小学英语语法详解陈述句--肯定句、否定句

小学英语语法详解陈述句——肯定句什么是陈述句？陈述句陈述一个事实或者说话人的看法。

它包括肯定句（The Affirmative Sentence）和否定句（The Negative Sentence）两种。

陈述句在书写时句末用句号，在明读时用降调。

一.肯定句基本结构为“主+谓"结构以及它的补充结构，以下是常用的几种肯定句。

1.主语+be动词（am/is/are）+表语He is tall.他很高。

They are honest.他们是诚实的。

Aaron老师的小提醒这里的be动词（am/is/are）也可变成其他的系动词。

I feel better.我感觉好多了。

The leaves turned yellow.叶子变黄了。

2.主语+谓语（不及物动词）The bell rang.铃声响了。

The match begins.比赛开始了。

Linda老师的小提醒当谓语动词是不及物动词的时候，虽然后面不可以跟宾语，但是可以跟状语用来修饰。

The car goes fast.车子跑得很快。

My grandpa walks slowly.我爷爷走路很慢。

3.主语+谓语（及物动词）+宾语+（状语）He wrote a letter yesterday.他昨天写了一封信。

I give him a hug.我给他一个拥抱。

5.主语+谓语（及物动词）+宾语+宾语补足语I painted it yellow.我把它涂成黄色。

I made her cry.我把她弄哭了。

Aaron老师的小提醒这五种基本句式结构只限于简单句，也就是只包含一个谓语结构，而不包括并列句和复合句。

肯定句和否定句的英文教学教案

肯定句和否定句的英文教学教案Title: English Teaching Lesson Plan - Teaching Affirmative and Negative SentencesIntroduction:This English teaching lesson plan aims to provide a comprehensive approach to teaching students the concept and usage of affirmative and negative sentences in the English language. The lesson plan is designed for intermediate-level students and incorporates various engaging activities and exercises to enhance their understanding and proficiency in forming and using these types of sentences.I. Learning Objectives- Understand the definition and characteristics of affirmative and negative sentences.- Identify the differences between affirmative and negative sentence structures.- Accurately form affirmative and negative sentences.- Apply the knowledge of affirmative and negative sentences in practical language situations.II. Warm-Up Activity: Sentence SortBegin the lesson by engaging students in a warm-up activity to activate their prior knowledge and introduce the concept of affirmative and negative sentences.- Provide a set of sentence cards, each containing either an affirmative or negative sentence.- Ask students to work individually or in pairs to categorize the sentences into two groups: affirmative and negative.- Discuss the correct categorization as a class, highlighting the key features of each sentence type.III. Explanation and ExamplesProvide a clear explanation of the characteristics and structures of affirmative and negative sentences, along with relevant examples.1. Affirmative Sentences:- Affirmative sentences state something as true or confirm a fact.- Structure: Subject + Verb + Object/Complement.- Examples: "She enjoys playing the piano." "They have completed their homework."2. Negative Sentences:- Negative sentences express the negation or denial of a fact.- Structure: Subject + Auxiliary Verb (e.g., do/does/did) + NOT + Main Verb + Object/Complement.- Examples: "He does not like spicy food." "We did not go to the cinema."IV. Guided Practice: Sentence TransformationIn this activity, students will practice transforming affirmative sentences into negative sentences and vice versa.1. Transforming Affirmative to Negative:- Provide a set of affirmative sentences, either written or projected.- Ask students to work individually to transform each sentence into its corresponding negative form.- Encourage students to pay attention to the correct placement of auxiliary verbs and 'not.'- Discuss the correct answers as a class, clarifying any doubts or difficulties encountered.2. Transforming Negative to Affirmative:- Provide a set of negative sentences.- In pairs or small groups, students should rewrite each sentence into an affirmative form.- Emphasize the need to use appropriate auxiliary verbs and adjust the sentence structure accordingly.- Review the transformed sentences together, ensuring accuracy and understanding.V. Application: Role PlayEngage the students in a role-play activity to practice the usage of affirmative and negative sentences in real-life situations.- Divide the class into pairs, assigning each pair a scenario where they must use appropriate affirmative and negative sentences.- Example scenarios could include ordering food at a restaurant, resolving a conflict, or discussing travel plans.- Encourage students to actively use the target sentence structures in their conversations.- Monitor and provide feedback on their language usage and accuracy.VI. Consolidation: Error CorrectionTo reinforce the learning, students will be presented with a series of sentences containing errors in affirmation and negation.- Provide a handout or project the sentences for the whole class to see.- In pairs or individually, students should identify and correct the errors in each sentence.- Discuss and review the corrections together, explaining the reasoning behind the changes made.VII. Wrap-up: Recap and ReflectionSummarize the key points covered in the lesson, emphasizing the usage and formation of affirmative and negative sentences. Allow students to ask any remaining questions or seek clarification.- Engage in a class discussion or reflective writing activity, where students share their thoughts on the lesson and express their confidence in using affirmative and negative sentences.- Provide constructive feedback and positive reinforcement.VIII. Homework AssignmentAssign homework tasks that involve further practice in forming and using affirmative and negative sentences. This could include completing worksheets, writing short paragraphs, or engaging in online learning platforms.Conclusion:This English teaching lesson plan offers a structured and engaging approach to teaching affirmative and negative sentences. By incorporating various activities, such as sentence sorting, sentence transformation, role-play, and error correction, students will have ample opportunities to develop their understanding and proficiency in using these important sentence types. Through targeted practice and application, students will gain the necessary skills to confidently communicate using affirmative and negative sentences in English.。

