Critical Review怎么写Writing a Critical ReviewThe advice in this brochure is a general guide only. We strongly recommend that you also follow your assignment instructions and seek clarification from your lecturer/tutor if needed.Purpose of a Critical ReviewThe critical review is a writing task that asks you to summarize and evaluate a text. The critical review can be of a book, a chapter, or a journal article. Writing the critical review usually requires you to read the selected text in detail and to also read other related texts so that you can present a fair and reasonable evaluation of the selected text.What is meant by critical?At university, to be critical does not mean to criticize in a negative manner. Rather it requires you to question the information and opinions in a text and present your evaluation or judgment of the text. To do this well, you should attempt to understand the topic from different perspectives (i.e. read related texts) and in relation to the theories, approaches and frameworks in your course. What is meant by evaluation or judgment?Here you decide the strengths and weaknesses of a text. This is usually based on specific criteria. Evaluating requires an understanding of not just the content of the text, but also an understanding of a text’s purpose, the intended audience and why it is structured the way it is.What is meant by analysis?Analyzing requires separating the content and concepts of a text into their main components and then understanding how these interrelate, connect and possibly influence each other.Structure of a Critical ReviewCritical reviews, both short (one page) and long (four pages), usually have a similar structure. Check your assignment instructions for formatting and structural specifications. Headings are usually optional for longer reviews and can be helpful for the reader.IntroductionThe length of an introduction is usually one paragraph for a journal article review and two or three paragraphs for a longer book review. Include a few opening sentences that announce the author(s) and the title, and briefly explain the topic of the text. Present the aim of the text and summarize the main finding or key argument. Conclude the introduction with a brief statement of your evaluation of the text. This can be a positive or negative evaluation or, as is usually the case, a mixed response.SummaryPresent a summary of the key points along with a limited number of examples. You can also briefly explain the author’s purpose/intentions throughout the text and you may briefly describe how the text is organized. The summary should only make up about a third of the critical review. CritiqueThe critique should be a balanced discussion and evaluation of the strengths, weakness and notable features of the text. Remember to base your discussion on specific criteria. Good reviews also include other sources to support your evaluation (remember to reference).You can choose how to sequence your critique. Here are some examples to get you started: •Most important to least impor tant conclusions you make about the text.•If your critique is more positive than negative, then present the negative points first and thepositive last.•If your critique is more negative than positive, then present the positive points first and the negative last.•If there are both strengths and weakness for each criterion you use, you need to decide overall what your judgment is. For example, you may want to comment on a key idea in the text and have both positive and negative comments. You could begin by stating what is good about the idea and then concede and explain how it is limited in some way. While this example shows a mixed evaluation, overall you are probably being more negative than positive.•In long reviews, you can address each criteria you c hoose in a paragraph, including both negative and positive points. For very short critical reviews (one page or less) where your comments will be briefer, include a paragraph of positive aspects and another of negative.•You can also include recommendatio ns for how the text can be improved in terms of ideas, research approach; theories or frameworks used can also be included in the critique section. ConclusionThis is usually a very short paragraph.•Restate your overall opinion of the text.•Briefly prese nt recommendations.•If necessary some further qualification or explanation of your judgment can be included. This can help your critique sound fair and reasonable.ReferencesIf you have used other sources in you review you should also include a list of references at the end of the review.Summarizing and paraphrasing for the critical reviewSummarizing and paraphrasing are essential skills for academic writing and in particular, the critical review. To summarize means to reduce a text to its main points and its most important ideas. The length of your summary for a critical review should only be about one quarter to one third of the whole critical review. The best way to summarize is to:1.Scan the text. Look for information that can be deduced from the introduction, conclusion and the title and headings. What do these tell you about the main points of the article?2.Locate the topic sentences and highlight the main points as you read.3.Reread the text and make separate notes of the main points. Examples and evidence do not need to be included at this stage. Usually they are used selectively in your critique.Paraphrasing means putting it into your own words. Paraphrasing offers an alternative to using direct quotations in your summary (and the critique) and can be an efficient way to integrate your summary notes.The best way to paraphrase is to:1.Review your summary notes2.Rewrite them in your own words and in complete sentencese reporting verbs and phrases (eg; The author describes…, Smith argues that …).4.If you include unique or specialist phrases from the text, use quotation marks.。

