儿童是通过模仿成人的话语而学会语言的。遵循儿童语言发展的基本规律，教师可通过让学生模仿自己的语言表达，引导学生理解和掌握新授语法；通过创设语言情境，开展师生会话。例如：
T：I went to Mountain Tai last summer vacation. And I took some pictures there. Where did you go last summer vacation？And what did you do there？
S1：I went to Huaguo Mountain. And I saw a lot of monkeys there.
T：Huaguo Mountain is in Lianyungang. It’s very famous in China.
S2：I went to Suzhou Park and had lots of fun there.
T：You went to Suzhou Park and had lots of fun.Wonderful!
S3：I went to Jiuzhaigou last summer vacation. And I...
T：And you watched the sky there？
S3：Yes. It was so blue and so beautiful.
在此片断中，首先示范一般过去时的句子：I went to Mountain Tai last summer vacation. And I took some pictures there.然后向学生提出问题。尽管每一位学生的回答几乎是机械模仿了老师的示范句，但是之后学生的语言输出不仅模仿了结构，并且内容是反映学生真实生活的鲜活话语。模仿教学既避免了机械性句型操练的单调和乏味，又赋予话语以交际意义，有效地训练了一般过去时的用法。
因此，引导模仿是英语语法教学的起点。教师要引导学生在观察大量语言材料和进行充分语言实践的基础上，通过探究式的学习方式，自己去发现语言运用的规律，为在真实的交际情景中运用这些语法规则做好铺垫。
