(完整版)初中英语从句语法讲解
从句从句按其在复合句中的作用,分为主语从句、表语从句、宾语从句、定语从句和状语从句等。
（参见以下各条）3、各从句在句子中的位置以及用法：(1) 表语从句：在句子中作连系动词的表语的从句,它位于主句中的系动词之后。
例如：That is why he did not come to school yesterday. / It is because you are so clever.(2) 宾语从句：在句子中作及物动词或介词的宾语。
①基本形式：（主句＋）连词+从句主语+从句谓语+...②关于宾语从句连词的选择：若从句来源于一个陈述句,那么,连词用that,在口语中that可以省略;若从句来源于一个一般疑问句,连词则用if 或whether;若从句来源于一个特殊疑问句,则连词就是疑问词(如what,who,where,when等)例如：They believe that the computer will finally take the place of human beings.(他们相信计算机终将代替人类。
) (从句本来就是陈述句)/ I wonder whether I should saysomething for him to the headmaster. (我不知道是不是该为他在校长跟前说点什么。
) (从句来源于一般问句Shall I say something for him to the headmaster?)/ He asked mewhere he could get such medicine. (他问我在哪儿能搞到那样的药。
) (从句来源于特殊问句Where can he get such medicine? )③宾语从句的时态问题：如果主句是现在时,从句则用现在某一时态,甚至可以用过去时；如主句是过去时,从句则相应地使用过去某一时态,遇到客观真理时仍然用现在时。
如：I think Iwill do better in English this term. (我想本学期我的英语会学得好点。
状语从句讲义(讲稿)
状语从句状语从句在高考试题中由于其他从句的干扰，以及倒装句，强调句的介入，使得状语从句更为复杂。
状语从句是一种副词性从句，通常由一个从属连词或一个起连词作用的词组引导。
状语从句1. 时间状语从句常见的连词(组)：when, while, as, before, after, once, till, until, as soon as, now that, hardly ...when, scarcely ...when, no sooner ...than等。
可以引导时间状语从句的副（介）词（短语）或名词短语：directly, instantly, immediately, by the time, the moment, the second, the minute, the instant, every time, each time, next time, the last time等。
注意点如下：(1) when, while, as引导的时间状语从句as表示“当……的时候”，往往和when/ while通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。
when(at or during the time)既可以表示在某一点的时候，又可以表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。
while强调一段时间，仅表示从句和主句的动作同时发生，并且有延续意义，该从句中的动词一般要用延续性动词，从句中常用过去进行时态或一般过去时态；当when表示a period of time时，两者可以互换。
She came up as I was cooking.(同时) 在我做饭时，她走了过来。
When we were at school, we went to the library every day.(在一段时间内) 当我们在学校时，每天都去图书馆。
While they were watching TV, I was preparing myself for the coming examination.他们在看电视，而我在为即将到来的考试做准备。

高中英语定语从句说课稿范文大全
高中英语定语从句说课稿范文大全全文共3篇示例，供读者参考篇1Explaining Relative Clauses: A Guide for High SchoolersHey everyone! If you're like me, you might find some grammar topics a bit confusing at times. One area that has given me some trouble in the past is relative clauses. But don't worry, I'm here to break it down and explain them in a way that (hopefully) makes sense.What are Relative Clauses?A relative clause is a type of dependent clause that modifies or describes a noun or noun phrase. In other words, it gives us more information about the noun it refers to. Relative clauses are introduced by relative pronouns like "who," "whose," "which," "that," and sometimes "when" or "where."For example:"The book that I read last night was really interesting."In this sentence, "that I read last night" is the relative clause modifying and giving more details about "the book."Types of Relative ClausesThere are two main types of relative clauses: restrictive (defining) and non-restrictive (non-defining).Restrictive Relative Clauses:These clauses are essential to the meaning of the sentence because they specify which noun you're referring to. They are not set off by commas.Example: "Students who study hard tend to get better grades."The clause "who study hard" is restrictive because it identifies a specific group of students.Non-Restrictive Relative Clauses:These clauses provide additional, non-essential information about the noun. They are set off