I don't want to seem rude, but does RTFM mean anything? Have you checked wget's help page?
has the answer to your question.
In this case, try using
wget -p http://www.whatever.html
I'll leave it to you to look up what it does & why.
I'm not trying to be a jerk (or worse) - it's just that like most Linux commands, wget has too many options to try to remember them all. As long as you can remember the '--help' option, you can easily find out what other options are available (and, usually, what they do).
