatant deceit: some as a form of self-deceit·Spin is a result of unconscious living.·The kind of falseness is pandemic.5·Our body intelligence is suppressed or dormant from a lack of use.·There are tremendous amount of stress on a daily basis.·Our bodies are easily ignored for years because of a lack of recreation time. ·Limiting, self-defeating and even self-destructive behaviors undermine our wellbeing and keep them from achieving our full potential.6·We grow more reluctant to take risks.·We lose the ability to feel and acknowledge our deepest feelings and the courage to speak our truth.·We continue to deny and repress our feelings to protect ourselves.·Fear, denial and disconnection from our bodies and feelings become an unconscious, self-protective habit, a kind of default response to life.7·A multi-faceted process:? Looking for roots of and resolutions for the issues in different dimensions? Building our wellness toolbox slowly? Picturing our whole state of being·Attention to the little stuff:?

Teaching Procedureson 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 toget inside a computer, while Text 2 describes the various electronic threats acomputer may face.2 Both focus on the vulnerability of a computer.3 Text 1 analyzes the ways of computer hackers, while Text 2 describes securityproblems 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?Research question 2: What is green computing?Research question 3: What are advantages of the cloud computing?Text 4Research question 1: What is the Web ?Research question 2: What are advantages and disadvantages of the cloud computing?

Teaching Procedures1 Finding reliable and better sourcesTask 1Answers may vary.Task 2Answers may vary.Task 3Answers may vary.2 Scanning and skimmingTask 11 Artificial intelligence.2 The article may argue for/against the idea that artificial intelligence will replace human jobs in the future.3 The story tells that computerization threatens to replace many white-collar jobs.4 The author is optimistic and may not agree that machines will replace human jobs.5 The specter of automation unemploying us all may have finally arrived.6 But the mass job shrinkage that these observers all expected did not come.7 Yet Americans as a whole were not automated out of work. (Para.8, L1)Yet, through all that, more new jobs appeared. (Para.11, L2)8 Man will not lose jobs because there will always be demands of a new economy.9 The neighbor would prefer to order the shoes from machine-handling factories.10 Saving will lead to spending which in turn will create newer, perhaps better jobs tomorrow.3 Identifying topic sentences for informationTask 11 Pieced together, the topic sentences form a short, coherent paragraph or essay.2 a) Paragraph 2b) Paragraph 11Task 21 Game theory is the science of strategy.（Para.1）2 Games are fundamentally different from decisions made in a neutral environment.（Para.3）3 The essence of a game is the interdependence of player strategies.（Para.4）4 A general principle for a player in a sequential-move game is to look ahead and reason back. （Para.5）5 In contrast to the linear chain of reasoning for sequential games, a game with simultaneous moves involves a logical circle.（Para.7）6 Another way to make threats credible is to employ the adventuresome strategy of brinkmanship—deliberately creating a risk that if other players fail to act as one would like them to, the outcome will be bad for everyone.（Para.17）Task 31 Paragraph 12 Paragraph 5 to 103 Paragraph 12 to 194 Guessing word meaningTask 12 immutable (Para.4, L2): 不变的Context clues: who realized that space is not an immutable stage on which events play out3 trampoline (Para.4, L4): 蹦床，弹床Context clues: responding much as a trampoline does to a jumping child4 malleable (Para.4, L5): 有弹性和延伸性的Context clues: In fact, so malleable is space that, according to the math, the size of the universe necessarily change over time.5 stay put (Para.4, L7): 不动的Context clues: The fabric of space must expand or contact—it can’t stay put.6 flew in the face (Para.5, L4): 敢于违抗Context clues: It flew in the face of the prevailing wisdom.7 stalemate (Para.6, L2): 僵局Context clues: A static situation, like a stalemate in a tug of war8 repulsive (Para.6, L5): 排斥的Context clues: a counterbalancing force would need to provide a repulsive push9 antigravity (Para.7, L2): 排斥力Context clues: antigravity—a gravitational force that pushes instead of pulls10 exodus (Para.8, L3): 大批离开Context clues: And the best explanation for this cosmic exodus came directly.11 supernovae (Para.11, L2): 由于爆炸而突然变亮的星Context clues: distant supernovae—exploding stars so brilliant they can be seen clear acrosscosmos12 garner (Para.13, L5): 获得、得到Context