There has been much debate about whether mobile phones and computers have a bad effect on the young's reading and writing skills. From where I stand, I firmly believe that it poses more negative effects.（6分钟）
Some people propose that using mobile phones and computers improve the reading and writing skills on the young. They have some good points to support their views. Firstly, with the help of the abundant software on these platforms, young people can do better in reading and writing. For example, the young may lose their interests on reading some foreign documentary or writing essay. However, by using the translation application and essay analyzer, young people can pick up their confidences of reading, and follow the advices given by analyzer to improve their essay.（19分钟） In addition, there are a lot of short but useful courses on the Internet, which allow the young to improve the skills of reading and writing. Thus, young people can manage their spare time to learn that through their mobile phones and computers.（24分钟）
However, I consider that these electric products would badly affect the young's reading and writing skills. The main reason is that young people may quickly get addicted to these products and rely on them. For example, the AI bot called chatgpt is very welcome and popular recently. However, some teachers have found that many students are rely on the chatgpt's answer once they meet the problems on homework. Thus, the young will loss their own thinking way if they use them too much. Besides, there are many short videos on the mobile phones application or computers website like Tiktok. However, if young people get addicted to it, they will lose the patiences of doing time-consuming things such as reading long documentary and writing essay.（36分钟）
In conclusion, although it seems that there are some positive aspects of using mobile phones and computers, their own thinking way and patiences will be changed if they use them too much. Thus, in a long term, I firmly believe that it is not good for the young to use such electric products.（38分钟）