by commas.Example: "My friend John, who loves reading, just got a new book."The clause "who loves reading" is non-restrictive because it just gives extra details about John.Relative PronounsAs mentioned, relative clauses are introduced by relative pronouns like:Who/Whom - for peopleWhich - for thingsWhose - for possessionThat - for things or people (in restrictive clauses)Examples:"The girl who won the race is my neighbor.""The laptop which I bought last year is really fast.""The man whose car was stolen called the police.""The book that I read was a classic."Sometimes the relative pronoun is omitted, especially when it would be the object of the relative clause:"The book (that) I read was a classic."Prepositions in Relative ClausesWhen a preposition is used with a relative pronoun, there are two options:Place the preposition before the relative pronoun:"The person to whom I gave the book was grateful."Place the preposition at the end (this is more common):"The person whom I gave the book to was grateful."Summing It UpRelative clauses allow us to combine sentences and provide more details about nouns. Just remember the two types (restrictive vs non-restrictive), the different relative pronouns, and how to use prepositions. With some practice, they'll become much easier!I hope this guide has helped explain relative clauses in a clear way. Let me know if you have any other grammar questions - I'm always happy to lend a hand to my fellow students!篇2Title: The Wonderful World of Adjective ClausesHello everyone! Today we're going to dive into the fascinating realm of adjective clauses, also known as relative clauses. These little gems are like superheroes in the English language, giving us the power to describe nouns in more detail. Get ready to unlock a whole new level of descriptive prowess!What are Adjective Clauses?Adjective clauses are groups of words that modify (describe) a noun or pronoun in a sentence. They provide additional information about the noun or pronoun, helping us paint a clearer picture in the reader's mind. Think of them as descriptive sidekicks, adding depth and color to our sentences.Here's an example:"The book that my friend recommended is a realpage-turner."In this sentence, "that my friend recommended" is an adjective clause modifying the noun "book." It tells us which specific book we're talking about – the one that was recommended by the speaker's friend.Types of Adjective ClausesThere are two main types of adjective clauses: restrictive and non-restrictive. Let's explore each one:Restrictive Adjective ClausesThese clauses are essential to the meaning of the sentence because they help identify the specific noun or pronoun being described. Without these clauses, the sentence would be incomplete or unclear.Example: "The students who study hard usually get good grades."In this sentence, the clause "who study hard" is restrictive because it specifies which students we're talking about – the ones who study hard.Non-Restrictive Adjective ClausesThese clauses provide additional, non-essential information about the noun or pronoun. They're like little side notes, giving us extra details but not necessary for identifying the noun or pronoun.Example: "My sister, who loves to travel, is planning a trip to Europe."Here, the clause "who loves to