苏版初二(下)英语：unit5语法篇(教师版)

苏版初二（下）英语：unit5语法篇（教师版）____________________________________________________________ __________________________________________________________________________________ ______________________学生通过本讲学习，能够掌握本单元的重点语法，并在综合能力上有一定的拓展。

when while 的区别和用法【一】while的意思是〝在……同时〔at the same time that )〞〝在……期间(for as long as, during the time that〕〞。

从while的本身词义来看，它只能表示一段时间，不能表示具体的时间点。

在时间上可以是〝线线重合〞或〝点线重合〞，但不能表示〝点点重合〞。

例如：1、He was watching TV while she was cooking. 她做饭时，他在看电视。

〔线线重合〕2、He was waiting for me while I was working. 我工作的时候，他正等着我。

〔线线重合〕3、He asked me a question while I was speaking. 我在讲话时，他问了我一个问题。

〔点线重合〕【二】when的意思是〝当……时候〔at the time that〕〞〝无论什么时候〔whenever〕〞〝一……就……〔as soon as 〕〞〝在……以后〔a fter〕〞。

它表示的时间概念比较广泛，上述例句中的as或while均可用w hen代替，因为when不但可以表示具体的时间点，而且也可以表示一段时间。

在时间上它既能表示〝点点重合〞〝线线重合〞，又能表示〝点线重合〞。

例如：1、When he came in，she went out. 他进来，她出去。

八年级英语下册U5—U8语法归纳

八年级英语下册U5—U8语法归纳1 The Objective Clauses(宾语从句）①概念：在句子中起宾语作用的从句叫做宾语从句。

②宾语从句的三要素：连接词，语序，时态连接词：A.由that引导的宾语从句---注：that 在句中无词汇意义，在从句中不充当成分，在口语当中往往省略。

B.由从属连词whether, if 引导的宾语从句---if/whether 引导宾语从句，表示“是否”之义，在句中不充当句子成份，if/whether可互换。

当句末为or not时，引导词只能用whether而不能用if.C.当宾语从句是特殊疑问句时，连接词就用原来的疑问词，但从句一定要注意用陈述语序。

语序：陈述句结构（主+谓+其他成分）时态：1.如果主句的时态是一般现在时，宾语从句的时态根据具体情况来确定，可以是任何时态。

2.如果主句的时态是一般过去时，宾语从句只能用相应的过去的时态（一般过去时，过去进行时，过去将来时，过去完成时）。

3. 如果宾语从句所陈述的是客观真理，即使主句用了过去时，从句仍用现在时态。

否定转移：在含有宾语从句的主从复合句中，当主句的主语为第一人称，谓语动词是think，believe, guess, suppose 等时，要将从句的否定词转移到主句中，即主句的谓语动词用否定式，宾语从句的谓语动用肯定式。

例1：汤姆说他想要和校长说话。

例2：没有人知道明天是否会下雨。

例3：我不理解他们为什么会如此的喜欢电脑游戏。

例4：你知道我们什么时候开运动会吗？例5：老师告诉我们地球围绕着太阳转。

例6：打扰一下，你可以告诉我我应该如何到达邮局吗？1.Exclamatory statements（感叹句）感叹句是表示赞美、惊叹、喜悦、等感情的句子，通常以what, how引导。

what修饰名词，how 修饰形容词，副词或动词。

①感叹句可由“what＋名词＋主语＋谓语……！”构成。

what引导的感叹句还可分为以下三类：A.What ＋a/an＋形容词＋可数名词单数！例7：他是一个多么聪明的小男孩啊!B.What＋形容词＋复数可数名词！例8：他们真是好学生！C.What＋形容词＋不可数名词！例9：今天天气多冷啊!②还有一类感叹句是由how引导，常有以下几类：A.How＋形容词＋……！例10：这个婴儿多么可爱啊!B.How＋副词＋……！例11：他工作多么努力啊!2.The usage of”used to”(used to 的用法)①used to 意为“过去常常”，可看作助动词或情态动词，其后跟动词原形，表示过去习惯或经常发生的动作或状态。

