现代英语语法的特点及学习方法
<<现代英语语法>>是高等教育自学考试英语专业语法课程的指定教材。
该教材借鉴了现代语言学界对英语语法的研究，力图从词、词组、分句、句子乃至语篇对英语语言的结构规律作一个较为系统的描写。
全书既讲理论，又重实践，既归纳了普遍的语言现象，又阐述了一些特殊的规律。
下面就简单介绍一下该书的语法体系与语法体系的差异，列举书中指出的一些特殊现象，并就学习者如何自学好英语语法提一些建议。
一．与传统语法体系的差异1. 主观规定与客观描写传统的英语语法以拉丁文法为基础，以书面语体、正式语体为研究对象，往往主观地规定一些规律同，结果，It's me. He is the man May talked about. 这样的句子均被认为是不地道的英语。
而现代英语语法不再进行硬性的、主观的规定，而是从活生生的语言出发，既研究书面语体、正式语体，也研究口语体、非正式语体，在此基础上，客观地描写语言的规律。
例如，关于主谓一致，书中介绍了三种原则：语法一致原则、意义一致原则和就近原则。
三种原则适用于不同的语体，语法一致原则是最基本的原则，意义一致原则一般用于非正式语体，就近原则往往适用于口语体(当然也有一些结构，如either…or, 即使在正式语体中也遵循就近原则)。
又如：与不定代词someone、anyone等照应的代词究竟是he还是they, 传统语法坚定地认为是he, 而现代语法却认为they也常见于非正式语体，也是一种正确的用法。
2.意义与形式传统语法较普遍地从意义角度归纳总结各种语法现象，动词时态的分类便是如此。
英语动词具有形态变化，不同的动词形式可以表示动作发生的时间，也可以告诉我们动作处于表达的时间来划分动词的动态，共划分出十六种时态。
要记清这十六种时态的名称已属不易，更不用说了解它们的形式、表达的具体意义或使用情况了。
现代英语语法试图理顺意义与形式的关系，对于动词形式的分类便结合了意义与形式两方面的内容，在时(tense)的基础上增加了另一语法范畴体(aspect)。
略谈现代英语语法与词汇的特点
略谈现代英语语法与词汇的特点
现代英语语法与词汇的特点有：
1、注重结构简洁、语言简明。
普通用语中，句型简洁、表达精炼，
采用简化语言结构；口语中，更加简洁，有大量简写句子和简写词语。
2、词汇的重组和重复使用。
词汇简洁，常重复使用强调，经常使用
双重否定表达含义，还有一些形式复杂的含义更加简单、明确的词语。
3、句子结构反映思维方式。
句子结构反映了使用者的思维方式和逻
辑思维，表现为时序关系、递进关系、复合关系等，使文章表达更加清晰。
4、多样化的表达方式。
英语语言中同一个概念可以有多种表达方式，有时候会重叠使用，有时候会拆分使用，使文章或者口语更加生动有趣。
Lesson 3专业英语基础-语法特点
depend upon the distance between them. 分子之间存在力的作用，这些力的大小取决于它们之间的距离
。
3.1.8大量使用非限定动词结构
主要的三种用法：
1） 表述一般叙述过程
As the electrons move, the surface charge density increases until the magnitude of theinternal field equals that of the external field, giving net field of zero inside the conductor.
而在科技英语中更为常见的是用来表示“工具、手段” Nowadays labs are built with large cranes and modern
equipment.
3.1.3并列成分的使用
在专业英语中，并列成分得到了大量的使用，下面的例句中都 使用了并列的成分:
The story of the quantum is the one of a confused and groping search for knowledge conducted by scientists of many lands on a front wider than the world of physics had ever seen before, illumined by flashes of insight, aided by accidents and guesses, and enlivened by coincidences such as one would expect to find only in fiction.
