「课文原句」However， some actors can astonish us with the deep feelings they can inspire in us for a character they are playing. （P17）
「名师点拨」astonish vt.意为“使大为吃惊；使惊异”，比surprise程度强，比shock程度弱。如：I was astonished to hear that the professor had broken down because of his hard work. I was astonished by how much she'd grown.「知识拓展」（1） astonishing adj.意为“令人惊异的”。如：The astonishing news made the world astonished， and a great many people expressed their opinions on the Internet.（2） astonished adj.指（某人）处于惊异、吃惊状况，常用be astonished at sth.如：He was astonished at what Tom had said and done.（3） astonishment n.意为“惊讶”，可用to one‘s astonishment表示“使某人吃惊的是”。如：To my astonishment， she still remembered my birthday.