clues: would have garnered him another Nobel Prize13 perplexing (Para.14, L5): 令人不解的Context clues: Perhaps most perplexing of all is a question of quantitative detail.Task 22 unprecedented (Para.1, L1): un-precedented 史无前例的3 self-replicating (Para.1, L6): self-replicating 自我复制的4 diameter (Para.3, L2): dia-meter 直径5 assembler (Para.10, L1): assembl-er 装配器6 contaminant (Para.13, L3): con-taminant 污染物7 non-renewable (Para.13, L6): non-renewable 不可再用的8 foreseeable (Para.14, L2): foresee-able 可预见到的9 exotic (Para.14, L2): exot-ic 非本地，奇异的10 dissipate (Para.14, L6): dis-sipate 消失Task 3Derivatives Affixes or roots Meaning More Words1 multidiscipline multi- many or several Multicolor multistepsmultiform multipurpose2 nanotechnology nano-one of a thousandmillion nanorobot nanomachine nanoscopic nanostructure3 convergence vergcon-incline tojoindivergence vergeconcordconcourse conferate4 construct struct build or make structure reconstructdestruct obstructsubstructure5 manufacture man-,manu-fact by handmakemanuscript manualmanage manipulatefactory facture6 interdisciplinary inter-between or among agroup of things or people interplay interweave interdependent interaction7 insulator insul-protect sth. from insulate insular insularityunpleasant knowledge peninsula8 semiconductor semi-duct- partly but not completelyleadsemiconscious semiofficialsemitropical conductinduct9 microprocessors micro-extremely small microwavemicrocomputermicroscope micrometer 10 simultaneouosly simul-in common simulator simulationsimultaneity simulate11 reverse vers,vert turn obversion inversesubversion convert12 automatical auto Work by oneself;relating to oneself automate autonomous automobile autobiography5 Using the organization of the textTask 1organization paragraphs Introduction Para.1What The definition ofnanotechnology nanotechnology Para.2 nanometer Para.3 nanoscale Para.4How The waynanotechnology worksParas.5-11How The applications ofnanotechnologymedical industry Para.12environment Para.13other fields Para.14 conclusion Para.15Task 21 The writer develops his main ideas about global warming mainly through the structure of cause-and-effect.2 The writer illustrates the effects of global warming through the structure of classification.3 The effects are arranged from the most obvious to least obvious, and signal words include: themost prominent effect of global warming; another area affected by global warming; a third type of evidence of global warming.4 Four types. They are carbon dioxide, methane, nitrous oxide and chlorofluocarbons.5 Paragraph 11 follows the pattern of problem-and-solution. The signal words are “a common problem that arises is”, “needs to take action now”.6 Reading criticallyTask 1The tone of one’s writing indicates their feelings and attitude toward the topic being discussed. It reveals whether they are being playful or serious, humorous or somber, whether they are angry or tranquil, bitter or confident. Through tone, their attitude toward what they are writing about and their relationship to their readers become clear.Controlling tone is largely a matter of selecting words and sentences, and choosing details so as to serve the purpose of writing well. Now let’s consider the following sentences which you write to tell two facts:The sales of vitamin E have doubled in the past five years. The increase in sales has been helped by the statements from health food enthusiasts and doctors.1 Combined into a single one, sentence 1 is impartial in tone because it doesn’t reveal your attitude. Impartial and toneless sentences are what you want to write if you either have no opinion or want to seem factual and objective, rather than personal and subjective.2 Strong in tone and clear in attitude: sentence 2 reflects your belief that vitamin E sales have surged because of a deceptive and misleading advertisement campaign. If you feel the sentence is too strong, too opinionated, perhaps even biased, you may suggest your feelings instead of stating them directly.3 By using the words—freaks and quack, this version can make your reader sense not only your reservation about the worth of the vitamin but also your contempt of those who promote it. But the tone is so strong that your reader may consider it exaggerated and may even question its truth.4 This version is more suggestive and less explicit, though your attitude is still negative because “faddists” (unlike enthusiasts) are a word with unfavorable associations and because claims “(unlike statements)” encourage the reader to doubt their truth.5 By inserting the detail that only a few doctors make claims for vitamin, the version seems biased as the tone is stronger.6 The phrase “some doctors” implies