travel" is non-restrictive because it's just an extra detail about the speaker's sister. The sentence would still make sense without it.Punctuation with Adjective ClausesPunctuation plays a crucial role in distinguishing between restrictive and non-restrictive clauses.Restrictive clauses don't use commas:"The book that won the award was a bestseller."Non-restrictive clauses are set off by commas:"The Eiffel Tower, which was built in 1889, is a famous landmark in Paris."Pro Tip: If you can drop the clause and the sentence still makes sense, it's non-restrictive and needs commas. If the clause is essential for the sentence's meaning, it's restrictive and doesn't need commas.Relative Pronouns: The Gatekeepers of Adjective ClausesAdjective clauses typically start with relative pronouns, which act as gatekeepers, introducing and connecting the clause to the noun or pronoun it modifies. Here are the most common relative pronouns:Who/That (for people)Which/That (for things)Whose (for possession)Example:"The student whose essay impressed the teacher received a scholarship."In this sentence, "whose" is the relative pronoun introducing the adjective clause "whose essay impressed the teacher."Adjective Clauses in ActionNow that we've covered the basics, let's see some examples of adjective clauses in action:"The movie that we watched last night was a realtear-jerker.""The restaurant where we had dinner has amazing reviews.""The author whose books are bestsellers is coming to our city for a book signing."Can you spot the adjective clauses in these sentences? They're like hidden gems, adding depth and richness to our language.Practice Makes PerfectTo truly master adjective clauses, practice is key. Here are some exercises to try:Identify the adjective clauses in the following sentences:The car that my parents bought is energy-efficient.The library, which is open until 10 PM, is a great place to study.The scientist whose research was groundbreaking won a Nobel Prize.Combine the following sentences using adjective clauses:The book was a bestseller. The book was written by a famous author.My friend loves to travel. My friend is planning a trip to Europe.The restaurant has amazing reviews. We had dinner at the restaurant.Write your own sentences using both restrictive andnon-restrictive adjective clauses.Remember, practice makes perfect, and the more you use adjective clauses, the more natural they'll become in your writing and speaking.ConclusionAdjective clauses are like little descriptive gems, adding depth and richness to our language. By mastering these clauses, you'll elevate your communication skills and paint more vividpictures with your words. So, go forth and embrace the wonderful world of adjective clauses – your sentences will thank you!篇3Adjective Clauses: The Unsung Heroes of Descriptive LanguageHey everyone! Today, we're going to dive deep into the world of adjective clauses – those unsung heroes that add depth, detail, and richness to our descriptive language. Brace yourselves, because things are about to get grammatically intense!First off, what exactly are adjective clauses? Well, they're a type of dependent clause that modifies a noun or pronoun in the main clause. In other words, they're like little descriptive sidekicks that provide additional information about