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.。

实验试剂配制英语作文Title: Experiment Reagent Preparation。

In scientific research, the preparation of experimental reagents is a fundamental process that lays the groundwork for accurate experimentation and reliable results. Here, we delve into the meticulous procedures and considerations involved in the preparation of experiment reagents.Understanding the Basics:Experimental reagents are chemical substances used in laboratory experiments to bring about a specific reaction, measure a parameter, or aid in the analysis of samples. The accuracy and reliability of experimental results heavily depend on the quality and precision of these reagents.Ingredients Selection:The first step in preparing experimental reagents is tocarefully select the appropriate ingredients. This involves considering factors such as the purity of chemicals, their compatibility with other reagents, and their stability over time. Analytical grade or higher purity chemicals are typically preferred to minimize impurities that couldaffect experimental outcomes.Measurement and Calculation:Accurate measurement of ingredients is crucial to ensure the desired concentration and properties of thefinal reagent. This often requires precise laboratory instruments such as analytical balances and volumetric glassware. Calculations are then performed to determine the exact amounts of each ingredient needed based on the desired concentration and volume of the final solution.Safety Precautions:Safety is paramount when handling chemicals in the laboratory. Before beginning the preparation process, it is essential to review the safety data sheets (SDS) for allchemicals involved and take appropriate precautions to minimize risks. This may include wearing personalprotective equipment (PPE) such as gloves, goggles, and lab coats, as well as working in a well-ventilated area to prevent exposure to harmful fumes.Mixing and Dissolution:Once the ingredients are accurately measured, they are carefully mixed or dissolved in a solvent to form the final reagent solution. The mixing process should be thorough to ensure homogeneity and uniformity of the solution. In some cases, gentle heating or agitation may be required to aidin the dissolution of solids or the formation of a homogeneous mixture.Quality Control:Quality control checks are essential at various stages of the preparation process to ensure the integrity of the final reagent. This may involve visual inspection for any signs of contamination or impurities, as well as analyticaltesting to verify the concentration and purity of the reagent. Any deviations from expected values should be investigated and addressed before the reagent is used in experiments.Storage and Stability:Proper storage conditions are critical to maintaining the stability and efficacy of experimental reagents. Reagents should be stored in tightly sealed containers away from light, heat, and moisture to prevent degradation. Itis also important to label containers clearly with the contents, concentration, and preparation date to facilitate proper inventory management and traceability.Conclusion:In conclusion, the preparation of experimental reagents is a meticulous process that requires careful attention to detail, adherence to safety protocols, and strict quality control measures. By following standardized procedures and best practices, scientists can ensure the reliability andreproducibility of their experimental results, ultimately advancing our understanding of the natural world.。

评论信英文作文六下A Critical Examination of the Educational System in the United States.The United States educational system, once a beacon of academic excellence, has been facing increasing scrutiny and criticism in recent years. Despite significantfinancial investment and technological advancements, the system continues to grapple with systemic challenges that hinder student achievement and perpetuate inequities. A comprehensive examination of the current state of education in the US reveals an array of issues that warrant urgent attention.Funding Disparities and Resource Allocation.One of the most pressing concerns in the US educational system is the glaring disparity in funding between schools in different districts. Wealthy districts with higher property values can afford to invest more in their schools,providing students with access to state-of-the-art facilities, smaller class sizes, and specialized programs. In contrast, schools in low-income areas are often underfunded and overcrowded, with limited resources to support student learning. This funding gap creates an uneven playing field, disadvantaging students from underprivileged backgrounds and exacerbating educational inequalities.Curriculum and Standardized Testing.The content and delivery of the curriculum in US schools have also come under fire. Critics argue that the focus on standardized testing has narrowed the curriculum, leaving little room for creativity, exploration, and critical thinking. Teachers are forced to "teach to the test," emphasizing rote memorization and test-taking strategies over conceptual understanding and problem-solving skills. This rigid approach stifles student curiosity and limits their ability to develop a genuine love of learning.Teacher Quality and Professional Development.The quality of teachers is another crucial factor that impacts student achievement. While there are many dedicated and highly effective educators in the US, the system faces challenges in attracting and retaining qualified teachers, particularly in high-needs schools. Low salaries, limited professional development opportunities, and excessive paperwork can discourage talented individuals from pursuing teaching as a career. As a result, many schools are forced to hire underqualified or inexperienced teachers, which affects the quality of instruction and student outcomes.Inequities in Access and Opportunity.The US educational system also perpetuates significant inequities in access and opportunity. Students from racial and ethnic minority groups, low-income families, and students with disabilities face systemic barriers thatlimit their educational attainment. These barriers include discriminatory practices, biases in testing and placement, and a lack of support services. As a result, these studentsare less likely to graduate from high school, attend college, or achieve high levels of educational success.School Climate and Student Well-being.The school climate and student well-being play a vital role in academic achievement and overall student development. However, many US schools struggle to create a positive and supportive learning environment. Issues such as bullying, violence, and chronic absenteeism can disrupt the learning process and negatively impact student mental health. Furthermore, the emphasis on high-stakes testing and the pressure to perform can lead to anxiety and stress among students, impairing their academic performance and overall well-being.Conclusion.The current state of education in the United States is characterized by systemic challenges that hinder student achievement and perpetuate inequities. Funding disparities, narrow curricula, teacher quality issues, access barriers,and a lack of focus on student well-being are among the pressing concerns that need to be addressed. To build a truly equitable and effective educational system, policymakers, educators, and society as a whole must work together to implement comprehensive reforms that prioritize student success, empower teachers, and ensure that all students have access to high-quality educational opportunities.。

