In order to have the entire pattern translated and written in English, you would need permission in order to avoid copyright issues.
As this pattern is free on Ravelry, I would
1) Write the desgner to see if she has the pattern in English, or can translate it for you (for a fee). Bonus to her, she could then sell the translation on Ravelry.
2) Use an online translator/website like this one to translate what you can.
3) Use this Ravelry forum to get help with specific lines, one at a time.
4) Wing it! It's a simple stockinette sock with YOs, so find a stockinette pattern you like and modify it with this motif. A chart is provided in the pattern, which essentially indicates all you have to do is a k2tog, YO on one row, followed by an offset YO, SSK on the next row.
