高二英语选修四知识点归纳选修四是高二英语的一门重要课程，主要涵盖了英语的语法、词汇、阅读及写作等方面的知识点。
下面将对选修四中的一些重要知识点进行归纳和总结。
一. 语法知识点1. 定语从句定语从句是修饰名词或代词的句子，通常由关系代词或关系副词引导。
在定语从句中，关系代词有that, which, who, whose, whom等，而关系副词有where, when, why等。
定语从句的作用是进一步说明或限定名词的意义。
在使用定语从句时要注意关系词的选择和位置，以及主从句的时态和语态保持一致。
2. 虚拟语气虚拟语气用于表达与事实相反、愿望、建议等情况。
虚拟语气的时态通常为过去时，常用的虚拟语气形式包括与过去事实相反的虚拟，如与过去事实相反的虚拟、与现在事实相反的虚拟、与将来事实相反的虚拟等。
在运用虚拟语气时，需注意条件从句和主句的相应时态。
二. 词汇知识点1. 同义词与近义词同义词是指义相同或相近的词语，如big和large，happy和glad。
而近义词指意义相近但不完全相同的词语，如house和home，begin和start。
掌握常见的同义词和近义词，可以提高阅读和写作的准确性和表达能力。
2. 词根、词缀和派生词词根是构成词汇的基本单位，它可以独立存在，也可以与其他词缀组合成新的词汇，如dict（说）和port（携带）。
词缀是附加在词根前后的字母或字母组合，可以改变词的词性或词义，如dis-（否定）、un-（不）、-ful（充满的）等。
派生词是由词根和词缀组成的新词，如dictionary（词典）和transportation（运输）。
三. 阅读理解知识点1. 主旨大意阅读理解中的主旨大意是指文章的中心思想或主要观点。
要准确抓住文章的主旨大意，需要综合考虑文章的标题、开头和结尾段落，以及重要信息点和关键词等。
在阅读理解中，找到主旨大意有助于更好地理解和答题。
2. 推理判断推理判断是根据文章所提供的信息，结合自己的常识和推理能力，进行逻辑推断和判断。
得夺市安庆阳光实验学校第12讲定语从句的4个易错点以及解题的3种方法备考指导定语从句是历年高考中考查的最多的一个考点，通常是以单项填空、语法填空、短文改错和书面表达的形式进行考查。
解决定语从句类题目通常使用的方法有：看是否是考查固定句型中固定用法，是否可以运用分析句式结构与句子成分来判断，是否可以运用句子中的某些特定的动词来判断，是否可以通过运用还原法来做出正确的判断。
一、定语从句的4个易错点易错点1as与which在定语从句中的区别正确判断找出先行词，看是否有“such”“the same”等词的修饰，是否翻译为“正如……”。
典例展示1 A lot of language learning, ________ has been discovered, is happening in the first year of life, so parents should talk much to their children during that period.答案as解析关系代词指整个一句话A lot of language learning is happening in the first year of life。
as用在句首，which用在句末，正确答案应该是as。
典例展示2We recommend that our human beings treat the nature with the same care ________ we give to our eyes.答案as解析先行词有the same修饰，其后定语从句则用that或as引导。
that表示同一个物，as表示同类中的一个。
根据题意可知应用as。
易错点2关系词在句中的作用判断失误定语从句中先行词为case, point, position, situation等词时，一定要确定它们在定语从句中所作的成分，如作状语，用关系副词where；作主/宾语时，用that或which。

从句知识点总结一、从句的概念。
从句是复合句中不能独立成句，但具有主语部分和谓语部分，由that、who、whom、when、why、where、how、which等引导词（Connective）引导的非主句部分。
它在整个句子中充当一个句子成分，如主语、宾语、表语、定语、状语等。
二、从句的分类。
1. 名词性从句。
- 主语从句。
- 定义：在复合句中充当主语的从句。
- 引导词：that（无意义，不充当成分，只起连接作用，但不可省略，在口语或非正式文体中that可省略的情况除外）、whether（是否）、if（是否，只能用于宾语从句，且不与or not连用）、连接代词（what、who、whom、which、whose等，在从句中充当主语、宾语、表语或定语）、连接副词（when、where、why、how等，在从句中充当状语）。
- 例如：That he will come to the party is certain.（that引导主语从句，位于句首时不能省略）- 注意：为了避免句子头重脚轻，常用it作形式主语，而将主语从句后置。
例如：It is certain that he will come to the party.- 宾语从句。
- 定义：在复合句中充当宾语的从句。
- 引导词：与主语从句基本相同。
- 例如：I don't know whether/if he will come.（whether和if都可以表示“是否”，引导宾语从句）- 注意：- 宾语从句要用陈述句语序。
例如：He asked me what my name was.（不能说He asked me what was my name.）- 当主句是一般现在时，宾语从句可以根据实际情况使用各种时态；当主句是一般过去时，宾语从句要用相应的过去时态（客观真理除外）。
例如：He said that he was reading a book at that time.（主句是过去时，从句用过去进行时）；The teacher told us that the earth goes around the sun.（“地球绕着太阳转”是客观真理，从句仍用一般现在时）- 表语从句。

