查词典后发现有很多解释

• the outline of someone's back某人的背影轮廓

• a figure viewed from behind背影

• back figure背影

• the sight of one's back背影

• rear view／figure seen from behind／view of the back (of a person or object)背影

具体应用中其实更经常用的就是figure和back，具体是哪个还要看语境。

1. He gazed at his father's receding figure with tearful eyes.他噙着泪水，凝望着父亲远去的背影。

2. She scowled furiously at his back as he walked away.当他走开时，她对着他的背影怒气冲冲。

3. “He is O.K.,” said the store's owner, Kim Kyong-soon, 72, looking at the man's back. “Unlike others, he doesn't cheat when he counts out his coins.”“他挺好的，”72岁的店主金敬顺（Kim Kyong-soon，音）看着这个男人的背影说。“和其他人不一样，他掏硬币付钱的时候不耍花样。”

4. She scowled furiously at his back as he walked away.当他走开时，她对着他的背影怒气冲冲。

甚至有时并没有翻译出来，靠上下文理解

1. The mother gazed after her son until he was out of sight.母亲目送着儿子的背影，直到看不见为止。
