while away

They while away many afternoons on the beach.

他们海滩消磨了许多下午。

I had ten hours to wait in Rome, so I whiled away the time wandering around the museums.

我罗马要小时，只好逛逛博物馆来打时间。

The Memex user could also mount a camera on his or her forehead to capture pictures while away from the desk.

Memex的使用者还能把相机头上，即使离开书桌，也能捕捉画面。
