for good measure

The pianist gave a long and varied recital,with a couple of encores for good measure.

那钢琴家的独奏演出时间长、节目多,还加奏两支曲子。

Put a couple more spoonfuls of tea in the pot for good measure. There’s nothing worse than weak tea.

再往壶里添几勺叶，最难喝。

I’ve put new locks on all the doors, and just for good measure, I’ve put locks on all the downstairs windows too.

我经在所有门新锁，为更全起见，楼下所有的窗子也加锁。
