主语(人) + be动词(根据时态/人称变化:am/is/are/was/were/will be等) + surprised + at + 宾语(名词/代词/动名词/宾语从句)。
关键注意:at 是介词,后面必须接名词性成分(不能直接接动词原形)。
根据“at”后接的宾语类型,举不同场景的例子:
I’m surprised at the news (我对这个消息感到惊讶).
She was surprised at the size of the crowd (她对人群的规模感到意外).
We are surprised at you—you never lie! (我们对你很惊讶——你从不说谎!).
He was surprised at it (他对这件事感到意外).
They were surprised at seeing their old teacher (他们见到老教师感到惊讶).
I’m surprised at hearing the noise (我对听到噪音感到意外).
She’s surprised at how fast he ran (她对他跑得多快感到惊讶).
I was surprised at what you said (我对你的话感到意外).
否定形式:在be动词后加not,如:I’m not surprised at his mistake (我对他的错误不感到惊讶).
疑问形式:将be动词提前,如:Are you surprised at the result? (你对结果感到惊讶吗?).
时态变化:根据语境调整be动词的时态,如:
过去时:He was surprised at the gift (他对礼物感到惊讶).
将来时:You will be surprised at the party (你会对聚会感到惊喜).
注意区分 be surprised at 和 be surprised to do:
be surprised at + 名词性成分:强调“对某事物本身感到惊讶”(如:I’m surprised at your arrival 我对你的到来感到惊讶)。
be surprised to do:强调“做某事时感到惊讶”(不定式表原因,如:I’m surprised to see you here 我很惊讶在这里见到你)。