Experimental Procedures: A Crucial Aspect of Scientific Inquiry。

In the realm of scientific research, experimental procedures serve as the backbone of empirical investigation, facilitating the systematic exploration of hypotheses and the validation of scientific claims. Effective experimental procedures are characterized by meticulous planning,precise execution, and rigorous analysis, ensuring the reliability and validity of experimental findings. In this essay, we delve into the significance of experimental procedures and examine key elements that contribute totheir success.First and foremost, experimental procedures play a pivotal role in ensuring the reproducibility of scientific results. By providing detailed step-by-step instructions, researchers enable others to replicate their experiments and verify the robustness of their findings. Reproducibility fosters transparency and accountability in scientific research, allowing for independent validation and peer review. Moreover, it enhances the credibility of scientific knowledge by mitigating the risk of false or spurious claims.Furthermore, experimental procedures promote consistency and standardization in scientific practices. Standardized protocols enable researchers to control variables, minimize confounding factors, and maintain consistency across experimental conditions. This ensures the reliability of experimental results and facilitates comparison between different studies. Moreover, standardized procedures facilitate collaboration and knowledge exchange within the scientific community, fostering cumulative progress and innovation.Effective experimental procedures are characterized by careful attention to detail and adherence to best practices in experimental design. Prior to conducting experiments, researchers must formulate clear research questions,develop testable hypotheses, and design appropriate methodologies. This involves identifying relevant variables, selecting suitable measurement techniques, and devising controls to minimize bias and variability. Additionally, researchers must consider ethical considerations and ensure compliance with regulatory guidelines to safeguard the welfare of participants and the integrity of scientific research.During the experimental phase, meticulous execution is paramount to obtaining reliable results. Researchers must follow protocols precisely, record data accurately, and troubleshoot any unexpected challenges that arise.Attention to detail is crucial at every stage of the experiment, from preparation and calibration of equipmentto data collection and analysis. Rigorous documentation of procedures and outcomes facilitates transparency and reproducibility, allowing others to scrutinize and validatethe findings.After data collection, thorough analysis is essential to draw meaningful conclusions from the results.Statistical analysis techniques are employed to identify patterns, trends, and correlations within the data, enabling researchers to test hypotheses and infer causal relationships. Critical interpretation of findings requires consideration of potential limitations, alternative explanations, and implications for theory and practice. Moreover, researchers must communicate their findings effectively through peer-reviewed publications, presentations, and other dissemination channels to contribute to the advancement of scientific knowledge.In conclusion, experimental procedures are indispensable to the scientific method, serving as the foundation upon which empirical knowledge is built. By facilitating reproducibility, standardization, and rigor in scientific inquiry, experimental procedures contribute to the accumulation of reliable evidence and the advancement of human understanding. Through careful planning,meticulous execution, and critical analysis, researchers uphold the principles of scientific integrity and foster a culture of excellence in research.---。

