PREPOSICIONES DEPENDIENTES
Recuerda que se puede decir arrive AT or arrive IN, pero jamás arrive TO. ARRIVE AT se refiere a un lugar específico como un edificio, el aeropuerto, una estación de tren o una terminal de autobuses, etc. ARRIVE IN se usa para cosas de mayor porte o tamaño (ciudad, región, país o continente). Ejemplos: What time did you arrive arrived AT the hotel? (no What time did you arrive to the hotel?); I arrived IN Japan at 8:00 am. (no I arrived to Japan at 8:00 am). Pero recuerda lo siguiente: ARRIVE HOME (sin preposición): He arrived home yesterday (no He arrived at home yesterday).

AT PARA HABILIDADES
Cuando evaluamos la habilidad de alguien para hacer algo utilizamos AT: Mirta is good AT maths, but she is bad AT volleyball; Mike is better than me AT swimming, but he is terrible AT French.

TRES PARTICULARIDADES DE LAS PREPOSICIONES EN UNA ORACION
1. Las preposiciones van seguidas normalmente de un sustantivo o pronombre. La única forma verbal que puede seguir a una preposición es el gerundio ING:
AFTER eating the chicken he drank a soda.

2. A las preposiciones les pueden seguir asimismo pronombres o cláusulas interrogativas (WH words or clauses):
FROM what he said I think he was pretty annoyed.

3. En inglés, a diferencia de muchos otros idiomas, una preposición puede rematar o terminar una oración. No te preocupes... pero practícalo!! Esta función tan especial del idioma suele confundir a casi todos los estudiantes:
What did you do that FOR?
Who are you looking AT?
This is the building where OM Personal office is IN.
She is the writer I was referring TO.
Who does Sylvia remind you OF?
