中国英语学习者学英语语法学得辣么辛苦，那么歪果仁要不要学语法呢？

答案是：要。

先来看一个电视剧片段(此剧在之前介绍了)

里面有这样一段对话：

Sister: Can you help me?
妹：你能帮帮我吗

Brother: With what?
哥：帮什么

Sister: I don't understand my homework.
妹：我作业不会写

Brother: You're asking me?
哥：你问我干嘛
Brother: I don't understand my own homework.
哥：我连自己的作业都搞不懂了

Sister: I know, but you're all I got.
妹：我知道啊 但我没别人能问了

Brother: What kind of homework is it?
哥：这是什么作业

Sister: Grammar.
妹：语法

Brother: I ain't great with grammar.
哥：我的语法也不好

剧中女孩年龄为9岁左右，说明native English speaker从小学开始学语法。

我们看下他们的书是咋样的：

书中是这么写的：

There's a list of sentences, and you're supposed to say if each one's a complete sentence or not.
The first one is, "Most people in the country"
下列的句子中 你得判断出 哪句是完整的句子
第一句是"我国大多数人"

两个学渣边看书边探讨：

A complete sentence always contains a verb.
一个完整的句子必须要有动词。

没错。这在英语句法中非常基础又非常重要的一条，关系到你对句子的分析与理解。

A verb is a word that describes an action.
动词用来描述动作。
I play checkers. You eat spaghetti.
比如：我玩西洋跳棋 你吃意大利面

哇~人家的教科书很生动嘛！

两个学渣经过一番研究，最终得出“Most people in the country”不是个完整的句子，因为缺少动词。

所以，我们的结论是：『以英语为母语的歪果仁』需要学习英语语法，而且可能有专门的语法课本。

然而，这个结论可能过于绝对，因为根据外国网友的自述，不是每个学校都会教授语法，以英语为母语的人也不一定都有“语法”的概念。

网友Timothy Sargent说：

Do they learn it naturally? Yes, any native speaker will learn grammar naturally just by absorbing it from other speakers, texts, etc., including native English speakers.
会不会自然而然地学到语法？当然，每个native speaker都会在日常交际中吸收到语法知识。

然而，

In terms of formal education on English grammar, it really depends. I attended a private school where grammar was taught as a subject. We learned new rules regularly and practiced them daily. However, when I reached high school, I learned that other students who had grown up in the public school system in the same town had never studied grammar at all, so their writing skills were sometimes lacking.
但是，在学校会不会学就不一定了。我以前的学校是把语法当作一个学科，但我读中学的时候发现有些同学以前没学语法，他们的写作技能就会差一点。

所以，『以英语为母语的歪果仁』不会像外语学习者一样学大量的条条框框的『语法规则』，然而还是要学的，而且学习语法对于『写作技能』有很大影响，特别是学术型、专业型写作。