专业英语 语法
专业英语语法
专业英语语法和通用英语语法有很多相似之处，但也有一些差异。
以下是一些专业英语语法特点：
1. 名词化：在专业英语中，常用名词来代替动词或形容词，使句子更加简洁明了。
例如，用“mathematical model”代替“use mathematics to model”或“mathematical accuracy”。
2. 长句和复杂句：专业英语中常常使用长句和复杂句，以表达复杂的概念和逻辑关系。
因此，需要掌握更多的从句、修饰语和修饰词，以便清晰地表达思想。
3. 被动语态：在专业英语中，被动语态的使用比在通用英语中更为常见。
这是因为被动语态可以使句子更加客观，突出所要表达的信息，而不是强调动作的执行者。
4. 动词时态和语态：专业英语中常用一般现在时和一般过去时，而较少使用将来时和现在进行时。
此外，被动语态也是常用的语态之一。
5. 常用缩写和术语：在专业英语中，常用缩写和术语来表达复杂的概念和公式。
因此，需要了解和掌握相关的缩写和术语。
总之，专业英语语法在用词、句式结构、表达方式等方面都有自己的特点，需要多阅读、多写作、多实践才能掌握。

Effective communication is the cornerstone of success in both personal and professional life, and English grammar plays a crucial role in this process. In this speech, I will discuss the importance of English grammar, common grammar mistakes, and practical tips to improve your grammar skills.I. The Importance of English Grammar1. Clarity and precision: Proper grammar ensures that your message is clear and easy to understand. It helps you convey your thoughts and ideas effectively, avoiding misunderstandings and misinterpretations.2. Professionalism: In the workplace, good grammar reflects your professionalism and attention to detail. It demonstrates that you are capable of producing high-quality work and can be trusted to represent your organization.3. Confidence: When you are confident in your grammar skills, you can express yourself more freely and engage in conversations without worrying about making mistakes. This confidence can boost your self-esteem and enhance your communication skills.4. Access to opportunities: Good grammar can open doors to various opportunities, such as scholarships, job offers, and promotions. It can also help you stand out from the competition and increase your chances of success.II. Common Grammar Mistakes1. Subject-verb agreement: Many people struggle with subject-verb agreement, which requires the subject and verb to agree in number (singular or plural). For example, "She is" instead of "She are."2. Misuse of articles: Articles (a, an, the) are often used incorrectly, leading to confusion. For instance, "I have a dog" instead of "I have a dogs."3. Confusing homophones: Homophones are words that sound the same but have different meanings and spellings. Common examples include "there, their, and they're" or "your, you're, and your."4. Incorrect prepositions: Prepositions are used to show relationships between nouns, pronouns, and other words in a sentence. Many people make mistakes when using prepositions, such as "in" instead of "on" or "between" instead of "among."5. Split infinitives: A split infinitive occurs when there is a word or phrase inserted between the "to" and the "infinitive" verb. While it is not considered a grammatical error, some people believe it to be incorrect. For example, "to quickly leave" instead of "to leave quickly."III. Practical Tips to Improve Your Grammar Skills1. Practice regularly: Like any other skill, improving your grammar requires consistent practice. Dedicate time each day to review grammar rules and practice writing sentences.2. Read extensively: Reading books, articles, and other materials in English exposes you to different grammar structures and styles. Pay attention to how authors use grammar to convey their message.3. Use grammar resources: Invest in a good grammar handbook or downloada grammar app. These resources can provide you with explanations and examples of grammar rules.4. Write and proofread: Write short essays, stories, or emails and proofread them carefully. Pay attention to your grammar mistakes and correct them before submitting your work.5. Seek feedback: Share your writing with friends, family, or teachers to receive constructive feedback on your grammar usage.6. Join a study group: Studying grammar with others can provide motivation and accountability. You can also learn from each other's mistakes and discuss challenging grammar topics.7. Practice listening and speaking: Listening to native speakers and practicing your speaking skills can improve your understanding of grammar in context.In conclusion, mastering English grammar is essential for effective communication. By understanding the importance of grammar, being aware of common mistakes, and implementing practical tips to improve your skills, you can enhance your communication abilities and achieve your personal and professional goals.Thank you for your attention, and I hope this speech has been helpful in your journey towards mastering English grammar.。
讲课稿英语语法总结范文
讲课稿英语语法总结范文Grammar SummaryIntroduction:Good grammar is an essential tool for effective communication. It helps us convey our thoughts and ideas clearly, ensuring that our message is understood by others. In this grammar summary, we will cover the key principles of English grammar, including parts of speech, sentence structure, verb tense, and subject-verb agreement.Parts of Speech:1. Nouns: A noun is a word that represents a person, place, thing, or idea. It can be singular or plural, and it can be common or proper. Nouns are often the subject of a sentence or the object of a verb.2. Pronouns: Pronouns are words that replace nouns. They help avoid repetition and make sentences less clunky. Examples of pronouns include he, she, it, they, and us.3. Verbs: Verbs are a critical part of a sentence. They express action or a state of being. Verbs can be regular or irregular, and they can be in different tenses, such as present, past, or future.4. Adjectives: Adjectives are words that describe or modify a noun. They can tell us about the color, size, shape, or condition of an object. Adjectives usually come before the noun they modify.5. Adverbs: Adverbs are words that modify verbs, adjectives, or other adverbs. They add more information about manner, time, place, or degree to a sentence. Adverbs often end in -ly.6. Prepositions: Prepositions show the relationship between a noun or pronoun and other words in a sentence. They usually indicate location, direction, time, or manner. Examples of prepositions include in, on, at, and by.7. Conjunctions: Conjunctions are words that connect words or groups of words. They can be coordinating, subordinating, or correlative. Coordinating conjunctions include and, but, or, so, yet, and for.Sentence Structure:1. Subject and Predicate: Every sentence has a subject and a