irritated 和 annoyed 两个词有区别吗?还是两个词完全可以互换?

irratated 牛津词典上解释为：annoyed or angry 烦恼 恼怒
后跟 at /by/ with sth
eg.She was getting more and more irritated at his comments.
annoyed 牛津词典解释为：slightly angry 较少用在名词前
常用 annoyed with sb/ at 或者 about sth/ 加 that从句/ annoyed to find or see
eg.I was annoyed with with myself for giving in so easily.
I was annoyed that they hadn't turned up.
He was annoyed to find himself going red.
二者意思基本一样,但annoyed比irritated 生气的程度更轻一点.另外一点区别就是二者常用短语及结构不一样.上面已经给出常用法.
