Presentation： （1）4a功能识别：学生阅读句子，识别红色连词含义，辨析蓝色形容词用法；教师核对并强调用法区别。 Do you ever bow? No, that’s so formal that we don’t do it these days. Should I bring something? Sure. Bring a small gift, but don’t bring food unless the host asks you to. I was surprised by your bow. We usually just say “hello” or shake hands in the US. That’s surprising! In Japan, we bow as soon as we meet a teacher. Don’t look so embarrassed! But it is embarrassing! （2）形容词-ing与-ed辨析 ①形容词后缀-ing意为“令人……的”，通常用来描述事物的属性或特性。 ②形容词后缀-ed意为“（人）感到……的”，一般用来描述人的感受或情绪。 I am interested in different customs around the world. 我对世界各地不同的风俗感兴趣。 The culture of different countries is very interesting. 不同国家的文化十分有趣。 注意：修饰人的 表情、眼神、微笑、声音、脸色（look, expression, smile, voice）时，全部用-ed形容词。 a surprised smile 惊讶的微笑 an embarrassed look 尴尬的神情 （3）so... that引导结果状语从句 ①结构 so+形容词/副词+that从句 so+many/few+可数名词复数+that从句 so+much/little+不可数名词+that从句 so+形容词+a/an+可数名词单数+that从句 He ran so fast that I couldn’t catch up with him. 他跑得如此快，以至于我追不上他。 There are so many students in the hall that we can’t find a seat. 大厅里有如此多的学生，以至于我们找不到座位。 We have so little time that we can’t finish the work today. 我们的时间如此少，以至于今天完不成工作。 It is so important a problem that we must discuss it. 这是一个如此重要的问题，以至于我们必须讨论它。 ②so... that 句型的否定形式可用too... to...或not... enough to构成的简单句代替。 The girl is so young that she can’t look after herself. → The girl is too young to look after herself. → The girl isn’t old enough to look after herself. 这个女孩太小，以至于不能照顾自己。 （4）unless引导的条件状语从句 unless意为“如果不，除非”，相当于if... not...。unless引导条件状语从句，如果主句为一般将来时、祈使句或谓语中含有情态动词，从句通常用一般现在时，即“主将从现”。 You should be polite unless you are in your own home. 除非在你自己家里，否则你都应该有礼貌。 Wait for the host unless he asks you to eat first. 等主人先开动，除非他让你先吃。 You will fail the exam unless you study hard. = You will fail the exam if you don’t study hard. 如果你不努力学习，就会考试不及格。 （5）as soon as引导的时间状语从句 as soon as意为“一……就……”，引导时间状语从句，用于表示某个动作紧接着另一个动作发生。as soon as引导的时间状语从句可置于主句前或主句后，位于主句前时应加逗号。若主句为一般将来时，从句常用一般现在时表示将来。 You should take off your shoes as soon as you enter a Japanese friend’s home. 你一进入日本朋友的家里，就应该脱鞋。 As soon as we get to a foreign country, we should learn its local customs. 我们一到一个外国，就应该了解当地的风俗。 I will say thanks to the host as soon as I finish the meal.我一吃完饭，就会向主人道谢。 2.

(unless) In Türkiye, people don’t kiss one another on the cheek unless they are good friends. Japan: Take off your shoes. You do this when you enter someone’s home.

As soon as she arrived, she ran to the beach with her watercolors, brushes and paper. The city of Zibo is so popular that many people want to go there for a trip this year. Unless the Monkey King can hide his tail, he cannot turn himself into a man. As soon as she heard the news, she decided to spend the rest of her life doing what she loved most — watching birds. （4）4c练习：用所给词完成 culture shock 短文，综合运用语法与词汇；学生完成后，教师核对答案并引导判断：The writer is from Germany. surprising surprised interesting interested so ... that as soon as unless Do you know what culture shock is? You may feel it when you experience a new culture, because the new culture is so different from your own that you feel surprised. For example, I experienced this as soon as I got off the plane in Peru last year. People were standing on my right and left, even though there was plenty of space on the bus! That was really surprising to me. In Germany, people usually like more personal space, and we don’t stand close to someone unless we know them very well. But once I was used to it, I became more curious and interested in learning about the culture there. It’s so interesting to discover cultural differences like this! 3. Production：话题输出（4d） （1）语篇结构：按照“介绍—初印象—差异—转变—现在感受”的五段式框架，组织一段连贯的口语表达。 Introduction—First impression—Differences—Changes—Feelings now （2）小组练习：学生两人一组，根据表达支架，必须用到至少2个连词与形容词，完成“文化冲击经历”的故事，教师巡视指导，纠正语法与表达错误。 My Culture Shock Story Do you know what culture shock is?

Adjectives -ed：sb. feel…（人感到） surprised /embarrassed/interested -ing：sth. is…（令人……） surprising /embarrassing/interesting 2. Conjunctions so...that：如此……以至于……（结果） unless：除非 = if...not（条件，主将从现） as soon as：一……就……（时间，主将从现） 八、教学反思 1.本节课通过情境导入、语法精讲、分层练习与口语输出，有效落实教学目标，学生能基本掌握三大连词与-ed/-ing形容词用法，但主将从现仍有部分学生掌握不牢，需加强专项训练。 2.-ed/-ing形容词在修饰表情、微笑、声音时易混淆，需增加更多对比例题巩固。 3.语篇填空综合运用性强，部分学生语境判断较慢，可提前给出关键词提示降低难度。 4.口语输出环节学生参与度高，但文化素材储备不足，可提供更多国家礼仪支架，提升表达丰富度。可进一步强化中外文化对比，让语法学习更贴近真实交际，更好落实文化意识目标。 学科网（北京）股份有限公司 $
