A Can I help you?
B I hope so.I'm looking for some material for a paper I'm writing, and I'm not quite sure where to look.
A I'll certainly try to help you. What topic is your paper on?
B My paper is on the influence of television on children.
A There are several possible sources you might use for that topic. I suggest you use the computer and the computer will give you a list of every scientific journal that talks about children and television.