the noun or pronoun they're attached to. Pretty cool, right?Now, let's talk about the different types of adjective clauses. We've got two main categories:Restrictive Adjective ClausesThese bad boys are essential to the meaning of the sentence. Without them, the sentence would be incomplete or ambiguous.They're like the Batman to the noun's Bruce Wayne – the real identity can't exist without them.For example:"The book that won the Pulitzer Prize is a must-read."Without the clause "that won the Pulitzer Prize," we wouldn't know which specific book we're talking about.Non-restrictive Adjective ClausesThese guys are like the fun, quirky sidekicks of the grammar world. They provide additional information about the noun or pronoun, but the sentence would still make sense without them. Think of them as the Robin to Batman – nice to have around, but not entirely necessary.For example:"My sister, who loves to bake, brought homemade cookies to the party."The clause "who loves to bake" is just giving us some extra details about your sister, but the sentence would still be complete without it.Now, here's where things get really interesting: the punctuation rules! Restrictive adjective clauses don't usecommas to separate them from the main clause. They're integrated seamlessly, like a ninja blending into the shadows.Non-restrictive adjective clauses, on the other hand, are set apart by commas (or, in some cases, parentheses or dashes). It's like they're wearing a neon sign that says, "Hey, I'm just some extra info – no need to panic!"Here are a few examples to illustrate the difference:Restrictive: "The students who studied diligently passed the exam."Non-restrictive: "The students, who were all committed to their studies, passed the exam."See the difference? The restrictive clause specifies which students we're talking about, while the non-restrictive clause just provides additional (but non-essential) information.But wait, there's more! Adjective clauses can also be introduced by different relative pronouns, like "who," "whom," "whose," "that," and "which." These little guys act as placeholders for the noun or pronoun they're modifying, and they help connect the adjective clause to the main clause.For example:"The scientist whose research led to the breakthrough received a Nobel Prize."In this case, "whose" is the relative pronoun that introduces the adjective clause and refers back to "the scientist."Now, I know what you're thinking: "But what about those pesky situations where we need to modify a whole clause or phrase, not just a single noun or pronoun?" Fear not, my grammar-loving friends! That's where we bring in the big guns: adjective clauses with "where," "when," and "why."For example:"That's the cafe where we had our first date.""The moment when she scored the winning goal will forever be etched in my memory.""The reason why he chose that career path is still a mystery."In these cases, the adjective clauses provide additional information about the noun clauses "the cafe," "the moment," and "the reason," respectively.Phew, that was a lot of information to take in! But fear not, my fellow grammar enthusiasts – with practice and dedication, mastering adjective clauses will become second nature. Justremember to keep an eye out for those little descriptive sidekicks, and your writing will be elevated to new heights of clarity and sophistication.So, there you have it – a comprehensive guide to adjective clauses, straight from the desk of a grammar-obsessed student. Keep these rules in mind, and you'll be crafting sentences that are not only grammatically correct but also rich in detail and nuance.Now, go forth and conquer the world of descriptive language, one adjective clause at a time!。

