高中英语课件必修3主语从句
主语从句讲与练一概念在复合句中充当主语的句子叫主语从句。
主语从句主要由that, 和wh-词引导。
二连接主语从句的连词1）that, whether（if）连接词that本身没有意义,不作句子成分, that不能省略；whether（if）尽管不充当句子成分,但是含有“是否”的意思,可以加上“or not”,其语意不变。
若主语从句位于句首或和or not 连用时,则必须用连接词whether, 而不用if。
Whether we'll go camping tomorrow depends on the weather.2）what, who（m）,which, whose, when, where, why, how在这一类连接词中,除引导主语从句外,在从句中分别起代词、副词或形容词的作用,在从句中分别作主语、宾语、表语、状语和定语。
因此,what,who（m）,which称为连接代词；when, where, why, how称为连接副词；whose, which, what称为连接形容词。
Who will do it doesn't matter.（连接代词who在从句中作主语）What we need is more water.（连接代词what在从句中作need的宾语）Which of the two is better remains to be see n.（连接代词which在从句中作主语）When we will start the work is an important questio n.（when在从句中作时间状语）Where the library is to be built has not been decided yet.（where在从句中作地点状语）Why she was late for school is quite clear now.（连接副词why在从句中作原因状语）Which plan is better will be announced later.（which在从句中作名词plan的定语）3）whatever, whoever, whomever, whicheverwhatever等连接词与what等连接代词的用法一样,只是具有较强的语意,有“凡是、不管、无论”等意思。

1 “主语从句”教学设计 【教材依据】 人教版高中英语必修三Unit 4 Astronomy：The Science of the Stars语法:主语从句 一、设计思路 1、指导思想 主语从句是高中英语中一个重要的语法项目，它在高考中占的比例中也是举足轻重的，在阅读，完型，语法填空，改错题中无所不在。尤其是作文中，学生如果能正确，漂亮地使用几个名词性从句，就能成 为其亮点和增分点。因此，我们要对它着重讲解。主语从句是在上一单元讲解了宾语从句和表语从句的基础上讲的，因此并不算太难。 2、教学目标 根据英语学科核心素养的要求，经过本课的学习，学生能够： （1）语言能力： a. 能辩认出主语从句。 b. 知道主语从句的三要素，正确使用主语从句。 c. 按句子所缺成分和意义正确使用主语从句的连接词。 d.能够学以致用，在平时的交流中能够用上名词性从句，真正达到其交际运用的功能。 （2）学习能力： 通过任务训练，培养学生的团队合作意识，提高学生互相学习、互相帮助的意识。 （3）文化意识 疫情相关例句的导入，让学生关注时事，知道只要坚定信心，就一定能取得成功，增强国家认同感，培养爱国情怀。 （4）思维品质 通过比较所获得的信息，能够归纳、概括其语法规律，并在实践中，用于处理解决新的问题。 3、教学重点与难点： a. 正确选择主语从句的连接词。 2
b. 在训练学生语言能力同时，注重培养学习英语的兴趣，培养学生的合作能力，提升学生的整体素质。 二、教学准备 教学设计、多媒体课件、导学案、彩色粉笔、活动用的卡片 三、教学过程 【一】预习检查 表扬激趣 1. 组长汇报预习检查的结果。 2. 导入：每组抽一名学生翻译预习案上的句子，检查预习效果，并通过主语来导入主语从句的定义。即： 主语是动作的 执行者 ，一般位于 谓语动词 之前。 在句子中，充当 主语 的从句，叫做主语从句。 3. 句式升级（简单句变复合句） (1) The news makes us anxious. (2) The number of COVID-19 cases worldwide has surpassed 200 million. 合并：That the number of COVID-19 cases worldwide has surpassed 200 million makes us anxious. 设计意图：让学生通过观察例句找出主语，明白主语不仅仅可以由名词、代词、不定式、动名词还可以由句子充当。从而自然而然自己归纳出主语从句的定义来。句式升级让学生进一步理解主语从句是对句子的润色，例句结合热点，提供情景能激起学生的兴趣。 【二】交流点拨 展示激趣 1. Find the subject clauses in the following sentences.（结对活动） (1) That the epidemic will be over is certain. (2) Whether it will please them is not easy to say. (3) Who will go makes no difference. (4) What we need is more time. (5) Which book I shall choose hasn’t been decided. (6) Whoever breaks the law will be punished. (7) When we will leave hasn't been decided. (8) Where the meeting will be held is not known. 3
(9) Why he cries is not clear. (10) Where she bought the book is unknown. 归纳小结： 1. 找出连接词。 2. 主语从句有哪些连接词？这些连接词是否充当成分？有无意义？
