In the past, knowledge was stored in books; nowadays, knowledge is stored in the Internet. Do advantages outweigh disadvantages?过去知识储藏在书籍里，现在知识保存在网络中。是利是弊？
Nowadays, people can have access to knowledge not only through books but also from the Internet. A number of people believe there are more benefits than drawbacks of reserving knowledge on the Internet and I could not agree more.
One of people's concerns is that there is amounts of information on the Internet and without the supervision of related departments, some people, especially the teenager may be misguided by misleading information. For example, there are so many kinds of novels on the Internet that it is difficult to distinguish which one is proper for a minor to read.
On the other hand, one obvious merit is that it has become more convenient for people to acquire knowledge. A range of ways can be employed to obtain knowledge, such as using an iPad, smart phone or a kindle. Apart from the various kinds of manners of reading, now people can gain knowledge wherever they want, which means instead of holding a book and reading quietly in a study, people can even read on a bus or subway only with their smart phones.
Another more meaningful advantage is that people in poverty can have easy access to knowledge if the knowledge is available on the Internet. As we know, compared with books, the e-books are more affordable and plenty of them are even free. Consequently, it allows more people to receive education contributing to social equality in some extent.
All in all, as I see it, the merits clearly outweigh the potential demerit because as long as there is supervision, the concern mentioned above will not be a problem anymore and I am convinced that sound supervision is on the way.
