If you read something such as a book to someone, you say the words aloud so that the other person can hear them. You can either say that you read someone something, or that you read something to someone.
You also use remind to mean that you mention something that someone needs to do, so that they do not forget to do it. In this meaning, you say you remind someone about something or remind them to do something.
I reminded him that we had a wedding to go to on Saturday.
You can also say that someone risks doing something when they do it even though they know it might have bad results. For example, if you risk phoning someone, you phone them even though you know that it might cause problems.
