英语词汇学怎么考 英语词汇学必背知识点

英语词汇学怎么考英语词汇学必背知识 点 英语词汇学考试难吗?那么该课程怎么考?要知道英语考试并不是一蹴而就的,所以考前应该日记月累的学习,在最后考试的时候才能更好的通过考试,我们来看看英语词汇学必背知识点吧。 英语词汇学怎么考 英语词汇学是一门理论知识课,每个知识点应该说都重要,所以重点和一般本来就难以界定。从掌握知识来说,不要去分重点和一般,对每章每节都要以搞懂弄通为原则。 1、考前重点词汇复习方法 要知道语法填空重点考查的词:动词、形容词、副词和派生词。其中重点是动词,要把考点的设置与拼写的可能形式结合起来(如从谓语动词的角度来看,就要 考虑动词的时态、语态和主谓一致所带来的动词变化。其中过去式是考查重点,所以对动词的过去式,尤其是不规则动词的过去式和过去分词的拼写,自然就成为后期复习的重点。至于另外三大词类也完全可以如此类推。
2、词汇积累学习

加强短文背诵,增强“词不离句”意识。背诵是非常原始的英语学习方法,但也是非常积极、有效的学习方法。优选一些名家名篇,做为背诵的素材;或从课文中精选一些精悍之作,作为研习的精典,不但能够迅速提高语感,而且容易激发兴趣,形成活生生的词库,为单词的准确使用打下良好的基础。 3、英语主观题拿分技巧 首先是单词拼写,这是所有题目中考生得分最低的一个部分,通常平均分不超过3分,所以大家不要太在意,20个单词,对4个,能有2分就很不错了,如果想要提高这部分,大家还要有准备的背单词,因为这里面的单词,并不全是课本课后单词表的单词,其中很多都是以前在中学学过的,所以要准备这一部分,需要的是买一本自考英语的词汇大纲,按里面的词汇背记才有意义。 如果大家对英语词汇学课程学习有难度,那么可以通过在线视频学习的,以上三点就是学赛小编对英语词汇学必背知识点学习方法,希望大家能更好的学习。 点击进入>>>

《演讲的艺术》chapter1-5课后summary

Chapter1 speakinginpublic People throughout history have used public speaking as a vital means of communication and empowerment. Because you will live the rest of your life in a globalized world, the need for English public speaking will almost surely touch you at some time. To be successful giving speeches in English, you need to be culturally competent communicator. You must show respect for the cultural values and expectations of the people who come to hear you. This dose not mean that you have to devalue your own culture. There is no inherent conflict between being a competent English public speaker and being fully Chinese. Because public speaking involves the use of English as a working language, it requires critical thinking skills. Critical thinking helps you organize your ideas, spot weaknesses in other people’s reasoning, and avoid them in your own. There are many similarities between public speaking and conversation, but there are also important differences. First, public speaking requires more detailed preparation than ordinary conversation. Second, it requires more formal language. Third, it demands that speakers adjust their voices to the larger audience and work at avoiding distracting physical mannerisms and verbal habits. The speech communication process includes seven elements: speaker, message, channel, listener, feedback, interference, and situation. The interaction of these elements determines the outcome of any public speech. Chapter2 speakingconfidentlyandethically stage fright is an issue for public speakers in all countries. Rather than trying to eliminate every trace of stage fright, you should try to transform it into positive energy. To some extent, this will happen naturally as you gain experience as a speaker, but you should also think positively, prepare thoroughly, visualize yourself giving a successful speech, remember that most nervousness is not visible to the audience, and think of your speech as communication rather than as a performance in which you must do everything perfectly Because public speaking is a form of power, it carries with it heavy ethical responsibili ties. There are four basic guidelines for ethical speechmaking. The first is to make sure your goals are ethically sound. The second is to be fully prepared for each speech. The third is to be honest in what you say. The fourth is to put ethical principles into practice at all times Of all the ethical lapses a speaker can commit, few are more serious than plagiarism lobal plagiarism is lifting a speech entirely from a single source. Patchwork plagiarism involves cutting and pasting a speech from a limited number of sources. Incremental pla giarism occurs when a speaker fails to give credit for specific quotations and paraphrases that are borrowed from other people Because it is so easy to copy information from the Internet, it poses special challenges with regard to plagiarism. If you don't cite Internet sources, you are just as guilty of plagia- rism as if you take information from print sources without proper citation. As you research your speeches, be sure to take accurate notes of the Internet sources you use so you can identify them in your speech Chapter3 giving your first speech One of your first assignments will be to present an introductory speech, either a speech of self-introduction or a speech introducing a classmate. Focus the speech on a limited number of ideas and be creative in developing them. Use interesting supporting materials and present them in colorful, descriptive language. When organizing the speech, make sure you have a clear introduction, body, and conclusion. Most introductory speeches fall naturally into chronological or topical order. Using clear transitions will help your audience follow you from point to point. Although you will write a complete manuscript or outline of your speech when preparing it, you should deliver it extemporaneously. This means you have rehearsed fully and can present your talk from a brief set of speaking notes. Concentrate on establishing eye contact with the audience and on speaking in a dynamic, engaged tonof voice Chapter4 selecting a topic and purpose The first step in speechmaking is choosing a topic. If you have trouble picking a topic, you can use clustering, a personal inventory, or an Internet search to come up with something that is right for you. The general purpose of your speech will usually be to inform or to persuade. When your general purpose is to inform, your goal is to communicate information clearly, accurately, and interestingly. When your general purpose is to persuade, your goal is to win listeners over to your point of view Once you know your topic and general purpose, you must focus on a specific purpose statement that indicates precisely what your speech seeks to achieve. The specific purpose statement should (1) be a full infinitive phrase; (2) be worded as a statement, not a question:(3) avoid figurative language;(4) not be vague or general; (5) be appropriate for your audience; and(6) be achievable in the allotted time. The central idea is a concise statement of what you will say in your speech, and it usually crystallizes in your thinking after you have done your research and have decided on the main points. In most cases, it encapsulates the main points in a single declarative
