1、没有be surprised in这种用法，surprised不和in搭配，可以和to，at搭配。
2、be surprised at 用法
（1）be surprised at + somebody 表示对某人的行为感到惊讶。
例句：I am surprised at you. 我对你的行为感到惊讶。
（2）be surprised at + something 表示对某事感到惊讶。
例句：I was surprised at your tone. 我对你的腔调吃惊不小。
（3）be surprised at +doing something 表示对干某事感到惊讶。
例句：I was surprised at seeing him there.我真想不到在那里见到他。
3、be surprised to do something 对干某事感到很惊讶
例句：I'm surprised to hear you say that.我真想不到听到你说出这番话来。
可以看出，be surprised to do something跟be surprised at doing something意思相同。
