Though I know I have to improve my English ability not only for the transfering exam in July but any subject about anthropological research as well,

I still don't know how to prepare, especially keeping my attention on idioms and phrases that I have no idea how to figure out.

有這種事!?

So, is there any suggestion?

You can borrow books from library

and watch films and such

Soaking in the world of English,eh?
