The lecturer discusses the drawbacks of making use of digital libraries rather than of using traditional libraries. This casts doubt on the reading passage’s claim that digital libraries are easy to access, convenient to use, and vigorous way (병렬구조상 형용사를 사용하는 것이 맞는 것 같아요) to share ideas.
To begin with, not everyone can does not afford to buy computer to access internet on-line. The poor will be discouraged with by not having opportunity to have an access to variety of approach to information. So (so로 문장을 시작하는 것은 좋지 않습니다. 가능한 피해주세요.), only few narrow groups people can have the possibility of getting information, for that reason this gap generates the polarization of the knowledge. Thus, the lecturer argues against the point made in the reading that anyone can access easily regardless of mobility problem. (thus를 쓰셨기 때문에, lecturer이 어떤식으로 argue를 하는지 간단하게 써 주는 게 더 좋을 것 같아요)
On top of that, taking advantage of digital libraries is not a convenient activity. You cannot stop searching the materials what that you want, and this time-consuming behavior is not efficient way to study. (이 앞의 내용이 lecture에서 나왔다는 말이 없어요. 물론 뒤의 내용을 토대로 추측이 가능한 부분이지만, lecture의 의견이라는 것을 써 주시는 것이 좋을 것 같아요.) This rebuts the reading passage’s assertion that accessible opportunity of doing researching at home is fairly(=pretty, reasonably) time-saving and convenient.
Finally, authors of books in digital library’s books would be discouraged. People don’t have a willingness to buy a book with their own money. This is attributed to the reason that everyone can borrow and read a book by just one-click. (Finally 다음 문장부터 3문장을 transition words들을 사용해서 연결해 주는 것이 좋을 것 같아요. 예를 들면 authors of books in digital library will be discouraged because people won’t buy a book with their money if all the books are provided in digital form. 이라고 써 주시는 방법이 있어요)These points directly opposes the reading passage’s argument that sharing ideas with other authors will increase the quality of their writing skills, and it will motivate authors themselves.
