In a class at Imperial College London, students sit hunched over laptops, typing lines of code.

网友把hunched 误认为是动词了，其实这里是形容词，作 sit 的方式状语。

词典注释：ADJ If you are hunched, or hunched up, you are leaning forward with your shoulders raised and your head down, often because you are cold, ill, or unhappy. 缩头弓身的

相同用法的例句：

He sat hunched over his breakfast. 他弓着背吃早饭。《牛津词典》

He got a stiff neck and a sore back from sitting hunched up for so long. 他因为长时间弓身坐着而脖子僵直，背部酸痛。《柯林斯高阶英汉双解学习词典》
