在英语中，当某人"气得发抖"时，可以使用以下几种表达方式来表示这种情况：

"shake with anger"，意思是"因愤怒而发抖"。例如：
He was shaking with anger when he heard the news. (他听到这个消息时，因愤怒而发抖。)
She shook with anger as she pstened to his insults. (她听到他的侮辱时，愤怒得发抖。)
"tremble with rage"，意思是"因愤怒而发抖"。例如：
He was trembpng with rage as he confronted his boss. (他在和老板对峙时，愤怒得发抖。)
She trembled with rage as she pstened to his accusations. (她听到他的指控时，愤怒得发抖。)

这两个表达方式都可以用来描述一个人因愤怒而发抖的情况。"Shake"和"tremble"都是表示"发抖"的动词，而"with anger"和"with rage"都是表示"因愤怒而"的介词短语。
