Well I can see why rows 3 and 4 are easy!
This sounds like one of those patterns that you just have to do exactly what they say, step by step.
On row 3, instead of wrapping your yarn once like your normally would, wrap it 3 times and pull all three loops through. Do this for every stitch.
On row 4, it looks like you slip the three extra loops off the needle from the row before, then move the stitch onto the right needle to hold there while you do the same thing 3 more times. When you have 4 big loops on the right needle, you put them on the left and knit, p, k, p into all four at once--don't slide them off between stitches.
Give it a try and see how it turns out.