US-China Foreign Language, January 2019, Vol. 17, No. 1, 43-47doi:10.17265/1539-8080/2019.01.006 A Critical Review: Evaluating the Effectiveness of ExplicitInstruction on Implicit and Explicit L2 KnowledgeSami Sulaiman AlsalmiSchool of education, University of Bristol, Bristol, United KingdomThis review discusses Akakura’s research study, entitled “valuating the Effectiveness of Explicit Instruction onImplicit and Explicit L2 Knowledge”. The argument presented here will be developed by means of a critique ofAkakura’s study, in turn addressing a summary of the study with the focus placed on the method and statisticaltechniques, as well as the evaluation of the study. Some explanations will be added to the summary of study tomake some points more obvious, specifically those that do not receive enough description in the study. In addition,given that the study is rather broad and includes many situations that are worthy of discussion but that they cannotbe covered in a paper, the evaluation will be narrowed down to concentrate on two aspects of the study: measuresof implicit knowledge and explicit instructions (treatment stage).Keywords: explicit instruction, implicit knowledge, explicit knowledgeSummary of the StudyAkakura’s (2012) study sought to explore to what extent explicit instruction can develop second-languagelearners’ implicit and explicit knowledge of English articles. Explicit instruction is concerned with “developing a metalinguistic awareness of the target rule” (Ellis, 2009, p. 54). That is, learners are provided with the instruction of the target grammatical rules. Implicit knowledge refers to the procedures comprising “knowledge which can be easily and rapidly accessed in unplanned language use. In contrast, explicit knowledge exists as a declarative fact that can only be accessed through the application of attentional processes” (Ellis, 2009, p. 12). The study claims that research has not enough discussed which measures can best test the spontaneous status of the implicit grammatical knowledge.The study employs a quasi-experimental design with a pretest/posttest and delayed test model entailing two groups: experimental (N = 49) and the control group (N = 45). In each testing stage, participants were exposed to four measures: elicited imitation task, oral production task (for implicit knowledge), grammaticality judgement task, and metalinguistic knowledge task (for explicit knowledge). A pretest was run first for the two groups, and then the experimental group was exposed to explicit instruction, using computer-assisted language learning, for one week following the pretest. The form/function mappings of articles were explained to participants, and then the participants were provided with form-focused exercises and quizzes. The posttest was administered after the participants completed article lessons achieved by explicit instruction. The delayed posttest was then completed six weeks after the treatment.Sami Sulaiman Alsalmi, Ph.D. candidate at Bristol University in the UK.All Rights Reserved.EV ALUATING THE EFFECTIVENESS OF EXPLICIT INSTRUCTION44 As indicated above, four instruments were employed to measure the two types of knowledge, and a succinct description of each measure is provided below.Elicited Imitation Task (EIT)This task required a participant to listen to a storey while looking at a sequence of pictures depicting it. Half the recorded storey contained sentences that are incompatible with the pictures and simultaneously included grammatical (N = 10) and ungrammatical (N = 10) articles. Participants were then asked to decide whether or not these sentences match the picture, and to repeat the statement when they heard a bell sound. The inclusion of picture plausibility of the storey is to ensure that a participant’s attention is on meaning and not form. The study does not describe the overall goal of this task. According to literature in the field of implicit knowledge acquisition, the underlying assumption of this task is that if a participant could repeat the statement under time constrains and orally correct the ungrammatical articles spontaneously, it would imply that the participant had internalized the target articles.Oral Production Task (OPT)In this task, participants were required to narrate the identical storey that they had been exposed to in ELT but in their own words. It was hypothesized by the authors that that using the identical pictures could minimize cognitive load during performance and raise the possibility of language complexity. Participants, furthermore, were required to think that their audiences were children. The authors hypothesized that this technique can reduce the likelihood of reliance on hearer knowledge and hence the definite article was excessively used. Grammaticality Judgement Task (GJT)Participants in this task were asked to grammatically judge the underlined portions of sentences. Thejudgement scale was created as a confidence measure requiring coding such as: 1) correct, 2) probably correct,3) probably incorrect, and 4) incorrect. Although such a task allows a participant to process the sentence for its form, time-constraint is hypothesized to stimulate a participant to access implicit knowledge. That is, the likelihood of the participant re-examining and monitoring the response is heavily reduced and that of intuitive linguistic judgement