《夏日南亭怀辛大》 唐 · 孟浩然

山光忽西落，池月渐东上。

散发乘夕凉，开轩卧闲敞。

荷风送香气，竹露滴清响。

欲取鸣琴弹，恨无知音赏。

感此怀故人，中宵劳梦想。

Westward, the mountain light dips out;a pond moon rises slowly in the east.

Letting down my hair, I welcome the cool of evening,opening the window, I stretch out at leisure.

Lotus wind perfumes the air,bamboo dew drips crisply to the ground.

I want to pick up my singing zither,but there's no-one around who's close to my music.

I'm moved by my remembrance of you, old friend,laboring through my midnight dream.

 

白话译文

夕阳忽然间落下了西山，东边池角明月渐渐东上。

披散头发今夕恰好乘凉，开窗闲卧多么清静舒畅。

清风徐徐送来荷花幽香，竹叶轻轻滴下露珠清响。

心想取来鸣琴轻弹一曲，只恨眼前没有知音欣赏。

感此良宵不免怀念故友，只能在夜半里梦想一场。
