Hello Anastasia. After the verb ''consider'' you can use: -ing form - They are considering selling the house. - I am considering applying for the job. a noun/a noun phrase - I'm considering the various possibilities. - Have you ever considered a career in the police force? question word - If you consider how long he's been learning the piano, he's not very good. object + (to be) + noun/adjective - We don't consider her to be right for the job. - He is considered (to be) the best British athlete. passive + object + to infinitive - It is considered bad manners in some cultures to speak with your mouth full of food. You can also use ''that'' after consider. I hope this will help :)

"Consider" is a transitive verb ("consider what?"), so if you use another verb after "consider", you need it in gerund form: (verb)+ing.
