不期而遇

Happen to meet／come across

Huge numbers of birds had flocked together by the lake.

成群的鸟聚集在湖畔。

Birds gather in large numbers beside the river.

鸟儿一群群地聚在河边。

Sunshine and the singing of birds are cheery.

阳光和鸟鸣令人愉快。

After human being, birds use their voices more often than any other animal.

动物之中除了人类，鸟是使用嗓子最多的一个。

Within the dark woods the liquid silver voices of the birds called unceasing.

黑暗的树林里不断传出行云流水般的清脆鸟语声。

Birds cry plaintively before they die, men speak kindly in the presence of death.

鸟之将死，其鸣也哀; 人之将死, 其言也善。
