astound解释为to make someone very surprised astonish解释为to surprise someone very much 请问
这两者的程度是一样的吗?还是有轻重之分?

以下是我学习时候总结的,加上了“amaze”,请参考：
astonish,amaze,astound:These verbs mean to affect a person strongly as being unexpected or unusual; 这些动词意思是因其出其不意或不寻常而强烈地影响一个人.作为动词在一起比较的一般含义是“使吃惊”.
astonish：Astonish suggests overwhelming surprise; 表示难以抵御的惊讶.表示“使人大吃一惊”、“几乎无法使人相信”,但没有“惊叹”的意思.就是说,通常表示某事使人震惊得难以置信.它一般以事物或他人作主语,而以本人作主语时用被动形式.
1.The sight of such an enormous crowd astonished us.看到如此庞大的人群我惊讶万分.
2.The successful laying of the Atlantic cable astonished everybody:its later breaks astonished no one; but after it was finally in operation.Many said that no future invention could surprise them.在大西洋底下成功地铺设了电缆,这使得大家都感到骇然；后来有几处电缆折断了,谁也不感到惊奇.不过在这些电缆终于投入工作之后,许多人都说,未来的任何发明再也不会使人吃惊了.
3.I was astonished at his rudeness.他的粗野使我大吃一惊.
4.He was astonished at what he found.A man was lying in the box on top of a pile of woolen goods.他所看到的使他大为震惊,箱子里的一堆毛织品上面躺着一个人.
amaze:Amaze implies astonishment and often bewilderment; 表示极度惊讶以及困惑.所表示的吃惊中包含着使人迷惑不解、困窘或惊疑不定.强调“使惊异,困惑”间或还有“惊叹,佩服”的意思,是意义很强的词.它一般以事物或他人作主语,而以本人作主语时用被动形式.
1.The violinist's virtuosity has amazed audiences all over the world.小提琴家的精湛技艺使全世界的观众惊诧不已.
2.We were amazed at the ingenuity with which they solved their difficulties.他们在解决困难中所表现的智慧使我们惊叹[佩服].
3.When the archaeologists reconstructed the fragments,they were amazed to find that the goddess turned out to be a very modern-looking woman 当考古学家把那些碎块拼起来的时候,他们惊诧地发现那女神原来是一个现代装束的妇女.
4.Scientists have been amazed to find that it can cut through the hardest rock with great ease.科学家惊诧地发现,它可以轻而易举地钻穿最坚硬的岩石.
astound:Astound connotes shock,as from something unprecedented in one's experience; 暗指由于未经历过的事情产生的震惊.比 astonish 的词义强得多,常用于表示某件事你虽然认为有可能,但与你所发现的实际情况之间有很大差距.
1.He was astounded when he heard his son had taken drugs.他听说他儿子吸毒,不禁大为惊讶.
2.We were astounded at the high cost of traveling in Japan.日本昂贵的旅游费用令我们震惊.