is raised, indicating a high degree of automaticity of the implicit knowledge.Metalinguistic Knowledge Task (MKT)Participants were required to correct 10 sentences and each sentence included an article error that was underlined (N = 10). Next, participants were required to give written explanations for the ungrammatical articles (N = 5). Participants were provided unlimited time to complete the task, and conducted two practice items prior to commencing. Responses were scored as either correct (1 point) or incorrect (0 points).As has already been described, the participants of experimental and control groups were exposed to each measure three times (pretest, posttest, and delayed test). To find out if the explicit instruction exerted an influence on implicit and explicit knowledge, the mean of the observed data in each measure was calculated to explore the extent to which the mean of (ex. EIT) in the pretest was statistically different from the posttest and delayed test and different between the two groups. A statistical test in this case should be employed to test the strength of mean differences between the three testing stages within one group and between the two groups. One-way ANOVA, thus, was the appropriate technique to employ in this case.The study provided a detailed and complex description of statistical data; for instance, the observed data of each measure in each group (experimental and control) was divided into four sections: non-generic articles,All Rights Reserved.EV ALUATING THE EFFECTIVENESS OF EXPLICIT INSTRUCTION 45generic articles, grammatical articles, and ungrammatical articles. Descriptive statistics were also calculated for each section. The author has sought to reorganize part of the observed data of one measure in a way that gives a patent representative sample of the results.Table 1Elicited Imitation Task (Sample)20 articlesExperimental group Control groupM SD N D M SD NPretest 10.29 3.202 49 -0.20 10.96 3.567 45Posttest 13.80 2.993 49 0.79 11.14 3.690 45Delayed test 14.98 3.058 49 1.37 10.64 3.276 45The output presented above shows that the scores generally increased over both posttest and delayed test in the Experimental Group, which outperformed the control group. ANOVA was computed to test the meandifferences of the three testing stages of the elicited imitation task between the two groups. A statisticaldifference was found in the posttest (F(1,92) = 14.866, p = 0.000) with an increase in the delayed test (F(1,92)= 44.023, p = 0.000). The results elucidated, based on the measure “EIT”, that implicit knowledge can bepromoted by explicit instruction.ANOVA was also computed for the other tasks and revealed that there is no significant difference between groups in the posttest of OPT (F(1,92) = 1.609, p = 0.208), but there was a significant difference in the delayedtask (F(1,92) = 5.161, p = 0.025). It also offered no significant difference between the groups in the posttest ofGJT (F(1,92) = 3.496, p = 0.065). However, it revealed a significant difference in the delayed test (F(1,92) =4.457, p = 0.037). Finally, ANOVA showed a significant difference between the groups in the posttest of MKT(F(1,92) = 28.787, p = 0.000). This was sustained in the delayed test (F(1,92) = 27.344, p = 0.000). (Instatistics, a p-value can never be exactly zero, but the zero here was reported based on SPSS output.) The overall findings suggest that implicit and explicit knowledge can be developed as a result of explicit instruction. In addition, the study demonstrated that the measures of implicit and explicit grammaticalknowledge can be reasonably separate. The two measures of implicit knowledge required time constraints and afocus placed on the meaning. The other measures of explicit knowledge did not entail time pressure and a focusplaced on form (greater discussion will be presented under “critique of the study”).Critique of the StudyAs suggested in the introduction, the author is going to present a concise critical discussion of measures of implicit knowledge and explicit instruction. The former was selected because one of the biggest challenges inpsycholinguistics-based research is how best to assess the spontaneous level of acquired language (implicitknowledge). The latter was chosen because it is the independent variable upon which the change in thedependent variables (explicit and implicit knowledge) occurs.Measuring implicit knowledge entails more cautious treatment to ensure that it accurately assesses the unconscious status of specific acquired structures, unlike explicit knowledge. Historically, oral production taskhas been employed to measure implicit knowledge, and although it supplies an amount of natural speech, itlacks the accurate elicitation of the spontaneous use of a specific language structure (Ellis, 2009). Putdifferently, it might give the learner a chance to use his/her explicit knowledge (to plan and monitor their All Rights Reserved.EV ALUATING THE EFFECTIVENESS OF EXPLICIT INSTRUCTION46 responses) rather than to test the spontaneous, contextualized use of a specific structure. This appears in Akakura’s study, where the oral production task reflected the difficulty of generating the specific articles. Thus, we find that the impact of explicit instruction was evident only in the delayed test, although the effect was supposed to appear in the posttest.The elicited