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。

大学学术英语教材答案Unit 1: Reading ComprehensionPart A1. C2. B3. D4. A5. CPart B6. The main idea of the passage is that there are several effective strategies to help non-English speaking international students improve their academic English writing skills.7. The author suggests that non-English speaking international students should read extensively, practice writing regularly, seek feedback from professors or writing centers, and participate in academic writing workshops.8. The term "discourse community" refers to a group of people who share common goals, knowledge, and ways of communication within a specific academic field or profession.9.

Third, it helps develop communication and interpersonal skills as students interact and negotiate with their peers. Overall, group work provides a more engaging and interactive learning experience.Part B37. In my opinion, the most effective method of note-taking depends on individual preferences and learning styles. For visual learners, using mind maps or diagrams can be helpful in organizing information. For auditory learners, recording lectures and listening to them later can aid in comprehension.

Ultimately, students should experiment with different methods and find what works best for them.Unit 5: WritingPart A38. Introduction: The purpose of this essay is to discuss the advantages and disadvantages of using social media in education.39. Advantages: Social media can facilitate communication between students and professors, allow for easy access to educational resources, and promote collaborative learning.40. Disadvantages: Social media can lead to distractions, privacy concerns, and potential misinformation or lack of credible sources.41. Conclusion: In conclusion, the use of social media in education has both positive and negative implications. It is crucial for educators and students to approach it mindfully, making use of its benefits while being aware of its drawbacks.Part B42. In my opinion, it is essential for universities to provide academic English courses for non-English speaking students. These courses can help students improve their language skills, particularly in academic writing and speaking. Proficiency in academic English is crucial for success in higher education and future careers. Additionally, these courses can also provide cultural orientation and support, helping international students navigate the challenges of studying in a foreign country. Overall, academic English courses contribute to a more inclusive and supportive learning environment for all students.Note: This sample answer is for reference only and may vary depending on the specific questions and content of the textbook.

Your essay should cover the following points:- The increasing demand for energy and the challenges of relying on fossil fuels.- The benefits of renewable energy sources, such as solar,wind, and hydroelectric power.- The role of technology in advancing renewable energy solutions.- The economic and environmental implications of a transition to renewable energy.- The need for policy support and public awareness to promote the adoption of renewable energy.Sample Essay:The 21st century has ushered in an era of unprecedented energy demand, driven by global population growth and industrialization. Traditional fossil fuels, while abundant, present significant challenges, including environmental degradation and the potential for resource depletion. In contrast, renewable energy sources offer a sustainable alternative that can help mitigate these issues.Renewable energy, derived from the sun, wind, and water, among other sources, is inexhaustible and clean. Solar panels convert sunlight into electricity, wind turbines harness the power of the wind, and hydroelectric dams utilize the force of flowing water. These technologies not only reduce greenhouse gas emissions but also decrease our dependence on finite resources.Advancements in technology have made renewable energy more efficient and cost-effective. Innovations in energy storage and grid integration are addressing the intermittency of renewable sources, making them more reliable and accessible. Furthermore, the transition to renewable energy is aneconomic opportunity, with the potential to create new jobs and stimulate growth in the clean energy sector.However, the shift to renewable energy requires robust policy support and public awareness. Governments must enact incentives for renewable energy development and implement regulations that reduce the environmental impact oftraditional energy sources. Public education campaigns can also play a crucial role in fostering a societal understanding of the benefits of renewable energy and encouraging its adoption.In conclusion, the importance of renewable energy in the 21st century cannot be overstated. As we face the dual challenges of energy scarcity and environmental sustainability, renewable energy offers a promising path forward. With continued innovation, policy support, and public engagement, we can harness the power of the sun, wind, and water to build a cleaner。

