汽艇飞快地驶向远方。

The motorboat sped off into the distance.

她飞快地走开了。

She sped off.

渔船鼓着白帆，飞快地向远处驶去。

Its white sail billowing in the wind, the fishing boat sped off into the distance.

日子过得飞快，转眼又是一年。

Time flies by so fast, in the blink of an eye a year goes past.

刀磨得飞快。

The knife was sharpened until it was razor sharp.