八下英语第五单元grammar知识点

八下英语第五单元grammar知识点全文共6篇示例，供读者参考篇1Title: Unleashing the Power of Grammar: Unit 5 Secrets Revealed!Ahoy, grammar adventurers! Brace yourselves for an exciting journey through the uncharted waters of Unit 5 in your Grade 8 English textbook. Get ready to hoist the sails and embark on a linguistic voyage like no other!First things first, let's talk about the mighty verb tenses. These little guys are the backbone of every sentence, telling us whether an action happened in the past, present, or future. Imagine you're a time traveler, hopping from one era to another. The verb tenses are your trusty companions, helping you navigate through the different time periods with ease.Speaking of time, let's dive into the past perfect tense. This tense is like a superhero cape that gives you the power to talk about actions that happened before a specific point in the past. For example, "I had finished my homework before my friendcalled." It's like rewinding a movie and hitting pause at the perfect moment!Now, let's turn our attention to the present perfect tense. This tense is a real globetrotter, allowing you to express experiences or actions that started in the past and are still relevant in the present. "I have visited many countries," you might say, as you proudly display your collection of souvenirs from around the world.But wait, there's more! The future perfect tense is a true visionary, helping you talk about actions that will be completed by a specific time in the future. "By the time the rocket launches, the astronauts will have trained for years." It's like having a crystal ball that lets you glimpse into the future!Next up, we have the tricky little rascals called modal verbs. These guys are like superheroes with special powers, adding shades of meaning to your sentences. "Can" expresses ability or possibility, while "must" emphasizes obligation or necessity. Imagine a superhero with the ability to fly and another who can move objects with their mind – that's the kind of versatility modal verbs bring to the table!Now, let's talk about the stealthy ninjas of grammar –passive voice. These sneaky sentences put the focus on theaction itself, rather than the doer. "The letter was written by the president" is an example of passive voice, where the action (writing the letter) takes center stage. It's like a magic trick where the magician disappears, and all you see is the floating card!Last but not least, we have the fearless warriors known as conditionals. These mighty sentences allow you to explore hypothetical situations and their potential consequences. "If I won the lottery, I would buy a private island." It's like having a secret portal that transports you to alternate realities!Phew, that was quite a linguistic odyssey, wasn't it? But fear not, grammar adventurers! With these powerful tools in your arsenal, you'll be unstoppable in your quest to conquer the English language. So, grab your grammar swords, put on your verb tense armor, and let's embark on new adventures together!篇2Grammar Buddies: Cracking the Code of Unit 5!Hey there, grammar gurus! It's me, your trusty Grammar Buddy, ready to take you on an exciting adventure through the world of grammar. Today, we're going to explore the fascinating realms of Unit 5 in our 8th grade English textbook. Get ready tounlock the secrets of grammar and become true masters of the English language!First up, let's talk about noun clauses. These little guys are like super-powered sentences that can act as subjects, objects, or even complements in a bigger sentence. They're introduced by words like "that," "what," "who," "which," and so on. For example, "What you said made me laugh" – see how "what you said" is a whole clause acting as the subject? Pretty cool, right?Next, we have adjective clauses. These bad boys describe nouns by giving us extra information about them. They usually start with relative pronouns like "who," "whose," "which," "that," or "where." For instance, "The book that I read yesterday was hilarious." The clause "that I read yesterday" tells us more about the book. Adjective clauses are like little detectives, gathering all the juicy details about nouns.Now, let's move on to adverb clauses. These fellas tell us more about verbs, adjectives, or even other adverbs篇3Grammar Galore: Mastering Unit 5 Like a Pro!Hey there, fellow grammar gurus! Are you ready to dive into the exciting world of Unit 5's grammar points? Get ready because this is going to be a wild ride filled with mind-boggling rules, tricky exceptions, and all sorts of linguistic awesomeness!First up, let's talk about those sneaky little things called "modal verbs." You know, words like "can," "could," "may," "might," and "must." These babies help us express all sorts of cool stuff, like abilities, possibilities, and even obligations. For example, "I can juggle three oranges" means you're a total rock star at fruit juggling. But "I must study for my test" means you better hit those books or else!Next, we've got the wonderful world of "conditionals." These are like magic spells that let us talk about hypothetical situations. Like, "If I had a million dollars, I would buy a candy factory." Dreamy, right? But conditionals can also be used for real-life stuff, like "If it rains, I'll bring my umbrella." See? Super handy!Alright, now let's tackle those "relative clauses." These suckers help us add extra details to our sentences, making them way more descriptive and interesting. For instance, "The book that I'm reading is really exciting" tells us way more than just "The book is exciting." It's like giving our sentences a tasty little garnish!Moving on, we've got "reported speech" or "indirect speech." This is how we share what someone else said without using their exact words. Like, instead of saying "Timmy said, 'I love chocolate cake,'" we can say, "Timmy said that he loved chocolate cake." Easy peasy, right?Last but not least, we've got "passive voice." This is when the object of a sentence becomes the subject, and the real subject kind of disappears. For example, "The cake was eaten by Timmy" instead of "Timmy ate the cake." It's like putting the spotlight on the cake instead of Timmy!Phew, that was a lot of grammar goodness, huh? But don't worry, we're not done yet! We still need to practice, practice, practice until these rules become second nature. So, let's dive into some fun exercises and activities to really cement these concepts in our brains.First up, let's play a game of "Modal Verb Madness." I'll give you a situation, and you have to respond with a sentence using the appropriate modal verb. For example, "You want to go to the playground, but it's raining." You could say, "I may go to the playground if it stops raining." See? Easy peasy!Next, let's tackle some conditional conundrums. I'll give you the first part of a conditional sentence, and you have to completeit. For instance, "If I won the lottery..." and you could respond with something like, "If I won the lottery, I would buy a million ice cream cones!"Now, let's play a round of "Relative Clause Relay." I'll start with a sentence, and you have to add a relative clause to it. Then, I'll add another relative clause to your sentence, and we'll keep going back and forth, making our sentence longer and more descriptive with each turn!For reported speech, we can play a game of "Telephone." I'll whisper a sentence to you, and you have to repeat it using reported speech. Then, you'll whisper the reported sentence to the next person, and so on, until we've created a hilarious chain of indirectly reported madness!Finally, let's tackle passive voice with a fun little activity called "Object Spotlight." I'll give you a sentence in active voice, and you have to rewrite it in passive voice, putting the object in the spotlight. For example, "The dog chased the cat" could become "The cat was chased by the dog."Alright, grammar geniuses, you've got all the tools you need to conquer Unit 5 like a boss! So, let's keep practicing, keep playing, and keep having fun with these incredible grammarrules. Before you know it, you'll be speaking and writing like a true linguistic master!篇4Grammar Gems: Mastering Unit 5 the Fun Way!Hey there, fellow grammar explorers!