that there is another group of doctors who have made no claims for the vitamin and who may perhaps reject such claims.7 Th e word “even” suggests your surprise that doctors, who should know better, have made such foolish claims, thus further weakens the support of the doctors without making your statement seem exaggerated or biased.8, 9 Tone not only can be controlled by the choice of words and details but also by the choice of structures. Sentence 8 and 9 make the implied criticism more forceful as the negative words or phrases have been moved to their beginning or end position, the position which is more emphatic for one’s opinion.10, 11, 12 The three sentences are not critical but favorable in tone toward the increased sales ofvitamin E, because “experts” seem more trustworthy than “enthusiasts” and both “reports” and “testimony” carry more weight than mere “statements”.13, 14 The two sentences have a positive tone because the phrase “a number of doctors” sounds more impressive than “a few” or “some doctors”. And “a number of leading doctors” are supposed to be more reliable, though not as reliable as “leading medical authorities”.15, 16, 17 The three sentences are less formal and more personal than the previous sentences as the first-person view “I” is adopted to personalize their tone.18, 19 The two sentences are more informal as the closer relationship between yourself and the reader is established by asking questions.20, 21 By addressing the reader as “you”, the sentences are more informal and personal.22 The informality of your writing will be increased by contractions, slang, and short, simple words instead of longer, more complex ones.Task 21 Text 9 addresses readers with some knowledge of global warming, because the author argues with strong evidence and reasons, quoting experts more frequently and trying to be impartial and impersonal by choosing more exact wording. On the contrary Text 10 talks to general readers, evidenced by using more definitions and easier language such as figurative speech. It is an essay charged with strong emotion.2 Text 10.3 No. Text 9 illustrates the effects of global warming with strong evidence and reasons, showing that the author tries to be objective and impersonal.4 No. These words lack preciseness. Text 9 tries to be more objective, quoting experts more frequently and avoiding showing strong personal emotion.5 Text 9 quotes Roger Revelle, an oceanographer, Jacques Chirac, French president, Al Gore, Vice president of USA, Ross Gelbspan, an author of a book about Earth’s climate change from global warming, Schneider, from the National Center of Atmospheric Research, and Elmer Robinson, the director of Mauna Loa Observatory. The quotation of those experts and authorities make the arguments more convincing.6 The criticism of Text 9 avoids being subjective and personal and resorts to more authorities and cold reasoning, hence it is more objective.7 Text 9. The use of the first-person view and figurative speech is often considered informal and less serious.8 Text 9, because the author uses more quotations from experts and authorities and less emotional words than Text 10.7 Taking notesTaskTitle: Global Warming and Its EffectsAuthor(s): Nicolas DallevaSource: Main ideas: The essay mainly talks about the effects and causes of global warming.Main findings or ideas: Global warming have negative effects on climate changes, survival of animals, development of plants, people’s health and global economy. There are two major causes for global warming: burning of fossil fuels and greenhouse gases.8 Writing a summaryTask 1The source material uses a story of identical twins to illustrate the idea that apart from the important role the genes play in the development of an individual, their environmental experience also affects their traits greatly. The summary grasps the idea without details of the story.Task 22 History has demonstrated that technology affects education profoundly. Considering the definition of technology broadly, one may say that prehistoric people used primitive technologies to teach skills to their young.3 Psychology can be divided into several important theories. Behaviourists emphasize the role of environment in shaping one’s behavior, while cognitivists explain behavior by analyzing mental processes. Freudians and humanists are more concerned with exploring behavior through the personality whereas social constructivists connect individual behavior to its social-historic context.Task 3Title: Global Warming and Its EffectsAuthor(s): Nicolas DallevaSource: Summary: According to Nicolas Dalleva, global warming has become a great challenge to human beings, for it not only affects