Gender and Language

I have an exam in 4 days, and I need some readings or examples on 2 topics: Gender and Language and Language and its place in the society. Basically, the first one is about how people of different genders speak differently, i.e. guys swear more and girls are more polite, etc. I guess the second one doesn't need much explanation.

Anyone know of any online articles where I can get some examples or insights from? Help is much appreciated. Thanks in advance.
