  In this paper, we prove some supercongruences via the Wilf-Zeilberger method.
For instance, for any odd prime $p$ and positive integer $r$ and
$\delta\in\{1,2\}$, we have \begin{align*} \sum_{n=0}^{(p^r-1)/\delta}
\frac{\left(\frac12\right)^5_n}{n!^5}(10n^2+6n+1)(-4)^n
&\equiv\begin{cases}p^{2r}\ \pmod{p^{r+4}} &\tt{if}\ r\leq4, \\0\
\pmod{p^{r+4}} &\tt{if}\ r \geq5. \end{cases} \end{align*}