predicate. The subject typically performs the action or is the focus of the sentence. The predicate includes the verb and provides information about what the subject is doing or experiencing.2. Simple Sentences: A simple sentence consists of one independent clause. It expresses a complete thought and contains a subject and a verb. For example, "She runs every morning."3. Compound Sentences: A compound sentence consists of two or more independent clauses joined by a coordinating conjunction. For example, "I love to read, and my sister enjoys painting."4. Complex Sentences: A complex sentence consists of one independent clause and one or more dependent clauses. The dependent clause cannot stand alone as a sentence. For example, "Although she was tired, she continued working."Verb Tense:1. Present Tense: The present tense expresses an action that is happening now or regularly occurs. For example, "He walks to school every day."2. Past Tense: The past tense expresses an action that already happened. For example, "She traveled to Italy last summer."3. Future Tense: The future tense expresses an action that will happen in the future. For example, "We will have a party next week."Subject-Verb Agreement:1. Singular and Plural: The subject and verb must agree in number. Singular subjects take singular verbs, and plural subjects take plural verbs. For example, "He walks" (singular) and "They walk" (plural).2. Indefinite Pronouns: Indefinite pronouns, such as everyone, somebody, or each, are singular and require singular verbs. For example, "Everybody wants to go."Conclusion:Grammar provides the foundation for effective communication in English. Understanding the different parts of speech, sentence structure, verb tense, and subject-verb agreement allows us to construct clear and meaningful sentences. By mastering these grammar principles, we can improve our speaking and writing skills and ensure that our message is accurately conveyed.。

It is my great honor to stand before you today to discuss a topic that is often overlooked but plays a crucial role in our academic lives: the power of grammar. As students, we are constantly bombarded with information, assignments, and deadlines. However, amidst this chaos, the importance of grammar cannot be overstated. In this speech, I will explore why grammar is essential for academic success and how we can harness its power to excel in our studies.Firstly, let us consider the foundation that grammar provides for our written and spoken communication. Grammar is the set of rules that governs the structure and use of a language. It is the invisible thread that holds our sentences together, ensuring that our ideas are conveyed clearly and coherently. In academic settings, proper grammar is not just a matter of style; it is a reflection of our attention to detail and our commitment to effective communication.One of the primary reasons why grammar is crucial for academic successis its impact on our grades. Professors and instructors often grade assignments not only on content but also on form. A paper with impeccable grammar is more likely to receive a higher grade than one with numerous errors. This is because grammar demonstrates our understanding of the language and our ability to follow the conventions of academic writing. By paying close attention to grammar, we can ensure that our work is polished and professional, thereby increasing our chances of achieving good grades.Moreover, grammar is a vital tool for critical thinking and analysis. In academic writing, we are often required to present arguments, analyze data, and evaluate sources. Proper grammar allows us to do this with precision and clarity. For instance, when constructing a complex sentence, we must carefully select our words and arrange them in a logical order. This process encourages us to think critically about our ideas and to express them in a way that is both persuasive and coherent. In addition, understanding the nuances of grammar enables us to identifyerrors in our reasoning and to correct them before they undermine our arguments.Furthermore, grammar is essential for effective communication in the academic community. Whether we are collaborating with peers, presenting our research, or engaging in discussions, clear and grammaticallycorrect communication is key. When we communicate effectively, we are more likely to be understood, respected, and taken seriously. This is particularly important in fields where precision and clarity are paramount, such as science, engineering, and law.To harness the power of grammar, we must first recognize its importance and then take steps to improve our skills. Here are some strategies that can help us become more proficient in grammar:1. Read extensively: Reading books, articles, and other academic materials exposes us to a wide range of writing styles and grammar conventions. By analyzing these texts, we can learn how to construct sentences effectively and identify common errors.2. Write regularly: Writing practice is essential for mastering grammar. By writing essays, reports, and other academic assignments, we can apply what we have learned and refine our skills over time.3. Seek feedback: Don't be afraid to ask for help. Professors, teaching assistants, and even peers can provide valuable feedback on our writing. Use their suggestions to identify and correct errors that we might have missed.4. Use resources: There are numerous resources available to help us improve our grammar skills, such as grammar handbooks, online tutorials, and writing labs. Take advantage of these resources to enhance your understanding of the language.5. Be patient and persistent: Improving grammar skills is a gradual process that requires time and effort. Don't get discouraged by setbacks; instead, stay committed to your goal of becoming a proficient writer.In conclusion, the power of grammar cannot be underestimated. It is a fundamental aspect of academic success, enabling us to communicate effectively, think critically, and achieve our goals. By recognizing its importance and taking steps to improve our skills, we can harness the power of grammar to excel in our studies and beyond. Thank you for your attention, and may we all strive to become grammatically adept scholars.[Applause]。