imitation test task has been later developed (more description of this task is provided under The Summary of the Study), but some threats have appeared that might potentially affect the validity level of the EIT. Studies have revealed that an L2 learner’s attention could be turned to the form of the sentence rather than the meaning. Other studies have also elucidated that L2 learners imitate the stimulus statement by rote (Erlam, Loewen, & Philp, 2009); they repeat the statement verbatim without understanding the stimulus sentence. Akakura’s (2012) research study could achieve a pioneering success in enhancing the control of these two limitations to provide a higher level of validity. The picture plausibility is employed in the task to make a participant’s attention focus on meaning rather than on form. In addition, it provides a chance for delaying repetition so that participants do not repeat the sentence verbatim. In Rebuschat and William’s (2012) study, semi-artificial grammar is used and participants are required to listen to statements on an item-by-item basis, to judge the plausibility of the semantics of the stimulus statement, and then to repeat the statement. In Erlam, Loewen, and Philp’s (2009) study, the statements are designed to enable the subjects to decide whether they agree with, disagree with, or do not comprehend a statement. However, a storey-based elicited imitation test had not been previously employed to measure implicit knowledge, and it is considered, to my knowledge, that its first use was in the Akakura (2012) study.When a deeper scrutiny is applied to measures of implicit knowledge, we explore that the EIT includes a choice that can increase the level of internal validity, such as the choice not sure (if the sentence fits with thepicture). This is because, if some participants guessed the option correctly more by luck than by judgement, it isexpected that they would not correctly guess during the posttest or delayed-test phase, and then that they would obtain a low score. This threat, statistically, implies that the scores in the distribution regress to the mean as a result of guesswork, not of the explicit instruction itself (Gravetter & Forzano, 2011).The oral production test, as indicated above, might fail to bolster the rigour of the measure of implicit knowledge, and, additionally, it could be influenced by the tutors’ personal prejudices, resulting in a low level of reliability. For instance, some tutors might lose control or their confidence when they are assessing enormous amounts of free natural speech, and, accordingly, they might be inclined to give participants scores in the middle range to ward off severe errors (Morgan, Dunn, Parry, & O’Reilly, 2003). The study further failed to provide a patent description of how the oral production test is achieved and how the data are gathered in a numerical pattern.However, at the treatment stage of the study procedure, the study does not exactly elucidate the role of the researcher—for example, regarding who has taught the participants, the researcher himself or another hired tutor. In addition, the treatment stage is confined to only one learning condition. Other learning conditions of explicit instruction are not addressed in the study. Snobul and Schmitt (2013), for instance, employed three learning conditions—enriched input, enhanced input, and decontextualized input—to evaluate under which conditions both adult native speakers and advanced non-native speakers of English acquire collocations. Tagarelli, Mota and Rebuschat (2015) used two conditions: implicit and explicit input. In the implicit learning condition, subjects were aware of neither the underlying goal of the experiment nor the target knowledge that would be learned or tested . The explicit learning condition is similar to the condition employed in Akakura’sAll Rights Reserved.EV ALUATING THE EFFECTIVENESS OF EXPLICIT INSTRUCTION 47(2012) study, where participants were aware of what knowledge they would acquire. The author considers thatthe Akakura (2012) study could be enhanced if more learning conditions were included to determine whichimplicit knowledge and explicit knowledge of English articles might best be developed.In summary, the study succeeded in bolstering control of the limitations of EIT, in clearly describing the instruction process and in employing the appropriate statistical test (ANOVA). Nonetheless, some threats in thestudy need to be reduced by a more careful treatment related to validity and reliability, such as guesswork andan oral production task. Some further directions have been suggested to improve the treatment stage, such asemploying more than one learning condition in the treatment stage.Finally, the method used has many crucial implications, and the most promising one appears to be pedagogy. For instance, when an L2 learner obtains a high score in grammar, this does not imply that the learnerhas externalized the target rule and thus can use it spontaneously and in unplanned language use. Rather, it showshow well a learner might apply the rule in a context in which close analysis of text is involved. Therefore, policymakers in education should be aware of the learning conditions that enhance not only explicit knowledge but alsoimplicit knowledge, which is considered the chief aim of language learning.ReferencesAkakura, M.

