lecture英语范文
lecture英语范文英文回答:Lecture.A lecture is a formal presentation delivered by an expert or specialist, typically in an academic or professional setting. The primary purpose of a lecture is to impart knowledge, convey information, or share insights on a specific topic. Unlike other forms of oral communication, lectures are usually one-sided, with the speaker assuming the role of an authoritative figure who imparts knowledge to the audience.Characteristics of a Lecture:Structured and well-organized: Lectures follow a logical flow of ideas, with an introduction, body, and conclusion. The speaker provides a clear outline or agenda to guide the audience through the presentation.Focused on a specific topic: Lectures are typically narrowly focused on a particular subject matter, allowing the speaker to delve deeply into the topic and present detailed information.Formal and authoritative: The speaker in a lecture is usually an expert or specialist in the field, showcasing their knowledge and expertise. The presentation is often formal in tone and delivery.One-sided communication: Lectures are primarily a one-sided form of communication, with the speaker delivering information to the audience. There is limited opportunity for audience participation or interaction.Note-taking and active listening: Attendees typically take notes during a lecture to record key points and enhance understanding. Active listening is also crucial for retaining information presented during the lecture.Benefits of Lectures:Imparting knowledge: Lectures effectively convey complex information to an audience, providing detailed explanations and examples.Sharing insights and perspectives: Experts can share their unique insights, perspectives, and the latest research findings through lectures.Building a foundation: Lectures lay the groundwork for further study or exploration of a subject, providing a comprehensive overview and key concepts.Improving comprehension: The structured nature of lectures helps learners organize and understand complex ideas.Inspiration and motivation: Lectures can inspire and motivate attendees, sparking interest and enthusiasm for the subject matter.Drawbacks of Lectures:Passive learning: Lectures can be passive experiences for attendees, limiting active engagement and critical thinking.Limited interaction: The one-sided nature of lectures restricts opportunities for audience participation and clarification.Short attention span: Maintaining attention during a long lecture can be challenging, especially if the content is not engaging or relevant.Cognitive overload: Lectures can overwhelm attendees with excessive information, hindering comprehension and retention.Cultural differences: Cultural factors can influence lecture delivery and audience engagement, affecting the effectiveness of the communication.Conclusion:Lectures are an effective form of knowledge dissemination in academic and professional settings. They enable experts to share their knowledge, provide in-depth information, and inspire audiences. However, it is important to acknowledge the limitations of lectures and incorporate interactive elements to enhance learner engagement and comprehension.中文回答:演讲。

A scratch outline
Thesis statement: A church experiment led to my spending the morning in a wheelchair. Sitting in the wheelchair Awkward because it rolled Awkward because footrest was out of place Psychologically awkward Moving the wheelchair I thought someone would push me. It was hard to make the chair move and it hurt my hand. It was difficult to steer. ways the wheelchair affected me I couldn’t see. I felt in the way. I felt funny talking to people as they bent down oveugh Revising.
The introduction should explain why the pastor wanted us to adopt disabilities. The second paragraph is sort of weak. Instead of saying “I’m not sure why I felt scared,” I should try to put into specific words what was scary about the experience. The stuff about Paula doesn’t really add to my main point. The story is about me, not Paula. Maybe I shouldn’t talk so much about the new building program. It’s related to people with disabilities, but it doesn’t really support the idea that my morning in a wheelchair was frustrating. Eliminate the part about Don Henderson. It doesn’t contribute to my feeling frustrated. The essay ends too abruptly. I need to wrap it up with some sort of conclusion.
