Need help reading a pattern

[Beth4400]

Hi there! I'm still somewhat new to knitting and was wondering if someone might explain to me the 4 rows required to knit a table runner i'm working on (esp rows 2 & 4)...it just doesn't seem to be coming out right...Thanks so much!

Row 1 (RS): K2, *k2 [yo] twice, k2; repeat from * to last 2 sts, k2-76 st
Row 2: K2, *p2tog, p1 (yo from previous row), k1 (yo from previous row), p2tog; repeat from * to last 2 sts, k2-52 sts remain
Row 3: K2, yo, *k4, [yo] twice; repeat from * to last 6 sts, k4, yo, k2-76 sts
Row 4: K2, p1, *[p2tog] twice, p1 (yo from previous row), k1 (yo from previous row); repeat from * to last 7 sts, [p2tog] twice, p1, k2-52 sts remain