学生姓名考核内容陈述句（肯定句与否定句）、反问句难度系数中家长签名授课老师范老师

授课时段剩余课时成绩一．陈述句的概念：是陈述一个事实或者说话人的看法,陈述句分为肯定句和否定句。 1.肯定句的概念：对事物做出肯定判断的句子叫做肯定句.例如：他是一名好学生。 2.否定句的概念：对事物做出否定判断的句子叫做否定句。例如：他不是一名好学生 3.肯定句与否定句之间的转化原则：（1）不能改变原意。（2）肯定句改为否定句时，要加两个否定词，否则就改变了原意。例如：“我想去公园”。改为否定句，要加两个否定词，“我不是不想去公园”（没有改变原意），如果只加一个否定词，则变为“我不想去公园”（改变了原意）。二．反问句的概念：反问句就是用疑问的句式，表达肯定的观点。反问句表面看来是疑问的形式，但实际上表达的是肯定的意思，答案就在问句之中。反问的形式比一般的陈述句语气更强，更能引起人们的思考。例如：难道你就不想去吗？。基本结构：反问语气词+主语+肯定词/否定词+宾语+疑问助词+问号。 1.陈述句改反问句：（1）将肯定句中的肯定词（是、能、会等）改为否定词（不是、不能、不会等）。（2）将否定句中的否定词（不是、不能、不会等）改为肯定词（是、能、会等）。（3）在肯定词或否定词前面加上“怎、怎么、难道、岂”等反问语气词。（4）句尾加上疑问助词“呢、吗”等，句末的句号改为问号。例如：雷锋叔叔是我们学习的榜样。在改反问句时，将肯定词“是”改为否定词“不是”，在句首加上“难道”，句尾加上“吗”，句末的句号改为问号。这样，改成的反问句是：难道雷锋叔叔不是我们学习的榜样吗？ 2.反问句改陈述句：（1）将反问句中的肯定词改为否定词，或将否定词改为肯定词。（2）将反问句中的反问语气词（怎、怎么、难道等）去掉。（3）将句末的疑问助词（呢、吗等）去掉，问号改为句号。例如：我们怎能言而无信呢？在改为陈述句时，将“能”改为“不能”，去掉“怎”，将“呢”去掉，问号改为句号。所改成的陈述句是：我们不能言而无信
