文章概要

本文讲述了作者喜欢阅读书籍的爱好。从小时候开始，作者就在父母的引导下开始阅读，并对书中的故事产生了浓厚的兴趣。随着年龄的增长，作者发现阅读不仅能带来娱乐，还能学到很多知识。通过阅读，作者可以不出家门就游历世界各地，并且还能提高词汇量和写作技巧。最后，作者认为阅读书籍是一个每个人都应该培养的好习惯。

答案解析

错误1：But as I grow older, I realized that reading not only entertained me, but also helped me learn a lot of knowledge.
更正：But as I grew older, I realized that reading not only entertained me, but also helped me learn a lot of knowledge.
解析：此句中的“grow”是动词原形，但根据上下文和主句的时态（realized），应使用过去时“grew”。

错误2：Through reading, I could travel to different places in the world without leaving my home.
更正：Through reading, I can travel to different places in the world without leaving my home.
解析：整个文章都在描述作者现在对阅读的看法和体验，所以这里应该使用一般现在时“can”而不是过去时“could”。

错误3：Moreover, I also discovered that reading could improve my vocabulary and writing skills.
更正：Moreover, I discovered that reading could improve my vocabulary and writing skills.
解析：“also”在这里是多余的，因为“Moreover”已经表示了“此外”的意思，所以不需要再加“also”来强调。

错误4：Now, I spend much of my free time reading books.
更正：Now, I spend a lot of my free time reading books.
解析：“much”虽然可以修饰不可数名词，但在这里使用“a lot of”更为常见，表达更为地道。

错误5：I believe that reading books is a valuable habit that everyone should develop.
更正：I believe that reading books is a valuable habit that everyone should cultivate.
解析：虽然“develop”在这里不是完全错误的，但“cultivate”在表达“培养”某种习惯或技能时更为贴切。

错误6：I remember the first time I picked up a book and started to read it, I was fascinated by the stories.
更正：I remember the first time I picked up a book and started reading it, I was fascinated by the stories.
解析：在“started to read it”中，“to”是多余的，因为“start”后面可以直接跟动词的-ing形式。
