Unit 4 Don’t eat in class
Section B 2b-3c
一、教材分析:
教学内容为人教版目标英语七年级下册第四单元Section B的第二课时。第四单元话题是规则(rules),教材中出现的学校家庭的规则贴近学生的生活,容易激发学生的学习共鸣与兴趣,帮助学生客观看待规章制度。 本节课是读写课,通过对2d书信的阅读,在继续学习掌握新的词汇及表达方式的同时,对前面几节课所学语言知识点在实际运用中巩固,并运用所学语言知识进行写作训练。 二、学情分析:
七年级学生对情态动词can以及其否定形式can't 的使用已经很熟悉,经过前面几节课的学习对have to和祈使句结构也有了解,能够用英语表达简单的规则。
本节课是要求学生运用所学语言知识来谈论规则,进行实际综合训练并上升到笔头训练,写一封信来谈论一下自己应遵守的一些规则和自己的看法,对学生来说有一定难度。 三、教学目标: 1. 语言知识目标:
1) Words & expressions: dirty, kitchen, more, noisy, relax, read, terrible, feel, strict, be strict with, remember, follow, follow the rules, luck, keep, keep …short,learn,
2) Talk about rules by using Imperatives Don’t …, can’t, have to, must: ① Don't leave the dirty dishes in the kitchen. ② I can't relax either.
③ I must read a book before I can watch TV. ④ I have to go to bed before 10:00.. 2. 情感态度价值观目标:
能读懂一些英语的规则制度,能用英语表达一些简单的规则,理解没有规矩不成方圆;无论是在学校时还是在家庭中以及以后走上社会都应当遵守规则,按规则办事。 四、教学重难点
1. 教学重点:1) 学习本课出现的新词汇及表达方式,通过阅读练习进一步学习运用新语言知识。
2) 能用所学的语言知识来写出自己在家中和在学校中的一些规则。
2. 教学难点: 1)理解must, have to/ can/can't的用法
2)写一封信来谈论一下自己应遵守的一些规则,并表达自己对这些规则的看法。 五、教学过程
ⅠWarming- up and revision
Read the new words and expressions in the unit, then do some exercises. ⅡPresentation 1 Reading
1) 2b Fast reading
T: There are many rules in Molly's home and school. She feels unhappy. Read the letter and find the answer to this question: What does Molly feel about the rules? (she feels terrible.) 2) Careful reading: 1) Read the letter again and underline the rules for Molly.
2. Work on 2c. Read the letter again and complete the sentences with have to/ must, can or can't. 阅读指导:
1) 首先,认真阅读2c中的这些句子,明白它们所谈论的相关规则。
2)带着相关规则再去读2a中的信,在与之相关的内容处认真分析,理解规则的真正含义,并填上正确的词汇。
3)再次阅读这些句子一遍,看是否通顺。 4) Check the answers.
5) 求助信的特征和语言。 1)) 书信称呼都是用Dear…
2)) 称呼后用逗号,不用冒号,这是中英文信件区别之处。
3)) 求助信中第一句是核心句,例如There are too many rules! 主题句后就是解释说明主题句的细节句。 4)) 信件结束前一般会有明确求助的句子,即What can I do? Language points
have to & must: have to 意为“不得不”,表示客观上的必要性,有人称和数的变化,其后要跟动词原形,其否定式don’t / doesn’t have to 表示“不必”。must 意为“必须”,强调说话人的主观看法,没有人称和数的变化,其后要跟动词原形,其否定式mustn’t 表示“不准;禁止”。含有have to和must的句式如下:

2.写作指导: 首先,可以再次阅读2b及3a中的短信的内容及格式。其次,模仿这两封信的格式写好自己信件的格式;然后,根据刚才自己小组讨论的规则整理成一封文字通顺的信件。并且,表达自己对这些规则的想法或看法。之后,以礼貌的话语请求Dr. Know的帮助。最后,再通读一遍自己的短信看语句是否通顺。 3. Ss write the letter on the workbook.

教学反思:
经过前面几节课的铺垫,学生对于情态动词can、can't、must、have to及祈使句结构都有了解,也能用英语表达简单的规则。本节课要求学生运用前面所学语言点进行笔头训练,写一封信来谈论一下自己应遵守的规则及对这些规则的看法,虽有一定难度,但由于写作前对所学的词汇及句子结构进行了大量的训练,以及对学生进行了阅读和写作前的指导,学生基本上能写好这封信。有小部分学生在情态动词与祈使句的转换表达上还有些难度,有小部分学生的书面表达能力还较差,今后还得多加强这方面的笔头练习。
