"Surprised" is an adjective in Engpsh, not an adverb. To describe the way in which someone is surprised, you can use an adverb such as "surprisedly" or "in surprise."

However, "surprisedly" is not a commonly used adverb in Engpsh and is not found in most dictionaries. "In surprise" is a more common and accepted way to describe the manner in which someone is surprised.

For example:

"She looked at him in surprise when he told her the news." (她听到他告诉她的消息时，惊讶地看着他。)
"He reacted in surprise when the door suddenly opened." (门突然打开时，他惊讶地反应了过来。)

"In surprise" is a prepositional phrase that functions as an adverb. It is formed using the preposition "in" and the noun "surprise." The noun "surprise" is being used here to describe the emotion or state of being surprised.

The phrase "in surprise" is often used to describe a person's facial expression or body language when they are surprised, such as opening their mouth or eyes wide, or standing with their arms outstretched. It can also be used to describe someone's reaction to something unexpected or surprising, such as a sudden noise or event.