the climate change and leads to the decrease of the number of animals per species, but also affects the agricultural growth. Dalleva believes that the burning offossil fuels is the culprit of global warming because it releases greenhouse gases carbon dioxide into the atmosphere. The other gases like methane, nitrous oxide and chlorofluocarbons are also the causes of the greenhouse effect. In Dalleva’s opinion, despite the worldwide efforts, people do not take the issue seriously and do not realize that global warming will also exerts a negative effect on economy and health. He calls for, therefore, a stronger joint effort to prevent global warming. (134 words)Task 4Lecture 6Since the industrial revolution, people’s private sphere have been separated from their working places. Institutions like offices, factories and schools impose isolation on people who are blocked to their privacy sphere at work or at school. Now people try to break the isolation and seek intimacy with high-tech communication tools like facebook, skype, cell phones and emails. The tools enable people to gain comfort and warmth from close friends or families. (72 words) Lecture 7The Kepler Mission is to search for planets by measuring the starlight, through which we can learn about how stars and planets interact to form their eco-system and whether there exist life in other planets or whether they are suitable for life living. In over two years of its operations, over 1,200 potential new planetary systems have been found around other stars. Apart from that, the Kapler also tries to find the size of a planet and how the distance from its parent star. It also observes the effects of our sun’s magnetic activity. (94 words)Lecture 8Traditionally, doctors treat cancers by attacking individual cells. By identifying separate forms cancer cells without molecule test or gene sequencing, however, we can’t understand how the whole cancer system works. Thus the effect of this method is very limited. After exchanging thoughts with Danny, the speaker came up with a new strategy. That is the combination of atypical drugs, computer modeling and protein analysis. It may become one of the most effective ways to treat cancers. (76 words)Lecture 9Mammography is the most common way to detect breast cancer. However, with the increase of breast density, it would be harder to find cancer through X-ray. Dr. Deborah Rhodes has developed a new tool for tumor detection, which is three times as effective as traditional mammograms. What’s more, it is cheaper than other technology. But her research was rejected for by jo urnals, because it is so cheap that the producers of traditional mammograms won’t be happy to see it. Furthermore, there are also some political forces keeping it from the market.

Unit 4 Writing a Literature ReviewI. Teaching ObjectivesIn this unit, you will learn how to:1.write a self-contained literature review2.write a literature review as a part of an essay3.cite sources by correct quotation and paragraphs4.give the appropriate documentation to the source you use5.avoid different kinds of plagiarism6.identify common knowledge7.acquire paraphrasing skills8.enhance language skills related with reading and listening material presented in this unit II. Teaching Procedures1 Writing a literature reviewTask 11 The four articles were published right after the Fukushima disaster in Japan and all addressed the topic of potential risks of nuclear radiation.2 Radiation is not so terrible as expected and human beings are exposed to different sources of radiation every day. Whether it will endanger human health or not depends on the duration and strength of radiation exposure.3 Amber Cornelio holds a different attitude from the other three authors. He believes that radiation exposure will certainly raise the risk of getting cancer and government officials downplay its potential danger to justify its use of nuclear power.4 Answers may vary.5 It seems that Text 11, 12, 14 provide more scientific facts about nuclear radiation than Text 13 which is more emotionally charged by using many rhetorical questions and phrases like “I am simply floored”, “let officials be oblivious”, “not to be outdone”, “Do not tell us about that”. Hence it appears less reliable and trustworthy.Task 2Compared with uranium which the production of conventional nuclear power needs, there is more lithium in the sea water which can support 30 million years’ fusion fuel.Task 31 Review the previous related studies2 State the previous s tudies’ limitation3 Announce the direction for further studies2 Writing a self-contained literature reviewTask 11 Stigmatization, a kind of social rejection, is big challenge to