口语素材：Doing Research 做科研

I prefer academic books or journals.

First and foremost, the information in the Internet is either incomplete or not valuable. Books have complete research paper and have enough depth to help me with my research.

Second, even if there is valuable information in the Internet, it is not free, you have to pay. Since I am a university student and our school has a wonderful library. I can always borrow books at school. Why I waste money in the Internet then?

Finally, suffering the Internet is indeed time consuming. It cost me lots of time to search for the useful information. Borrow a book in the library or buy one in the book store is much easier and can save a lot of time for me.