附录2 英文文献中文译文采用微核和RAPD研究波斯湾岩石牡蛎的遗传毒性Farhadi,A.Farahmand,H.*,Mirvaghefi,A.and Khalili,B摘要：微核（MN)和双核（BN）以及RAPD（随机扩增多态性DNA）被作为新的生物标志物，对双壳贝类，鱼类，甚至人类进行了毒性损伤及相关的遗传毒性研究。

然而，到目前为止，在伊朗的波斯湾还没有这样的研究记录。

对于这个提议，我们分析了从两个地区收集岩石牡蛎的鳃细胞微核的频率和RAPD分析，结果显示出石油污染物相对较高。

研究结果显示Mahshahr码头岩石牡蛎的微核频率显著高于Dayer 码头（(p<0.05）。

在Mahshahr码头的个体中也观察到双核细胞。

此外，RAPD分析表明在污染区域个体间有较小多样性。

这项研究表明，微核和RAPD分析被认为是对波斯湾沿海地区水生生物多样性的污染评价的有效的方法。

关键字:微核，双核，RAPD，岩石牡蛎，污染前言目前，工业、农业和生活废弃物直接进入地表水体，对其造成生态破坏，越来越引起人们的关注(Taseli,2009,Nasrabadi et al.,2010, Nabi bidhendi et al.,2007,Mahmoudi et al.,2010, Nakane and Haidary, 2010)。

这些污染物大多具有遗传毒性(Jha et al.,2004; Ohea et al.,2004; Chen and White,2004)。

牡蛎是一种滤食性动物(Saccostrea cuculata Born, 1778)，营固着生活，大多生活在多岩石的海岸，如波斯湾码头海岸(Hosseinzadeh, 1991)。

