语言操练的过程既可以增强语感，又可以培养自信心。
教师可以根据班级情况，分配朗读的方式和时间。
教师在采用PK的方式进行朗读训练时，要注意每组PK完后，有适当的点评，让后面的小组有一定的提高；如果让学生点评的话，注意引导学生从流畅度、参与度和准确度等方面进行评价。
学生能够正确提出问题，也是能力的体现，教师需要引导学生，一步一步朝着正确答案去思考，可以运用课文中的文本语言，也可以拓展例句提供新的语境，还可以根据已学知识理解新知识。

语法是语言组织的规律，没有语法，语言便只是一些杂乱无章的符号，就会失去英语的工具性。
教师在教授语法时，要注意方法和策略。
本课要突破不定代词和不定副词的用法。
先通过听读对话，理解各个不定代词的含义，然后通过语篇填空，让学生尝试使用这些不定代词，然后自己归纳总结他们具体的用法，最后在第四步中检测学习的程度。
在语法习得过程中，教师要注意自己的角色，注意引导学生学会观察、思考、讨论、归纳。
