Hi there Well, I hope you can help me please I got a doubt about adjectives + prepositions, for example: 1. I was surprised at/by/ (about?) the good news. 2. I was shocked at/by/ (about?) the bad news. I know that if I'm getting a good news I should use surprised and if it's a bad one I should use shocked, anyway, OALD dictionary says that in these both cases I can just use either "at sb/sth" or "by sb/sth" and I'm not pretty sure about that, I was thinking about it and I suppose that It might be possible to use "about sb/sth" too, I got the same situation with many other adjectives, so, Does each adjective got its own patterns or the preposition depends on the context? (if the pereposition depends on the context, What are the context of each one of these prepositions) [……] Edición del moderador This doubt really bugs me I thank you in advance.