howtogiveaneffectivepresentation:如何提供有效的演示
How to Give an Effective PresentationJannette Collins, MD, MEd, FCCPUniversity of Wisconsin Hospital and ClinicsIntroductionWhen asked for a definition of CME (continuing medical education), many physicians will describe a short course with instructors presenting didactic lectures to large groups of physicians sitting for long hours in a hotel conference room in rows of narrow tables. The lecture is the staple format of CME course instruction. Lectures have been viewed as a poor method to promote the development of thinking skills for the formation of attitudes [1-3]. The main reason for this is the lack of involvement by the participants who remain passive recipients of information. However, when done effectively, the lecture can allow participants to learn new material, explain difficult concepts, organize thinking, promote problem solving, and challenge attitudes [4-6]."Teach the teachers" workshops and courses, which introduce participants to interactive lecturing, lead to lectures that increase student participation and involvement in the large class lecture [7]. The objectives of this presentation are for the participants to be able to differentiate good and bad features of a presentation, evaluate their own and other’s presentation skills, and improve their own presentation skills.Speaker evaluations from the 2002 STR CourseAnalysis of comments from individual speaker evaluations from the STR 2002 Course revealed common features of ineffective lecturing (Table) [8]. The negative feature that was commented on most often (12.4%), and directed at the largest number of faculty (63%) was poor content. Other negative features included poor delivery, image slides, text slides, command of the English language, and handouts. Positive comments did not provide descriptive information regarding effective lectures.Table. Summary of negative comments from individual speaker evaluations# Comments#SpeakersPoor content107 (12.4%)51 (63%)Poor delivery74 (8.6%)31 (38.3%)Poor image slides72 (8.4%)19 (23.5%)Poor English58 (6.7%)9 (11.1%)Poor text slides37 (4.3%)26 (32%)Poor handout19 (2.2%)14 (17.3%)Other37 (4.3%)N/ATotal404 (46.9%)N/ANote: Percents shown represent percent of all comments (n=862) and speakers(n=81).Presentation skillsGelula [9] reported on aspects of voice clarity and speaking speed, approaches to using audiovisual aids, effectively using the audience as a resource, and ways to be entertaining as keys to effective lecturing. According to Gagne’s conditions of learning [10], it is first necessary to motivate and gain attention of the learner in order for learning to take place. When done properly, this aspect of the lecture offers a distinct advantage over written text or computerized programs. Van Dokkum [11] also offered suggestions for effective lecturing that included audience entertainment. He stated, "The two basic elements of a presentation are that it is both scientific and entertaining at the same time." Gigliotti [12] offered suggestions for developing an effective slide presentation, using novelty and humor. The author’s premise was that it will not matter how important the content of a presentation is if it is not heard due to lack of interest. For example, she suggested that a road sign reading "Gas Next Exit" would attract more interest from the audience than a slide that reads "Abdominal distention."In another study, Copeland et al [13] collected data from physicians participating in lecture-based CME internal medicine courses to determine the most important features of the effective lecture. These features were clarity and visibility of slides, relevance of material to the audience, and the speaker’s ability to identify key issues, engage the audience, and present material clearly and with animation. Features determined least likely to affect the attendee’s ratings of a lecture included presenter’s age, gender, physical appearance, and time of day in which the lecture was delivered.Features of effective presentationsFrom evaluation of speakers at the STR Course and the educational literature, specific features of effective presentations were identified. The list of features can be used as a checklist by persons wanting to improve the quality of their presentations and can be used by persons evaluating speakers.Slides•Make images with optimal contrast resolution (not too light or too dark).•Make images big enough to be seen by everyone in the audience, including those in the back of the room.•Use enough images to illustrate the important points of the presentation, with the appropriate number of text slides relative to image slides.•Keep slides simple, avoiding too many lines per slide (>6), too many characters per line, lines extending too inferiorly on slide, distractinganimation effects, and too many graphs.•Use color schemes that optimize visualization of the text, avoiding schemes that make the text difficult to read (i.e. purple or red on green).•Check slides for grammar and spelling errors prior to presentation.Content•Provide an appropriate, limited amount of data that is needed to support the findings and conclusions without overloading the audience with too manystatistics, charts or graphs, or making assumptions without providingsupportive data.•Provide content that is up-to-date and relevant to current practice.•Present content in an unbiased fashion without showing favoritism to one or more companies/institutional protocols when there are acceptable alternatives that the audience should be familiar with.•Follow the printed program and objectives.•Present content that is practical and appropriate for the audience, not too simple or complex or irrelevant to the listeners.•Incorporate appropriate humor or anecdotes into the presentation to engage the audience.Delivery•Vary voice inflection, speaking in a conversational tone rather than a monotone voice.•Speak at an appropriate pace, not too fast, and incorporate pauses into the presentation.•Slow down or pause when showing cine images so that the audience can see the pertinent findings.•Use the slides to emphasize key points, without reading the slides word-for-word.•Speak with enthusiasm, showing interest in the topic and regard for the audience’s interest.•Speak loudly enough that everyone in the audience, especially those in the back of the room, can hear.•Speak clearly and consider rehearsing in front of an appropriate audience, if speaking in a less familiar language than the presenter’s primary language.•Follow time limits.•Incorporate interaction into the presentation, such as asking the audience questions (rhetorical or otherwise), directing the audience to think of orperform a specific task, using case-based examples, or using an audienceresponse system.•Use appropriate gesturing and facial expressions and avoid being a dull, immovable object.•Speak directly into the microphone, even when turning head or moving away from the podium.•Use a laser pointer/cursor to point out or emphasize important features on a slide, avoiding random, distracting movement.•Rehearse the presentation in order to be completely familiar with the content and organization of the slides.•Be familiar with the audiovisual equipment and how to obtain assistance if needed.•Speak professionally and with confidence, without being apologetic for the content or appearance of slides.References1.Newble D, Cannon R.