the mentally ill. They are rejected by people because of the label they carry or that their behaviors indicate that they belong to a certain labeled group.2 To report the past studies of the topic. Studies have proved that stigmatization of the mentally ill is caused by the public’s belief in myths about the dangerousnes s of the mentally ill and exposing those myths can reduce stigmatization.3 Three articles.4 Pescosolido & Tuch (2000) thought that a common respond to the mentally ill are rejection and fear of violence. Another article concluded that rejection and fear are caused by less contact with mentally ill. Alexander and Link (2003) found that any type of contact with mentally ill individuals reduced perceptions of dangerousness of the target.5 1) What are major causes for the rejection and fear, and can they be reduced?2) This finding is verified by Alexander and Link (2003).Task 2Text 11Title: Risks of Nuclear PowerAuthor(s): Bernard L. CohenSource: .Summary: Radiation from nuclear power is feared to have the potential of causing a cancer or some genetic diseases. This fear, however, is dismissed by Cohen after he compares artificial radiation and the radiation that occurs naturally in our environment, analyzing their respective impact on human health. Cohen separately discusses the different sources of nuclear power risks and arrives at the following conclusions: 1) the probability of real reactor accidents, with the safety system of defense in depth, are extremely small; 2) radioactive waste, if properly handled, causes negligible damage; 3) other radiation problems, such as accidents in transportation or radon exposures in mining, are also not so threatening as they seem to be. In summary he believes that radiation due to nuclear power will cause much fewer cancers and deaths than coal burning. (130 words)Text 12Title: How Radiation Threatens HealthAuthor(s): Nina BaiSource: Scientific AmericanSummary: Nina Bai addresses the widespread concerns over the health effects of radiation exposure in the wake of Fukushima nuclear crisis. She discusses three determinative factors: thelevel, type and duration of radiation exposure. First, radiation sickness usually occurs when there is excessive dose of exposure, though the limits of radiation level differ for the general public, radiation workers, and patients going through medical radiation. Second, of the four types of ionizing radiation, gamma, X-ray, alpha, and beta, the latter two, albeit being lower energy, are more likely to cause health damage. Third, a very high single dose of radiation can be more harmful than the same dosage accumulated over time. Finally, Bai draws on the lesson of Chernobyl, and concludes radiation exposure within reasonable limit is not so fearful and it is good to exercise caution. (136 words)Text 13Title: Should Nuclear Radiation Found in Domestic Milk Come as a Surprise?Author(s): Amber CornelioSource: http://www. Summary: Amber Cornelio (2011) maintains that radiation from Japan’s Fukushima disaster h as threatened the daily life of ordinary Americans. He challenges the government’s view that radioactive materials detected in domestic milk, vegetables and rainwater will pose no public health concern. He suspects that the government is downplaying the potential dangers of radiation to justify its use of nuclear power. He believes the government has failed to do the job of protecting people. In the end, he urges the government to be more responsible and stop building power plants on a faulty line. He warns that covering up the facts is not the key to avoid similar disasters in the future. (108 words) 66Text 14Title:Radiation and Health: The Aftershocks of Japan’s Nuclear DisasterAuthor(s): Susan BlumenthalSource: http://www. Summary: Susan Blumenthal (2011) aims to inform people of nuclear radiation with scientific facts. She starts the essay with a reference to the worldwide spread of fear in the wake of Fukushima disaster and then explains what radiation is. The explanation is followed by a report of different types of radioactive materials released into the air. She goes on to tell that an exposure to those materials will increase the risks of some major diseases. However, she concedes radiation is not so menacing as was assumed and humans are exposed to naturally occurring radiation every day. Whether radiation is harmful to health or not depends on two contexts: the duration and strength of the exposure. She warns that exposure to high doses of radiation can lead to acute health problems. Long-term low dose exposure to radiation is equally fatal. (137words)Task 3The release of substantial amounts of radiation into the atmosphere from