You need to add 'other' to the sentences that do not have it; then, all 7 statements will be OK:
1. No other boy is taller than Tom in his class. 3. No other boys are taller than Tom in his class. 5. Tom is taller than any other boy in his class. 6. Tom is taller than any other boys in his class.
- 'Take' is away from the speaker and/or listener. - 'Bring' is toward the speaker and/or listener. - Subconscious courtesy is involved, since the speaker will often choose the verb to match the listener's viewpoint. - Perspective is also involved, as the speaker will often visualize himself (or the listener) where he (or the listener) isn't at the moment of speaking.