Lecture 8
1. Power system stability may be broadly defined as that property of a power system that enables it to remain in a state of operating equilibrium under normal operating conditions and to regain an acceptable state of equilibrium after being subjected to a disturbance. 电力系统稳定性可以广泛定义为电力系统的一个特性,即 在正常工作条件下保持运行平衡状态,在受到干扰以后可 以重新回到可接受的平衡状态。 2. Since power system rely on synchronous machines for generation of electrical power, a necessary condition for satisfactory system operation is that all synchronous machines remain in synchronism or, colloquially, “in step”. 既然电力系统依靠同步电机发电,系统正常运行的一个必 要条件是所有的同步电机保持同步,通俗一点讲就是“步 调一致”。 6

Lecture 8(2)
April 28, 2011 Lecture 8Education(2)Higher learning stage in U.S.A.Various forms of educationPrimary/elementary SchoolsGrammar and high schoolsPublic (state owned)/private College or UniversityV ocational higher education- community collegeLife time study in U.S.A.In U.S. everyone must study for lifetime without age limit to keep in touch with the changing life around him/her. Americans are proud of the fact that the window of knowledge is never closed for the nation’s citizens.Studying abroadStudying abroad brings many advantages as well as many new experiences. Many aspects of university life are vastly different to those in a student’s country of origin. Conditions, academic expectations and requirements, social life and study schedule all can be a far cry from what students have already experienced at home.Being aware of and understanding some of the main differences can mean that the cultural shock is lessened and that it is easier to adjust to new ways of study. American universityAmerican universities have no entrance exam. A bachelor’s degree requires about 36 courses.Every course that student take is given certain credits.When he/she gets the required credits, he/she receives Bachelor’s degree. Degree systemBachelorIt usually takes four years to complete the courses required for a Bachelor of Arts or Bachelor of Science(B.A.) degree.MasterA Master of Arts or Master of science (M.A) needs one or two additional years of study.DoctorDoctor of philosophy(PH.D.) may take any number of years to complete. College grades(evaluation)system College grades, from highest tolowest, run A, B, C, D, F. (equal to 5, 4, 3, 2, 1 )A-: 4.8—4.4,B+: 4.5—4.1,B: 4,B- : 3.8—3.4,C+: 3.5—3.1,C : 3Generally speaking, you must have your average score above C that you have the chance to keep your right to study at college. To have the qualification to apply scholarship, you must have your average above B+.An F is a failing grade; if a student receives an F, he does not get credit. College students must maintain at least a low c average in order to remain in school. Financial sources for students:1.Loan from government2.(student)Scholarship3.Support themselvesAttitudes towards educationAmericans as a whole shows much respect for education, although teachers are not among the highest paid in the country.All traffic, for example, has to stop and make way for school bus.Study approachFor some students, the biggest difference is the way of study, and with less emphasis on teacher’s input, a greater expectation for students to be more independent in their thinking, especially in the application of critical analysis.Western education, from the early stages trough to post-graduate study,encourages the student to analyze, constructively criticize and to provide alternatives. That requires a special set of skills and, when combined with problem solving skills, it becomes obvious that students who study overseas must learn new skills and apply them to survive in the competitive world of academic study.Often the overseas student is strong at memorization but, by and large, rote(死记硬背)learning is regarded as a relatively basic skill in western education systems. There is a greater emphasis on the need for critical thinking and students who intend to study abroad should ensure that their critical thinking and analytical skill are well developed.Study scheduleIn many senses, for both undergraduate and post graduate studentsthere are significant differences in the arrangements for study at a western-style university.The main differences :1. There is a great variety of subjects to choose from. This means that careful research should be done as to what subjects should be chosen each term / semester.2. It is possible to change courses but that is usually only possible within a few weeks once the term has started.3. There are fewer lectures to attend per week (e.g. three separate hours for one course).4. Attendance is expected but not checked(a roll is not usually taken for lectures) – it is the responsibility of the student, who as an adult, must ensure that the appropriatework is completed and knowledge learned.5. Students are expected to question the lecturer and even to debate issues.6. There is less organization of students. In many countries, students come and go as they please. There is less obligation for them to be at a particular place at a particular time.7. Students are expected to complete assignments and essays through their own study and discover, hence they need to spend ―free‖(non-lecture) time in the library.Seminar workSeminar presentations are the main type of learning approach used for post-graduate students at westernuniversity. Usually seminars last for two/three hours and at each one, a student or students present a well-researched paper