The students can help each other and have a discussion after doing the following by themselves.一、How often do you have piano lessons? Twice a week._How often does he watch TV? He hardly ever watches TV._1. how often意为“_”，用来提问在某一特定的时间内进行某个动作的次数。答语为表示频度的副词，如：总是 _；通常 _；经常 _；有时 _；几乎不 _；从来不 _；或是表示次数的时间状语。如：每天 _；一周两次 _；一个月两次 _；一年三次 _。2. 虽然how long，how soon都表示“多久”的意思，但区别如下：how long 表示动作的持续长度，主要用来对一段时间（如in an hour，in two weeks等）提问。如：How long did he stay here? For about two weeks.how soon指再过多久，主要用来对表示将来的一段时间（如 in an hour，in two weeks等）提问。如：How soon will he be back? In two days.用how long，how soon，how often填空。 _ _ do you watch TV every day? For an hour. _ _ do you watch TV? I watch TV every day. _ _ will you finish your homework? In about half an hour.二、I go to the movies maybe once a month._maybe意为“_”，它与may be的区别如下：1. maybe是 _ 词，意思是“也许；可能”，在句中作状语，相当于perhaps，常位于句首。如：Maybe she is at home now, but Im not sure.2. may be中，may是 _ 动词，be是动词原形，两者构成完整的谓语形式，与主语形成系表结构，意为“也许是；可能是”。如：I cant find my watch. It may be lost.3. maybe 和may be可相互转换。如：你可能是对的。_ you are right. = You _ right.（设计意图：本节课的翻译探究先让学生自己做，然后在组内讨论。组内学生如果能把答案都讨论出来并展示，教师用语言给予鼓励表扬，若解决不出，看其他组能有解决的吗，最后老师再点拨。而且配有句子可以更好帮助学生理解知识点。）The end-of class test一、按要求改写下列句子。1.

Make a list of your weekend activities. The more the better. 2. Recite the conversation in 2d.3. Write a short passage about how often you do the things in 2b.本课亮点：1. 在导入时，引导学生列出一些常见的周末活动并让别的学生在黑板上进行板书，激活了学生的思维图式，而且也引出了谈论不同活动频率时所要使用的频度副词，紧扣本课话题。接着引导学生先单独说出课本插图中的活动，再集体说出插图中的活动，最后完成1a的活动列表。这种先说后写的过程可以给基础较差的学生创造更多模仿他人的机会。通过让学生看课本插图讨论问题的方式引入新课。这些问题的设计既巩固了有关外貌的单词，又引导学生描述别人的外貌特征，紧扣本课的话题。2. 在呈现目标语言时，根据现实生活中的真实情况与学生进行对话，从而
