A lot of universities also offer summer-intensive language courses specifically for graduate students. You just have to get the required grade (whatever it may be for your institution) in order to satisfy these requirements. Many of those summer programs work on teaching specifically to language for graduate study, so much more emphasis on reading and translation than speaking.
You can often also choose to take those courses at schools that DO offer them, if yours doesn't. I know UChicago, for example, has a big summer language program.
