The balloons dissolved high in the sky.

气球在高空中消。

The sounds fainted away in the distance.

声音在远处消。

The shapes faded (away) into the night.

这些形象在夜色中消。

Your hunger decreases as you eat.

饥饿感在吃饭消的。

The laughter died down.

声消。

The noise gradually faded away.

闹声消。

When you turn on a transistorized radio, the sound comes on immediately; when you turn off, it fades out gradually.

你打开晶体管收音机, 立刻就有声音, 当你关掉它, 声音消。
