语法不能作为孩子英语学习的起点，更不能成为英语学习的重点和终点，学英语要从语法开始拓展。当孩子对英语有了一定的感性认识的时候再开始学习英语语法，这是最有效的。因为这个时候他可以利用英语语法进行拓展训练，利用语法拓展英语句型的篇幅，增加句子的难度，甚至递延到段落、篇章。
拓展训练是英语语法的衍生学习功能，即从简单句型到较复杂的句型以及从较短的句子到较长的句子的训练，甚至到达段落等更长的篇章内容。对于复杂的句型练习，一般可以要求孩子采用拓展式的操练方式。从简单的句子开始训练，在完成了简单句型的替换训练以后，接着增添新的句子成分或者分句，并用同样的方法，以分句或较复杂的短语为单位进行替换训练。
所有的句子成分都有拓展的空间，状语的拓展空间比较大，如时间状语、地点状语、方式状语、条件状语、让步状语、原因状语以及结果状语，等等。分句包括相当于句子成分的附属性从句和非从属的并列分句以及转折性分句，在练习中可以逐一增加分量，不断地拓展。
在进行这类拓展训练时，要尽可能地出现更多的句子成分，体现更加复杂的句子关系。在做这种训练时，要求孩子尽可能地用自己熟悉的背景知识，利用自己刚刚学过的或者正在准备的重点词汇或短语，这样不仅容易使孩子熟练地理解和熟悉各类句子的用法，而且还有助于轻松地掌握更多的词汇。
关于拓展训练的探作步骤，可以参考如下句例:
1.We speak good English because we study very hard,but I could not even open
my mouth last summer for I had never done any practice before that time.
这句话可以通过以下流程的拓展训练获得:
(1)We speak good English.
(2)We speak good English because we study very hard.
(3)We speak good English became we study very hard,but I could not even open
my mouth last summer.
(4)We speak good English because we study very hard,but I could not even open
my mouth last summer for I had never done any practice before that time.
拓展训练也可以由一个段落拓展到更多的段落，我们再参考如下句例：
2.We speak good English because we study very hard,but I could not even open
my mouth last summer for I had never done any practice before that time.
Oh,I should have been much better if I had been working hard since I came to
the school.
So I will practice more,and will have fulfilled all my task next Spring,when
I shall be having a business talk with an American company.
这一段话可以通过以下流程的拓展训练获得：
(1)We speak good English because we study very hard,but I could not even open
my mouth last summer for I had never done any practice before that time.
(2)We speak good English because we study very hard,but I could not even open
my mouth last summer for I had never done any practice before that time.
Oh,l should have been much better if I had been working hard since I came to
the school.
(3)We speak good English because we study very hard but I could not even open
my mouth last summer for I had never done any practice before that time.
Oh，I should have been much better if I had been working hard since I came to
the school.
So,I will practice more,and will have fulfilled all my task next Spring,when
I shall be having a business talk with an American company.
