优缺点对比的题目，在每年的考试中不算多见。通常而言，一年能考个五六次。其实，此类题目的写法比较简单，和同意与否的题目大同小异而已。

Internet technology is, to a great extent, updating all aspects of people’s life especially means of information storage. Hence, over the public there is the controversy whether storing knowledge by means based-on Internet is superior to traditional printed books.

首段仍然是由背景的介绍而引出本文需要讨论的主题。此段中，并未表达笔者的立场。

Primarily, the latest Internet technology makes it possible that a great deal of information can be stored by a tiny memory card. Instead, people had to build quite a few libraries and print millions of books in the past. The function of mass storage is what traditional books can never achieve. An instance in point is that people in recent years can put a small e-book reader in their pockets going everywhere they want, in which numerous books are available.

全文三个主段，其实都是典型的对比论证。主段一，究其一点，存储量的问题，将两者进行对比。从而论证海量存储是网络技术的一个优点。

Additionally, due to the advancement of related technology, currently knowledge can be preserved by multimedia means in forms of videos, audios, pictures and words. Admittedly, videos and audios can easily leave people more vivid impression, consequently enhancing people’s learning efficiency. By contrast, what paper books can store is only words and pictures, which are relatively monotonous and boring. This can perfectly explain why multimedia classrooms are rather prevalent in schools contemporarily.

相似于上一段，主段二重点讨论存储模式问题。网络存储形式多样，此为第二个优点。

Ultimately, people can readily access information saved online through some search engines. What people need to do is type some key words and wait for less than a second. Nevertheless, looking for a book in a large-scale library is not an easy job. Furthermore, sometimes if someone likes to borrow a book from a library located in other cities, he needs to make a couple of phone calls and wait for a few weeks.

本段是从查阅信息方便与否的角度来对比，进而得出网络技术的另一优点，高效搜索。因此，网络技术三战全胜，积九分，顺利晋级。

Briefly, dissemination of knowledge is an essential step of civilization, and undoubtedly Internet technology contributes substantially to it. Printed books are doomed to be replaced by high-tech products, written in history sooner or later.

结尾段，为了和全文不太重复，写的有些飘渺。首先肯定了网络技术存储知识加速了人类的文明化进程。其次预言，假以时日纸质书籍会被写入历史
