他在这事情上从来没有表态过。

Tā zài zhè shìqing shàng cónglái méiyǒu biǎotài guo.

He's never stated his position on this matter.

他的表态引起了大家的关注。

Tā de biǎotài yǐnqǐ le dàjiā de guānzhù.

His statement drew everyone's attention.

这毕竟是别人的家事，我不方便评论和表态。

Zhè bìjìng shì biérén de jiāshì, wǒ bù fāngbiàn pínglùn hé biǎotài.

After all, this is someone else's family matter, so it's not appropriate for me to comment or take a stance.