七下英语二单元知识点Unit 2 of Grade 7 English covers a wide range of knowledge points that are essential for students to master at this stage of their language learning journey. From vocabulary expansion to grammar structures, this unit lays a solid foundation for further development in the English language.One of the key focus areas in Unit 2 is vocabulary building. Students are introduced to a variety of new words and expressions that are commonly used in everyday conversations and academic contexts. These include words related to hobbies and interests, as well as terms that describe different personality traits and emotions. By expanding their lexical repertoire, students can better express themselves and understand the nuances of the language.Another important aspect of Unit 2 is the study of grammar structures. This unit delves into the intricacies of the present continuous tense, which is used to describe actions that are currently in progress. Students learn to correctly form and use this tense, as well as understand the subtle differences between the presentcontinuous and the simple present. This knowledge is crucial for effective communication in both spoken and written English.In addition to the present continuous tense, Unit 2 also covers the concept of modals. Modals are auxiliary verbs that express different degrees of possibility, necessity, or obligation. Students explore the use of modals such as "can," "should," and "must," and learn how to apply them appropriately in various contexts. This understanding of modal usage enhances students' ability to convey their thoughts and opinions with greater precision.Unit 2 also introduces the concept of relative clauses, which are used to provide additional information about a noun or pronoun in a sentence. Students learn to identify and use relative pronouns like "who," "which," and "that" to create complex sentences that are more descriptive and informative. This skill is particularly important for academic writing, where the ability to construct well-structured and cohesive sentences is highly valued.Another key focus of Unit 2 is the development of reading comprehension skills. Students are exposed to a variety of text types, including narratives, informative articles, and dialogues. They learn strategies for understanding the main ideas, identifying key details, and drawing inferences from the given texts. This helps students become more proficient readers, which in turn supports their overalllanguage proficiency.In addition to reading comprehension, Unit 2 also emphasizes the importance of listening skills. Students engage in various listening activities, such as following instructions, identifying key information, and understanding spoken dialogues. This exposure to authentic language use helps students improve their ability to comprehend and respond to spoken English in real-life situations.Furthermore, Unit 2 encourages the development of speaking skills. Students participate in role-playing activities, group discussions, and individual presentations, which allow them to practice using the language they have learned in a more interactive and communicative setting. This hands-on experience helps students gain confidence in their