Librarian

The librarians at our university are very helpful. When I first started my psychology course in college, I was asked to do a literature review about dream interpretation review some literature about dream imterpretation. So I went to the library and checked out the materials my professor put on reserve for me, as well as some other psychology journals in the reference section. Still, I was unable to get enough sources. Then, a librarian came to me and taught me how to access the psychology databases and electronic journals. Besides that, He also told me that by displaying the abstracts and skimming notes, I would save a lot of time while doing my project. At last, I decided to try out the electronic search with the help of this kind librarian.

Your English is very impressive! All of the things that I had to correct are very subtle (and advanced) nuances within the language. I highlighted "displaying the abstracts and skimming notes" simply because I do not know what it means, but grammatically there is nothing wrong with the sentence. Great job!

Your English is very good.  Your writing is much better than a lot of native English speakers.  Well done.
