Dear Teachers,

1.– She still stands on ceremony when talking with/to me.
-He still minds his manners when he talks to/with me.
-Are these natural and the same meaning?

2.In some action films the police often say “freeze!”, does this mean “stand still!” or “don’t move!”?

3.I want to tell my friends to get into my house, so I’ll say these, right?
-You guys, get in!
-You guys, go inside / get inside!
-You guys, come on in!

4.I’m so sure that she just / only loves me beside her family members.
-Is this natural?

Thanks a lot to Teachers,

1. I would use to in both of these sentences, though with would also be correct and natural. If one says "Jim will talk to her," there is the feeling that Jim will do most of the talking. Talk with conveys more of a feeling of an exchange. In your sentences, she stands on ceremony and he still minds his manners when talking to me; you are describing her or his talking to me. My replies may not be ceremonious or mannerly.

2. Of course, this is short for "You freeze!" Webster's Third New International Dictionary has
to become motionless as if suddenly frozen: to stand or remain without movement or activity of any kind.

3. You guys, get in! This is fine; get here means to bring oneself.
You guys, go inside/get inside! Both of these work and are essentially synonymous.
You guys, come on in! This works too, but is more of an invitation than a command.

4. Only is normally placed before the word or words it modifies. Besides is used more than beside in the meaning "in addition to."
I'm so sure that she loves only me (besides her family members).
May I comment on number 2? As far as I know, the "Freeze." means just that freeze from where you are and what you are doing at that point in time. If you were bending forward to pick up a coin and when someone very strong shouts "Freeze," then you should stop moving and maintan that posture until he gives the permission to move. I wouldn't do what I ???did at the beginning -- proceeding to comment w/o first getting the permission.
