教师的评语：结构合理，层次清晰。过渡词用得很好，使用了较复杂的句式为文章增色了许多。但画线地方有误，请改正。
(1)该教师对学生作文的错误地方画线有何作用?(8分)
(2)对该教师对学生作文的批改情况进行分析。(15分)
(3)假若此学生作文中出现的问题是学生群体中普遍常犯的错误，教师应该怎么做?(7分)

答案：

本题解析：

(1)教师对学生的错误地方画线。是一种让学生修改其错误的提示性标记。材料中教师在错误处画线，有助于学生在自我更正的过程中积极地思考出错的原因.从错误中吸取教训。同时，学生能够对所学知识进行查漏补缺.可以认识到自己还没有完全掌握哪些知识点或哪些语言规则掌握得不准确。学生可以从错误中学到知识.知识的残缺也会得到及时的弥补。

(2)该教师在批改此学生的作文中，能够认真阅读并指出错误之处，并希望学生自行改正，是教师批改的一大优点.但该教师没有区分错误的类型，对于出现的错误不加区分一律画线，是其批改中出现的不当之处。有的学生可以悟出来，如be afraid make mistakes，play a important等。此类错误不必多加解释，经过提示，学生可以自行解决。但对于As a matter of fact为什么画线.学生很难发现其出错原因是前面用了in fact，造成重复现象。还有to be patient when vou still do poorly in Chinese学生很可能搞不懂错在哪里。这时，教师应给出详细解释，确保学生理解错误原因。因此.对学生书面表达中出现的错误的处理方式应有别于口语中出现的错误处理方式。从某种程度上说.书面表达错误的处理应更加严谨.要求学生充分运用所掌握的语言知识来监察和修改语言输出.少出或不出语言形式方面的错误。

(3)教师如果在教学过程中发现学生普遍存在某一类的言语错误，此类现象可以看作对课堂教学是否正确高效的一种反馈。教师可以通过对普遍性错误的分析.找出教学中的薄弱环节，从而针对学生的实际情况，及时优化教学内容.改进教学方法.促进教学质量的进一步提高。