It's me, your friendly neighborhood grammar guru, here to help you conquer the linguistic challenges of Unit 5 in our Grade 8 English textbook.Buckle up, because we're about to embark on a grammatical adventure that'll leave you feeling like a true wordsmith!Let's start with the big kahuna: the present perfect tense. Now, I know what you're thinking, "Present perfect? Sounds like a fancy schmancy way to talk about the present." Well, my friends, you're partly right. The present perfect tense is all about describing actions or events that started in the past but are still relevant or ongoing in the present. Think of it as a bridge between the past and the present, connecting the two in a harmonious linguistic dance.For example, let's say you've been studying English for years, and someone asks you, "How long have you been learning English?" You'd respond with, "I have been learning English for five years." Boom! Present perfect in action! See how it links the past action (starting to learn English) with the present (still learning it)? Nifty, right?But wait, there's more! The present perfect tense also comes in handy when you want to talk about experiences or achievements in your life. Imagine you're chatting with a friend, and they ask, "Have you ever been to Disneyland?" You can proudly proclaim, "Yes, I have been to Disneyland twice!" That'sthe present perfect tense working its magic, allowing you to share your past experiences in a present context.Now, let's move on to another grammatical gem: the present perfect continuous tense. This one's all about actions or situations that started in the past, are still ongoing in the present, and might continue into the future. Think of it as the present perfect's cooler, more dynamic cousin.Let's say you're working on a massive art project, and your mom walks in and asks, "What have you been doing?" You can reply, "I have been painting a mural for the school art show." See how the present perfect continuous tense conveys the idea that you started painting in the past, are still painting in the present, and might continue painting in the future? It's like a linguistic time machine, capturing the past, present, and future in one neat little package.But wait, there's more! We haven't even scratched the surface of the grammatical goodness that Unit 5 has to offer. Brace yourselves, because we're about to dive into the world of relative clauses!Relative clauses are like little descriptive ninjas, sneaking in extra information about nouns or pronouns to make yoursentences more detailed and interesting. They're introduced by relative pronouns like "who," "which," "that," and "whose."For example, let's say you're describing your favorite superhero. You could say, "Batman, who fights crime in Gotham City, is my favorite superhero." See how the relative clause "who fights crime in Gotham City" provides additional details about Batman? It's like a linguistic secret sauce, adding flavor and depth to your sentences.And let's not forget about the mighty gerund! Gerunds are verbs that have been transformed into noun-like creatures, often ending in "-ing." They're like the shape-shifters of the grammar world, able to take on different roles and functions within a sentence.Imagine you're chatting with a friend about your hobbies, and you say, "Swimming is my favorite way to exercise." In that sentence, "swimming" is a gerund, acting as the subject of the sentence. Gerunds can also be objects, like in the sentence "I enjoy reading books." Pretty versatile, right?Phew! That was a lot of grammatical goodness to take in, but don't worry, you're well on your way to becoming a Unit 5 master. Just remember, practice makes perfect, and before youknow it, you'll be wielding these grammar rules like a linguistic samurai.So, keep studying, keep practicing, and most importantly, have fun with these grammatical gems. After all, language is a beautiful tapestry, and each grammar rule is a thread that helps weave it together.
