I was recently proofreading an ESL textbook and came across a photo of a woman. She had a surprised look on her face. Underneath were four options that the student was to pick. One of them was: "The woman is looking surprised." The other options were not possible choices.

I can't cite a general rule why this option is incorrect other than I have never seen or heard "look" used in this way. I asked someone else, and they said it sounded weird but didn't violate any rules of grammar. I feel it should be "The woman looks surprised." in the same way that we say "I know something," and not "I am knowing something."

Is the option "The woman is looking surprised." incorrect?
