She was too surprised to see how angry her farther was.

was surprised 是谓语部分
too.to do 表示“太.以至于不.”
to see how angry her farther was 这是不定式做状语.而how angry her farther was是see 的宾语从句.
句意：她很吃惊以至没有注意到父亲是多么地生气.你好，那how angry 放在he farther之前是为强调how angry 吗？谢谢！how angry her farther was这是一个从句，从句也是句子，所以有该有的主谓等成份。在一个句子中，how只能出现在句首，而how是副词，那么它所修饰的angry也要一起提到句首。How angry是very angry 的意思，前者表示生气的程度更大。如果用后者，语序就要变成：She was too surprised to see her farther was VERY ANGRY欢迎继续追问~~~.