英语从句大全 Ppt
• 试比较： • I will never forget the days that/which I spent in Beijing University. (本句days 作spend 的宾语， 故用关系代词that / which ) • I have never been to Beijing, but it’s the place that I most want to visit. (place 作visit 的宾语。)
• 如： • 1）We heard the news that he had won the game. 我们听到消息他赢得了 比赛。 试比较： • 2）We heard the news that he had told her. 我们听到他对她说的消息。 （定语从句） • 例2中的that从句的作用相当于一个形 容词，其作用是修饰the news；例1中 的that从句的作用相当于一个名词， 是对the news的进一步说明。 • 有时如果主句的谓语动词较短，为保 持句子平衡，避免头重脚轻，同位语 从句也常与要说明的名词分开。例如： Word came that he died yesterday. 消息传来说他昨天死了。
英语从句专四考点归纳
从句定义
• 所谓从句是指从属于主句的句子，由从属连词 连接。由主句和从句构成的复合句，是英语中 比较复杂的句子结构。从句的种类有很多，但 根据其性质和作用可以分为：名词性从句，形 容词性从句（即定语从句），副词性从句（即 状语从句）三大类。从句构成与用法的考查要 点很多，历来是专业四级英语考试试题的热点 与焦点，专业四级英语考试几乎每年都涉及到 对名词性从句、定语从句以及状语从句的考查， 常将并列连接词、从属连词、关系代词、关系 副词放在同一题干中进行考查，故意设置干扰 项，增加试题难度，以考查考生分析交际语境、 理解句子之间的逻辑关系的能力。
英语从句的讲解和例子
英语从句的讲解和例子英语从句分为名词性从句，形容词性从句（定语从句），以及状语从句。
例如结果状语从句：He was so angry that he couldn#39;t speak. 他气得话都说不出来。
从句体系包括：名词性从句（主语从句、表语从句、宾语从句及同位语从句）、定语从句、状语从句分类：从句不能单独成句，但它也有主语部分和谓语部分，是一个特殊句子，就像一个句子一样。
所不同在于，从句须由一个关联词引导。
根据从句语法功能的不同可分为：主语从句、表语从句、宾语从句、同位语从句、定语从句和状语从句6类。
前四类由于主语从句、表语从句、宾语从句及同位语从句在句子的功用相当于名词，所以通称名词性从句；定语从句功能相当于形容词，称为形容词性从句；而状语从句功能相当于副词，称为副词性从句。
状语从句还可以分为条件状语从句、原因状语从句、地点状语从句、目的状语从句、让步状语从句、比较状语从句、方式状语从句、结果状语从句和时间状语从句。
主语从句（Subject Clause）用作主语的从句叫主语从句。
引导主语从句的关联词有从属连词、疑问代词、疑问副词、缩合连接代词、缩合连接副词等。
表语从句（Predicative Clause）用作表语的从句叫做表语从句。
引导表语从句的关联词与引导主语从句的关联词很多都一样。
宾语从句（Object Clause）在句子中起宾语作用的从句叫做宾语从句.宾语从句分为三类：动词的宾语从句、介词的宾语从句和形容词的宾语从句。
同位语从句是名词性从句(主语从句、表语从句、宾语从句、同位语从句)中的主要从句之一，从句作同位语表示与之同位的名词(短语)的实际内容，它的作用相当于名词，对前面的名词(短语)加以补充说明或进一步解释，相当于一个表语从句，它们之间的关系就是同位关系，即主表关系。
定语从句是由关系代词或关系副词引导的从句，其作用是作定语修饰主句的某个名词性成分，相当于形容词，所以又称为形容词性从句，一般紧跟在它所修饰的先行词后面。

从句（复合句）作为语义上分清主次的手段，所谓从句（从属分句）就是把次要的思想内容置于结构上的从属地位，从而突出句子的主要思想。
即由一个主句和一个或一个以上的从句构成。
从句的方法有多种，可以有限定性从句、非限定性从句、无动词从句或只有词组表达的从句。
从句按语法功能主要分为名词性从句、关系（定语）从句和状语（条件）从句。
从句是英语专业四级考试语法项目中考核的重要内容。
考生要认真阅读下面的要点提示，以便顺利完成真题及相关试题的答题。
一、名词性从句要点提示名词性从句是在一个句子中起名词作用的主谓结构，它可以在主从复合句中作主语、宾语（包括介词宾语）、表语和同位语。
名词性从句的语序使用陈述语序。
1.主语从句、表语从句、和宾语从句a）从属连词that/whether/if只起连接作用，连接从句，不在从句中充当句子成分。
b）连接代词what（ever）/which（ever）/who(ever)/whom(ever)既连接从句，又在从句充当句子成分------如充当从句的主、宾、表语等。
c）连接副词when/where/how/why既连接从句，又在从句中作为副词充当从句的状语。
d）主语从句通常放在名首。
但为了保持句子的平衡，可用it作形式主语，而将主语从句由名首移至句末，即采用“It is+名词/形容词/分词+主语从句”的结构。
e）用that引导的宾语从句如果跟有补足语，须用形式宾语it，而将宾语从句放于宾语补足语之后，即采用“动词+it+宾语补足语+that从句”的结构。
f）表语从句用于系动词be/look/seem/remain之后，对句子主语进行解释和说明。
当句子主语为reason时，表语从句应当由that而不是because来引导，但可以说it/this/tha t is because……。
g）介词后面一般不能直接跟that引导的宾语从句，但以下几个介词除外，besides （that）/but(that)/except(that)/in(that)。
这些介词和后面的that已被当成固定的复合连接词使用。
h）动词doubt用于肯定顽抗到底式表示“怀疑”时，其后的宾语从句而whether或if引导，意为“是否……”；用于否定或疑问句时，其后的宾语从句用that引导。
i）连词whether和if都可引导名词性从句表示“是否”，但if的使用受到诸多限制：if不能引导表语从句、（位于名首的）主语从句、介词后的宾语或同位语从句等。
j）Whether后面可跟or或or not，其中or not既可紧跟在whether之后，也可分开放在句末或者省略，而if后面通常不接or not，如要接，则需与if分开放在后面。
k）动词不定式前只能用whether。
不能用if。