因为生活方式的原因，这类生物也无法避免这种污染，(Salzar and Salzar, 2001)。

这个物种有微弱的解读能力，所以他们能够很好地反映这种毒性。

可以使用生物监测的新方法来检测这个指标(Monserrat et al.,2006)。

临床实验流程英文版Clinical Trial ProcessIntroductionClinical trials play a crucial role in the development and evaluation of new medical treatments and interventions. They are essential for ensuring that these interventions are safe and effective before they are made available to the general population. This article aims to provide an overview of the clinical trial process, outlining the key steps involved and their significance.1. Study DesignThe first step in the clinical trial process is the design of the study. This involves defining the research objective, selecting appropriate study participants, and determining the specific interventions or treatments to be tested. The study design should also incorporate measures to minimize bias and ensure the reliability of the results.2. Ethical ConsiderationsBefore a clinical trial can proceed, it must undergo an ethical review to ensure that it meets the necessary ethical standards. This involves obtaining approval from an institutional review board or an independent ethics committee. This ensures the protection of participants' rights and welfare throughout the trial.3. Informed ConsentInformed consent is a critical aspect of the clinical trial process. Participants must be provided with all relevant information about the study,including potential risks and benefits, treatment alternatives, and their right to withdraw at any time. Informed consent ensures that participants make a voluntary and informed decision to participate.4. Randomization and BlindingRandomization is a method used to minimize bias and ensure that participants are allocated to treatment groups in a fair and unbiased manner. This helps to ensure that the results of the study are not influenced by factors other than the intervention being tested. Blinding, either single-blind or double-blind, is employed to eliminate bias in the assessment of outcomes.5. Recruitment and EnrollmentOnce the study design is finalized and ethical approval is obtained, the recruitment and enrollment process can commence. Participants who meet the predetermined eligibility criteria are invited to participate in the trial. Recruitment efforts may involve various strategies, such as advertisements or referrals from healthcare professionals.6. Intervention and Control GroupsParticipants in a clinical trial are divided into two or more groups: the intervention group, which receives the experimental treatment, and the control group, which receives either a placebo or the standard treatment. This comparison allows researchers to assess the efficacy and safety of the intervention being tested.7. Data Collection and MonitoringThroughout the trial, data is collected to evaluate the outcomes of the intervention. Data collection methods may include interviews, physical examinations, laboratory tests, and imaging studies. Regular monitoring and quality control procedures are implemented to ensure the accuracy and reliability of the collected data.8. Data Analysis and InterpretationOnce data collection is completed, the next step is data analysis and interpretation. Statistical analysis techniques are applied to determine the significance of the results and to draw conclusions about the efficacy and safety of the intervention. The findings are then interpreted in the context of existing scientific knowledge.9. Publication and ReportingThe final step in the clinical trial process involves the publication and reporting of the results. Researchers are responsible for preparing manuscripts that present their findings in a clear and concise manner. Peer-reviewed journals are the primary platform for disseminating the trial results, contributing to the body of scientific knowledge.ConclusionThe clinical trial process is a rigorous and systematic approach to evaluate the safety and efficacy of new medical interventions. From study design to publication of results, each step plays a vital role in ensuring the reliability and generalizability of the findings. By adhering to ethical standards and employing robust research methodologies, clinical trials contribute to advancements in healthcare, benefiting patients worldwide.。

experimental research results -回复Experimental research results are an important aspect of scientific inquiry, providing evidence-based insights into various phenomena. In this article, we will explore the steps involved in conducting experimental research and analyze the results obtained. By following the systematic approach of experimental design, researchers can ensure the validity and reliability of their findings.The first step in conducting experimental research is to identify the research question or hypothesis. This sets the direction for the experiment and helps define the variables under investigation. For example, let's consider a research question: "Does regular exercise improve cognitive function in older adults?"Once the research question is established, the next step is to design the experiment by outlining the variables, experimental groups, and control conditions. In our case, the dependent variable is cognitive function, while the independent variable is exercise. The experimental group consists of older adults who will engage in regular exercise, while the control group comprises individuals who do not exercise.The third step involves selecting the participants for the study. It is crucial to ensure randomization and homogeneity among the participants to minimize any confounding factors that could affect the results. In our scenario, researchers would recruit a diverse group of older adults with similar baseline cognitive abilities.After selecting the participants, researchers proceed to collect baseline data on their cognitive function before the intervention. This serves as a point of comparison to assess the impact of exercise on cognitive function. Various standardized tests and measurements can be employed to evaluate cognitive abilities, such as memory, attention, and problem-solving skills.Once the baseline data is collected, the experimental group begins the exercise intervention, while the control group does not engage in any exercise during this period. The exercise regimen should be well-defined, consistent, and tailored to the abilities of the participants. Ideally, researchers should monitor and encourage adherence to the exercise program throughout the study.After an appropriate duration of intervention, typically several weeks or months, the post-intervention cognitive function isassessed for both the experimental and control groups. This data is then compared to the baseline measurements to determine any changes or improvements resulting from the exercise intervention.Statistical analysis plays a crucial role in interpreting the experimental research results. Researchers employ various statistical methods to determine the significance of the findings and quantify the effect size. In our example, statistical tests could reveal whether the exercise group performs significantly better on cognitive tests compared to the control group.The final step involves drawing conclusions based on the results obtained. Researchers may find that regular exercise has a positive impact on cognitive function in older adults, as indicated by significant improvements on cognitive tests. It is important to acknowledge any limitations or potential confounding factors that may have influenced the results and consider avenues for further research in the field.In conclusion, experimental research results provide valuable insights into scientific phenomena. By following a systematicapproach consisting of defining the research question, designing the experiment, selecting participants, collecting baseline data, implementing the intervention, analyzing the results, and drawing conclusions, researchers ensure the validity and reliability of their findings. While this article focused on a specific research question, the steps outlined here can be broadly applied to experimental research in various disciplines.。
