Thanks for listening!教材分析
本单元围绕话题“发明”，介绍了我们日常生活中一些常见物品的发明历史，如：电视、电话、拉链、茶叶、薯片和篮球等，它们被发明的时间、被什么人发明及其作用或发展等内容；从语言结构上，需要学习被动语态的过去时。本单元是九年级《go for it》第六单元“When was it invented?”。本单元涉及内容是本书当中比较重要的一部分。被动语态结构及运用是教学中一个难点和重点，也是学生比较不容易理解的部分，因为它是建立在各种时态之上的。 另外通过对我们熟悉经常使用的发明物的历史来开阔眼界，丰富学生的阅历，使学生养成勤于思考，善于总结的好习惯。本节课的内容是Grammar Focus-4c。
一、 教学目标：
1.知识和技能目标：
1) 学习掌握下列词汇：fridge, low, somebody, translate, lock, earthquake, sudden, all
of a sudden, biscuit, cookie, musical, instrument
2）进行一步复习巩固学习Section A 部分所学的生词和词组。
3）进一步学习运用一般过去时态的被动语态。
4) 掌握主动语态变被动语态的方法，并通过不同方式的练习，来熟练运用。
2.过程与方法目标：
1）能运用所学知识练习被动语态的句式。
2）能用所学句型进行交际练习。
3. 情感态度价值观目标：
1) 培养想象力，善于观察事物。面对难题，用积极的态度去解决，发挥想象力，认识世界，改造世界。
2) 使学生懂得人类的科学发明创造了丰富的物质文明。培养学生的创造发明的能力和愿望
二、教学重难点
1. 教学重点：
1) 学习生词fridge, low, somebody, translate, lock, earthquake, sudden, all of a sudden, biscuit, cookie, instrument21世纪教育网版权所有
2) 掌握一般过去时的被动语态
2. 教学难点：
1) 一般过去时态的句子变为被动语态。
2) 综合运用所学的知识进行练习运用。
课后反思
本课是一节语法课，讲这种课具有很大的挑战性。因为新课标要求淡化语法讲解，这种类型的课到底怎样去上，我心里也没底，而且又是讲被动语态，所以感觉难度挺大。
本课是SectionA 部分的语法，也是本单元的语法，所以一上来应该先复习前面学过的句型课文等，以旧引新，循序渐进进入本课的语法教学。21世纪教育网版权所有
在Grammar Focus 环节，我让学生大声朗读重点句型，让后小组讨论句子结构，归纳总结一般过去时态的结构及用法，学生基本能总结出来。之后我又通过贝尔发明电话这一例子，跟学生探讨了如何变主动语态为被动语态，涉及到主语谓语宾语，基本用英文来解释，学生不一定听明白，由于口语水平有限，我的讲解可能比较繁琐。还有这种语法课应该怎样讲，我也很困惑，不知我这种讲法合不合适。21教育网

三、教学过程
Ⅰ. Revision
1. Review the structures we learned in SectionA. Ask students to make conversations according to the structures:【来源：21cnj*y.co*m】
When was … invented ?
It was invented in…
Who was it invented by?
It was invented by…
What is it used for ?
It is used for…
2. Let some Ss tell something about how tea was invented by accident.
Tell something about how tea was invented by accident.【出处：21教育名师】
One day Shen Nong was boiling drinking water over an open fire. Some leaves from a tea plant fell into the water and remained there for some time. 【版权所有：21教育】
It produced a nice smell so he tasted the brown water. It was quite delicious and one of the world’s favorite drink was invented.21*cnjy*com
Tell something about Lu Yu and his Cha Jing.
Lu Yu “the saint of tea” mentioned Shen Nong in his book Cha Jing. The book describes how tea plants were grown and used to make tea. It also discusses where the finest tea leaves were produced and what kinds of water were used.
It is believed that tea was brought to Korea and Japan during 6th and 7th centuries. In England, tea didn’t appear until around 1660. The tea trade from China to Western countries took place in the 19th century.
Ⅱ. Grammar Focus.
学生大声朗读Grammar Focus中的句子，然后小组讨论发现什么规律。
让学生总结句子结构及规律。
Ⅲ. Grammar
1.一般过去时态的被动语态的用法和构成
英语有两种语态：主动语态和被动语态。主动语态表示主语是动作的执行者，而被动语态则表示主语是动作的承受者。www-2-1-cnjy-com
一般过去时被动语态的结构为“主语+ was /were +及物动词的过去分词 (+by+动作的执行者).”。 21教育名师原创作品
主动语态如何变被动语态：教师举例：
Active Voice：Alexandar Graham Bell invented the telephone in 1876.
Passive Voice: The telephone was invented (by Alexander Graham Bell) in 1876.
Ⅳ. New words
图片呈现一些新单词：translate, lock, earthquake, sudden, all
of a sudden, biscuit, cookie, musical, instrument
Ⅴ. Practice
Work on 4a:
1. Tell Ss to read the sentences in 4a and rewrite the sentences using the passive voice.
2. 做题方法点拨示例：
① 点拨：原句为一般过去时态，原句的谓语动词为sold，宾语为the fridge；改为被动语态时，应将the fridge作主语，谓语动词用was sold的形式。
They sold the fridge at a low price. →
The fridge was sold at a low price.
② 点拨：分析原句的句子结构可知，stole是谓语动词，my camera是句子的宾语；改为被动语态句时，应将my camera作句子主语，谓语动词用was stolen的形式。
Somebody stole my camera from my hotel room. →
My camera was stolen from my hotel room.
学生们自主将其他三个句子变成被动语态。
3. 让学生上黑板做其余三道题，其余同学在下边自己做。最后，教师与同学们一起校对答案，并对学生们有疑问的地方进行解释，或做出合理的分析点拨。
Where were these photos taken?
We were advised not to go out alone.
The book was translated into different languages by different writers.
Work on 4b: Complete the sentences with correct forms of the verbs in the box.
1. 让学生们阅读方框中的词汇，了解词汇及句子的意思，为进行填词做好准备。
eat, like, invite, tell, lock, ring, break, bring
2. 认真阅读每个句子，根据上下文确定空格处应填的意思。
3. 逐句进行分析推敲，然后分析句子的时态及语态，用适当的形式填空。
1) You ____________ to the party last night, weren’t you? Why didn’t you go?
2) The earthquake happened all of a sudden, but luckily the villagers _____________ to a safe place. 21·世纪*教育网
3) The door ___________ when we arrived, so we ______ the bell. 21*cnjy*com
4) The students ___________ not to eat or drink in class, but Ruby ______ the rule when she started eating a biscuit in science class.
5) The cookies __________ by the hungry kids in less than 20 minutes, and they really _____ them.
4. 最后，通读一遍所有句子，进行综合理解，看句子的意思是否通顺，合理。
5. Check the answers with the Ss.
1. were invited 2. were brought
3. was locked, rang (前一句中，门是被锁的，故应用被动语态；后一句中，我们去按门铃，是主动语态。)
4. were told, broke (前一句中，学生们是被告诉不要做这些事情，故应用被动语态；后一句中，Ruby违反规则，则是主动语态。)
5. were eaten, liked (前一句中，饼干是被孩子们吃掉了，故应用被动语态；后一句中，孩子们喜欢这些饼干，则是主动语态。)
Work on 4c: Decide whether active or passive forms should be used in these sentences. Write the correct forms in the blanks.