2.同位语从句a）在某些抽象名词后面常用连接词that，有时用whether引出同位语从句，具体说明这些名词的内容。
b）能接同位词从句的常用名词包括answer/belief/certainty/concept/conclusion/decision/discovery/doubt/evidence/explanation/fact/hope/idea/impression/information/knowle dge/law/likelihood/message/news/order/opinion/possibility/principle/probability/probl em/promise/proof/question/reply/report/rumor/statement/suggestion/thought/truth从句等。
c）在以下一些惯用结构中，也可以用同位语on the assumption that/on condition that/despite the fact that/on the grounds that/on the pretence that/on the supposition that/on the understanding that/with the exception that等。
为了句子结构平衡，同位语从句有时并不紧跟所修饰的名词，而是补谓语动词等其他的词隔开。
3.宾语从句a)部分及物动词和部分介词后面可以接宾语从句。
That引导宾语从句时，that在口语中常可以省略。
b)in/but/except/save少数几个介词后可接that引导的宾语从句，且已成为固定搭配。
c)在否定转移结构中，主句谓语动词表示“认为，相信，猜测”等，如果后面的宾语从句中含有否定词not,通常要将not移到主语谓语上。
这些词包括believe/consider/expect/fancy/guess/imagine/reckon/suppose/think等。
d)下列情况中，通常是从句中的谓语动词采用否定式：believe等(见c项)、前面带有副词或表示强调的助动词、与其他词构成并列谓语、不是以一般现在时出现以及作插入语时。
例1 Have you ever been in a siuation you know the other person is right yet you cannot agree with him?A.by whichB.thatC.in whereD.where【B】你是否经历过明知对方是正确的却不愿意同意其观点的场合呢？【答案解析】该题考察关系词的用法。
从该句结构看，这是一个同位语从句，先行词是siuation，故不难判断从句是对其内容作出具体的解释，此同谓语从句只能用that引导。
根据该句语义，可判定该从句是同谓语从句，而非定于从句。
因此[B]符合要求，为正确答案。
【选项解析】根据上述分析, [A]﹑[C]﹑[D]三个选项因一般不用于引导同位语从句，故均不符合要求。
二﹑关系(定语)从句要点提示1.引导定语从句的关系代词包括:who/whom/whose/which/that。
2.关系代词which/that/as引导的定于从句的用法a)关系代词在定语从句中作宾语时可省略。
b)先行词是不定代词时(all / any / anything / everything / few / little / much / none / nothing / some),关系代词不能用which，只能用that。
that在从句中作宾语时常省略。
c)先行词是anyone/anybody/everyone/everybody/someone/somebody时关系代词多用who或whom，不用that。
d)先行词被形容词最高级及first/last/no/only/very等修饰时，关系代词一般用that 而不用which/who/whom。
e)有两个或两个以上先行词兼指人或物时，关系代词用that。
f)先行词是集体名词时，指整体，关系代词用which；指集体中的各个成员，则用whog)whose引导定于从句，既可指人(用of whom替代)，又可指物(用of which替代)。
h)关系代词在定语从句中作介词宾语时，若该介词被提前，则关系代词不能省略，而只能用which/whom，不能用that/who。
3.介词＋关系代词的结构问题a)这些介词大多是定于从句中某个词或短语的习惯搭配，但有些固定短语动词不宜将借此分开前置。
b)此结构在定于从句中或单独做状语，或连同其他名词一起做状语。
c)“介词+whom/which+不定式短语作后置定语”结构，相当于一个定于从句。
此时若将介词还原后置，则必须省略whom/which，即成为不定式短语.d)表示部分所属关系的两种结构为：“名词(代词或数词)＋of whom”和“名词(代词或数词)＋of which”。
e)定于从句有时并不紧跟先行词，而是被一个介词短语隔开。
4.as引导定语从句的用法a)与as(so)/such/thesame连用，引导限制性定语从句。
b)as引导的非限制性定于从句与which引导非限制性定于从句有以下区别：*as引导的从句位置较为灵活，可位于主语前面﹑中间或后面；which引导的从句只能放在主句之后。
*as既可指前面提到的情况，也可指后面将要提到的情况；which只能指前面提到的情况。
*在某些习惯用法中，多用as，较少用which。
*as修饰整个主句；which既可修饰整个主句，也可修饰主句的一部分，或主句中的某一个名词或代词(先行词)*as后若为被动语态，被动语态中的be动词可以省略；which后的be动词在同样情况下则不可省略。
*as做主语时可以用除be以外的其他系动词作谓语，一般不用行为动词；which 则可用各类动词作谓语。
*从功能上看，as引导的定于从句往往表示一种附加说明；which引导的定语从句则为较重要的评说。
5.限制性定语从句和非限制性定于从句a)限制性定语从句和其先行词所指的意义有着不可分割的联系，缺少它，作为先行词的名词(词组)便不能明确表示所指对象。
非限制性定于从句和其先行词之间只有比较松散的联系，它不是先行词的不可缺少的组成部分，而仅仅是为先行词提供一些补充说明。
b)限制性定语从句在口语中前后没有停顿，在书写中一般不用逗号。
非限制性定语从句在口语中有停顿，在书写中常用逗号隔开。
c)当名词中心词带有表示类别的不定冠词时，其后的定语从句通常是限制性的。
d)当名词中心词带有前照应定冠词或带有all/any/every/some/no/等不定代词时，其后的定语从句也必定是限制性的。
e)非限制性定语从句一般情况下不能用that引导，而要根据情况用who/whom/whose/which引导，从句的关系代词作宾语是也不能省略。
f)which引导的非限制性定语从句可以修饰整个主句或主句的一部分。
g)关系副词where和when也能引导非限制性定语从句。
h)非限制性定语从句，就其意义来说，在句中有时相当于一个并列分句；有时在语义上起状语从句的作用，表示原因、目的、结果、条件、让步等意义。
6.关系副词when/where引导定语从句a)关系副词在定语从句中只作状语：why(for which)/where(at which)/when(on which)/when(during which)。
b)关系副词在定语从句中作状语时，要注意以下两点：一是先行词为表示“情况”的名词时(conditions,situation,instance等)，定语从句用where引导；二是how 不能用来引导定语从句。
7.同位语从句与定语从句的区别a)定语从句中的引导词既代替先行词，同时又在从句中作某个句子成分，作宾语时常可省略；同位语从句的引导词that在从句中不作任何成分，一般不可省略。