IntroductionIn Man’s Search for Meaning, Viktor E. Frankl tells the very per sonal story of his experience as a prisoner in a concentration camp during the Holocaust. He presents this story in the form of an ess ay in which he shares his arguments and analysis as a doctor and psychologist as well as a former prisoner. This paper will review Fra nkl’s story as well as his main arguments, and will evaluate the qu ality of Frankl’s writing and focus on any areas of weakness within the story.SummaryThis section contains a summary of Man's Search. Frankl begins his book by stating that his purpose in writing the book is not to present facts and details of the Holocaust, but to provide a persona l account of the everyday life of a prisoner living in a concentration camp. He states, “This tale is not concerned with the great horror s, which have already been described often enough (though less oft en believed), but…it will try to answer this question: How was ever yday life in a concentration camp reflected in the mind of the aver age prisoner?”(21). Frankl then goes on to describe the three stag es of a prisoner’s psychological reactions to being held captive in a concentration camp.The first phase, which occurs just after the prisoner is admitted to the camp, is shock. The second phase, occurring once the priso ner has fallen into a routine within the camp, is one of apathy, or “the blunting of the emotions and the feeling that one could not anymore”(42). The third phase, which occurs after the prisoner ha s been liberated from the camp, is a period of “depersonalization”, in which “everything appears unreal, unlikely, as in a dream”(11 0). In this phase, released prisoners also feel a sense of “bitterness and disillusionment”when returning to their former lives (113). Fr ankl describes each of these phases using psychological theory and provides personal experiences to exemplify each of the stages.Author’s ArgumentsAs described above, Frankl’s main purpose for writing this book is to pr esent and analyze the average prisoner’s psychological reactions to the every day life of a concentration camp. His three main arguments are his presentat ion and analysis of each of the psychological stages that the average concent ration camp prisoner experiences: shock, apathy and depersonalization. He b ases his analyses of each of these stages on the actions of the prisoners and his own personal thoughts and reactions as he experienced life in a concent ration camp.For example, Frankl argues that the second phase of apathy forces “the prisoner’s life down to a primitive level”(47) in which “all efforts and all e motions were centered on one task: preserving one’s own life and that of t he other fellow”(47). He bases this theory on events he witnessed while livi ng in the camp himself, and states, “It was natural that the desire for food was the major primitive instinct around which mental life centered. Let us ob serve the majority of prisoners when they happened to work near each other and were, for once, not closely watched. They would immediately start discu ssing food”(48). Frankl continuously uses examples from his experiences in t he concentration camp to illustrate and strengthen his psychological argumen ts throughout the text.EvaluationThis section contains an evaluation of Frankl’s book. Firstly, the author i s a survivor of the Holocaust and was a prisoner of a concentration camp hi mself, which gives him the personal insight to be able to comment on the ps ychological conditions of an average prisoner. However, this also creates a bi as and because of his personal experience, he is unable to be entirely objecti ve in writing his analysis. Frankl acknowledges this bias in the beginning of his book, by stating, “Only the man inside knows. His judgments may not b e objective, his evaluations may be out of proportion. This is inevitable. An attempt must be made to avoid any personal bias, and that is the real difficu lty of a book of this kind”(24-25). Although he is aware of this bias, it crea tes a partiality that will sway the readers throughout his story and it serves a s a minor weakness in his writing style.A second weakness in Frankl’s writing is in the assumptions he sometim es makes to prove his point. He makes overarching generalizations several ti mes in his book, making statements that, although may have been true for hi mself and those around him, might not have been true for every prisoner in every concentration camp during the Holocaust. For example, in one instance, he says, “The prisoner of Auschwitz , in the first phase of shock, did not fear death”(37). It is very bold to say that no prisoner of Auschwitz, one of t he most well-known and deadly concentration camps of the Holocaust, did n ot fear death, as death was all around them and was a very real threat in th eir daily lives. Although he might have not feared death during his phase of shock, it is impossible for him to guarantee that no prisoner was at all fearf ul of death in this first psychological phase, and for him to make overarching assumptions like this is a weakness to the overall quality of his book.Finally, Frankl sometimes becomes too technical and verbose in his writin g style, which makes it very hard for the average reader to understand. One