Fukushima nuclear plant has triggered widespread concerns over the use of nuclear power and the health effects of radiation exposure. Since the Chernobyl disaster, especially the Fukushima nuclear crisis, many scientists and scholars have attempted to estimate the effect of nuclear radiation on human health. Cohen (2011) believes the fear that nuclear radiation will cause a cancer or other genetic diseases is unnecessary. He made a detailed analysis of the effects of accidents in nuclear power plants,accidents in transporting radioactive materials and escape of radioactive wastes from confinement systems on human health by comparing the effects of coal burning. Cohen arrived at the following conclusions: nuclear radiation, if properly handled, causes negligible damage and much fewer deaths than coal burning. Cohen’s idea is shared by Bai (2011). Bai discussed three determinative factors: the level, type and duration of radiation exposure. She found that radiation sickness usually occurs only when there is excessive dose of exposure. Second, of the four types of ionizing radiation, gamma, X-ray, alpha, and beta, the latter two are more likely to cause health damage. Third, a very high single dose of radiation can be more harmful than the same dosage accumulated over time. Bai concluded that radiation exposure within reasonable limit is not so fearful and it is good to exercise caution. Blumenthal (2011) did similar research. She examined different types of radioactive materials released into the air. She found that an exposure to those materials would increase the risks of some major diseases. However, the radiation is not somenacing as was assumed as humans are exposed to naturally occurring radiation every day. She believes that whether radiation is harmful to health or not depends on two contexts: the duration and strength of the exposure. Only exposure to high doses of radiation or long-term low dose exposure could lead to acute health problems.Contrary to the three scholars, however, Cornelio (2011) maintained that radiation from Japan’s Fukushima disaster threatened the daily life o f ordinary Americans. He challenges the government’s view that radioactive materials detected in domestic milk, vegetables and rainwater will pose no public health concern. He suspects that the government is downplaying the potential dangers of radiation to justify its use of nuclear power. Hence he urges the government to be more responsible and stop building power plants on a faulty line.3 Writing a literature review as a part of an essayTask 11 Content-based instruction (CBI) is an alternative approach to teaching English. In such an approach, language teaching is integrated within discipline-specific content courses. The major goal is to equip students with academic literacy skills across the curriculum. CBI has gained wide acceptance in U.S. undergraduate institutions.2 Numerous research studies demonstrate consistently that content-based second language teaching promotes both language acquisition and academic success.3 More than 10 articles.4 The literature on CBI has focused mainly on its most immediate effects, i.e., the outcomes of one or two semesters in which content-based instruction was provided. Studies on the sustained or long-term benefits of content-based language instruction are scarce.5 The writer plans to study how will C BI impact students’ future performance both in terms of academic courses and English proficiency.Task 2Nuclear Radiation and Its Long-Term Health EffectThere is a constant controversy as to the application of nuclear power and risks from nuclear radiation ever since the Chernobyl disaster. Especially the release of substantial amounts ofradiation into the atmosphere from Japan’s Fukushima Daiichi nuclear power plant in 2010 has triggered the widespread fear and concerns over risks of radiation leaks, radiation exposure, and their impact on people’s health. The commonsensical and intuitive response of the public is that nuclear radiation is most likely to cause a cancer or genetic diseases. Many researchers, however, assured the public that there is no substantial danger as assumed, and nuclear power is not as fearful or menacing as it seems to be. Cohen (2011), Blumenthal (2011) and Bai (2011), for example, cited numerical evidence and resorted to scientific facts to illustrate that a certain level of nuclear radiation risks won’t pose real danger if handled properly with the current technology available or by following the prescribed rules. They do admit the possibility of radiation initiating certain kinds of diseases, though. Only exposure to high doses of radiation or long-term low dose exposure could