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 UnionTB in urban centers like New York CityRising 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 patientCorrect 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 groupTendency to produce comparable groupsGuaranteed validity of statistical tests of significanceLimitations:Difficulty in generalizing the results obtained from the selected sampling to the population as a wholeA poor choice for research where temporal factors are anissueExtremely heavy resources, requiring very large samplegroupsQuasi-experimentsAdvantages:Control group comparisons possibleReduced 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 groupsCohort studiesAdvantages:Clear indication of the temporal sequence between exposure and outcomeParticular use for evaluating the effects of rare or unusual exposureAbility to examine multiple outcomes of a single risk factorLimitations:Larger, longer, and more expensiveProne to certain types of biasNot practical for rare outcomesCase-control studiesAdvantages:The only feasible method in the case of rare diseases and those with longperiods between exposure and outcomeTime 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 natureDifficult to establish the timeline of exposure to disease outcomeN=1” trials“AdvantagesEasy to manageInexpensiveLimitations：Findings difficult to be generalized to the whole populationWeakest 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 stressPainHardships·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 vitalityA certain zip in gaitA 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-truthFearful fictionsBlatant 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 dimensionsBuilding our wellness toolbox slowlyPicturing our whole state of being·Attention to the little stuff:Examining our lives honestly and setting clear intentions to changeStriving to maintain a balance of our mind, body and spiritTaking 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 emotionsUnit61、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 newset 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 treatmentchoices, 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 ahospital 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.7、·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 startcomfort 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 doctor4、·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 havingthe patient make decisions on their own.·Balancing between paternalism and respect for patients autonomy constitutes alarge 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 therapyNotable departure s from standard practice being called “experimental” withl”and “research” carelessly definedthe terms “experimenta2、·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 seedingthe 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 research 5、·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 formAdequate information as the premiseA 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: fairnessAt the social level: distinction between classes。

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. Change the order of information1) How the spent fuel is dealt with determines the effects of routine releases of radioactivity from nuclear plants.2) It is difficult to measure the effects of long-term, low-dose radiation.3) One indication of the terrible situation in Japan is that no sensible man wants to visit there again for the next 80 to 100 years.4) Understandably, panic among masses is what the authorities try to avoid.5) Burns or other symptoms of acute radiation syndrome (ARS) vary from person to persondepending on the strength of radiation and the level of exposure.3. Change from the active to the passive or vice versa1) Our cancer risk should be eventually increased by 0.002% (one part in 50,000), thus our life expectancy reduced by less than one hour due to the radiation brought by nuclear technology. 2) 180,000 people have been evacuated by the Japanese government from within a 20 kilometer radius of the Fukushima Daiichi complex.3) Farmers in Japan were asked to keep cows and cattle in barns by Government officials as radioactive contamination of milk spread from Fukushima prefecture, north of Tokyo.4) A sheet of paper can often block Alpha and beta particle radiation as it is lower energy.5) A broad range of acute health problems will arise only among the individuals who are exposed to high doses of radiation such as reactor worker.4. Change the positive into the negative and vice versa1) Since our body cells fail to distinguish between natural radiation and radiation from the nuclear industry.2) No number of noticeable deaths from coal burning was larger than in an air pollution incident where there were 3,500 extra deaths in one week.3) Should any increase in radiation due to a nuclear disaster instead of naturally occurring, be of concern?4) The dairy industry will not stop working closely with federal and state government agencies to ensure that we maintain a safe milk supply.5) Almost no one will experience a broad range of acute health problems due to their exposure to high doses of radiation except for the individuals close to the source of radiation such as reactor workers.5. Change personal nouns into impersonal nouns and vice versa1) The attack of sex cells can cause genetic diseases in progeny.2) Unawareness of the danger led parents to serve contaminated milk to their children.3) Our perplexity results from the increases in diseases, obesity and erratic behavior among our malnutritioned populace.4) Then again, officials tend to downplay everything, so that panic doesn’t occur among the masses.5) A person who is exposed to low dose but long-term radiation will develop chronic health condition including cancer.6. Change complex sentences into simple sentences and vice versa1) There is little likelihood, if any, for the failure of each system in this series of back-ups exists.2) We should not be worried at all.3) The increase in cancer risk is too small to determine unless many exposed subjects are studies.4) Any exposure will lead to certain damage and safety problem.5) Despite a lot of news distraction, we still notice the dire current situation.8 Enhancing your academic languageReading: Text 111 Match the words with their definitions.1 i2 f3 g4 c5 h6 a7 b8 e9 d 10 j2 Complete the following expressions or sentences by using the target words listed below with the help of the Chinese in brackets.
