请问astound和shock的区别

astound：to make someone very surprised or shocked [= astonish]:
例：We were astounded to read your letter.
我们看了你的信大吃一惊。
shock：to make someone feel very surprised and upset, and unable to believe what has happened: （惊奇的难以置信）
例：The hatred in her voice shocked him.
她声音中的怨恨让他吃惊得难以置信。

astound
astound /əˈstaʊnd/
verb [T]
to surprise or shock someone very much:
The news astounded me.
这是webster 上面的解释，从这句话就能看出来astound的程度远远高于shock
如果shock是吃惊，那么astound就是无比的震惊，被雷到了

surprised-->astonished-->astounded-->shocked 惊讶程度递增
