[翻译] 那个老人能够用手走路，我们都感到惊奇。
[分析]amazed的意思是“惊奇的，惊讶的”；shocked的意思是“震惊的”，它跟amazed的区别在于shocked所指的震惊一般是指突然发生的，语气要比amazed强；例如: I was shocked at the news of his death.我听到他去世的消息十分震惊。Amazed表示在似乎不可能或不大可能的事物面前所表现的巨大的惊奇或迷惑。有还有“惊叹”、“佩服”之意。例如：The teacher was amazed to find that a lazy student had gained a mark of 100 in an important test.老师惊奇地发现一个懒惰的学生竟在一次重要的考试中得了100分。We were amazed at the ingenuity with which they overcome their difficulties.他们在解决困难中所表现的智慧使我们惊叹。Frightened的意思是“受惊吓的”；pleased的意思是“高兴的，满意的”。