ability to express themselves orally and engage in meaningful conversations.Finally, Unit 2 also touches upon the development of writing skills. Students are introduced to different types of writing, such as personal narratives, descriptive essays, and opinion pieces. They learn the basic structure and organization of these writing genres, as well as strategies for generating ideas, drafting, and revising their work. This comprehensive approach to writing instruction equips students with the necessary skills to communicate effectively in written English.In conclusion, Unit 2 of Grade 7 English is a comprehensive and multifaceted unit that covers a wide range of knowledge points. From vocabulary expansion to grammar structures, reading comprehension to listening and speaking skills, and the development of writing abilities, this unit lays a strong foundation for students to continue their English language learning journey. By mastering the content and skills covered in Unit 2, students will be better prepared to tackle more advanced language challenges and succeed in their academic and personal endeavors.。
七年级下册英语第二单元2d知识点：英语作为一门外语，需要我们不断地学习和掌握知识点。
今天，我们就来谈谈。
在这一部分中，我们需学习疑问词“when”和过去式的用法。
接下来，我们将分两部分讲解这两个知识点。
一、疑问词“when”“when”的基本意思是“什么时候”。
在句子中，它可以用来询问事情发生的时间，也可以用作从句中的关系词。
举个例子：1. When did you go to Beijing? (你什么时候去过北京？)2. I remember the day when we first met. (我记得我们第一次见面的那天。
)需要注意的是，当“when”的从句作为主语、宾语、表语、宾补或同位语时，我们需用it作为形式宾语。
例如：1. It surprised me when I heard the news. (当我听到这个消息时，我很惊讶。
)二、过去式过去式是表示发生在过去的动作或状态的时态。
在英语语法中，通常可以用简单过去式、过去进行时和过去完成时来表示过去的时间。
1. 简单过去式在简单过去式中，动词加上了-ed的结尾。
例如：1. I watched TV last night. (我昨晚看了电视。
)2. She answered the question correctly. (她正确地回答了问题。
)2. 过去进行时在过去进行时中，动词用was/were + V-ing的形式。
例如：1. At this time yesterday, she was riding her bike. (昨天这个时候，她正在骑自行车。
)2. They were playing basketball when it started to rain. (下雨时，他们在打篮球。
)3. 过去完成时在过去完成时中，动词用had + V-ed的形式。
例如：1. When she arrived home, she found that her parents had already gone out. (当她回家时，发现父母已经出去了。

2015年暑期补习知识点2 -- 从句从句，在我们所学的按句子结构分类的三种句子中只存在于复合句中。
一、回忆什么是复合句复合句(亦叫主从复合句)是由一个主句和一个或者一个以上的从句构成的句子。
复合句中的主句和从句都具有完整的主谓结构。
主句是复合句的主体，可以独立存在。
从句需要有一个连词引导与主句连接在一起，是修饰说明主句的，不能独立存在。
根据在句中不同的作用，从句可以分为三大类：名词性从句（主语从句，表语从句，宾语从句和同位语从句）、形容词性从句（定语从句）和副词性从句（状语从句）。
从句名词性从句主语从句表语从句宾语从句同位语从句形容词性从句定语从句限制性定语从句、非限制性定语从句。
副词性从句状语从句时间状语从句、地点状语从句、原因状语从句、目的状语从句、方式状语从句、条件状语从句、结果状语从句、让步状语从句、比较状语从句等。
二、名词性从句1）主语从句：一个从句在复合句中充当主句的主语，通常放于主句谓语动词之前。
可以引导主语从句的关联词有：that, whether, what, which, whom, whose, when, where, why, how, whatever, whoever...That he will succeed is certain.Whether she will go there is not known.What he said is not true.Who broke the window has not been found out.How he escaped is still a mystery.That Mr. Brown can’t attend our English meeting is a pity.深化点拨：（1）that引导主语从句时，无实际意义，不作句子成分，但不能省略。
（2）主语从句中，为保持句子的平衡，避免头重脚轻，我们常用it作形式主语代替主语从句，而把真正的主语至于句尾。
It is a pity that Mr. Brown can’t attend our English meeting.2）宾语从句：一个句子在复合句中充当主句的宾语。
