New knitter--need help with pattern interpretation

Just starting and although I can read the pattern I do not understand the following:

Raglan and front shaping: Cast off 3 sts beg next row.
“Work one row even” What row is worked even?
Then it lists 1st row: and instructions then 2nd row and instructions and so forth for several rows.

What is the meaning of “work one row even?”

Work one row even is throughout the pattern for the left and right front.

Any assistance would help–hope I explained throughly???

Work one row even means you work one row just as you have been doing them up to this point. No further inc, dec or changes.

Thanks–might be in over my head on this one-but I will try anyway.
