Unit 4 Astronomy: the science of the stars话题：职业选择【场景背诵】－－体会黑体表达并背诵全文When I graduated from high school, I wanted to major in comparative literature. But, once I found out my friends were going into “real” majors, like marketing, nursing, and engineering, I figured I needed to do the same to ensure a good career. So I changed my mind and chose Business Management as my major. I forced myself to believe that I would enjoy it and succeed in the future, but eventually I exhausted myself understanding the economy and trying new marketing techniques. Coming out of this experience, I realize it is OK to be different from others and to study things like classics, art history and other majors offered in the College of Humanities (人文学科)! (2019·高考天津3月卷· D)【话题运用】－－根据提示进行写作1．拥有更广阔的视角，我们将会更加自由，更加思想开明，并且有更少的桎梏限制我们的发展。

新人教最新春高中Unit4不定式短语作目的状语学案必修第三册英语

一、不定式(短语)作目的状语不定式(短语)作目的状语，主要用来修饰动词，表示某一动作或状态的目的。

1．to do...为了……这种形式可置于句首(起强调作用，有逗号与句子隔开)或句尾(通常不用逗号隔开)。

在句首时常译为“为了……”；在句尾时常译作“以便……，目的是……”。

To catch the early bus，I got up early this morning.为了赶上早班车，我今天早上很早就起床了。

We work hard to be admitted to a key university.我们努力学习，目的是考上重点大学。

[名师提醒]　不定式(短语)表示的是主语的目的，因此其逻辑主语通常是句子的主语。

[译]为了画好地图，你需要一支特殊的钢笔。

[误]To draw maps properly，a special pen is needed.[正]To draw maps properly，you need a special pen.2．in order to do...为了……这种形式更能突出目的性，既可以置于句首又可以置于句尾。

In order to lose weight，he takes exercise like crazy.＝He takes exercise like crazy in order to lose weight.为了减肥，他拼命锻炼。

高中英语_ 必修三第四单元语法教学设计学情分析教材分析课后反思

主语从句新授课课题名称主语从句新授课Subject Clause一、教材依据：普通高中课程标准试验教科书英语3（必修）人民教育出版社。

二、设计思路指导思想:通过填表和写作活动，培养学生自主学习和探究的学习技巧；使知识与技能得以提高。

设计理念:通过小组合作，探究互动，质疑解惑，培养学生问题、解决问题的能力以及团队合作精神。

教材分析：名词性从句之主语从句对高中英语是一个十分重要的，它在高考的比例中也是举足轻重的，无论单选完形还是阅读，改错，无所不在。

尤其是作文中，如果能漂亮地使用几个名词性从句，就能为你的文章大添光彩。

因此，我们要对它着重讲解。

学情分析：这是一个普通班，学生基础不很好，词汇量不足，但是有很多同学学习认真，求知欲强。

三、教学目标知识与能力：让学生在学会主语从句的基础上，提高学生的听说读写用等技能。

方法与途径：运用观察法和填表法等任务型教学法和综合运用型教学法，让学生自主观察归纳总结该语法的节本结构和基本规则，最后通过写作来记忆语法的基本形式完成这节教学。

情感与评价：让学生在轻松愉悦的气氛中学会主语从句，同时培养学生小组合作和竞争等意识。

现代教学手段的运用：使用多媒体辅助教学，呈现一些幽默搞笑的图画四、教学重点掌握主语从句的引导词的分析和确定，及主语从句的使用五、教学难点如何选用正确的引导词六、教学准备针对上述情况，我决定重新整合教材内容，进行优化教学设计和课件的制作，并提前进行分组分工等活动以便高效地进行课堂教学。

七、教学过程Step 1. Lead -inActivity 1: Sentence MakingChoose one group through the Fortune to make a complete sentence.【设计意图】开课伊始，用幸运转盘选出一组同学，分别拿着一个带有单词的卡片，迅速排列组成正确的句子，引出本节课的主题—主语从句。

Step 2:Reading and discoveringLet students read the following sentences and try to discover the subject of each sentence.Then ask some students to read them and tell others the subjects.1.Wang Peng sat in his empty restaurant feeling very frustrated.2.They began to talk about menus and balanced diets.3.To see is to believe.4.Having you sit here is a great honour.5.What is even more important is that as the earth cooled down, water began to appear on its surface.6.What many scientists believe is that the continued presence of water allowed the earth to dissolve harmful gases and acids into the oceans and seas.【设计意图】让学生从观察例句找出主语入手，旨在让学生从充当词方面，明白了主语不仅仅可以由名词/代词/动名词/不定式还可以由句子充当。
