这篇作文的主题是电子书与纸质书的比较，作者表达了对电子书的偏爱。但在内容表达、篇章结构和语言运用上还有一些可以改进的地方。根据评分标准，这篇作文可以被评为第三档：13-18分。

**优点：**
1. 作文清晰表达了作者喜欢电子书的观点，并给出了三个理由。
2. 文章结构基本完整，有开头、中间段落和结尾。

**不足之处及建议：**

1. **标题大小写问题**：
   - “E-books or paper books” 两个单词应该首字母大写：“E-Books or Paper Books”。

2. **第一段**：
   - “It is well know that books are very important in our in lives.” 这里有拼写错误，“know”应为“known”，“in”重复并不必要。
   - 开篇的语句有些笼统，可以更加具体地引出电子书和纸质书的对比主题。

3. **第二段**：
   - “e-books can let me know world and improve more knowledge.” 改为“e-books allow me to learn about the world and acquire more knowledge.”
   - “e-books are very convenient to carry with.” 改为“e-books are very convenient to carry.”

4. **第三段**：
   - “as far as I am concerned,My favorite is e-books.”，“My”不应大写，且表述可以更自然地结束全文，例如：“Therefore, my preference is clearly for e-books.”

5. **整体语法和用词**：
   - 语言相对简单，可以尝试使用更多样化的语法结构和词汇，以提高表达的丰富性和准确性。

综上所述，这篇作文具备了基本的结构和观点，但在语言精确性和多样性上需要加强。建议进行详细的语法和用词检查，以及简化某些表达以避免啰嗦。