example of this is as follows. Frankl states, “I remember an incident when t here was an occasion for psychotherapeutic work on the inmates of a whole hut, due to an intensification of their receptiveness because of a certain exter nal situation”(102). This sentence, which is overly wordy and complicated, m akes it difficult for the average reader to understand exactly what he is sayin g. A reader can easily get frustrated when trying to decipher the author’s m eaning due to overly complicated language, and this is a third weakness of F rankl’s writing.ConclusionThis critical review has evaluated the book Man’s Search for Meaning by Viktor E. Frankl. The psychological theories that Frankl presents are very inte resting and he does a good job of illustrating these theories with his own pe rsonal experiences. However, his writing is weakened by the presence of bias, the overarching assumptions he occasionally makes, and his sometimes overl y technical and verbose language.。

Student name: han gao, student number: 12252196Critical review-----------------------The technology of Fracking Introduction:In the modern world, the shortage of energy has increasingly become an extremely urgent problem for all the people’s living. FORGET coal, it's too dirty. Forget nuclear power, it's too expensive and controversial. Forget renewable, they're too unpredictable. To achieve our energy needs and reduce carbon emissions we need an abundant source of clean, cheap energy, available night and day. The substitution of conventional fuel will be the first option for us. The shale gas is a satisfactory answer, although drilling for shale gas can cut energy prices and lessen reliance on imports, critics warns are still existing that the process can result in earth tremors and pollute water supplies, I will discuss and evaluate about the strengths, weakness and notable features of the text.Summary:The author explained that what the technique of facking is and how to release the gas from the shale-bed. Hydraulic fracturing –also known as “fracking” –it is a two-phase process of extracting shale gas from gas site thousands of metres below ground. The first phase includes drilling the wells, the second uses high-pressure fracking fluid some chemicals and sand-laden gel to fracture shale rock and release the gas.Critique:Drilling phase: time to drill a well from the selected site to total depth is about 3-6 weeks depending on depth and length of horizontal well. The initial part of a horizontal well is drilled the same way as a common vertical well. The method changes when the borehole reaches shale-bed 300-600 feet below ground, this known as the bending point (kick-off-point). At this point the conventional drilling machinery is pulled back up out of the well and replaced by special horizontal drilling machinery. During the process of drilling well, it is possible to puncture the aquifer which contains the fresh water used for drinking for localresidents and the water-bearing rock is at average depth of 100 meters. The author introduced a duct of fresh water protection which is 3 sets of steel casings, in order to cement the place where punctured the aquifer prevent the accidental pollution of drinking water layer. The strength of the technique during this phase is that the new duct of drilling has been replaced by a 3 sets of steel casings. It can avoid the leaking of fluid which includes toxicant.Fracking phase:Hydraulic fracturing fluids which include water(95%), sand(4.5%) and additives(0.5%) are pumped at high pressure, over 100bar into the well. Then increasing the pressure in the well, the fracturing fluid can break the shale rock apart until rocks are cracked to expected length 200-300m. Typically requires 20,000 cubic metres of water – equivalent to 500 tankers – plus1,800t of sand, blended with 100t of additives to promote gelling. Back-flushing is that fracturingwaste-water will be pumped out of well for disposal or re-use. The process of fracturing rock with the liquid of blends has been resulting in a number of environmental problems, and thegroundwater contamination is the most significant environmental issue which is completely related to people’s life, because of the compositions of fracturing fluid contain a mass of toxic material which I mentioned as additives in fluid(0.5%) (heavy metal ion, chemicals and so on), by the process of fracturing, the fracking fluid will has polluted the aquifers, soil and rock. Many of the chemicals found in drilling and evaporation pits are considered hazardous wastes by experts. Toxic chemicals are used at every stage of production to find shale gas and take them out, even fracturing. For releasing the shale gas after fracking, this kind of fluid is injected underground under high pressure. The well can be fracked many times and it can be up to 35 wells on one well site. A 30% to 70% of the fracking fluid will resurface and bring back with it the toxic substances and others chemicals. Although the author mentioned a new duct of fracking fluid with 3 sets of steel casings, the risks still exist within fracturing phase. Gas-flow: Sand remains, holding fractures open to allow gas to flow into well. Fracking process takes up to 10 days.Conclusion:Discussing and evaluation the technology of shale gas generation as given above. As the development of production of shale gas, the new and reasonable skills have been used in every phase. For the environmental problem possibly caused by fracking, the author has not presenteda effective solution yet, so the risks of Groundwater contamination remain.Reference:1.。
