屋子里亮着灯火。

The lamp is on in the room.

街上亮着路灯。

The streetlights are on.

.对岸亮起一片火光。

A fire is blazing up on the opposite bank.

天亮了，但是太阳还没有出来。

The sky is light but the sun is yet to come up.

天快亮了，该起床了。

It's almost light – time to get up.

外面已经亮了。

It's already light outside.

刀磨得很亮。

The knife has been sharpened until it shines.

亮起嗓子唱

raise one's voice and sing out

把钢刀一亮

flash one's knife

只见钢刀一亮

just see the flash of a knife

亮出旗帜

show one's flags

亮出马刀的骑兵

cavalry displaying their sabres

亮着架势

strike a pose

把自己的思想亮出来

reveal one's own thoughts

你真有本领，不妨拿出来亮一亮。

You're really good, and you let it show.

灯光太亮。

The light is too bright.

灯不亮。

The light is not on.

这间屋子里还够亮的。

It's not bright enough in this room.

她的嗓子很亮。

She has a loud and clear voice.

心里亮了

be clear about something
