How do I put a PDF file in a word document?

If you can't figure out how to directly place a PDF into Word, open the pdf file in Photoshop (assuming you have Photoshop) and save it as a jpg or tiff then place it into Word which I know you can do. By the way, you are being redundent by calling it a "PDF file". PDF stands for portable document file so by saying PDF file you are actually saying portable document file file. You are saying file twice. Just a little FYI.

Do you have a scanner or a printer all-in-one? If you want to include an image of the file in a document, you have to make it an image. I would print it, then scan it and save it as a jpg.

In your document, you would Insert, Picture from file, indicate the full location, name, type of file, and insert.

In case you dont have adobe photoshop, you can also use the snapshot feature of adobe reader. Just click the camera icon just below the menu, select the part of the pdf or the entire page if you need to but then you have to zoom in and then paste the snapshot into your word document.