设计意图：让学生自己找出主语从句翻译后，自己观察归纳主语从句的连接词，再讨论其功能。由于已经学习了宾语从句，这部分学生归纳起来并不难。 这两个任务，我让学生课下自己做，批改后只把错误较多的在课堂上重点展示，这样只讲不会的，有疑问的，大大提高了课堂效率。 1. Fill in each blank with a proper conjunction.（小组活动） (1) (______the meeting will be held next week) hasn’t been decided yet. (2) (______the plan will be carried out) is unknown. (3) (______ team will win the match) is still unknown. (4) (_______ we need) is more time. (5) (________we can arrive at the airport before 8 o’clock) is still a question. (6) (_____the earth is a solid ball) is known to us all. (7) It is uncertain (________ side effect the medicine will bring about). 讨论： 1.核对讨论答案。 2. 连接词是怎样确定的？ 设计意图：本环节设计的1、2、5题答案都不唯一，可以引起学生们的争论，既活跃了课堂气氛又引发了他们的思考。完成这些习题后再通过两人合作讨论，归纳总结出本节课的难点：如何选用正确的引导词？这部分相对较难，同学总结的不是很到位为此，我作出了技巧点拨：运用三步“FAT”法，即：step1 find（找主语从句），step2 analyze（分析主语从句缺不缺成分），step3 translate（翻译整个句子,结合意思）。 【三】达标训练 评价激趣 1. 我要当老师（个人活动） 单句改错： 4
(1) He will give up his job surprises all of us. (2) If we will have a meeting hasn’t been decided yet. (3) Who will come to teach the students are not known. (4) That she wants to know is when the party will be held . (5) When the meeting will be held haven’t been known yet. 2：discussion Since you entered high school,you must have met with some problems in your study or life .One can talk about the problems . The others can give some advice. Try to use the following structures: The difficulty is...\what I find difficult is... The trouble is ...\what worries me is... My advice is...\what I would advise is... I think that...\what I think is... I want to tell you that...\what I want to say is.. 设计意图：设计该讨论以高中学生学习生活中遇到的问题为话题，贴近生活实际，激发了他们的兴趣。提供了几个的宾语从句、表语从句和主句从句的例子让学生们参考，一方面降低了难度，另一方面让他们能够学以致用，在平时的交流中能够用上名词性从句，真正达到其交际运用的功能。 【四】Summary & Homework 1. 自我评价 (1) 是否能正确无误地找出主语从句？能_____否___ (2) 是否能选出正确的引导词？ 能 _____ 否_____ (3) 是否掌握了主语从句的易错点？ 能 _____ 否_____ (4) 是否能用主语从句正确交流？能 _____ 否_____ 设计意图：设计通过课堂评价，让学生学会反思本节课所学内容和自己的学习行为和学习效果。 2. 作业 Option 1: 总结主语从句的知识点，制成思维导图。 Option 2: 根据以下表格内容，以How to learn English well?为题写一篇短文，可以自由发挥，在短文中尽可能运用主语从句。 5
How to learn English well? 为什么 要学好英语 英语是应用最广泛的语言，据报道，很多人都把英语作为第一或第二语言。
如何学好英语 不要放弃，虽然英语有时很难。 多练习，熟能生巧是有道理的。 最重要的是养成良好的学习习惯，比如利用字典、多和老师交流等。 设计意图：分层可选择的作业有效地兼顾了学生的个体差异，最后的作业设计既包括巩固所学内容的任务，同时也包括了扩展性任务，让学生进一步复习应用主语从句。 【五】教学反思 这是一节语法课，本人在教学设计中以学生为主体，运用“任务型”教学途径和本校的“三步激趣”教学模式，达到培养和强化学生语言实践能力和自主学习能力的目的。在经过本组老师的磨课指导下，积极吸取同组老师的建议，顺利完成了本节课，现将几点感想总结如下： 1.教学设计上，针对重点班的学生，容量充足，内容丰富，从什么是主语到什么是主语从句，再到准确地找出主语从句，最后总结归纳出本节课的重难点，如何选择正确的引导词，由易到难，层层深入，循序渐进，逐步提升学生的能力。 2.不同任务的处理上采用不同的教学方法。简单的学生能自主学会不讲，少讲。例如task1、2两个任务的处理上。重点的同学们出错的问题要重点点拨，加以方法引导。例如引导学生运用“FAT”法，提高了做题的正确率。 3. 整堂课师生，生生互动性强，每一个任务都是围绕学习者“学”的角度设计的。通过思考总结，培养了学生的自主学习、独立思考能力。通过通过小组活动，培养合作探究能力。设计的问题有的是开放式的，培养学生的创新能力和发散思维。
