Half is the singular, and halves is the plural.

The meaning depends on the verb tense. "Ha sido" refers to action which has recently passed (it is like the present perfect), while "fue" is just like the past simple. You usually use "ha sido un placer" after meeting someone, but in the North of Spain they don't distinguish between a recently past and the past, so they always say "fue un placer" (which isn't correct).

1. Voua avez besoin d'une preposition car c'est un complement de lieu: venir a qq lieu. "Le" et "a" ne sont pas synonimes. Vous utilisez "au" pour simplifier "á le" (ensuite, vous ne pouvez pas écrire ça jamais). Au = á le (seulement utilisé pour le masculin) 2. Vous avez raison, car le mot commence par une voyelle vous devez l' abrevier

Another difference is that a becario is usually paid a low salary, while the "prácticas" can be paid (in Spanish they are called prácticas remuneradas, and the salary is lowest) or not (named prácticas no remuneradas). The prácticas no remuneradas are a part of your studies, and they are done normally just before obtaining your degree. Moreover, it is not the same being becado or being a becario. Becado is when you work with an enterprise because you won a grant. Becario is related with your type of contrat that allows companies to have cheaper workers, and usually because they have a lack of practice, but at the moment and due to the economical crisis many people are engaged as becarios, and it does not matter their professional experience.

Does"right off" mean immediatly? I will traduce like "La tienda está justo en la calle Oak" or "La tienda está sin ninguna duda en la calle Oak"

ai usually listen to new unkown songs and I try to write the lyrics. Then I compare my notes to the original song. Try also watching films and series in the original version, or with English subtitles.

The prepositions changes with the meaning of the verb. Salir de means exit or go out, while salir para means go to. For example, Yo salgo de casa / El bus sale para Madrid en cinco minutos. In thencase with regresar, "a" is used with phisycal places like home, and "de"with non-physical places, like holidays. And you are right, le is referring to "el niño", it is just emphasizing the indirect object. It is usual in Spain with some verbs.
