　　Hit The Nail On The Head: 说得中肯，一针见血；解释正确

　　And when someone says your words or actions hit the nail on the head, he means what you said or did was exactly right. (VOA: special.2009.09.20)

　　当有人说你的话或行为是"hit the nail on the head"时，他是指你所说的或做的事情“一针见血”。

　　This analogy is a wonderfully straightforward one; missing the nail when hammering is imprecise and can cause damage to the surface beneath the hammer. Hitting the nail on the head leads to the desired results.

　　这个类比十分直白。当锤击钉子时若是不精确，就要砸到铁锤下方的地表。但如果砸在钉头上就会如愿将钉子砸进去。

　　例句：

　　1. Every word he said hit the nail on the head.

　　他说的真是头头是道。

　　《汉英大词典》

　　2. Your analysis really hit the nail on the head.

　　3. With regard to the gentleman's comments, I think he has hit the nail right on the head.

　　说到这位先生的评语，我觉得他真是讲的很中肯呢。
