Let $\alpha$ be an irrational and $\varphi: \mathbb N \rightarrow \mathbb R^+$ be
a function decreasing to zero. Let $\omega(\alpha):= \sup \{\theta \geq 1: \liminf_{n\to
\infty}n^{\theta} \|n\alpha\|=0\}$.
For any $\alpha$ with a given $\omega(\alpha)$, we give some sharp
estimates for the Hausdorff dimension of the set
\[
E_{\varphi}(\alpha):=\{y\in \mathbb R: \|n\alpha -y\| \varphi(n) \text{ for
infinitely many } n\},
\]
where $\|\cdot\|$ denotes the distance to the nearest integer.
