英语作文中家长意见的写作可以遵循以下几个要点：
开头问候
首先，可以简单问候老师，例如：“Dear Mr./Ms. [Teacher's Last Name],”
表达感谢
对老师对孩子的教导表示感谢，例如：“Thank you very much for your dedication and support in teaching [Child's Name].”
孩子表现概述
简要总结孩子在英语学科上的整体表现，例如：“Over the past semester, [Child's Name] has shown a good understanding of the English language and has made significant progress in reading, writing, listening, and speaking.”
具体表现
列举孩子在英语学习中的具体表现和进步，例如：“[Child's Name] has been actively participating in English class discussions and has shown improvement in grammar and vocabulary usage.”
存在问题及建议
如果孩子在某方面存在不足，可以委婉地提出，并提出改进建议，例如：“However, [Child's Name] sometimes struggles with [specific area, e.g., grammar] and could benefit from more practice and guidance.”
鼓励与期望
鼓励孩子继续努力，并对他们在未来取得更好的成绩表达期望，例如：“We encourage [Child's Name] to continue working hard and to believe in their abilities. We have every confidence that with your continued guidance, [Child's Name] will achieve even greater success in English.”
结束语
最后，再次感谢老师的辛勤工作，并表达对孩子未来的美好祝愿，例如：“Once again, thank you for your hard work and dedication. We look forward to seeing [Child's Name] grow and excel in English.”
签名
结束时，可以签上家长的名字，例如：“Sincerely, [Parent's Name]”
示例：
```
