Warming up and leading in热身导入
Look at some pictures about weekends, let students discuss what they usually do on weekends. Try to learn the conversation, and then let Ss ask and answer in pairs.
T： What do you do on weekends? S1: What do you do on Sundays?
Ss: I always watch TV。

S2： I usually go shopping 。

S1： What does she do on weekends? S1: What do they do on weekends?
S2： She often reads books. S2： They sometimes go swimming。

T： Do you go to the movies? S1： Do you often play basketball?
Ss: No, I never go to the movies。

S2: Yes， I do。

（设计意图：利用图片引入,运用画面激发学生的学习兴趣,让学生感知一般现在时。

利用精美的图片,让学生两两一组进行会话,加深对频率副词的理解与运用。

）
Practice
Let Ss translate the phrases or the sentences into English。

1。

你在周末通常做什么？ ________________________
2.我总是锻炼。

____________________________
3.她在周末通常做什么? __________________________
4。

她经常帮助做家务。

___________________
5. 你多久看一次电影？ ______________________________
6。

我去看电影一个月一次。

___________________。

7。

他多久看一次电视？ ________________________？
8. 他几乎不看电视. __________________________ 。

(设计意图:一般现在时中的频率副词的用法是学生的易混点，这种训练可以帮助学生习惯英语句式的表达,助动词do和does虽然初一已经很熟悉，但是学生还是会出现使用混淆的现象，并且还要注意第三人称单数实义动词的变化.）

Pair work:
Let Ss work in groups to make sentences using the pictures, then try to conclude the rules of frequency adverbs 。

I always get up late.I get up late every day.
How often do you ...?
......
I ...
Once a month Twice a week Three times a week
Four times a week Once or twice a week Uncle Wang Linda Bob Lucy Mr White
-How often does he/she ...?-He/She ....
（设计意图:通过学生看图对话，以小组的方式探讨频度副词的构成特点,为下一步总结巩固语言结构,做好铺垫.)
Help Ss to conclude frequency adverbs 。

Grammar Focus
一． 观察:
1. What do you usually do on weekends ？ I always exercise 。

2。

What do they do on weekends ？ They often help with housework 。

3。

What does she do on weekends? She sometimes goes shopping 。

4。

How often do you go to the movies?
I go to the movies maybe once a month。

5。

How often does he watch TV？ He hardly ever watches TV。

6。

Do you go shopping？ No， I never go shopping.
结论：(一）以上几组例句均为_________时态，how often 意为“__________",是用于提问在某一特定的时间内进行某个动作的次数。

1.答语应为表示________ 的副词或副词词组。

总是______ ; 通常______; 经常_______；有时________；
几乎不____________；从来不__________.
2。

或者是表示次数的时间状语。

如：
每天_________；一周一次_______________;
一个月两次_______________；一年三次_______________。

句型:How often + do/does sb。

do sth。

?
答语： always / usually / often / sometimes / hardly ever / never once /twice/three times┄基数词+times/ + 单位时间
结论(二）：实意动词的一般现在时变一般疑问句时应在句首加_______ 或___________。

该加哪一个应看主语，当主语是 ____________人称、____________人称、______________复数及_____________ 名词时加do;当主语是____________ 人称单数及__________ 名词时加_____________。

（设计意图: 通过系统训练与板书设计的指引与归纳,学生自然而然就能总结出how often的用法；实意动词的一般现在时是学生已经学过的内容，通过给出学生例子，引导他们自己发现归纳总结语法规律，在加深学生认识的同时，还训练了他们归纳与总结的能力)

Homework
1. （You Must）
Copy and remember the sentences in the Grammar Focus.
2。

(If You Can) Writing
Write an article to introduce(介绍) your and your best friend’s free time activity frequencies。

要求：（1) 运用一般现在时和频度副词
（2) 语句通顺，格式正确
（3) 字数不少于60
本节课亮点:
1。

利用生活的图片领着学生走进课堂,运用学生日常活动的照片激发学生的学习兴趣，让学生感知句型。

让学生两两一组进行会话，加深对频度副词的理解与运用。

学生踊跃发言，课堂气氛活跃。

激发了学生的学习积极性，让学生在轻松好奇的氛围中自然引入本节课的目标语言.
2。

通过学生看图对话,让学生体会目标句型的构成特点，为下一步的总结巩固语言结构，做好铺垫.语法讲解层层递进，引导学生对句型的特点和句式进行分析，并进行及时的训练，起到事半功倍的作用。

在对语法知识的练习中，本着高效训练的原则，题目的设计具有典型性、适量性和层次性，从控制性操练、半控制性操练到开放性语言知识应用，层层深入，即夯实了基础，又提高了学生的技能。

另外,练习的设计充分考虑到不同层次的学生，例如在group—work 这一阶段,让能力差的学生用how often句型进行调查，让中等生收集调查结果，让优秀生负责写报告，这样使每一个层次的学生都能参与到课堂中来,使每一位学生都能体会的成功的喜悦.
3.分层布置作业,可以让学生根据自己的实际情况来进行选择，这样既能让大多数学生有一
种成就感，又能让优秀生的能力得到进一步的提升。

不足之处：
1。

本堂课容量很大.学生最后的报告完成不充分,不是每一个小组都能完成任务.
2.要留给学生充分的时间去操练，才能更好的在语境中对所学语言加以运用。
