知更鸟、歌雀、红翼鸫在部分光秃而潮湿的田野里轻吟出银铃般的旋律，犹如冬天最后的雪花簌簌地飘向大地。

The faint silvery 1)warblings heard over the partially bare and moist fields from the 2)bluebird, the 3)song sparrow, and the 4)redwing, as if the last flakes of winter tinkled as they fell!

有一种鸟叫红襟知更鸟。

One of these birds is the robin.

注意观察那些矮小的树林，你就会找到红襟知更鸟的窝。

If you want to find a robin's nest, look in a small tree.