lead to acute health problems (Bai 2011). Nevertheless, not everyone agrees. Cornelio (2011), on the other hand, holds that nuclear radiation is most likely to threaten people’s health by contaminating milk, vegetables, and rainwater.The literature on the relationship between radiation and health largely focused on the manageability of nuclear risks and played down the damage that nuclear radiation is likely to cause. The researches generally took a detour as to whether there is any solid evidence to bear out the long-term health impact of nuclear radiation. There needs to be more well-grounded studies on the correlation between radiation and health, and on the possible long-term health effects in order to address the concerns of the general public. Besides, we also need to answer questions like “Why is there a disparity between the commonsensical feeling of the public and the explication offered by experts concerning nuclear radiation and health?”, “Are scientists biased and use the facts and statistics to their favor?” and “Is there a long-term negative health impact if one takes moderate doses of nuclear contaminated food over a long period?”Task 3Answers may vary.Task 4Answers may vary.4 CitationTask 1Order Name and date Quotation Paraphrase1 Newell and Simon (1972)√2 Feigenbaum and Feldman (1963) √3 Polya (1945)√4 Minsky (1968)√Task 2Technology plays an ever important role in the making discoveries. Throughout scientific history, many discoveries have been made because of the application of more sophisticated devises and equipment. For example, Galileo’s great discovery was attributed to the improv ementof machinery for making telescopes. And thanks to the Deep See Explorer II, life forms are now known to exist in the deeper parts of the Pacific Ocean despite the great pressure, a fact which defies the previous opinion that there was no life at the extreme depth. (Jones, 2001:125)Task 3Human activities are chiefly responsible for climate change. Despite the dispute as to whether global warming is caused by human activities (McGuire, 2001), carbon dioxide has been proved the major factor for climate change. Carbon dioxide will form a thick gas layer as it is constantly building up in the atmosphere. The gas layer is the killer of the ozone layer—the layer which protects the Earth from harmful radiation, thus causing global warming. It is documented that carbon dioxide (CO2) is emitted in a number of ways, among which the burning of fossil fuel can obviously release a great amount of CO2 into the atmosphere (Dalleva, 2007). Another way is deforestation, such as the conversion of forestland to farms, ranches, or urban use. According to Border (2011) 15 to 20% of total carbon dioxide emissions is attributed to land use changes.5 Documentation6 Avoiding plagiarismTask 1Answers may vary.Task 21 The sun rises in the east.

This view has been shifting to a constructivist view over the past decade (Merriënboer, 1997).4 Two components must be present in an instructional design theory. The first component (methods) describes how human learning will be supported, and the second component (situation) describes when certain methods ought to be used (Reigeluth, 1999).5 According to Heimlich (1992), man has always had an interest in the environment both as a source of raw materials and as a refuge for the human spirit. Nowadays, the two main e nvironmental interests are based on the concept of “a better quality of life”, as well as the need to replenish the sources of raw materials. In comparison with the pre-1960s, much greater interest in the environment is currently being expressed.6 According to Gredler (2001), the same factors apply to developing complex skills in a classroom setting as to developing complex skills in any setting. A response must be induced, then reinforced as it gets closer to the desired behavior. Reinforcers have to be scheduled carefully, and cues have to be withdrawn gradually so that the new behaviors can be transferred and maintained.Task 31. Use a synonym of a word or phrase1) They can intrude deep inside the human body where they can damage biological cells and thereby cause a cancer.2) If radioactive material is absorbed into the body, however, it is actually the lower energy alpha and beta radiation that becomes the more dangerous.3) I am simply shocked that officials are understating nuclear radiation levels in the United States as a result of the Fukushima disaster!4) Let officials be forgetful, the rest of us saw it approaching.5) On March 11, 2011, a dimension 9.0 earthquake attacked Japan, causing a destructive tsunami that tore through the coastal regions and leveled the villages in its path.2.
