Another proof of Zagier's evaluation formula of the multiple zeta values   $\zeta(2,...,2,3,2,...,2)$
  Using some transformation formulas of the generalized hypergeometric series $\,_3F_2$, we give another proof of D. Zagier's evaluation formula of the multiple zeta values $\zeta(2,...,2,3,2,...,2)$.
