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,还加奏了两支曲子。

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

再往茶壶里添几勺茶叶，茶淡了最难喝了。

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

我经在所有门上安了新锁，为更安全起见，楼下所有的窗子也加了锁。