and discuss aspects and issues. Sound presentation skills are necessary.In recent time, group research and group presentations have become a feature of post-graduate study.Approaches regarding the paper:1. Sometimes the paper is required to be handed out to the seminar participants two weeks in advance. This allows time for the students to research the topic and especially study the reference that the presenter has used for the paper.2. At other times the paper is handed out at the beginning of the seminar. Reference is made to it as the seminar proceeds.3. The paper is handed in for assessment. Assessment, however, is only one part of the evaluation. The other part is the actual presentation.4. It is important to note that the paper is usually not read to the participants- that is too easy.Extensions of time for assignments Sometimes it is necessary to ask for an extension of time to hand in the assignments. In general, tutors and professors are understanding, but the reason should be substantial.If there are questions about the course or any of the assignments, it is wise to make an appointment to talk with the tutor or the person in charge of the course. Do not let problems ride – fix them early.The issue of plagiarismPlagiarism or unauthorized copying of other people’s work is frowned upon in western academic institutions. Some overseas students encounter some problems, mostly because of misunderstanding. Often it is merely a cultural difference in that some students in their original countries are expected to use the ideas of certain authors and acknowledgement is understood but not stated in writing.In essence, it is expected that students will use their own ideas. If the ideas come from a particular author, it is vital that the author is acknowledged. This should be done even if the words of the original author have been changed. Several forms of acknowledgement :·a direct quotation·an indirect quotation·referring to the autho r·making an end note (or a footnote)It is advisable to read any of the advisory notes about plagiarism published by most universities. Help is usually available, especially for overseas students.Activities on campusOrientation week-- At the beginning of the academic year, an orientation week is held at which the various clubs and societies provide activities and opportunities for students to gain information. It is definitely worth the experience and it is a useful way of participating in the activities of the week. Students’Union-- In most tertiaryinstitutions, the Students’Union is a source of help and information. Students are expected to take advantage of the various services the union offers, since all students pay a fee for the union when they enroll. The students’union can provide information ranging from study to personal matters. They can direct you to appropriate contacts and assist with basic issues.Students clubs-- There are many clubs, associations, sporting and entertainment activities on campus. These are a great way to socialize and to make friends and it is useful to join at least one. It does help to keep the balance when studying hard.Some advices:If in doubt, ask-- Many aspects of study abroad are different and some of the requirements can be confusing. The best rule to apply is ask when you don’t know.Secretaries or receptionists of a department are always an excellent resource since they usually have a good understanding of what goes on in a department. Another useful source is the Students’Union, where students often go for information concerning all types of issues.Tutors can sometimes assist if the matter relates to an aspect of study or a course, but it is often difficult to find tutors and professors.It is also common practice to ask a student for assistance. In most cases, students are the one who know the details of ―what‖, ―where‖,and ―who‖and they are happy to share the information. It is often a useful way of making friends.Independence-- The style of study is different in so many respects in western countries. Students are expected to be far more independent in their learning and study.The reliance on textbooks is minimal andwide, independent reading and research is necessary.Reading lists are usually provided and students are required to locate and read the material. Hence, sound library skills are an essential.Most university libraries provide explanatory tours at the beginning of the academic year and these can be a source ofvaluable information for the new comer.Independent thinking requires critical analysis and for some students it is difficult to understand that critical thinking requires a different set of skills. To exercise critical analysis is not necessarily to be negative. Rather, by applying critical thinking is to sharpen, modify and make a concept or an idea even better. Western education encourages constructive criticism and therefore students are expected not only to what is said, but to think about possibilities and to argue and debate issues.。

Evaluating an IR system
Note: the information need is translated into a query Relevance is assessed relative to the information need not the query E.g., Information need: I'm looking for information on whether drinking red wine is more effective at reducing your risk of heart attacks than white wine. Query: wine red white heart attack effective You evaluate whether the doc addresses the information need, not whether it has these words
