There is a way, you can download a No CD crack.
Google "Sims 2 No CD Crack" and look around. I can't tell you which ones work or not, or if what you download is entirely safe. So only do it if you have decent anti virus and be careful.
Although Sims2 cracks will be very easy to get. It's no installing etc, all you're doing is replacing SIMS2.exe with the downloaded one and it will allow you to play without the CD.
So If you find one it should be called SIMS2.exe or something similar.
If you right click your Sims icon > properties and open the file location. You just drag your downloaded file into there, copy and replace. then you can run it and it should load normally.
Remember to copy + save your original too, just incase.
