she tried to hide her anger.?她试图掩饰自己的愤怒。她笑了笑以掩饰自己的紧张

She is showing her true colors.

她终于原形毕露了。

show one's true color 直译过来就是：“露出……真正的颜色”。据说当年英国舰队航于海上时，为避开法国逡巡船队的注意，就升起法国旗帜伪装是自家人，等到关键时刻就改旗易色，显露本色。于是产生了show one's true colors 这个习语，意为“亮出自己的真正旗帜，原形毕露，显露真面目”。因此，当美国人说"She is showing her true colors."时，他/她要表达的意思就是:"She is unmasked."、"She is showing the cloven hoof."。
